Specialist CIS tax
return accountants
in London

If you or your business are involved in the construction industry, you will no doubt be aware of the Construction Industry Scheme (CIS) and how it works. In simple terms, when a contractor pays a subcontractor, they must deduct money from this payment and pass it on to HMRC. As specialist CIS tax return accountants in London, our payroll expertise allows us to support you with any CIS needs you may have. If you are debating taking on subcontractors due to CIS implications or are concerned about penalties for not completing complex CIS tax returns, our team can take this stress off your shoulders by advising you on the best approach or submitting your returns for you.

Registering for CIS returns

Whether you are a contractor or subcontractor, we can provide you with support on every aspect of CIS returns to ensure you are following regulations correctly. We’ve helped a wide range of London clients and businesses who work in the construction industry, developing extensive knowledge in this area.

Register as a contractor
If your business employs subcontractors for construction work or you have spent £3 million on construction in the 12 months since you made your first payment, you must register for CIS. We are able to complete this process for you to ensure you are not at risk of any penalties.

Register as a subcontractor
As a subcontractor being paid for your work, it is not required for you to register for CIS, but it is recommended, as larger deductions are taken from payments to you if you are not. We can ensure subcontractors are registered so that they minimise their CIS deductions.

Submitting CIS returns for your business in London

As a contractor, you are required to file your CIS returns online on a monthly basis and to verify any subcontractors you employ. We can manage this process to submit your returns for you, taking care of the complicated forms and calculating your CIS deduction so you know exactly what you have to pay HMRC. Our years of expertise mean we can utilise our experience to submit your CIS returns for you, saving you as much time and money as possible.

Supporting you with CIS refunds

If you have been managing your CIS returns and believe you have been paying excessive amounts, we are here to help put your mind at ease. We have a process in place to deal with these situations:

  • We investigate your claim, keeping you informed of the process and calculating how much of a refund you may be entitled to.
  • Once we have clarified and agreed with you on how much we believe you are entitled to, we submit this claim and all the documentation to HMRC.
  • This claim is processed by HMRC, and if successful you keep however much you are awarded.

Arrange a free consultation to discuss your claim with us today and find out how much of a CIS refund you may be entitled to.
