Hi,
There is a requirement to register for VAT if you are makung taxable supplies in the UK which are above the threshold of £85k. To determine your turnover you need to determine whether you are actually making taxable supplies in the UK.
If you are supplying services then it will depend who and where your customer is.
If your customer is an intermediary and they are based in the UK then this will be a taxable supply to the intermediary.
If your customer is the intermediary and they are based overseas then the supply will be Ouside The Scope Of UK VAT and hence no requirement to register for VAT.
Please see the guidance below:
The place of supply rules for services
Working out whether you need to register
You would only need to apply for an Exemption to registration if you are making zero rated supplies.
If you are making supplies which are Outside the Scope of VAT thern there is no requirement to apply for this.
Thank you.
