The short version.
TechBrot keeps the figures behind Illinois’s entity-level taxes clean in your QuickBooks file. Illinois has a flat 4.95% personal income tax, but the entity layer is what trips owners up: the Personal Property Replacement Tax (PPRT) is an entity-level tax on net income — 2.5% for C-corps, 1.5% for S-corps, partnerships, and trusts, owed even by pass-throughs; a C-corp’s combined rate is 9.5% (7% corporate + 2.5% PPRT); and the permanent PTE election lets S-corps and partnerships pay a 4.95% entity-level tax as a SALT-cap workaround (made permanent by SB 1911 in December 2025). All of it is computed from Illinois net income, so we keep that figure clean and supportable; the computation, the PTE decision, and filing stay with the IDOR’s rules and your CPA.

Illinois replacement tax (PPRT) & PTE, in five questions.
What is the Illinois Personal Property Replacement Tax (PPRT)?
An Illinois entity-level tax on net income that replaced the personal property tax abolished in 1970 — 2.5% for C-corporations, 1.5% for S-corporations, partnerships, and trusts. Critically, pass-throughs owe the 1.5% at the entity level even though income flows to owners. We track Illinois net income cleanly so the PPRT is supportable; your CPA computes and files.
Why is an Illinois C-corp’s rate 9.5%?
A C-corporation pays the 7% Illinois corporate income tax plus the 2.5% PPRT for a combined 9.5% — among the highest corporate rates in the nation. S-corps and partnerships avoid the 7% and pay only the 1.5% PPRT, which makes entity choice consequential for Illinois businesses. We keep the figures clean; your CPA computes.
What is the Illinois PTE election?
An optional Pass-Through Entity tax letting S-corps and partnerships pay a 4.95% Illinois tax at the entity level — a workaround to the federal SALT deduction cap. It was made permanent by SB 1911 in December 2025. Whether to elect is a recurring planning decision; the bookkeeping must support the entity-level payment and the owner-level credit. We keep the books; your CPA advises and elects.
What does TechBrot do for these taxes?
We keep Illinois net income clean and reconciled in QuickBooks — the figure all three taxes are computed from — so your CPA can compute the PPRT, model the PTE election, and file accurately. We don’t compute the liability, advise on or make the PTE election, or file the returns.
Do you file my PPRT or PTE returns?
No — TechBrot keeps the books CPA-ready and coordinates with your CPA, who computes and files the PPRT, makes the PTE election, and files the income tax. We are an independent Certified QuickBooks ProAdvisor firm, not affiliated with Intuit Inc. or the Department, and we do not represent clients.

Illinois’s flat income tax is the simple part — the PPRT, the C-corp combined rate, and the PTE election are where the books matter.
The Personal Property Replacement Tax
An Illinois entity-level tax on net income that replaced the old personal property tax — 2.5% for C-corps, 1.5% for S-corps, partnerships, and trusts. Pass-throughs owe the 1.5% at the entity level even though income flows to owners — an Illinois-specific obligation most states don’t impose. We track Illinois net income; your CPA computes and files.
The 9.5% combined C-corp rate
An Illinois C-corporation faces a combined 9.5% — the 7% corporate income tax plus the 2.5% PPRT — among the highest in the nation. S-corps and partnerships avoid the 7% and pay only the 1.5% PPRT, so entity choice is consequential. We keep the figures clean; your CPA computes.
The permanent PTE election (4.95%)
Illinois offers a Pass-Through Entity tax election — S-corps and partnerships pay a 4.95% entity-level tax as a federal SALT-cap workaround — made permanent by SB 1911 in December 2025. Whether to elect is a key planning call; we keep the books so your CPA can model and support it.
