Worth knowing
Rules that come up in this work
Payments on account
Payments on account catch out most people in their second year of self-employment. HMRC assumes next year's tax will match this year's and collects half in January and half in July, in advance, on top of the balancing payment. If profits are dropping you can apply to reduce them, but reducing them too far attracts interest. We calculate the right figure rather than guessing.
The Self Assessment calendar
Self Assessment runs on a fixed annual cycle. Registration by 5 October following the tax year, online filing and payment by 31 January, and a second instalment on 31 July for those making payments on account. The penalties for lateness are automatic and escalate monthly, which is why we file early and chase approvals well before the window closes.
Making Tax Digital for Income Tax
MTD for Income Tax replaces one annual return with quarterly digital updates and a year-end declaration, submitted from software. The threshold is gross trading and property income, measured two years earlier, and started at £50,000 in April 2026 before falling to £30,000 in April 2027. Anyone affected needs digital record keeping in place before their start date, not after.
Late filing penalties
HMRC's penalties for a late Self Assessment return are automatic: £100 the day after 31 January, £10 a day from three months late up to £900, then the greater of £300 or 5% of the tax at six and twelve months. Interest and separate late-payment penalties apply to the tax itself. Companies House charges £150 to £1,500 for late accounts, doubling for a second consecutive year.
Corporation Tax rates and marginal relief
Corporation Tax is not a flat rate. Profits to £50,000 pay 19%, profits above £250,000 pay 25%, and the band between is taxed at an effective marginal rate of 26.5% through the marginal relief mechanism. Associated companies share the thresholds, which catches directors who own more than one company and is the most common cause of underpaid tax in owner-managed groups.
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.
Director's loan accounts
A director's loan account records money moving between a director and the company that is not salary or dividend. If the director owes the company money nine months and one day after the year end, the company pays section 455 tax at 35.75% of the balance, refundable only when the loan is repaid. Loans over £10,000 are also a benefit in kind unless interest is charged at HMRC's official rate.
Questions
Freelancer Accountants questions from Seething Wells
I have a job and freelance on the side. How does that work?
Your employment is taxed through PAYE and your freelance profit is added on top through Self Assessment, usually at your marginal rate. If freelance income is under £1,000 the trading allowance means no return is needed. Above that, register by 5 October after the tax year you started. Our package covers the whole return including the employment pages.
Can I claim for my laptop and camera?
Yes. Equipment used for the business qualifies for capital allowances, usually the annual investment allowance giving full relief in the year of purchase, restricted for private use. Under the cash basis equipment is simply an expense when paid. Items bought before you started can be brought in at market value.
What expenses can freelancers claim?
A proportion of home costs for the space and hours you work there, or HMRC's flat rate; equipment and software; professional subscriptions and insurance; training that maintains existing skills; business travel other than commuting; marketing and website costs; bank charges; and the business share of phone and internet. We review your categories every month.
How much should I set aside for tax?
For a sole trader, roughly 20% to 30% of profit covers income tax and Class 4 National Insurance at basic rate, more at higher rate, plus payments on account in the first year they apply. We give you a specific monthly figure based on your actual profit each month, which is more useful than a rule of thumb.
What is the annual-only option?
For £229 a year we prepare your year-end accounts and Self Assessment from the records you keep yourself, whether in software or a spreadsheet. It suits freelancers with modest transaction volumes who are organised. If the records arrive as a shoebox, the sole trader accounts shoebox fee applies instead.
Should I be a sole trader or a limited company?
At profits under roughly £30,000 to £40,000 a sole trader is simpler and the tax saving from a company is small after the extra compliance cost. Above that, or where clients prefer to contract with a company or liability is a concern, incorporation can make sense. Our free comparison tool gives a first view and the starter session a definitive one.
