HMRC has introduced a new requirement for UK VAT registration, effective 19 January 2026, that businesses must provide the unique VAT registration application reference number before adding VAT to a Business Tax Account. This step aims to close a fraud window where criminals linked VAT numbers to Government Gateway accounts before the legitimate owner could log in. Businesses should safeguard the reference number and act swiftly after registration to mitigate fraud risks.

Saudi Arabia’s Zakat, Tax and Customs Authority (ZATCA) has issued amendments to the VAT Implementing Regulations that clarify the responsibilities of electronic marketplaces and e-commerce platforms. The changes define when a marketplace is deemed to facilitate a supply and therefore liable for VAT, and introduce phased effective dates for compliance. Businesses operating in the Kingdom should review their operating models and contractual arrangements to ensure alignment with the updated framework.

Canada has increased the maximum GST credit from $700 to $900 to help low‑income families cope with high food inflation. A family of four could receive up to $1,890 this year and about $1,400 annually for the next four years. Eligibility is based on filing a tax return, and the change comes amid a 6.2% food inflation rate in December 2025.

Austria has lowered its reduced VAT rate from 10% to 5% for a defined basket of goods, effective 1 July 2026. The change applies only to specified goods and does not affect the standard rate.

The UK Supreme Court confirmed that VAT incurred on adviser fees related to an exempt share sale is not recoverable, applying a strict two‑stage test that requires a direct and immediate link to the transaction. The ruling rejects the modified approach that allowed recovery based on intended use of proceeds and clarifies that VAT grouping does not alter the nature of a share sale. Businesses must conduct early VAT analysis for share disposals to account for irrecoverable adviser fees.
