Worth knowing
Rules that come up in this work
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
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.
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.
The 60-day property CGT return
Since April 2020 a gain on UK residential property must be reported and the tax paid within 60 days of completion through HMRC's dedicated service, separately from the annual return. Non-residents must report all UK land disposals in the same window whether or not tax is due. Getting the computation right first time matters because the figure is then carried into the Self Assessment.
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.
Corporation Tax rates and marginal relief
Since April 2023 there have been two Corporation Tax rates, 19% small profits and 25% main, with marginal relief smoothing the transition between £50,000 and £250,000 of profit. The band is where planning matters: each pound of profit in it is taxed at an effective 26.5%, so pension contributions and capital expenditure timed to keep profit below £50,000 are worth more than they look.
Salary versus dividends
Directors of their own companies usually take a salary at or just above the National Insurance thresholds, which keeps the year qualifying for State Pension and is deductible for Corporation Tax, with further income as dividends. Dividends above the £500 allowance are taxed at 10.75%, 35.75% and 39.35% by band and can only be paid from distributable profits after tax, with a minute and voucher each time.
Questions
Contractor Accountants questions from London
I am about to leave permanent employment to contract. Where do I start?
With the company formation and the first contract review. Our £99 formation-plus-registrations package sets up the company with Corporation Tax and PAYE registered; the IR35 review of your first engagement decides how the income will be taxed. Join the Essential package from the month you start invoicing.
Do I need business insurance?
Most client contracts require professional indemnity and public liability cover, and employer's liability is a legal requirement if the company employs anyone other than the director. Insurance is not something we sell, but we tell you what your contracts require and the premiums are deductible for Corporation Tax.
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 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.
Which deadlines matter most for contractor accountants?
The next four dates that apply to contractor accountants are shown at the top of this page, calculated from today. For London clients we diarise every one of them from the day you join and send reminders before each, so the work is done in good time rather than in the last week before a penalty.
