That depends on your country in which you file taxes. For example, in Australia you can get your TFN from an account you set up in MyGov with the ATO, Australian Tax Office. In the US, you are wanting your ITIN, Tax payer Identification number. If you do not have one, you apply for one with the Social Security Administration.

In order to retrieve a lost ITIN (that is Individual Taxpayer Identification Number), you will need to call the IRS ITIN Hotline at 1-800-908-9982. You can answer a series of questions to verify your identity and the IRS will provide you the number.

no
fixya site does not do tax file numbers
contact the taxation office and ask them how you can get it
of course it is at the top of last year tax return/refund form

Your question is unclear. Can you be more specific please? Thank you. If you have lost your important tax document you need to check-in with the SSA(Social Security Administration) as soon as possible

No, you cant be sure about distribution of taxes, charges, wages etc

Its easy just type in the tax rate that you want, then hit the rate button. Afterwards leave tax+ pressed and you should see the tax % sign appear above the number you punched in, and THATS IT!!! Easy!!!
