Ireland Tax Calculator (2026) — Add or Reverse Tax
Ireland charges a 23% VAT, a 12.5% corporate tax rate, and a 48% top personal income tax rate.
How to use this calculator:
- Purchase mode — add VAT to a pre-tax price, or reverse a tax-included total to find the pre-tax price and exact tax paid.
- Profit / salary modes — enter an amount to see the corporate tax owed or a ceiling estimate of personal tax at the top marginal rate.
Understanding Ireland's Tax System
Ireland levies VAT at a standard rate of 23%. Its statutory corporate income tax rate is 12.5%, below the 23.58% global average. The top personal income tax rate is 48%.
15% corporate rate applies to large multinationals under Pillar Two.

Why Reverse Tax Calculation Matters
Receipts and invoices usually show only the tax-included total, so separating revenue from tax collected — for bookkeeping or cross-border comparisons — means working backward from that total. Dividing by (1 + rate) isn't the same as subtracting the rate, which is why selecting "Reverse" in the purchase-mode calculator above handles it exactly.
History & Context
Ireland phased its corporate tax rate down from 40% to 12.5% between 1996 and 2003, a deliberate strategy that attracted major US multinationals seeking a low-tax EU base. The controversial 'Double Irish' profit-shifting structure, which let companies route profits through Irish subsidiaries to reduce effective tax well below the 12.5% headline rate, was phased out entirely by 2020.
Under the OECD's Pillar Two global minimum tax, Ireland now collects a top-up tax (from 2024) to ensure large multinationals pay an effective 15% rate — while Ireland keeps its 12.5% headline rate for smaller businesses outside Pillar Two's scope, creating a genuine two-tier system based on company size.
Business Use Case
A large multinational with over €750 million in global revenue operating in Ireland now effectively pays 15% (12.5% plus a top-up tax) under Pillar Two rules, while a smaller Irish business outside that revenue threshold continues to pay the traditional 12.5% headline rate — the same country, two different effective corporate tax regimes based purely on company size.
Real-World Examples
VAT on a purchase
A €1,000.00 purchase in Ireland at 23%:
- Tax: €1,000.00 × 23% = €230.00
- Total: €1,230.00
Corporate tax on profit
€1,000.00 in company profit in Ireland at 12.5%:
- Tax: €1,000.00 × 12.5% = €125.00
- After-tax profit: €875.00
Extracting VAT from a receipt total (reverse)
A receipt shows a €1,499.00 tax-included total in Ireland at 23%:
- Pre-tax price: €1,499.00 ÷ (1 + 23%) = €1,218.70
- VAT: €1,499.00 − €1,218.70 = €280.30
