Mileage Deduction Calculator (2026)

Miles add up to deductions—if you qualify

Taxpayers who drive for business, medical appointments, qualified moving, or charitable work may deduct vehicle costs via standard mileage rate per mile or actual expense allocation. Commuting to the office generally does not count. Gig workers and Schedule C filers often live in mileage logs; W-2 employees face tighter rules after TCJA suspended miscellaneous itemized employee business expenses for most workers.

This calculator multiplies miles by the rate you enter for each category and shows approximate deduction dollars. Verify current IRS rates on the newsroom each January—2026 rates publish with inflation and fuel adjustments.

Self-employed business miles tie to the self-employment tax calculator; medical miles interact with the medical expense deduction calculator 7.5% AGI floor.

Categories of driving

• Business (Schedule C): Client visits, supply runs, between job sites—not home to first site
• Medical (Schedule A): Doctor, pharmacy, hospital—subject to 7.5% AGI floor with other medical
• Charitable (Schedule A): Lower statutory rate; driving for qualified nonprofit
• Moving (Schedule A): Armed forces move under orders; civilians largely repealed

Standard rate vs actual method

Standard mileage bundles depreciation implicitly—simple: miles × rate. Actual method tracks gas, oil, repairs, insurance, registration, lease payments, depreciation scaled by business use percentage. Luxury cars and high repair years may favor actual; low-mileage efficient cars may favor standard.

Switching methods after first year has restrictions—plan before first business return.

How to use the calculator

Step 1 — Log miles by category

Separate business from personal rigorously—commuting stays out.

Step 2 — Enter IRS rate for each category

Business rate exceeds charitable rate historically.

Step 3 — Read deduction estimate

Medical miles only count after 7.5% AGI floor on total medical—enter AGI in medical tool.

Worked example (Schedule C consultant, 2026)

8,000 business miles × illustrative 67¢/mile ≈ $5,360 deduction reducing net profit on Schedule C. That lowers income tax and self-employment tax base. 500 medical miles × lower medical rate adds to Schedule A medical pool before AGI floor—not automatic full deduction.

EV and hybrid notes

Standard mileage rate applies to electric vehicles same as gas—the rate is not fuel-type specific. Actual method might include home charging allocation with documentation.

Parking and tolls

Often deductible in addition to standard mileage for business—enter separately in actual expense workflows; check IRS pub for current year treatment with standard rate.

Common mistakes

• Deducting commute because “thinking about work”
• Using business rate for charity miles
• No written log until audit letter arrives
• W-2 employee assuming home office miles without qualifying reason
• Ignoring AGI floor on medical mileage

Additional planning notes for 2026

Tax software and professional preparers reconcile annual Form 1040 liability against W-2 withholding—not any single calculator snapshot. Use the interactive form above as a transparent starting point, then validate filing status, dependents, and pre-tax elections before you treat output as a filing estimate. Where this page references 2026 figures, they follow IRS Rev. Proc. 2025-32 and SSA wage base announcements unless noted otherwise.

Federal ordinary rates remain 10%, 12%, 22%, 24%, 32%, 35%, and 37%. Employee FICA is 6.2% on wages up to $184,500 plus 1.45% Medicare on all covered wages. Additional Medicare Tax at 0.9% applies above $200,000 single / $250,000 joint / $125,000 MFS. Standard deduction amounts are $16,100 single and married filing separately, $24,150 head of household, and $32,200 married filing jointly.

State residency, local income taxes, and voluntary payroll deductions can move cash results without changing the federal concepts modeled here. When a scenario spans multiple jobs, side income, or mid-year life changes, pair this page with the federal income tax calculator, paycheck calculator, and tax refund estimator so withholding, liability, and refund expectations stay aligned.

Documentation matters at filing time: retain 1098 and 1098-E forms, charitable acknowledgments, medical receipts, mileage logs, and employer plan confirmations that support positions you claim. Rounding in browser tools may differ slightly from payroll systems that round per pay period.

Recordkeeping and next steps

Keep source documents that support inputs you enter—pay stubs, Form W-2, 1098 series forms, receipts, and employer benefit summaries. Calculators on this site show math in the open for learning; they do not e-file returns or transmit data to the IRS. When results look close to decision thresholds (itemizing vs standard deduction, credit phaseouts, or installment affordability), rerun the scenario with conservative and aggressive assumptions to see sensitivity.

Use this page alongside the state and federal tools that match your filing status. Related calculators on this site keep year-scoped datasets separate so a 2025 habit does not silently reuse a 2026 constant.

Verification checklist before filing

Before you rely on any estimate for a financial decision, reconcile these inputs against source documents: filing status on the return you will actually file, total wages from all W-2 box 1 amounts, pre-tax deferrals that reduce taxable wages, and any credits or deductions you qualify for beyond the simplified fields on this page. A single missing 1099 or an outdated W-4 at a second job can shift liability by more than rounding error in browser math.

If you itemize, confirm Schedule A components together—SALT capped at $10,000, mortgage interest limited on acquisition debt over $750,000 for post-2017 loans, medical expenses only above 7.5% of AGI, and charitable gifts within AGI-based caps. Standard deduction filers should still model above-the-line adjustments such as student loan interest up to $2,500 and HSA contributions where applicable.
