About Thornhill, Caerphilly

National Insurance, VAT and Corporation Tax are UK-wide. Property purchases in Wales pay Land Transaction Tax to the Welsh Revenue Authority rather than Stamp Duty, with its own bands and rates.

Worth knowing
Rules that come up in this work
Dormant companies
Companies formed to protect a name or hold a future business are dormant but not exempt: Companies House still expects dormant accounts within nine months of the year end and a confirmation statement annually with its £50 fee, and HMRC must be told the company is dormant or it will demand Corporation Tax returns. The filings are short, but the penalties for missing them are the same as for a trading company.
The trading and property allowances
Not every small income needs a tax return. The trading allowance exempts the first £1,000 of self-employment or casual income and the property allowance does the same for rental income, each measured on gross receipts. They cannot be combined with rent-a-room relief on the same income, and claiming the allowance means giving up the expense deduction for that source.
Switching accountants
The main reasons people switch accountant are surprise invoices, missed deadlines and not understanding what they are being told. Switching involves a clearance letter between the firms, a transfer of records and agent authorisations, and a short handover of the current position. It takes about two weeks and should cost nothing extra.
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.
Confirmation statements and identity verification
Every company must file a confirmation statement at least once a year, within fourteen days of its review date, with a £50 Companies House fee. Since November 2025 directors and people with significant control must also verify their identity with Companies House, and the confirmation statement is where existing officers confirm they have done so during the transition year.
CIS deductions
Under the Construction Industry Scheme, contractors deduct 20% from a registered subcontractor's labour invoices, or 30% if unregistered, and pay it to HMRC. The subcontractor reclaims the deductions against their actual tax through Self Assessment, usually producing a refund because deductions are on turnover while tax is on profit. Contractors file a monthly return by the 19th.
Late filing penalties
HMRC's penalties for a late Self Assessment return are automatic: £100 the day after 31 January, £10 a day from three months late up to £900, then the greater of £300 or 5% of the tax at six and twelve months. Interest and separate late-payment penalties apply to the tax itself. Companies House charges £150 to £1,500 for late accounts, doubling for a second consecutive year.
Questions
Company Formation questions from Thornhill
Does the company need to register for Corporation Tax?
Yes, within three months of starting to trade. HMRC usually issues the company's Unique Taxpayer Reference by post shortly after incorporation. Registration for Corporation Tax is included in our £99 package and above; the formation-only package leaves it to you, and we tell you how.
When should I register for VAT and PAYE?
VAT when taxable turnover will exceed £90,000 in a rolling 12 months, or voluntarily before if it helps. PAYE before the first salary payment, including to yourself as director. Both are included in the £99 package or available separately at £49 each.
What share structure should I have?
For a single founder, one ordinary share of £1 is usual. For two or more, the split should reflect the agreed ownership and may use different share classes to allow different dividend payments. We discuss this before filing, because changing it later needs resolutions and filings. We also advise on whether a shareholders' agreement is worth having.
What is a SIC code and which one do I need?
The Standard Industrial Classification code describes what the company does and appears on the public register. You can have up to four. We pick the right ones from the official list for your trade. Changing them later is done through the confirmation statement, which is our £39 SIC change service.
Do directors need to verify their identity?
Yes. Since 18 November 2025 every new director and person with significant control must verify their identity with Companies House before or at incorporation, through GOV.UK One Login or an authorised agent. We tell you exactly how to do it and check that the verification is linked before we file.
Can I use my home address?
You can, but it becomes public on the Companies House register as the registered office and as your service address. Most founders prefer not to. Our registered office service at £69 a year provides a London address for official post, and the £149 formation package includes the first year.
Do you have an office in Thornhill?
No. IGI Accounting is an online-only firm. We serve Thornhill, Caerphilly 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 company formation is the same in Thornhill as anywhere else in the country, and why there is nothing to visit and nothing to print.
Is company formation in Thornhill really the same price as elsewhere?
Yes. The fee published on this page is what a client in Thornhill, Caerphilly pays and what a client in any other part of Wales 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.
