CIS Made Simple for Croydon Contractors & Subcontractors

Croydon is one of South London's major commercial and residential development hubs, with significant ongoing construction activity across CR0 and a large population of CIS contractors and subcontractors working on regeneration and residential projects. For Croydon tradespeople, managing CIS correctly means avoiding automatic penalties, maintaining good standing with HMRC and maximising the refund available at year end. Your Tax Help Accountants, HMRC-registered, handles CIS for Croydon contractors and subcontractors fully online — monthly returns, deduction statements, verification, refund claims and self-assessment — at a fixed monthly fee with same-day filing.

💡 As an HMRC-registered agent we deal with HMRC directly on your behalf — filing your CIS returns, verifying subcontractors, managing your compliance and claiming back any overpaid tax.

CIS Questions Answered

Frequently Asked CIS Questions

What is the difference between gross payment and net payment under CIS in Croydon?
A gross payment means you receive the full payment with no CIS deduction — this only applies to subcontractors with gross payment status approved by HMRC. A net payment means the contractor deducts CIS before paying you — either 20% for registered subcontractors or 30% for unregistered ones. The deducted amount is paid to HMRC and counts as tax you have already paid, which is reconciled through your self-assessment return.
How long does a CIS refund take to arrive once filed in Croydon?
Once we file your self-assessment return HMRC typically processes CIS refunds within 6 to 8 weeks, though it can be faster. We file your return as early as possible after the tax year ends — from the beginning of April — to minimise your wait. We also follow up with HMRC if the refund takes longer than expected.
I'm a Croydon property developer — does CIS apply to my renovation projects?
It depends on the nature of the work and who carries it out. If you are engaging self-employed tradespeople or construction firms to carry out construction work on your properties, CIS obligations may apply to you as a deemed contractor. We assess your specific situation and advise on whether and how CIS applies to your development activities.
Can you help a Croydon construction business get UTR numbers for new subcontractors?
We can advise subcontractors on how to register for self-assessment and obtain their UTR, and we handle the verification process once they have one. Getting subcontractors properly registered before work starts protects you from the higher 30% deduction rate and any HMRC enquiries about worker status.
