About the Mileage Deduction Calculator
The mileage deduction is the biggest routinely-underclaimed line on Schedule C — and 2026 is the year to get it precisely right, because the IRS did something rare: it raised the rate mid-year. 72.5¢ per business mile through June 30; 76¢ from July 1 (both verified at irs.gov). Every tool that applies one rate to the whole year is now quietly wrong in one direction or the other.
This one computes the split correctly, compares the actual-expense method honestly (it wins more often than freelancers assume), and prices your miles in real tax saved — SE tax plus income tax at your marginal rate, using the same Node-validated engine as the S-Corp and paycheck calculators.
Publication 463’s fields: date, destination, business purpose, miles — plus the January-1 and December-31 odometer lines that establish your total. Download the template, keep it in the car or the cloud, record trips when they happen.
How to Use the Mileage Deduction Calculator
Enter your business miles for each half of 2026 — or one annual figure, split evenly with the assumption stated — plus your profit and filing status. The deduction comes back computed with the actual two-rate year, and the tax panel translates it into real dollars: what those miles remove from your self-employment tax and income tax combined.
Why 2026 Is Different
Mid-year rate changes are rare — the IRS has done it only a handful of times, most recently in 2022’s fuel spike. For 2026 the business rate opened at 72.5 cents and rose to 76 cents on July 1. The practical consequence: your log needs to separate first-half from second-half miles, and any calculator, spreadsheet or app that multiplies one rate by annual miles is off by up to 3.5 cents a mile on half your driving. This page leads with the split because that is the year’s actual shape.
The Commuting Line Nobody Likes
Home to your regular workplace is commuting, and commuting is never deductible — no matter what is in the trunk. The exception that swallows the rule for many freelancers: if your home office qualifies as your principal place of business, driving from home to any client or job site is business mileage. That single qualification often doubles a legitimate deduction, which is why it is worth getting right (and documented) rather than guessed.

Educational estimates, not tax advice. 2026 rates verified at irs.gov (72.5¢ Jan–Jun, 76¢ Jul–Dec business; 26¢ medical/moving-qualified; 14¢ charitable, statutory). The tax-saved figure uses the standard deduction and assumes the mileage deduction doesn’t change your bracket mid-dollar; depreciation interactions (Section 179, bonus, standard-rate lockout) belong with a professional.
Frequently Asked Questions
What is the IRS mileage rate for 2026?
Two rates, unusually: 72.5 cents per business mile from January 1 through June 30, then 76 cents from July 1 through December 31 — the IRS raised it mid-year citing fuel and operating costs, something it has done only a handful of times in history. Both figures were verified at irs.gov. Most calculators (and plenty of accountants' spreadsheets) will quietly apply one rate to the whole year; on 20,000 business miles the difference is $350 of deduction.
Standard mileage or actual expenses — which is better?
The standard rate bundles fuel, maintenance, insurance and depreciation into one per-mile figure and needs only a mileage log. The actual method deducts your real costs times the business-use percentage — more paperwork, but it wins for expensive, thirsty or heavily-depreciating vehicles driven mostly for business. Rough break-even: if your true all-in cost per mile beats the standard rate, actual wins. One trap: choosing actual with depreciation in a car's first year generally locks you out of the standard rate for that car later.
What actually counts as business miles?
Driving between work sites, to clients, to the bank or supply store for the business, and from a home office that qualifies as your principal place of business to any work location. What never counts: ordinary commuting between home and a regular workplace — the largest category of miles people wrongly claim. Medical (26¢/mile in 2026) and charitable (14¢, set by statute) miles are separate deductions with their own rules.
What records do I need if audited?
A contemporaneous log: date, destination, business purpose, and miles for each trip, plus the odometer at the start and end of the year to establish total miles. "Contemporaneous" means recorded at or near the time — a log reconstructed in April reads exactly like a log reconstructed in April. The template here has precisely those fields, and the year-end odometer lines, because they are what Publication 463 describes.
How much tax does a mile actually save me?
For the self-employed, more than people think: the deduction reduces income subject to BOTH self-employment tax (15.3% up to the wage base) and income tax at your marginal rate. At a 22% bracket, a second-half-2026 mile is worth roughly 76¢ × (15.3% × 0.9235 + 22%) ≈ 27¢ of real tax. The panel computes your figure from your actual profit level using the same validated engine as our S-Corp and paycheck calculators.
