Losing CIS Gross Payment Status: How to Appeal a Withdrawal

Gross Payment Status (GPS) is the single most valuable position a subcontractor can hold under the Construction Industry Scheme. With GPS, contractors pay you in full with no deduction at source, so you keep the 20% (registered) or 30% (unregistered) that would otherwise be withheld and reclaimed months later. Losing it is one of the central risks covered in the pillar guide, [Advanced CIS Compliance and HMRC Dispute Resolution](/guide/advanced-cis-compliance-hmrc-disputes/). This article sets out how HMRC reviews GPS, what triggers withdrawal, and how to defend it.

GPS rarely sits alone as a compliance issue. It interacts closely with the questions in the companion pieces on [deemed contractors and when non-construction businesses are pulled into CIS](/blog/deemed-contractors-cis-rules/) and on [CIS treatment of mixed supply-and-fit contracts](/blog/cis-mixed-contracts-supply-fit/), because the returns and payments those rules generate all feed the same compliance record HMRC tests at the annual review.

What Gross Payment Status is and why it matters

Under CIS, a contractor making a payment to a subcontractor for construction operations must deduct tax at source unless the subcontractor holds GPS. The three positions are: gross (0% deduction), registered net (20% deduction), and unregistered (30% deduction). The deduction is an advance against the subcontractor's eventual tax liability, but it is withheld immediately and only recovered later through the subcontractor's own returns.

For a substantial subcontractor turning over several million pounds a year, the difference between gross and net payment is the difference between holding working capital and lending it interest-free to HMRC for months. That is why GPS is treated as a strategic asset, and why its withdrawal can be commercially serious enough to threaten the viability of a business that bids on thin margins.

The three qualifying tests for Gross Payment Status

To obtain and keep GPS, a subcontractor must satisfy three tests set out in the CIS legislation. HMRC applies all three.

The business test

The applicant must be carrying on a business in the UK that consists of or includes construction operations, or supplying labour for construction operations, and that business must be run largely through a bank account. This test is about substance: HMRC wants to see a genuine construction business with a UK presence and proper banking arrangements, not a shell created to extract gross payments.

The turnover test

The business must show net construction turnover (excluding VAT and the cost of materials) above a minimum threshold in the 12 months before the application. The threshold differs by structure: there is a per-partner or per-director figure for partnerships and companies, and an alternative test based on total company turnover for larger companies. The figures are set in legislation and are periodically revised, so the current thresholds should always be confirmed against HMRC guidance before relying on them.

The compliance test

This is the test that causes most withdrawals. The applicant must have complied with all its tax obligations in the qualifying period, meaning it must have filed returns on time and paid amounts due on time across the relevant tax heads. This is the test reviewed every year, and the one a defence strategy has to be built around.

How the compliance test works in practice

The compliance test looks back over a 12-month review period and asks whether the business met every relevant filing and payment obligation. The categories typically tested include the following.

HMRC allows a limited tolerance for minor and infrequent failures. A small number of payments a few days late, or a return filed shortly after the deadline, will not automatically fail the test if the failures are minor in nature and the business otherwise has a clean record. The tolerance is not generous and it is applied at HMRC's discretion, so it is unwise to rely on it as a planning tool.

The annual review and how withdrawal happens

HMRC reviews every GPS holder's compliance roughly once a year. The review is largely automated: the system flags businesses with late filings or payments in the review period, and flagged cases are examined. Where the compliance test is failed and no tolerance or reasonable excuse applies, HMRC issues a notice of withdrawal.

The notice states the reason for withdrawal and the date from which it takes effect. From the effective date, every contractor paying the subcontractor must apply deductions again, at 20% if the subcontractor remains registered for net payment, or 30% if verification shows the subcontractor is not registered. The cash-flow impact begins immediately on the next payment cycle.

Your appeal rights and the 30-day window

A withdrawal notice carries a right of appeal. The appeal must normally be made in writing within 30 days of the date of the notice. Missing this window forfeits the right to challenge the decision through the normal route, so diarising the deadline the moment a notice arrives is critical.

The appeal sets out why the withdrawal is wrong: that the failures did not in fact occur, that they fall within HMRC's tolerance, or that there is a reasonable excuse. The steps usually run as follows.

1. 1Lodge the appeal in writing within 30 days, stating the grounds clearly.
2. 2Request that the withdrawal be suspended pending the appeal where the cash-flow impact would be severe.
3. 3Gather evidence: filing receipts, payment confirmations, bank statements, and any reasonable excuse documentation.
4. 4Respond to HMRC's review and, if the review upholds withdrawal, consider appealing to the First-tier Tribunal.
5. 5If GPS is ultimately lost, begin rebuilding a clean compliance record straight away so reapplication is possible after 12 months.

Defending GPS before a notice ever arrives

The strongest defence of GPS is never to fail the test. Because the test is mechanical and unforgiving, the controls that protect GPS are operational, not legal. The aim is a system where no relevant deadline is ever missed.

• Maintain a single compliance calendar covering every CIS300, PAYE, VAT, Corporation Tax, and Self Assessment deadline.
• Pay by direct debit or scheduled payment wherever HMRC allows it, and check that direct debits have actually cleared.
• Reconcile CIS deductions monthly so the figure paid over matches the returns filed.
• File CIS300 returns even in months with no payments, using the nil return where required.
• Run a quarterly internal review against HMRC's online account to catch any logged late filing or payment before the annual review does.

What to do in the GPS-withdrawn period

If GPS is withdrawn and not restored on appeal, the business operates under deduction until it can reapply. Reapplication generally requires 12 months of clean compliance from the withdrawal. During this period, the priority is to protect cash flow and rebuild the record. Reclaiming the deductions promptly through the company's Employer Payment Summary, or through Self Assessment for sole traders, recovers the withheld tax, although the timing lag is exactly the working-capital cost GPS was protecting against.

The cash-flow cost of losing GPS

Quantifying the impact helps a business judge how hard to fight a withdrawal and how much to invest in compliance controls. The cost is the working capital tied up between the moment a deduction is taken and the moment it is reclaimed. For a subcontractor with several million pounds of annual labour-based turnover, 20% withheld across the year is a large rolling balance, and the lag before recovery through company or personal returns can run to many months.

There is a second cost that is harder to measure but often larger: competitiveness. A subcontractor under deduction has tighter cash flow than a gross-paid rival bidding the same work, which constrains the contracts it can take on and the terms it can offer. On thin construction margins, that disadvantage compounds. The combined effect is why GPS is treated as a position to be defended actively rather than taken for granted.

Building a defence file before the review

A defence is far stronger when the evidence already exists rather than being assembled in a hurry after a notice arrives. A standing defence file means any reasonable excuse argument or tolerance claim can be made immediately and credibly. The file should capture, for the review period, the proof that obligations were met and the evidence behind any failure that did occur.

• Filing receipts and submission references for every CIS300, RTI submission, VAT return, and tax return.
• Bank statements and direct debit confirmations showing payments cleared on or before the due dates.
• A log of any failure, its cause, the date it was remedied, and the supporting evidence for any reasonable excuse.
• Correspondence with HMRC, including any agreed time-to-pay arrangements that protect the compliance record.
• A note of any HMRC information relied on, in case a failure flowed from incorrect guidance.

Common questions

Can HMRC withdraw GPS without warning?

HMRC issues a written notice setting out the reason and the effective date; it does not act silently. However, the notice can follow quickly after the review identifies a failure, so the first you may hear of a problem is the notice itself. This is why proactive monitoring of your own compliance record matters.

Does one late CIS300 return always lose GPS?

Not necessarily. A single minor and isolated late return may fall within HMRC's tolerance for minor failures, particularly where the rest of the record is clean. But there is no guarantee, and the safest assumption is that every late filing puts GPS at risk.

How long after withdrawal can we reapply?

Reapplication generally requires a clean compliance record for the 12 months following withdrawal. The business reapplies and is reassessed against the business, turnover, and compliance tests. There is no automatic reinstatement.

Should we appeal even if the failure clearly happened?

Where a genuine reasonable excuse exists, or where the failures are arguably minor and within tolerance, an appeal can still succeed. Where the record shows repeated and unexplained failures, an appeal is unlikely to succeed and effort is better spent rebuilding compliance for reapplication. Take advice on the specific facts.
