Current US tax law requires much information the IRS doesn't have, including taxpayer marital status (are you living in the same household with your spouse?), number and age of dependents (are they in school?), itemized deductions, etc. The IRS does attempt to prepare returns for non-filers, they have very low accuracy. Countries that prepare income tax returns for the taxpayer have tax laws designed to be compatible with that mode of filing.
