MOSS
The EU Mini One-Stop-Shop scheme for cross-border B2C digital services, replaced by the wider OSS regime on 1 July 2021.
What it is
MOSS (Mini One-Stop-Shop) was the EU scheme introduced on 1 January 2015 that let suppliers of telecommunications, broadcasting and electronically supplied services declare VAT on B2C sales to EU consumers through a single return. It was superseded by the broader OSS on 1 July 2021, which extended the same idea to distance sales of goods and other services.
Where you meet it
You still meet MOSS in legacy data: historical VAT returns, older invoicing templates, and accounting exports covering periods up to Q2 2021. Tax-rules engines that support historical recalculation will keep a "scheme": "moss" branch for dates before 1 July 2021. Current registrations and filings use OSS.
What MOSS solved
Before MOSS, a digital-services supplier selling B2C across the EU was technically required to register for VAT in every member state where it had consumers. The compliance overhead made cross-border B2C digital services impractical for small and mid-sized sellers. MOSS replaced that with a single registration in the supplier's member state of identification, with a quarterly return covering all EU consumer sales of in-scope services.
The 2015 MOSS launch coincided with the change in place-of-supply rules for B2C digital services, which moved from the supplier's location to the consumer's location. MOSS was the simplification that made the new place-of-supply rules workable without forcing every digital seller into 28 separate VAT registrations.
What replaced it
The 2021 OSS reform extended the MOSS principle in three ways: it covered distance sales of goods (not just digital services), it included most other cross-border B2C services, and it added the parallel IOSS scheme for low-value imports. See OSS and IOSS for the current schemes.
Common confusions
- MOSS covered only digital services (TBE services). OSS extended the scheme to physical goods and most other cross-border B2C services.
- MOSS is not gone from the law books overnight. Corrections to old MOSS returns are still filed through the member state of identification where the original registration lived.
- "Non-Union MOSS" was the variant for non-EU-established digital-services suppliers; that variant rolled into "Non-Union OSS" with the 2021 reform.
