Former Spouse Federal Pension Taxes: How Your Annuity Share Is Taxed

Every dollar you receive from your former spouse's federal pension is taxable income to you — not to your ex-spouse. OPM handles the reporting, but you are responsible for managing withholding and filing.

How OPM Reports Your Income

OPM issues a separate Form 1099-R directly to you each year for the annuity apportionment you received. The retiree gets their own 1099-R showing only their retained share. Your portions are tracked independently — the retiree does not report your payments and cannot deduct them.

Under current tax law, annuity apportionments paid under a COAP are not deductible by the retiree as alimony. The payments are treated as a court-ordered division of property, not spousal support.

Tax Withholding on Your Share

OPM applies mandatory federal income tax withholding to your monthly apportionment. You can adjust your withholding rate by filing Form W-4P through OPM Services Online or by mailing it to OPM.

If you live in a state with income tax, you may also owe state tax on your federal pension share. OPM does not withhold state taxes automatically in most cases — check whether your state requires separate withholding arrangements or estimated payments.

TSP Distributions: Rollover or Pay the Tax

If your court order divided the Thrift Savings Plan, the tax treatment depends on how you receive the funds:

Direct rollover to an IRA or employer plan. A direct rollover of pre-tax TSP funds to a Traditional IRA or eligible employer plan generally defers income tax. A rollover of pre-tax funds to a Roth IRA is a taxable conversion; Roth TSP funds follow separate tax rules. You generally pay tax on pre-tax funds when you withdraw them later.

Cash distribution. The taxable portion is generally ordinary income in the year you receive it. The TSP generally withholds 20% from an eligible rollover distribution paid directly to you. However, distributions under a qualifying court order are exempt from the 10% early withdrawal penalty under IRC Section 72(t)(2)(C), even if you are under 59½.

If the TSP pays an eligible rollover distribution to you by check instead of making a direct rollover, you generally have 60 days to deposit the full gross amount (including the 20% that was withheld) into an eligible plan or IRA to defer tax on the taxable portion. You would then claim the withheld amount when you file your tax return.

FERS Basic Employee Death Benefit (BEDB)

If your former spouse died while still an active federal employee and you were awarded the Basic Employee Death Benefit, this payment is also taxable income. As of 2026, the BEDB equals 50% of the employee's final salary (or high-three average pay, if higher) plus $43,800.53.

You can receive the BEDB as a lump sum or in 36 monthly installments. The lump sum is eligible for direct rollover into an IRA, which defers the tax. Monthly installments are taxed as ordinary income in each year received.

Survivor Annuity Tax Treatment

A former spouse survivor annuity is taxed under the federal rules for CSRS or FERS survivor annuities. OPM issues you a Form 1099-R, and the payment may be fully or partly taxable; a tax-free recovery of the retiree's contributions can reduce the taxable portion.

Practical Steps

Set your withholding rate to match your overall tax bracket, not the default OPM rate. Former spouses who also work or receive Social Security may need higher withholding or quarterly estimated payments to avoid an underpayment penalty at tax time.
