Did you know that you can view also view our 2024 update? Take a look at 2024's e-invoicing changes here.

Throughout 2023 many countries are implementing and amending their electronic invoicing regulations. From Australia to Denmark to Panama. Take a look at the key changes below and download our free “Navigating global tax and e-invoicing compliance” guide for even more details.

Expected European changes


Currently, Denmark has mandatory business-to-government (B2G) electronic invoicing.

As part of a move towards further mandatory electronic invoicing (e-invoicing), the Danish Parliament passed a new Accounting Act on the 19th of May 2022. The act detailed new requirements concerning digital bookkeeping and digital bookkeeping systems, including Continuous Transaction Controls (CTCs) and the requirement to store records for at least 5 years. Businesses will also be required to meet new IT security standards and be able to automatically receive and transmit e-invoices.

The technical requirements are expected to be mandatory from the middle of 2023.


In May 2022, Luxembourg’s tax authority began its mandatory B2G e-invoicing journey. Like many countries, the mandatory regulations were introduced in stages depending on the size of business. Large businesses were first in scope, from October 2022 medium businesses were included and from March 2023 small and newly created businesses will be required to comply.

This year’s requirements will therefore cover 100% mandatory B2G e-invoicing across all of Luxembourg's businesses.


Just like Luxembourg, Portugal also implemented a phased approach to its mandatory B2G requirements. Portugal’s mandates began back in 2021 with large businesses. From July 2021 medium businesses were also required to comply, and from January 2023 small businesses were within scope.

Portuguese small businesses may have already been well prepared. January 2022 was the original date for small businesses to comply, and then July 2022. The latter date was postponed just one day before the mandates were due to come into effect. Finally, small businesses must now comply, therefore covering 100% mandatory B2G e-invoicing.


Since the 1st of January 2023, Serbian businesses must only send and receive business-to-business (B2B) electronic invoices. Serbia is one of the few European countries to mandate B2B e-invoicing. Numerous countries have B2B mandates on their roadmap (most recently Spain), but many are yet to confirm an exact date. We will be keeping track of the business uptake and reaction with our Unifiedpost Serbian team.


Throughout 2023, Slovakia will launch their electronic invoicing platform, IS EFA, for test purposes. The country’s Ministry of Finance will first test the platform with a small number of governmental units. The launch of the test phase has been postponed throughout 2022, but 2023’s test plan is likely to go ahead.

The country has not yet indicated when the platform will be used as part of mandatory processes. We are keeping track of any updates.

Expected changes further afield


In 2023, large Australian businesses have the right to only accept electronic invoices. The Australian tax authority is proactively promoting the use of e-invoicing, as a way to help businesses improve their efficiency. The country has adopted Peppol as their e-invoicing platform of choice, of which Unifiedpost Group is an accredited access point.


From the 1st of October 2023 a new system concerning the JCT (Japanese Consumption Tax) regime comes into force: Qualified Invoice System. JCT registered businesses will be required to add additional information on their invoices. The key difference compared to an invoice issued currently, is that a qualified invoice must include a breakdown of applicable tax rates for that given transaction.


Mexico has well-established B2G and B2B e-invoicing mandates already in place, but this doesn’t mean the country still won’t be making changes to improve their processes. In 2023, a new version of the country’s platform (CFDI 4.0) will come into force.


Panama, who currently has voluntarily e-invoicing, will be trialling a new mandate for selected pilot companies throughout 2023.

The Philippines

The Philippines has mandated electronic invoicing for large taxpayers. All invoices must be delivered to the tax authority within 72 hours of issuance.

Saudi Arabia

Saudi Arabia’s mandatory electronic invoicing journey began in 2022. Throughout 2023, certain businesses must integrate their e-invoicing system with the tax authority’s new platform - FATOORA. Find out which businesses will be within scope in our Saudi Arabia update.
