Worth knowing
Rules that come up in this work
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 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.
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.
Allowable expenses
Expense claims are where a return is won or lost in an enquiry. The test is wholly and exclusively for the trade; where a cost is mixed, the business proportion can be claimed if it can be identified. Capital items such as equipment and vans are relieved through capital allowances rather than as expenses, except under the cash basis where they are simply deducted when paid.
Employer National Insurance
The cost of an employee is more than the salary. Employer National Insurance at 15% above £5,000 a year, the 3% minimum pension contribution, holiday pay, equipment and management time all come on top. The Employment Allowance of £10,500 reduces the National Insurance for most employers with more than one person on the payroll.
Workplace pensions and auto-enrolment
Workplace pension compliance is part of payroll, not separate from it. Each pay period the payroll assesses who is eligible, calculates employer and employee contributions on qualifying earnings between the lower and upper thresholds, and sends the contribution file to the scheme. The minimum total is 8%, and many employers choose to contribute more as a recruitment advantage.
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.
Questions
Contractor Accountants questions from St. Margarets and North Twickenham
How are dividends documented?
Each dividend needs a board minute approving it and a dividend voucher recording the date, amount and shareholder. The company must have sufficient distributable profits after tax at the time. We check the reserves before each dividend, produce the paperwork and keep it on file, because undocumented dividends are reclassified by HMRC as salary or loans.
What is the flat rate VAT scheme and should I use it?
For most contractors with low costs the limited-cost-trader rate of 16.5% removes any advantage of the flat rate scheme, and the standard scheme reclaiming input VAT on equipment and software is better. Contractors with significant qualifying costs may differ. We calculate both at registration and review annually.
My client has put me inside IR35. Should I still use my company?
It can still be worth it if you have other outside-IR35 work, but for a single inside-IR35 engagement an umbrella company or direct PAYE is often simpler and cheaper. We run the comparison for your specific numbers and tell you honestly, even if the answer is that you do not need us for that contract.
Can I claim travel and subsistence?
For engagements outside IR35, travel to a client site that is a temporary workplace is claimable, subject to the 24-month rule: once you know an engagement will exceed 24 months at the same site, it stops being temporary. Subsistence follows the travel. Inside-IR35 engagements lose these claims. We check each engagement.
How should I pay myself from the company?
The usual approach is a salary around the National Insurance thresholds, which keeps your State Pension record intact and is deductible for Corporation Tax, with the rest as dividends taxed at the dividend rates after the £500 allowance. The exact split depends on your other income and the company's profit, and we set it at the start of each tax year.
What is IR35 and does it affect me?
IR35 asks whether, but for the company, you would be an employee of your client. If a contract is inside IR35 the income is taxed like employment. Since 2021 medium and large private-sector clients make the determination and deduct tax at source; for small clients the contractor decides. We review contracts and working practices and give a written opinion for £99.
