Step 1: review the tax position position position Position
The first step is identifying whether you are owed a refund and how much. Under s.865 TCA 1997, you are entitled to a refund of any income tax overpaid within the past four years. When you complete MyTaxRebate's online application, we access your Revenue records through our registered agent connection and review your employment history, tax credit certificates, and any qualifying expenses for each of the four available years. We calculate the refund due for each year and present you with a clear breakdown before we submit anything.
Step 2: Gather Your Records
For most claims, you will need to provide: confirmation of your PPS number, payslips or P60 documents for each available year (or employer confirmation where payslips are unavailable), and any receipts or records supporting your expense claims. Medical expenses require receipts from GPs, hospitals, pharmacies, consultants, and dentists - or pharmacy annual statements if original receipts have been lost. Flat-rate employment expense claims require only confirmation of your occupation. Remote working claims require a count of qualifying home-working days and utility bill information.

Step 5: Refund Payment
Once Revenue approves the refund, they issue payment within 2 to 3 working days by electronic funds transfer (EFT) if your bank account IBAN is on record. Where no bank details are registered, Revenue issues a cheque by post, which adds 5 to 7 days. MyTaxRebate notifies you immediately when the refund is approved and confirmed. Our fee is deducted at that point - you pay nothing until Revenue has approved the refund.
Documentation You Need to Submit a Claim
A successful tax back claim under s.865 TCA 1997 requires specific documentation depending on the entitlements being claimed. For medical expense relief: receipts from GPs, consultants, dentists, pharmacies, or hospitals for qualifying non-reimbursed expenses. For flat-rate employment expenses: no receipts required - the allowance applies by occupation. For remote working relief: a record of qualifying work-from-home days (employer confirmation or personal log). For additional credits (Age, SPCCC, Home Carer): confirmation of qualifying circumstances. MyTaxRebate assists with the documentation process and advises on exactly what Revenue requires for each component of the claim.
Step-by-Step: How a Claim Progresses
Once you complete the MyTaxRebate application and provide the relevant documentation, the claim progresses through the following stages: (1) MyTaxRebate reviews your four-year tax position and calculates the refund for each year; (2) We pre-validate the claim against Revenue's rules; (3) We submit the claim to Revenue through the agent portal as your appointed tax agent; (4) Revenue processes the claim within 5 to 15 working days; (5) If Revenue issues a query, we respond on your behalf; (6) Revenue issues the refund by EFT to your bank account (2 to 3 working days after approval). The full process typically takes 3 to 4 weeks from submission to payment.
The Four-Year Deadline and Why Acting Now Matters
Under s.865 TCA 1997, the right to claim tax back for a given year expires four years after the end of that year. The 2022 deadline closes 31 December 2026. There is no exception. Workers who defer their review risk losing the 2022 year permanently if they delay past this date. Submitting a comprehensive four-year claim now - covering 2022, 2023, 2024, and 2025 - ensures all available entitlements are captured before any deadline expires.
One of the most important steps in claiming tax back in Ireland efficiently is to gather your supporting documentation before starting the claim process in your Revenue record. For medical expenses, this means collecting receipts or downloading records from your GP or pharmacy. For tuition fees, you need the official receipt from the college or university. For flat-rate expenses, no receipts are needed - just confirmation from Revenue's list that your occupation qualifies. Having everything ready before logging into your Revenue record ensures the claim is submitted accurately and reduces the risk of needing to amend it later.
Once submitted, Revenue's system processes most claims within five working days and pays the refund directly to your registered bank account. If you have not registered a bank account in your Revenue record, Revenue issues a cheque which takes longer to arrive. Registering a bank account is straightforward through the your Revenue record portal and ensures you receive future refunds as quickly as possible. Under section 865 TCA 1997, remember that you can submit claims for all four open tax years in one session, so it is worth reviewing all available years rather than just the most recent one.

Tax Scenarios
Scenario 1: Simple Four-Year Claim
A retail worker completed MyTaxRebate's application on a Monday, provided her P60s and a pharmacy annual statement showing €1,680 in qualifying costs. We reviewed her four-year position, identified her retail flat-rate allowance for each year, and submitted the full claim by Wednesday. Revenue processed it in 12 working days. She received €1,420 in her bank account on a Friday - 18 days after starting the application.
Scenario 2: Claim With Supporting Documents
A nurse had €3,400 in medical expenses across four years and claimed her nursing flat-rate allowance. Her documents included pharmacy statements for 2022 - 2024, original receipts for 2025, and her P60 for each year. MyTaxRebate submitted the complete claim. Revenue processed it in 14 working days and issued a refund of €2,280 directly to her bank account via EFT.
Scenario 3: Claim Queried by Revenue
Revenue selected a claim for additional verification when a worker submitted for €2,800 in medical expenses across four years. Revenue requested the original receipts for the two largest items. MyTaxRebate liaised with Revenue's compliance team, provided the supporting documentation, and the claim was approved in full within 28 days of the original submission. The refund of €2,240 was issued without any reduction.
Common Mistakes To Avoid
- ✗Starting without your PPS number confirmed: Revenue cannot process any claim without a valid PPS number. Confirm your PPS number before starting the application to avoid delays.
- ✗Not gathering records for all four years at once: Starting a claim and then discovering mid-process that records for earlier years are missing adds days to the timeline. Gather payslips, P60s, and expense records for all four available years before starting.
- ✗Submitting without checking expense receipts: Revenue may request original receipts for expense claims during the processing stage. Ensure all receipts are available (or that pharmacy/GP statements have been obtained) before submission to avoid a compliance query causing delays.
- ✗Not updating bank account details with Revenue: If Revenue holds an incorrect or closed IBAN, the EFT will fail and Revenue will issue a cheque instead, adding 5 - 10 days to the process. Update your bank details before submitting.
- ✗Contacting Revenue directly after agent submission: Once MyTaxRebate has submitted as your agent, Revenue's primary point of contact is us, not you. Direct contact from the claimant after agent submission can complicate processing. Allow MyTaxRebate to manage all Revenue communications.

Frequently Asked Questions
How do I claim tax back in Ireland step by step?
MyTaxRebate handles the full process on your behalf. You provide your personal details and relevant records, and we identify your complete entitlement across the four-year backdating window under section 865 TCA 1997. We calculate your exact refund and submit directly to Revenue - you do not need to contact Revenue or navigate any Government portal. Once Revenue approves the claim, the refund is typically paid to your bank account within five working days.
What documents do I need to claim tax back?
The documents required depend on what you are claiming. For a general credit review: your PPS number and P60 or payslips for each available year. For medical expenses: receipts from GPs, hospitals, pharmacies, and dentists, or annual statements from your pharmacy if receipts are missing. For flat-rate employment expenses: only confirmation of your occupation (no receipts needed). For remote working: a record of home-working days and utility bills for the relevant years. MyTaxRebate will tell you exactly what is needed for your specific claim.
How long does the tax back claim process take?
The full process typically takes 3 to 4 weeks from when you complete our application to receiving your refund. MyTaxRebate completes the review and submission within 1 to 3 working days of receiving your application. Revenue processes the claim within 5 to 15 working days. Revenue then issues the refund within 2 to 3 working days by electronic transfer. During Revenue peak periods (January - February and October - November), the Revenue processing phase may take up to 6 weeks.
Do I need to contact Revenue myself when claiming tax back?
When MyTaxRebate handles your claim, you do not need to contact Revenue at any stage. We submit as your appointed tax agent, manage all communications with Revenue, respond to any queries, and notify you when the refund is approved. Revenue processes the claim through our agent portal. The only reason to contact Revenue directly would be if you chose to submit independently through your Revenue record - which bypasses the agent process and means Revenue will deal with you rather than us.
How far back can I claim tax back through the step-by-step process?
Under s.865 TCA 1997, the step-by-step claim process covers up to four tax years. In 2025, the available years are 2022, 2023, 2024, and 2025. MyTaxRebate reviews and submits for all four years simultaneously in a single comprehensive claim. This is the most efficient approach: it requires the same effort as a single-year claim but recovers up to four times as much. The 2022 deadline is 31 December 2026 - act now to ensure this year is included.
