An accountant who actually understands CIS

Construction accounting isn't the same as other industries. CIS adds a layer of complexity that most general accountants aren't set up to deal with properly — and it costs subcontractors money when it's not handled right.

I specialise in CIS. I deal with subcontractors and contractors every day across Rochester, Medway and Kent, and I know exactly how to make the system work in your favour. That means correct deductions, on-time monthly returns, and getting every penny back that you're owed.

Most CIS subcontractors overpay tax. If 20% is being deducted from your gross payments but your actual tax bill is lower once expenses are factored in, the difference is your refund. I see clients getting back hundreds to thousands every year.

CIS services

CIS registration

Registered with HMRC as a subcontractor or contractor, on the right deduction rate from day one.

Monthly CIS returns

Filed on time, every month. Late returns mean £100 penalties — I make sure that never happens.

Subcontractor verification

Every subcontractor verified with HMRC before payment, so you deduct at the correct rate.

CIS tax refund claims

Overpaid through CIS deductions? I claim it back — often going back up to four years.

Year-end self assessment

Your CIS income, expenses and deductions all flow into a properly prepared tax return.
