Frequently Asked Questions
How does the TSP match work?
TSP offers a 5% match for FERS/BRS participants. Contribute 5% to get full match, maximizing retirement savings. Legacy retirement participants don't receive this match.
What are the TSP withdrawal options?
TSP allows rollovers to IRAs or new 401(k)s. Loans and in-service withdrawals are available for those 59½ or facing hardship. Consider tax implications before withdrawing.
Can I access mutual funds in TSP?
Yes, TSP's Mutual Fund Window provides access to thousands of funds for added diversification. Additional fees apply, so evaluate costs versus benefits.
The Bottom Line Up Front
The Thrift Savings Plan is the cheapest retirement account most service members will ever have access to. With an expense ratio around 0.055% and a guaranteed 5% employer match for FERS-eligible participants, there is no excuse to leave this benefit on the table. The 2026 elective deferral limit is $23,500 ($31,000 with catch-up), and combat zone pay contributed to a Roth TSP grows completely tax-free.
Your approval for a VA home loan depends on credit, income, and assets. The TSP directly strengthens your asset position, and consistent contributions demonstrate financial stability that helps during mortgage qualification. Understanding the TSP is not just about retirement planning; it also affects how strong your financial profile looks when you are ready to buy a home.
Key TSP Numbers for 2026
- Elective deferral limit: $23,500
- Catch-up contribution (age 50+): $7,500
- Annual additions limit (employer + employee): $70,000
- Expense ratio: ~0.055%
- FERS automatic contribution: 1% of base pay (no employee contribution required)
- Full FERS match: 5% of base pay triggers maximum employer contribution
How The FERS Match Works
The match is the highest guaranteed return you will find in any investment. For every dollar you contribute up to 3% of base pay, the government matches dollar for dollar. The next 2% gets matched at 50 cents per dollar. If you are contributing less than 5%, you are forfeiting part of your compensation.
Service members transitioning to civilian federal employment keep their TSP accounts and begin receiving the FERS match immediately if they are under the FERS retirement system. Those who stay uniformed and are covered under the Blended Retirement System (BRS) also receive matching contributions. Legacy (High-3) retirement participants do not get a match.
| Your Contribution | Government Match | Total Going Into TSP |
|---|---|---|
| 0% | 1% (automatic) | 1% |
| 1% | 1% auto + 1% match = 2% | 3% |
| 3% | 1% auto + 3% match = 4% | 7% |
| 5% | 1% auto + 4% match = 5% | 10% |
At 5% contribution, you are getting a 100% return on your first 3% and a 50% return on the next 2% before the funds even invest in a single stock or bond. If you are managing a budget on military pay, start at 5% and work up from there.
Deal Saver
If you are planning to buy a home in the next 12 months, your TSP balance counts as verified assets on a mortgage application. Consistent TSP contributions also show the underwriting system that you handle money responsibly, which helps when AUS evaluates your file.
TSP Fund Options Explained
The TSP gives you five individual funds and a set of Lifecycle (L) Funds that blend them automatically. The single biggest mistake service members make is leaving everything in the G Fund, which protects principal but barely keeps pace with inflation.
| Fund | What It Tracks | Risk Level | 10-Year Avg. Return |
|---|---|---|---|
| G Fund | Government securities | Lowest | ~2.5% |
| F Fund | Bloomberg U.S. Aggregate Bond Index | Low-Moderate | ~1.5% |
| C Fund | S&P 500 | Moderate-High | ~12% |
| S Fund | Dow Jones U.S. Completion Total Stock Market | High | ~9% |
| I Fund | MSCI EAFE Index (international) | High | ~5% |
Lifecycle Funds are target-date blends. The L 2065 Fund is heavily weighted toward C, S, and I (higher growth, higher risk). The L Income Fund is almost entirely G and F (capital preservation). If you do not want to manage allocations yourself, pick the L Fund closest to your expected retirement year and let it auto-rebalance.
For service members under 40 with a long time horizon, a common allocation is 60% C Fund, 20% S Fund, and 20% I Fund. This mirrors a total world stock market approach with an expense ratio 20 to 40 times cheaper than a typical mutual fund.
Roth TSP vs. Traditional TSP
This decision comes down to when you want to pay taxes. Traditional contributions reduce your taxable income now and get taxed at withdrawal. Roth contributions are made after tax, but qualified withdrawals in retirement are completely tax-free.
For most junior and mid-grade service members, Roth is the stronger play. Military base pay puts you in a lower federal bracket, especially with BAH and BAS excluded from federal income tax. If you are managing your finances after military transition, locking in today’s lower tax rate through Roth contributions protects you against future rate increases.
| Feature | Traditional TSP | Roth TSP |
|---|---|---|
| Tax on contributions | Pre-tax (reduces current taxable income) | After-tax (no current deduction) |
| Tax on withdrawals | Fully taxable as ordinary income | Tax-free if qualified |
| RMDs at age 73 | Yes | No (after rollover to Roth IRA) |
| Combat zone advantage | Tax-free going in, taxed coming out | Tax-free going in, tax-free coming out |
| Best for | High earners near retirement | Younger service members in lower brackets |
Deal Math
Combat zone pay contributed to a Roth TSP is never taxed at any point: not when earned, not when contributed, and not when withdrawn. An E-5 deploying for 12 months who maxes Roth TSP contributions during that period builds a tax-free asset that compounds for 20+ years.
TSP vs. IRA: When You Need Both
The TSP and an IRA are not competing tools. They solve different problems, and most service members benefit from having both. The TSP wins on fees and match; the IRA wins on investment flexibility and withdrawal options.
The 2026 IRA contribution limit is $7,000 ($8,000 with catch-up for age 50+). If you are already contributing 5% to TSP to get the full match, directing additional savings to a Roth IRA gives you access to individual stocks, real estate investment trusts, and sector ETFs that the TSP does not offer.
| Feature | TSP | IRA |
|---|---|---|
| 2026 contribution limit | $23,500 (+$7,500 catch-up) | $7,000 (+$1,000 catch-up) |
| Employer match | Up to 5% under BRS/FERS | None (except SEP/SIMPLE) |
| Expense ratio | ~0.055% | 0.03% to 1.5%+ depending on provider |
| Investment options | 5 funds + L Funds | Stocks, bonds, ETFs, REITs, mutual funds |
| Withdrawal flexibility | Limited (monthly/quarterly/annual) | Any amount after 59½ |
| Loan availability | General purpose and residential loans | No loans |
Priority order: contribute 5% to TSP first (free match), then max a Roth IRA ($7,000), then go back and increase TSP contributions toward the $23,500 cap. This sequence maximizes both employer match and investment diversity.
Managing Your TSP During Military Transitions
PCS moves, deployments, and separation create decision points for your TSP. The good news is that the account travels with you regardless of duty station, branch, or civilian employer.
During deployment to a combat zone, your pay is tax-exempt. Contributing that pay to a Roth TSP is one of the most powerful wealth-building moves available to military members. Even if your deployment is only 6 months, the tax-free contributions compound for decades.
TSP Moves at Separation
- Leave the balance in TSP: keeps the ultra-low expense ratio; you can still make interfund transfers
- Roll to a Roth IRA: eliminates future RMDs and opens full investment menu
- Roll to new employer 401(k): consolidates accounts but may have higher fees
- Withdraw: taxable event plus 10% penalty if under 59½ (waived if separated at 55+)
If you are separating and planning to use your VA Certificate of Eligibility to buy a home, do not cash out your TSP for the down payment. VA loans require zero down in most cases. Keeping your TSP intact preserves your retirement trajectory and strengthens your verified asset position on the loan application.
How TSP Affects Your VA Loan Application
Lenders look at your complete financial picture when your file runs through automated underwriting. A healthy TSP balance signals financial discipline and provides verified reserves if AUS conditions them.
TSP balances count as assets on your mortgage application. While VA loans do not routinely require reserves, a strong asset position can offset a borderline debt-to-income ratio or lower credit score. If your DTI is approaching 50% or your credit is in the mid-600s, having 3 to 6 months of mortgage payments in your TSP can be the difference between an approve and a refer.
The VA funding fee on a first-use purchase with zero down is 2.15% of the loan amount. With a 5% down payment, it drops to 1.50%, and at 10% or more down, it drops further to 1.25%. Service members with a VA disability rating are exempt from the funding fee entirely. None of these costs require you to liquidate retirement funds; the funding fee can be rolled into the loan balance.
Approval Watchpoint
Do not take a TSP loan to cover closing costs on a VA purchase. The loan repayment adds a monthly obligation that increases your DTI, and if you separate before repaying it, the outstanding balance becomes taxable income plus a 10% early withdrawal penalty if you are under 59½.
Common TSP Mistakes That Cost Service Members Money
The three most expensive TSP mistakes happen early in a military career when compounding has the most time to work.
The first is contributing less than 5%. Every dollar below that threshold is employer match left on the table. On an E-6 base pay of roughly $3,600 per month, skipping the match costs about $2,160 per year in free money.
The second is staying in the G Fund. New accounts default to an age-appropriate L Fund, but some service members switch to 100% G Fund for safety. Over a 20-year career, the difference between G Fund returns (~2.5%) and a diversified C/S/I blend (~10%) on $500 per month in contributions is hundreds of thousands of dollars.
The third is cashing out at separation. A $40,000 TSP balance cashed out at age 30 triggers roughly $10,000 in federal taxes and penalties. Left invested at an 8% average return, that $40,000 becomes approximately $435,000 by age 65.
Costly Mistakes to Avoid
- Contributing below 5% and missing the employer match
- Parking everything in the G Fund for decades
- Cashing out at separation instead of rolling over
- Taking a TSP loan right before buying a home (increases DTI)
- Ignoring Roth contributions during combat deployments
- Failing to update beneficiary designations after marriage or divorce
Withdrawal Strategies In Retirement
How you take money out of the TSP matters as much as how you put it in. The wrong withdrawal sequence can push you into a higher tax bracket or trigger unnecessary penalties.
Traditional TSP withdrawals are taxed as ordinary income. If you have both Traditional and Roth balances, the TSP processes withdrawals proportionally from each unless you specify otherwise. Required minimum distributions begin at age 73 for Traditional balances. Roth TSP balances are subject to RMDs unless you roll them into a Roth IRA, which has no RMD requirement.
For service members who manage their family finances on biweekly pay, planning withdrawals years in advance lets you model tax liability and avoid surprises. The installment option lets you set monthly, quarterly, or annual payments, and you can adjust the amount once per year.
Tax-Smart Withdrawal Sequence
- Use taxable accounts first (brokerage, savings) to let tax-advantaged accounts keep growing
- Draw from Traditional TSP in years when your income is low to fill lower brackets
- Convert Traditional TSP to Roth IRA in low-income years before RMDs start
- Use Roth funds last, allowing maximum tax-free compounding
- Roll Roth TSP to Roth IRA to eliminate RMD requirements
TSP Loans: When They Make Sense
The TSP offers two loan types: general purpose (repaid within 1 to 5 years) and residential (repaid within 1 to 15 years, for primary residence purchase). The interest rate is the G Fund return rate at the time of the loan.
TSP loans are not free money. The amount you borrow stops earning market returns, and if you separate from service with an outstanding loan balance, you have 90 days to repay or the balance is treated as a taxable distribution. For home purchases, a VA loan with zero down payment almost always makes more sense than borrowing against your own retirement to fund a conventional purchase. VA loans carry no private mortgage insurance, which saves you additional monthly cost.
File Guidance
If you are considering a TSP residential loan for a home purchase, talk to a VA-experienced lender first. The VA’s zero-down benefit and competitive rates usually beat any TSP loan structure, and you keep your retirement assets invested.
Check Your VA Loan Eligibility
The Bottom Line
The TSP is the most cost-efficient retirement tool available to service members and federal employees. Contribute at least 5% to capture the full match, choose age-appropriate fund allocations, and use Roth contributions when your tax bracket is low. When you are ready to buy a home, your TSP balance strengthens your mortgage file without needing to liquidate it.
Pair your TSP strategy with your VA loan pre-approval process. The financial discipline that builds a strong TSP account is the same discipline that produces clean mortgage files. Your VA loan income requirements focus on stable, verifiable income, and your TSP demonstrates that you manage what you earn.
Frequently Asked Questions
What is the 2026 TSP contribution limit?
The 2026 elective deferral limit is $23,500. Participants aged 50 and older can contribute an additional $7,500 in catch-up contributions, for a total of $31,000. The annual additions limit (employee plus employer contributions) is $70,000.
Can I change my TSP fund allocations at any time?
Yes. You can make interfund transfers through the TSP website or app at any time. Interfund transfers move your existing balance between funds. You can also change your contribution allocation, which determines where future contributions go, without affecting existing balances.
Does my TSP balance help me qualify for a VA loan?
Your TSP balance counts as verified assets on a mortgage application. While VA loans do not routinely require reserves, a solid asset position can help offset a higher DTI ratio or lower credit score when your file runs through automated underwriting.
Should I cash out my TSP to make a down payment on a home?
No. VA loans allow zero down payment on most purchases. Cashing out your TSP triggers income tax on the full amount plus a 10% early withdrawal penalty if you are under 59 and a half. Keep your TSP intact and use the VA benefit as designed.
Is combat zone pay contributed to Roth TSP really tax-free forever?
Yes. Combat zone pay is excluded from federal income tax. When you contribute it to a Roth TSP, it goes in tax-free and comes out tax-free in retirement as long as the withdrawal is qualified (age 59 and a half and account open 5+ years). This is one of the most powerful tax advantages available to military members.
What happens to my TSP if I leave the military?
Your account remains with TSP. You can leave it invested, roll it into an IRA or new employer plan, or begin withdrawals. The ultra-low expense ratio makes TSP worth keeping open even after separation. You lose the ability to make new contributions through payroll deduction but can still make interfund transfers and manage allocations.
Can I borrow from my TSP to buy a home?
The TSP offers a residential loan repaid over 1 to 15 years at the G Fund rate. However, the loan amount stops earning market returns, and separating with an outstanding balance creates a taxable distribution. A VA loan with zero down payment is almost always the better option for home purchases.
