IRS Tax Tip 2025-10 names the year-end documents most taxpayers should receive: Forms W-2, 1099-MISC, 1099-INT, 1099-NEC, 1099-G and 1095-A. Add brokerage forms and K-1s from last year’s return.
Form 1099-K now goes out only when a seller’s gross payments exceed $20,000 and transactions exceed 200, per IR-2025-107. Clients below that may get no form but still have income to report, so ask for platform statements.
From 2025, qualifying clients can deduct qualified tips, the overtime premium, car loan interest on a qualifying new vehicle, and an extra amount for seniors. Each has its own records. Add the relevant checklist only for clients who might qualify.
For a client with a side business kept in HelloBooks, Schedule C income and expenses come from the ledger. The checklist then only needs the third-party forms and personal deduction records.
