Wheaton Tax Preparation and Small Business Accounting

Two rate changes in one year

Illinois Department of Revenue rate files show Wheaton’s general merchandise sales tax rate went from 8.00% to 8.25% on July 1, 2026, and then to 8.50% on August 1, 2026. A downtown shop or restaurant that files monthly had two changes to make in its point-of-sale system within about five weeks. If your June, July and August returns used different rates, it is worth reconciling what was collected against what was reported before the year ends. Sales tax returns are filed with IDOR through MyTax Illinois, and an amended return corrects a month that was filed at the wrong rate.

Our bookkeeping services include matching sales tax collected to the filings each month, so an error like this shows up in the month it happens rather than during an audit.

Licensing a new business

The City of Wheaton publishes a business license application under “Starting a Business in Wheaton” on its website. If you are opening a storefront or office, check with City Hall on licensing before you open, and check the state side of registration with IDOR through MyTax Illinois. When you are forming the company itself, we can help with the LLC or S corporation decision and the federal and Illinois tax elections that go with it.

Households and commuters

Choose DuPage lists Wheaton at 53,453 residents, 27,792 jobs and a daytime population of 54,708. It also notes the city’s two train stations for commuting into Chicago, which is about 25 miles east. If your household combines a commuter’s W-2 income with rental property or side work, the return has more pieces to it. Our personal tax preparation covers the federal return and the Illinois return at the flat 4.95% rate, including Schedule C and rental schedules when you need them.
