Montana Public Employee Retirement Administration
MPERA will mail all 1099-R tax forms by January 31, 2025. All Change of Benefit notices will also be sent by the end of January. These documents should arrive by the first week of February.

 

Income Taxes

Your monthly benefit is reported to the IRS as income, and you are responsible for paying any taxes. You will receive a Form 1099-R annually for tax reporting purposes. If you made contributions to your retirement account after-tax, such as with a service purchase, the non-taxable portion of your retirement paid throughout the year will be reported on your 1099-R form in Box 5. You will complete a Tax Withholding form when you apply for retirement to indicate how much federal and state income tax you want withheld.

 

IRS Form 1099-R

MPERA mails the 1099-R forms before the end of January of each year. Retirees who haven’t received their 1099-R form by the middle of February should call MPERA to request a duplicate. If you've changed your address recently, update your address with MPERA before the end of December to receive your 1099-R form by mail. You can change your address by completing a change of address form (PDF) for retirees.

Many members receive only one 1099-R, but there are instances where multiple forms are generated:

  • If you took an early retirement and reached normal retirement age during the year. For example: as a PERS member, if you retired early then turned 59½ during the past year. The pre-59½ payments are coded “2” (early distribution) and the post-59½ payments are coded “7” (regular distribution).
  • Receiving two benefits from a plan, perhaps as both a survivor beneficiary and as a retiree.
  • Receiving distributions from two different plans (i.e. MPORS member and PERS member, retired from both plans).
  • Multiple refunds with different tax consequences (portion rolled over to a qualified plan like a 401 or 457, part taken directly).
  • You may also receive a separate 1099-R associated with any 457 Plan distributions you may have taken. 

When filing your taxes, you'll need to add the appropriate figures from separate 1099-R forms together.
