The Tax Cuts and Jobs Act (TCJA), the massive tax reform law that took effect in 2018, established a new tax deduction for owners of pass-through businesses. Pass-through owners who qualify can deduct up to 20% of their net business income from their income taxes, reducing their effective income tax rate by 20%. This deduction began in 2018 and is scheduled to last through 2025—that is, it will end on January 1, 2026, unless Congress extends it.
This deduction can really add up. For example, if you have $100,000 in pass-through income, you could qualify to deduct $20,000, reducing your income taxes by a whopping $4,400 if you're in the 22% income tax bracket. Clearly, all small business owners need to understand this complex deduction.
Here are the requirements to take it.
You must have a pass-through business to qualify for this deduction. A "pass-through business" is any business that is owned and operated through a pass-through business entity, which includes any business that is:
For tax purposes, what distinguishes these types of businesses is that they pay no taxes themselves. Instead, the profits (or losses) from such businesses are passed through the business, and the owners pay tax on the money on their individual tax returns at their individual tax rates.
The vast majority of smaller businesses are pass-through entities. Indeed, over 86% of businesses without employees are sole proprietorships.
Regular "C" corporations don't qualify for this deduction. However, they do qualify for a low 21% corporate tax rate on all their income. Unlike the pass-through deduction, the 21% rate for C corporations is permanent under the TCJA.
Individuals who earn income through pass-through businesses may qualify to deduct from their income tax an amount equal to up to 20% of their "qualified business income" (QBI) from each pass-through business they own. (IRC Sec. 199A).
QBI is the net income (profit) your pass-through business earns during the year. You determine this by subtracting all your regular business deductions from your total business income. QBI includes rental income so long as your rental activity qualifies as a business (as most do). It also includes income from publicly traded partnerships, real estate investment trusts (REITs), and qualified cooperatives.
QBI doesn't include:
QBI is determined separately for each separate business you own. If you own multiple businesses that are not service businesses listed below, you have the option of combining them into one for the deduction, but only if at least two of the following requirements are satisfied:
If one or more of your separate businesses lose money, you deduct the loss from the QBI of your profitable businesses. If you have a qualified business loss—that is, your net QBI is zero or less—you get no pass-through deduction for the year. Any loss is carried forward to the next year and is deducted against your QBI for that year.
To determine your pass-through deduction, you must first figure your total taxable income for the year (not counting the pass-through deduction). This is your total taxable income from all sources (business, investment, and job income) minus deductions, including the standard deduction ($13,850 for singles; $27,700 for marrieds in 2023). You must have positive taxable income to take the pass-through deduction.
Moreover, the deduction can never exceed 20% of your taxable income.
How the pass-through deduction is calculated depends on whether your taxable income (QBI income plus other taxable income) exceeds an annual threshold that is adjusted for inflation each year. For 2023, the threshold is taxable income up to $364,200 if married filing jointly, or up to $182,100 if single. If your income is within this threshold, your pass-through deduction is equal to 20% of your qualified business income (QBI). This is the maximum possible pass-through deduction.
If your taxable income is within the thresholds, that's all there is to the pass-through deduction. You can stop reading.
If your taxable income exceeds the annual threshold ($364,200 if married filing jointly; $182,100 if single for 2023), calculating your deduction is much more complicated and depends on your total income and the type of work you do. First of all, you need to determine whether your business falls within one of the following service provider categories:
A final catchall category includes any business where the principal asset is the reputation or skill of one or more of its owners or employees. IRS regulations narrowly define this catch-all category to include only cases where a person:
Architecture and engineering services are expressly not included in the list of personal services.
Pass-through owners who provide personal services are not favored under the pass-through deduction. Indeed, they lose the deduction entirely at certain income levels. No such limitations apply to pass-through owners who don't provide personal services.
If your business isn't included in the list of service providers, how you calculate your deduction depends on how much your taxable income exceeds the annual taxable income threshold ($364,200 if married filing jointly; $182,100 if single for 2023).
If you're a non-service provider and your taxable income is $100,000 or more above the income threshold if married filing jointly, or $50,000 if single, your pass-through deduction is fully subject to a W-2 wage/business property limitation. So, if you're married filing jointly, this limitation applies if your taxable income is over $464,200 ($232,100 if you're single). Your maximum possible pass-through deduction is 20% of your QBI, just like at the lower income levels. However, when your income is this high your deduction is further limited to the greater of:
Thus, you get no deduction if you have neither employees nor depreciable property. This is intended to encourage pass-through owners to hire employees and/or buy property for their business.
The business property must be depreciable long-term property used in the production of income—for example, the real property or equipment used in the business (not inventory). The cost is its unadjusted basis—the original acquisition cost minus the cost of land, if any. The 2.5% deduction can be taken during the entire depreciation period for the property; however, it can be no shorter than ten years.
Many owners of pass-through businesses, especially landlords, have no employees. Thus, the 25% plus 2.5% deduction is of most benefit to them.
If your taxable income is less than $100,000 over the threshold if you're married filing jointly, or $50,000 if you're single, the W2 wages/property limitation is phased in. For 2023, this applies if your taxable income is $364,201 to $464,200 if married filing jointly or $182,101 to $232,100 if single. In this event, only part of your deduction is subject to the W2 wage/property limit and the rest is based on 20% of your QBI. The phase-in range is $100,000 for marrieds, and $50,000 for singles. At the top of the range ($429,800 for marrieds, $214,900 for singles), your entire deduction is subject to the W2 wages/business property limit. If you have no W2 wages or business property, you get no deduction.
To calculate the phase-in, first, determine what the amount of your deduction would be if the W2 wages/property limit didn't apply at all—this is 20% x your QBI. Next, calculate your deduction as if the W2 wages/property limit applied in full. Your phase-in amount is based on the difference between these two calculations multiplied by your phase-in percentage.
If your business involves providing personal services, and your taxable income is over the $364,200/$182,100 thresholds, your pass-through deduction is gradually phased out up to $464,200/$232,100 of QBI. At the top of the income range, you get no deduction at all. That is, if your total income is more than $464,200 if you're married, or $232,100 if you're single, you get no deduction. This was intended to prevent highly compensated employees who provide personal services—lawyers, for example—from having their employers reclassify them as independent contractors so they could benefit from the pass-through deduction. There is no such phase-out of the entire deduction for nonservice providers.
To calculate your deduction, you start by using the same formula as for non-service providers discussed above. Your maximum possible deduction is 20% of your QBI. However, your deduction may not exceed the greater of:
Thus, if you have no employees or depreciable business property, you get no deduction.
Next, you calculate the phase-out of the deduction. If you have employees or property, your deduction is phased-out by 1% for every $1,000 your income exceeds the $364,200 threshold. When your income reaches $464,200 you get no deduction. If you're single, your deduction is reduced by 2% for every $1,000 your income exceeds the $184,100 threshold and you get no deduction if your income reaches $232,100.
The pass-through deduction is a personal deduction you may take on your Form 1040 whether or not you itemize. It is not an "above the line" deduction on the first page of Form 1040 that reduces your adjusted gross income (AGI). Moreover, the deduction only reduces income taxes, not Social Security or Medicare taxes.
