About Our CIS Returns Service

The Construction Industry Scheme (CIS) requires contractors to deduct money from subcontractor payments and pass it to HMRC. Getting CIS wrong can result in significant penalties and cash flow problems. Our CIS specialists handle registration, monthly returns, deduction calculations, and reclaims, ensuring both contractors and subcontractors remain fully compliant. We also help subcontractors apply for gross payment status, which can significantly improve cash flow.

Frequently Asked Questions

CIS is a tax deduction scheme that applies to payments made by contractors to subcontractors in the construction industry. Contractors must deduct 20% (or 30% for unregistered subcontractors) from payments and pass the deductions to HMRC. These deductions count as advance tax payments for the subcontractor.

To qualify for gross payment status (receiving payments without deductions), you need to meet HMRC's turnover test (minimum £30,000 per year for sole traders), compliance test (filing and payment history), and business test (operating in the UK construction industry). We can assess your eligibility and handle the application.

HMRC charges penalties for late CIS returns: £100 for each month late for the first 6 months, then increasing to £500 or 5% of deductions, whichever is greater. We ensure your returns are always filed on time to avoid these penalties.
