2020 1099-R Forms Have Been Mailed

Jan 26, 2021, 13:20 PM

You will need this important form to file your taxes. See our Understanding Your 1099-R Form flyer to learn more. We have sent it to you if, in 2020, you were a:

  • Member who received retirement benefits
  • Survivor or beneficiary who received monthly benefit payments
  • Survivor or beneficiary who received a final benefit payment
  • Ex-spouse who received a monthly benefit
  • Former state employee who elected a refund of your employee contributions to MOSERS

Please note:

MOSERS does NOT send W-2 Forms to active state employees - those come from your employer.

MOSERS is a public pension for tax reporting purposes.


For immediate access to your 1099-R or if you find you need a replacement copy of it, log in to myMOSERS. You will find your 1099-R under Personal Information and available for you to print or save.


If you are a Missouri resident, you may qualify for the Public Pension Exemption. Visit the Missouri Department of Revenue's Public Pension Exemption page or read our Missouri Public Pension Exemption flyer for more information.

In order to be eligible for the full deduction, your Missouri adjusted gross income must fall within certain income limitations. If your income exceeds the limitation, you may qualify for a partial exemption.

Contact the Missouri Department of Revenue to see if you qualify or ask a tax professional.


Your MOSERS retirement benefits are subject to federal income tax, and Missouri state income tax, if you reside in Missouri. If you wish to adjust your withholdings for future payments but need more information, we have some helpful calculators on the  Taxes page on our website:

If you do not choose a federal tax withholding option on the Substitute W-4P form, we are required to withhold federal taxes as if you elected “married with three allowances”.

You may change your withholding election at any time during the year by submitting a Substitute W-4P form to MOSERS. You can fill out a PDF of the Substitute W4-P form online, print it, and mail it to MOSERS, or you can log in to myMOSERS and submit it electronically. Once you are on your homepage, click on Forms (in the top menu) then on Tax Withholding, and follow the prompts. The amount of withholdings you elect does not change your tax liability.

Please keep in mind that while MOSERS benefit counselors are happy to answer any questions you may have about your retirement, life insurance, or long-term disability benefits, they are not tax experts and cannot advise you on matters related to state or federal taxes. If you have questions regarding this information, we suggest you contact a tax advisor.
