Frequently asked questions
How do I add 23% VAT to a net amount?
Gross is net × (1 + rate). At 23% you multiply by 1.23: 1,000 net gives 230 VAT and 1,230 gross. In the calculator choose “Net (without VAT)” and set the percent.
How do I take VAT out of a gross price? Is 23% of gross wrong?
Yes — 23% of gross is a common mistake. VAT is 23/123 of the tax-inclusive price, so net = gross ÷ 1.23. From 1,230 gross you get 1,000 net and 230 tax, not 282.90.
Which VAT rates can I enter?
The default is 23%, Poland’s standard rate. You can type 8%, 5%, 0% or another rate if an invoice or another country needs it. The calculator does not judge which rate is correct for your goods or service.
What is the difference between net, VAT and gross on an invoice?
Net is the amount without tax. VAT is the tax on that amount at the chosen rate. Gross is what the buyer pays. Those three figures must add up; otherwise the invoice is already wrong.
Can I paste this VAT result into a return or ledger?
No. This is a quick educational split, not bookkeeping software. Filing and JPK need real invoices and the statutory rate, not a screenshot from the browser.
