State and Local Tax (SALT) Services

Multi-State Tax Strategy & Compliance for Growing Businesses Across Key Industries

Today’s business landscape demands that companies be agile—not just in operations, but in how they manage complex tax obligations. At Berndt CPA, we specialize in helping businesses across Southern Wisconsin navigate the ever-changing world of state and local tax (SALT) regulations. Whether you’re expanding across state lines, undergoing a sales tax audit, or managing multiple nexus points, we deliver clarity, compliance, and confidence.

We serve organizations in diverse industries including associations, construction, life sciences, manufacturing, non-profits, pharmacies, professional services, real estate, hospitality, retail, and technology, each of which faces its own SALT-related challenges.

Why State and Local Tax Planning Matters

In today’s interconnected economy, many businesses operate beyond the borders of a single state—but state tax law hasn’t caught up. Each jurisdiction has unique and often inconsistent rules for income tax, sales and use tax, and business activity nexus. If you’re not proactively managing compliance, you’re at increased risk for costly penalties, interest, or state-led audits.

Berndt CPA helps you anticipate risks, meet your filing requirements, and identify opportunities for tax savings, credits, and disclosures before issues arise.
