One thing I really wish the govt. would do is to introduce compulsory registration of all landlords, so that it’d be much harder to avoid paying tax on rental income. From all I’ve ever heard - including at least one very close source - this is rife.
We have one small rental property and there is absolutely nobody I am legally obliged to inform. On the self-assessment tax return, where I declare the income, I don’t even have to give the address - all it asks is how many properties you are renting out, and what the income is.
It’s far too easy to omit to declare at all, or to under-declare.
I’m sure someone will now start blaming the Tories, but Labour did nothing about it either, and Labour were in power when buy-to-let was positively mushrooming - at least partly, I might add, because after Gordon Brown’s raid on pension funds, property was seen as a safer bet.
