Worth knowing
Rules that come up in this work
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
A solvent company that has finished its purpose can be dissolved by voluntary strike-off: form DS01 with a £13 Companies House fee, after three months without trading and with all debts paid, final accounts and tax return filed, and assets distributed. HMRC objects to any application where returns or tax are outstanding, so the sequence matters more than the form.
Employer National Insurance
Since April 2025 employer National Insurance has been 15% on earnings above a £5,000 secondary threshold, a substantial increase for small employers. The Employment Allowance rose to £10,500 at the same time to soften it for the smallest businesses. Directors deciding their own salary weigh this cost against the Corporation Tax deduction a salary provides.
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
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
Small side incomes are covered by two £1,000 allowances, one for trading and one for property, which remove the need to register or report income below that level. Once income exceeds £1,000, the allowance can be used in place of expenses, a choice worth making deliberately: a freelancer with £900 of costs is better off with the allowance, one with £3,000 is not.
Crypto records and reporting
HMRC treats cryptoassets as property. Swapping one token for another, spending crypto or gifting it are all disposals for Capital Gains Tax, and staking and lending rewards are income. Gains are computed under pooling rules with same-day and 30-day matching. From 2026 HMRC receives data from exchanges worldwide under the Cryptoasset Reporting Framework, so unreported activity is increasingly visible.
Questions
Corporation Tax questions from Waterhay
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.
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.
What is iXBRL and do I need to worry about it?
HMRC requires the accounts and computation attached to a CT600 to be tagged in iXBRL, a machine-readable format. We produce and validate the tagged files as part of the service. If another firm prepared your accounts we tag their figures; you never deal with it directly.
My CT600 is overdue. What now?
The £279 rescue fee gets it prepared and filed quickly from your accounts. The £100 late penalty is fixed, rising to £200 after three months and then to tax-geared penalties at six and twelve months, so speed matters. If there is a reasonable excuse we draft the appeal as part of the fee.
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.
Do you have an office in Waterhay?
No. IGI Accounting is an online-only firm. We serve Waterhay 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 corporation tax is the same in Waterhay as anywhere else in the country, and why there is nothing to visit and nothing to print.
Is corporation tax in Waterhay really the same price as elsewhere?
Yes. The fee published on this page is what a client in Waterhay pays and what a client in any other part of England 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.
