NederlandsThe Mews Compliance Suite helps Polish properties meet their accommodation tax and e-invoicing obligations. In Poland, it includes Tax Automation, Tax Intelligence, and e-invoicing through KSeF, Poland's national e-invoicing system. You purchase the Compliance Suite once from the Mews Marketplace and then choose which features and integrations to use.
In this article, you can learn about:
Tax Intelligence
Tax Intelligence is a dashboard and report in Mews Operations under the main menu > Finance > Tax Intelligence. It shows the local or spa fee you collected and the exemptions you applied, and gathers the data you need for your declaration in a document you can export.
- Dashboard: person nights, both taxable and exempt, a breakdown of tax collected by rate, and a month-by-month trend.
- Monthly report: tax collected, occupancy, including room nights, person nights, and arrivals, and accommodation revenue split into taxable and exempt.
- Exemption log: exempt stays, guests, and person nights grouped by reason, with a line for each guest.
- Flexible and exportable: filter by week, month, quarter, or a custom period, and export to PDF or Excel.
Note: Tax Intelligence exports the data but does not submit your declaration. The report only includes stays where all bills are closed. Each stay is counted in the month of check-out.
You can watch a short overview in the video Tax Intelligence in Mews and learn more in our help article Introducing Tax Automation and Tax Intelligence.
Tax Automation
In Poland, the local fee, the opłata miejscowa, and the spa fee, the opłata uzdrowiskowa, may be introduced and set by each municipality, the gmina, subject to annual national maximum rates published by the Ministry of Finance. A municipality applies one of these fees, not both. As part of Tax Automation & Intelligence, Mews automatically maintains supported municipal tax rates and applies the appropriate configuration to each property.
- Set up in minutes: In Mews Operations, go to the main menu > Settings > Property > Finance > Tax Configuration, open the Tax automation tab, and enter your address, latitude and longitude, and property details. The star rating and category, such as 4 stars Superior, matter most, because they can change which taxes apply.
- Configuration generated for you: Mews works with a specialist tax data provider to find the taxes that apply to your property.
- Always up to date: when a tax authority publishes a change, your rates update automatically. You do not need to check anything manually.

E-invoicing through KSeF
Poland's national e-invoicing system, KSeF or Krajowy System e-Faktur, is now mandatory for invoices to businesses and public bodies. An invoice is only valid once KSeF has accepted it and given it a KSeF number. The KSeF fiscal registry integration has been available in Mews since 30 April 2026 and is part of the Compliance Suite, alongside Tax Automation and Tax Intelligence.
Note: If you already use KSeF e-invoicing in Mews, nothing changes for you. Your integration and its configuration stay exactly as they are, whether or not you also use Tax Automation and Tax Intelligence.
- Sent automatically: when you close a bill or issue an invoice to an eligible company, Mews sends it to KSeF.
- KSeF number and QR code: Mews adds the KSeF number and a verification QR code to the invoice.
- PDF copy included: you can attach a PDF version of the invoice.
- Status on screen: check whether each invoice was accepted in Mews Operations under the main menu > Finance > Fiscal record report.
Key dates:
| Date | Who must issue invoices in KSeF |
|---|---|
| 1 February 2026 | Large businesses with sales above PLN 200 million in 2024 |
| 1 April 2026 | All other businesses |
| 1 January 2027 | Micro businesses with low monthly invoiced sales |
What you need to do:
- If you already use KSeF in Mews: nothing. Your setup carries over as it is.
- If you do not use it yet: get a KSeF certificate from the Polish Ministry of Finance. Mews does not provide it. Set up the integration in the Marketplace with your company details and NIP, upload the certificate, private key, and password, and upload a proof of ownership document. Approval can take up to 72 hours. Make sure each business customer's NIP is on their company profile.

Disabling Tax Automation
You can disable Tax Automation at any time. Disabling it does not stop your Compliance Suite subscription, and the other integrations in your Compliance Suite stay unchanged.
- Your configuration is deleted. Your accommodation tax rates are no longer updated automatically, so you need to check and update them yourself in Mews Operations under the main menu > Settings > Property > Finance > Tax Configuration. Tax Intelligence stays available in Finance as long as the Compliance Suite is active.
- To enable it again, open the same Tax automation tab and set it up again as you did the first time.
To stop paying, delete the Compliance Suite from the Marketplace. To learn how the Compliance Suite works and what to check before you make a change, see Managing the Mews Compliance Suite.
