Form 1040 is a U.S. federal tax return, not an Australian income tax form. This guide is for Australian-based readers who have U.S. filing obligations, including business owners and individuals with U.S. pass-through income.
The trail runs in three steps. Schedule C, Schedule K-1 and business records supply the income. Form 8995 or 8995-A calculates the deduction. Form 1040 reports the result.
Key Takeaways
- On the final 2025 Form 1040, the QBI deduction sits on line 13a.
- Form 8995 or 8995-A does the calculation, not Form 1040.
- Schedule C profit and some K-1 items feed QBI, but not every item qualifies.
- Check tax year, filing status, SSTB status, income limits, wage/property limits and loss carryforwards.
Where Does the QBI Deduction Appear on Form 1040?
Line number on Form 1040
The final 2025 Form 1040 shows "Qualified business income deduction from Form 8995 or Form 8995-A" on line 13a. Forms 1040-SR and 1040-NR use the same line.
Draft 2026 forms place it on line 13b. Drafts aren't for filing, so confirm the final version before you rely on that number.
The figure on Form 1040 is the allowable deduction. It isn't 20% of gross receipts or your Schedule C profit. It reduces taxable income (the subtraction that produces line 15), not adjusted gross income, which is reported at line 11a. It is also separate from self-employment tax and itemised deductions.
Role of Form 8995 and Form 8995-A
Both forms calculate the deduction before it moves to Form 1040. On the 2025 forms, the final deduction is line 15 of Form 8995 and line 39 of Form 8995-A.
Form 8995 is the short form. You can use it only if all three apply:
- You have QBI, qualified REIT dividends or qualified PTP income.
- Taxable income before the QBI deduction is at or below the threshold.
- You aren't a patron of a specified agricultural or horticultural cooperative.
Otherwise, use Form 8995-A. An SSTB can still use the short form below the threshold. Aggregation doesn't automatically bar it either, though you must attach an aggregation schedule.
How to find the amount on a completed return
- Locate Form 8995 or 8995-A in the return package.
- Note the final deduction on line 15 (Form 8995) or line 39 (Form 8995-A).
- Confirm that same amount appears on the QBI line of Form 1040.
The flow is simple. Schedule C or K-1 data goes into the QBI calculation, the allowable deduction is determined, and that amount carries to Form 1040.
How QBI Information Flows from Business Forms to Form 1040
Schedule C income
A sole proprietor's or single-member LLC's QBI starts with Schedule C net profit or loss, not gross receipts. Yet the Form 8995 instructions warn that Schedule C profit isn't automatically QBI. You must identify qualified items first.
Owner-level adjustments also reduce QBI:
- Deductible part of self-employment tax
- Self-employed health insurance
- Qualified retirement plan contributions
So can Schedule C filers claim QBI? Yes. You compute the deduction on the QBI form and report it on Form 1040, never as a Schedule C expense.
Schedule K-1 income
Partnership, S corporation and some LLC owners get QBI information on Schedule K-1 and an attached statement. Not every K-1 amount is QBI.
- Partnerships (Form 1065) use box 20, code Z.
- S corporations (Form 1120-S) use box 17, code V.
The statement reports qualified income items, W-2 wages, unadjusted basis immediately after acquisition (UBIA) of qualified property, and SSTB status. These feed your own Form 8995 or 8995-A. The K-1 supplies inputs, not a ready-made deduction.
Other inputs
Some items sit outside ordinary business income:
- Qualified REIT dividends, generally on Form 1099-DIV, box 5
- Qualified publicly traded partnership (PTP) income
- Prior-year loss carryforwards
REIT/PTP items form a separate component of the deduction. A negative ordinary QBI result doesn't necessarily wipe out a positive REIT/PTP component, and each type of loss carries forward in its own bucket.
Final reconciliation
You combine eligible income, apply the limits, and compare the result with the taxable-income cap before entering the amount. Before filing, confirm that:
- The Form 1040 line matches the final line of Form 8995 or 8995-A.
- Schedule C figures tie to the QBI inputs.
- K-1 statements agree with what you entered.
Who Is Eligible for the QBI Deduction and What Can Reduce It?
Business structures and qualifying income
Owners of sole proprietorships, partnerships and S corporations may qualify, along with certain trusts and estates, according to the IRS overview. C corporation income and employee wages don't qualify.
QBI must connect to a U.S. trade or business. This matters for Australian residents and nonresident aliens filing Form 1040-NR, where income must be effectively connected with a U.S. business. Common exclusions:
- Capital gains and losses
- Certain dividends and interest not tied to the business
- S corporation reasonable compensation
- Guaranteed payments and partnership payments for services
SSTBs and limits
Specified service trades or businesses (SSTBs) include health, law, accounting, consulting, financial services, brokerage, investment management and athletics.
Below the taxable-income threshold, an SSTB can still qualify. In the phase-in range, only a percentage of SSTB income counts. Above the upper endpoint, SSTB income no longer qualifies.
Higher earners also face a wage and property limit: the greater of 50% of W-2 wages, or 25% of W-2 wages plus 2.5% of UBIA (unadjusted basis immediately after acquisition). Separately, the deduction can't exceed 20% of taxable income minus net capital gain.
What changed for 2026
Public Law 119-21 made the deduction permanent for tax years starting after 2025. Taxable income thresholds (before the QBI deduction) are:
| Filing status | 2026 threshold | 2026 upper endpoint |
|---|---|---|
| Married filing jointly | $403,500 | $553,500 |
| Married filing separately | $201,775 | $276,875 |
| All other returns | $201,750 | $276,750 |
The phase-in range widens to $75,000 (non-joint) and $150,000 (joint). There is also a minimum: the greater of the computed deduction or $400, if active QBI totals at least $1,000. Active means material participation.
Don't treat 20% as guaranteed. Income level, W-2 wages, property (UBIA), losses and business type can all reduce the final amount.
Which Supporting Forms and Documents Should You Check?
Choosing between the forms
Use Form 8995 only if you meet the three conditions above. Otherwise, use Form 8995-A. Read the instructions for your tax year, because thresholds and line numbers change. The IRS also corrected its taxable-income instructions for both forms, so use current versions.
Documents to gather
- Schedule C and Schedule K-1, with supplemental statements
- Form 1099-DIV for qualified REIT dividends
- Prior-year QBI forms and loss-tracking worksheets
- Payroll and W-2 wage records
- Qualified-property records (UBIA uses basis on the placed-in-service date)
- Aggregation schedules, if you aggregate businesses
Also note your filing status, taxable income before the deduction, net capital gain and any SSTB.
When to get professional help
Consider professional help if any of these apply:
- Multiple pass-through businesses
- K-1 supplemental data or an SSTB
- Loss carryforwards, aggregation, or cooperative income
- A mismatch between Form 8995/8995-A and Form 1040

Common Mistakes When Looking for the QBI Deduction on Form 1040
Confusing QBI with the deduction
QBI is the income measure. The deduction is the allowable amount on Form 1040. Don't enter gross receipts, total K-1 income or a flat 20% without applying the limits.
Using the wrong form, year or line
Use the right edition of Form 1040, 1040-SR or 1040-NR. Line 13a (2025) and line 13b (2026 draft) differ, and a June 2026 draft Form 8995 instruction still points to 13a.
Tax software may label it "qualified business income deduction," so reconcile its output with the official forms.
A TIGTA report on 2019 paper returns found 5,193 returns with $45.3 million in QBI deductions processed incorrectly, partly because Forms 8995 or 8995-A were missing.
Ignoring carryforwards and special limits
Frequent errors include:
- Missed QBI loss carryforwards
- Omitted K-1 supplemental information
- Wrong SSTB treatment
- Overlooked wage/property limits
- No taxable-income cap applied
Pre-filing checklist:
- Verify eligibility
- Confirm source income
- Use the correct QBI form
- Match the final amount to Form 1040
- Keep your records
Frequently Asked Questions
Where to enter QBI deduction on 1040?
The final amount transfers from Form 8995 or 8995-A to the qualified business income deduction line, line 13a on the 2025 form. Confirm the line on your year's form.
Can I take QBI on Schedule C?
Eligible Schedule C net profit can generate QBI. The deduction is calculated on Form 8995 or 8995-A and reported on Form 1040, not as a Schedule C expense.
Does K-1 income qualify for QBI?
Some partnership, S corporation and LLC K-1 income qualifies. Review the K-1 and its supplemental statement, because not every item is QBI.
What is the QBI deduction limit for 2026?
The deduction is generally 20%, capped by taxable income minus net capital gain, and subject to SSTB, wage and property rules. Thresholds start at $403,500 (joint) and $201,750 (others), with a $400 minimum for active QBI.
Who is eligible for the QBI deduction?
Owners of qualifying pass-through businesses, plus certain trusts and estates. C corporation income and employee wages don't count, and SSTB rules and taxable income can reduce the amount.
What is qualified business income?
QBI is the net income, gain, deduction and loss from a qualifying U.S. trade or business. Capital gains, unrelated dividends, wages and guaranteed payments are excluded.
