Small Business Tax Changes 2026: What You Need to Know

Small business tax changes 2026 bring some of the most significant updates in years, driven largely by the One Big Beautiful Bill Act (OBBBA) and annual IRS inflation adjustments. From new 1099 reporting thresholds to higher equipment deduction limits, these changes affect how small businesses file, deduct, and plan for the year ahead.

Reviewing these updates now, before year-end filing season, can help you avoid surprises and take advantage of new savings opportunities.

What’s Driving the 2026 Small Business Tax Law Changes

Most of this year’s small business tax law changes 2026 trace back to the OBBBA, signed into law in 2025, combined with the IRS’s routine inflation-based adjustments.

Together, these updates touch contractor reporting, equipment purchases, pass-through business income, and payroll-related deductions.

1099 Reporting Requirements 2026

The 1099 reporting requirements 2026 bring welcome relief for businesses that rely on contractors:

• The Form 1099-NEC and 1099-MISC reporting threshold rises from $600 to $2,000, with future inflation adjustments
• Backup withholding rules now follow this same $2,000 threshold
• The 1099-K threshold for third-party payment platforms (PayPal, Venmo, etc.) returns to $20,000 and 200 transactions

This reduces the volume of forms many small businesses need to file, but accurate vendor recordkeeping is still essential for tax compliance.

Section 179 Deduction Limits 2026

The Section 179 deduction limits 2026 got a major boost this year. The maximum deduction increases to $2.5 million, with the phase-out threshold starting at $4 million, both indexed for inflation going forward.

For businesses planning equipment purchases, vehicle upgrades, or facility improvements, this expanded limit means more of that spending can be deducted in the year it’s placed in service, rather than depreciated over several years.

Qualified Business Income Deduction 2026

The Qualified Business Income deduction 2026 update is arguably the biggest win for pass-through entities. The 20% QBI deduction for sole proprietors, partnerships, and S-corps is now permanent, offering a minimum $400 deduction for anyone with at least $1,000 of qualified business income.

If your business operates as a pass-through entity, this is worth reviewing with your accountant to confirm you’re capturing the full benefit.

Other 2026 Small Business Tax Deductions to Know

A few additional 2026 small business tax deductions are worth flagging:

• Standard mileage rate increases to 72.5 cents per mile
• Interest expense limitation reverts to the more favorable EBITDA calculation
• Full expensing for qualifying research and experimental costs is now permanent
• Solar and other energy-related credits phase out after 2025

What This Means for Businesses in Western Pennsylvania

For small businesses across the Pittsburgh area and greater Allegheny County, these federal changes still need to be layered against Pennsylvania and local tax obligations. A business claiming the new Section 179 limits or the permanent QBI deduction should confirm how each applies at the state level before filing.
