- Tax law obligations, such as issuing structured invoices via KSeF, do not change the content of civil contracts or agreements.
- Structured invoices required by VAT law are public law documents and do not have civil law effects unless explicitly agreed upon in the contract.
- Tax law rights and obligations are separate from civil law relationships and do not affect the terms of contracts.
- The issuance of a tax invoice is secondary to the contract and does not alter its terms.
- In Poland, tax invoices are often used as commercial documents, but this is a result of business practice, not a legal requirement.
