# Construction & CIS

**Construction & CIS** support for trades in Cardiff and South Wales. Keep deductions, returns and records in order, improve cash flow, and stay on top of HMRC deadlines with clear, practical advice.

Working in construction means frequent payments, deductions and paperwork. This category brings your CIS position together with your wider accounts, so the numbers match and you know where you stand. We check your records, keep filings accurate and on time, and help you claim back overpaid deductions where due. You get plain-English updates, fewer surprises at year end, and more time to focus on jobs, not HMRC forms.

## Frequently Asked Questions

Do I need Construction & CIS support if I am a contractor or a subcontractor?

If CIS applies to the work you do, it is worth getting support whether you pay others, get paid yourself, or both. The goal is the same: keep deductions and reporting correct, avoid penalties, and make sure you are not leaving money unclaimed.

What will you need from me to manage CIS properly?

Usually we will ask for your CIS statements, invoices, details of payments made and received, and access to your bank records or accounting software. If you are unsure what you have, we will talk you through it and agree a simple routine going forward.

How do you help me stay on top of HMRC deadlines?

We agree a clear schedule and keep an eye on what is due, so nothing gets missed. We also review the figures before submission and let you know early if something looks off, so you can fix it without last-minute stress.

Can you help if my CIS records are behind or inconsistent?

Yes. We can review what you have, identify gaps, and work with you to get things back in order. Where HMRC needs to be updated, we will explain the options and the likely next steps in plain English.

How does CIS fit with my wider accounts and tax position?

CIS is part of the bigger picture, it affects cash flow, profits and what tax you may owe. We make sure the deductions and payments are reflected properly in your records, so your year-end accounts and tax calculations are based on accurate numbers.
