KSeF Implementation: What Employees Must Know About Documenting Purchases from 2026

• From February 1, 2026, all taxpayers must receive invoices via the National e-Invoice System (KSeF).
• Employees making purchases on behalf of employers need to understand new documentation rules, as various invoice types and confirmations will exist.
• Internal company regulations on documenting purchases will be helpful.
• Some large companies are issuing their own guidelines for purchase documentation, which may serve both as information campaigns and as a way to impose their processes on partners.
• These company-specific guidelines are sometimes vague and may not fully address key questions about transaction documentation.
