Illinois IRS collection standards for 2026
Published monthly limits by household size, effective 2026-06-29.
Introduction
This reference covers 102 county-level areas in Illinois using the verified 2026 IRS collection financial standards. Find your county or county equivalent, then use the column for your household size. The last housing column is for five or more people. These figures support a collection financial analysis; they do not show how much an individual household must pay the IRS.
Housing and utilities are one combined category. For the normal local-standard treatment, compare actual eligible spending with the applicable limit. Documented necessary costs can require individual consideration. Food, clothing and related national allowances and age-based healthcare amounts are listed on the standards hub.

DIY and when to get help
You can use this reference and the linked IRS tables without hiring anyone. Seek help if your household shares expenses with someone who does not owe the tax, your necessary costs exceed a normal limit, or the correct county or metropolitan area is unclear.
Questions you may have
Is there one housing allowance for all of Illinois?
No. Housing and utilities figures vary by county-level area and household-size band. Confirm the row for where you live and use the current effective period. Official state table
Do I automatically get the full housing amount?
Ordinarily the local-standard rule compares actual eligible expenses with the limit. Documented exceptions require IRS consideration. The table alone does not establish the amount allowed in your case. IRS rules
Can I use this page to calculate an offer?
It provides only part of the information. An offer illustration also needs income, other expenses, asset treatments and the application conditions. Use the OIC worksheet and read its limits.
