$110,000

D.

$126,000

How to approach this question

Calculate Option A: 90% of Current ($140,000) = $126,000.<br/>4. Calculate Option B: 110% of Prior ($100,000) = $110,000.<br/>5. Select the lesser of the two options.

Full Answer

The taxpayer is a high-income taxpayer (AGI > $150,000). The safe harbor is the lesser of:<br/>1. 90% of current year tax: 0.90 * $140,000 = $126,000.<br/>2. 110% of prior year tax: 1.10 * $100,000 = $110,000.<br/>The minimum required is $110,000.
