Looking for advice on landlord becoming tax compliant

[T McGibney]

What are the options if any available to a landlord who may have a tax liability that they cannot pay in full at once?

One for professional advice maybe? If you have tax arrears, and don't have sufficient funds available to bring your tax record up to date in one fell swoop, you are exponentially increasing the chances that Revenue will take a dim view of your non-compliance to date.
