Expert Tips forMaximum Claims
Professional guidance to ensure compliance and maximize your legitimate expense claims
Keep Detailed Records
Maintain a logbook with dates, destinations, business purpose, and odometer readings. Digital records are acceptable but must be backed up. Retain all records for at least 6 years as required by Revenue.
Know Your Engine Category
Check your vehicle registration document for engine size. Fully electric vehicles qualify for Category E rates (same as Category B). Hybrid vehicles use the category matching their actual engine CC. Motorcycles use a separate 2-band system (M1-M4).
Time Your Dublin Trips
For Dublin overnight stays, the civil service arrangement is vouched accommodation (actual receipted cost up to a €205.53 cap) plus a separate €46.17 meal allowance. Keep receipts for all meals and accommodation.
8km Rule for Subsistence
You must be at least 8km from both your home and your normal place of work to claim subsistence allowances. GPS logs or route planners can help prove this distance if queried by Revenue.
Progressive Mileage Bands
Rates change as your annual mileage increases. Track cumulative kilometers carefully — our platform does this automatically for every vehicle, and you can set opening year-to-date km when joining mid-year so the bands stay correct from day one.
Commute Deduction
Your normal commute is not a business journey. If a business trip starts from home, Revenue's "lesser of" rule means the claim is based on the shorter of home-to-destination or office-to-destination. Our full platform applies this automatically.
