QBI Deduction Explained: Income Limits & How to Qualify

Qualified business income deduction (QBI) is one of the biggest self-employed tax deductions that business owners and freelancers can leverage. It allows them to deduct a large portion of their business earnings before calculating taxes, thus reducing the final tax bill by a potentially considerable amount.

In this article, we’ll explain exactly what the qualified business income deduction is and who qualifies for it. Following that, we’ll see what counts as QBI before showing you how to calculate the deduction. We’ll then go through QBI income deduction limits and explain how you can claim them before discussing some of the common mistakes that you need to avoid.

What Is the Qualified Business Income Deduction?

The qualified business income deduction (also referred to as the Section 199A deduction) allows eligible taxpayers to deduct up to 20% of the income they earned from their trade or business.

QBI was introduced by the Tax Cuts and Jobs Act (TCJA) of 2017. Its primary goal is to provide a tax benefit to pass-through entities (typically small and medium-sized businesses) that is comparable to significant reductions in corporate tax implemented with the TCJA.

It’s important to know that the qualified business income tax deduction is classified as a below-the-line deduction. This means it doesn’t lower your AGI (unlike most other traditional business expenses), allowing you to claim it whether you itemize your deductions or take the standard deduction.

On the other hand, it requires meticulous income tracking and calculations, since it’s based on your net income. It’s also subject to multiple limitations (e.g., business type restrictions or taxable income thresholds) and does not apply to all income.

Who Qualifies for the QBI Deduction?

QBI deductions can provide significant benefits to businesses and professionals, but they need to meet strict IRS criteria related to their business structure, income level, and type of activity.

#1. Eligible Business Types

The qualified business income deductions are primarily reserved for pass-through business types. This includes:

• Sole proprietorships
• Single-member LLCs
• Multi-member LLCs
• Partnerships
• S corporations
• Certain estates and trusts

In these business structures, income passes to the owner and is not taxed at the corporate level. Instead, it is taxed at individual income tax rates when owners file personal tax returns; this allows them to claim qualified business income deductions.

On the other hand, C corporation income does not qualify for the QBI deduction since it’s taxed at the corporate level.

#2. Income Requirements

Whether you’re eligible for qualified business income deductions depends on your total taxable income from all sources, not just your business.

If this income falls below a certain threshold, you’re eligible for the full 20% deduction. These thresholds are based on your filing status, and their values are subject to change. For the tax year 2025 (filed in 2026), the maximum threshold for full QBI deduction is:

• $394,600 for married filing jointly
• $197,300 for all other returns

If your income goes above that, QBI deductions get phased out. They can be partially or fully reduced based on the W-2 wages that your business pays or the unadjusted basis of qualified property that it holds.

#3. Specified Service Trade or Business

Specified service trade or business (SSTB) refers to a profession that primarily revolves around the skill or reputation of the owner or employees. Some examples include fields of law, healthcare, consulting, accounting, and financial services.

Furthermore, SSTBs are subject to stricter rules when it comes to qualified business income deductions.

If you operate as one, your QBI deductions also start getting phased out after your income reaches $394,600 or $197,000. However, once your income reaches $494,600 for married filing jointly or $247,300 for all other returns, your QBI deduction is reduced to zero.

What Counts as Qualified Business Income?

Qualified business income refers to the net amount of income, gain, deduction, and loss from a qualified business or trade. It must be related to federally recognized business or trade affairs physically conducted in the United States.

In simple terms, it’s your business profit after expenses, but before some exclusions. This means that you reduce your gross revenue by standard business expenses, including contributions to qualified retirement plans, self-employed health insurance premiums, and deductible portions of self-employment tax.

Let’s start with what’s included in a qualified business income:

• Net business income reported on Schedule C, E, or F
• Income from partnerships and S corporations
• Certain rental income, if it qualifies as a business

However, the IRS also excludes several types of income from QBI, such as:

• Reasonable compensation you pay yourself as an S corporation owner
• Guaranteed payments you receive in a partnership
• Capital gains or losses
• Income generated from foreign businesses
• Dividends and interest not related to your business
• W-2 wages that you earn as an employee

For example, if you’re a freelancer who made $100,000 in revenue and claimed $30,000 in business expenses as 1099 tax deductions, your qualified business income will be $70,000. You’ll then use the $70,000 figure to determine your freelancer tax deductions.

Keep in mind that QBI is determined per business. This means that you need to calculate income and deductions for each one separately before combining them under aggregation rules. It also allows you to treat the aggregate as a single trade or business for deduction purposes.

Besides that, you should also be aware that losses from one business may offset income from another, thus reducing your overall QBI deduction.

How Do You Calculate the QBI Deduction?

You calculate the QBI deduction by taking up to 20% of your qualified business income, subject to income thresholds and additional limitations. If your taxable income is below IRS limits, the calculation is straightforward; otherwise, wage and property limits apply.

The basic formula goes as follows:

• QBI Deduction = 0.2 * Qualified Business Income (QBI)

Let’s see that in an example of a freelance software developer who is operating as a single-member LLC and has earned $90,000 net business profit in a single tax year. Since their taxable income is below the threshold, the calculations go like this:

• QBI = $90,000
• Deduction = 0.2 * $90,000 = $18,000

As a result, the freelance software developer can deduct $18,000 from their taxable income before their final income tax bracket is applied.

However, if the taxpayer’s income exceeds the threshold, additional limitations apply. These limitations take into account the taxpayer’s W-2 wages and the value of qualified property. All of this requires precise calculations (and often professional tax assistance) to ensure compliance, so let’s find out what the limits are.

QBI Deduction Income Limits

As previously mentioned, there are certain income limits associated with QBI deductions that dictate whether you’re eligible for them and in what amounts. These limits are based on annual income and are set by the IRS.

For example, the QBI income limits for the tax year 2025 are as follows:

• $394,600 for married filing jointly
• $197,300 for single filers and everyone else

Up until these limits, you can typically claim the full 20% qualified business income deduction.

However, if your income exceeds these thresholds, it enters the phaseout range, where it can be reduced to the greater of the following two:

• 50% of W-2 wages paid by the qualified trade or business
• 25% of W-2 wages plus 2.5% of the UBIA (unadjusted basis immediately after acquisition) of qualified property

Due to the stricter rules for SSTBs, the owners of these businesses lose the QBI deduction entirely once their annual income surpasses the upper ceiling, which is:

• $494,600 for married filing jointly
• $247,300 for single filers and everyone else

Since these thresholds change annually, it’s essential to check the current limits at the IRS website when filing.

How to Claim the QBI Deduction

To claim the QBI deduction, you need to accurately complete your annual personal income tax return (Form 1040) and, in most cases, attach one of the two forms issued by the IRS:

• Form 8995, Qualified Business Income Deduction Simplified Computation
• Form 8995-A, Qualified Business Income Deduction

Form 8995 is for taxpayers whose income falls below the phaseout threshold and is generally easier to fill out than Form 8995-A, as the situation is straightforward. You typically list your business, calculate 20% of your QBI, check it against the taxable income limitation, and report the final deduction amount.

Meanwhile, Form 8995-A is for taxpayers whose income exceeds the phaseout threshold, or who are patrons in a specified agricultural or horticultural cooperative. This form is typically much more complex and challenging to fill out, and may require including one or more of the following schedules:

• Schedule A (Form 8995-A), Specified Service Trades or Businesses.
• Schedule B (Form 8995-A), Aggregation of Business Operations.
• Schedule C (Form 8995-A), Loss Netting and Carryforward
• Schedule D (Form 8995-A), Special Rules for Patrons of Agricultural or Horticultural Cooperatives.

The calculations usually require a consideration of various factors, like W-2 wage limitations, UBIA of qualified property, and phase-out restrictions specific to Specified Service Trades or Businesses (SSTBs).

The final figure from either of these forms will go into your Form 1040 to reduce your taxable income.

6 Common QBI Mistakes to Avoid

Various QBI mistakes can make you miss out on the full value of your qualified business income deduction or lead you to an IRS audit due to a miscalculation.

Here are the most common ones:

• Mixing up gross income with QBI. Many business owners use their gross revenue when applying the 20% calculation. However, the deduction only applies to net profit, after deducting all business expenses considered ordinary and necessary.
• Including ineligible income. Some taxpayers make the mistake of adding their W-2 wages or guaranteed payments to their qualified business income. Others include capital gains or dividends, which are also not a part of QBI. Doing this artificially inflates QBI and results in more deductions than can be claimed.
• Misclassifying an SSTB. The IRS has strict rules when it comes to SSTBs. Incorrectly classifying your business as a non-SSTB to avoid phase-out limitations can result in severe penalties.
• Not tracking multiple businesses separately. While multiple businesses can be aggregated (provided they meet the strict criteria established by the IRS), you must first evaluate them individually.
• Misapplying wage and property limits. Wage and property rules only apply if your annual income is above the established threshold. Some taxpayers apply them regardless (even if their income is below the limit), resulting in unnecessary administrative work and miscalculations.
• Skipping the required forms. Whether you use Form 8995 or 8995-A, you must attach it to your Form 1040. Filing your tax return without these forms will likely result in a rejection or an adjusted return.

Final Thoughts

The qualified business income deduction can be a great financial asset to your business that can reduce your overall tax burden by a significant amount. However, it’s important to be aware of the strict rules and limitations imposed by the IRS when determining your eligibility and performing the calculations.

Once you understand the nuances around QBI, SSTBs, income thresholds, and aggregation rules, you can apply that knowledge to achieve substantial tax savings. Keep in mind that it’s always better to hire a tax professional if you need guidance, as it can help you avoid miscalculations, underutilization of QBI deductions, or even IRS audits.

Qualified Business Income Deduction FAQs

#1. Why am I not getting the qualified business income deduction?

You may not get the qualified business income deduction if you’ve reached SSTB limitations or don’t have qualified business income (e.g., your business operated at a net loss). No deduction applies if your income is entirely from excluded W-2 wages or guaranteed payments, too.

#2. Can W-2 employees claim QBI?

No, W-2 employees can’t claim QBI. The deduction is reserved for individuals who generate income from pass-through businesses or self-employment (e.g., sole proprietors, LLC owners, partners in partnerships, S corporation owners).

#3. Do I qualify as a freelancer?

As a freelancer, you generally qualify for the QBI deduction. However, you must ensure that your income falls within the established threshold and that you conduct your business operations primarily in the United States before using the QBI deduction for your freelance tax.

#4. What if I have multiple businesses?

If you have multiple businesses categorized as pass-through entities, you must first calculate the QBI for each business separately. Then, you can combine them if they meet strict IRS aggregation rules. This allows you to view them as a single entity for deduction purposes.
