If your business is based in the UK, you must pay Corporation Tax on all profits from the UK and abroad.
If your business isn't based in the UK but has an office or branch here, you will only pay Corporation Tax on profits from UK activities.
You'll need to register to pay tax within 3 months of starting to do business. This includes buying, selling, advertising, renting a property and employing someone.
Value Added Tax
You must register for Value Added Tax (VAT) with HMRC if your business' taxable turnover is more than £85,000. You'll need to do this within 30 days of the end of the month when you went over this amount.
VAT is a tax added to most products and services sold by VAT-registered businesses.
