HMRC receives data from letting agents, deposit schemes, the Land Registry and booking platforms, and writes to landlords it believes have undeclared income. Coming forward voluntarily earns significantly lower penalties than waiting to be found, and for many landlords the final bill is far smaller than the years of worry that preceded it.
It depends on why the income went undeclared. Careless behaviour can mean up to six years, deliberate concealment up to twenty. Getting the classification right drives both the years assessed and the penalty rate, and it is where a specialist earns the fee.
