Final answer:
The true statement regarding PTINs is that tax preparers must enter their PTIN on the tax returns they prepare for compensation. PTINs are not issued on a semi-annual basis, and they are specific to tax preparers, not taxpayers who are victims of identity theft.
Step-by-step explanation:
The statement that is TRUE regarding preparer tax identification numbers (PTINs) is: 4. The preparer must enter their PTIN on the tax return in the space provided. PTINs are mandatory identifiers that all paid tax preparers must use on U.S. federal tax returns or claims for refund submitted to the Internal Revenue Service (IRS). A PTIN is required for each tax preparer annually, not semi-annually. It is incorrect to say that tax preparers can legally prepare tax returns for compensation without a PTIN. Also, PTINs are for tax preparers and not provided to taxpayers as a direct consequence of identity theft, though the IRS has other mechanisms to assist identity theft victims.
