State taxing authorities address COVID-19 filing and business change

Apr 02, 2020

Almost every state with a personal income tax and most states with a corporate income tax have provided filing and/or payment  relief through legislative and regulatory action or by order of the state’s governor. Based on conformity, many states had  already extended their income tax filing deadlines to the federal filing extension. However, conformity to the Internal Revenue Code does not necessarily mean conformity to filing dates. For more information regarding deadline extensions and federal conformity, please read our alert, State conformity to federal COVID-19 extensions.

We will continue to monitor state developments regarding extensions and are working closely with the AICPA to provide updates as they occur. A more detailed tracking chart is available on the AICPA’s website here. Please note that state guidance continues to evolve, including in states where previous guidance was provided.

The following is a summary of selected state responses in wake of the coronavirus:

There is much uncertainty as businesses and governments respond to the numerous and disruptive effects of the COVID-19 pandemic. In light of this uncertainty, state and local taxing authorities are providing guidance related to filing and penalty relief due to coronavirus on an almost daily basis. This relief may be specific to certain taxpayers and certain tax types. Additionally, taxpayers should be aware that many taxing authorities are adjusting their hours and operations schedules to protect both their employees and the public.

As the situation with COVID-19 continues to unfold, states will be monitoring economic impacts and putting into place a wide variety of relief measures, most of which will be targeted at providing cash flow relief to businesses and individuals. Due date extensions like those discussed above provide additional time to pay tax liabilities, and may help near-term cash liquidity and flexibility. In the current environment, it is important to keep abreast of deadline changes, and to determine whether it is better to pay now or take advantage of short-term cash flow relief.

Income tax is not the only state or local tax with recent filing relief. For more information regarding sales tax filing or payment relief, please read our alert State and local sales tax extensions and relief due to COVID-19.
