Answer:
$60,000
Step-by-step explanation:
Since Peter's taxable income before the QBI is $285,000, he can claim the maximum QBI deduction. The current phase out starts at $326,600 for married filing jointly or $163,300 for single filers.
Maximum QBI deduction = 20% x qualified business income (QBI) = 20% x $300,000 = $60,000
