Your Biggest Deductions

How Much a Deduction Actually Saves

A deduction lowers your net profit dollar for dollar, and that lowers two taxes at once: federal income tax and self-employment tax. Your savings are roughly the deduction times your federal bracket rate, plus about 14.1% for self-employment tax (15.3% of 92.35% of net profit, per the IRS). State tax savings are additional and vary by state.

Example: 15,000 business miles at the 2026 rates of $0.725/mile (Jan–Jun) and $0.76/mile (from July 1), split evenly (IRS Announcement 2026-11) is an $11,137.50 deduction (7,500 × $0.725 + 7,500 × $0.76). At a 12% federal bracket, that is about $1,337 in income tax plus about $1,574 in self-employment tax, or roughly $2,910. Your own bracket and income decide the real number.

Audit-Proof Your Deductions: The 4-Item Checklist

Schedule C filers have to be able to back up every deduction. Four practices keep your deductions defensible:

1. Contemporaneous mileage log. "Contemporaneous" means logged at the time of the drive, not reconstructed at year-end. IRS Publication 463 §5 requires this format: date, business purpose, starting odometer, ending odometer, miles driven. ShiftTracker captures this format natively at shift start/end.
2. Receipts for every non-mileage expense. Phone bills (with the business-use percentage noted), supply purchases, parking fees, toll receipts, tax prep invoices. Digital scans are accepted — IRS Pub 552 confirms electronic records satisfy the substantiation requirement.
3. Bank-deposit reconciliation. Match your 1099-NEC and 1099-K reported income against your bank deposits as soon as the forms arrive. Mismatches happen and require correction before filing.
4. 3-year record retention minimum. The IRS says to keep records for 3 years, or 6 years if you left out income that was more than 25% of the gross income on your return. Keep mileage logs, receipts, and 1099 forms in a labeled cloud folder organized by tax year.
