Income Taxes
Potential New Graduated Income Tax Rates One of Governor Pritzker’s primary campaign goals has been to implement a “Fair Tax for Illinois,” which would change Illinois’ tax structure from a flat income tax to a graduated income tax rate based on a taxpayer’s filing status and income. But, in addition to passing legislation amending the income tax rates, an amendment to the Illinois constitution is also required before this change can take effect.
During this legislative session, the following graduated income tax rates were passed and will be effective for taxable years beginning on or after January 1, 2021, only if Illinois voters pass the constitutional amendment that will be on the November 2020 election ballot.

The corporate income tax rate will also increase from 7% to 7.99% for a total corporate income tax rate (including personal property replacement tax) of 10.49%.
Income Taxation on Non-residents Working in Illinois Starting in 2020, non-residents who spend more than 30 days working in Illinois are deemed to have Illinois earned compensation and will be subject to Illinois income tax based on the total number of days worked in state.
In addition, employers with nonresident employees performing services in Illinois are required to maintain records of days worked by each nonresident employee or obtain a written statement from its nonresident employee with an estimate of the number of days reasonably expected to be performing services in state during the tax year.
Finally, Illinois residents may be allowed a credit for taxes paid to other states if they pay income taxes for days spent working in another state.
Modifications to Tax Cuts & Jobs Act (“TCJA”) Conformity Trusts and estates will be allowed a deduction equal to the amount of ‘excess business loss’ disallowed by IRC Sec. 461(l)(1)(B) for taxable years beginning after December 31, 2018 and before January 1, 2026.
Illinois enacted legislation to decouple from the federal deduction for 37.5% of foreign derived intangible income (“FDII”) from IRC Sec. 250.
