State and local tax (SALT) issues are complex, jurisdiction-specific, and constantly evolving. When your firm encounters a multi-state client, nexus question, or apportionment challenge, TaxProExchange connects you with CPAs who specialize in SALT and multi-state compliance.

Our directory includes professionals with deep experience in state income tax, sales tax, nexus analysis, apportionment, credits and incentives, and controversy. Whether you need a consultant for a specific state return, a reviewer for a multi-state S-corp, or a referral partner for ongoing SALT work, you'll find verified professionals with the credentials and experience you need.

Search by state, specialization (SALT, 1120-S, partnership, nexus), and availability to find the right expert for your engagement. Reach out directly to discuss case details, scope, and fees—no platform fees, no barriers to connection.

When to Use Multi-State & SALT Expertise for Tax Firms

  • Your client operates in multiple states and you need expertise in nexus, apportionment, or state-specific rules
  • You're handling a complex S-corp or partnership with multi-state activities and need a second set of eyes
  • Your firm wants to expand SALT capabilities without hiring a full-time specialist
