How the calculator works
The calculator multiplies the business miles you enter or allocate by each reviewed standard mileage rate effective in the selected filing year. It runs locally in your browser and does not verify whether individual trips qualify.

No saved numbers
The calculator does not send or save your miles or result. Website analytics does not receive those numbers.

Calculator FAQ
Answers before you use the estimate.
Understand the scope, privacy boundary, and limitations before relying on the result.
What does this calculator estimate?
It multiplies the business miles you enter or estimate by the configured standard mileage rate or rates for the selected filing year. The result is an estimated mileage deduction, not a refund or tax-savings amount.
Does the calculator decide which miles qualify?
No. You decide which business-mile assumptions to enter. Eligibility depends on the facts, applicable rules, and your records.
Is an estimated deduction the same as a refund?
No. A deduction may reduce income used in a tax calculation. It is not a dollar-for-dollar refund, and the effect on taxes depends on your complete situation.
Are my miles or result saved?
No. Phase 1 calculates the estimate in your browser and does not send or save the mileage inputs or result. Website analytics and Apple’s App Store systems are separate and do not receive these calculation values.
Why do I have to choose a filing year?
Standard mileage rates can change by year or within a year. The calculator uses reviewed, effective-dated rates and rejects unsupported years instead of substituting a different rate.
How can GigClaim help after this estimate?
GigClaim helps you track work sessions, review missed or uncertain trips, and export records when you choose. It provides recordkeeping and planning tools, not tax advice or filing.
How does the calculator handle the 2026 rate change?
It applies 72.5 cents per mile to business miles from January 1 through June 30 and 76 cents per mile to business miles from July 1 through December 31. You allocate miles or active weeks between the periods; the calculator never uses a silent annual average.
