Common Self-Assessment mistakes to avoid
Missing the filing deadline triggers automatic penalties from Revenue. If you file the paper tax return early, before 31 August, Revenue will complete the self-assessment section on your behalf.
Forgetting to declare all income sources is a serious error. Revenue can cross-reference information from multiple sources.
Overlooking allowable expenses costs you money in unnecessary tax payments. Keep detailed records of all business-related costs.
Record keeping requirements
Proper records must be maintained for six years plus the current year. This includes all invoices, receipts, and bank statements.
Digital storage is acceptable provided records remain accessible and readable. Cloud storage offers secure backup and easy retrieval.
Organised filing systems save hours during tax return preparation. Category folders help locate specific documents quickly.
Deadlines and payment options
Understanding key dates prevents costly penalties and interest charges. Mark these important deadlines in your calendar system.
Deadline Type | Date | Purpose | Registration |

New self-assessment registration | 5 October | Registration | New self-assessment registration |

Start preparing for next year’s self assessment tax return immediately. Regular bookkeeping throughout the year reduces year-end stress.
Set up automatic systems for expense tracking and income recording. Monthly reconciliations catch errors before they become problems.
