CIS Accountants

All contractors operating in the UK, even if they’re based overseas, are required to register for the CIS and take deductions from subcontractors’ pay. These count as advance payments toward subcontractors’ tax and National Insurance contributions.

CIS accountants for contractors

Contractors are required to inform HMRC of the CIS tax deductions they make by filing a CIS tax return by the 19th of every month.

Accuracy on these returns is imperative, as mistakes can incur penalties of up to £3000. It’s also vital to file them on time; if you’re just one day late, you’ll be landed with a £100 fine.

Remind you when it’s time to file a return and request information every month

Add and verify new subcontractors

Process payslips and deduction statements for subcontractors

Submit your monthly CIS returns

Represent you in all tax-related correspondence and investigations
