Worth knowing

Rules that come up in this work

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

A dormant company is one with no significant accounting transactions in the year, where the only permitted entries are the payment for shares on incorporation, Companies House fees and penalties. It still files a confirmation statement and simplified dormant accounts every year. A bank charge or an accountant's fee paid from the company ends dormancy and requires full accounts.

The trading and property allowances

The first £1,000 of trading income and, separately, the first £1,000 of property income each year is tax free under the trading and property allowances. Below those figures no return is needed for that income. Above them you can deduct the £1,000 allowance instead of actual expenses if that is better, which suits side businesses and single-room lets with few costs.

Crypto records and reporting

Most crypto holders have taxable events they do not recognise, because every swap is a disposal even when no pounds change hands. The computation requires the complete transaction history from every exchange and wallet, pooled by asset with HMRC's matching rules applied. Exchange-generated tax reports are frequently wrong because they cannot see transfers between a user's own wallets.

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

HMRC requires records of all income and expenses, bank statements, invoices and receipts to be kept for at least five years after the 31 January filing deadline of the tax year they relate to, and companies must keep records for six years from the end of the accounting period. Digital copies are acceptable. Under Making Tax Digital the records must be kept in compatible software.

Questions

Freelancer Accountants questions from Mansion House

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.

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.

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.

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.

What does the £45 sole trader package include?

Monthly bookkeeping from your bank feed with receipts captured by phone, a monthly summary showing profit and the tax accruing, your Self Assessment with the self-employment pages prepared and filed, payments on account calculated, and deadline tracking. Software is in your name and billed to you separately.

What does the £79 company package include?

Monthly bookkeeping, director payroll with RTI submissions, dividend paperwork, the annual statutory accounts and CT600 filed with Companies House and HMRC, the confirmation statement filed (Companies House £50 fee separate), and deadline tracking. Your personal Self Assessment is added at the published £129 if needed.
