No hourly rate and no surprise invoice. The Wrythe clients know the fee for freelancer accountants before they send a single document, and it stays fixed.

Online only, UK based. There is no office in The Wrythe to pay for, which is why the fee is the same here as anywhere in England; the work is done by people in the UK who answer the same day.

Worth knowing

Rules that come up in this work

Payments on account

A common surprise in Self Assessment is the January payment that is far larger than expected. That is the balancing payment for the year just ended plus the first payment on account for the year ahead, which HMRC sets at half of the bill just calculated. We put the figure in your hands months ahead and tell you how to adjust it legitimately when circumstances change.

The Self Assessment calendar

Four dates govern Self Assessment: 5 October to register, 31 October for paper returns, 31 January to file online and pay, and 31 July for the second payment on account. Missing the January date triggers an automatic £100 penalty before any tax is even considered, so we treat it as the fixed point around which the rest of the year is planned.

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.

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

Companies pay Corporation Tax at 19% on profits up to £50,000 and 25% on profits over £250,000. Between those figures marginal relief applies, producing an effective rate that rises gradually and a marginal rate of 26.5% on each pound in the band. The thresholds are divided by the number of associated companies, so a director with two companies has thresholds of £25,000 and £125,000 for each.

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

The most common tax problem in owner-managed companies is an overdrawn director's loan account: drawings taken during the year that were never declared as dividends or salary. The company faces a 35.75% charge on the balance outstanding nine months after the year end, and the director may have a benefit in kind. We review the account before every year end to clear it properly.

Questions

Freelancer Accountants questions from The Wrythe

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.
