Mileage Reimbursement Calculator
Calculate your mileage reimbursement or deduction using current IRS standard mileage rates. Covers business (67 cents/mile), medical (21 cents/mile), and charity (14 cents/mile) rates for 2024. See monthly and annual totals.
The IRS standard mileage rate is the simplified per-mile rate businesses and individuals can use to calculate vehicle-related tax deductions or reimbursements. For 2024, the rates are: 67¢/mile for business use (the most common), 21¢/mile for medical or moving (very limited eligibility), and 14¢/mile for charitable purposes. These rates are adjusted annually by the IRS based on fuel prices, vehicle costs, insurance, and other factors. The business rate covers gas, oil, repairs, insurance, registration, and depreciation — all rolled into a single per-mile number.
For self-employed individuals and business owners, mileage deduction is one of the most commonly claimed (and frequently overlooked) tax benefits. Driving 15,000 business miles annually at 67¢/mile generates $10,050 in deductions. At a 30% combined tax bracket, that's $3,015 in tax savings annually. For employees, federal tax law (post-2017 TCJA) no longer allows unreimbursed employee business expense deductions, so accurate employer reimbursement at IRS rates is the only path to capturing this value. Many employers reimburse below the IRS rate (e.g., 50¢/mile), which means employees should track mileage and negotiate appropriately.
This calculator computes mileage reimbursement/deduction using the current IRS standard rates. Use it for: tracking annual deductible miles, monthly expense reporting, evaluating employer reimbursement adequacy, estimating tax impact of mileage deductions, and planning for upcoming tax filings. Important context: you cannot mix methods — choose between standard mileage rate OR actual expenses (gas, repairs, depreciation, insurance, etc.) for the year. Standard mileage simpler; actual expenses sometimes higher for vehicles with high operating costs (luxury, high-maintenance, low MPG). Accurate mileage logs are required either way — IRS requires contemporaneous record (date, miles, business purpose, beginning/ending odometer). Apps like MileIQ, QuickBooks Self-Employed, and Stride automate this.

Formula
How to use this calculator
- Enter miles driven (for the period — single trip, week, month, or year).
- Select mileage type — business is most common; medical and charitable have limited applicability.
- Select frequency — calculates one-time amount, weekly accumulation, monthly, or annual totals.
- Review reimbursement or deduction amount.
- For self-employed: this is your deduction on Schedule C (Form 1040). Reduces both income tax and self-employment tax.
- For employees: this is the reimbursement amount your employer should pay (or close to). Federal tax law no longer allows unreimbursed employee business expense deductions.
- For tracking: use a mileage app (MileIQ, QuickBooks Self-Employed, Stride) for IRS-compliant contemporaneous records. After-the-fact logs aren't accepted in audits.
- For annual planning: estimate your annual business miles, multiply by IRS rate, calculate tax savings at your bracket. Often $2,000-$5,000+ in tax savings annually.
- For comparison to actual expense method: track both for one year — see which method produces higher deduction for your specific vehicle. Switch if applicable (first year choice).
- Keep records 3 years past tax filing (IRS audit window).
Worked examples
Self-employed consultant
Consultant drives 18,000 business miles/year visiting clients. Annual deduction: 18,000 × 67¢ = $12,060 Tax savings: 22% federal bracket: $2,653 22% federal + 5% state: $3,256 Plus self-employment tax savings: $12,060 × 14.13% effective SE = $1,704 Total annual tax savings: ~$4,960 Significant deduction. Most self-employed individuals underclaim mileage due to poor tracking. Using mileage app catches all business miles automatically — captures $1,000-$2,000+ in additional deductions vs. self-reported tracking. Plus deductible: tolls and parking ($200-$500 typical), separately from mileage rate.
Real estate agent — high mileage
Real estate agent drives 30,000 business miles/year (showing properties, client meetings, area tours). Annual deduction: 30,000 × 67¢ = $20,100 Tax savings: 24% federal bracket: $4,824 24% federal + 7% state: $6,231 Plus SE tax: $20,100 × 14.13% = $2,840 Total: ~$9,070 annual tax savings For high-mileage professionals (real estate agents, sales reps, contractors), mileage deduction is among the largest single deductions on tax return. Worth ~$10K/year for 30K-mile drivers. Compare to actual expense method for older or high-maintenance vehicles. If actual gas + maintenance + insurance + depreciation > $20K for 30K business miles, actual method better.
Employee reimbursement at company rate
Sales rep drives 12,000 business miles/year. Employer reimburses at 50¢/mile (below IRS 67¢ rate). Employer reimbursement: 12,000 × 50¢ = $6,000 IRS rate equivalent: 12,000 × 67¢ = $8,040 Underpayment: $2,040/year ($170/month) Pre-TCJA (before 2018), the $2,040 gap was deductible as unreimbursed employee business expense. Post-TCJA, this deduction was eliminated for W-2 employees. Options for sales rep: 1. Negotiate higher reimbursement rate (cite IRS standard 67¢) 2. Track total business miles carefully — employer may reimburse for additional miles missed 3. Discuss accountable plan with employer (separate $X/month auto allowance — taxable to employee but doesn't require itemization) 4. Discuss vehicle benefits (company car, fuel cards) For 1099 contractors at same situation: the $8,040 is fully deductible on Schedule C regardless of what client pays. Big advantage of contractor status for high-mileage workers.
When to use this calculator
Use this calculator for tracking deductible business mileage, calculating tax deductions for self-employed individuals, estimating employer reimbursement adequacy, planning annual mileage-based tax savings, or comparing to actual expense method.
Pair with self-employment-tax (overall self-employment tax planning), fuel-cost (per-trip cost analysis), and tax calculators for broader planning.
Important mileage deduction considerations:
1. **Contemporaneous records required.** IRS requires real-time mileage logs (date, miles, business purpose, odometer readings). After-the-fact reconstruction usually denied in audits. Use mileage apps for compliance.
2. **Standard vs. actual expense method choice locked in early.** First year of business use chosen method. Standard mileage can switch to actual later; actual cannot switch to standard. Choose carefully.
3. **Commuting NOT deductible.** Trips between home and primary office are personal commute, never deductible. Exception: home office qualifying as principal place of business — trips from home office to clients/sites then deductible.
4. **TCJA eliminated employee business expense deduction.** W-2 employees can no longer deduct unreimbursed mileage on personal returns (post-2017). Only self-employed and accountable plan reimbursement provide tax benefit.
5. **High-mileage drivers often prefer actual expense.** Luxury vehicles, high-maintenance vehicles, low MPG vehicles may have higher actual costs than standard mileage rate captures. Track both methods first year to compare.
6. **Rate covers ALL vehicle costs except parking and tolls.** Don't double-dip — can't deduct insurance, repairs separately when using standard mileage. Those costs are included in the rate.
7. **Self-employment tax savings amplify mileage benefit.** Mileage deduction reduces net SE income, reducing both income tax AND 15.3% SE tax. Effective tax savings rate often 35-45% of mileage amount.
8. **Apps automate compliance.** MileIQ, QuickBooks Self-Employed, Stride, Hurdlr automatically track drives via GPS and let you classify as business/personal. Captures 20-50% more deductible mileage than self-reported tracking.
9. **Rate changes annually.** IRS announces new rates each November/December for following year. Check current rate before filing.
10. **Mid-year rate changes possible.** IRS has occasionally adjusted business mileage rate mid-year for fuel price spikes (last in 2022). Track miles separately for each rate period.
11. **State rates may differ.** Some states have separate state-level mileage rates for state income tax. Check your state.
12. **Vehicle ownership requirement.** Standard mileage requires you own or lease the vehicle. Cannot use for vehicle owned by employer or for occasional rental.
Common mistakes to avoid
- Not tracking mileage contemporaneously. After-the-fact reconstructed logs typically denied in IRS audits.
- Deducting commuting mileage. Trips between home and primary office are personal, never deductible.
- Mixing standard and actual expense methods. Must use one or the other for the entire year for a vehicle.
- Self-reporting estimates without records. Mileage apps capture 20-50% more legitimate business mileage than self-reported estimates.
- Underclaiming as employee post-TCJA. Federal employee business expense deduction eliminated; negotiate employer reimbursement at IRS rate instead.
- Forgetting parking and tolls. These are separately deductible beyond standard mileage rate.
