Book Balance vs. Bank Balance

Accounting 101: Part 8

Your ledger almost never matches your bank statement on a given day — and that’s normal. Here’s why, and what to do about it.

Two different balances

Book balance — what your ledger says, based on the date you recorded each transaction.
Bank balance — what the bank says, based on the date each transaction actually posted.

The gap between them is just timing: things get recorded before they clear.

Transaction date vs. post date

The transaction date is the date you enter in your ledger — the date you wrote the check, or the date a sale happened. The post date is the date the bank actually processes the money moving. They’re often days or weeks apart.

Walkthrough: write a check, it posts, you reconcile

Step 1: Write the check. You buy party supplies for the spring carnival and write a $75 check, dated June 25.

Account	Debit	Credit
Event Expenses	$75.00
Checking Account		$75.00

Your book balance drops by $75 on June 25 — the day you wrote it, not the day it clears.

Step 2: It cashes late. The vendor doesn’t deposit the check until a week later. Your bank balance doesn’t move until then.

Step 3: It posts. The bank’s statement shows the $75 clearing on July 3 — the post date.

Step 4: You reconcile. When you reconcile that account, you’re matching your June 25 ledger entry to the bank’s July 3 posting. Same transaction, two dates. Once matched, it’s cleared. Until then, it’s outstanding.

When it spans a fiscal year

If your fiscal year runs July 1–June 30 (see Part 4), that June 25 check belongs to the old year on your books — but it doesn’t clear the bank until July 3, into the new year. This happens constantly with checks written in the last week or two of a fiscal year.

The check itself doesn’t move — it stays recorded on June 25, in the year it was written. It just clears later. This is exactly why closing the fiscal year tells you to reconcile first: you want to know which of last year’s transactions are still sitting outstanding before you lock the books, not discover them months later when they finally clear.
