Worth knowing
Rules that come up in this work
The 60-day property CGT return
The 60-day Capital Gains Tax return on residential property is the deadline landlords most often miss, because it falls outside the Self Assessment cycle and runs from completion, not exchange. Private residence relief for periods you lived in the property, plus the final nine months, reduces the gain. Penalties for a late return mirror Self Assessment, starting at £100.
Crypto records and reporting
Crypto tax splits into capital gains on disposals and income on rewards, with different rates and different reporting. The £3,000 annual exempt amount and the 18% and 24% rates apply to gains; staking, mining and airdrop income is taxed at marginal income tax rates. HMRC's nudge letters to holders have increased sharply, and a voluntary disclosure before one arrives is treated far more leniently.
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
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.
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.
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.
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.
Questions
Startup Accountants questions from Seething Wells
What if the startup fails?
Then the company needs to be closed properly: final accounts, final CT600, deregistration from VAT and PAYE, and a strike-off application or, if there are debts it cannot pay, a formal insolvency process. Our strike-off service with final accounts is from £349. SEIS investors can claim loss relief, which softens their outcome.
Can I switch to you from another accountant mid-year?
Yes. We request your records and professional clearance from the previous firm, pick up the bookkeeping where they left off and take over the filings. There is no charge for the switch and the first month's fee is the same as any other.
Can I claim startup costs incurred before incorporation?
Yes. Pre-trading expenses incurred up to seven years before the company started trading, which would have been deductible if incurred while trading, are treated as incurred on the first day of trading. Keep the receipts. Equipment you bring in can be transferred to the company at market value.
When are a new company's first filings due?
The first confirmation statement is due within 14 days of the first anniversary of incorporation. The first accounts are due 21 months after incorporation. Corporation Tax is due nine months and one day after the first accounting period ends, and the first period is often longer than a year, which creates two CT600s. We handle the split.
What are the SEIS limits?
A company can raise up to £250,000 under SEIS within the first three years of trading, with gross assets under £350,000 and fewer than 25 employees. EIS allows up to £5 million a year and £12 million in total, for companies under seven years old with fewer than 250 employees. Trading activities must qualify; some are excluded.
What is SEIS/EIS advance assurance and do I need it?
Investors in qualifying early-stage companies get income tax relief of 50% (SEIS) or 30% (EIS) and capital gains exemptions, which makes raising much easier. Advance assurance is HMRC's confirmation in principle that your company qualifies, and most angel investors insist on it. Our £299 service prepares and submits the application.
