Trades and CIS
Verification, monthly CIS returns, the VAT domestic reverse charge, and reclaiming over-deducted CIS at year end. Get it wrong and you are lending HMRC money for free.
A quarter of working Harrow residents are self-employed, well above the London average. Sole traders, builders and trades on CIS, one-person companies and landlords. That is who this page is for.
In the 2021 Census, 25% of Harrow's working residents were self-employed, against about 20% across London, and most of them have no staff at all. Construction is a far bigger share of the local workforce than in London as a whole, and nearly nine in ten businesses in the borough employ four people or fewer.
So the accountancy problems here are rarely big-company problems. They are “am I on the right CIS rate”, “do I need to register for VAT yet” and “what does Making Tax Digital actually mean for me”. Practical questions. They deserve practical answers, not a sales pitch.
Harrow Council has extended selective licensing through 2026, covering Edgware and Roxeth from May, Greenhill and Marlborough from July, and Wealdstone North and South from September. Private renting has also grown fast, from 22% of households in 2011 to almost 30% by 2021.
Meanwhile Making Tax Digital for Income Tax is rolling out: over £50,000 of income now, £30,000 from April 2027 and £20,000 from April 2028.

Verification, monthly CIS returns, the VAT domestic reverse charge, and reclaiming over-deducted CIS at year end. Get it wrong and you are lending HMRC money for free.

Not legally, but CIS is easy to get wrong. As a subcontractor, you are often over-deducted and need to reclaim it. As a contractor, you have monthly returns and verification duties, with penalties for filing late. We handle both sides.
Licensing is a council requirement rather than a tax, but the licence fee and any works it triggers affect your property accounts. We make sure what is deductible gets deducted and what counts as capital is treated correctly.
Once your taxable turnover goes over £90,000 in any rolling 12-month period, or you expect it to within the next 30 days. We keep an eye on it so you don't register late.
Sometimes, if your affairs are very simple. Once you have rental income, CIS deductions or a limited company, one missed allowance or a late-filing penalty usually costs more than the fee. Ours is fixed and agreed up front, so you can judge it properly.
