Timeline Update

B2B

Bill 8815 deposited in parliament with statutory B2B e-invoicing dates

The Minister of Finance deposited bill 8815 in the Chamber of Deputies on 30 July 2026 and referred it to the Council of State the same day. The deposited text fixes the dates the government communiqué of 17 July had left open: the law would enter into force on 1 January 2028, when recipients in scope must receive and process compliant electronic invoices, and the obligation to issue would apply from 1 July 2028 to issuers that exceeded at least two of three thresholds at the 2026 balance sheet date (balance sheet total of 7,500,000 euros, net turnover of 15,000,000 euros, 50 full-time staff on average) and from 1 January 2029 to all other issuers. Recipients may use transitional alternative technical solutions for reception until 30 June 2028, or until 31 December 2028 if they sit below those thresholds. The statutory text names no delivery network, leaving a grand-ducal regulation to designate one against nine criteria. Parliament has not yet voted the bill.

B2B

Government council approves draft bill extending e-invoicing to domestic B2B

The government council approved a draft bill amending the law of 16 May 2019 on electronic invoicing and the amended VAT law of 12 February 1979 , extending the obligation that currently applies to public procurement and concession contracts to domestic commercial transactions between businesses established in Luxembourg. The bill transposes Article 1 of Council Directive (EU) 2025/516 of 11 March 2025, which amends Directive 2006/112/EC as regards VAT rules for the digital age. A draft grand-ducal regulation fixing the common delivery network and the alternative technical solutions for issuing, transmitting and receiving e-invoices was endorsed alongside it, so that issuers and recipients are not forced onto separate, non-interoperable systems. The bill has yet to pass through parliament and no implementation dates have been set.
