Whether your business operates in all 50 states, a few, or just one, trying to stay current and compliant with income and non-income tax laws and regulations can be time-consuming and often frustrating. The laws are complicated and ever-changing—no matter your business type—C or S corporation, partnership or sole proprietor.

After thoroughly assessing your state and local tax (SALT) needs, Marcum professionals focus on creating a comprehensive and effective tax compliance plan for your business.

With our SALT Controversy Team, our clients will benefit from our:

  • Thorough understanding of the audit process and procedures, from initial contact to resolution (soup to nuts).
  • Understanding of what the auditor knows about the company and common audit practices for each industry (the “question behind the question”).
  • Complete familiarity with what documentation is important to the auditor and what irrelevant information to avoid.
  • Ability to purse alternative procedures such as advance letter rulings or administrative appeals to help close out the audit.
  • Technical mastery of the state taxing jurisdiction’s rules and insight into issues a state tax department is focused on for future decisions.

States have been left by the pandemic with unprecedented budget deficits and will be aggressively pursuing tax reviews. Our team is prepared to help effectively represent our clients before state taxing jurisdictions.
