It's that time of year again.
Don't forget that when you submit your returns you can authorise the tax office to donate 0.5% of your tax bill to pay them to authorised charitable organisations of a humanitarian nature (e.g. your local Bombeiros, and a whole lot more).
It won't cost you anything, that 0.5% comes out of what you've got to pay the taxman anyway. All you have to do is enter the relevant NIPC code allocated to your chosen organisation on your tax return.
The list of organisations that can benefit for 2020 tax returns, and their respective NIPC codes, is available at https://info.portaldasfinancas.gov.pt/pt/apoio_contribuinte/IRS/Pages/IRS_entidades_beneficiarias_consignacao.aspx
