"This firm is absolutely fantastic! I had income from both Illinois as well as Massachusetts and my taxes were more complex this year than ever before. I also have a four person LLC for window and door installation. This company helped me get both my books together as well as my tax returns. I have been using them for four years now and have been very happy ever since." -Rocky Millwood, Google Review

Chicago Lease Tax and IDOR Replacement Tax

Chicago’s Personal Property Lease Transaction Tax is a city-level levy charged at 15 percent of the rental or lease price on personal property used inside city limits. A clean IDOR return tells the city nothing about whether the lease transaction tax was filed. Those are two separate agencies on two separate penalty calendars.

Illinois Replacement Tax and Apportionment

Illinois replacement tax applies separately, at a rate distinct from the flat income tax. Transportation, logistics, and manufacturing operators add apportionment and sales-and-use reconciliation to that stack. Our bookkeeping services in Chicago feed the same source numbers into each of those calculations, no filing draws from a different set of books. From one engagement, we cover: City lease compliance IDOR replacement tax Pass-through entity elections City licensing

Loop Partners, RSU Holders and Illinois Schedule CR

Illinois does not allow residents to subtract out-of-state income. The state taxes residents at a flat 4.95 percent, with no graduated brackets and no deduction for federal income tax paid. Nonresidents cannot use Schedule CR at all. Common profiles we handle include: Loop finance partners Fulton Market founders carrying RSUs Consultants billing across state lines

Does Chicago's Personal Property Lease Transaction Tax apply to our SaaS subscriptions?

Yes. Cloud software used inside Chicago city limits qualifies as personal property under the Municipal Code. The rate is 15 percent of the lease or rental price, and vendor location does not change it. This return files with the city, not IDOR, on its own separate deadline. We manage that filing alongside the Illinois state return so neither is missed.

Can Chicago residents subtract New York income from their Illinois return?

No. Illinois Schedule CR provides a credit for qualifying tax paid to another state, not a subtraction of the income itself. The credit applies only to tax paid on income earned while you were an Illinois resident. Nonresidents cannot use Schedule CR at any income level. Dimov Tax reconciles both the Illinois and New York returns before either is filed.

Does Illinois disallow the property tax credit above a certain income?

Federal AGI above $250,000 triggers the disallowance. That threshold also drops the exemption allowance to zero. Both limitations hit the same return, on the same filing, with no separate notice from IDOR. A Chicago CPA running the full Illinois calculation catches both before the return goes out.

What Chicago obligations apply to employees on a Delaware-registered payroll?

City licensing applies to businesses operating in Chicago regardless of where they are registered. Chicago payroll services covering in-city employees must comply with Illinois withholding and unemployment tax requirements from the first paycheck. In-city employee hours also factor into the business license fee tier. We review registration, licensing category, and withholding setup at the start of every engagement.

When does a Chicago business dispute or IRS audit require forensic accounting?

Forensic accounting in Chicago applies when financial records are incomplete, a business valuation is contested, or unreported income is at issue in an audit. IRS examinations involving reconstructed financials or alleged fraud follow a different process than a standard correspondence audit. We assign a licensed CPA or Enrolled Agent to that work from the first call. A junior associate does not touch the file.
