Illinois Modifies Financial Organization Apportionment and Increases Net Loss Deduction Cap

Authored by: Brandon Mejia and Katie Nguyen, CPA

On June 7, 2024, Governor J.B. Pritzker signed HB 4951 into law, which revises the way financial organizations apportion income to Illinois. For tax years starting on or after December 31, 2024, financial organizations will apportion investment and trading income by the ratio of Illinois-specific receipts to total gross receipts from financial organization activities. This ratio excludes investment and trading income.

Additionally, HB 4951 increases the maximum Net Loss Deduction (NLD) from $100,000 to $500,000 per year for tax years ending between December 31, 2024, and December 31, 2027.

Illinois’ Changes to Remote-Seller Sales Tax Rules Does Not Address PetMeds Challenge

Authored by: Leroy Solis, MBA and Penny Sweeting, CPA

Governor J.B. Pritzker is expected to sign SB 3362, further complicating the state sales tax code for remote sellers.

Pursuant to SB 3362, out-of-state retailers will collect sales tax using destination-based sourcing rules. As such, out-of-state retailers without a physical presence in the state are required to collect applicable local taxes based on the shipping address. In Chicago, the total tax is 10.25% including local taxes. Meanwhile, in-state retailers making remote sales in Illinois only collect sales tax at the point of origin. As such, in-state businesses making remote sales may only have to collect the state’s 6.25% tax.

PetMeds Express is currently challenging the disparate treatment of in-state and out-of-state retailers when it comes to the collection of local sales taxes. SB 3362 does not address PedMed’s litigation winding its way through the Illinois Courts.

Illinois Remote Seller Rules Challenged by PetMeds

Authored by: Katerine Velasquez and Bonnie Susmano, JD, MBA

PetMeds, an online retailer of pet supplies and medications based in Florida, has challenged Illinois’ “leveling the playing field” statute on the following grounds:

  1. The Illinois statute discriminates against interstate commerce, creating an undue burden on out-of-state retailers;
  2. The Illinois Department of Revenue violated the taxpayer's rights to an efficient audit and proper explanation of the alleged liabilities; and,
  3. The Illinois Department of Revenue violated the state's constitution by discriminating against out-of-state taxpayers.

Specifically, Illinois’s “leveling the playing field” statute requires out-of-state remote sellers to collect both state sales tax plus local Retailers Occupation Taxes (“ROT”) based on the ship to address. In contrast, in-state sellers making online sales are only required to collect ROT based on location. ROT rates vary in Illinois from 0% to 5.25%. As such, an instate seller located in a locality with a 0% ROT only has to collect the state’s 6.25% sales tax, even if the order is shipped to a locality where the ROT is 5.25%. In contrast, PetMeds is obligated to collect the 6.25% state sales tax plus the applicable local ROT. This gives in-state retailers as much as a 5.25% price advantage over PetMeds.

This case is presently being heard at the Illinois Independent Tax Tribunal. It seems likely that the Tribunal’s decision will be further appealed, and we will provide updates as they occur. For additional information, the case citation is PetMed Express, Inc. v. Illinois Department of Revenue, Case No. 23 TT 04, Illinois Independent Tax Tribunal (2023).

Illinois Releases Revised Pass-Through Entity Guidance

Authored by: Bonnie Susmano, JD, MBA and Breea Boylan, CPA

The Illinois Department of Revenue released revisions relating to pass-through entities, including PTET guidance. The revisions are specific to “investment partnerships” and include:

  • For tax years ending on or after December 31, 2023, the 90% test for determining if a partnership is an ‘investment partnership” may include the distributive share of income from lower-tier partnerships if the lower-tier partnership is an investment partnership.
  • For tax years ending on or after December 31, 2023, investment partnerships are required to withhold an amount from each applicable nonresident partner.
  • For tax years ending prior to December 31, 2023, and on or after December 31, 2004 - An investment partnership is not subject to replacement tax, and a nonresident partner is not subject to Illinois tax on the income passed through from the investment partnership, unless the partner’s investment in the partnership was made in connection with a business the partner is conducting at least partially within Illinois.

The revisions also noted that Form IL-1000-E, Certificate of Exemption for Pass-through Withholding, does not exempt an investment partnership from investment partnership withholding, and electing to pay PTE tax does not exempt an investment partnership from withholding for its nonresident partners.

If you have questions about the state tax treatment of pass-through entities, please reach out to a member of the Withum SALT Team.

Illinois Declares Relief for Taxpayers Affected by Middle East Conflict

Authored by: Bonnie Susmano, JD, MBA and Brandon Vance, CPA

Effective October 7, 2023, through October 7, 2024, those affected by the conflict may seek an exemption from penalties and interest on income, withholding, sales, specialty, and excise taxes if they encounter difficulties in filing returns or making timely payments. To be eligible for relief, individuals or businesses must meet one of the following criteria:

  2. Any individual, business, sole proprietor, estate, or trust with books, records, or a tax preparer located within the covered area.
  3. Individuals who have suffered injury, loss of life, or have been taken hostage due to the conflict.
  4. Individuals associated with a recognized government or philanthropic organization providing aid within the covered area, such as relief workers.

Those in need of this relief can submit waiver requests electronically or by mail using the provided address on the return. For mailed requests, taxpayers must clearly mark “Israeli-Palestinian Conflict 2023” in red at the top of the return and include an explanation for their penalty and interest abatement request. The written request should provide a brief account of the reasons for the taxpayer’s inability to file or pay on time, along with their full name, account number (last four digits of the social security number for individuals), mailing address, and an estimated timeline for filing or paying taxes.

Illinois Grocery Tax Suspension

Per Illinois Public Act (P.A.) 102-0700, there will be a grocery tax suspension from July 1, 2022, through June 30, 2023. Currently, the tax on groceries in Illinois is 1%.

Items that are not included in the suspension and remain taxable include (but are not limited to), alcohol, food containing adult-use cannabis, candy, or food that has been prepared for immediate consumption. The statewide suspension of the grocery tax does not affect the Regional Transportation Authority and Metro-East Mass Transit District’s local tax on grocery items.

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 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 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, which 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.
