How to Know Which Receipts to Save for Taxes

The hardest part of saving receipts is not the saving. It is knowing which ones matter. If you save every piece of paper that comes through the door, the pile becomes useless. If you toss too much, you may miss real deductions or have nothing to show the IRS if questions come up later. The good news for most seniors is that the list of receipts that actually matter for federal taxes is shorter than people think. The standard deduction in 2026 is high enough that many retirees do not itemize at all, which means most everyday receipts can go straight in the recycling. But there are still six categories that almost always matter, and those are the ones to track.

The first category is medical expenses. This includes prescriptions, doctor co-pays, dental visits, eyeglasses, hearing aids, Medicare premiums, supplemental insurance premiums, long-term care insurance premiums, and miles driven to medical appointments. Medical expenses only count above 7.5 percent of your income, but seniors often hit that number, especially in years with surgery or new hearing aids. The second category is property taxes and mortgage interest, both of which arrive on official forms in January. The third is charitable donations, both cash and goods donated to thrift stores like Goodwill and Salvation Army.

The fourth category is state and local taxes paid, including state income tax and vehicle registration fees in some states. The fifth is investment-related paperwork: 1099-DIV forms for dividends, 1099-INT for interest, and 1099-B for stock sales, plus records of what you originally paid for any stocks you sold during the year. The sixth is anything related to a home sale, a rental property, or a small business, which gets complicated and is worth talking to a tax preparer about.

What can you toss? Grocery receipts, gas receipts unless you drive for medical appointments or charity, restaurant bills, clothing receipts unless donated, utility bills unless you have a home office, and most regular household purchases. Bank statements are nice to keep for one year for your own records. But they are not tax documents. Credit card statements are the same. The IRS will ask for the underlying receipts, not the statements. When in doubt, drop the receipt in the "Questions" pocket of your folder and let your tax preparer sort it out at the end of the year. That is what they are paid for.
