Worth knowing
Rules that come up in this work
Record keeping
Good records are the difference between a quick enquiry and a long one. For the self-employed, five years after the filing deadline; for companies, six years from the year end; for VAT, six years. Photographs of receipts, PDF statements and software exports all count. The requirement is to keep records, not paper, and a well-organised cloud folder satisfies it.
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.
Switching accountants
Changing accountant is simpler than most people fear. You authorise the new firm, which writes to the old one for professional clearance and your records; the outgoing accountant must hand over your own documents and usually does within two weeks. The new firm registers as your agent with HMRC and picks up the next filing. There is no need to wait for a year end.
CIS deductions
CIS turns construction subcontractors into advance taxpayers: a fifth of every labour payment goes to HMRC before they see it. Registering keeps the rate at 20% rather than 30%; gross payment status, for established businesses with a clean record, removes deductions altogether. The annual return is where the overpayment comes back, and filing it early brings the refund sooner.
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.
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
The £90,000 VAT threshold is measured over any twelve consecutive months, which is why a strong quarter can tip a business over unexpectedly. Registration must follow within thirty days of the end of the month the threshold was crossed. Below the threshold, voluntary registration is worth considering when customers are VAT-registered businesses and costs carry VAT.
Questions
Corporation Tax questions from Alton
Does R&D affect my Corporation Tax return?
Yes. Research and development relief is claimed on the CT600 and reduces the tax or generates a credit. Since the merged scheme, first-time claimants must notify HMRC within six months of the period end. Our R&D service prepares the technical report and the computation; the claim then goes on the return we file.
Can you deal with HMRC if they open an enquiry into the return?
Yes. As your authorised agent we receive and respond to HMRC correspondence. Routine queries about a return we filed are handled at no extra charge. A formal enquiry is handled through our HMRC investigation service at fixed fees per stage, so you know the cost before deciding how to proceed.
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.
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 the Corporation Tax rates for 2026/27?
Profits up to £50,000 are taxed at the 19% small profits rate. Profits above £250,000 pay the 25% main rate. Between the two, marginal relief produces an effective rate rising from 19% towards 25%, with a marginal rate of 26.5% on each pound in the band. The thresholds are divided by the number of associated companies plus one.
Is the CT600 included when you prepare the accounts?
Yes. Our limited company accounts packages at £299 and £449 include the computation, the CT600 and filing with HMRC. The standalone fees on this page are for companies whose accounts are prepared elsewhere or where the return needs separate work such as a capital allowances review.
