The Mileage tab: each trip's miles, with the IRS rate for its date (72.5 cents before July, 76 cents after) and the deduction. — Mileage: the IRS rate is filled in by date.

Questions

Why are the payment periods uneven?

The IRS sets them that way: January to March, April and May, June to August, and September to December. Each payment covers the income of its period.

Why does it ask about June miles?

The IRS mileage rate for 2026 changed on July 1, and the June to August period straddles that date, so June miles count at the lower rate.

Is the amount it shows my tax?

No. It is your chosen percentage of the profit you enter, as a savings target. What you actually owe depends on your whole year; ask a tax professional.

Do you keep what I type?

No. The calculator runs only in your browser and sends nothing anywhere.

Where the numbers come from

IRS business standard mileage rate for 2026: 72.5 cents a mile from January 1 to June 30, and 76 cents a mile from July 1 to December 31 (IRS IR-2025-128 and IR-2026-29). Estimated tax due dates: April 15, June 15 and September 15, 2026, and January 15, 2027; a date on a weekend or holiday moves to the next business day. Source: IRS.gov, checked October 9, 2026.

This is a savings calculator, not tax advice. It applies the percentage you choose to income minus the expenses and mileage you enter. It does not work out your tax. Ask a tax professional what applies to you.
