CPA · Question 04 · Area I: Individual Compliance and Planning

An individual taxpayer had an AGI of $160,000 in Year 1 and a tax liability of $30,000. In Year 2, the taxpayer expects an AGI of $200,000 and a tax liability of $45,000. To avoid the underpayment penalty for Year 2 without paying more than necessary during the year, what is the minimum required annual estimated tax payment?

Answer options:

A.

$30,000 (100% of prior year tax)

B.

$40,500 (90% of current year tax)

C.

$33,000 (110% of prior year tax)

D.

$45,000 (100% of current year tax)

How to approach this question

Check the AGI threshold ($150,000). Since AGI > $150k, the safe harbor is the lesser of 90% of current year tax or 110% of prior year tax.

Full Answer

C.$33,000 (110% of prior year tax)✓ Correct
IRC §6654(d)(1)(C) modifies the safe harbor for individuals with AGI over $150,000 in the preceding year. They must pay the lesser of 90% of the current year's tax ($45,000 * 0.9 = $40,500) or 110% of the prior year's tax ($30,000 * 1.1 = $33,000). $33,000 is the minimum.

Common mistakes

Using 100% of prior year tax despite high income; calculating 110% of current year tax; failing to compare the two safe harbor options.
