10 facts about the pass-through deduction for qualified business income

Are you eligible to take the deduction for qualified business income (QBI)? Here are 10 facts about this valuable tax break, referred to as the pass-through deduction, QBI deduction or Section 199A deduction. 

  1. It’s available to owners of sole proprietorships, single member limited liability companies (LLCs), partnerships and S corporations. It may also be claimed by trusts and estates.
  2. The deduction is intended to reduce the tax rate on QBI to a rate that’s closer to the corporate tax rate.
  3. It’s taken “below the line.” That means it reduces your taxable income but not your adjusted gross income. But it’s available regardless of whether you itemize deductions or take the standard deduction.
  4. The deduction has two components: 20% of QBI from a domestic business operated as a sole proprietorship or through a partnership, S corporation, trust or estate; and 20% of the taxpayer’s combined qualified real estate investment trust (REIT) dividends and qualified publicly traded partnership income.
  5. QBI is the net amount of a taxpayer’s qualified items of income, gain, deduction and loss relating to any qualified trade or business. Items of income, gain, deduction and loss are qualified to the extent they’re effectively connected with the conduct of a trade or business in the U.S. and included in computing taxable income.
  6. QBI doesn’t necessarily equal the net profit or loss from a business, even if it’s a qualified trade or business. In addition to the profit or loss from Schedule C, QBI must be adjusted by certain other gain or deduction items related to the business.
  7. A qualified trade or business is any trade or business other than a specified service trade or business (SSTB). But an SSTB is treated as a qualified trade or business for taxpayers whose taxable income is under a threshold amount.
  8. SSTBs include health, law, accounting, actuarial science, certain performing arts, consulting, athletics, financial services, brokerage services, investment, trading, dealing securities and any trade or business where the principal asset is the reputation or skill of its employees or owners.
  9. There are limits based on W-2 wages. Inflation-adjusted threshold amounts also apply for purposes of applying the SSTB rules. For tax years beginning in 2021, the threshold amounts are $164,900 for singles and heads of household; $164,925 for married filing separately; and $329,800 for married filing jointly. The limits phase in over a $50,000 range ($100,000 for a joint return). This means that the deduction reduces ratably, so that by the time you reach the top of the range ($214,900 for singles and heads of household; $214,925 for married filing separately; and $429,800 for married filing jointly) the deduction is zero for income from an SSTB.
  10. For businesses conducted as a partnership or S corporation, the pass-through deduction is calculated at the partner or shareholder level.

As you can see, this substantial deduction is complex, especially if your taxable income exceeds the thresholds discussed above. Other rules apply. Contact us if you have questions about your situation.

Close-up on the new QBI deduction’s wage limit

The Tax Cuts and Jobs Act (TCJA) provides a valuable new tax break to noncorporate owners of pass-through entities: a deduction for a portion of qualified business income (QBI). The deduction generally applies to income from sole proprietorships, partnerships, S corporations and, typically, limited liability companies (LLCs). It can equal as much as 20% of QBI. But once taxable income exceeds $315,000 for married couples filing jointly or $157,500 for other filers, a wage limit begins to phase in.

Full vs. partial phase-in

When the wage limit is fully phased in, at $415,000 for joint filers and $207,500 for other filers, the QBI deduction generally can’t exceed the greater of the owner’s share of:

  • 50% of the amount of W-2 wages paid to employees during the tax year, or
  • The sum of 25% of W-2 wages plus 2.5% of the cost of qualified business property (QBP).

When the wage limit applies but isn’t yet fully phased in, the amount of the limit is reduced and the final deduction is calculated as follows:

  1. The difference between taxable income and the applicable threshold is divided by $100,000 for joint filers or $50,000 for other filers.
  2. The resulting percentage is multiplied by the difference between the gross deduction and the fully wage-limited deduction.
  3. The result is subtracted from the gross deduction to determine the final deduction.

Some examples

Let’s say Chris and Leslie have taxable income of $600,000. This includes $300,000 of QBI from Chris’s pass-through business, which pays $100,000 in wages and has $200,000 of QBP. The gross deduction would be $60,000 (20% of $300,000), but the wage limit applies in full because the married couple’s taxable income exceeds the $415,000 top of the phase-in range for joint filers. Computing the deduction is fairly straightforward in this situation.

The first option for the wage limit calculation is $50,000 (50% of $100,000). The second option is $30,000 (25% of $100,000 + 2.5% of $200,000). So the wage limit — and the deduction — is $50,000.

What if Chris and Leslie’s taxable income falls within the phase-in range? The calculation is a bit more complicated. Let’s say their taxable income is $400,000. The full wage limit is still $50,000, but only 85% of the full limit applies:

($400,000 taxable income – $315,000 threshold)/$100,000 = 85%

To calculate the amount of their deduction, the couple must first calculate 85% of the difference between the gross deduction of $60,000 and the fully wage-limited deduction of $50,000:

($60,000 – $50,000) × 85% = $8,500

That amount is subtracted from the $60,000 gross deduction for a final deduction of $51,500.

That’s not all

Be aware that another restriction may apply: For income from “specified service businesses,” the QBI deduction is reduced if an owner’s taxable income falls within the applicable income range and eliminated if income exceeds it.
