How to Roll Over to TSP: A Complete Guide

What Does It Mean to Roll Over to TSP?

Rolling over to TSP means transferring funds from an eligible retirement account into your Thrift Savings Plan. The TSP is a tax-advantaged retirement savings program for federal employees and members of the uniformed services, and it also accepts rollovers from other qualified plans. A rollover is not a new contribution; it is a direct movement of existing retirement assets into your TSP account, typically to consolidate accounts, simplify management, or preserve the tax-deferred status of the funds.

Not every retirement account can be rolled into the TSP, and the rules differ depending on the source account and whether you are an active federal employee, a separated annuitant, or a military retiree. The following sections walk through the key types of rollovers, eligibility, and the step-by-step process.

Eligibility: Who Can Roll Over to TSP?

Eligibility depends on your status and the type of account you are rolling over.

• Active Federal Employees: You can roll over funds from a previous employer's 401(k), 403(b), or traditional IRA into your TSP. You do not need to have a current TSP balance to initiate a rollover.
• Separated Federal Employees and Annuitants: Former employees who left service can continue to manage and receive rollovers into their existing TSP accounts, though you cannot make new elective contributions after separation unless you are re-hired.
• Military Service Members: Active duty and reserve members can roll over eligible retirement funds into the TSP, and the rules are generally the same as for civilian federal employees.
• Non-Federal Employees: In most cases, the TSP does not accept rollovers from private-sector retirement plans unless you have a prior federal service history and an existing TSP account.

Types of Accounts Eligible for Rollover

The TSP accepts rollovers from specific types of tax-qualified and tax-deferred accounts. Understanding which accounts qualify helps prevent rejected transfers.

• Traditional 401(k) and 403(b): The most common rollover sources. Funds must come from a pre-tax or traditional (non-Roth) account.
• Traditional IRA: Direct rollovers from a traditional IRA are permitted. Roth IRA conversions generally cannot be rolled into the TSP.
• Federal Thrift Savings Plan Loans and Withdrawals: These are not rollovers; they are internal TSP transactions and follow different rules.
• Government 457(b) Plans: Rollovers from certain governmental 457(b) plans are allowed.
• Ineligible Accounts: Roth 401(k), Roth 403(b), and Roth IRAs are not eligible for rollover into the TSP.rollover to tsp from these accounts will be rejected.

Step-by-Step: How to Roll Over to TSP

Common Mistakes to Avoid When Rolling Over to TSP

• Taking a Check Instead of a Direct Transfer: If the distribution is made payable to you, 20% mandatory withholding may apply, and you will have 60 days to redeposit the full amount to avoid taxes and penalties.
• Rolling Over a Roth Account: The TSP does not accept Roth rollovers. Attempting this results in a rejected transfer and potential tax consequences.
• Missing the 60-Day Rule: Indirect rollovers have a strict 60-day deadline. Failure to complete the rollover on time triggers taxes and possibly a 10% early withdrawal penalty.
• Exceeding Contribution Limits: Rollovers do not count toward annual TSP contribution limits, but new contributions do. Do not confuse the two.

Tax Implications of a TSP Rollover

A rollover from a traditional qualified plan or traditional IRA to the TSP is generally tax-free at the time of transfer because the funds were already taxed or tax-deferred. The rollover preserves the tax-deferred status; you will pay income tax when you withdraw the funds in retirement. There is no 10% early withdrawal penalty solely for rolling over, but if you are under age 59½ and take a distribution instead of a direct rollover, taxes and penalties may apply.

Alternatives to Rolling Over to TSP

If you are not eligible for a TSP rollover or prefer not to use the TSP, consider these alternatives:

• Leave the funds in your former employer's plan, if allowed.
• Roll over to a new employer's 401(k) or 403(b) plan.
• Consolidate into a traditional IRA, which accepts a broader range of rollover sources.

Each option has different investment choices, fees, and withdrawal rules. Compare them before deciding.
