Local facts
About Clydach Vale
Clydach Vale is in Wales, Wales. Welsh taxpayers pay Welsh rates of income tax, set by the Senedd and currently matching the English bands, collected under a C-prefixed tax code. 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
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
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.
Making Tax Digital for Income Tax
The biggest change to Self Assessment in a generation is Making Tax Digital for Income Tax, now live for higher-earning sole traders and landlords and arriving for the rest in stages. Quarterly updates are due by 7 August, 7 November, 7 February and 7 May, built from digital records. The practical consequence is that spreadsheet-and-shoebox bookkeeping is ending for anyone above the threshold.
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.
Payments on account
Payments on account catch out most people in their second year of self-employment. HMRC assumes next year's tax will match this year's and collects half in January and half in July, in advance, on top of the balancing payment. If profits are dropping you can apply to reduce them, but reducing them too far attracts interest. We calculate the right figure rather than guessing.
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.
Questions
Corporation Tax questions from Clydach Vale
Are dividends and salary treated differently for Corporation Tax?
Yes. Salary, employer National Insurance and employer pension contributions are deductible expenses that reduce taxable profit. Dividends are paid from profit after tax and are not deductible. This asymmetry is central to the salary-versus-dividend planning we do for directors.
What expenses are not allowed for Corporation Tax?
Business entertainment of customers, most fines and penalties, depreciation (replaced by capital allowances), general provisions, and the private element of mixed-use costs. Legal fees on capital items are also disallowed. The computation adds these back to accounting profit and we list every adjustment so you can see the effect.
My company made a loss. What can be done with it?
A trading loss can be set against the company's other profits of the same year, carried back one year for a repayment of tax already paid, or carried forward against future profits. The right choice depends on cash flow and expected profits. We model the options and make the claim on the return.
What are associated companies and why do they matter?
Companies under common control count as associated, and the £50,000 and £250,000 thresholds are divided between them. A director who owns two companies has thresholds of £25,000 and £125,000 for each. Missing this is a common error that produces an underpayment and interest.
When is Corporation Tax paid and the return filed?
Tax is due nine months and one day after the end of the accounting period; the CT600 is due twelve months after it. Companies with profits over £1.5 million pay by instalments instead. Interest runs on late payment from the due date, and a late return attracts a £100 penalty rising to 10% of the tax at twelve months.
What are capital allowances and what can I claim?
Capital allowances are the tax equivalent of depreciation. The annual investment allowance gives 100% relief on up to £1 million of qualifying plant and machinery a year; full expensing gives 100% on new main-rate assets without limit; cars and integral features go into pools at 18% or 6%. The £299 package reviews every asset purchase in the year.

No. IGI Accounting is an online-only firm. We serve Clydach Vale and every other UK postcode remotely, with records sent by WhatsApp or email and everything filed electronically.

Is corporation tax in Clydach Vale really the same price as elsewhere?
Yes. The fee published on this page is what a client in Clydach Vale 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.
