The Polish Tax Authorities require businesses established outside of the EU and having a VAT registration in Poland to appoint a fiscal representative in Poland. The fiscal representative can be an individual or a company, such as Sovos. The fiscal representative is jointly and severally liable with the taxpayer for the tax liability, which the fiscal representative settles on behalf of and for the benefit of that taxpayer in Poland.
It is worth noting that, since 23 February 2021, taxpayers established in Norway or Great Britain have not been obliged to appoint a fiscal representative when operating in Poland. The companies established in both Norway and Great Britain can register directly for VAT purposes in Poland. This entails that the legal representative of the company can sign the registration form without any involvement from the Polish established Company or an individual acting in the capacity of a fiscal representative.
An EU business is not required to appoint a fiscal representative to register for VAT in Poland, but it may choose to do so.
