How Does the Wisconsin Teachers Pension Work?

The Wisconsin teachers’ pension is a defined benefit plan run through the Wisconsin Retirement System (WRS) and administered by the Department of Employee Trust Funds (ETF). If you teach in a Wisconsin public school, you and your employer together pay 16.0% of your salary into the system in 2026, and when you retire you receive a lifetime monthly annuity calculated two different ways, with ETF paying whichever amount is higher.¹ The WRS is one of the few fully funded state pension systems in the country, so the money promised to retirees is actually there.

Who Is Covered and When You Vest

Participation is mandatory. You don’t sign up; coverage begins on your first day as long as you meet the hours threshold. For teachers, that threshold is 440 hours with a single employer in one year.² Most educators fall into the “General/Teacher” benefit category.

Vesting is what gives you the right to the employer’s half of the money. If you first entered WRS-covered employment on or after July 1, 2011, you need five years of creditable service to vest. Anyone who was already a participant before that date was immediately vested under the old rules.³

If you leave teaching before vesting, you can only take a separation benefit: a refund of your own contributions plus accrued interest. The employer’s matching contributions stay in the system. Even a vested employee who withdraws funds before age 55 loses the employer match.³ Leaving the money in place until you reach retirement age is usually the better move if you have any thought of drawing it later.

What You and Your Employer Pay

For calendar year 2026, the employee required contribution for the General/Teacher category is 7.2% and the employer required contribution is 8.8%, for a combined 16.0% of salary.¹ The ETF Board resets these percentages each year. Your contribution is deducted pre-tax, which lowers your current taxable income.

Contributions flow into one of two investment funds:

The Core Fund is the default and holds a diversified mix of assets. Every contribution goes here unless you elect otherwise.
The Variable Fund is optional and invested entirely in stocks. If you elect in, 50% of future contributions go to the Variable Fund and 50% stay in the Core Fund. Higher growth potential comes with more volatility, including the possibility of negative adjustments to your annuity later.⁴

You can also make voluntary additional contributions on top of the required amount while you’re actively employed. The total of required plus additional contributions in any year cannot exceed the federal 415(c) limit, which is $72,000 for 2026.⁵ If you’re in the Variable Fund, half of your additional contributions go there too. Payments go directly to ETF by check or payroll deduction.⁶

How Your Benefit Is Calculated

ETF runs two separate calculations at retirement and pays you the larger result. This dual-calculation approach is one of the WRS’s genuinely generous features.

Formula Method

The formula method drives most teachers’ benefits. It multiplies three numbers:

Final Average Earnings × Years of Creditable Service × Formula Multiplier

Final Average Earnings are the average of your three highest annual earnings periods, which don’t have to be your last three years. Creditable service is the total of all years and partial years you worked under WRS coverage. The multiplier for General/Teacher employees is 1.6% for service earned after 1999. Service earned before 2000 uses a 1.765% multiplier, but only if you remained employed under the WRS after 1999.⁷

A teacher with $65,000 in Final Average Earnings and 30 years of post-1999 service would get: $65,000 × 30 × 0.016 = $31,200 per year, or $2,600 per month. The formula benefit is capped at 70% of Final Average Earnings for the General/Teacher category.

Money Purchase Method

The money purchase method treats your WRS account like a defined contribution balance. ETF takes the total accumulated value of your account (employee and employer contributions plus investment returns from the Core and Variable Funds) and multiplies it by an actuarial factor based on your age at retirement. The older you are when you start the annuity, the higher the factor.

This method tends to produce a higher benefit for people with fewer years of service but strong earnings, or those who made significant additional contributions. You don’t choose between the two methods; ETF automatically pays the larger amount.

When You Can Retire

The minimum age to begin drawing a WRS annuity in the General/Teacher category is 55. The normal retirement age for an unreduced benefit is 65.⁸ Retiring before 65 means your formula benefit is reduced actuarially, based on how many years early you start.

To receive any annuity, you must end all WRS-covered employment, be vested, and have reached at least age 55.⁸ If you leave before 55 or before vesting, your options narrow to a separation benefit or leaving the money in the system to accrue interest until you’re eligible. The trade-off between retiring at 55 with a smaller monthly check and waiting until 65 for a larger one is worth running the numbers on well before you make the call.

How Your Benefit Gets Paid

Annuity Options

You pick a payout structure when you apply, and the choice is permanent. It also directly affects any surviving spouse or beneficiary.

A Single Life Annuity pays the maximum monthly amount for your lifetime and stops when you die. No survivor receives anything.
A Joint Survivor Annuity pays a reduced amount while you’re alive, then continues a percentage of that payment to a named survivor after your death. You choose the survivor and the percentage in your original application, and changes afterward are restricted.²
A Temporary Annuity pays a larger amount before age 62 and reduces once you become eligible for Social Security. It’s designed to bridge income if you retire before 62.

Annual Adjustments

WRS annuities are not fixed. Every May, ETF adjusts your payment based on the actual investment performance of the fund backing your annuity. Adjustments can be positive or negative, and increases are not guaranteed. Core Fund annuities are reduced when the shortfall would require at least a −0.5% adjustment.⁹ Variable Fund adjustments swing more widely in both directions because of the all-stock portfolio. Electing the Variable Fund means accepting that some years your check will be noticeably smaller than the year before.

Buying Additional Service Credit

If your WRS history has gaps, you may be able to buy additional creditable service and raise your benefit. Eligible purchases include prior federal government employment, teaching service in another state, and qualifying military service.¹⁰

The cost is personalized. You request an estimate from ETF, which calculates what it would take to fund the added benefit. You’re limited to two purchases per calendar year under each service category, and you can’t buy credit that would push any single year past a full year of service. ETF expects full payment with the application, and if the actual cost comes in higher than the estimate, you have 30 days to pay the difference or withdraw the application.¹⁰ Allow at least four weeks for ETF to calculate the estimate, and longer if you’re close to retiring.

Social Security and Medicare Alongside the Pension

Unlike teachers in some other states, Wisconsin public school teachers are covered by Social Security through their WRS employment. State law requires teachers and state employees to participate in Social Security under a Section 218 Agreement, so Social Security taxes come out of your paycheck alongside your WRS contributions.¹¹ You receive both a WRS annuity and Social Security in retirement.

The federal Windfall Elimination Provision and Government Pension Offset historically reduced Social Security benefits for workers with pensions from non-covered employment. Because Wisconsin teachers pay into Social Security, those provisions generally did not apply to standard WRS teaching service. Both were repealed by the Social Security Fairness Act, signed into law on January 5, 2025, with the repeal applying to benefits payable from January 2024 forward.¹²

Medicare is a separate step. If you retire at or after age 65 and want to keep State Group Health Insurance coverage, you’re generally required to enroll in Medicare Parts A and B at retirement. Missing that enrollment window can create gaps in your health coverage, so coordinate with ETF and the Social Security Administration as your retirement date gets close.

Taxes on Your WRS Benefit

Your WRS annuity is subject to federal income tax, and Wisconsin state tax treatment generally follows the federal rules. Most retirees will owe state tax on their WRS benefits. A narrow exemption exists for members of certain pre-1964 retirement systems, but it applies only to individuals who were members of the Wisconsin State Teachers Retirement System as of December 31, 1963, with benefits paid from accounts established before 1964, so virtually no active teacher today qualifies.¹³

Social Security benefits are not taxable by Wisconsin. Your WRS annuity is taxed at both federal and state levels, but the Social Security portion of your retirement income is state-tax-free.¹³

Disability and Death Benefits

If you become disabled and can’t work until normal retirement age, the WRS Disability Retirement Program provides a lifetime annuity. The benefit is calculated using your actual creditable service plus assumed service through normal retirement age, which raises the payment well above what your actual years alone would produce.¹⁴ The separate Long-Term Disability Insurance program closed to new claims as of January 1, 2018, so teachers hired after that date rely on the Disability Retirement Program.

If a WRS member dies before retirement, the benefit to a beneficiary depends on the member’s age at death. For a death before age 55, beneficiaries receive the total account value: employee and employer contributions plus additional contributions and accumulated interest, or a partial payout limited to the employee’s own contributions and interest. For a death at 55 or older, the beneficiary receives the higher of the money purchase calculation or a special death benefit, mirroring the dual-calculation approach used for living retirees. Separate group life insurance and Wisconsin Deferred Compensation benefits may also apply if the member was enrolled.¹⁵

How to Apply

You can submit your retirement application to ETF as early as 90 days before your planned retirement date. Don’t wait too long on the back end either: if ETF receives your application more than 90 days after your retirement date, you may lose benefits. Start by requesting a Retirement Estimate and Application (Form ET-4301) from ETF, which gives you a personalized projection under both the formula and money purchase methods.¹⁶

Before filing, give written retirement notice to your supervisor and HR. If you or a dependent on your health insurance is 65 or older, start the Medicare Parts A and B enrollment process through the Social Security Administration at the same time. After you retire, your employer will send instructions for continuing any supplemental insurance you had while working.

Get your estimate well in advance. That extra time is what lets you compare annuity payout options, weigh whether purchasing additional service credit pays off, and coordinate your WRS start date with Social Security. Teachers who run the numbers early almost always make better payout-option decisions than those who rush the paperwork in their final weeks on the job.
