Medical expenses

You can claim tax relief on many qualifying health expenses at the standard income tax rate, currently 20%. This can include GP visits, consultant fees, prescriptions, physiotherapy when qualifying, and certain dental treatments. You cannot claim for amounts already reimbursed by an insurer or another body.

Keep receipts and claim through the Health Expenses section in myAccount. If your family paid bills across several people, the person who actually paid the expense generally makes the claim.

Remote working relief

If you work from home and your employer does not fully reimburse your costs, you may be able to claim relief for a portion of electricity, heat and broadband. Revenue's remote working relief is based on the number of days you worked from home and the relevant household bills.

If your employer pays a tax-free remote working allowance, deduct that payment before claiming any further relief.

Tuition fees

Tax relief may be available on qualifying third-level tuition fees. The relief is at the standard rate and applies only to qualifying fees, not registration fees, exam fees or administration charges. Revenue also applies disregard amounts, so you may not get relief on every euro paid.

Flat-rate expenses

Some employments have agreed flat-rate expenses for typical work costs, such as uniforms or tools. You do not need to prove the exact cost, but your job must match the Revenue-approved category. It is worth checking if your occupation appears on Revenue's list.

Revenue claim process

For PAYE workers, the route depends on the tax year and the credit or relief. For a current-year claim that Revenue allows in-year, use Manage your tax for the current year in PAYE Services. For a completed previous tax year, use Review your tax for the previous 4 years, select the year and complete the Income Tax Return. Check Revenue's guidance for the particular claim.

You can generally claim back for the previous four years, so do not only check the current year.

A credit reduces tax euro-for-euro. A relief usually reduces the income that is taxed or gives relief at a particular rate. That is why two claims with the same expense amount can produce different refunds.

What this means in real life

For a PAYE worker, an eligible tax credit or relief can reduce the income tax due for a year or lead Revenue to refund tax already overpaid. It does not usually reduce USC or PRSI, and it cannot create a refund greater than the relevant tax liability. Different items also work in different ways. Health expenses may be relieved at the standard rate, remote-working relief is based on qualifying costs and workdays, and tuition-fee relief has its own exclusions and thresholds. A person may need receipts or other records if Revenue requests support for a claim. The practical effect can appear through updated payroll credits or through an end-of-year review. The tax credits guide explains how credits affect PAYE generally. The Irish Salary Calculator uses only the standard credits stated in its assumptions, so these additional reliefs are not automatically included.
