Naperville CPA: Tax, Payroll and Accounting Services

CPA Tax Payroll and Accounting Corp is based at 1620 Pebblewood Ln in Naperville, Illinois 60563. If you are searching for a Naperville CPA for personal tax returns, a small business's books and payroll, or help with an IRS letter, this page explains what we do and the local tax details that shape the work: two counties, two property tax systems, and a city that levies several taxes of its own.

We meet clients at our Naperville office by appointment, and we also work fully remotely, so the same service reaches people in other suburbs and other states. Everything here is general information, not personal advice. Your own facts decide the answer.

Naperville by the numbers

The Census Bureau's American Community Survey (2020-2024 five-year estimates) gives a rough picture of who lives here. These are survey estimates with margins of error, so treat them as approximate.

The largest employment groups among residents are education and health care, professional and technical services, finance and real estate, and manufacturing. For households like these, the topics that tend to matter are equity compensation, retirement accounts, rental property, self-employment income on the side and, for many families, accounts and property in India. Nearby communities include Aurora, Bolingbrook, Lisle, Warrenville, Woodridge and Plainfield.

Property taxes: DuPage and Will

Illinois bills property tax a year behind, so the bills you pay in 2026 are for 2025. Which county sends yours depends on which side of the county line the parcel sits. In DuPage County the Treasurer collects, the Supervisor of Assessments publishes assessment changes, and township assessors set the starting values. The first two digits of a DuPage parcel number identify the township: 07 is Naperville Township and 08 is Lisle Township. Will County has its own Treasurer, Supervisor of Assessments and Board of Review.

For the 2025 taxes, DuPage mailed one bill on April 29, 2026, with installments due June 1 and September 1. Use your county's Treasurer site for each year's dates rather than relying on a past calendar. The DuPage Treasurer also notes that the general homestead exemption and the senior exemption are each listed at $8,000, so check that your bill shows the exemptions you qualify for.

An assessment appeal is not an appeal of the tax bill. It argues that the assessed value is too high compared with market value or with similar homes. In DuPage you file with the Board of Review within 30 days after your township's assessment roll is published, with evidence such as three or more comparable properties. Written decisions typically come the following March, and a further appeal can go to the Illinois Property Tax Appeal Board. Property taxes also feed the state and local tax deduction on a federal return. See our DuPage County and Will County pages for each county's offices.

The City of Naperville's own taxes

The City's Local and State Taxes page lists these taxes, which matter to restaurants, retailers, hotels and fuel sellers:

• A citywide food and beverage tax of 1 percent, plus an additional 0.75 percent in the downtown area
• A hotel and motel tax of 5.5 percent
• A local gas tax of 4 cents per gallon
• A home rule sales tax of 0.75 percent, collected by the State and passed to the City
• A 1 percent municipal grocery tax that replaced the State's 1 percent grocery tax, which ended on January 1, 2026

Businesses that owe the City's own taxes register with the Finance Department and file through the City's online portal. The State's general sales tax rate is 6.25 percent, but the rate at a specific address depends on location and period, so use the Tax Rate Finder on the Illinois Department of Revenue's MyTax Illinois site. Our sales and use tax service can help sort out filing. City rates can change, so confirm them on the City's page before relying on them.

Illinois rules that affect Naperville filers

• Income tax. Illinois taxes individuals at a flat 4.95 percent of net income. Residents can subtract federally taxed Social Security and certain retirement income on their Illinois return. See our Illinois guide.
• Pass-through entities. Partnerships and S corporations pay the Personal Property Replacement Tax, listed by the Department at 1.5 percent of net income, and may elect to pay a 4.95 percent entity-level tax on the entity return. The election cannot be undone after the extended due date. See S corporation taxes.
• Employers. Every business with Illinois employees registers with IDES and files unemployment insurance reports each quarter. The Paid Leave for All Workers Act, in effect since January 1, 2024, gives most employees up to 40 hours of paid leave a year. Employers with staff in Chicago or Cook County should also check those local ordinances.
