Companies and households

Choose DuPage notes that the village markets expedited staff assistance, high-capacity utilities and infrastructure investment to companies choosing a site. For a new company here, the first decisions are entity type and registration. We handle LLC and S corporation formation and the tax elections that go with it. Illinois treats these entities differently: S corporations and partnerships pay 1.5% replacement tax on net income, and C corporations pay 2.5% plus the 7% corporate income tax. After formation, business tax preparation covers the annual federal and Illinois entity returns.

For Lisle households, personal tax preparation covers the federal return and Illinois’ 4.95% flat-rate return. That includes Schedule C for side businesses and K-1 income from any company you own.
