From April 2026, the size thresholds that decide whether a client counts as small under the off-payroll working rules rose to £15 million turnover and £7.5 million balance sheet. Clients newly classed as small no longer determine your IR35 status. That responsibility shifts to your own limited company instead, and getting it wrong creates a personal tax exposure many contractors do not expect.
We handle the accounting side of contracting through a limited company, from corporation tax and dividend planning to your own Self Assessment, and flag where an IR35 review is worth getting before you sign a new contract.
Many contractors assume their client always determines IR35 status, since that has been true for medium and large businesses since 2021. When a client falls under the small company thresholds, that responsibility moves back to the contractor’s own company under the older rules, often without the contractor realising the change happened. This is exactly why status needs checking at the start of every new engagement, not assumed from the last one. We flag this at contract renewal so you are never caught assuming someone else made the determination.
This service is for anyone contracting through their own limited company in or around Slough. We work with contractors across the Thames Valley, including many IT and technology contractors supplying the large employers in Reading and Bracknell.
We manage your company accounts, tax filings, and payroll through your contracting company.
We structure your income to be tax efficient within current HMRC rules.
We flag where your client’s size classification affects who determines your IR35 status, so nothing is assumed.
Your personal Self Assessment return is filed alongside your company accounts, kept consistent with each other.
Medium and large clients determine it under the 2021 rules. Where a client falls under the small company thresholds, your own limited company determines it instead.
The size thresholds used to classify a client as small increased, to £15 million turnover and £7.5 million balance sheet, moving some clients out of the medium and large category.
It depends on your overall income and current tax rates. We review this each year rather than applying a fixed formula.
We can review the accounting and tax implications, including flagging where an IR35 determination is required.
