Westmont Tax and Accounting, from Ogden Avenue to Downtown

Auto row and the rest of the local economy

Choose DuPage credits Westmont with a business economy of more than $632 million a year. It says the Ogden Avenue dealership cluster alone produces more than $392 million a year in auto sales. The northern part of the village has office and research business parks. Downtown Westmont is developing as a transit-oriented district with restaurants, retail and mixed-use housing near the BNSF Metra station, which serves about 1,150 riders a day. Choose DuPage counts about 24,291 residents and 12,580 jobs, and it notes that O’Hare and Midway are each within 20 minutes and that seven major highways are nearby.

Dealerships and the suppliers, body shops and service businesses around them have staff, inventory and sales tax to manage. The services that fit:

• Payroll services, including commissioned and hourly staff
• Small business accounting and tax: monthly books plus the annual entity return
• Business tax preparation for partnerships and corporations

Sales tax: three rates in about a year

According to Illinois Department of Revenue rate files, Westmont’s general merchandise rate was 7.50% before July 1, 2025. It rose to 8.00% on that date and to 8.25% on August 1, 2026. Any seller of taxable retail goods needed to apply both increases, so check a sample of invoices from each period. Dealers and shops that own their lots should also plan for DuPage County’s 2027 general assessment, when every parcel gets a change of assessment notice.

New ventures downtown

If you are opening a restaurant or storefront in the new downtown development, choose an entity before you sign the lease so the lease, bank account and state registration all match. We can help with LLC and S corporation formation and the Illinois replacement tax that applies afterward: 1.5% for S corporations and partnerships, or 2.5% for C corporations.
