Portugal: Changes to One Stop-Shop scheme and VAT filing and payment deadlines

One-Stop Shop scheme

Following publication of special regimes in Annex I of Portugal’s Value-Added Tax (VAT) Law 47/2020 of 24 August 2020 (due to enter into force on 1 July 2021), Tax Circular 30233 was published on 19 April 2021 outlining further information on the One-Stop Shop scheme (OSS) (Balcão Único).

Law 47/2020 approved special regimes applicable to taxable persons who provide services to persons who are not taxable persons, that carry out distance sales and certain internal transfers of goods. To facilitate compliance of the obligations associated with these operations, the OSS was created, with a broader scope comprising three different regimes. Accordingly, Tax Circular 30233 outlines the following:

  • Pre-registration: Taxable persons who, from 1 July 2021, intend to apply for any of the special regimes set forth under Law 47/2020, can register with the OSS through electronic means until 30 June 2021.

  • Update of data in the existing register

    • Taxable persons who, at 30 June 2021, are covered by the Mini One-Stop Shop (MOSS) already in force (introduced by Decree-Law 158/2014), will be covered directly by the new OSS special regime as of 1 July 2021.

    • If there are differences regarding the scope of the schemes, taxable persons must update the data in the existing register by 30 June 2021, using electronic means.

  • Additionally, the underlying Tax Circular outlines that further administrative guidelines on the new special regimes will be published shortly.
