State corporate income tax update: What’s happened so far in 2017

Inside Deloitte

In this edition of Inside Deloitte, Shona Ponda, Elil Shunmugavel Arasu, Kathryn Jeffery, and Anna Uger of Deloitte Tax LLP, provide an overview of some state corporate income tax legislative changes that have been enacted during the 2017 state legislative sessions, as well as some related taxpayer considerations.

Introduction

The state legislative process is often lengthy, intricate, and complicated, with competing interests and varying influences from multiple directions. The 2017 legislative season has been no exception—especially considering the uncertainty over and anticipation of federal tax reform,1 coupled with growing state budgetary pressures to fund such areas as health care, education, transportation, and infrastructure.

Continuing a trend seen last year, overall revenue growth among the states has been slow.2 As a result, numerous corporate income-tax-related bills were considered in the states, addressing a wide range of issues, including nexus; tax base; business income; apportionment and market-sourcing; filing methods, unitary combination, and water’s-edge elimination; tax havens; tax rates; and tax administration and amnesty. Some of the bills were enacted into law, while others were tabled for possible reconsideration next year.

In 2017 states have continued to pass legislation regarding the due dates of the corporate income tax returns in response to the passage of the Surface Transportation and Veterans Health Care Choice Improvement Act of 2015,3 which revised the due dates for the federal partnership and corporate income tax returns. That federal law, which was signed by President Obama July 31, 2015, had pressed state taxing authorities to clarify whether there was an effect on their tax return due dates.

With most state legislative sessions having ended for 2017, this article highlights, jurisdiction by jurisdiction, some of the corporate income tax legislative changes that have been enacted thus far.
