HMRC's Non-Statutory Clearance Service Now Has A 30-Day Clock
HMRC's non-statutory clearance service is how a business gets an advance, written view from HMRC on an uncertain tax position before it signs off a sale, a restructuring or an unusual VAT treatment. From 31 July 2026, HMRC's guidance for the service adds a hard deadline to keeping that application alive: if HMRC asks for more information, the business must supply it within 30 days of the date on the letter, or, in HMRC's own words, “applications may be closed and not considered further.”
The clearance itself is non-statutory: informal, at HMRC's discretion, and not a legal ruling. HMRC's own guidance says VAT non-statutory clearance requests specifically are taking approximately 12 weeks, nearly three months, to process. A business now has 30 days to answer that follow-up request, inside a VAT process that alone can take three months to reply, with no allowance for a query landing while records are still being gathered, an adviser is on leave, or the letter is simply missed.
Miss the window and the application does not pause, it closes. The business starts again, the clock resets, and whatever the clearance was for, a sale completing, a restructuring signed off, does not wait with it. The one this really catches is not someone gaming the system. It is the owner or adviser juggling a live deal and a slow-moving HMRC letter that landed at the wrong time.
- Is a 30-day deadline on supplying extra information a reasonable tightening of an informal service, or a trap that lets HMRC close down inconvenient applications?
- With VAT non-statutory clearance requests already taking around 12 weeks on HMRC's own figures, is it fair to hold applicants to a far tighter clock than HMRC holds itself to?
- What should businesses and their advisers do differently now to avoid being timed out of a clearance they are relying on? Do you have a client whose plans this would change? If so, please give as much colour and detail as possible.
