Taxation of Pension Benefits

Taxation of Pension Benefits

Your Massachusetts public retirement allowance is taxed under both federal and state law — but the rules differ in important ways.

The Eldridge Bay Retirement System cannot give individual tax advice. This page is general information. For tax planning specific to your situation, consult a CPA or enrolled agent familiar with public-pension taxation.

Federal income tax

Most of your retirement allowance is federally taxable as ordinary income.

The exception: any portion of your benefit that comes from post-tax member contributions is recovered tax-free over your expected remaining life expectancy under the IRS "Simplified Method" or the "General Rule" depending on your annuity start date. The result is an "exclusion ratio": a small percentage of each monthly check is tax-free; the rest is taxable. The board reports the taxable amount on your annual 1099-R.

The vast majority of your benefit will be taxable, because most of the value of the pension comes from the employer's contributions, the investment returns on the fund, and any pre-tax member contributions.

Federal withholding

You may elect federal income tax to be withheld from your retirement check by filing IRS Form W-4P with the board's office. You can adjust the withholding at any time. If you don't withhold, you may owe quarterly estimated tax payments to the IRS.

1099-R

Each January, the board issues a Form 1099-R for the prior tax year. It shows:

  • Gross distribution (Box 1)
  • Taxable amount (Box 2a)
  • Federal tax withheld (Box 4)
  • Distribution code (Box 7) — typically "7" for normal retirement, "3" for disability, "4" for survivor benefits

The 1099-R is also available in the Member Portal. If you don't receive it by mid-February, contact the board.

Massachusetts state income tax

Massachusetts does not tax the portion of your retirement benefit that comes from the Massachusetts public retirement system. Specifically:

  • Your monthly retirement allowance from the Eldridge Bay Retirement System, MTRS, MSRB, or any other MA public retirement system is not subject to Massachusetts income tax.
  • A refund of your member contributions is partially taxable on the state side — the interest portion is taxable; the contribution portion (if made post-tax) is generally not.

This is a real cash advantage for Massachusetts residents over public retirees in many other states. Some states (e.g., New York, New Jersey) tax their public-pension retirees in full.

State withholding

You may also elect Massachusetts state income tax withholding by filing Form M-4P with the board's office. Since the allowance itself isn't MA-taxable, this only matters if you have MA tax owing for other income (Social Security, investment income, part-time work, etc.) and you want it withheld through this paycheck.

Moving out of state

If you move out of Massachusetts in retirement, your benefit becomes subject to your new state's tax law, not Massachusetts's. Some states tax public pensions; some don't. New Hampshire and Florida have no state income tax at all. Ask your tax professional about the tax consequences of any planned move.

The board honors a change of state residence — including for tax-withholding purposes — once you notify us. Use the form in the Member Portal or contact the office.

Disability retirement tax treatment

For tax purposes, accidental disability retirement benefits paid under MGL Chapter 32 § 7 are partially excluded from federal income tax under IRC § 104(a)(1) — they're treated as workers'-compensation-like payments. The exclusion is recorded on your 1099-R via the distribution code.

Ordinary disability retirement benefits (§ 6) are generally fully taxable like superannuation benefits.

This is a complex area. Consult a tax professional.

Survivor benefits

A spouse or beneficiary receiving an Option C survivor allowance, an Option B refund, or a § 100 line-of-duty death benefit receives a 1099-R and is taxed on the same federal/state framework that applied to the retiree.
