Calculating 23% VAT after a discount in Ireland
Whether VAT in Ireland is charged before or after a discount, with a worked example and the difference in what the customer pays.
Key facts
| Place | Ireland |
|---|---|
| Tax | VAT |
| Standard rate on file | 23% |
| Multiply net price by | 1.23 |
| Tax share of a gross price | 18.7% |
| Currency | EUR |
Discount first, then tax
In general the discount reduces the taxable amount, and VAT at 23% is charged on the reduced price. If a 15% discount is applied to a net price, the tax is calculated on the remaining 85%.
Worked example
Here is the calculation with sample figures. Change any number in the Ireland Discount and VAT Calculator to run your own.
| Price | €500.00 |
| Discount (%) | 15% |
| Tax rate (%) | 23% |
| Discount | €75.00 |
|---|---|
| Net amount | €425.00 |
| Tax | €97.75 |
| Total | €522.75 |
Does the order change the total?
Mathematically, applying a percentage discount and a percentage tax gives the same final price in either order. What changes is the tax amount you record and report, and that must reflect the price actually charged.
Vouchers and coupons
Store vouchers, manufacturer coupons and gift cards can each be treated differently. Some reduce the taxable price, others are treated as a form of payment. Check how each type is handled in Ireland before you run a promotion.

- Gross amount
- The amount after tax is added, which is usually what a consumer pays.
- Marginal rate
- The rate applied to the next unit of income. It decides how much of a raise or a deduction you keep.
- Taxable income
- Income left after allowances and deductions, on which the tax rates are applied.
- Zero rate
- A rate of 0% on a taxable supply. Unlike an exemption, the seller can usually still reclaim tax on costs.
Common mistakes to avoid
- Charging tax on the full list price after giving a discount.
- Treating gift cards as discounts.
- Advertising a discount on the gross price but calculating it on the net price.
