Your Springfield
Business Deserves Better.
Most Springfield businesses overpay on taxes because their CPA is reactive, filing returns instead of building strategy. We work with you year-round to optimize your entity structure, minimize self-employment tax, and keep more of what you earn.
Quick Answer
Taxstra is a Springfield, IL CPA firm for small business owners: S-Corp elections and reasonable compensation, Illinois PTET filings that work around the SALT cap, ADP payroll, monthly bookkeeping, and year-round advisory for contractors, restaurants, medical practices, and professional services. It starts with a free initial consultation at the Springfield office or via video.
Built for Springfield Business
Springfield's economy is unique. As the state capital, a significant portion of local business comes from government contracts, state agency vendors, and public-sector adjacent services. Whether you're a contractor bidding on state projects, a restaurant serving the Capitol lunch crowd, or a medical practice in the growing west-side corridor, your tax situation has Springfield-specific complexities.
The Illinois Department of Revenue (IDOR) is more active in Springfield than anywhere else in downstate Illinois. Sales tax audits, use tax assessments, and withholding compliance issues are common. You need a CPA who handles these regularly, not one who Googles the answer when you get a notice.
We also understand the prevailing wage landscape that affects Springfield-area contractors, the Illinois Pass-Through Entity Tax (PTET) that can save business owners thousands annually, and the S-Corp compensation strategies that reduce self-employment tax without triggering an IRS audit.

S-Corp Election
The single most impactful strategy for profitable businesses. By electing S-Corp status and setting reasonable compensation, you take a meaningful share of your profit out of self-employment tax entirely.
S corp election guideIllinois PTET
The Pass-Through Entity Tax allows your S-Corp or partnership to pay Illinois income tax at the entity level, making it deductible on your federal return and bypassing the $40,000 SALT cap. For qualifying owners, it turns state tax you already pay into a federal deduction.
PTET workaroundRetirement Stacking
A Solo 401(k) ($72K for 2026) paired with a Cash Balance Plan can shelter $150K to $300K+ from federal income tax annually. For profitable Springfield business owners, this is the most powerful wealth-building tool available.
