Key Personal Tax Reliefs Updated in Budget 2027

Budget 2027 places targeted emphasis on reducing household expenditure through statutory tax relief updates. The most prominent measure is the increase in the Rent Tax Credit under Section 473B of the Taxes Consolidation Act 1997, raising the maximum annual deduction to €1,250 for single taxpayers and €2,500 for married couples or civil partners paying qualifying rent.

This relief applies to tenants living in private residential accommodation, rent-a-room arrangements, and parents funding qualifying student accommodation. Tenants who have rented continuously since 2022 can claim up to €3,000 in backdated rent tax credits across the four open years (2022 - 2025), provided their 2022 claim is submitted before the end-of-year statutory deadline.

In addition to rent relief, core employee tax allowances have been expanded to protect take-home earnings, ensuring that workers across lower and middle income brackets retain a greater portion of their salary under revised PAYE and USC schedules.

• Single Tenant Relief: €1,250 for 2027; historical €1,000 (2024/2025) and €500 (2022/2023).
• Married Tenant Relief: €2,500 for 2027; historical €2,000 (2024/2025) and €1,000 (2022/2023).
• Broad Tenancy Coverage: Covers private tenancies, digs, and student accommodation registered with the RTB.

Medical and Non-Routine Dental Expense Tax Relief

While Budget Day frequently updates headline bands, existing health expense relief remains one of the most lucrative and underclaimed tax reliefs in Ireland. Under Section 469 of the Taxes Consolidation Act 1997, Irish taxpayers can claim 20% tax back on virtually all qualifying medical expenses not reimbursed by private health insurance or public schemes.

Qualifying health expenses include GP appointments, prescription medications, hospital treatment, consultant visits, physiotherapy, psychotherapy, diagnostic tests, and qualifying maternity care. Non-routine dental treatments - such as crowns, root canals, braces, and wisdom tooth extractions - are also eligible at 20% when certified on a Med 2 form by your dental surgeon.

Health expense relief is not restricted to your own costs; you can claim 20% relief on qualifying medical bills paid on behalf of your spouse, children, or dependent relatives. By aggregating medical receipts across 2022, 2023, 2024, and 2025, families routinely unlock refunds of €800 to €2,500 from Revenue.

• 20% Standard Relief: Reclaim €20 for every €100 spent on qualifying doctor and medical bills.
• Med 2 Dental Relief: 20% tax back on orthodontic treatment, crowns, root canals, and surgical extractions.
• Family Aggregation: Claim relief on behalf of children, dependent relatives, and spouses.

Flat Rate Job Expenses for Trade and Professional Workers

Flat rate expenses are agreed statutory deductions negotiated between Revenue and trade unions for specific employment categories. They are designed to cover the cost of laundering work uniforms, purchasing safety equipment, trade tools, and professional materials.

Unlike general expenses, flat rate expenses do not require you to retain individual shop receipts. If you work in a qualifying profession - such as nursing, teaching, carpentry, plumbing, retail, or hospitality - you are automatically entitled to deduct the flat-rate allowance directly against your gross taxable income for every year you held the role.

Nurses can deduct up to €733 annually; primary teachers can claim €518; construction workers can claim between €100 and €220; and hotel and retail staff can claim up to €160 per year. Because employers rarely add these allowances to payroll automatically, thousands of workers overpay tax every year until a retrospective review is submitted.

• No Receipts Required: Fixed statutory deductions approved by Revenue for qualifying professions.
• Common Allowances: Nurses (€733/yr), Teachers (€518/yr), Construction Workers (up to €220/yr).
• Four-Year Multiplier: Claim four years of allowances simultaneously for a substantial cash refund.

How to Combine Past Reliefs into One Large Cash Refund

Under Ireland’s four-year statutory rule (s.865 TCA 1997), you do not have to claim reliefs one by one or wait for individual tax years to conclude. You can submit a consolidated review covering 2022, 2023, 2024, and 2025 in a single claim.

When MyTaxRebate conducts your four-year review, we combine your rent tax credits, medical and dental receipts, flat rate job allowances, and remote working deductions across all four open years. This cumulative reconciliation frequently produces a combined cash refund of over €1,080 deposited directly into your bank account.

The critical factor is timing: all claims for the 2022 tax year must be submitted to Revenue before 31 December 2026. Submitting your application now guarantees that your 2022 entitlements are protected from permanent forfeiture.

• Consolidated Multi-Year Claim: Reclaim 2022, 2023, 2024, and 2025 in one seamless process.
• December 31st Deadline: 2022 tax relief permanently expires at the end of this calendar year.
• No Win, No Fee Guarantee: Zero upfront cost and zero fee if no refund is secured.
