Construction Industry Scheme support for Greater Manchester contractors and subcontractors — monthly returns, verifications, deduction statements and refunds.

Quick answer
Contractors must file a CIS300 monthly return by the 19th of each month. Deductions are 20% for registered subcontractors and 30% for unregistered ones; those with gross payment status have none.
We claim them through your tax return or company payroll.
Penalties start at £100 per late return and increase over time.
We check the business, turnover and compliance tests.

We confirm a fixed price after reviewing your records. What changes the price:
| Factor | Why it matters |
|---|---|
| Number of subcontractors | More verifications and statements |
| Monthly activity | Volume of invoices |
| Refund history | Back years take extra work |
We check whether HMRC needs a nil return or an inactivity notice for your scheme that month, and handle it for you.
It depends on HMRC processing; filing early helps.
Yes, if compliance slips — and reapplying can be barred for a period.
