Worth knowing
Rules that come up in this work
Allowable expenses
An expense is allowable against trading profit if it is incurred wholly and exclusively for the business. Materials, business travel other than ordinary commuting, a proportion of home running costs, software, insurance, professional fees, bank charges and protective clothing qualify. Client entertainment, ordinary clothing, fines and the private share of mixed-use costs do not.
Record keeping
Record keeping is a legal obligation with a penalty of up to £3,000 for failure, but its real value is in making every other filing cheaper and more defensible. Keep invoices, receipts, bank statements, mileage logs and any HMRC correspondence, digitally if you like, for five years after the relevant filing deadline for individuals and six years for companies and VAT.
The 60-day property CGT return
Selling UK residential property that was not your main home for the whole period of ownership triggers a separate Capital Gains Tax return, due within 60 days of completion along with payment of the tax. This is in addition to the annual Self Assessment. The gain is taxed at 18% or 24% depending on your income band, after the £3,000 annual exempt amount.
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.
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.
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.
Workplace pensions and auto-enrolment
Every employer must assess its workers for automatic enrolment from the first employee's start date. Those aged 22 to State Pension age earning over £10,000 a year must be enrolled into a qualifying pension with minimum contributions of 8% of qualifying earnings, at least 3% from the employer, and a declaration of compliance made to the Pensions Regulator within five months.
Questions
Corporation Tax questions from Cranfield
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.
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 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.
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.
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.
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.
Is corporation tax in Cranfield really the same price as elsewhere?
Yes. The fee published on this page is what a client in Cranfield 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.
Do you have an office in Cranfield?
No. IGI Accounting is an online-only firm. We serve Cranfield 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 Cranfield as anywhere else in the country, and why there is nothing to visit and nothing to print.
