Preparation and Submission of the OSS Declaration
Progress Holding is your local finance department in Poland, operating on an outsourcing basis for international companies. We build direct interaction with the client’s headquarters, coordinate financial operations on the ground, and simplify the management of the Polish subsidiary. Creating an in-house finance department from the very first days of operation in a new market is often impractical and highly expensive. Therefore, cooperating with Progress Holding greatly simplifies the task of relocating a company to the Polish market.
Progress Holding has 22 years of experience supporting foreign entrepreneurs doing business in Poland. We become your local financial unit in Poland, ensuring the execution of all functions related to finance, accounting, and regulatory compliance necessary for launching and successfully operating your business in the country.
One of the key tasks for companies selling goods to clients in different European Union countries is accurate VAT accounting. Without the OSS system, you would have to register as a VAT payer in every country where transactions occur, which means multiple layers of bureaucracy, different languages, and a constant risk of errors. The OSS (One-Stop-Shop) system solves this problem by allowing centralized VAT accounting through a single EU country.
However, even this simplified system requires precise determination of transaction volume, accurate completion of the declaration, and timely tax payment. And this is where our 22 years of experience working with foreign companies becomes your main advantage. We speak your language: we provide full support in English, Ukrainian, and Russian.
What exactly is included in the “Preparation and Submission of the OSS Declaration” service from Progress Holding?
We don’t just “fill out a form” — we ensure full compliance with European and Polish regulations so your business operates legally and penalty-free in the EU. You pay for a concrete result, which includes:
- Analysis and determination of transaction volume: Precise classification of all your transactions within the EU — supply of goods, provision of services, identification of recipient countries, and applicable VAT rates.
- Registration in the OSS system: Professional preparation and submission of the application for OSS registration in Poland (or assistance with registration via a specialized online portal), including communication with tax authorities during verification.
- Preparation of the OSS declaration: Collection of all data on cross-border transactions for the reporting period, calculation of VAT amounts for each EU country, and preparation of a detailed declaration with a full description of operations.
- Accurate completion of all fields: Filling in all necessary declaration fields with information on transaction types, recipient countries, net amounts, and calculated VAT — which is critical for accuracy and avoiding inquiries from tax authorities.
- Electronic submission of the declaration: Submission of the completed OSS declaration to the relevant tax authority in Poland via the online platform within the established deadlines (quarterly, by the 20th day of the month following the reporting quarter).
- VAT payment control: Calculation of the final VAT amount due and timely notification of the need for payment to avoid interest and penalties.
- Coordination with headquarters: We build transparent reporting and communication between your Polish subsidiary and the headquarters, ensuring unified and clear financial management.

Why do foreign investors choose Progress Holding for working with the OSS declaration?
We don’t just “submit reports” — we create comfortable and secure conditions for foreign businesses in Poland and the EU, relying on our 22 years of experience:
- Full support in English, Ukrainian, and Russian. Communicate with us in the way that is most convenient for you. We eliminate any misunderstandings with Polish and European tax authorities — we handle all applications, documents, and explanations on your behalf.
- 22 years of expertise in working with foreign companies. We have been on the market for a long time and work closely with international businesses conducting cross-border operations. We perfectly understand the specifics of European VAT, the OSS system, and the requirements that Polish and European regulators impose specifically on non-residents.
- Coordination with the client’s headquarters. We structure our interaction so that your headquarters receives transparent and timely information about the financial operations of the Polish subsidiary.
- Representation of your interests. We personally interact with Polish tax authorities on your behalf. You don’t need to navigate European bureaucracy or master online platforms on your own.

- Clear explanations of complex issues. We explain the requirements of the OSS system, European VAT, and cross-border transactions in simple, accessible language – without professional jargon or “European bureaucratic logic.”
- Dedicated specialist. You are assigned a dedicated expert who knows your entire business history and resolves absolutely all issues – from OSS registration to the submission of every quarterly declaration.
- Understanding of the mentality and needs of foreigners. We know the difficulties foreign investors face in Poland when working with the EU, and we structure our work so that you feel just as confident as local entrepreneurs.
Don’t put off preparing the OSS declaration until later!
In the Polish tax system, delay can be costly — especially for foreign businesses, where any error attracts heightened attention from regulatory authorities. Entrust the preparation and work to professionals who know the local specifics inside out and have years of experience working specifically with foreign clients.
A late OSS declaration or errors in cross-border transactions mean direct fines, interest charges, and the risk of tax issues not only in Poland but in other EU countries as well.
Contact us for a consultation in English, Ukrainian, or Russian! We will assess the volume of your cross-border operations, calculate the cost, and take all OSS-related bureaucracy off your hands — so you can calmly focus on growing your business in the EU from Poland.
