Isleworth r&d tax credits FAQs
Does my work actually qualify as R&D?
The test is whether you sought an advance in science or technology by resolving uncertainty a competent professional couldn't readily solve. Routine development doesn't qualify; genuine technical problem-solving often does. Our free eligibility review gives you a straight answer before you spend anything.
How much is a claim worth?
Under the merged scheme, broadly a 20% expenditure credit on qualifying spend — staff costs, subcontractors, software, consumables. A company with £100,000 of qualifying spend sees a benefit in the region of £15,000–£16,000 after tax.
What if HMRC opens an enquiry?
Enquiry rates have risen sharply, which is why our narratives are written to answer HMRC's questions before they're asked. If an enquiry does open, we respond on your behalf — including for claims other advisers prepared.
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 "r&d claim 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 r&d claim?
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 notes our Isleworth clients ask about most
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 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.
People stay with the wrong accountant for years because switching feels disruptive. In practice the profession has a standard handover process — clearance letters, copies of prior returns and working papers — and the new firm drives it, not you.
If your last Self Assessment bill was over £1,000, HMRC usually asks for next year's tax in advance — half on 31 January, half on 31 July. It's the number-one cause of "why is my bill double?" calls, and it's manageable: if your income has dropped, the payments can be reduced with a claim.
Compare accountants on the things that bite later: is the fee fixed and written down, what exactly is included, who does the work, how fast do they answer in January. Proximity to Isleworth stopped being the differentiator the day filings went electronic.
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.
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.
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.
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.
