Something broadly based, including taxing things like corporate profits. I've never quite worked out what good the pretend corporates based here are doing us.

Regardless, basing your tax take on property building and transactions is not a good plan, was not a good plan.

The current plan is to cut spending and increase taxes and service charges, because a deflationary spiral will increase the tax take or something. <shrug> Fucked if I know how that's meant to work, but it makes the Commission, the ECB and the financial markets sort of happy.
