CPA in Downers Grove, IL: Tax, Payroll and Accounting

Downers Grove is an established DuPage County village northeast of Naperville, with a relatively older and more self-employed population than many nearby suburbs. That shapes the tax questions that come up: how Illinois treats retirement income, which senior property tax breaks exist in DuPage, and how professionals who work for themselves handle estimated payments. This page covers those topics and the local details we think matter.

A mature, professional community

The Census Bureau's American Community Survey (2020-2024 five-year estimates) counts about 50,000 residents with a median age of about 44, older than in many nearby suburbs. Median household income is about $115,000, about 58 percent of adults hold a bachelor's degree or higher, and about 75 percent of occupied homes are owner-occupied. About 10 percent of residents were born outside the United States. Among employed residents, education and health care, professional and technical services, finance and real estate, and retail are the largest groups, and about 24 percent work from home. About 11.5 percent of working residents are self-employed, a higher share than in most of the nearby suburbs we cover.

Retirement income and senior property tax relief

Illinois has its own rules for retirement income. Residents can subtract Social Security benefits and certain retirement income that were taxed federally, which the Illinois Department of Revenue explains on its retirement income page. The rules depend on the type of plan and where the amount appears on the federal return, so read the guidance or ask a professional. See Social Security benefits taxation and Roth conversions.

On the property tax side, the DuPage Treasurer's office lists a senior citizens' homestead exemption, a senior assessment freeze homestead exemption and a senior real estate tax deferral program. The Treasurer says it hears each year from eligible seniors who have not applied for the senior exemption, so confirm that your bill shows it. The Supervisor of Assessments administers these programs, and the exemptions have eligibility rules, so check with that office before assuming you qualify. Our seniors and retirees page has a broader overview, and retirees with accounts in India can see NRE, NRO and FCNR accounts.

Township assessor and appeals

DuPage assigns township numbers by parcel prefix. Downers Grove Township uses 09 and 10, and its assessor's office is on Prince Street in Downers Grove. Start there if you question your assessed value. If you still disagree, file with the DuPage County Board of Review within the statutory 30-day window after your township's assessment roll is published, with comparable-property evidence. The appeal is about assessed value, not the tax bill amount. See salt deduction and property taxes for how property tax is deducted federally.

Self-employed professionals

With one in nine working residents self-employed, estimated taxes and entity choice are common topics. A sole proprietor files Schedule C and may owe self-employment tax; an S corporation owner must pay reasonable compensation through payroll. See Schedule C for sole proprietors, reasonable compensation for S corporation owners and estimated taxes. Illinois S corporations and partnerships also pay replacement tax and may elect an entity-level tax, described in our Illinois guide.
