I am not a US citizen and do not have any business in the US. I had problem filling the tax form. I mistakenly accepted to pay 30% to the US government per sale of my books. This is being deducted from the sales of my books. I want to correct this error because I am not a US citizen nor reside in the US.
How can I correct this tax error in my account?
It all depends on whether the U.S. and your country have a joint tax treaty. If they DO have a treaty, then the 30% at least gets lowered and often goes to zero. And if they DO have a treaty, then the ID number you should use in the Tax Interview is your own tax ID, the one you use in your own country when dealing with tax issues. In the UK, for example, those authors use their National Insurance Number.
If there is no treaty, then you're stuck with the 30% withholding. Theoretically you should be able to recover most or all of that after the end of the year by filing a 1040-NR return with the IRS. HOWEVER, most authors who are in your shoes find the process too much to bother with. Also, if you do get your money back from the IRS, it would be in the form of a U.S. check that you would then need to deposit or cash, somehow, in your country (and which likely would evoke a stiff bank charge).
It's your country, mate, not your citizenship. If you're from a country like the U.K. you'll have 0% withheld because we have a tax treaty with the U.S. Other countries have tax treaties specifying different amounts. If your country doesn't have a tax treaty, you're slammed with 30% and that's the way it is.
Nice find. Wonder why I didn't get that when I tried to search (I got a long-winded list of all international treaties, rather than a list of countries). Ah well. I bookmarked the list for future reference.
