Question 1

How do I calculate my mileage tax deduction for 2026?

Accepted Answer

Multiply your total business miles for the year by the 2026 IRS standard mileage rate of $0.725 per mile. For example, 15,000 business miles × $0.725 = $10,875 in deduction. That deduction reduces your Schedule C net profit, which lowers both your federal income tax and your self-employment tax. A driver in the 22% federal bracket saves roughly $2,393 in federal tax on a $10,875 deduction, plus an additional ~$1,500 in self-employment tax savings.

Question 2

What is the 2026 IRS mileage rate?

Accepted Answer

The 2026 IRS standard mileage rate for business use is $0.725 per mile (72.5 cents). This rate covers gas, oil, tires, depreciation, insurance, and routine maintenance. It applies to all business miles driven by 1099 gig workers — DoorDash, Uber, Lyft, Instacart, Walmart Spark, Amazon Flex, Grubhub, and any other 1099 self-employed driving.

Question 3

Do I need to track every single mile for the IRS?

Accepted Answer

Yes — IRS Publication 463 requires a contemporaneous log showing date, business purpose, starting and ending odometer readings, and miles driven for each business trip. Estimating or reconstructing miles after the fact is risky if audited. Odometer-based logging at shift start and shift end is the format the IRS specifically asks for and the most audit-defensible.

Question 4

Can I claim the mileage deduction AND actual vehicle expenses?

Accepted Answer

No — you must pick one method for the entire year per vehicle. The standard mileage method ($0.725/mile in 2026) is simpler and usually larger for high-mileage gig drivers. The actual expense method (gas + maintenance + depreciation + insurance + registration) sometimes wins for luxury vehicles or low-mileage drivers. Once you choose the actual expense method on a vehicle, you generally can't switch back to standard mileage.

Question 5

How does the mileage deduction affect my self-employment tax?

Accepted Answer

The mileage deduction reduces your Schedule C net profit, which reduces both federal income tax AND the 15.3% self-employment tax on net SE earnings. A $10,875 mileage deduction at a 22% income tax bracket plus 15.3% SE tax saves approximately $4,000 in combined federal taxes — more if you're in a higher bracket.
