Hi Pavel,
Limited companies that are incorporated in the UK are normally subject to orporation Tax on their worldwide profits.
UK-incorporated company is, with certain exceptions, resident in the UK for tax purposes.
Companies may also be required to register for value-added tax (VAT) and pay-as-you-earn (PAYE).
You can find HMRC guidance on each of these topics by going to:

Thank you.
