Payment of tax
Portugal uses a pay-as-you-earn (PAYE) system, adjusted by annual tax return filing. Additional payments or refunds are made based on the tax returns filed.
For Portuguese income tax returns electronically submitted by the legal deadline (i.e. by 30 June of the year following the one the income relates to), the Portuguese tax authorities should issue the tax assessment by 31 July of that year and the respective tax due, if applicable, should be paid by 31 August. If the Portuguese tax authorities do not issue the tax assessment by 31 July, the tax liability should be paid within one month from the issue of the referred tax assessment.
