Also in the area where I live, most home trade jobs are done with as much cash as possible to avoid taxes.
The pay cash tax savings is greater then any bank financing.
When you pay 50% income taxes you can see that the incentive to work cash is much much greater then formal financing.
If a car repair was going to cost $1000, the tradesperson keeps $500 after tax. He's better off to offer you $750 cash. Take $500 now (he's paid up).
Then if he still collects the $250 cash that's pure bonus.
I didn't even factor in the 20% sales taxes on the work the buyer would have to pay.
All I can say is don't try to expand to a newly third world country like Canada. I just can't see it working here.
So a (filing single) contractor making 160,000 in California would pay more like $60k in total taxes (which is still 37.5% effective).
But given the number of UK folks for this topic, the “Social Security” and FICA amount (~15%, so nearly half of “tax”) is effectively similar to National Insurance.
Most trades in Canada are max tax rate, because the max tax rate kicks in at extremely low levels compared to USA.
Someone earning 60K USD in Canada (~75K CAD) would have a marginal income tax rate ranging from 27% to 38%, depending on their province. If they're a contractor, they'd have access to a bunch of deductions against their expenses. They could further use an RRSP to shelter their income, or at least defer taxes to future years with lower income, thus driving their average tax rate down.
