Thrift Savings Plan officials recently released the 2018 Thrift Savings Plan Contribution Limits. Thrift Savings Plan contribution limits are calculated on an annual basis based on cost of living indexes and can increase based on rules set by the IRS.
There are only a few small changes to the TSP contribution limits in 2018. The limits for employee deferrals is now $18,500, up from $18,000 in 2017. The catch-up contributions remain the same, at $6,000 per year. (Catch-up contributions are only available to persons aged 50 and up). There is a $1,000 increase in the Max Annual Addition Limit, which increases from $54,000 to $55,000.
Let’s do a deep dive into this topic. While contribution limits seem straightforward on the surface, this is actually a very interesting topic. Certain members may have complicated situations that deserve special attention (multiple TSP accounts, multiple retirement accounts, contributions while deployed, participating in both the Roth and Traditional TSP, etc.).
2018 Thrift Savings Plan Contribution Limits
The 2018 Thrift Savings Plan Contribution Limits are as follows:
Elective Deferral Limit: $18,500. This is the limit employees can defer from their paychecks. It applies to Traditional and Roth TSP accounts (they share the same limit, so you can’t contribute $18,500 to each). This includes your base pay, special pay, and bonuses. To max out your TSP, you would need to contribute $1,541.67 per month from your pay checks. That is very aggressive, but it can be possible for some, depending on your rank / pay grade, and living expenses.
Annual Addition Limit: $55,000. This is the maximum amount you can put into your Thrift Savings Plan from all sources (except catch up contributions – see the section below, this is the $6,000 you can contribute if you are age 50 or over). Deployed military members can exceed the $18,500 annual Elective Deferral Limit. Excess contributions made while deployed count toward the Annual Addition Limit (contributions above $18,500 automatically go into the Traditional TSP). This limit also includes Agency contributions (matching contributions made by the Civil Service, or matching contributions from the military, as part of the Blended Retirement System, starting in 2018).
Catch-up Contribution Limit: $6,000. Members age 50 and over can contribute an additional $6,000 per year to their elective deferral limit (total of $24,500) and Annual Addition Limit ($61,000).
Explanation of Thrift Savings Plan Contribution Limits
The following chart displays the 2018 Thrift Savings Plan contribution limits, with notes about each type of contribution. The combined maximum one can contribute, including all agency matching contributions, contributions from special pay and bonuses, and contributions while deployed, is $54,000 ($60,000 for those who are eligible for catch-up contributions).
| 2018 Thrift Savings Plan Limits | Max Contribution | Notes |
|---|---|---|
| Elective Deferral Limit* | $18,500 | Elective deferral contributions only apply to regular employee contributions that are made in before-tax (i.e., tax-deferred) dollars. For members of the uniformed services, this includes all tax-deferred contributions from taxable basic pay, incentive pay, special pay, and bonus pay. |
| Max Annual Addition Limit | $55,000 | An additional limit imposed on the total amount of all contributions made on behalf of an employee in a calendar year. Uniformed service members become subject to this limit when tax-exempt contributions are made to their TSP accounts. This limit includes employee contributions (both tax-deferred and tax-exempt), Agency Automatic (1%), and Agency Matching Contributions. |
| Catch-up Contribution Limit | $6,000 | The maximum amount of catch-up contributions that can be contributed in a given year by participants age 50 and older. It is separate from the elective deferral and annual addition limit imposed on regular employee contributions. |
Current & Historic Thrift Savings Plan Contribution Limits

| 2018 | $18,500 | $6,000 | $55,000 | $61,000 |
Types of Thrift Savings Plan Contributions
There are two types of TSP contributions:
- Regular employee contributions (including automatic enrollment contributions)
- Catch-up contributions (for participants age 50 or older)
Regular contributions. Eligible TSP participants can begin making regular employee contributions at any time. These contributions are made from basic pay before taxes are withheld. Your contribution will remain in place until you elect to stop or change the contribution amount, reach the contribution limit, or take a Thrift Savings Plan financial hardship withdrawal.
Catch-up contributions. Catch-up contributions are only available to those age 50 and above. You must elect to make catch-up contributions each calendar year. If you don’t elect to make catch-up contributions each year, they will automatically stop. You can made regular and catch-up contributions at the same time. If you plan the amounts you contribute carefully, you will maximize both the $18,500 regular contributions and the $6,000 in catch-up contributions during the last pay period of the year. This is much simpler than having to keep track of when your regular TSP contributions will max out, stopping the regular contributions, and then starting catch-up contributions.
Uniformed Services TSP Contributions
The Thrift Savings Plan is available to all military members. Military members are eligible to contribute any whole percentage of basic pay, as long as the annual total of the tax-deferred investment doesn’t exceed the maximum contribution limit. Military members also have the option of contributing any portion of their incentive pay, bonuses, or special pay so long as they contribute a portion of their basic pay.
Roth TSP Contributions for TSP members. Roth Thrift Savings Plan contributions are limited to the $18,500 elective deferral limit. All additional contributions toward the Annual Additions Limit must be made into a Traditional TSP account, even if the contributions come from tax-exempt pay.
Tax free combat zone contributions. Military members serving in tax-free combat zones are allowed to contribute up to $55,000. This total includes regular deferred contributions, tax-exempt combat zone contributions and special pay and bonuses.
Note regarding catch-up contributions and tax free pay: Military members who are receiving tax-exempt pay while serving in an eligible combat zone must make catch-up contributions into a Roth Thrift Savings Plan account.
TSP Federal Agency Contribution Chart
FERS Employees receive an automatic 1% contribution from the federal government, then a 100% match for the first 3% they contribute, followed by an additional 0.5% match for the next 2% the contribute, bringing the maximum agency contribution to 5%. Federal employees can contribute as high of a percentage of their salary as they wish, so long as they don’t exceed total contribution limits, including the catch-up limits allowed for those age 50 and above.
The following chart can be used by Federal Employees to determine the total amount of their contributions including agency match.
TSP Agency Contribution Chart
How Contribution Limits Are Impacted With Multiple Retirement Accounts
The TSP is similar to a 401k plan, and they share the same annual contribution limit per person. This means if you cannot contribute more than $18,500 ($24,500 with catch-up contributions) across both accounts in any given calendar year.
This doesn’t impact most active duty members or civil service employees with only one job. However, this is very important to note for anyone who transitions to or from the military or civil service in any given year. And it’s important for traditional members of the Guard and Reserves, as they often have another retirement plan through their full-time job.
Be careful! TSP participants should be careful not to exceed their annual contribution limits across whichever retirement accounts they have. The TSP system will not allow you to contribute too much to the TSP. If you do, the TSP will refund you the difference, and reject future contributions through the end of the calendar year. But the TSP doesn’t have insight into your other retirement accounts.
Military TSP + Federal TSP. Many members of the Guard and Reserves are also Technicians and have access to both a military TSP account and a civil service TSP account. They can make contributions to both TSP accounts in the same tax year. However, these accounts share the same annual limit across both accounts. It’s very important not to exceed these contribution limits. The only time you can go above the annual employee deferral limit is when you are called to active duty and deploy to a tax-exempt zone. At this point, you will be able to contribute up to the Annual Addition Limit shown above ($55,000, or $61,000 with catch-up contributions).
TSP + 401k (or similar retirement account). Again, the TSP and 401k plans share the same annual limit. In theory, it seems like one should be able to contribute up to the Annual Addition Limit if you have contributed to the maximum allowed between your other retirement account and the TSP. But the TSP won’t be able to track this on their own. So you will need to contact them and verify that it is possible, and request they allow it. Again, this is a theory. I have not seen it in practice.
Other Notes about TSP Contributions
The following information should help you determine how to allocate your TSP contributions:
- Contributing by percentage of pay. If you elect to contribute a percentage of pay to the TSP and the amount is more than your remaining salary after mandatory deductions (e.g. Federal income tax, state taxes, TSP loan payments, etc.) and other voluntary deductions that are processed before TSP contributions, then the resulting pay will be the amount withheld and contributed to your TSP account.
- Contributing by dollar amount. If you designate a whole dollar amount that is greater than your remaining salary, then no employee contributions will be made for that pay period, and if you are FERS you will not receive Agency Matching Contributions for that pay period. If this occurs, you will need to lower your contribution level by electing to contribute either a lower percentage or dollar amount. No TSP contributions will be withheld from your pay until your new election is effective. Neither the new election or any matching contributions will be applied retroactively.
- Automatic contributions. The Thrift Savings Plan offers Automatic TSP Contributions for New Employees. The military will also have automatic enrollment when the blended retirement plan begins in 2018.
- Roth TSP. Here is more information about the Roth Thrift Savings Plan (TSP).
The Thrift Savings Plan is a great opportunity to save money for retirement and you should take advantage of it if you are eligible to participate. You can read more about the contribution rules at the TSP page.
Andrew says
Unfortunately no change from 2010. But in this low inflation/COLA environment that is not surprising.
Mike says
Ryan – why does DFAS refuse to let deployed members earning more than the tax free base pay cap make deferred contributions – DFAS insists the first dollars of TSP contributions come from tax free pay! Only if you elect like 100% TSP deduction can I get to my taxable pay!
This seems anti-service member as some of us are trying to lower our AGI so we can enjoy certain deductions and credits.
Ryan Guina says
Mike, I’m not 100% certain, but I believe there are rules regarding how contributions are made, and in which order they come from your pay. I recommend contacting someone at DFAS or the TSP.
David says
Ryan,
Do you know if the TSP allows military members to make contributions for the previous tax year before the tax deadline as other retirement account types do? For instance, I do not currently have a TSP but am interested in opening one and contributing a lump sum for 2011 contributions in order to reduce my 2011 taxable income while also investing.
Thanks!
Ryan Guina says
That’s a great question, David, but the answer, so far as I am aware, is no. Contributions must be made during the calendar year. You may still be able to open a Traditional IRA to reduce your tax obligation. You have until the tax deadline to fund an IRA for last calendar year. Here are some good options for opening an IRA.
Adrienne says
I want to change my TSP to roll over into a ROTH or IRA while I am in a tax free zone. I was told I could do this online. However, how do they know I am actually in a tax free zone?
Ryan Guina says
Adrienne, the Roth TSP hasn’t officially been released yet, so you can’t change it over while you are deployed. However, since you will be in a tax free zone, your contributions will be from tax exempt pay, which will automatically be tracked by the Thrift Savings Plan and your tax free TSP contributions will show up at the bottom of your statements. These tax free contributions are similar to the Roth, as they can be withdrawn without paying taxes when you are in retirement. However, it is only the contributions which can be withdrawn tax free, and not the earnings from those contributions.
After you separate from the military, you will be able to decide what to do with your TSP, including leaving it in the TSP, rolling it into a civilian TSP or a 401k plan, or rolling it into an IRA. If you choose to roll your TSP into an IRA, then you can leave your regular contributions in a Traditional IRA, and roll your tax-exempt contributions into a Roth IRA.
mikel says
Ryan i have a question can i contribute the whole 30,000 dollars (redux) to TSP ? without penalty with the IRS for tax purposes? let me know, because i am planning to get the redux and invest it to TSP .
Dan says
Ryan
Great website!
As the military rolls out the Roth TSP, can the $49,000 earned in a combat zone, be contributed to the ROTH TSP for each calendar year?
Thanks again!
stan68ar says
Mikel – TSP is limited to payroll deductions only so REDUX payment is a no go – IRA (up to annual limit) and rest in ROTH would seem a possible course to me.
JD says
Ryan,
Great info on the TSP…. Question regarding a military bonus…
I will shortly be receiving the USAF Pilot Bonus. I would like to make the most of the bonus, while also trying to minimize the tax against it. It’s a $25K bonus. I’ve thought of making a lump sum contribution to the TSP for the year with $17K of the $25K. Does that mean that only $8K will be taxable?
I appreciate your help and all the info you’ve provided on your blog.
JD
Ryan Guina says
JD, My understanding is that you can contribute up to $17,000 of your base pay to the TSP, but you can contribute up to a total of $50,000 (source) when you add other funds such as bonuses and retention pay (source).
Regarding contributing from retention pay and bonuses: You can also contribute from 1 to 100 percent of any incentive pay, special pay, or bonus pay — as long as you also elect to contribute from your basic pay. (This quote is directly from the TSP website (second source link above).
To contribute your retention bonus, you need to also contribute form your base pay. So I recommend setting that up ASAP, even if it is only 1%.
You can contribute the entire $25,000 to the TSP if you want, but you don’t have to.
As for taxes, the amount you contribute will generally be exempt from federal taxes, but you will still have to pay the FICA and Medicare taxes, which is usually around 8% or so (see note by Nords on this thread).
So you would pay FICA and Medicare on any contributions, but you would not pay any Federal taxes on those contributions.
Any funds you take now would be taxed at their normal rates (FICA, Medicare, and state / federal).
If you receive the bonus in a tax free zone, then your entire bonus may be tax exempt. This has very nice long term potential.
matt says
Can an eligible military member who is also eligible for a 401(k) through a second employer contribute and max out both (which happens to be the same limit of $17,500 + $5500 catch up) or does the max of the two combined need to not exceed the annual limit? Thank you!
Ryan Guina says
Matt, The TSP and 401k plans are under the same umbrella and share a max contribution limit. You can contribute up to $17,500 + $5,500 catch-up contributions across both accounts. Note: this only applies to your personal contributions. The max including all employer matching, bonus contributions, and other contributions is $51,000.
It’s a good idea to plan your contributions accordingly, so you don’t contribute too much. I would recommend starting with the plan that has a company or agency match if you have one, that way you get any free money available to you. Then contribute to the plan that offers the best available investments with the remaining funds.
Best of luck, and thanks for your service.
Nate says
Ryan,
Thank you for all your information. I have a basic question. I understand that you can contribute $51,000 in TSP while deployed and that $17,500 of that can be put into Roth. Here are my questions.
1. Does that mean that while deployed, I can $17,500 in Roth TSP and $33,500 in traditioanl TSP?
2. Will this $33,500 in TSP also reduce my taxable income ON TOP of the tax free salary during deployment.
3. When I return from deployment, if I contribute $51,000K while deployed, can I still contribute more to TSP. In other words, is $51K my total for the year, or is it $51K while deployed and then another $17500 when I get back?
Thanks a bunch and keep up the strong work!
Nate
Ryan Guina says
Hello Nate, Thanks for contacting me. Here are the answers to your questions:
(1) You can only contribute up to $17,500 of your own funds (salary) into the TSP per year. You can contribute to either the Roth or the Traditional, your choice. Any additional TSP contributions must come from the employer (in this case, the military). Since there is no employer match, the contributions would have to come from things such as special duty pay, reenlistment bonuses, and other special payments you might receive while deployed. These can only go up to the $51,000 limit for the tax year. All employer contributions are automatically classified as Traditional TSP contributions (there is no way to change this).
(2) No. Your pay is already tax free. You won’t be able to reduce your taxable income more by making Traditional TSP contributions. This is why contributing to the Roth TSP is such a great deal while deployed.
(3) As stated in the first answer, your max contribution of your own funds is $17,500. The $51,000 limit includes employer contributions. These are the annual maximums and cannot be exceeded.
If you wish to do further investing, I recommend opening a Roth IRA, then the Savings Deposit Program, followed by non-taxable investments. This article on investing while deployed should be helpful. Thanks for your service!
John says
Mikel – TSP is restricted to pay-roll reductions only so REDUX transaction is a no go – IRA (up to yearly limit) and relax in ROTH would seem a possible course to me. Thanks for sharing.
Ryan Guina says
Your comment is false, John. Military members who choose the Career Sates Bonus as part of the REDUX retirement plan are eligible to contribute 100% of the amount to the Thrift Savings Plan, provided they do not exceed the $52,000 annual contribution limit ($57,500 if over age 50). The annual contribution limit for payroll deductions is $17,500 ($23,000 if over age 50). However, TSP participants can contribute up to $52,000 ($57,500 if over age 50) if they elect to contribute eligible non-payroll compensation such as a reenlistment bonus, Career Status Bonus, or select other forms of income.
Here is more info: Career Status Bonus Options, and TSP Contribution Limits.
The idea of contributing to a Roth IRA is always a good one, however that does nothing to address the major tax hit a military member would take by choosing the REDUX option. Long term, the REDUX option is usually not the best long-term financial option unless there is an immediate and pressing need for the CSB. Even choosing to invest 100% of the CSB in the TSP isn’t a guaranteed method of beating the value of the higher pension that comes with the High-3 retirement plan. Most military members would be better off choosing the High-3 retirement plan, while continuing to make additional investments in their Thrift Savings Plan account, or in a Roth IRA.
Philip says
Is the amount that I can contribute to my TSP different if I am stationed in Puerto Rico?
Ryan Guina says
Philip, Thank you for contacting me. The amount you can contribute to your TSP should be the same regardless of where you are stationed.
Patrick Nelson says
Ryan, Good Morning.
So for 2015, can I contribute the max of $18K (non-combat pay) to my traditional military TSP, plus another $12K from special pay (Foreign Language Pay) for a total of $30K for the calendar year? Thank you.
Pat
Cody says
Ryan,
I’ve recently started active duty and I have about 10k sitting in my checking account I would like to put into a tsp account. Can I make this lump sum deposit from my checking account into a tsp account?
Ryan Guina says
Hi Cody, Unfortunately, you cannot make lump sum contributions to your TSP account. You can only make payroll deductions. However, you can increase your TSP contribution limit until you reach $10,000 and just live off your savings during that time frame. This will have the same long-term effect, but would require you to make the manual changes to your contributions as well as budget accordingly.
Chris says
I’m a reservist with civilian full-time employment. If I contribute $18,000 to my civilian employer’s 401-k program, can I still contribute to TSP?
Thanks!
Ryan Guina says
Hi Chris, the TSP shares a contribution limit with your civilian 401k plan. You can contribute to both, but you cannot exceed the annual limit of $18,000 (or the limit stated by the IRS).
Mike McKenna says
1. I now make 5% Roth only contributions to my TSP.
Is this good enough to receive the 5% matching, or do I need to make the 5% Traditional contributions too?
2. I want to contribute the full $18,000 in 2015 and this is November.
How exactly do I make the extra contribution to reach the maximum allowable – is there a form – do I call somebody – do I mail TSP a check?
Ryan Guina says
Hello Mike, Thank you for contacting me. To answer your questions 1) The government only offers matching contributions to civil service employees at this time. The new military retirement program will offer matching contributions for all servicemembers who opt into the new program, but that isn’t slated to start until 2018 (and many current military members will be better off under the current retirement system).
2). TSP contributions are payroll contributions, meaning they must come directly from your pay. You cannot contribute to the TSP in the form of a check. You can contribute almost the full amount of your paycheck, so you may wish to move your contribution amount to 100% of your paycheck for the final month of the year. Note that the December pay period is almost here, so you would need to get your new contribution amount set ASAP for it to take effect in time. I recommend planning your 2016 contributions now so you have a better chance of maxing out your TSP contributions in 2016.
K. C. says
“Catch-up contributions. Catch-up contributions are only available to those age 50 and above. To make catch-up contributions, you must first contribute the maximum amount of regular employee contributions, for the year, the elect to make catch-up contributions. Your catch-up contributions will stop automatically when you reach the contribution limit or at the end of the calendar year. You will need to elect to make catch-up contributions each calendar year.”
Unless this is different than contributions made by FERS employees, the statement above is not correct. You can make regular and catch-up contributions at the same time. You do not need to max out the regular contributions first. I have been doing this for years. This paragraph might better be stated like this.
“Catch-up contributions. Catch-up contributions are only available to those age 50 and above. To make catch-up contributions, you must elect to make catch-up contributions each calendar year. If you don’t they will automatically stop. You can made regular and catch-up contributions at the same time. If you plan the amounts you contribute carefully, you will maximize both the $18,000 regular contributions and the $6,000 in catch-up contributions during the last pay period of the year. This is much simpler than having to keep track of when your regular TSP contributions will max out, stopping the regular contributions, and then starting catch-up contributions.”
Ryan Guina says
Thank you for the clarification, K.C. The paragraph has been adjusted accordingly. Thanks!
Kevin says
Ryan,
I am a Retired Air Force Member and also a Federal Employee. I am expecting a significant amount of Veteran’s Administration Back Pay for Disabilities sustained while on Active Duty. Can I deposit those funds into my TSP when received?
Ryan Guina says
Hello Kevin, Thank you for contacting me. Unfortunately, you can’t contribute VA disability compensation pay into your TSP. Disability compensation is paid by the VA, not the military or the civil service. The TSP is a way to defer income from your job.
That said, Disability income is tax free, so you will receive the full amount. If you were planning on investing that money what you could do is put your disability compensation into your checking account and temporarily increase your TSP contributions to your desired level, then reduce your TSP contributions once you have deferred your desired amount of income. The effect will be similar, though it would take a little work on your end to coordinate. I hope this helps. Best of luck, and thank you for your service!
[email protected] MilitaryFIRE says
Great stuff- I’m finding a common misconception that service members cannot contribute to the TSP and and IRA. This misunderstanding seems especially prevalent with the Roth TSP. People seem to see “Roth” and think “IRA” with the $5500 contribution limit. The most common INCORRECT argument I hear is that you can contribute $5500 to your Roth IRA and $12500 to your Roth TSP!
The TSP’s website and the IRS do not do a good job explaining that you can save the max TSP contribution and contribute to an IRA simultaneously. As you note, the TSP is a deferral of income, whereas a (traditional) IRA deducts from income. These are important points, but they get glossed over because noone can conceive of saving much more that 10% of income, and especially not enough to need to use the TSP and an IRA.
Thomas says
Ryan:
Quick question, I miscalculated my deduction from Civil Service and ended up only contributing 17365.00 into my TSP and 5880.00 CUC. I’m an idiot.
Is there a way to top that out prior to April 15th in regards to the 2016 tax year. I have other accounts into which I could move the 635/120 dollars respectively if that helps to generate proof of contribution for the year. If unable, will that cause my CUC not to count for the year. And what sort of chocolate mess can I expect from CS pay/TSP.
Tony says
“Elective deferral contributions only apply to regular employee contributions that are made in before-tax (i.e., tax-deferred) dollars.”
I am a little confused in the language. For 2017 the Annual Contribution Limit is $18,000 and Annual Addition Limit is $54,000. Can I put $18,000 into my TSP and then put $36,000 into my ROTH TSP since the ROTH contributions are taxed?
Ryan Guina says
Hello Tony, Great question, and I should clear up that language. I believe it was written before the Roth TSP was around.
Unfortunately, that’s not how it works. You can only put in $18,000 from your salary, unless you are making contributions from a tax-exempt zone. The $54,000 annual addition limit accounts for agency matching or contributions from a tax-exempt zone. The agency match currently applies to civil service, but it will be part of the Blended Retirement System starting in 2018.
I hope that clarifies the process.
Tony says
Definitely clears it up, thanks for the quick reply.
Tom says
I contribute to my TSP to the max allowed and I have been missing out on the advantages of catchup elections. For the 2017 tax year, can I elect to contribute ($6K) of catch up contributions in the pay cycles in 2018 up April 15 for them to be counted towards the 2017 tax year and then revise my catch-up contribution for my remaining pay cycles in 2018 to max out the $6K for 2018?
Taylor says
I am currently Active Duty and are considering transitioning to a civilian career but staying in the Reserves. Can I only contribute to the TSP from my reserve pay? Or can I still contribute the max from my civilian pay?
Ryan Guina says
Taylor, you can contribute from your Reserve pay. You can also contribute to a civilian retirement plan, such as a 401k, 457, 403b, etc. However, the TSP and the civilian retirement plan share the same contribution limit. So for example, the contribution limit in 2018 is $18,500 for workers under age 50 (there is an additional $6,000 catch up contribution limit on top of that for those over age 50). You could contribute in any combination up to the limit. For example, $5,000 from Reserve pay and $13,500 from your civilian job, or any other combination not to exceed $18,500. The limit does not take into account agency matching contributions, so no need to calculate those.
You can no longer contribute to your military TSP from non-military income. You can only contribute via paycheck contributions. So you can continue contributing through the Guard or Reserves, but you cannot contribute to the TSP from civilian pay. You would need to contribute to a civilian retirement plan, or an Individual Retirement Account (IRA).
DLS says
I am doing to short term military deployment to a tax exclusion zone. I want to maximize my TSP contributions during this short time. I prefer the Roth option and would go 100% of all pay, if that were possible. In the past, when Roth TSP first became an option, my first contribution failed on my LES because the percentage was too high to cover federal withholding. The contribution election was allowed, but the TSP contribution was rejected on the subsequent LES. I don’t want to make this mistake now since my deployment is only four pay periods and I want to max the contributions.
The question is can BAH, which is not subject to fed withholding, but used to cover the withholding for my taxable income? Or do manage the percentage of my taxable pay, to leave enough to cover withholding?
Also, can traditional TSP contributions be rolled over to a Roth TSP in a later tax year?
Thanks.
Ryan Guina says
DLS, Thank you for your questions. To answer your questions – yes, the Roth TSP is the way to go when you are deployed. But as you learned, you can only contribute from your pay *after* your FICA and Medicare tax withholding (a total of 7.65&, combined). I believe the TSP will allow you to contribute up to 92% of your pay (with an 8% withholding to cover FICA and Medicare). That said, I would verify this number with the TSP, just to be certain. If you want to build a little margin into your withholding, you should be fine if you set it at 90%. That extra 2% won’t account for a large amount of money over 4 pay periods (2 months).
TSP Contributions can only be made from payroll deductions from your pay and certain bonuses, such as reenlistment bonuses. Likewise, your tax withholdings can also only com from your payroll. You cannot make TSP contributions from BAH, BAS, or other similar benefits, nor can those other benefits be used to cover tax withholdings.
The TSP does not allow Traditional to Roth conversions within the TSP. So any elections you make, either Traditional or Roth, are permanent until you decide to withdraw them or roll them out of the TSP (the only way to do that and maintain their tax benefits is to wait until you leave military service, at which point you can do an IRA rollover, or move it into a civilian TSP, 401k plan, or other tax advantaged account).

Mr Guina,
I have been withholding the standard 5% from my biweekly paychecks for my TSP (employer match 5%). I understand the maximum contribution to ANY retirement plan for calendar year 2017 is $18,000 for a single individual under 50 years of age. Is the TSP ROTH separate from a fidelity ROTH IRA? In other words, can i still contribute $5500 to a fidelity ROTH despite having ROTH TSP contributions for the year 2017?
Thank you for your time.

Hello Michael, The TSP and IRAs are separate accounts. You can contribute to the max in each account with them impacting each other. Best wishes!
