Your legal right

You can appeal.
The law guarantees it.

Under Part 40A of the Taxes Consolidation Act 1997, a person who is aggrieved by a Revenue assessment, determination or decision has the right to appeal it to the Tax Appeals Commission — an independent statutory body that decides tax disputes.

You do not need to be a tax adviser. You do not need an accountant. You do not need a solicitor.

A notice of appeal under section 949I must generally be made within 30 days of the date of the notice of assessment or decision. A clearly stated, properly grounded appeal carries far more weight than a phone call to Revenue.

Every citation in your appeal links to irishstatutebook.ie — the official Irish government legislation database — and to the Tax Appeals Commission, so you can verify everything yourself before paying a cent.

SAMPLE APPEAL
14 April 2026
The Tax Appeals Commission
Fitzwilliam Court, Leeson Close
Dublin 2, D02 YW24
Re: Notice of Appeal — Income Tax Assessment
Notice / Assessment Reference: IT-2024-0085432 · Period: Year of Assessment 2023

Dear Commissioners,

I wish to give notice of appeal against the above Revenue assessment in accordance with section 949I of the Taxes Consolidation Act 1997, being a person aggrieved by the assessment under Part 40A of that Act. This notice is made within 30 days of the date of the notice of assessment.①

I appeal on the ground that the assessment is excessive and overstates my liability. The amount assessed of €9,400 does not reflect my actual income for the year of assessment 2023, which has been correctly returned.②

I further appeal on the ground that allowable expenses incurred wholly and exclusively for the purposes of my trade were wrongly disallowed, and that reliefs and credits to which I am entitled were not granted in computing the assessment.③

I respectfully request that the Tax Appeals Commission accept this appeal and that the assessment be reduced or discharged so as to reflect my correct liability, and I confirm I am willing to provide supporting documentation and to attend a hearing if required.

Yours faithfully,

Mary O'Brien
14 Oak Drive, Douglas, Cork

Section 949I — Taxes Consolidation Act 1997 sets out how a notice of appeal is made to the Tax Appeals Commission, generally within 30 days of the assessment or decision. Read how to appeal on taxappeals.ie →
②
Stating clear grounds is what makes an appeal valid — the Commission decides the appeal by reference to the grounds you set out. Saying simply "I disagree" is not enough; the appeal must say why. About the Commission →
③
Each ground is set out separately based on the grounds you select — excessive assessment, disallowed expenses, reliefs not granted, surcharge or penalty disputes. This is what makes the appeal specific to your case, not generic.

Common questions

Everything you need to know

Do I actually have the right to appeal? +
Yes. Under Part 40A of the Taxes Consolidation Act 1997, a person who is aggrieved by a Revenue assessment, determination or decision has the right to appeal it to the Tax Appeals Commission, an independent statutory body. You do not need an accountant or solicitor to lodge an appeal.
How long do I have to appeal? +
30 days from the date on your notice of assessment or decision. A notice of appeal is made under section 949I of the Taxes Consolidation Act 1997. If you are outside the 30 days, the Commission may still accept a late appeal in limited circumstances — see taxappeals.ie.
Is this based on real Irish law? +
Yes. Every citation in your appeal links to irishstatutebook.ie — the official Irish government legislation database maintained by the Attorney General's office — and to the Tax Appeals Commission. You can read the exact legal text and the Commission's own guidance yourself before paying anything.
Will the Commission actually consider my appeal? +
Yes. The Tax Appeals Commission is an independent statutory body that decides appeals on their merits. A valid appeal must set out clear grounds — this is exactly what your document does. The Commission decides the appeal by reference to the grounds you state, which is why a properly structured notice of appeal matters.
Is there a fee to lodge an appeal? +
No. There is no fee to lodge an appeal with the Tax Appeals Commission. Our €9.99 is only for drafting and delivering your notice of appeal as a clean PDF. We are not affiliated with the Commission or with Revenue, and the €9.99 is paid only to TaxAppeal.ie.
What if the Commission decides against me? +
A determination of the Tax Appeals Commission may be appealed to the High Court on a point of law. The Commission's website explains the process and the time limits that apply after a determination is issued.
What if I'm not satisfied with the document? +
We offer a full money-back guarantee. If the notice of appeal is not what you needed, contact us within 48 hours of purchase and we will refund you in full — no questions asked. See our Refund Policy.
Is this legal or tax advice? +
No. TaxAppeal.ie is a document-drafting tool. It correctly references publicly available Irish tax-appeal legislation, but this is not legal or tax advice, we are not solicitors or tax advisers, and we are not affiliated with the Revenue Commissioners or the Tax Appeals Commission. For complex or high-value disputes we recommend consulting a qualified tax adviser or solicitor.
