Details most tax authorities expect
A valid tax invoice usually shows the seller name, address and tax registration number, the buyer details, a unique sequential invoice number, the invoice date, a clear description of each item, quantity and unit price, the rate applied and the amount of tax, and the total due. Exact requirements differ, so confirm the list for Portugal.
Worked example
Here is the calculation with sample figures. Change any number in the Portugal Invoice VAT Calculator to run your own.
| Quantity | 10 |
| Unit price (net) | €50.00 |
| Tax rate (%) | 23% |
| Net amount | €500.00 |
|---|---|
| Tax | €115.00 |
| Total | €615.00 |
Net, tax and gross on every invoice
Show the net amount, the VAT at 23% and the gross total separately. Customers who are registered need that breakdown to reclaim the tax, and it makes your own reconciliation straightforward.
Credit notes
If you need to correct an invoice, issue a credit note that references the original rather than editing or deleting it. The credit note reverses the tax as well as the net amount.
Quick reference at 23%
Common amounts in Portugal, worked both ways: adding tax to a net price, and extracting it from a price that already includes tax.
