I appreciated this description of the difference between American and Swedish tax preparation by some who files both:
Our US federal and state forms tax forms were more than 30
pages long last year, downloaded completely blank. During
the two weeks we'll spend in Wisconsin this summer, our main
job will be to get our taxes done.
I'll wade through stacks of bank and credit card records
line by line, documenting all professional income beyond our
wages and scanning for every possible business or charitable
deduction. Once this is done, we — like the majority of US
taxpayers — will hire a tax professional who charges us $500
to review and co-sign our work.
Tax-preparation services cost American taxpayers more than
$32 billion per year. My wife, Betty, and I each have a PhD,
but that's not enough to understand IRS instructions.
Finally, with a great sigh of relief, our marriage still
intact, we'll sign the forms and send them to the IRS.
Of course, despite our great efforts, we don't know whether
the IRS is going to be happy or not. We might get audited
and have to dig up all this stuff again, because the
government has three years to check and revise our returns.
In Sweden, the four-page tax form comes in the mail already
filled out. On a Saturday morning, Betty and I take our
coffee to the couch and review the forms. Seeing they look
reasonable, as they always do, we "sign" with a text from
our phones. In 15 minutes we are done. We don't have to hire
a tax consultant, and we avoid fights about whether a print
cartridge bought at the drugstore is a business expense or
not.
