Complete Guide
PAYE and self-assessment are different
A PAYE employee may complete an end-of-year review through myAccount, while a self-assessed taxpayer may need Form 11 on ROS. Identify your correct route before gathering paperwork.
Start with Revenue records
Employer-reported pay and statutory deductions can be reviewed in myAccount. Cross-check those figures with your own payslips, self-employment income and investment records.
Claim only lawful reliefs
Tax credits, health expenses, pensions and remote-working claims have different eligibility requirements. Receipts and supporting calculations should be accurate and retained.
Use the correct year and deadline
Returns and payments are year-specific. For example, Revenue published distinct 2026 dates for the 2025 Form 11 filing; do not carry those dates forward automatically.
Protect your personal records
Revenue accounts, tax reference numbers and bank details belong in private records, not public or collaboratively shared checklist notes.
Review the result after filing
A Statement of Liability or self-assessment computation can show a balance due, a refund or no adjustment. Follow the payment or correction steps indicated by Revenue.
Frequently asked questions
Does every employee need a Form 11?
No. Many PAYE workers review their taxes through myAccount; Form 11 is generally for people subject to self-assessment.
Is a preliminary year-end calculation final?
Not necessarily. A PAYE Income Tax Return and subsequent Statement of Liability confirm the result after relevant income and reliefs are reviewed.
Should I use one deadline for every year?
No. Revenue publishes specific Pay and File and ROS extension dates for each filing year; confirm the applicable year before submission.
