Around 600 self-employed businesses on the Island will be asked to fill out a survey on VAT.
It'll ask for information on either the irrecoverable VAT incurred by their business or business expenditure.
It's part of the wider Business VAT Survey, with Trust and Corporate Service Providers also set to be sent one soon.
Responses are compulsory, with the data collected used to work out the share of VAT, customers and other duties that the Island gets from the UK.
