What Are the Biggest 2026 Tax Changes for Chicago Businesses?
Quick Answer: The biggest 2026 changes include higher 1099 thresholds, larger Section 179 limits, a mid-year mileage increase, and permanent bonus depreciation under OBBBA.
The 2026 tax changes Chicago business owners must track come mostly from the One Big Beautiful Bill Act (OBBBA). This law made several Tax Cuts and Jobs Act provisions permanent. In addition, it introduced new reporting rules and deduction limits. As a result, both federal and Illinois planning shifted this year. A strong proactive tax strategy plan now matters more than ever.
Chicago entrepreneurs feel these changes across payroll, purchasing, and vendor payments. Furthermore, the timing of purchases and payments affects your 2026 bill directly. Therefore, understanding each rule helps you plan smart before year-end.
Federal Changes at a Glance
Several OBBBA provisions took effect for tax years beginning after December 31, 2025. Consequently, 2026 is the first full year many of them apply. According to the IRS newsroom guidance, businesses must update systems now.
- Form 1099-NEC and 1099-MISC threshold increased to $2,000.
- Section 179 expensing rose to $2.5 million, with a $4 million phase-out.
- Bonus depreciation became permanent at 100%.
- Dependent care assistance limit rose to $7,500 from $5,000.
Why These Changes Matter Locally
Chicago has a high combined sales tax and an active business fine program. Moreover, Mayor Brandon Johnson has repeatedly pushed new business taxes. Therefore, federal savings help offset a heavier local burden. Many Chicago small business owners use these federal breaks to stay competitive with neighboring states.
Pro Tip: Update your bookkeeping software now so 1099 and payroll fields reflect the new 2026 thresholds.
How Do 2026 Federal Tax Changes Affect Chicago Business Owners?
Quick Answer: Federal 2026 changes lower reporting burdens, boost equipment write-offs, and raise the business mileage deduction to 76 cents mid-year.
Federal rules drive most tax planning for Illinois businesses. Because OBBBA made the 20% qualified business income (QBI) deduction permanent, pass-through owners keep a valuable break. As a result, S corporations, LLCs, and sole proprietors continue benefiting in 2026. This permanence removes the uncertainty that once loomed at year-end 2025.
The Mid-Year Mileage Rate Increase
The IRS took an unusual step in 2026. It raised the standard mileage rate mid-year due to rising fuel prices. Consequently, Chicago business owners now use two rates for 2026.
- 72.5 cents per mile for business miles driven January 1 through June 30, 2026.
- 76 cents per mile for business miles driven on or after July 1, 2026.
- 14 cents per mile stays fixed for charitable driving.
This detail comes directly from an IRS standard mileage rates page. Therefore, keep separate mileage logs for each half of the year. Otherwise, you risk understating your deduction.
Entity Choice Still Drives Savings
Because the QBI deduction is permanent, entity structure remains central. Many owners weigh LLC versus S corporation status to reduce self-employment tax. In fact, the right structure can save thousands each year. Our entity structuring guidance helps you compare the options. You can also run numbers with the LLC vs S-Corp Tax Calculator for Dover, Delaware to estimate 2026 savings.
| Item | 2025 (Prior Year) | 2026 |
|---|---|---|
| Business mileage rate | 70 cents | 72.5 then 76 cents |
| 1099-NEC threshold | $600 | $2,000 |
| Section 179 limit | $1.25 million | $2.5 million |
Did You Know? Bonus depreciation returned to a permanent 100% in 2026, letting you fully expense qualifying assets.
What Changed With 1099 Reporting in 2026?
Quick Answer: The 1099-NEC and 1099-MISC threshold rose from $600 to $2,000, and 1099-K reverted to $20,000 and 200 transactions.
Reporting rules changed meaningfully for 2026. For payments made after December 31, 2025, the dollar threshold for Forms 1099-MISC and 1099-NEC increased from $600 to $2,000. Therefore, you file fewer forms for small vendor payments. However, you must still track every payment carefully. The IRS Form 1099-NEC page confirms these filing rules.
The 1099-K Reversal
OBBBA also restored the older 1099-K rules. Consequently, third-party payment providers now use a $20,000 gross receipts and 200 transactions test for 2026. This reversal ends the confusing gradual lowering toward $600. As a result, many gig workers and small sellers receive fewer forms. Nevertheless, you still owe tax on all business income.
What This Means for Contractors
Independent professionals should not relax reporting habits. Even without a form, income remains taxable. Therefore, keep clean records all year. Our self-employed tax planning resources help freelancers stay compliant. Furthermore, accurate records protect you during any IRS review.
Pro Tip: Even under the higher $2,000 threshold, collect a Form W-9 from every vendor you pay.
How Can You Maximize 2026 Equipment Deductions?
Free Tax Write-Off FinderQuick Answer: Combine the $2.5 million Section 179 limit with permanent 100% bonus depreciation to fully expense equipment purchased in 2026.
Equipment purchases offer some of the largest 2026 savings. The Section 179 expensing limit rose to $2.5 million, with a $4 million investment phase-out. Therefore, most Chicago small businesses can fully expense qualifying purchases. In addition, bonus depreciation now sits at a permanent 100%. These two tools work together powerfully.
A Simple Example Calculation
Imagine a Chicago contractor buys $180,000 of equipment in 2026. Under Section 179, the full amount qualifies for immediate expensing. As a result, taxable income drops by $180,000. Assuming a combined federal and Illinois rate near 30%, that saves roughly $54,000. Consequently, timing your purchases before December 31 matters greatly.
- Equipment cost: $180,000
- Section 179 deduction: $180,000
- Estimated tax savings: about $54,000
Section 179 Versus Bonus Depreciation
Both tools accelerate deductions, yet they differ. Section 179 has income limits and cannot create a loss. Bonus depreciation, however, can create a net operating loss. Therefore, strategic owners often combine them. The SBA business tax guide explains how these deductions support growth. Our tax preparation and filing team handles the paperwork correctly.
| Feature | Section 179 | Bonus Depreciation |
|---|---|---|
| 2026 limit | $2.5 million | 100% (no dollar cap) |
| Can create a loss? | No | Yes |
| Phase-out threshold | $4 million | None |
Pro Tip: Place equipment in service before December 31, 2026 to claim the deduction this year.
What Illinois and Chicago Rules Apply in 2026?
Quick Answer: Illinois keeps its flat 4.95% income tax in 2026, while Chicago maintains a 10.25% combined sales tax rate.
State and city rules add complexity for Chicago owners. Illinois still applies a flat 4.95% individual income tax rate for 2026. Meanwhile, Chicago carries the state’s highest combined sales tax at 10.25%. Therefore, local purchasing and pricing decisions carry real tax weight. Working with Tax Preparation Near Me in Illinois keeps you compliant with both layers.
Watch Proposed Illinois Changes
Illinois lawmakers keep debating major tax shifts. For example, a surtax on income above $1 million resurfaces regularly. In addition, some officials want to broaden the sales tax to services. Neither change advanced to voters this year. Nevertheless, business owners should watch these proposals closely. According to the Illinois Department of Revenue, current rates remain unchanged for now.
Chicago Compliance and Fines
Chicago aggressively enforces business fines. In 2026, the city fined delivery firms hundreds of thousands for lane violations. Moreover, unpaid fines can block licenses and permits. Therefore, staying current protects your ability to operate. Many owners choose ongoing tax advisory support to avoid costly surprises.
