1099 vs W2 for Cpa in Illinois: 2026 Tax Guide
Published on 2026-05-17
How Cpas in Illinois Choose Between W2 and 1099
If you are a CPA working in Illinois, you might be offered two very different ways to get paid. One is a standard salary with benefits (W2), and the other is a project-based rate (1099). In 2026, the tax landscape for CPAs has changed slightly, making it even more important to run the numbers before signing a contract.
Historically, CPAs in Illinois have seen a push toward self-employment due to the flexibility it provides. However, that flexibility comes with the burden of self-employment tax and the cost of your own benefits.
Example: $100,000 Annual Income Comparison
| Factor | W2 Cpa | 1099 Cpa |
|---|---|---|
| Gross Salary/Fees | $100,000 | $100,000 |
| Employment Tax | -$7,650 | -$14,130 |
| Federal Tax | -$13,614 | -$7,971 |
| State Tax (Illinois) | -$4,208 | -$3,858 |
| Estimated Take Home | $74,528 | $74,042 |
Specific Deductions for a Cpa
As a 1099 CPA, you can deduct industry-specific expenses that a W2 employee cannot. This might include:
- Specialized software and subscriptions
- Continuing education and certifications
- Equipment and tech hardware
- Client entertainment and business meals (usually 50% deductible)

Should I form an LLC in Illinois?
Many CPAs form an LLC for liability protection. However, an LLC by itself doesn't change your taxes unless you elect S-Corp status, which can save you on SE taxes if your income is high enough.
Can I deduct my Illinois home office?
Yes, if the space is used 100% exclusively for your CPA business. You can use the simplified deduction ($5/sqft) or actual costs.
How do I handle Illinois health insurance?
1099 CPAs must buy their own insurance via the marketplace or private brokers. The good news is those premiums are usually tax-deductible.
