Harmondsworth 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 Harmondsworth?
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 Harmondsworth or anywhere else in West London.
I searched "cis near me" — is this service really local to Harmondsworth?
Harmondsworth 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 Harmondsworth 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
The best time to switch is after a filing, but it works at any point in the year. What matters is not letting a looming deadline stop you: a new firm can usually pick up an in-flight year faster than you'd think.
Filing early doesn't mean paying early: submit a return in May and the tax is still not due until the usual dates. Early filing buys certainty, refund speed and time to arrange payment — it costs nothing.
The July payment on account is the forgotten deadline: no return is due, but money often is. We diary it for every client it applies to, because HMRC charges interest from the day it's late even though nothing was "filed" late.
Plenty of people incorporate too early because it "sounds established", then pay for accounts, confirmation statements and payroll they didn't need. The switch pays for itself at the right profit level — the trick is knowing yours.
CIS deduction statements go missing constantly — contractors change, emails vanish. HMRC's records can fill some gaps, but the fastest refunds belong to subcontractors who keep every monthly statement. If you're in construction around Harmondsworth, that one habit is worth real money.
Can't pay the bill by the deadline? File anyway. Filing and payment are penalised separately, and HMRC's Time to Pay arrangements can spread the bill — but only once the return is in. Not filing because you can't pay turns one problem into two.
Ask any prospective accountant two questions: "what's included in the fee?" and "what costs extra?" The quality of those two answers predicts the whole relationship.
The first hire brings PAYE registration, Real Time Information submissions every payday, workplace pension auto-enrolment and payslips that must be right. It's all completely manageable — as a monthly routine run by software, not a monthly crisis.
General guidance, not personal advice — thresholds and dates change. For advice on your own position in Harmondsworth, message us and we'll answer against your actual numbers.
