Castle Baynard 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 Castle Baynard?
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 Castle Baynard or anywhere else in Central London.
I searched "cis near me" — is this service really local to Castle Baynard?
Castle Baynard 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 Castle Baynard town centre or the edge of Central 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
First-year traders around Castle Baynard 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.
Crypto traders rack up hundreds of taxable events without noticing, because every swap counts as a disposal. Specialist software plus the pooling rules turns the mess into a number; guessing does not.
HMRC receives data directly from online platforms about sellers' income. If a side hustle has grown past the £1,000 trading allowance, coming forward first is always cheaper than being written to — penalties scale with how the disclosure starts.
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.
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.
The capital gains annual exempt amount has shrunk to £3,000, which pulls far more ordinary disposals — shares, crypto, second properties — into reporting territory. Gains that once fell under the allowance now need a return, even when the tax due is modest.
A limited company juggles two regulators: Companies House wants accounts within nine months of year end, HMRC wants corporation tax paid at nine months and a day. Same starting point, different documents — and late filing penalties at Companies House escalate automatically and are rarely cancelled.
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.
General guidance, not personal advice — thresholds and dates change. For advice on your own position in Castle Baynard, message us and we'll answer against your actual numbers.
