Chicago CPA and tax accountants

Illinois’ corporate income taxes are among the highest in the United States, with a 7% base rate and a 2.5% personal property replacement tax. Its sales taxes are also one of the most expensive in the country, starting at 10.25%, just 0.10% shy of the top spot.

That can be a lot to handle, especially in addition to Illinois’ individual state income taxes and the federal obligations every founder and small business owner faces.

Zeni’s tax accountant team helps Chicago businesses stay ahead of these challenges, continuously monitoring legislative changes to ensure compliance and identify opportunities. Our clients have saved more than $6.5 million in R&D tax credits alone.
