Dividing the Thrift Savings Plan (TSP) in Military Divorce — Complete Guide

How TSP Is Divided in Divorce

The Thrift Savings Plan (TSP) is the federal government's defined contribution retirement plan for federal employees and uniformed services members. Dividing a TSP account in divorce requires a specific court order called a Retirement Benefits Court Order (RBCO).

What Is an RBCO?

A Retirement Benefits Court Order (RBCO) is the legal document that authorizes the TSP to divide an account pursuant to a divorce decree. Formerly called a "TSP court order," the RBCO replaced the older terminology.

Key points

• A divorce decree alone is not sufficient — the TSP requires a specific RBCO.
• The RBCO must meet specific TSP requirements.
• The TSP reviews the order for compliance before processing.

Traditional vs. Roth TSP

TSP accounts can be either Traditional (pre-tax) or Roth (after-tax). The division rules differ:

Traditional TSP

• Divided as pre-tax funds
• Transfer to a traditional IRA for the former spouse is tax-free at transfer
• Taxes are due upon withdrawal

Roth TSP

• Divided as after-tax funds
• Transfer to a Roth IRA is tax-free
• Qualified withdrawals are tax-free in retirement

If both types exist

The RBCO should specify how to divide each portion. If unspecified, the TSP will divide pro-rata across both.

Tax Treatment of TSP Transfers

Tax-free transfers under IRC §414(h) and QDRO rules

A transfer to a former spouse's IRA is not a taxable event. The former spouse becomes responsible for taxes upon withdrawal.

If the former spouse takes cash instead

A direct cash payment from the TSP to the former spouse is:

• Subject to 20% federal income tax withholding
• Potentially subject to a 10% early withdrawal penalty if the former spouse is under age 59½
• Reported as income

Recommended approach

Always transfer to an IRA ("trustee-to-trustee transfer") to avoid taxes and penalties.

TSP Loans and Divorce

If the service member has an outstanding TSP loan, it affects the division:

• The loan balance is deducted from the divisible amount.
• The outstanding loan may be called due if the account is fully distributed.
• The court order should address whether the loan is the service member's responsibility or shared.

---

Withdrawal Rules After Division

Once the TSP is divided, the former spouse's portion is in their own IRA or TSP account. Withdrawal rules then apply normally:

• Age 59½ — Penalty-free withdrawals
• Age 55 — If separated from service (Rule of 55, traditional TSP only)
• RMDs — Required Minimum Distributions at age 73 (or 75 for those born after 1960)
• Roth TSP — Qualified distributions are tax-free after age 59½ and 5-year holding period

TSP Division Example

Scenario: A federal employee has a $300,000 traditional TSP balance. The couple was married for 15 years, during which the employee contributed to TSP for 12 years.

Time-rule calculation

Former spouse's share = × 50% = 60% of total TSP balance

Actual division

Former spouse receives: $300,000 × 60% = $180,000 transferred to their traditional IRA Employee retains: $120,000 in TSP

Common Mistakes to Avoid

1. Using a standard QDRO instead of an RBCO — TSP requires a specific RBCO, not a private-sector QDRO.
2. Not specifying traditional vs. Roth — Vague orders lead to pro-rata division that may not match intent.
3. Ignoring loans — An outstanding loan reduces the divisible balance and can cause issues.
4. Cash payments instead of transfers — Triggers taxes and penalties.
5. Forgetting tax basis — Roth TSP has already-taxed contributions; traditional does not.

Frequently Asked Questions

Can I just split my TSP without a court order?

No. The TSP requires a specific Retirement Benefits Court Order (RBCO) to divide an account.

Is a TSP transfer taxable?

A direct transfer to an IRA is tax-free. A cash distribution is taxable and may incur a 10% penalty.

What if I have both traditional and Roth TSP balances?

The RBCO should specify how to divide each. If unspecified, the TSP divides pro-rata.

Does my spouse get my TSP if I die?

TSP accounts pass to the designated beneficiary. Update your beneficiary after divorce — divorce does not automatically remove a spouse as beneficiary.
