A UK limited company is not legally required to appoint an accountant.
However, most companies use an accountant to ensure compliance with HMRC and Companies House, avoid penalties, and manage tax efficiently.

An accountant helps with:

• Bookkeeping and reporting

• VAT, PAYE, and Corporation Tax compliance

• Annual accounts and tax returns

• Director remuneration and tax planning

For non-UK founders, professional accounting support is strongly recommended due to UK-specific rules.

UK limited companies must file:

• Annual accounts with Companies House (usually within 9 months of the accounting period end)

• Corporation Tax return (CT600) with HMRC (within 12 months of the period end)

• Corporation Tax payment is usually due 9 months and 1 day after the period end

Deadlines apply even if the company has no profit or limited activity.

Yes. If a director receives a salary, they must be registered on payroll and paid through PAYE.

Key points:

• Directors are treated as employees for payroll purposes

• Payroll is required even for sole directors

• If no salary is paid, payroll is not required solely due to directorship

Dividends are not paid through payroll.

Yes. We support director remuneration planning, including:

• PAYE salary setup

• Dividend planning and reporting

• Balancing salary and dividends tax-efficiently

• Ongoing compliance with HMRC rules

This is especially relevant for owner-managed UK limited companies and non-UK resident directors.

Non-UK resident directors may need to file a UK Self Assessment tax return, depending on:

• Whether they receive UK-source income

• Whether they are paid salary or director fees

• Applicable double taxation treaties

Each situation is assessed individually to determine UK tax obligations.

You must register for VAT if your UK taxable turnover exceeds £90,000 in a 12-month period.

You may also voluntarily register for VAT below the threshold, for example:

• To reclaim VAT on expenses

• When trading with VAT-registered customers

• For credibility with UK partners

VAT registration brings ongoing reporting and compliance obligations.
