Illinois Income Tax Act

On June 4, Illinois Governor Bruce Rauner signed into law the state’s fiscal year (FY) 2019 budget implementation bill, Public Act 100-0587 (the Act). The Act makes a significant change to the Illinois sales/use tax nexus standard by adopting an “economic nexus” standard for a sales/use tax collection obligation. The economic nexus language was added to the budget bill one day before it was passed by the General Assembly. The standard is contrary to the physical presence nexus standard established by the United States Supreme Court in Quill Corp. v. North Dakota, 504 US 298 (1992), the validity of which is currently pending before the Court in South Dakota v. Wayfair, Docket 17-494. The Court is expected to rule on Wayfair by the end of this month (see here for our prior coverage of the Wayfair case).

The Act amends Section 2 of the Use Tax Act to impose a tax collection and remission obligation on an out-of-state retailer making sales of tangible personal property to Illinois customers if the retailer’s gross receipts from sales to Illinois customers are at least $100,000 or the retailer has at least 200 separate sales transactions with Illinois customers. Similarly, it would amend Section 2 of the Service Use Tax Act with respect to out-of-state sellers making sales of services to Illinois customers. These changes mirror the economic nexus standard adopted by South Dakota. See SD Codified Laws § 10-64-2.

In the wake of Wayfair, other states have adopted similar nexus provisions. See, e.g., Conn. SB 417, Ga. HB 61, Haw. HB 2514, Iowa SF 2417, provisions enacted in 2018. By enacting the statute without an escape clause, Illinois, like other states, has put a law on the books that directly conflicts with Quill, and which will be ripe for constitutional challenge if the US Supreme Court affirms the South Dakota Supreme Court’s ruling that the South Dakota statute is unconstitutional.

The Act also amended Section 223 of the Illinois Income Tax Act to extend the tax credit for for-profit hospitals (equal to the lesser of property taxes paid or the cost of charity care provided) to tax years ending on or before December 31, 2022.

The Act made no changes in response to the federal tax reform bill. In particular the General Assembly did not enact Senate Bill 3152 (proposing to add-back the new federal deduction for foreign-derived intangible income (FDII); see here for our prior coverage). The General Assembly also did not enact either of the pending bills (HB 4237 and 4563) proposing to work around the federal $10,000 limitation on the deductibility of state and local taxes by establishing funds/foundations to which taxpayers could make contributions in exchange for tax credits.

The 2017 federal tax reform bill, known as the Tax Cuts and Jobs Act (Act), made a number of significant changes to the law, particularly to the international tax provisions of the Internal Revenue Code (IRC). Last month, Illinois joined the growing number of states responding to the Act by proposing legislation purporting to add-back the new federal deduction for foreign-derived intangible income (FDII). The FDII deduction, enacted in sub-part (a)(1)(A) of new IRC section 250, allows US corporate taxpayers a deduction in the amount of 37.5 percent of income earned from the sale of property to a person outside of the US for use outside of the US or the provision of services to a person outside of the US or with respect to property not located in the US. (For tax years beginning 2026, the deduction is reduced to 21.875 percent.)

Senate Bill (SB) 3152 (linked here) proposes an amendment to Section 203(b)(2) of the Illinois Income Tax Act (IITA) that would add back to taxable income the amount of a corporate taxpayer’s FDII deduction allowed under the IRC. Absent this amendment, the FDII deduction likely automatically would be included in Illinois’ corporate tax base: Illinois is a “rolling” conformity state (IITA section 1501(a)(11)), and the FDII deduction is a “special deduction” under the IRC which is incorporated in Illinois’ starting point for taxable income (IITA section 203(b)(1), (e) (For corporations IITA imposed on “taxable income” as defined under the IRC); IRC section 63 (“taxable income” includes “special deductions”)).

SB 3152 has been assigned to the Senate Revenue committee for review. It remains to be seen how, if at all, Illinois will respond to other changes enacted by the federal Act, particularly with respect to the other new international tax provisions, including those related to the deferred foreign earnings transition tax and global intangible low-taxed income, which include both additions and deductions at the federal level.

Last year, Illinois enacted a mid-year income tax rate increase. Effective July 1, 2017, Illinois increased the income tax rate for individuals, trusts and estates from 3.75 percent to 4.95 percent, and for corporations from 5.25 percent to 7 percent. The Illinois Personal Property Replacement Tax (imposed on corporations, partnerships, trusts, S corporations and public utilities at various rates) was not changed.

As we previously reported, the Illinois Income Tax Act contains a number of provisions intended to resolve questions regarding how income should be allocated between the two income tax rates applicable in 2017. 35 ILCS 5/202.5(a). The default rule is a proration based on the number of days in each period (181/184). For taxpayers choosing this method, the Department of Revenue (Department) has recommended the use of a blended tax rate to calculate tax liability. A schedule of blended rates is included in the Department’s instructions for the 2017 returns. The blended rate is 4.3549 percent for calendar year individual taxpayers and 6.1322 percent for calendar year C corporation taxpayers.

Yesterday afternoon, after months of wrangling and a marathon 4th of July weekend session, the Illinois House of Representatives voted to override Governor Bruce Rauner’s veto of Senate Bill (SB) 9, the revenue bill supporting the State’s Fiscal Year (FY) 2017-2018 Budget. The vote ended Illinois’ two year budget impasse and may avoid a threatened downgrade of Illinois bonds to junk status. The key tax components of the bill as enacted Public Act 100-0022 (Act) are as follows:

Income Tax

Rate increase. Income tax rates are increased, effective July 1, 2017, to 4.95 percent for individuals, trusts and estates, and 7 percent for corporations.

Income allocation. The Act contains a number of provisions intended to resolve questions regarding how income should be allocated between the two rates in effect for 2017.

  • Illinois Income Tax Act (IITA) 5/202.5(a) provides a default rule, a proration based on the days in each period (181/184), for purposes of allocating income between pre-July 1 segments and periods after the end of June when rates increase. Alternatively, IITA 5/202.5(b) provides that a taxpayer may elect to determine net income on a specific accounting basis for the two portions of their taxable year, from the beginning of the taxable year through the last day of the apportionment period, and from the first day of the next apportionment period through the end of the taxable year.
