Configurable mileage rates

Tax Deduction Estimate — use this kind for an IRS-style standard mileage rate. Reports labeled with this kind are intended for personal tax preparation reference. The app defaults to $0.70/mi; update it to match the IRS rate for your tax year.

Employer Reimbursement — use this kind if your employer reimburses at a fixed rate per mile. Reports using this rate show what you might submit to your employer.

Custom — any other per-mile rate. Useful for state-level rates, client billing, or your own bookkeeping.

Open **More → Mileage Rates** (or Settings → Per-Mile Rates).

Choose the estimate type (Tax deduction, Employer reimbursement, or Custom), enter the $/mi amount, an optional label, and Effective From, then save.

Saving creates a new effective period; earlier open-ended rates for that type are closed the day before.

Pick the estimate type on the Mileage Rates screen. Reports and drive estimates use the rate whose effective dates cover each drive’s start date.

Tax deduction and employer kinds fall back to the seeded IRS business rate when no stored period covers the day. Custom rates do not — set a custom amount before relying on those estimates.

MileLedger multiplies **displayed miles** (1 decimal, truncated) by the rate, then **truncates to cents** — it never rounds mileage dollar estimates up. Example: 3.5 mi × $0.77 → $2.695 → **$2.69**.

Use History on the Mileage Rates screen (long-press / context menu) to reuse a period in the form or delete it.

Deleting a period does not change past trips; future estimates use the next matching rate for that type.
