Illinois monthly bookkeeping, in five questions.
What is monthly bookkeeping in Illinois?
A real close of your books every month — reconciliation, clean categorization, sales tax reconciled by jurisdiction, Illinois net income kept current for the PPRT, Chicago’s cloud tax handled, and CPA-ready statements, in your own QuickBooks file, by the same ProAdvisor. We do the books; your CPA files.
Why does a monthly close matter in Illinois?
Because the combined sales tax, the PPRT (computed from Illinois net income), and Chicago’s cloud tax are all computed from your books — a monthly close keeps those figures accurate all year so filing is a non-event for your CPA.
Do you work in my own QuickBooks file?
Yes — your file, your data, in QuickBooks Online or hosted Desktop, with a named ProAdvisor on the same file every month.
What does it cost?
Fixed-fee against a written scope, never hourly: $400–$2,500+/mo by volume and accounts; one-time cleanup before monthly cadence $1,500–$15,000+. Exact fee in writing within 3 business days.
Do you file Illinois taxes?
No — TechBrot keeps the books CPA-ready and coordinates with your CPA, who files. Independent firm; not affiliated with Intuit Inc.

Fractional CFO →Three Illinois facts a monthly close keeps clean.
Closing every month keeps the sales tax, the PPRT, and Chicago’s cloud tax accurate year-round — not reconstructed under deadline.
A close every month, not a scramble at filing
Monthly bookkeeping means the books are reconciled and closed each month — so the combined sales tax, the PPRT net income, and Chicago’s cloud-tax figures are right all year, not reconstructed at filing time.
Sales tax reconciled every month, by jurisdiction
Illinois combined sales tax (6.25% state to 10.25% in Chicago) is reconciled monthly so each IDOR ST-1 ties and nothing is owed by surprise.
Illinois net income kept current
The Personal Property Replacement Tax is computed from Illinois net income — a monthly close keeps that figure current and supportable, for C-corps (2.5%) and pass-throughs (1.5%) alike. Your CPA computes and files.

Automation handles the data entry. We handle the judgment.
The case for a monthly close in Illinois is simple: the combined sales tax, the PPRT, and Chicago’s cloud tax are only as accurate as the books behind them. Close every month and all of it stays right — close once a year and you’re reconstructing the Illinois net income and the Chicago exposure under deadline.
Start with a reliable monthly close, then extend — when you’re ready — into fractional-CFO advisory including PPRT/PTE planning, in coordination with your CPA.
