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

Companies House has tightened its requirements under the Economic Crime and Corporate Transparency Act: every company needs a registered email address and an appropriate registered office, every statement includes a lawful-purpose declaration, and every director and PSC must verify their identity. The confirmation statement, due annually with a £50 fee, is where most of this is confirmed.

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.

Late filing penalties

Penalties are the clearest reason to work to deadlines. A Self Assessment return one day late costs £100 regardless of whether any tax is due; three months late adds £10 a day. Late company accounts start at £150 and reach £1,500, and double if the previous year was also late. None of this is negotiable afterwards except through a narrow reasonable-excuse appeal.

Payments on account

A common surprise in Self Assessment is the January payment that is far larger than expected. That is the balancing payment for the year just ended plus the first payment on account for the year ahead, which HMRC sets at half of the bill just calculated. We put the figure in your hands months ahead and tell you how to adjust it legitimately when circumstances change.

The Self Assessment calendar

Self Assessment runs on a fixed annual cycle. Registration by 5 October following the tax year, online filing and payment by 31 January, and a second instalment on 31 July for those making payments on account. The penalties for lateness are automatic and escalate monthly, which is why we file early and chase approvals well before the window closes.

Director's loan accounts

A director's loan account records money moving between a director and the company that is not salary or dividend. If the director owes the company money nine months and one day after the year end, the company pays section 455 tax at 35.75% of the balance, refundable only when the loan is repaid. Loans over £10,000 are also a benefit in kind unless interest is charged at HMRC's official rate.

Questions

R&D Tax Credits questions from Lisburn

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.

What is the Additional Information Form?

Since August 2023 every R&D claim must be accompanied by a form submitted to HMRC before the CT600, giving project descriptions, cost breakdowns, the named senior officer responsible and any agent involved. Claims without it are removed from the return. We complete and submit it as part of the £999 fee.

What is the advance notification requirement?

Companies that have not claimed in the previous three accounting periods must notify HMRC of their intention to claim within six months of the end of the period. Miss it and the claim for that period is lost entirely. We check your position at the eligibility stage and file the notification as part of the service.

Why do you charge a fixed fee rather than a percentage?

Percentage fees reward inflating the claim, which is exactly what HMRC's campaign targets. A fixed fee means our only interest is a claim that is right. For most small company claims £999 is also considerably cheaper than the 15% to 30% of benefit that contingent advisers charge.

How long does a claim take to pay out?

HMRC aims to process 85% of claims within 40 days but the compliance campaign has lengthened this for many. Relief reducing a Corporation Tax bill takes effect when the return is processed; payable credits are paid to the company's bank account. We track the claim and chase HMRC if it stalls.

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

Yes. The fee published on this page is what a client in Lisburn pays and what a client in any other part of Northern Ireland 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.

Do you have an office in Lisburn?

No. IGI Accounting is an online-only firm. We serve Lisburn 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 Lisburn as anywhere else in the country, and why there is nothing to visit and nothing to print.
