What the Pass-Through Deduction Is
The pass-through deduction is a federal tax provision that allows eligible taxpayers to subtract a portion of their qualified business income from their taxable income. Designed primarily for owners of pass-through entities, it lowers the overall tax burden without reducing the amount of business deductions or credits a taxpayer can otherwise claim. The deduction is available on both personal and joint returns, and it applies regardless of whether the taxpayer itemizes deductions.

Because pass-through entities do not pay federal income tax at the entity level, the deduction helps prevent double taxation. Instead of the business paying tax and then the owner paying tax again on the same income, the deduction reduces the owner's personal taxable income directly. The Internal Revenue Service has published guidance clarifying that the deduction applies to income from sole proprietorships, S corporations, partnerships, and certain trusts and estates.
Who Qualifies for the Deduction
Taxpayers must meet several conditions to claim the pass-through deduction. The individual must have qualified business income from a domestic pass-through entity, and the deduction is limited to 20% of the lesser of qualified business income or taxable income before the deduction. For taxpayers with taxable income above specified thresholds, additional limitations may apply based on the type of business and the amount of W-2 wages and qualified property involved.
The deduction is not available to individuals who are employees receiving a W-2 salary, nor is it available to corporations subject to corporate income tax. However, some trusts and estate beneficiaries can still qualify under certain conditions. The deduction phases in for taxpayers above the threshold income levels and phases out for those with very high incomes, which means eligibility depends on both the type of entity and the taxpayer's total income picture.
Income Limits and Phase-In Rules
The IRS established initial income thresholds above which the deduction begins to be limited. For single filers, the threshold starts at a specific dollar amount, and for married couples filing jointly, the threshold is roughly double that amount. These thresholds are adjusted periodically for inflation. When taxable income exceeds the threshold, the deduction may be restricted based on the greater of 50% of W-2 wages paid by the business or 25% of W-2 wages plus 2.5% of the unadjusted basis of qualified property.
Some service trades or businesses are subject to further limitations or complete exclusion once taxable income crosses a higher threshold. These typically include businesses involving the performance of services in the fields of health, law, accounting, actuarial science, performing arts, consulting, athletics, financial services, brokerage services, or any trade or business where the principal asset is the reputation or skill of one or more employees or owners. The rules for these specified service trades and businesses are stricter, and taxpayers in those fields should review their specific circumstances carefully.
How the Deduction Interacts With Business Structures
The structure of a business affects how the pass-through deduction is calculated and claimed. For sole proprietors, the deduction is claimed on Schedule C and flows through to the individual return. For S corporation shareholders, the deduction depends on the shareholder's pro-rata share of qualified business income, W-2 wages, and qualified property. For partnerships, the calculation follows each partner's distributive share, and the partnership generally does not claim the deduction itself.
| Business Structure | Where Deduction Is Claimed | Key Limiting Factors |
|---|---|---|
| Sole Proprietorship | Individual return (Form 1040) | Qualified business income, taxable income thresholds |
| S Corporation | Individual return (Form 1040) | Shareholder's share of W-2 wages, qualified property |
| Partnership | Partner's individual return | Distributive share of income, W-2 wages, qualified property |
| Trust or Estate | fiduciary return or beneficiary return | Trust income thresholds, beneficiary circumstances |
Qualified Business Income and Eligible Property
Qualified business income generally includes net income from a qualified trade or business, reduced by the deduction allowed for depreciation. It does not include capital gains or losses, dividends, or interest income. The deduction also depends on the taxpayer's basis in qualified property, which means the original cost of certain depreciable assets used in the business. Understanding what counts as qualified business income is essential for accurate calculation and compliance.
Taxpayers should keep thorough records of income, wages, and property basis. The deduction is not automatic, and claiming it incorrectly can lead to adjustments or penalties. The IRS provides worksheets and instructions, and many tax preparation software packages include dedicated sections for the pass-through deduction to help taxpayers determine their eligibility and amount correctly.
