Worth knowing

Rules that come up in this work

CIS deductions

The Construction Industry Scheme affects both sides of a construction payment. Contractors must verify subcontractors, deduct the right amount, issue statements and file monthly, with penalties from £100 for each late return. Subcontractors suffer deductions on turnover and recover the excess at the year end. Limited company subcontractors offset deductions against PAYE monthly instead.

Confirmation statements and identity verification

The confirmation statement is the annual check that the public register is right: officers, registered office, SIC codes, shareholders and the PSC register. It carries a £50 fee and no financial penalty for lateness, but failure to file leads to compulsory strike-off. The identity verification regime introduced in November 2025 has added a further check to every statement.

Director's loan accounts

Money taken from a company has to be something: salary, dividend, expense reimbursement or loan. If it is a loan and remains outstanding nine months after the year end, the company pays tax at the dividend higher rate on it until it is repaid. Clearing the balance with a properly declared dividend before the deadline, where reserves allow, is routine year-end work.

Salary versus dividends

Paying yourself from a company involves two routes with different tax treatment. Salary through payroll is a company expense and builds a National Insurance record; dividends come from post-tax profit at lower personal rates. Undocumented drawings that are neither become director's loans, with a 35.75% section 455 charge if not repaid within nine months of the year end.

Corporation Tax rates and marginal relief

Corporation Tax is not a flat rate. Profits to £50,000 pay 19%, profits above £250,000 pay 25%, and the band between is taxed at an effective marginal rate of 26.5% through the marginal relief mechanism. Associated companies share the thresholds, which catches directors who own more than one company and is the most common cause of underpaid tax in owner-managed groups.

The VAT registration threshold

Watching the rolling twelve-month turnover figure is one of the quiet jobs of monthly bookkeeping, because the £90,000 VAT threshold arrives silently. Crossing it brings quarterly returns, Making Tax Digital software and a decision about schemes. Crossing it late brings a bill for VAT you could not recover from customers and a penalty for failing to notify.

Making Tax Digital for Income Tax

MTD for Income Tax replaces one annual return with quarterly digital updates and a year-end declaration, submitted from software. The threshold is gross trading and property income, measured two years earlier, and started at £50,000 in April 2026 before falling to £30,000 in April 2027. Anyone affected needs digital record keeping in place before their start date, not after.

Questions

R&D Tax Credits questions from Deptford Creek

How far back can I claim?

A claim can be made up to two years after the end of the accounting period, by amending the CT600. If you have two open periods both can be claimed. The notification rule applies to the later periods if you have not claimed recently, so the two-year window and the six-month window interact; we check both.

Does claiming R&D relief increase my chance of an enquiry?

HMRC now checks a far higher proportion of claims than before 2023, so any claim carries some risk of questions. A claim with a clear technical narrative, costs that reconcile to the accounts and payroll, and a named competent professional behind it is answered quickly. We write claims to that standard.

Can I claim for subcontracted work?

Under the merged scheme the company that decides to undertake the R&D and bears the risk generally claims, even if it subcontracts the work. Subcontractor costs are included at 65%. Overseas subcontractor and worker costs are largely excluded unless the conditions cannot be met in the UK. We apply the rules to your contracts.

What if HMRC opens an enquiry into an existing claim?

We review the claim, the narrative and the cost basis, tell you how robust it is, and quote a fixed fee for handling the enquiry before any work starts. Where a claim was overstated by a previous adviser, the best outcome is often an agreed reduction, and we say so rather than fight a losing position at your expense.

What counts as R&D for tax purposes?

A project seeking an advance in overall knowledge or capability in a field of science or technology, through the resolution of scientific or technological uncertainty that a competent professional in the field could not readily resolve. Commercial novelty is not enough; routine development with known methods is not enough. The test is about the technology, not the product.

Why is the eligibility review free?

Because a large share of enquiries do not qualify, and we would rather tell you that for nothing than charge £999 for a claim HMRC rejects. The review takes a short call and some questions about the projects. You get a written view: qualifies, does not qualify, or borderline with the reasons. There is no obligation afterwards.

Is r&d tax credits in Deptford Creek really the same price as elsewhere?

Yes. The fee published on this page is what a client in Deptford Creek pays and what a client in any other part of England pays. It is confirmed in writing before work starts and the invoice matches the quote. Where a higher package applies because your situation is more complex, we say so at the quote stage, never afterwards.

No. IGI Accounting is an online-only firm. We serve Deptford Creek and every other UK postcode remotely, with records sent by WhatsApp or email and everything filed electronically. The absence of local premises is why the fee for r&d tax credits is the same in Deptford Creek as anywhere else in the country, and why there is nothing to visit and nothing to print.
