Illinois R&D Tax Credits

Find out if you qualify for R&D tax credits in Illinois and recharge your business.

Illinois provides a research and development (R&D) tax credit. Until January 1st, 2027, an R&D credit is allowed against income tax for research activities in Illinois state. The credit is equal to 6.5% of qualifying expenditures over a comparative base amount. The base amount is the average of the prior three years of QREs attributed to Illinois. Excess credits not utilized in a tax year can be carried forward up to five years.

Businesses or taxpayers cannot take this credit for the following kinds of activities:

• research conducted after the beginning of commercial production;

• research adapting an existing product or process to a particular customer’s need;

• duplication of an existing product or process;

• surveys or studies;

• research relating to certain internal-use computer software;

• research conducted outside Illinois;

• research in the "soft sciences", social sciences, arts, or humanities;

• research funded by another person (or government entity).

Illinois’ biggest R&D sectors are pharmaceuticals, machinery, and not surprisingly, agricultural. The state also sees innovations in the banking and insurance sectors.
