Your Company & KSeF: A Checklist to See if the Obligation Applies to You

The implementation of KSeF is a major topic in the business world. Undoubtedly, many entrepreneurs still ask the fundamental question: “Does this really apply to my company?”. Therefore, we have prepared a practical checklist to help you determine the relationship between your company and KSeF. Furthermore, remember that your accounting office can always help you interpret the regulations.

Step 1: Are You a Taxpayer Registered in Poland?

This is the first and most basic criterion. Namely, the obligation to issue invoices in KSeF applies to taxpayers who have a registered office or a fixed place of business in Poland.

  • YES, I have a registered office or a fixed place of business in Poland. In that case, proceed to Step 2. The KSeF obligation likely applies to you.
  • NO, I operate from abroad and do not have a fixed establishment in Poland. As a rule, the KSeF obligation does not apply to you, even if you are registered for VAT in Poland.

Step 2: Your Company and KSeF – VAT Payer Status

Many people think KSeF only applies to “VAT payers.” However, that’s a mistake! The obligation covers a much broader group.

  • YES, I am an active VAT payer. The KSeF obligation fully applies to your B2B transactions. Therefore, proceed to Step 3.
  • YES, I am a taxpayer exempt from VAT. The KSeF obligation also applies to you! If you issue invoices to other businesses, you will have to do it through the system. Your bookkeeping must be prepared for this.

Step 3: Who Do You Issue Invoices For?

This is the most important element that determines the exemptions from the obligation.

  • I issue invoices MAINLY for other businesses (B2B). This is the core of KSeF. As a result, all your invoices for other entrepreneurs will have to go through the system.
  • I issue invoices MAINLY for private individuals (B2C). Good news! Namely, the legislator excluded invoicing for consumers from mandatory KSeF.
  • I issue invoices for foreign contractors. An exemption also applies here. As a rule, you do not have to send invoices to KSeF for companies without a fixed place of business in Poland.
