Tax Tips

• Income from overseas clients is taxable in the UK if you are UK resident — report it in sterling using HMRC's exchange rates at the date of payment.
• If you provide services to overseas businesses, those services may be zero-rated for UK VAT purposes — check the place of supply rules carefully.
• CIoL and ITI membership fees are fully allowable — professional body subscriptions directly relevant to your work qualify under HMRC rules.
• Keep a log of all interpreting assignments — date, client, duration, fee — as HMRC may require evidence of the business nature of each engagement.

Frequently Asked Questions

How do I declare income from overseas clients?

Convert all overseas income to sterling using HMRC's approved exchange rate on the date of payment. Declare the sterling equivalent on your Self Assessment return. Double taxation agreements may reduce withholding tax in certain countries.

Are CAT tool subscriptions (Trados, MemoQ) deductible?

Yes. Computer-Assisted Translation tools are professional software subscriptions used exclusively for your translation work — they are fully deductible as a business expense.

Is CIoL or ITI membership deductible?

Yes. Membership of the Chartered Institute of Linguists (CIoL) or the Institute of Translation and Interpreting (ITI) is a recognised professional body subscription and is fully deductible.

Does VAT apply when I provide translation services to overseas businesses?

When you provide translation services to a business customer outside the UK, the place of supply is where the customer belongs — not the UK. This means your services are outside the scope of UK VAT and you do not charge VAT. However, you still need to monitor your UK-customer turnover for the VAT registration threshold (£90,000).
