In the UK: Taxes are complicated but mostly solved. Either your employers deduct taxes before you get your money or you are self-employed and pay an accountant to sort it out; and people you buy things from add taxes before you buy stuff. If you are rich you get an accountant and practice various forms of avoidance (legal, but those loopholes may close soon, and of dubious ethicality) to evasion (not legal).
Missing from the above description are people involved in barter economies. There are several barter economy systems in the UK. The UK tax collectors (HM Revenue and Customs) are clear: barter trades can be taxable.
Suggestion: Find an accountant that would like to work as part of a co-operative. The collective either has one big joint account (like a business) or lots of individual accounts - either way good accounting will legally minimise tax burden and help with other stuff.
Awesome, thanks for the suggestion. Do you suppose the accounting could also be automated, with help from an accountant, as part of the system that facilitates exchanges? My current thinking is to create a system that can be used by anyone, not just those within a single collective.
