>All I got to do is look over what they have filled out and correct it if I think anything is wrong. Its pretty much the same in the USA if you just have income from a standard job. You send them your W2 form with the last year's salary and make sure everything is right. If you're self-employed, earned income some other way (capital gains, etc), or live in a state with additional state income tax, you have to fill out some more forms. Then it gets a bit complicated calculating deductions. Which means you have to put in some effort if you want to lower your effective tax rate. There's deductions for everything under the sun since the tax code is very complex. You get some money back if you paid interest on student loans, have kids, bought a house, spend money on office supplies, gave to charity, etc. Some people spend a few hundred on a tax advisor to do it for them and still come out ahead. Many people simply don't bother and let the money go. The IRS only comes after you if you underpay, not overpay.
