CIS Gross Payment Status: How to Apply and the Benefits 2026

The Construction Industry Scheme (CIS) affects hundreds of thousands of subcontractors working across the UK's building, civil engineering, and infrastructure sectors. Under the standard rules, contractors deduct tax at source before paying subcontractors. But with gross payment status, you can receive your full payment without deduction and settle tax yourself through Self Assessment. Here is what that involves in 2026/27.

How CIS Deductions Work by Default

When a contractor pays a subcontractor under CIS, they are required to verify the subcontractor's status with HMRC first. Based on that verification, the deduction rate applied is:

• 20% for registered subcontractors
• 30% for unregistered subcontractors
• 0% for those holding gross payment status

The 20% or 30% is deducted from the labour element of the payment (not materials) and paid directly to HMRC by the contractor. It is treated as an advance payment of the subcontractor's income tax and NI liability.

For a subcontractor earning GBP 80,000 in labour income under standard CIS, the contractor retains GBP 16,000 before the subcontractor sees a penny. That money sits with HMRC until the subcontractor files their Self Assessment return and the credit is offset against the final tax bill or refunded.

What Is Gross Payment Status?

Gross payment status (GPS) means HMRC authorises a subcontractor to receive gross payments -- the full amount without any CIS deduction. The subcontractor then declares all CIS income on their Self Assessment return and pays the tax and National Insurance due in the normal way: by 31 January following the end of the tax year, with a payment on account due the following 31 July.

This matters for cash flow. If your business relies on that 20% to fund materials, equipment, or wages for your own workers, waiting months for a CIS credit refund can create real pressure. GPS eliminates the problem entirely.

Who Can Apply?

HMRC assesses GPS applications against three tests:

1. Business test: The applicant must be a genuine business -- a sole trader, partnership, or company -- genuinely carrying out construction work. It cannot be a shell or newly formed entity with no trading history.

2. Turnover test: Net CIS turnover (excluding materials and VAT) must meet minimum thresholds over the 12 months before the application. For sole traders and partnerships, the threshold is GBP 30,000 per partner. For companies, it is GBP 30,000 per director (up to a maximum of GBP 100,000, regardless of company size).

3. Compliance test: This is the most demanding. HMRC reviews whether the applicant has:

• Filed all tax returns on time
• Paid all tax and NI on time (or within 28 days of the due date in limited circumstances)
• Operated PAYE correctly if they have employees
• Complied with VAT obligations if registered

A single serious compliance failure -- such as a late return or underpayment -- can result in GPS being refused or revoked. HMRC applies this test strictly.

How to Apply

Applications are made through the Government Gateway. You will need your Unique Taxpayer Reference (UTR), your business's CIS registration details, and records to support the turnover figures. HMRC typically processes applications within 30 days, though it can take longer if further information is required.

If your application is refused, HMRC will give reasons. You can appeal against a refusal if you believe HMRC has applied the test incorrectly.

Maintaining GPS

Gross payment status is not permanent. HMRC reviews compliance annually and can revoke GPS if you fall behind on returns or payments. If GPS is cancelled, you revert to the standard 20% deduction rate immediately. Reinstatement after cancellation requires going through the full application process again and demonstrating a clean compliance record.

This means GPS holders need to be especially diligent about:

• Filing Self Assessment returns on time (by 31 January)
• Paying tax on account by 31 July and the balancing payment by 31 January
• Filing VAT returns and making VAT payments punctually if VAT-registered (the VAT registration threshold is GBP 90,000)
• Running payroll correctly if employing workers, including RTI submissions

Corporation Tax Considerations

If your CIS business operates through a limited company, Corporation Tax rates apply rather than personal income tax. Profits up to GBP 50,000 attract a 19% Corporation Tax rate. Profits above GBP 250,000 are taxed at 25%. Marginal relief applies on profits between those thresholds.

GPS for companies is assessed at company level, not director level for tax purposes, though the turnover test uses per-director thresholds. Company directors also pay themselves a salary subject to PAYE, which interacts with NI. The Employer NI rate from April 2026 is 15% above the secondary threshold of GBP 5,000.

Is GPS Worth It?

For most established subcontractors with good compliance records and sufficient turnover, GPS is almost always worth pursuing. The cash flow benefit is immediate and the administrative overhead is no greater than filing Self Assessment anyway. The risk is the compliance requirement -- if you are not already meticulous about deadlines, GPS adds real exposure.
