Common questions about UK LTD tax
Do I pay UK tax even if I live outside the UK?
The UK company is generally taxed in the UK on its profits. Your personal position is separate and may interact with tax treaties.
How is taxable profit calculated?
Taxable profit is generally revenue minus allowable business expenses.
What is marginal relief?
It softens the jump between the lower and higher corporation tax bands as profits move upward.
Should I use a UK accountant?
Yes. A UK accountant is the safest route for annual filings and bookkeeping structure.
Do I need VAT registration?
Only when you cross the relevant threshold, unless you choose to register voluntarily earlier.
