Income Tax Office


The Treasury Department and Internal Revenue Service announced that the federal income tax filing due date is automatically extended from April 15, 2020, to July 15, 2020.

The City of Portland will be following the IRS based on Sec. 141.664 Sec 64. The Income Tax Administrator will be moving the date due from April 30th to July 31st.

Taxpayers can defer income tax payments due on April 30, 2020, to July 31, 2020, without penalties and interest, regardless of the amount owed. This means we will give all Portland taxpayers until July 31st to file. This deferment applies to all taxpayers, including individuals, trusts and estates, corporations and other non-corporate tax filers as well as those who pay self-employment tax.

Taxpayers do not need to file any additional forms or call us to qualify for this automatic tax filing and payment relief. Individual taxpayers who need additional time to file beyond the July 31st deadline, can request a filing extension. Please remember to sign your tax return. Failure to do so will cause the Income Tax Department to contact you to make arrangements to obtain your signature.

There will not be any penalty or interest on tax due unless it was for failure to make estimated payments. All court dates have been postponed or dismissed for 90-days. If you have an automatic payment arrangement or payment plan and need to make adjustments during this time please email or call 517-647-2941.

We will be checking our voicemails and emails during the mandated stay at home order.
