Please take note of the following annual events that affect you as a retired TRS member:
Federal income tax withholding (W-4P) form
TRS cannot give tax advice. You may wish to contact a qualified tax advisor or the Internal Revenue Service at (800) 829-1040 to ensure that you have adequate federal withholding for the 2026 tax year. If you are underwithholding, there could be a negative consequence at tax time.
If you would like to change your withholding election, you must complete a new Form W-4P. You can call your local Internal Revenue Service office for a blank form or download the blank W-4P Withholding Certificate for Pension or Annuity Payments form from the IRS website: http://www.irs.gov/pub/irs-pdf/fw4p.pdf. A new Form W-4P replaces any former withholding on file with TRS.
You may return the form by:
- Uploading it in MyTRSIL, https://www.trsil.org/myTRSIL:
- From your member account page, locate Member Services on the left navigation bar.
- Under Member Services, select Document Upload.
-
Mailing it to:
Teachers’ Retirement System
PO Box 19253
Springfield, IL 62794-9253 - Fax it to: (217) 753-0964
1099-R Form
If you received a TRS benefit in 2025, the Office of the Comptroller will mail an IRS Form 1099-R to you by Jan. 31, 2026. This form will report your income received from TRS during 2025.
The amount shown in Box 5 on the 1099-R form represents the non-taxable portion of TRS retirement benefits paid to you for the year (see graphic below) and is the difference between Boxes 1 and 2a. Box 5 does not represent the amount of your TRIP premiums for 2025. Box 9B will only have a value if 2025 was the first year that you received a benefit from TRS.
If you do not receive a 1099-R form by Feb. 16, 2026 or you need a duplicate copy sent to you, please log in to your MyTRSIL member account. Annually after Feb. 16, you may request a duplicate 1099-R online for a prior year. After accessing your MyTRS member account, select the Forms & Reports from the navigation bar. When the options are shown, select the 1099-R duplicate request.
If you have not yet set up your online MyTRSIL member account, please watch this video to learn how: https://www.trsil.org/video/Accessing_MyTRSIL. Your Member ID is required to set up an account.
Members may also request a duplicate 1099-R by calling TRS at (877) 927-5877. It may take up to 10 business days to receive your duplicate copy in the mail.
