Monthly tax obligations for companies in Portugal

Running a company in Portugal means meeting a set of tax obligations on fixed deadlines. Missing them can lead to fines, so it is worth knowing the calendar.

The most common include filing the periodic VAT (IVA) return, paying the VAT due, IRS withholding tax and Social Security contributions.

Whether VAT is filed monthly or quarterly depends on the company’s turnover. The key dates for each month are shown in the tax calendar on our homepage.

At Triconta Digital we track these deadlines for you and remind you in good time, so you never have to worry about a forgotten date.
