HMRC Self Assessment manual updated on GOV.UK
HMRC has updated its Self Assessment manual on GOV.UK. The manual contains internal guidance and processes that HMRC staff use when dealing with Self Assessment matters.
The update does not announce any new rules, deadlines, or thresholds, so sole traders, landlords, and small businesses do not need to take any specific action as a result of this change.
If you want to understand how HMRC approaches Self Assessment behind the scenes — for example when checking returns or handling queries — the manual is publicly available and can be a useful reference.
