Question 1

What is the Section 199A QBI deduction?

Accepted Answer

Section 199A allows eligible self-employed and pass-through business owners to deduct up to 20% of qualified business income (QBI) from their taxable income. This deduction was created under the Tax Cuts and Jobs Act and is available through 2025.

Question 2

What is a Specified Service Trade or Business (SSTB)?

Accepted Answer

SSTBs include health, law, accounting, actuarial science, performing arts, consulting, athletics, financial services, and any trade where the principal asset is the reputation/skill of employees. SSTBs face full phaseout of QBI deduction above income thresholds ($170,050 single, $340,100 married for 2024).

Question 3

What are the income thresholds for QBI deduction limits?

Accepted Answer

For 2024: Phaseout begins at $170,050 (single) or $340,100 (married filing jointly). Full limitation applies above $220,050 (single) or $440,100 (married). Below threshold: full 20% deduction. Above: limited by 50% of W-2 wages or 25% wages + 2.5% qualified property.

Question 4

How can I maximize my QBI deduction above thresholds?

Accepted Answer

For non-SSTB businesses above threshold: hire W-2 employees (wages increase deduction limit), invest in qualified property (equipment, buildings), or aggregate multiple businesses. SSTBs cannot exceed threshold for full deduction, so consider income timing strategies.

Question 5

Does the QBI deduction apply to all business income?

Accepted Answer

No. QBI excludes: capital gains/losses, dividends, interest income, income earned outside the US, reasonable compensation paid to the taxpayer as wages, and guaranteed payments to partners. Only qualified business income from qualified trades or businesses qualifies.
