The three-step method

Start with the net price, the amount before tax. Multiply it by 0.23 to get the VAT. Add that tax to the net price, or simply multiply the net price by 1.23 in one step. The result is the gross price your customer pays.

Worked example

Here is the calculation with sample figures. Change any number in the Ireland VAT Calculator to run your own.

Tax rate (%)23%
Tax€23.00
Total€123.00

Rounding: line by line or on the total?

If an invoice has several lines, calculating tax per line and then adding can produce a total that differs by a cent or two from calculating tax on the invoice total. Pick one method, apply it consistently, and check what your local rules expect. Accounting software in Ireland usually lets you choose.

When the price already includes tax

Retail prices shown to consumers often already include VAT. In that case you are not adding tax but extracting it, which needs a different formula. The reverse calculator handles that case.

How Ireland compares

Standard rates on file for other countries. A difference of a few points matters most on high-value purchases and on cross-border sales.

Frequently asked questions

What number do I multiply by to add VAT in Ireland?

Multiply the net price by 1.23. That gives the price including 23% VAT.

Is VAT added before or after a discount?

Normally after: the discount reduces the taxable amount first, and tax is charged on what the customer actually pays.
