CPA in Batavia, IL: Tax, Payroll and Accounting

Batavia is a Fox River city of about 27,000 people, mostly in Kane County. Among employed residents, manufacturing is the second-largest sector, after education and health care. This page explains how Kane County property assessments and appeals work for a Batavia address, what the local employment mix suggests for tax planning and how a Naperville CPA firm can help.

Who lives and works here

The Census Bureau's American Community Survey (2020-2024 five-year estimates) counts about 27,200 residents with a median age of about 42. Median household income is about $120,000, about 77 percent of occupied homes are owner-occupied and about 57 percent of adults hold a bachelor's degree or higher. About 6 percent of residents were born outside the United States. Education and health care employs about a quarter of working residents, followed by manufacturing at about 16 percent, professional and administrative services and retail. About 24 percent work from home and about 8 percent are self-employed.

How a Kane County assessment works

Batavia's bill comes from the Kane County Treasurer. The assessment side is handled by the Kane County Assessment Office, in neighboring Geneva, working with township assessors. Each year the Assessment Office publishes a township's assessment changes in a local newspaper, and the notice states the final deadline for filing a complaint. In 2026, for example, the Batavia Township notice was published on July 30, with a filing deadline of August 31. Dates differ by township and year, so use your own notice and the county site.

The Kane County Board of Review reviews assessment complaints and requests for exemptions. Complaints are filed through an electronic evidence portal, with separate forms for residential and commercial property. An assessment complaint challenges the assessed value, not the tax rate, and evidence such as comparable sales usually decides the result. If you disagree with the Board of Review, one next step is the Illinois Property Tax Appeal Board. Part of Batavia lies in DuPage County, which uses a different system; see our DuPage County and Kane County pages.

Manufacturers and small shops

When one in six working residents is in manufacturing, equipment and inventory decisions matter. Purchases of equipment can qualify for Section 179 and bonus depreciation, subject to current-law limits we confirm each year. Manufacturers that develop new products or processes may qualify for the research credit. Inventory and cost of goods sold also need careful records; see inventory and cost of goods sold. Employers must register with IDES for unemployment insurance and follow the Paid Leave for All Workers Act, unless a local ordinance already applies.

How we can help

We prepare returns for Batavia households and professionals, help manufacturers and shops with equipment deductions, inventory records and payroll, and read IRS notices with you. Visit Naperville by appointment or work online, starting at the contact page.
