Sipson 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 Sipson?
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 Sipson or anywhere else in West London.
I searched "cis near me" — is this service really local to Sipson?
Sipson 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 Sipson 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.
Tax, briefly — the parts that affect Sipson
Selling a rental property triggers capital gains tax with a tight reporting window — UK residential sales must be reported and the tax paid within 60 days of completion. It's one of the easiest deadlines in the whole system to miss, and one of the most penalised.
First-year traders around Sipson tend to make the same three mistakes: registering late, mixing business and personal spending in one account, and saving nothing for the first tax bill. All three are avoidable in an afternoon of setup.
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.
Auto-enrolment applies from the first eligible employee: assess, enrol, contribute, declare. The Pensions Regulator does check, and the fines for ignoring it are out of proportion to how simple compliance actually is.
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 tax-free dividend allowance is down to £500, so almost any director taking dividends now pays some dividend tax — and needs a Self Assessment return to report it. The classic small-salary-plus-dividends strategy still works; it just needs actual planning rather than folklore.
UK residential property sales have their own regime: report and pay within 60 days of completion, separately from Self Assessment. Other gains report annually. Mixing up the two timetables is a common and expensive mistake.
Self Assessment lateness is priced in stages: £100 immediately, daily £10 penalties after three months (up to £900), then percentage-based charges at six and twelve months — all separate from interest on unpaid tax. The curve is designed to reward filing sooner, whatever the state of your records.
