Our tax experts continuously monitor the evolution of state and local tax rules in all 50 states, staying on top of legislative, regulatory, and precedent-setting developments so you and your staff don't have to.

We can help you uncover opportunities for tax savings and refunds through new filing positions, mitigate risk with voluntary disclosure and amnesty programs, and proactively identify reductions in overall state tax liability through realignment of business activities or operations. We provide you with sound supporting evidence for tax positions and strengthen planning scenarios through close collaboration with your entire Plante Moran service team.

From nexus review and planning, voluntary disclosure representation, and audit and controversy representation to unitary analysis, apportionment and allocation review, and tax ruling requests, we can help you feel confident in your state and local tax positions.
