Some who know little of LETS consider it an opportunity for benefit fraud and tax evasion. Nothing could be further from the truth, because it is in the nature of a LETS system that the income, expenditure and current balances of all members are made available to all others. There is nothing to prevent tax or benefits officials joining privately and making use of this information in their official capacity; nor would any LETS administrators be likely to refuse cooperation in response to a legitimate official enquiry. I can only comment on the position in the UK as I must claim ignorance of the tax and benefit laws elsewhere, but from what little I have gathered, I understand that similar principles apply throughout the English speaking world. According to Michael Linton, the originator of the first LETS system in British Columbia, Canada, the current tax and benefit laws (presumably in Canada ?) are as appropriate to LETS money systems as the 19th century transport laws were to jet travel.
