Worth knowing
Rules that come up in this work
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.
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.
Salary versus dividends
Paying yourself from a company involves two routes with different tax treatment. Salary through payroll is a company expense and builds a National Insurance record; dividends come from post-tax profit at lower personal rates. Undocumented drawings that are neither become director's loans, with a 35.75% section 455 charge if not repaid within nine months of the year end.
Payments on account
If your Self Assessment bill exceeds £1,000 and less than 80% of your tax was collected at source, HMRC asks for two advance payments towards the following year, each half of the current bill, due 31 January and 31 July. The first year this happens the January payment is effectively one and a half times the bill. We model it in advance and show you how to reduce the payments if income is falling.
The Self Assessment calendar
The tax year runs from 6 April to 5 April. Anyone new to Self Assessment must register by 5 October after the end of the tax year in which their untaxed income began. The online return and the balancing payment are due by 31 January, with a second payment on account on 31 July where they apply. Paper returns have an earlier deadline of 31 October and are rarely sensible.
Making Tax Digital for Income Tax
The biggest change to Self Assessment in a generation is Making Tax Digital for Income Tax, now live for higher-earning sole traders and landlords and arriving for the rest in stages. Quarterly updates are due by 7 August, 7 November, 7 February and 7 May, built from digital records. The practical consequence is that spreadsheet-and-shoebox bookkeeping is ending for anyone above the threshold.
Questions
Freelancer Accountants questions from Trinity
How do you handle irregular and overseas income?
Irregular income is normal for freelancers and the monthly summary shows the year-to-date position so lean months are planned for. Overseas clients are invoiced without UK VAT in most cases, and any foreign tax withheld can usually be credited against your UK liability. Both are handled within the package.
Do I need to register for VAT?
Only when your taxable turnover in any rolling 12 months exceeds £90,000, or voluntarily before that. Many freelancers with business clients register voluntarily to reclaim VAT on equipment; those with consumer clients usually wait. We monitor your rolling turnover and advise before the threshold is reached.
Does Making Tax Digital apply to freelancers?
If your gross self-employment plus property income was over £50,000 in 2024/25 you joined MTD for Income Tax in April 2026; over £30,000 means April 2027; over £20,000 is planned for April 2028. It means digital records and quarterly updates. Our monthly package keeps the records in the right form and submits the updates.
What is the starter session?
A £99 video call before or soon after you go freelance, covering the sole trader versus company decision, registration with HMRC, how to price so that tax is covered, what records to keep and how, invoicing and payment terms, and the dates that matter. You come away with a written plan. If you then join a monthly package the £99 is credited.
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.
