Answer:
a. Need not be filed if the estimated tax, after subtracting withholding, can reasonably be expected to be more than $1,000.
Step-by-step explanation:
Mr. Levy's estimated tax is the tax payment method for his income that is not subject to withholding. This income includes the earnings he receives from self-employment, interest, dividends, rents, and alimony. In addition, if Mr. Levy does not choose to have taxes withheld from his other taxable income, he should also make estimated tax payments.
