I only know the USA for sure. I can say this it was a fundemental thing for the USA when it was founded. In the England at the time the UK seperated debtor prisons were common, and as yous ay not paying taxes could get you in prison, as could not paying other debts.
In the USA we established early on debtors prison was a human rights violation, so you can never be jailed in the USA for not paying something you owe, even taxes. That said I am not sure if the UK still employees the older unjust laws of a debtors prison or if they have gotten some common sense and improved their approach.
