8 Documents Your Accountant Wishes You Kept All Year Every accountant has the same story about April. A client shows up with a shoebox, a few guessed-at numbers, and a plea to make it work. The return gets filed, but deductions get missed, fees run higher, and the whole thing takes longer than it should. The fix is boring and it works: keep the right documents all year, not the week before filing. Here are the eight your accountant wishes you had. Keep these current and your tax season goes from a scramble to a handoff. 1. A Contemporaneous Mileage Log If you deduct vehicle expenses, the IRS expects a record kept at the time of the trip, not reconstructed from memory in April. Date, destination, business purpose, and miles. A phone app that logs automatically is fine, and often better than a notebook you forget to fill in. A clean log protects a legitimate deduction. The limitation is that a vague or backfilled log is exactly what gets disallowed in an audit, so consistency matters more than perfection. 2. Receipts for Anything You Cannot Prove With a Statement A bank or card statement shows that you spent money, not what you bought or why it was for business. For larger or unusual expenses especially, keep the itemized receipt. Snap a photo and file it digitally so a faded thermal receipt does not cost you the deduction. Good receipts turn a questionable line item into a defensible one. They will not make a personal expense deductible, so the habit is to capture the business ones, not to stretch the definition. 3. Reconciled Bank and Credit Card Statements Your accountant builds your return on your books, and your books are only as good as the reconciliations behind them. Keep every business bank and credit card statement, and reconcile monthly so the year-end numbers are not a surprise. Reconciled statements mean fewer questions and a faster, cheaper return. The catch is that reconciliation only works if business and personal spending are separated, which is a strong argument for dedicated business accounts. 4. Every 1099 and Income Record Track the income documents that flow to you across the year: 1099-NEC, 1099-K, 1099-INT, and the rest, plus your own record of what you actually earned. The forms you receive are also reported to the IRS, so mismatches invite notices. Complete income records let your accountant reconcile forms to reality. Remember that a 1099 is not the same as your taxable income, so your own books remain the source of truth. 5. Asset Purchase Invoices for Depreciation When you buy equipment, vehicles, or other long-lived assets,...
