South Harrow cis tax returns FAQs
How much CIS refund am I owed?
Most subcontractors have 20% deducted at source all year — usually more than their final tax bill once expenses and the personal allowance are counted. Refunds of £1,500–£3,000 are common, claimed through your Self Assessment.
How quickly will my refund arrive?
Once the return is filed, HMRC typically pays CIS refunds within 2–6 weeks. We file promptly after 6 April so the claim is in the queue as early as possible.
What is gross payment status?
It lets contractors pay you without CIS deductions — better cash flow. You need to pass HMRC's turnover and compliance tests; we assess whether you qualify and handle the application.
Do I need to visit an office in South Harrow?
No — there's nothing to visit and nothing to print. We're an online firm: records go through our secure portal or WhatsApp, and everything is filed electronically. It works the same whether you're in South Harrow or anywhere else in North West London.
I searched "cis near me" — is this service really local to South Harrow?
South Harrow is fully covered, yes. The work is done online, which in practice means more local than an office: same-day replies instead of appointment slots, and the same published fixed fee whether you're in South Harrow town centre or the edge of North West London. If you'd rather talk it through first, WhatsApp us — a real person answers.
Who will actually handle my cis?
Bohzo Accountants — a trading name of Bohzo Ltd, a registered UK company (No. 15031604). You get a named contact, a fixed fee in writing, and nothing is filed until you've reviewed and approved it.
How do your fixed fees work?
You tell us your situation, we quote one fixed price in writing before any work starts, and that price never changes mid-job. If your case is unusually complex we'll say so up front and agree a different fixed price — but the fee is always agreed before we begin, never after.
Things worth knowing before your next filing
Some businesses register for VAT before they must — reclaiming input VAT can be worth it if your customers are VAT-registered themselves. Others should stay below deliberately. It's a real decision with real numbers, not a formality.
The businesses that struggle with tax bills rarely have a tax problem; they have a timing problem. Knowing the bill in September instead of January — which filing early gives you for free — is the difference between planning and scrambling.
The expenses rule is "wholly and exclusively" for the trade — which covers more than most people claim (proportionate home-working costs, business mileage, software subscriptions) and less than some hope (client entertaining, everyday clothing). Knowing the line is where the savings live.
Limited companies in CIS reclaim differently to sole traders — through payroll or the company tax return rather than Self Assessment. Plenty of construction companies sit on refundable deductions without realising; a quick review of the CIS position often pays for itself immediately.
Online Self Assessment returns are due by 31 January, along with any balancing payment — and HMRC's £100 penalty applies the moment the deadline passes, even if you owe nothing. Most South Harrow clients who come to us in January still file on time; the records just need to arrive before the last week.
The first tax bill is the hardest because it can arrive with payments on account attached — up to 150% of the year's tax in one go. New businesses that save a quarter to a third of profits from day one never feel it.
HMRC requires records to be kept for at least five years after the filing deadline for the self-employed. Digital copies count. A cloud folder or app now beats a carrier bag of paper every time — for you and for any future enquiry.
If you contract through your own limited company, IR35 asks whether you'd be an employee without it. For medium and large clients, the status decision is theirs; for small clients, it's still yours — and getting it wrong in either direction costs money.
General guidance, not personal advice — thresholds and dates change. For advice on your own position in South Harrow, message us and we'll answer against your actual numbers.
