How to Prepare for Tax Season Using illico Book

May 2026 · 6 min read

Tax season is stressful mainly for one reason: most business owners don't look at their numbers until they're forced to. Here's how to use illico Book to walk into tax season with everything already organized, instead of spending a weekend reconstructing a year of transactions.

Step 1: Make Sure Every Transaction Is Categorized

Your P&L statement is only as accurate as the categories behind it. Before anything else, go through your transaction list and confirm nothing is sitting in "uncategorized." illico Book flags uncategorized transactions automatically, so this is usually a quick pass rather than a deep audit.

Step 2: Reconcile Every Account

Check that your bank accounts, mobile money wallets, and cash balances in illico Book match your actual statements for the full tax year. If you've been reconciling weekly, this step takes minutes. If you haven't, now's the time — before your accountant does it for you, at a higher hourly rate.

Step 3: Generate Your P&L Statement

Once your accounts are reconciled and categorized, illico Book's P&L Statement gives you a full income and expense breakdown for the year in one click. This is the document most accountants ask for first, and it's the foundation for your tax filing.

Step 4: Pull Your Tax Report

illico Book's dedicated Tax Report goes a step further than the P&L — it organizes your deductible expenses into the categories your tax preparer actually needs, so nothing gets missed and nothing needs to be re-sorted by hand.

Step 5: Export and Share With Your Accountant

Export your reports directly from illico Book and send them to your accountant — or, if you work with illico AS & TC, LLC, we can pull them directly with your permission. Either way, what used to take a full weekend of digging through receipts becomes a same-day handoff.

A Habit Worth Building

The businesses that find tax season painless are the ones that treat their books as a living document all year, not a project that starts in March. Checking your P&L monthly, reconciling weekly, and categorizing transactions as they happen means tax season is just a formality — not a fire drill.
