The short answer: two dates that actually matter for OSS users<\/h2>\n

Commission Implementing Regulation (EU) 2026\/1869<\/a> is already law. It entered into force on 17 August 2026, twenty days after publication in the Official Journal of the European Union. But if you sell through the OSS (the One Stop Shop, the EU’s single portal for declaring and paying VAT on cross-border B2C sales instead of registering in every country you sell to), the practical impact lands in two separate steps. Registration-data changes apply from 1 January 2027 through 30 June 2028. The new return format and a fourth special scheme only take effect from 1 July 2028. Until that second date, your current OSS reporting stays exactly as it is.<\/p>\n

What EU 2026\/1869 actually is, and isn’t<\/h2>\n

The regulation sits inside the wider ViDA package (VAT in the Digital Age)<\/a>, but it isn’t the same thing as ViDA. It fine-tunes the technical and reporting rules for the OSS and IOSS (the Import One Stop Shop, the equivalent scheme for goods imported from outside the EU and sold directly to consumers). This regulation does not introduce any new real-time e-invoicing obligation for OSS users; that’s a separate, later part of ViDA, and it isn’t what this rule is about.<\/p>\n

What changes from 1 January 2027?<\/h2>\n

From this date, listing a website in your OSS registration becomes mandatory only “where available.” So if you don’t run a website, you’re not forced to invent one for the form. VAT group details get more precise, and if you’re part of a VAT group, you can no longer enter fixed-establishment data in the field meant for VAT group information. The Commission’s implementing regulation<\/a> treats this as a technical correction to the registration form, not a new obligation on top of what you already do.<\/p>\n

What changes from 1 July 2028?<\/h2>\n

The current return is replaced by a single electronic message format covering four schemes at once: the non-Union scheme, the Union scheme, the import scheme, and a new own-goods transfer scheme for moving your own inventory between Member States. A nil return stays mandatory if you made no supplies in a period. Corrections will need a stated reason attached, such as a cancelled sale or a wrong VAT rate, and the data itself gets broken down further, by country, by country of dispatch, and by VAT rate.<\/p>\n

Who does this hit hardest?<\/h2>\n

This lands heaviest on sellers who hold stock in Germany, Poland or elsewhere in the EU, and on marketplaces that act as the deemed supplier, meaning the platform, not the underlying seller, is treated as making the sale and is responsible for the VAT. For both groups, getting the country of dispatch and the VAT number data exactly right becomes the whole game. Report the wrong country and you’ve just sent the wrong VAT to the wrong Member State.<\/p>\n

What stays the same?<\/h2>\n

The Union OSS scheme remains quarterly. Estonia’s Tax and Customs Board confirms that the deadline is the last day of the month following the quarter<\/a>. Nil returns still work the same way, corrections still run through a later return within three years<\/a>, and this regulation doesn’t introduce any new \u20ac10,000 distance-selling threshold or any OSS-specific EU-level penalty.<\/p>\n
