Isleworth 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 Isleworth?
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 Isleworth or anywhere else in West London.
I searched "cis near me" — is this service really local to Isleworth?
Isleworth 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 Isleworth town centre or the edge of 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
If you're a sole trader or landlord anywhere near the £50,000 income mark, Making Tax Digital will change your filing rhythm from 2026: four digital updates a year plus a final declaration. Clients who move their records to software early find the transition a non-event.
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 Isleworth clients who come to us in January still file on time; the records just need to arrive before the last week.
Company deadlines run off your accounting year end, not the tax year: corporation tax is payable nine months and one day after year end, and the CT600 return is due twelve months after. Confusingly, the payment is due before the return — a sequencing quirk that catches new directors.
Rental profits need reporting once they're more than trivial, and the rules differ for furnished holiday lets, rent-a-room and ordinary lets. Landlords are also in the first wave of Making Tax Digital — property income counts towards the £50,000 threshold.
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 honest answer changes with your profits. At lower profits, sole trader simplicity usually wins; as profits grow, a limited company's mix of salary and dividends, corporation tax rates and liability protection starts earning its extra admin. We run the actual numbers before recommending either.
Compliance checks are usually specific: one return, one figure, one question. Answered promptly and with evidence, most close quickly. The expensive enquiries are the ones that started as unanswered letters.
The trading allowance means up to £1,000 of gross side income per year can be tax-free with no return needed. Above that, registration and reporting kick in — and platforms now report seller data to HMRC, so "under the radar" isn't a strategy any more.
General guidance, not personal advice — thresholds and dates change. For advice on your own position in Isleworth, message us and we'll answer against your actual numbers.
