Texas vs Illinois LLC Formation 2026: Costs, Taxes & Compliance Comparison
---
---
Introduction: Quick Verdict and Key Differentiator
Texas wins for cost-conscious founders and profitable businesses; Illinois wins for service professionals prioritizing lower upfront costs. Texas charges $300 to file your Certificate of Formation (Tex. Bus. Org. Code § 101.051) with zero state income tax, while Illinois charges $150 but imposes 4.95% individual income tax and 1.5% replacement tax on pass-through entities (35 ILCS 5/). Texas exempts LLCs earning under $2,650,000 annually from franchise tax (Tex. Tax Code § 171.0002), creating substantial long-term savings. Illinois has no franchise tax but charges $75 annually for compliance (805 ILCS 180/50-1).
The critical differentiator: Texas has no state income tax; Illinois does. For a profitable LLC generating $100,000 in annual income, you'll pay $5,950 in Illinois taxes (4.95% + 1.5%) versus $0 in Texas—assuming Texas revenue stays under the $2.65M threshold. This single factor compounds annually and typically offsets Illinois's lower formation fee within 12 months of profitability.
FAQ: Three Essential Questions
1. Which state costs less to form and maintain an LLC?
Texas charges $300 for your Certificate of Formation (Tex. Bus. Org. Code § 101.051), while Illinois charges $150 for Articles of Organization (805 ILCS 180/5-5). Illinois's $150 savings disappears when you factor in annual compliance. Texas requires a free Public Information Report due May 15 annually (Tex. Tax Code § 171.0001), but Illinois mandates a $75 annual report due before your anniversary month (805 ILCS 180/50-1). Over five years, Texas saves $225 in filing fees alone.
Formation and Annual Compliance Costs:
| Item | Texas | Illinois |
|---|---|---|
| Certificate/Articles Filing | $300 (Tex. Bus. Org. Code § 101.051) | $150 (805 ILCS 180/5-5) |
| Name Reservation (optional) | $40 (120 days) | $25 (90 days) |
| DBA Filing (if needed) | $25 (Tex. Bus. Org. Code § 5.053) | $120 (805 ILCS 180/1-10) |
| Annual Report Fee | $0 (Tex. Tax Code § 171.0001) | $75 (805 ILCS 180/50-1) |
| 5-Year Total (no DBA) | $300 | $525 |
| 5-Year Total (with DBA) | $325 | $645 |
Winner: Texas. You save $225 over five years on filing fees alone. If you need a DBA, Texas costs $25 while Illinois charges $120—a $95 difference per filing. Texas's zero annual report fee versus Illinois's $75 annual requirement creates cumulative savings of $375 over five years.
2. What are the ongoing tax obligations in each state?
Texas imposes no state income tax on LLC members (no provision in Tex. Tax Code). However, Texas requires franchise tax of 0.75% of taxable margin for most businesses, or 0.375% for retail/wholesale operations—but only if your annualized revenue exceeds $2,650,000 (Tex. Tax Code § 171.0002). Below that threshold, you owe $0 in state franchise tax.
Illinois taxes individual members at 4.95% on their distributive share of LLC income (35 ILCS 5/). Additionally, pass-through entities like LLCs owe a 1.5% replacement tax on Illinois-taxable income (35 ILCS 5/). These taxes apply regardless of revenue size—there is no exemption threshold.
Annual Tax Obligations by Revenue Level:
| Annual Revenue | Texas Franchise Tax | Illinois Income Tax | Illinois Replacement Tax | Total Illinois Tax |
|---|---|---|---|---|
| $100,000 | $0 (under $2.65M threshold) | $4,950 (4.95%) | $1,500 (1.5%) | $6,450 |
| $500,000 | $0 (under $2.65M threshold) | $24,750 (4.95%) | $7,500 (1.5%) | $32,250 |
| $1,000,000 | $0 (under $2.65M threshold) | $49,500 (4.95%) | $15,000 (1.5%) | $64,500 |
| $2,650,000 | $0 (at threshold) | $131,175 (4.95%) | $39,750 (1.5%) | $170,925 |
| $5,000,000 | $29,625 (0.75% of $3.35M excess) | $247,500 (4.95%) | $75,000 (1.5%) | $322,500 |
Winner: Texas for small businesses. If your LLC generates under $2.65M in revenue, you pay $0 in state franchise tax. Illinois charges 4.95% income tax plus 1.5% replacement tax on all pass-through income, regardless of size. A $100,000 profit triggers $6,450 in Illinois taxes versus $0 in Texas (assuming revenue under the threshold). At $1,000,000 in revenue, you save $64,500 annually by operating in Texas.
3. Which state offers better liability protection and operational flexibility?
Both Texas and Illinois recognize single-member LLCs (Tex. Bus. Org. Code § 101.051; 805 ILCS 180/5-5) and allow foreign owners without residency requirements. Texas provides standard charging order protection under Tex. Bus. Org. Code § 101.112, limiting creditors to a charging order remedy rather than forced dissolution. Illinois offers identical charging order protection (805 ILCS 180/30-30).
Texas allows Series LLCs under Tex. Bus. Org. Code §§ 101.601–101.636, enabling you to create separate series with distinct assets and liabilities within one LLC at no extra cost. Illinois permits Series LLCs (805 ILCS 180/37-40) but charges an additional $400 filing fee for series formation. Both states allow Professional LLCs for licensed professionals (Tex. Bus. Org. Code Ch. 301; 805 ILCS 185/). Illinois uniquely permits Low-Profit LLCs (805 ILCS 180/1-5), while Texas does not.
