The short version.
TechBrot provides QuickBooks cleanup for Illinois businesses — a Certified QuickBooks ProAdvisor brings a behind or broken file back to a CPA-ready standard. We fix the most common Illinois mess (single-rate sales tax instead of the correct 6.25% state + county and home-rule add-ons by location, up to 10.25% in Chicago), rebuild the books so Illinois net income is tracked cleanly for the Personal Property Replacement Tax (PPRT — even pass-throughs owe it), separate Chicago’s 15% lease/“cloud” tax from sales tax, and reconcile every account. Fixed-fee against a written scope (typically $1,500–$15,000+ by how far behind the file is). Independent firm — not affiliated with Intuit Inc.; we clean it up, your CPA files.
Illinois QuickBooks cleanup, in five questions.
What does Illinois QuickBooks cleanup fix?
Single-rate sales tax corrected to the right combined rate by jurisdiction (10.25% in Chicago), Illinois net income rebuilt so it’s tracked cleanly for the PPRT, Chicago’s 15% lease/cloud tax separated from sales tax, and every account reconciled back to a CPA-ready standard. We clean it up; your CPA files.
Why is my Illinois QuickBooks file wrong?
Usually one of three Illinois-specific problems: sales tax set to a single statewide rate instead of the correct combined rate by jurisdiction, Illinois net income never tracked cleanly for the PPRT, or Chicago’s lease/cloud tax lumped into sales tax or missed entirely — on top of unreconciled accounts.
How long does a cleanup take?
It depends on how far behind the file is — a few weeks for a single year, longer for multiple years. We scope it after a free file review so you know the timeline and fixed fee up front.
What does cleanup cost?
Fixed-fee against a written scope, typically $1,500–$15,000+ depending on how many months or years are behind and how broken the file is. Exact fee in writing within 3 business days.
What happens after cleanup?
Most Illinois businesses move into monthly bookkeeping with the same named ProAdvisor so the file never falls behind again. Cleanup-only is fine too.
From messy to CPA-ready, the Illinois way.
We fix the Illinois-specific things a generic cleanup misses — then reconcile the whole file back to clean.
Sales tax corrected
Single-rate sales tax replaced with the correct combined rate by jurisdiction (10.25% in Chicago), destination-based handling fixed, and prior periods reconciled back so the ST-1 ties.
Sales tax help →PPRT-ready books rebuilt
Illinois net income reconstructed and tracked cleanly so the Personal Property Replacement Tax is supportable at filing time — even for pass-throughs that owe it.
Replacement tax help →Chicago cloud tax separated
Chicago’s 15% lease/SaaS tax pulled out of the sales-tax bucket and tracked separately for providers with Chicago customers, so each ties on its own.
Sales tax help →Every account reconciled
Bank, credit-card, and loan accounts reconciled and miscategorized transactions corrected to a clean chart of accounts.
Reconciliation →Catch-up of months behind
Whether you’re a few months or a few years behind, we catch the file up to current and CPA-ready.
QuickBooks accountant →Stays clean after
Move into monthly bookkeeping with the same ProAdvisor so the file never falls behind again.
Monthly bookkeeping →Three Illinois problems a cleanup almost always finds.
Illinois files break in predictable ways — these three are the usual culprits, and all three are fixable.
The single-rate sales-tax mistake
The most common Illinois QuickBooks mess: sales tax set to one statewide rate instead of the correct 6.25% state + county and home-rule add-ons by location — up to 10.25% in Chicago (Cook County + city). Illinois is destination-based, so a single rate over- or under-collects and the ST-1 won’t tie. We correct it to the right combined rate by jurisdiction and reconcile prior periods back.
Net income never tracked cleanly
Illinois imposes an entity-level Personal Property Replacement Tax on net income — 2.5% for C-corps, 1.5% for S-corps, partnerships, and trusts — and even pass-throughs owe it. Messy files rarely track Illinois net income cleanly, so the PPRT isn’t supportable at filing time. Cleanup rebuilds the books so it is; your CPA computes and files.
Chicago’s cloud tax never separated
Illinois doesn’t tax SaaS — but Chicago does, through its Personal Property Lease Transaction Tax (the “cloud tax”), 15% as of January 2026. Messy files lump it into sales tax or miss it entirely. We separate Chicago’s lease/cloud tax from sales tax in QuickBooks so each ties on its own. It’s a City of Chicago tax (Dept of Finance), not a state tax.
What we do — and what we don’t.

Four steps from messy to handled.
Free file review
A Certified ProAdvisor reviews the file and finds how deep the cleanup goes — sales-tax jurisdictions, PPRT-relevant net income, Chicago cloud-tax exposure, reconciliation.
Written fixed-fee scope
A written scope and fixed fee within 3 business days, with the timeline and the Illinois-specific fixes listed.
Clean & reconcile
We correct sales tax by jurisdiction, rebuild Illinois net income for the PPRT, separate Chicago’s cloud tax, and reconcile every account.
CPA-ready handoff
A clean, current file handed to your CPA — or straight into monthly bookkeeping so it stays clean.
Automation handles the data entry. We handle the judgment.
An Illinois QuickBooks cleanup almost always finds the same three things — single-rate sales tax instead of the correct combined rate by jurisdiction, Illinois net income that was never tracked cleanly for the PPRT, and a Chicago lease/cloud tax that was lumped into sales tax or missed. None of them are filing problems; they’re bookkeeping problems, and all three are exactly what a Certified ProAdvisor fixes so your CPA’s filings are accurate.
Once the file is clean, the same named ProAdvisor keeps it that way in monthly bookkeeping — so you never need a second cleanup.
