How we support contractors in Cardiff and South Wales
Contractors face a unique set of accounting challenges. You need to stay on top of monthly returns, claim every legitimate expense, and navigate rules like IR35 or CIS depending on your sector. We work with IT contractors, construction professionals and freelancers across South Wales, handling everything from bookkeeping and payroll to tax planning and Companies House filings so you can concentrate on winning and delivering projects.
Our approach is straightforward. You get a dedicated accountant who understands contractor tax inside out, fixed monthly fees with no surprises, and access to cloud accounting software that keeps your records up to date in real time. We handle quarterly VAT returns, self-assessment, corporation tax and statutory accounts, plus proactive advice on how to structure your income tax-efficiently.
We make sure you claim every expense you're entitled to and never pay more tax than the law requires.
More information
Many contractors we meet have been stung by generic high-street accountants who don't understand the nuances of contract work. IR35 changes, off-payroll working rules, and CIS compliance all require specialist knowledge. We stay current with HMRC guidance and apply it to your specific situation, whether you're working inside or outside IR35, operating through your own limited company, or considering incorporation for the first time.
For construction contractors, we handle CIS monthly returns, verify subcontractor deductions, and help you apply for gross payment status when you're eligible. For IT and professional services contractors, we review your contracts, advise on working practices, and structure your salary and dividends to minimise your tax bill legally. We also support you with expense tracking, project cost analysis, and cashflow forecasting so you know exactly where you stand financially.
