TC09668 - [2025] UKFTT 01255 (TC)

A taxpayer is not liable to either penalty points or a financial penalty for late submission if they can establish that they had a reasonable excuse for their failure and put that failure right without unreasonable delay after the excuse has ended.

It is statutorily provided that neither an insufficiency of funds (unless attributable to events outside the taxpayer’s control), or reliance on another person to do anything (unless the person took reasonable care to avoid the failure) is a reasonable excuse.
