Tax return deadlines 2026: what freelancers must not miss
Missing a filing deadline turns a routine obligation into penalties and interest. The dates differ for personal versus corporate returns, and for self-filers versus accountant-filed returns — here is how to keep them straight.
Personal vs corporate
Your personal income tax return (for you as director) and your company’s corporate tax return are separate filings with separate deadlines. A one-person company owner has both to keep track of.
Self-filed vs via an accountant
Returns filed on paper, filed yourself online, or filed by a mandated accountant typically carry different deadlines, with the accountant route usually giving more time. If a professional files for you, confirm the applicable date rather than assuming the earliest one.
- Personal income tax and corporate tax are separate deadlines
- Paper, self-online and accountant-filed dates typically differ
- The corporate deadline is tied to your financial-year close
- Late filing means penalties and interest — calendar them early
