Why Illinois books need a Illinois calendar
Clean books are only useful if they line up with what the state expects. Illinois has a 6.25% state sales tax (about 8.96% combined with local rates), a flat 4.95% personal income tax and an annual report of $75, due Annual, anniversary month. We build the chart of accounts and the month-end checklist around those facts, so the numbers are ready for whichever return comes next.

|---|---|---|
| Personal income tax | A flat 4.95% personal income tax | Flat rate on taxable income (2025 table) |

| Sales tax | A 6.25% state sales tax (about 8.96% combined with local rates) | Combined figure is the population-weighted average with local rates (2026 table) |

What we watch for Illinois clients
Illinois taxes corporations at a combined 9.5% once the replacement tax is included, and pass-through entities pay a 1.5% replacement tax on their own income. LLCs file an annual report each year on the anniversary month with a $75 fee.
Sales tax is the usual trouble spot. Illinois's a 6.25% state sales tax (about 8.96% combined with local rates) has to be tracked as a liability, not income, and remote sellers cross Illinois nexus faster than they expect. Owner draws, loans between related entities and uncategorised transactions are the other three things we clean up most often. Nobody did anything wrong; there was simply never a monthly close.

Illinois questions people ask first
Do you handle Illinois sales tax?
Yes. We track Illinois sales tax as a liability in the books, reconcile it to what was collected, and file the returns as an add-on at $50 per state per month.
Do I keep my own QuickBooks or Xero subscription?
Yes. You own the file; we work inside it with accountant-level access, so you can see everything at any time.
Who does the work?
A dedicated bookkeeper on our Mumbai team does the daily and monthly work. A CPA in the team reviews the month-end close before reports go out.
Can you fix a messy file?
Yes. Clean-up and catch-up are quoted as a fixed project first, then you move to a monthly plan. Typical turnaround is two to four weeks.

That is the point of the monthly close. Year-end financials are tax-ready, and we can prepare the business return itself from $99.
