What is the UK VAT gap and how is HMRC closing it?
Effective: ongoing · Authority: HM Revenue & Customs (HMRC)
The UK's VAT gap — the difference between VAT theoretically due and actually collected — recently stood at £8.9 billion, representing approximately 5% of theoretical liability. HMRC's digital strategy, including Making Tax Digital (MTD) and the forthcoming 2029 B2B e-invoicing mandate, is designed to close this gap by increasing transaction-level visibility and reducing misreporting.
How does HMRC's digital strategy close the VAT gap?
HMRC's multi-phase digital strategy progressively increases transaction-level visibility:
- MTD for VAT (live): Digital VAT returns via compatible software eliminate manual transfer errors
- 2029 B2B e-invoicing mandate: Structured invoice exchange creates a transaction-level audit trail
- Digital record keeping: MTD requires digital records for all VAT transactions, enabling more efficient audit
