VSIP Buyout Rules: How the $25,000 Federal Separation Incentive Actually Works

What a VSIP Actually Is

A Voluntary Separation Incentive Payment is a one-time cash payment authorized under 5 CFR Part 576, designed to encourage federal employees to leave voluntarily during agency restructurings. It is not a retirement benefit, not a bonus, and not severance pay — though its calculation borrows from the severance formula.

Agencies request VSIP authority from OPM (or exercise standing authority, as the Department of Defense does), and eligible employees can accept the payment by separating within the designated window.

How the Payment Is Calculated

The VSIP amount equals the lesser of:

1. Your calculated severance pay — one week of basic pay for each of your first 10 years of civilian service, plus two weeks of basic pay for each year beyond 10, plus 25% of the applicable weekly amount for each full three months of creditable service beyond the final full year and an age-adjustment allowance of 2.5% of the basic allowance for each full three months of age over 40, subject to the 52-week lifetime limit
2. $25,000 (the statutory maximum for most agencies; $40,000 for DoD)

Most career employees with 15+ years of service and a GS-12 or higher salary will hit the $25,000 cap. The formula matters mainly for shorter-tenured or lower-graded employees.

Example: A GS-13, step 5 employee with 22 years of service earns roughly $115,000 in basic pay. Their severance calculation would yield approximately 34 weeks of pay — well above $25,000. So their VSIP is $25,000.

Tax Treatment

The VSIP is classified as supplemental wages and taxed accordingly:

• Federal income tax: 22% flat supplemental withholding rate
• State income tax: varies by state (some states exempt federal separation payments)
• FICA: Social Security (6.2%) and Medicare (1.45%) apply

On a $25,000 gross VSIP, expect federal withholding of $5,500, FICA of roughly $1,912, and state taxes on top. Net payment typically lands between $16,500 and $19,000 depending on your state.

The VSIP shows up on your W-2 as ordinary income. If you separate late in the year and your total income pushes you into a higher bracket, the 22% withholding may be insufficient — you could owe additional taxes when you file.

The Reemployment Repayment Trap

This is the most consequential rule most employees underestimate. Under OPM regulations, if you accept a VSIP and return to any compensated federal position within five years of your separation date, you must repay the entire gross amount — not the net you received, the full $25,000 — before your first day of reemployment.

"Compensated federal position" is interpreted broadly. It includes:

• Direct hire into any executive branch agency
• Personal services contracts
• Reemployment as a reemployed annuitant (if you also retired under VERA)

The only statutory exemptions that don't trigger repayment:

• Employment with the Government Accountability Office (GAO)
• Employment with the U.S. Postal Service
• Employment with the Postal Regulatory Commission
• A rare OPM waiver based on imminent threats to life or property

DoD adds its own layer: a mandatory 12-month ban on reemployment within the same department, even if you're willing to repay the buyout.

VSIP Without VERA

Taking a VSIP without also qualifying for VERA or standard retirement means you are resigning, not retiring. The practical consequences:

• No immediate annuity — you may qualify for a deferred retirement at age 62 with at least 5 years of civilian service
• FEHB coverage ends on separation — you get 31 days of free coverage, then can elect 18 months of Temporary Continuation of Coverage (TCC) at full cost plus a 2% administrative charge
• FEGLI terminates — you have 31 days to convert to an individual policy at commercial rates
• No FERS Supplement

For employees who don't meet VERA thresholds, the VSIP is essentially a $25,000 cash payment in exchange for losing your job, your health insurance, and your pension eligibility until age 62. Whether that trade makes sense depends entirely on your outside employment prospects and personal financial situation.

VSIP With VERA

When paired with VERA, the VSIP becomes a cash bridge during the period between your last paycheck and your first full annuity payment. OPM's processing timeline means you'll typically receive interim payments (60% to 80% of your estimated annuity) within 7 to 30 days if your application is submitted digitally through ORA, with final adjudication averaging 40 to 66 days.

The VSIP covers the gap — especially since interim payments don't include deductions for health insurance premiums, and any retroactive adjustments are settled once your case is finalized.
