Tax Document Checklist for Seniors: What to Gather Before Filing

Walking into a free tax-prep site without the right documents wastes the volunteer's time and the taxpayer's appointment slot. Most sites will not start a return without proof of identity, a Social Security card or SSA letter, and last year's return. Seniors with a typical retirement profile carry a stack that almost always contains the same set of forms, and assembling the stack at the kitchen table the week before the appointment saves a return trip. The eight forms below cover roughly 95 percent of senior returns. The remaining 5 percent involve unusual items such as a Schedule C self-employment, a K-1 from a partnership, an inherited IRA in the first year, or a Roth conversion, and those documents should be added to the stack as they apply.

For identity, every taxpayer needs a photo ID, the Social Security card or a printed letter from the Social Security Administration showing the number, and last year's federal and state returns. For income, the SSA-1099 arrives in mid-January and shows Social Security benefits, Medicare premiums withheld, and federal tax withheld. The 1099-R, also January, shows pension, annuity, IRA, and 401(k) distributions plus federal tax withheld. The 1099-INT shows bank interest. The 1099-DIV shows brokerage dividends. The 1099-B shows brokerage stock sales with gain and loss summary. The 1099-NEC shows freelance or contract income. The W-2 shows wages from any part-time job. For deductions, the 1098 mortgage interest statement, the property tax bill, and a folder of medical receipts and prescription receipts matter only if the household itemizes, which a smaller share of seniors do under the current high standard deduction.

The single most common item missing on appointment day is the bank routing and account number for direct deposit. A senior without those numbers will receive a paper refund check by mail, which takes six to eight weeks. The numbers are printed on the bottom of a personal check, at the bottom of the bank's mobile app under direct deposit, or on a printed deposit slip. Bringing a voided check is the simplest path.
