Accounting for Glendale Heights’ Commercial and Industrial Businesses

Growth led by business, not only housing

Choose DuPage says Glendale Heights grew from 104 residents in 1958 to about 32,864. It describes the village’s growth over the past decade as mainly commercial and industrial, and it identifies the North Avenue corridor as a focus area with infrastructure improvements already in place. Total employment in the village is about 19,147 and the daytime population is about 28,211. Choose DuPage notes that the major commercial centers sit at the edges of the village, where they serve shoppers from surrounding communities as well as residents.

For industrial and service businesses, the accounting questions tend to be about staff and structure rather than retail sales. That is why the services that fit Glendale Heights owners are weighted toward the back office:

• Payroll services, including Illinois withholding and the quarterly federal filings for shift and hourly workers
• Business tax preparation for corporations and partnerships, including Illinois replacement tax (1.5% for S corporations and partnerships, 2.5% for C corporations)
• LLC and S corporation formation for a new shop, or for an existing sole proprietorship that has outgrown Schedule C

Sales tax: 8.25% to 8.75% in eight months

IDOR rate files show Glendale Heights’ general merchandise rate rose from 8.25% to 8.50% on January 1, 2026, and to 8.75% on August 1, 2026. Businesses that sell taxable goods at retail, even as a small share of revenue, needed to apply both changes. Businesses that sell only to other businesses for resale should keep resale certificates on file.

Owners’ personal returns

When a business is an LLC taxed as an S corporation or a partnership, its income flows to the owner’s personal return. There it is taxed at Illinois’ flat 4.95% rate plus federal tax. We prepare the personal return together with the business return so the numbers match. If the business does not withhold tax from what it pays you, plan quarterly estimated payments to both the IRS and Illinois.
