What Is a Pension Buyback?
A pension buyback allows you to purchase additional years of credited service, typically from prior military service or other qualifying employment, and add them permanently to your pension. Purchased service is not always treated the same as FDNY service: what each bought year adds depends on your tier, so get the Fund's own statement before you decide. You pay a lump sum (or payroll deductions) today. Your pension pays more every month for the rest of your life.
A buyback adds to the pension you already have
Whether buying back time pays depends on the base it builds on. From 20 years on, the calculator works out your pension from your own service and salary. No sign-up to see it.

FDNY members may purchase credit for prior honorable active military service through the NYC Fire Department Pension Fund (NYCFPF). The most common qualifying service is time served in the U.S. Armed Forces before joining the FDNY, or military leave taken during your career.
General eligibility conditions:
- An honorable discharge qualifies. So do two paths a lot of members do not know about: state law (RSSL §1000) also covers a veteran with a qualifying condition, and a discharged LGBT veteran, in each case where the discharge was anything other than bad conduct or dishonorable. Both terms are defined in Executive Law §350. If your discharge was less than honorable, do not assume you are out. Ask the Fund.
- The buyback must be completed before your retirement date. You cannot purchase service after you separate
- Maximum purchasable credit is typically capped (verify the current limit with the FDNY Pension Fund directly)
- Members in both Tier 2 and Tier 3 may have buyback options, though the formulas and costs differ
Prior city service from another NYC agency may also be purchasable under separate provisions. The pension fund can tell you what qualifies for your specific situation.

The Math: How Much Does Your Pension Actually Increase?
This is the only number that matters. A pension buyback is a financial decision, not a sentimental one. The question is: how much does each purchased year add to your annual pension?
Your pension formula determines the answer. For FDNY Tier 2, the commonly cited benchmark is a pension worth approximately 50 percent of final average salary (FAS) at 20 years of service, the "half pay" rule most members know. Each additional year of service beyond that adds incrementally to the total.
When you buy back a year of prior service, you are effectively adding that year to your credited service total. For a member with a $110,000 final average salary, the pension impact of one additional credited year is a meaningful, permanent addition to lifetime income.
"Every year you purchase is a year you already served. You earned it. The question is whether it is worth paying for twice."
The FDNY Pension Fund will give you an official pension projection showing your estimated annual benefit with and without the purchased service. That difference, the annual pension increase, is the number you divide against your buyback cost.
The Break-Even Calculation
The break-even is simple arithmetic:
Break-Even Formula
Break-even years = Total buyback cost ÷ Annual pension increase from purchased service
Example: For military service, New York law sets the price at 3% of your last 12 months' pay per year bought if you joined before April 2012, or 6% if you joined after. On $120,000 of pay, two years cost $7,200 or $14,400. If those two years add $2,000 a year to your pension, break-even is about 3.6 years on the lower cost and 7.2 years on the higher one. The pension increase is the number to get from the Fund, since it depends on your tier.
Break-even benchmarks most members find useful:
| Break-Even | General Verdict | Why |
|---|---|---|
| Under 8 years | Strong case to buy | Most members easily outlive this threshold in retirement |
| 8 to 12 years | Good case for most | Average retirement spans 20+ years; still a strong net positive |
| 12 to 18 years | Health-dependent | Longevity and family history matter more at this range |
| Over 18 years | Scrutinize carefully | High cost relative to benefit; verify pension fund numbers |
These are general reference points, not personalized advice. Your actual numbers from the pension fund will determine where your buyback lands.
What the Buyback Costs and How Payment Works
For military service, the cost is set by Retirement and Social Security Law §1000, not by actuarial factors: 3% (joined before April 2012) or 6% (joined on or after) of your pay in the 12 months before you apply, for each year purchased. You need at least five years of credited service to apply, you can buy at most three years, and you must apply before you retire. Other kinds of prior service follow different rules, and the pension fund's cost statement is the authoritative number.
What members generally experience:
- For military service, each year costs 3% or 6% of your last 12 months' pay, which is a few thousand dollars a year for most members; other prior service can cost more
- Payment can often be made as a lump sum or through payroll deductions over a period of time
- Some members fund a lump-sum buyback from a 457(b). A cash distribution is taxable in the year you take it. A direct trustee-to-trustee transfer into the pension fund is not treated as a taxable distribution to you. The route you choose changes the tax, so model it before executing
- Interest accrues on unpaid balances if you choose installments, increasing the total cost
Request the official buyback cost statement early. Processing takes time, and the deadline is your retirement date.
The Tax Picture
Two facts that improve the buyback math for New York residents:
1. NY State does not tax FDNY pension income. The additional pension dollars from a buyback are exempt from New York State and City income tax. The benefit is larger in net terms than the gross number suggests.
2. You can often fund a buyback with pre-tax dollars. The old rule that buybacks are paid only with already-taxed money is not always true. FDNY members can move pre-tax dollars from the NYC Deferred Compensation Plan (Pre-Tax 457 or Pre-Tax 401(k)) straight into the pension fund as a direct trustee-to-trustee transfer. Done that way, the money is not treated as a taxable distribution to you. Whether payroll deductions come out pre-tax or after-tax depends on the plan. Either way, there is no separate income-tax deduction for the purchase itself. This gets technical fast, so confirm what the FDNY Pension Fund will accept and run the numbers with your tax professional before you move any money.
Federal tax still applies to FDNY pension income. Your pension increase will be partially offset by federal income tax, depending on your bracket in retirement.
The One Deadline That Catches Members Off Guard
The buyback must be completed before you retire. This sounds obvious, but in practice many members get caught. Here is what happens: a member decides to retire, submits paperwork, and then remembers they had military service they could have purchased. The window is closed.
If you have any qualifying prior service, start the inquiry with the FDNY Pension Fund at least 12 to 18 months before your target retirement date. The application, actuarial calculation, and payment processing all take time. Waiting until the final months of your career is a risk you do not need to take.

Is It Worth It? The Honest Verdict
For most FDNY members with qualifying military service and a break-even under 12 years: yes, the buyback is worth serious consideration. A pension is a lifetime annuity. The income it produces is guaranteed, inflation-adjusted in many formulas, and NY-exempt. Buying more of it at a reasonable cost is one of the few genuinely low-risk retirement decisions available.
Where members get into trouble is treating the buyback as automatic without running the numbers. A $50,000 buyback that adds $1,800 per year to a Tier 3 pension has a 27-year break-even. That changes the calculus entirely.
The steps that matter:
- Request the official buyback cost statement from the FDNY Pension Fund
- Get your pension projection with and without the purchased service
- Calculate your break-even and compare it to your realistic retirement horizon
- Decide how to fund the buyback (lump sum, payroll deductions, or 457(b) distribution; each has different tax consequences)
- Start at least 12 months before your retirement date
The 457(b) Connection
Some members fund a lump-sum buyback with a 457(b) distribution. This can work, but it is a taxable event in the year of withdrawal, and the timing affects your Roth conversion window. Model the tax cost of using 457(b) dollars versus paying from after-tax savings before deciding. The two decisions are linked.
