New self-employed tax deductions you can claim in 2026

If you file a Schedule C, run an S Corporation, or operate as a sole proprietor, the One Big Beautiful Bill Act (Public Law 119-21, signed July 4, 2025) changed your tax picture more than any legislation in the past decade. It permanently extended the 20% qualified business income deduction, which was set to expire, restored full domestic R&D spending, locked in 100% bonus depreciation through 2030, and introduced a brand-new IRS Schedule 1-A. Self-employed taxpayers who understand these changes can reduce their taxable income significantly before the April 15, 2026, deadline. Those who miss them will overpay.

What the OBBB Act changed for self-employed filers

The One Big Beautiful Bill Act touched nearly every major area of self-employed taxation. Unlike wage earners who simply receive a W-2, self-employed individuals must navigate the intersection of business income, self-employment tax, qualified business income deductions, and equipment expenses, all of which were modified by the new law.

The most impactful changes affecting self-employed filers for the 2025 tax year include:

• Permanent QBI deduction at 20%: Section 70105 permanently extends the qualified business income deduction under Section 199A, which was set to expire after 2025. The deduction remains at 20% of qualified business income, with the phase-in threshold raised from $50,000 to $75,000 for single filers ($100,000 to $150,000 for joint filers). A new minimum deduction of $400 applies to active business owners with at least $1,000 in qualified business income.
• Immediate domestic R&D expensing: Section 70302 (new Section 174A) allows full immediate deduction of domestic research and experimental costs in the year incurred, effective for tax years beginning after December 31, 2024. Small businesses with average annual gross receipts of $31 million or less may retroactively elect this treatment for tax years beginning after December 31, 2021.
• 100% bonus depreciation extended: Section 70301 extends 100% bonus depreciation through December 31, 2030, for qualifying property acquired and placed in service after January 19, 2025. No phase-down applies until 2030.
• Excess business loss cap made permanent: Section 70601 permanently extends the Section 461(l) limitation on excess business losses for noncorporate taxpayers, capping net business losses you can deduct against non-business income at $305,000 for single filers ($610,000 for joint filers) for the 2025 tax year, with annual inflation adjustments.
• Schedule 1-A for new above-the-line deductions: A new IRS form introduced for 2026 filing covers the no-tax-on-tips deduction, no-tax-on-overtime deduction, car loan interest deduction, and the senior standard deduction add-on. Self-employed individuals in qualifying tip-receiving occupations may be eligible, though those in specified service trades or businesses under Section 199A are excluded from the tips deduction.

How the permanent QBI deduction saves self-employed filers

For most self-employed taxpayers, the permanent Section 199A qualified business income deduction is the most valuable provision in the OBBB Act. Without it, the 20% deduction would have expired after December 31, 2025, costing every S Corporation owner, sole proprietor, and Partnerships member tens of thousands of dollars annually in higher taxes starting in 2026.

Here is a straightforward calculation showing what permanence means for a self-employed consultant:

1. Net qualified business income: $120,000
2. QBI deduction at 20%: $24,000
3. Taxable income reduction: $24,000
4. Tax savings at 22% marginal rate: $5,280 annually
5. Tax savings at 24% marginal rate: $5,760 annually

The OBBB Act also raised the phase-in threshold for W-2 wage and property limitations to $75,000 (up from $50,000) for single filers. It introduced a new $400 minimum deduction for active business owners with at least $1,000 in qualified business income. Coordinating this deduction with a Traditional 401k contribution reduces adjusted gross income, which can increase your QBI deduction if your income sits near a threshold.

Immediate R&D expensing is back and retroactive

One of the most significant reversals in the OBBB Act affects businesses that conduct domestic research and development. Under prior law, domestic R&D costs had to be amortized over five years starting in 2022, a requirement that hurt cash flow for technology companies, software developers, and any small business investing in product development.

Section 70302 creates a new Section 174A, which restores the full immediate expense deduction for domestic research and experimental costs. The key rules are:

• Full deduction applies to domestic R&D expenses paid or incurred in tax years beginning after December 31, 2024
• Foreign R&D costs must still be amortized over 15 years
• Software development costs are explicitly deductible under Section 174A
• R&D deductions are reduced by any research tax credits claimed under Section 41 (no double benefit)

The retroactive election is the provision most likely to generate immediate refunds. Small businesses with average annual gross receipts of $31 million or less can elect to apply Section 174A retroactively to tax years beginning after December 31, 2021, meaning they can recover R&D deductions that were improperly amortized over the prior three years. If your business paid for domestic R&D between 2022 and 2024 and amortized those costs, filing an amended return could generate a meaningful refund. The AI-driven R&D tax credits strategy pairs directly with this provision for technology-focused businesses.

How 100% bonus depreciation changes equipment decisions

The extension of 100% bonus depreciation through December 31, 2030, removes the guesswork from equipment purchasing decisions for self-employed individuals and small business owners. Prior to this extension, bonus depreciation was scheduled to phase down further in 2026 and beyond. Now, any qualifying property acquired and placed in service after January 19, 2025, qualifies for a full first-year deduction.

The combined impact of bonus depreciation and the enhanced Section 179 expense limit (raised to $2.5 million under Section 70306) gives self-employed taxpayers and small business owners two powerful tools for capital investment in 2025 and beyond. The interaction works as follows:

1. Apply Depreciation and amortization elections first under Section 179 up to the $2.5 million limit
2. Apply 100% bonus depreciation to the remaining qualifying property
3. Coordinate with the QBI deduction, as depreciation deductions reduce net QBI and thus the 20% deduction amount

For a self-employed graphic designer, photographer, or consultant who purchases $45,000 in equipment and software in 2025, the full $45,000 is immediately deductible rather than being spread over 5 or 7 years under MACRS. At a 22% marginal rate, that is $9,900 in immediate tax savings versus approximately $1,400 in the first year under traditional straight-line depreciation.

Planning your equipment purchases before December 31, 2025, to qualify for bonus depreciation in the current tax year is one of the most accessible high-impact strategies available to self-employed filers this filing season.

The excess business loss cap now applies permanently

Section 70601 of the OBBB Act permanently extends the Section 461(l) excess business loss limitation for noncorporate taxpayers, a rule that directly affects sole proprietors, S Corporations shareholders, and Partnership members who report business losses. The rule caps the amount of net business losses you can use to offset non-business income in a single tax year.

For the 2025 tax year, the limits are:

• Single filers: $305,000 cap on excess business losses
• Married filing jointly: $610,000 cap on excess business losses
• Losses above these thresholds carry forward as net operating losses

This is particularly relevant for self-employed individuals who experienced a business downturn, made large equipment purchases that created a paper loss, or invested heavily in a startup year. If your Schedule C or K-1 shows a loss exceeding $305,000, the portion above that threshold cannot be used to offset wages, investment income, or other non-business income in 2025. It rolls forward instead.

Self-employed filers using Oil and gas deduction investments or other loss-generating strategies must account for this cap when modeling their tax position. Losses above the threshold carry forward rather than disappear, but the timing shift affects cash flow planning.

New Schedule 1-A and what it means for self-employed filers

The IRS introduced Schedule 1-A for the 2026 filing season to capture the new above-the-line deductions enacted under the One Big Beautiful Bill Act. For self-employed individuals, the relevant provisions are:

• No tax on tips (Section 70201): Self-employed individuals who receive tips in roles that traditionally and customarily received tips prior to 2025 (such as hairstylists, estheticians, and certain beauty service providers who file Schedule C) may qualify. However, self-employed individuals operating a specified service trade or business under Section 199A are explicitly excluded from this deduction.
• No tax on overtime (Section 70202): This deduction applies to FLSA-required overtime compensation reported on a W-2 or equivalent statement. Strictly self-employed individuals without W-2 income generally do not benefit directly from this provision. However, owners who also pay themselves W-2 wages through an S Corporation may qualify for the portion of their compensation that represents FLSA overtime.
• Car loan interest deduction (Section 70203): For tax years 2025 through 2028, qualified passenger vehicle loan interest on vehicles purchased after December 31, 2024, is deductible up to $10,000 per year. These supplement, rather than replace, the existing Vehicle expenses deduction for business-use vehicles, allowing self-employed individuals with mixed-use vehicles to claim both.

How much the new law saves a self-employed filer in 2026

Consider a single self-employed marketing consultant with $185,000 in gross revenue and $45,000 in business expenses, producing net self-employment income of $140,000 for the 2026 tax year.

Without the OBBB Act (what 2026 would have looked like under prior law):

1. Net self-employment income: $140,000
2. Self-employment tax deduction (half of SE tax): $9,892
3. Adjusted gross income: $130,108
4. QBI deduction: $0 (the 20% deduction expired after December 31, 2025, without the OBBB Act)
5. Standard deduction (TCJA-only 2026, inflation-adjusted): $15,300
6. Taxable income: $114,808
7. Estimated federal tax: approximately $20,172

With the OBBB Act for the 2026 tax year:

• Net self-employment income: $140,000
• SE tax deduction: $9,892
• Adjusted gross income: $130,108
• QBI deduction at 20% (permanent under Section 70105): $26,022
• Enhanced standard deduction (single): $16,750
• Taxable income: $87,336
• Estimated federal tax: approximately $14,905
• Estimated annual savings: approximately $5,267

That $5,267 in savings does not include any equipment expensing under 100% bonus depreciation or Section 179, any R&D deductions, or contributions to a Roth 401k or Health savings account. Each of those strategies compounds the benefit further.

Augusta rule and S Corporation planning in 2026

Self-employed individuals operating from home have two distinct opportunities under the OBBB Act. The permanent QBI deduction creates a strong incentive to evaluate whether a Late S Corporation elections makes sense. S Corporations allow owners to split income between W-2 wages and pass-through distributions, with the distribution portion qualifying for the 20% QBI deduction and avoiding self-employment tax.

Home-based business owners can also use the Augusta rule to rent their primary residence to their business for up to 14 days per year on a tax-free basis. The business deducts the rent as an ordinary expense, while the rental income is excluded from the owner's gross income.

For filers in high-tax states, reviewing 2026 California State Tax Deadlines or 2026 New York State Tax Deadlines is important, as state conformity to OBBB Act provisions varies and estimated payment deadlines differ from federal schedules.

Frequently asked questions

Q: Does the OBBB Act affect my self-employment tax rate?

A: No. The OBBB Act did not change the self-employment tax rate, which remains at 15.3% on net self-employment income up to the Social Security wage base and 2.9% above it. You can still deduct half of your SE tax as an above-the-line deduction. The Act's QBI deduction and other provisions reduce your federal income tax but do not affect the SE tax itself.

Q: Can small businesses claim the retroactive R&D spending election?

A: Yes. Section 70302 allows eligible small businesses (those with average annual gross receipts of $31 million or less for the three prior tax years) to elect retroactive application of Section 174A for tax years beginning after December 31, 2021. The election must be made within one year of the Act's enactment and requires filing amended returns for each affected year.

Q: How does the excess business loss limit affect my Schedule C loss this year?

A: If your 2025 Schedule C shows a net loss, Section 461(l) limits the portion of that loss you can use to offset non-business income (such as wages or investment income) to $305,000 for single filers. Any excess loss above that threshold becomes a net operating loss carryforward for future tax years. The $305,000 figure is indexed annually for inflation, so verify the current threshold when filing.

Q: Is the no-tax-on-tips deduction available to self-employed hairstylists and estheticians?

A: It depends on whether your business qualifies as a specified service trade or business (SSTB) under Section 199A. If your beauty services business is not classified as an SSTB, you may qualify for the tip income deduction under Section 70201. Self-employed individuals in SSTBs are explicitly excluded. Review IRS Publication 334 and any IRS guidance on qualifying occupations before claiming this deduction.

Q: How does the enhanced QBI deduction interact with my Traditional 401k contributions?

A: Traditional 401k contributions reduce your adjusted gross income, which in turn reduces your net qualified business income and the 20% QBI deduction. For most self-employed filers below the income threshold, the retirement contribution still yields a larger net tax benefit than the QBI reduction. Still, it is worth running the calculation before year-end.
