hi there
cis is changing this year, there will no l0nger be any cards, and the IR will inform contractors of the subbies status , ie gross or net payments.
if yu are a limited company your cis deductions can be offset against your monthly paye return, if you are a sole trader or partnership you cannot do that.
and in that case your cis deductions are offset at the end of year against any tax due to be paid in your tax return.
there is a technicality in build cleaning, in the fact that if you clean new houses that are finished ie build complete, and are purely stock, or showhomes, then these are not liable to CIS.
if you are VAT registered, VAT is not charged on the construction related cleans, but stock plots, showhomes and site cmpounds are VATable.
regards
martin
