Illinois Update on Extension of Filing Deadline

Governor Pritzker announced that Illinois is extending the individual income tax filing and payment deadline for tax year 2020 from April 15, 2021 to May 17, 2021. The filing extension takes effect automatically, so no further action is required by taxpayers. The Illinois Department of Revenue will continue to process tax refunds for those filing ahead of the deadline. The filing extension does not apply to estimated tax payments that are due on April 15, 2021: those payments are still due on April 15 and can be based on either 100% of estimated or 90% of actual liability for 2021, or 100% of actual liabilities for 2019 or 2020. ( Gov. Pritzker Announces Income Tax Filing Extension, 03/18/2021 .)

Illinois Annual Sales and Use Tax Nexus Summary

The Illinois Department of Revenue issued a general information in November on ST 20-0017-GIL in response to the annual survey. In the letter, the Department notes that nexus in Illinois includes marketplace facilitators who have met the thresholds of $100,000 in sales or the cumulatively reaching 200 or more separate transactions through the marketplace for sales of tangible personal property. The thresholds are determined by examining gross receipts and number of transactions excluding sales for reseal, sales of tangible personal property that are required to be registered with an Illinois agency such as vehicles or watercrafts, and sales made through the marketplace on behalf of a marketplace seller or marketplace facilitator subject to Retailers’ occupation Tax.

The General Letter provides a definition for marketplace sellers as a person or business that sells or offers tangible personal property through a marketplace operated by an unrelated third-party marketplace facilitator. A marketplace seller is only responsible for Illinois Use Tax liability on sales to Illinois customers and will not be held responsible for the collection and remittance of Illinois Use Tax when a marketplace facilitator fails to correctly collect and remit tax. If the marketplace facilitator can demonstrate the incorrect calculations is due to the marketplace sellers incorrect or insufficient information, the marketplace seller is held liable for any Illinois Use Tax due.

The Department clarified that viewing and downloading of videos, text, and other data over the interest is not considered to be tangible personal property subject to Retailers’ Occupation Tax and Use tax liability. The transfer of canned software, or updates to canned software is considered transfer of tangible personal property and therefore subject to Retailers’ Occupation Tax and Use tax liability. This would include sales of canned software downloaded electronically which would be taxable.

Relief for Eating and Drinking Establishments

In an effort to assist eating and drinking establishments impacted by the COVID-19 outbreak, effective immediately, the Illinois Department of Revenue (IDOR) is waiving any penalty and interest that would have been imposed on late Sales Tax payments from qualified taxpayers.

Taxpayers who are eligible for relief from penalties and interest on late Sales Tax payments are those operating eating and drinking establishments that incurred a total Sales Tax liability of less than $75,000 in calendar year 2019.

Qualified taxpayers will not be charged penalties or interest on late payments for Sales Tax liabilities reported on Form ST-1, Sales and Use Tax and E911 Surcharge Return, that are due for the February, March, and April 2020 reporting periods.

For most qualified taxpayers, IDOR will automatically waive penalties and interest. If a taxpayer receives a notice from IDOR that imposes penalties and interest that should have qualified for a waiver, the taxpayer can respond to the notice indicating as such. IDOR will review the response and grant relief, if appropriate. Qualified taxpayers are required to file Form ST-1 for each reporting period by their original due dates, even if they are unable to make a payment. To qualify for relief, taxpayers must pay their liabilities due in March, April, and May 2020 on four dates starting on May 20, 2020.

The required payment schedule for liabilities reported on Form ST-1 is as follows:

  • One quarter (1/4) of the liability for the February, March, and April 2020 reporting periods is due May 20, 2020.
  • One quarter (1/4) of the liability for the February, March, and April 2020 reporting periods is due June 22, 2020.
  • One quarter (1/4) of the liability for the February, March, and April 2020 reporting periods is due July 20, 2020.
  • One quarter (1/4) of the liability for the February, March, and April 2020 reporting periods is due August 20, 2020.

This includes quarterly filers reporting liabilities on Form ST-1 for January, February, and March. Taxpayers must begin making full payment on the scheduled due date for liabilities beginning with the May 2020 reporting period, which is due June 22, 2020, and all reporting periods following.
