Mandatory Pension Contribution Paycheck Deduction Guide
Your mandatory pension contribution comes out of every paycheck. See 2026 rates by system, whether it lowers your taxes, and the FICA and state tax catches.

Your first public-sector paycheck arrives and there is a line on it you never signed up for. It might say 414H, RET, PERS, STRS, TRS, SERS, or FERS. For most public employees it lands somewhere between 3% and 14% of gross pay (some long-tenured federal employees pay under 1%), and no form in your onboarding packet let you choose it.
That is your mandatory pension contribution. Unlike a 401(k) or a 457(b), you did not pick the rate, you cannot lower it, and you cannot turn it off. It is a condition of employment written into statute or set by your plan’s actuary.
The rate is the easy part. What it does to your taxes is where people get lost, because federal income tax, FICA, and your state all treat it differently. Most explainers say “it’s pre-tax” and stop there. That shorthand is wrong often enough to cost people real money.
What a mandatory pension contribution actually is
You are in a defined benefit plan. It pays a lifetime benefit calculated from a formula (usually years of service times a multiplier times your final average salary), not from whatever your account happens to be worth on your last day of work.
Three streams fund that promise: your contributions, your employer’s contributions, and investment returns. Your share is smaller than it feels. Across public pension systems from 1992 through 2021, employee contributions supplied only about 11% of total revenue, according to NASRA. Investment earnings did most of the work.
The reason you cannot opt out is a tax rule, not an HR policy. Under IRC Section 414(h)(2), an employer can “pick up” employee contributions and exclude them from your federal taxable wages, but only if you have no choice in the matter. If you could elect out or take the cash instead, the exclusion disappears. The IRS requires the employer to take formal action specifying that the contributions are mandatory.
Worth clearing up, because most articles on this topic get it wrong: 414(h) is not a type of retirement plan. It is a tax treatment applied to a governmental Section 401(a) plan. Your plan is PERS or TRS or STRS. The 414(h) part only describes how the money is taxed on the way in.
Access to these plans is the main structural difference between public and private work. Roughly 86% of state and local government workers have access to a defined benefit pension and 75% participate, versus about 14% access in private industry, per BLS. The mandatory deduction is the price of admission.
How much comes out: 2026 contribution rates by system
Most public plans land between 4% and 8% of pay. The spread is wider than that suggests, and public safety plans usually run higher. Real member rates from the major systems, so you can find yourself:
| System | Who it covers | Member rate |
|---|---|---|
| CalSTRS (2% at 60, “Classic”) | CA teachers hired before 2013 | 10.25% |
| CalSTRS (2% at 62, PEPRA) | CA teachers hired 2013 or later | 10.205% |
| CalPERS school members (Classic) | CA school staff | 7.00% |
| CalPERS school members (PEPRA) | CA school staff hired 2013 or later | 8.00% |
| Texas TRS | TX educators | 8.25% |
| Illinois TRS | IL teachers | 9.0% (7.5% annuity + 0.5% AAI + 1.0% survivor) |
| STRS Ohio | OH teachers | 14% |
| NYSLRS Tier 6 | NY state and local | 3.00% to 6.00%, tiered by annual wage |
| FERS | Federal civilian hired before 2013 | 0.8% |
| FERS-RAE | Federal civilian hired in 2013 | 3.1% |
| FERS-FRAE | Federal civilian hired 2014 or later | 4.4% |
Rates change annually or biennially. Treat this table as a starting point and confirm your own number against your system’s contribution page.
NYSLRS Tier 6 deserves a special mention because it is the one common system where a raise can genuinely shrink your paycheck. Contribution rates step up by annual wage band, so crossing a threshold can move you from 4.5% to 5.75% on your entire salary. If your check went down after good news, that is a likely culprit, and we cover the other causes in why your paycheck went down after a raise.
Federal employees: you may have seen posts claiming all FERS employees move to 4.4% in 2026. That increase appeared in a House reconciliation markup in 2025 and was struck before final passage. It is not law. Your rate still depends on your hire date.
Does it lower your taxes? Three separate answers
This is where the “it’s pre-tax” shorthand falls apart. Three different taxes come out of your check, and your pension contribution treats each one differently.
| Tax | Does the pension contribution reduce it? |
|---|---|
| Federal income tax | Yes for most state and local plans (414(h) pick-up). No for federal FERS and CSRS. |
| Social Security and Medicare (FICA) | No, in nearly every case. |
| State income tax | Usually yes, but not in NJ, PA, or MA. |
Federal income tax: usually yes, unless you are a federal employee
If your employer picks up your contributions under Section 414(h)(2), the amount is excluded from W-2 Box 1. Your federal withholding drops accordingly, which means the deduction costs your take-home pay less than its face value.
Federal civilian employees are the exception, and it is a big one. FERS and CSRS retirement deductions come out of after-taxed wages. They stay in Box 1, they do not reduce your current federal income tax, and they become your cost basis in retirement (which is why retirees recover part of their annuity tax-free under the IRS Simplified Method).
So a state clerk and a federal clerk can have the same 4.4% line on the stub and completely opposite tax outcomes.
Social Security and Medicare: almost always no
More people get this wrong than anything else on the stub, and it throws off their budget math. A 414(h) pick-up funded by salary reduction is still Social Security and Medicare wages. The FICA exclusion requires a true salary supplement rather than a reduction, and essentially no plan is built that way.
The tell is on your W-2: Box 1 will be smaller than Box 3 and Box 5. That gap is your pension contribution. If you are Social Security covered, you still see the full 6.2% and 1.45% on every check. For the mechanics of those two lines, see FICA taxes explained, and for the box-by-box walkthrough, how to read your W-2.
State income tax: check your state
Most states follow the federal exclusion, so your pension contribution lowers state taxable wages too. A handful do not. Three of them come up constantly.
New Jersey, Pennsylvania, and Massachusetts still tax mandatory pension contributions at the state level. In those states the deduction is effectively pre-tax federally and post-tax for state purposes, and you may need to add the Box 14 amount back on your return. Massachusetts softens it slightly: you can deduct up to $2,000 per taxpayer for combined contributions to Social Security, Medicare, and US or Massachusetts retirement systems, but anything above that stays taxable. If you work in one of them, model your withholding on the New Jersey, Pennsylvania, or Massachusetts paycheck calculator rather than assuming the federal treatment carries over.
When your pension replaces Social Security
About 6.5 million state and local employees, roughly 28% of that workforce, are not covered by Social Security at all. Teachers in California, Texas, Ohio, Massachusetts, and several other states are the classic case. Their pay stub has no OASDI line on it, because the pension replaces Social Security instead of sitting on top of it.
If that is you, you still pay Medicare at 1.45% as long as you were hired after March 31, 1986. And the reason your pension rate looks brutal next to your friend’s in the private sector is that it is doing two jobs at once.
The same $70,000 salary, two ways.
| Covered worker (4% pension) | Non-covered worker (10.25% pension) | |
|---|---|---|
| Pension contribution | $2,800 | $7,175 |
| Social Security (6.2%) | $4,340 | $0 |
| Medicare (1.45%) | $1,015 | $1,015 |
| Combined annual total | $8,155 | $8,190 |
| Per biweekly paycheck | $313.65 | $315.00 |
The stubs look nothing alike. The totals differ by about a dollar and a half per paycheck. Before you conclude your employer is gouging you, check whether that 6.2% line exists.
One change most current employees missed: the Social Security Fairness Act, signed in January 2025, repealed the Windfall Elimination Provision and the Government Pension Offset. A public pension no longer reduces the Social Security benefit you earned in other jobs, or a spousal benefit. If you had written off your pre-teaching Social Security credits, revisit that.
Part-time, seasonal, and temporary public employees sometimes land in a different arrangement entirely: a Section 3121 FICA alternative plan. These require total contributions of at least 7.5% of pay standing in for Social Security, and in practice the employee usually funds the whole 7.5% with no employer match, taken pre-tax. Medicare at 1.45% still applies and the employer still matches that.
Do you get the money back if you quit?
Your own contributions are always yours. The employer’s share generally is not until you vest, which commonly takes five to ten years.
Most systems will refund your contributions after you separate. Before you ask for one, know what comes with it:
- It is taxable in the year you receive it, unless you roll it into an IRA or another eligible plan.
- The 10% early-distribution penalty may apply if you are under 59 and a half and do not roll it over.
- You usually forfeit the pension entirely. Taking the refund typically cancels your service credit, so you walk away from the employer-funded benefit, which is the larger half.
For a teacher four years into a five-year vesting schedule, that last one is often the whole decision.
Your pension is mandatory, your 457(b) is the part you control
The pension line is fixed. The other retirement line on many public-sector stubs is not. A governmental 457(b) is entirely your call: you set the deferral, change it whenever you want, and stop it if cash gets tight. It also behaves differently on the way out, with no 10% early-withdrawal penalty on distributions after you separate, at any age.
Worth understanding that contrast before you decide whether to save more. We walk through the deferral math, the pre-tax versus Roth split, and the 2026 limits in 457(b) deferred compensation and your paycheck.
Mandatory deductions outside government: state auto-IRAs
Private-sector workers are starting to see a deduction that looks a lot like this one. It is not the same thing. As of early 2026, 15 states run auto-IRA programs covering more than a million workers and holding over $2.5 billion.
The legal difference matters. Participation is mandatory for the employer, and enrollment is automatic for the employee, but you can opt out. That one fact separates it from a public pension, where opting out is not on the menu.
Default rates usually start around 3% to 5%. OregonSaves begins at 5% of gross pay and escalates 1% per year to 10%. Most programs are funded as Roth IRAs, so they come out of after-tax pay and do not lower your income tax. If you never touched the enrollment notice, that deduction is post-tax.
Modeling it in a paycheck calculator
Most calculators only give you generic pre-tax and post-tax deduction fields, so here is the practical translation.
Enter it as a pre-tax deduction if you are a state or local employee with a 414(h) pick-up and your state conforms to the federal treatment. Percentage-based entry is easier than dollars, since your rate is a percentage of gross.
Enter it as a post-tax deduction if you are FERS or CSRS, or if you live in New Jersey, Pennsylvania, or Massachusetts. In those cases the contribution does not reduce the taxable wages the calculator is working from. In a non-conforming state, the cleanest approach is to run it pre-tax to check your federal withholding, then post-tax to check your state withholding.
Adjust for Social Security if your job is not covered. A standard calculator will show a 6.2% OASDI line you do not actually pay, which overstates your withholding by hundreds of dollars a year. Subtract it yourself, or compare the OASDI figure against your real stub.
Pay44 handles the parts that matter here: percentage-based pre-tax and post-tax deduction fields, a per-pay-period breakdown, and state selection for all 50 states plus DC, so a New Jersey pick-up and a California one produce different answers instead of the same one. If you are weighing a public offer with a 9% mandatory pension against a private offer with an optional 401(k), the job offer comparator puts both on a net-pay basis, and the hourly paycheck calculator covers hourly and shift-based public roles. You can also download the app to run the numbers on your phone against your actual stub.
Two related reads if your stub still has unexplained lines: how to read your pay stub and pre-tax vs. post-tax deductions. Teachers on a 10-month schedule should also see teacher pay: 10 months vs. 12 months, since the pension percentage applies to each check regardless of how the year is spread.
All figures here are estimates for planning purposes. Confirm your contribution rate with your retirement system and your tax treatment with a tax professional.

Frequently Asked Questions
Can I opt out of a mandatory pension contribution?
No. For state and local plans using an IRC Section 414(h)(2) employer pick-up, the IRS requires that employees cannot elect out or take the money as cash, and that is what makes the contribution excludable from income. Membership is a condition of employment, and the rate is set by statute or the plan's actuary.
Does a mandatory pension contribution reduce my taxable income?
Usually, for state and local employees: a Section 414(h)(2) pick-up is excluded from federal taxable wages, so W-2 Box 1 is lower. Federal FERS and CSRS deductions are the exception, because they come out of after-tax pay and stay in Box 1. Your state may also disagree with the federal treatment.
Do pension contributions reduce Social Security and Medicare taxes?
No. When a pick-up is funded by salary reduction, which is how nearly every plan operates, the amount is still Social Security and Medicare wages. That is why W-2 Box 1 is smaller than Boxes 3 and 5. You will still see 6.2% and 1.45% on your stub if your job is Social Security covered.
What does 414(h) mean on my W-2?
It is your mandatory governmental pension contribution, reported in Box 14. The amount was already removed from Box 1 wages, so you do not deduct it again. New Jersey, Pennsylvania, and Massachusetts residents may need to add it back for state purposes, so check your state's instructions.
How much is a typical mandatory pension contribution?
Most public plans require between 4% and 8% of pay, though real rates run from about 3% (the low band of NYSLRS Tier 6) to 14% (STRS Ohio). Public safety rates are often higher. Federal FERS employees pay 0.8%, 3.1%, or 4.4% depending on hire date.
Why don't I see Social Security taken out of my paycheck?
About 6.5 million state and local employees, roughly 28% of the public workforce, are not covered by Social Security, because their pension plan serves as the substitute. You will still see Medicare at 1.45% if you were hired after March 31, 1986. Your pension deduction is generally larger to compensate.
Do I get my pension contributions back if I quit?
Your own contributions are always yours, and most systems let you request a refund after separation. But a refund is taxable in the year you receive it unless you roll it over, it may trigger a 10% early-distribution penalty, and it normally forfeits your right to the pension entirely, including the employer's share.
How is a mandatory pension different from a 401(k) or 457(b)?
A pension contribution is set by law and cannot be changed, while a 401(k) or 457(b) deferral is one you choose and can adjust any time. A pension pays a formula-based lifetime benefit; the others pay whatever your account is worth. Many public employees have both.
