What each log is for
Mileage: the date of each trip matters in 2026
If you take the standard mileage deduction, you need a record of each business trip: Publication 463 (chapter 5) names the date, your business destination, the business purpose, and the miles. A log kept weekly counts as made at or near the time. In 2026 the IRS business rate is 72.5 cents a mile through June 30 and 76 cents a mile from July 1 (IR-2025-128, IR-2026-29), so the date column also decides which rate applies. The mileage deduction calculator adds up both periods and estimates the tax it saves.
Tips: report by the 10th, and keep the record
Publication 531 says tipped employees must keep a daily record of the tips they receive and pay out, and report tips of $20 or more in a month (per job) to their employer by the 10th of the next month. Reported tips end up on your W-2, and that matters more now: for 2025 through 2028, you may be able to deduct up to $25,000 of qualified tips on Schedule 1-A, which starts from the tips shown on a W-2, 1099, or Form 4137.
Income and expenses: books that match Schedule C
Publication 583 says your books must show your gross income and your deductions, backed by receipts, invoices, deposit slips, and statements. Coding each row with its Schedule C line means the year-end job is adding up each code. The same totals drive your quarterly estimated tax; the quarterly estimated tax calculator shows what to pay by each due date, and the self-employment tax calculator shows the Social Security and Medicare part.
Rather keep it in a spreadsheet?
The Freelancer Tax Tracker for Excel does the income and expense log, Schedule C totals, and quarterly estimated tax in one workbook.
