UK Tax FAQ

Common questions.

What rate of Corporation Tax will my company pay?

Profits up to £50,000 are taxed at the 19% small profits rate and profits above £250,000 at the 25% main rate, with marginal relief in between. These limits are shared between associated companies and reduced for short accounting periods.

When are Corporation Tax payments and returns due?

For most companies, tax is payable 9 months and 1 day after the end of the accounting period, and the CT600 return is due 12 months after the period ends. Large companies pay by quarterly instalments.

When must my business register for VAT?

Registration is required when VAT-taxable turnover exceeds £90,000 in any rolling 12-month period, or is expected to in the next 30 days. Voluntary registration is possible below the threshold.

Do VAT returns have to be filed through Making Tax Digital?

Yes. VAT-registered businesses must keep digital records and submit VAT returns using MTD-compatible software. We file through cloud tools such as Xero, QuickBooks and Zoho.

Can you coordinate my UK, US, India and UAE taxes?

Yes. Our team covers all four jurisdictions, so cross-border income, residence and treaty positions are planned together rather than in isolation.
