What is the One Big Beautiful Bill Act and how does it affect self-employed workers?

The One Big Beautiful Bill Act (enacted 2026) is the largest tax reform since the 2017 TCJA. It modifies federal income tax brackets, adjusts standard deduction amounts, updates QBI (Section 199A) deduction rules, increases retirement contribution limits for self-employed individuals, and changes multiple business deduction thresholds. For 1099 contractors and freelancers, the most impactful changes are the inflation-adjusted tax brackets, higher retirement caps, and clarified home office deduction rules.

Did SE tax rates change in 2026?

The SE tax rate remains 15.3% (12.4% Social Security + 2.9% Medicare) for 2026. However, the Social Security wage base increased to $176,100 (up from $168,600 in 2025). Self-employed individuals with net earnings above $176,100 only pay the 2.9% Medicare portion on the excess. Additionally, a 0.9% Additional Medicare Tax applies to earnings above $200,000 (single) or $250,000 (married filing jointly).

What changed for QBI deduction in 2026?

The 20% Qualified Business Income (QBI) deduction under Section 199A continues in 2026 with updated phase-out thresholds. For single filers, the phase-out begins at $197,300 of taxable income; for married filing jointly, it begins at $394,600. Specified Service Trade or Business (SSTB) limitations still apply, and the W-2 wage/capital limitation kicks in above these thresholds.

How did retirement contribution limits change for self-employed in 2026?

For 2026: Solo 401(k) employee deferral limit is $23,500 ($31,000 if age 50+). SEP IRA and Solo 401(k) total contribution cap (employee + employer) is $70,000. The compensation limit for calculating contributions is $350,000. These increases allow self-employed individuals to defer more income and reduce their current-year tax liability.

Are the 2026 tax changes permanent or temporary?

The 2026 changes under the One Big Beautiful Bill Act are mostly permanent provisions, unlike the 2017 TCJA which had many provisions set to expire after 2025. However, some business deduction enhancements are scheduled for review in 2030. Self-employed individuals should plan based on current law, with the understanding that future Congresses may modify these provisions.

1. Federal Income Tax Brackets — 2026 vs 2025

The 2026 tax brackets have been adjusted for inflation. Here's how they compare to 2025:

Single Filers

Tax Rate	2025 Income Range	2026 Income Range
10%	$0 – $11,925	$0 – $12,200
12%	$11,926 – $48,475	$12,201 – $49,500
22%	$48,476 – $103,350	$49,501 – $105,600
24%	$103,351 – $197,300	$105,601 – $201,500
32%	$197,301 – $250,525	$201,501 – $255,800
35%	$250,526 – $626,350	$255,801 – $639,500
37%	Over $626,350	Over $639,500

Married Filing Jointly

Tax Rate	2025 Income Range	2026 Income Range
10%	$0 – $23,850	$0 – $24,400
12%	$23,851 – $96,950	$24,401 – $99,000
22%	$96,951 – $206,700	$99,001 – $211,200
24%	$206,701 – $394,600	$211,201 – $403,000
32%	$394,601 – $501,050	$403,001 – $511,600
35%	$501,051 – $751,600	$511,601 – $767,400
37%	Over $751,600	Over $767,400

💡 What This Means for You: Bracket thresholds are about 2-3% higher in 2026, which means slightly more of your income falls into lower brackets — a modest tax cut for most self-employed workers. Use our 1099 tax calculator to see your exact bracket.

2. Standard Deduction Changes

Filing Status	2025	2026
Single	$15,000	$15,300
Married Filing Jointly	$30,000	$30,600
Head of Household	$22,500	$22,950
Married Filing Separately	$15,000	$15,300

The standard deduction increased modestly across all filing statuses. If your itemized deductions (mortgage interest, charitable contributions, state/local taxes up to $10K SALT cap, medical expenses above 7.5% AGI) don't exceed these amounts, you'll take the standard deduction.

3. Self-Employment Tax & Social Security Wage Base

The SE tax rate remains 15.3% (12.4% Social Security + 2.9% Medicare). However, the Social Security wage base has increased:

Component	2025	2026
Social Security Wage Base	$168,600	$176,100
Max Social Security Tax (SE)	$20,906	$21,836
Additional Medicare Tax Threshold (Single)	$200,000	$200,000 (unchanged)
Additional Medicare Tax Threshold (MFJ)	$250,000	$250,000 (unchanged)
Additional Medicare Tax Rate	0.9%	0.9% (unchanged)

⚠️ Important: The wage base increase means you'll pay Social Security tax on an additional $7,500 of net earnings in 2026. If your net profit exceeds $176,100, only the 2.9% Medicare portion applies to the excess — but the 1/2 SE tax deduction (line 15 of Schedule 1) still reduces your AGI.

4. QBI Deduction (Section 199A) — 2026 Updates

The 20% Qualified Business Income deduction continues, with updated phase-out thresholds:

Parameter	2025	2026
Deduction Rate	20% of QBI	20% of QBI (unchanged)
Phase-Out Start (Single)	$191,950	$197,300
Phase-Out Start (MFJ)	$383,900	$394,600
SSTB Limitation	Applies in phase-out range	Applies in phase-out range (unchanged)

The QBI deduction remains one of the most valuable tax breaks for self-employed individuals. It allows you to deduct up to 20% of your qualified business income before calculating your final tax liability. The higher phase-out thresholds in 2026 mean slightly more self-employed workers can claim the full deduction.

💡 SSTB Reminder: If you're in a "Specified Service Trade or Business" (consulting, law, health, financial services, performing arts), your QBI deduction phases out within the income range. Non-SSTB businesses (retail, manufacturing, construction) are not subject to this limitation — only the W-2 wage/capital limit applies above the threshold.

5. Retirement Contribution Limits — SEP IRA & Solo 401(k)

Plan Type	2025 Limit	2026 Limit
Solo 401(k) Employee Deferral	$23,000	$23,500
Solo 401(k) Catch-Up (Age 50+)	$7,500	$7,500 (unchanged)
SEP IRA / Solo 401(k) Total Cap	$69,000	$70,000
Compensation Limit	$345,000	$350,000
IRA (Traditional/Roth)	$7,000	$7,000 (unchanged)
IRA Catch-Up (Age 50+)	$1,000	$1,000 (unchanged)

Use our Retirement Tax Savings calculator (Tab 9) to estimate how much you can contribute and save on taxes.

6. Health Insurance & HSA Contribution Limits

Account Type	2025	2026
HSA — Self-Only Coverage	$4,150	$4,300
HSA — Family Coverage	$8,300	$8,750
HSA Catch-Up (Age 55+)	$1,000	$1,000 (unchanged)
HDHP Minimum Deductible (Self)	$1,600	$1,650
HDHP Minimum Deductible (Family)	$3,200	$3,300

The self-employed health insurance deduction (above-the-line) continues unchanged. HSA contributions provide a triple tax benefit: contributions are deductible, growth is tax-free, and qualified medical withdrawals are tax-free.

7. Business Deductions — Section 179 & Bonus Depreciation

Deduction	2025	2026
Section 179 Expensing Limit	$1,220,000	$1,250,000
Section 179 Phase-Out Threshold	$3,050,000	$3,120,000
Bonus Depreciation	60%	40%
Standard Mileage Rate	$0.70/mile	$0.72/mile

⚠️ Key Change — Bonus Depreciation Phase-Down: Bonus depreciation continues its scheduled phase-down from 100% (2022) to 40% in 2026. It will reach 20% in 2027 and 0% in 2028 unless Congress extends it. If you're planning major equipment purchases, Section 179 may now be more valuable than bonus depreciation.

8. Child Tax Credit & Dependent Care Changes

Credit	2025	2026
Child Tax Credit (per child under 17)	$2,000	$2,000 (unchanged)
CTC Refundable Portion	$1,700	$1,800
CTC Phase-Out Start (Single)	$200,000	$205,000
CTC Phase-Out Start (MFJ)	$400,000	$410,000
Child & Dependent Care Credit Max	$3,000 / $6,000	$3,000 / $6,000 (unchanged)

9. Home Office Deduction — Simplified Option

The simplified home office deduction rate remains at $5 per square foot (max 300 sq ft = $1,500). The regular method (actual expenses by square footage percentage) is unchanged and often yields a larger deduction for high-rent areas.

10. 1099-K Reporting Threshold

The IRS has further lowered the 1099-K reporting threshold for third-party payment platforms (PayPal, Venmo, Stripe, Cash App, Uber, DoorDash):

Year	Threshold
2024	$5,000
2025	$2,500
2026	$600 (final phase)

⚠️ This Affects Millions of Side Gig Workers: Beginning tax year 2026, any platform that processes $600+ in payments to you will issue a 1099-K. This means many casual sellers, side hustlers, and gig workers who never received a 1099 before will now get one. You must report all income regardless of whether you receive a 1099-K.

11. What Has NOT Changed (Still the Same)

SE Tax Rate: Still 15.3% (12.4% SS + 2.9% Medicare)
1/2 SE Tax Deduction: You still deduct 50% of SE tax above-the-line
Quarterly Estimated Tax Due Dates: April 15, June 15, September 15, January 15
$400 Filing Threshold: Net SE earnings of $400+ still trigger filing requirement
SALT Cap: $10,000 state/local tax deduction limit remains
Capital Gains Rates: 0% / 15% / 20% long-term rates unchanged
Net Investment Income Tax: 3.8% above $200K (single) / $250K (MFJ) unchanged
Gig Worker Classification: No federal reclassification law passed; 1099 vs W2 rules unchanged

12. Action Plan: What Self-Employed Workers Should Do Now

Recalculate your quarterly estimated payments. With updated brackets and the higher Social Security wage base, your 2026 safe-harbor estimate may have changed. Use Tab 2 of our calculator.
Max out retirement contributions before year-end. The Solo 401(k) $23,500 deferral + employer contribution can shelter significant income. Establish your plan by December 31.
Track business expenses meticulously. With the $600 1099-K threshold, platforms will report more of your income. Every deductible expense matters. See our mileage log guide.
Consider S-Corp election if net profit exceeds ~$70,000. The SE tax savings from S-Corp distributions grow more valuable as the wage base rises. Read our comparison →
Review health insurance and HSA strategy. If you have an HDHP, maxing your HSA is one of the most efficient tax moves available to self-employed individuals.
Check if the QBI deduction applies to you. Most self-employed individuals qualify. Use Tab 1 of our calculator to see the estimated deduction.
Plan for 1099-K reporting. If you sell on Etsy, drive for Uber, or freelance on Fiverr, expect a 1099-K for 2026 if you earned $600+. Keep clean records of business vs. personal transactions.
