How to declare mileage on 2026 Income Tax Return

Mileage declaration on 2026 Income Tax is mandatory for those receiving reimbursements for using personal vehicle for work.

First, understand that mileage reimbursement is not salary. It should be reported in 'Exempt and Non-Taxable Income' form, line 26, as 'Other exempt income'. Total annual amount reimbursed by company must be declared here.

Maintain complete documentation: receipts from all trips, company payment vouchers, and consolidated annual report. Federal Revenue may request proof in detailed audit.

ATTENTION: If you use vehicle 100% for professional purposes and deduct expenses as legal entity or self-employed, treatment is different. Consult accountant to avoid double taxation.

Companies must provide income statement discriminating reimbursement amounts separately from salary. If your company didn't provide it, request urgently before filing deadline.

2026 Tax Return filing deadline will be March to May/2026. Organize your documentation now to avoid last-minute rush.
