Year-End Tax Checklist for Irish Sole Traders

The Irish tax year for sole traders aligns with the calendar year. Use this checklist in Q4 to minimise your bill and avoid the October rush.

Ensure every business transaction is categorised, bank accounts are reconciled, and outstanding invoices are chased. Gaps in records lead to overpaid tax or Revenue queries.

Review uncategorised expenses, home office claims, mileage logs, and professional fees. Make pension contributions before 31 October to claim relief in the current year.

Purchases of computers, tools, and vehicles may qualify for capital allowances. Timing large purchases before year-end can accelerate relief — our Tax Agent calculates the optimal approach.

Sole traders pay preliminary tax for the following year based on current-year liability. Underestimating triggers interest; overpaying ties up cash. FinnAccountings estimates your Form 11 liability in real time.

Form 11 and balance of tax are due 31 October (mid-November if filing and paying via ROS). Mark Revenue payment dates and set reminders — our Compliance Agent does this automatically.
