What is IRS consignment?

The IRS consignment consists in the donation of 0.5% of the tax owed to the State, by the taxpayers, to an institution. The institutions to whom the IRS can be consigned are:

  • Environmental NGOs, according to Law n.º35/98, changed by Law n.º 36/2021; 

The list of entities that are able to benefit from the tax consignment is published by the Portuguese Tax Office [Autoridade Tributária e Aduaneira (AT)] until the starting day of the period for filing the tax return, and you can check it here

How can you consign your IRS?

You can carry out your IRS consignment before the beginning of the period for filing your tax return (until March 31st), or after that, in the moment of filing it.

  • For the manual filing of the tax return, you can carry out the consignment in box 11 of the cover of the IRS Model 3 declaration;
  • For the automatic tax return, the consignment is made in the "Pre-liquidation" section.

Why consign the IRS?

Contrary to what one might think, consigning the IRS does not affect the amount the taxpayer has to receive (tax refund) or pay. The amount donated to the institution is deducted from the net amount collected, i.e. the total amount of tax collected by the State. 

Consigning the IRS does not affect the amount the taxpayer has to receive (tax refund) or pay. The amount donated to the institution is deducted from the net amount collected, i.e. the total amount of tax collected by the State. 

For example, if a taxpayer who has a total net income of €2,000 and is owed €150 of tax refund decides to donate 0.5% to an institution, they will still receive the €150 refund. The difference is for the State, which, instead of collecting €2000, will keep €1990 and donate €10 (0.5%) to the chosen institution.

This is, therefore, an opportunity for everyone to show more solidarity and help those in need. In this case, helping actually doesn't cost a thing.
