Local facts
About Omagh
Omagh is in Northern Ireland, in the BT78 postcode district, Northern Ireland. Northern Ireland uses the same income tax, National Insurance and Corporation Tax rates as Great Britain, and companies file with Companies House on the Belfast register. Stamp Duty Land Tax applies to property. For goods, the Windsor Framework means some EU VAT rules apply to trade with the EU, which affects businesses moving goods across the border.

Worth knowing
Rules that come up in this work
Switching accountants
You can switch accountant at any point in the year. The new firm requests clearance and your records from the old one, which cannot withhold your own documents though it may hold its own working papers until its fees are settled. Agent authorisations with HMRC and Companies House are transferred, and the next deadline is picked up without a gap.
Closing a company
Voluntary strike-off is available only to solvent companies. One that owes money it cannot pay needs a creditors' voluntary liquidation through a licensed insolvency practitioner, and directors who dissolve an insolvent company face personal consequences. For a solvent company the process takes three to four months from filing the DS01, with notice to creditors and shareholders within seven days.
Employer National Insurance
Employers pay National Insurance at 15% on each employee's earnings above the £5,000 secondary threshold, following the April 2025 changes. The Employment Allowance offsets up to £10,500 of this for eligible employers, which for a small team often removes the liability entirely, but companies where the director is the only employee do not qualify.
Workplace pensions and auto-enrolment
Auto-enrolment duties begin the day you take on your first employee, not when the Pensions Regulator writes to you. Eligible staff must be enrolled, contributions paid every pay period and re-enrolment carried out every three years. Director-only companies without employment contracts are usually exempt. Fines for non-compliance are fixed and escalating.
Dormant companies
A dormant company is one with no significant accounting transactions in the year, where the only permitted entries are the payment for shares on incorporation, Companies House fees and penalties. It still files a confirmation statement and simplified dormant accounts every year. A bank charge or an accountant's fee paid from the company ends dormancy and requires full accounts.
The trading and property allowances
The first £1,000 of trading income and, separately, the first £1,000 of property income each year is tax free under the trading and property allowances. Below those figures no return is needed for that income. Above them you can deduct the £1,000 allowance instead of actual expenses if that is better, which suits side businesses and single-room lets with few costs.
Crypto records and reporting
Crypto tax splits into capital gains on disposals and income on rewards, with different rates and different reporting. The £3,000 annual exempt amount and the 18% and 24% rates apply to gains; staking, mining and airdrop income is taxed at marginal income tax rates. HMRC's nudge letters to holders have increased sharply, and a voluntary disclosure before one arrives is treated far more leniently.
Questions
CIS Tax Returns questions from Omagh
Can my CIS deductions be set against my VAT or other taxes?
For sole traders, no; CIS deductions are credited against your income tax and Class 4 National Insurance through Self Assessment, with the excess refunded. For companies, deductions are offset against PAYE and CIS owed, and the remaining balance is repaid by HMRC after the year end or, on request, set against Corporation Tax.
I have not filed for several years. Can you catch me up?
Yes. Late Self Assessment returns can be filed for the last four tax years to reclaim CIS deductions, and HMRC will offset refunds against any penalties. We quote a fixed fee for the set based on the number of years and reconcile each year's statements. The sooner this is done the more years remain claimable.
What counts as construction work under CIS?
Site preparation, building, alteration, repair, decoration, demolition, and installing systems such as heating, lighting and water. Professional work such as architecture and surveying, scaffolding hire without labour, and carpet fitting are outside the scheme. Mixed contracts fall within it entirely. We check borderline cases against HMRC's list.
What records do I need to keep for CIS?
Subcontractors: every deduction statement, invoices and bank records. Contractors: verification references, gross payments, materials costs, deductions made and the statements issued, for at least three years. Missing deduction statements are the most common reason refunds are delayed, so we help you obtain copies from contractors.
When are contractor returns due?
The CIS300 monthly return covers the tax month to the 5th and must reach HMRC by the 19th. Deduction statements must go to subcontractors by the same date. A nil return is still required if you paid no subcontractors. Late returns cost £100 immediately, rising to £200 after two months and then percentage-based penalties.
What rate do I deduct from a subcontractor?
You must verify each new subcontractor with HMRC before the first payment. HMRC tells you 20% if they are registered, 30% if not, or 0% if they hold gross payment status. Deductions apply to the labour element only, never to materials, VAT or plant hire. We verify every new subcontractor and record the result.
Do you have an office in Omagh?
No. IGI Accounting is an online-only firm. We serve Omagh 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 cis tax returns is the same in Omagh as anywhere else in the country, and why there is nothing to visit and nothing to print.
Is cis tax returns in Omagh really the same price as elsewhere?
Yes. The fee published on this page is what a client in Omagh 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.
