What most people come to us for

CIS tax refunds

If you are registered for CIS, contractors take 20% from your pay before it reaches you (30% if you are not registered). It should only come off your labour, not the VAT or the materials you bought yourself. All of it counts towards your tax for the year, so if more was taken than you owe, the difference comes back to you.

Areas we cover

Trades and small businesses across North West London, from Harrow and Wembley to Ealing, Southall and Watford.
