TSP Loans Before Military Separation: What Happens When You Leave

TSP loans are one of the most misunderstood aspects of military retirement savings. Many service members take TSP loans without knowing what happens to them at separation — and the consequences of not handling the loan correctly can cost thousands in taxes and penalties.

TSP Loan Basics

The TSP offers two types of loans:

• General Purpose Loan — Any purpose, repaid over 1–5 years
• Residential Loan — For purchasing a primary residence, repaid over 1–15 years

Loans can be up to 50% of your vested account balance, with a minimum of $1,000 and a maximum of $50,000. You repay through payroll deduction, and the interest rate is the G Fund rate at the time of the loan.

What Happens to Your TSP Loan at Separation

When you separate from the military, your payroll deductions stop. The TSP no longer has a mechanism to collect your monthly loan payments.

After separation, you have 90 days from your separation date to repay the outstanding loan balance in full. This is set by TSP rules (5 CFR Part 1655).

If you repay within 90 days: the loan closes cleanly, and your TSP account balance reflects the repaid amount. No tax consequences.

If you do NOT repay within 90 days: the unpaid balance is treated as a taxable distribution — the TSP reports it as income on a 1099-R, and the IRS taxes it accordingly.

The Tax Consequences of a Deemed Distribution

If your loan balance becomes a taxable distribution:

1. Federal income tax on the full unpaid balance at your marginal rate
2. 10% early withdrawal penalty if you're under 59½ (with some exceptions)
3. State income tax in most states

Example: You have $20,000 outstanding on a TSP loan when you separate at age 32. You don't repay it within 90 days. In the 22% federal bracket:

• Federal tax: $4,400
• 10% penalty: $2,000
• State tax (varies): ~$1,000
• Total lost to taxes/penalties: ~$7,400

You still owe nothing more to the TSP — the loan is closed and treated as a distribution. But you've effectively lost over a third of the loan balance to taxes.

The Partial Repayment Problem

The 90-day window is for full repayment. Partial repayments are accepted, but any remaining balance after 90 days is still treated as a distribution on the unpaid portion.

If you have $20,000 outstanding and repay $15,000 within 90 days, the remaining $5,000 becomes a taxable distribution.

Exception: If You Become a Federal Civilian Employee

If you leave the military and immediately (or within a short window) become a federal civilian employee, your TSP account can remain active. Loan repayments can continue through your new federal payroll.

This applies to FERS employees — those who leave the military and enter federal civilian service. In this case, the 90-day rule may not trigger. Confirm with TSP directly if this applies to your situation.

What to Do If You Can't Repay Before Separation

Options if a full repayment isn't feasible:

Rollover the loan amount from another account. If you have savings, an IRA, or other liquid funds, you can repay the TSP loan from those funds within 90 days. This avoids the tax consequences even if it temporarily depletes another account.

Reduce the loan balance before separation. If you're 6–12 months from separation, you can make additional TSP loan payments above your scheduled amount to reduce the balance.

Accept the tax consequence if the amount is small. If your outstanding loan balance is $3,000–$5,000 and you're otherwise in good financial shape, the math on the tax hit may be less damaging than using all your liquid savings for repayment.

Consult a tax professional. For large loan balances, the decision has significant financial implications. A CPA or enrolled agent who understands military transition finances can model the options.

Checking Your TSP Loan Balance

Log in to tsp.gov to see your current loan balance, repayment schedule, and the date your loan is scheduled to be paid off. If you're within 12 months of separation, know this number.
