PERA contributions are not tax-deductible on your federal return. They receive a different and generally more valuable treatment: your employer excludes them from your taxable wages before your W-2 is issued, so the money never enters your gross income in the first place. There’s no line on Form 1040 to claim, because the benefit is already baked into Box 1. The trade-off is that every dollar you eventually receive as a pension payment is taxable when it lands.
Why PERA Contributions Are Deferred, Not Deducted
The federal rule sits in Section 414(h)(2) of the Internal Revenue Code. When a government employer “picks up” mandatory employee contributions to a retirement plan, those contributions are treated as employer contributions for tax purposes.1Office of the Law Revision Counsel. 26 USC 414 – Definitions and Special Rules The IRS has confirmed that picked-up amounts are excludable from gross income, so they bypass the federal income tax calculation entirely.2Internal Revenue Service. Employer Pick-Up Contributions to Benefit Plans
A deduction is something you subtract on your return after reporting the income. PERA works one step earlier. The income is never reported, so there’s nothing to deduct. Your W-2 Box 1 wages already reflect the reduction, and when you carry that figure to Form 1040, the tax deferral is built in automatically.3Internal Revenue Service.

For this treatment to apply, the contribution must be mandatory and the employee cannot have the option to take the money as cash instead. Nearly all PERA systems meet those requirements because participation is compulsory for eligible government workers. If you’re a standard PERA member, the pre-tax treatment happens automatically on every paycheck without any action from you.
What Taxes You Still Pay Now
Federal income tax and payroll taxes follow different rules, and the difference surprises people. Even though PERA contributions are excluded from your federal income tax base, they may still be subject to Social Security and Medicare (FICA) taxes depending on how your employer structures the payment.
The IRS distinguishes between true employer supplements and salary reductions. If your employer pays the contribution on top of your full salary with no offsetting pay reduction, the contribution isn’t included in FICA wages. If the contribution effectively reduces what you would otherwise be paid, it’s treated as a salary reduction and remains subject to Social Security and Medicare withholding.2Internal Revenue Service. Employer Pick-Up Contributions to Benefit Plans Most PERA systems operate through payroll withholding that functions as a salary reduction, so many members do pay FICA on their contributions.
Many state and local government employees covered by PERA don’t participate in Social Security at all. Whether your position is covered depends on agreements between your employer and the Social Security Administration. Your pay stub tells you the answer.
State Income Tax Varies
Federal pre-tax treatment is uniform across the country. State treatment is not. Many states use federal adjusted gross income as the starting point for state taxes, which carries the PERA exclusion straight through. Other states require you to add pension contributions back into state taxable income, so you pay state tax on those dollars in the year you earn them regardless of the federal exclusion.
The trade-off shows up later. If your state taxes PERA contributions now, you won’t owe state tax on the portion of your pension that represents those already-taxed contributions when you retire. If your state follows the federal approach and defers, your full pension check is subject to state income tax later. Check your state revenue agency’s instructions and note whether the return starts with federal AGI or requires a separate retirement contribution add-back.
How PERA Affects Your IRA Deduction
Here’s a downstream consequence worth planning around. Participating in any employer retirement plan, including a government pension, makes you an “active participant” in the eyes of the IRS. That status can limit or eliminate your ability to deduct Traditional IRA contributions.4Internal Revenue Service. IRA Deduction Limits
Whether you can deduct depends on your modified adjusted gross income (MAGI) and filing status. For 2026, the phase-out ranges are:5Internal Revenue Service. 401(k) Limit Increases to $24,500 for 2026, IRA Limit Increases to $7,500
- Single or head of household: $81,000 to $91,000. Full deduction below $81,000, no deduction above $91,000.
- Married filing jointly, PERA member: $129,000 to $149,000.
- Married filing jointly, only your spouse has a workplace plan: $242,000 to $252,000.
- Married filing separately: $0 to $10,000.
Inside the range, you get a partial deduction. Above it, the deduction disappears. You can still contribute to a Traditional IRA (the 2026 limit is $7,500), but you won’t get a tax break for doing so. For PERA members earning moderate government salaries, the single-filer threshold of $81,000 is within reach, which makes a Roth IRA (no upfront deduction, tax-free withdrawals later) often the better fit.
Your MAGI for IRA deduction purposes starts with your adjusted gross income and adds back items like the student loan interest deduction and foreign earned income exclusions.6Internal Revenue Service. Modified Adjusted Gross Income For most PERA members without foreign income or unusual deductions, MAGI runs very close to AGI.
What You’ll Owe When the Pension Starts
Tax deferral isn’t tax elimination. When you begin receiving pension payments, those payments are generally taxed as ordinary income at your federal rate for that year.7Internal Revenue Service. Publication 575 – Pension and Annuity Income If all of your contributions were made pre-tax, which is the case for most PERA members, every dollar of your monthly pension check is fully taxable.
One exception: if you made any after-tax contributions to the plan, those dollars are your cost basis and can be recovered tax-free over your retirement. The IRS requires most retirees from qualified plans to use the Simplified Method, which divides total after-tax contributions by a number of expected monthly payments based on your age at retirement, producing a fixed tax-free portion of each check.7Internal Revenue Service. Publication 575 – Pension and Annuity Income If your contributions were entirely pre-tax, this doesn’t apply.
A large pension combined with Social Security, IRA withdrawals, or other income can push you into a higher bracket than you’d planned for. Some retirees stagger income sources across years or make Roth conversions before pension payments begin to smooth out their lifetime tax burden.
Confirming It on Your W-2
Your W-2 does the work for you. Box 1 shows wages after mandatory pre-tax PERA contributions have already been subtracted, so transferring that number to Form 1040 carries the tax deferral through automatically.3Internal Revenue Service. Retirement Plan FAQs Regarding Contributions – Are Retirement Plan Contributions Subject to Withholding for FICA, Medicare or Federal Income Tax There’s no separate deduction to claim and no additional form to file.
For 2026, the IRS has split the old Box 14 into Box 14a and Box 14b. Your PERA contributions appear in Box 14a, typically labeled with a code like “PERA” or “RET.”8Internal Revenue Service. 2026 General Instructions for Forms W-2 and W-3 That figure is informational. It tells you how much was withheld for retirement but doesn’t change your tax calculation, and it’s useful for verifying your employer reported everything correctly.
Check Box 13 too. The “Retirement plan” box should be marked if you’re an active PERA member, and that mark is what triggers the IRA deduction phase-out rules above. If it’s checked incorrectly or missing when it should be there, your IRA deduction eligibility can be affected. Compare your final pay stub of the year against the W-2 to catch any discrepancy, and ask your payroll department to correct anything that doesn’t match.
