In a bank reconciliation, outstanding checks are subtracted from the bank statement balance, and they are not adjusted on your book balance at all. The bank shows money you have already committed to pay but that no one has cashed yet, so its number is too high until you take those checks back out.
Why the Subtraction Happens on the Bank Side
Your bank can only report transactions it has actually processed. If you wrote a check on the 20th and the payee hasn’t deposited it by the statement’s closing date, the bank’s ending balance still includes that money. You’ve committed the funds; the bank just doesn’t know it yet. Subtracting each uncleared check from the statement balance corrects that overstatement and gives you the amount truly available.
Article 4 of the Uniform Commercial Code governs how banks handle deposits and collections, including the timelines for clearing checks presented for payment.1Cornell Law School. U.C.C. – ARTICLE 4 – BANK DEPOSITS AND COLLECTIONS The gap between your records and the bank’s records is normal, not a sign of error. Subtracting outstanding checks simply bridges that gap.
Getting this wrong has a price. If you treat the bank’s inflated balance as spendable and the outstanding check clears later, you can trigger an overdraft fee (when the bank covers the transaction) or a non-sufficient funds fee (when it rejects the transaction).2FDIC.gov. Overdraft and Account Fees Fees can run up to about $35 per transaction at many banks and can stack within a single day.
Why the Book Balance Isn’t Adjusted for Outstanding Checks
Your check register or accounting software already recorded the check the moment you wrote it. Writing a $500 check drops your book balance by $500 that same day. Subtracting the $500 again during reconciliation would double-count the payment and make your records show less than you actually have.
Under the UCC, a check is a written order directing your bank to pay a fixed amount on demand.3Cornell Law School. U.C.C. Section 3-104 – NEGOTIABLE INSTRUMENT Signing and delivering the check authorizes the payment, and your books capture that obligation right away. No further adjustment on the book side is needed.
Deposits in Transit: The Companion Bank-Side Adjustment
Outstanding checks aren’t the only reconciling item on the bank’s side. Deposits in transit, meaning money you sent to the bank that hasn’t hit the statement yet, are added to the bank statement balance. A deposit made on the last day of the period may not clear by the closing date, so the bank’s number understates what you have.
The two adjustments push the same starting number in opposite directions:
- Outstanding checks are subtracted from the bank statement balance, because the bank still shows money you’ve committed to pay.
- Deposits in transit are added to the bank statement balance, because the bank hasn’t yet credited money you’ve already sent.
The result after both adjustments is your adjusted bank balance.
What Adjusts the Book Balance Instead
A different set of items adjusts your book balance. These are transactions the bank has already processed that you may not have entered yet:
- Bank service charges, such as monthly maintenance fees or per-check fees. Subtract from your book balance.
- NSF or returned checks, where a check you deposited from someone else bounced and the bank reversed the deposit. Subtract from your book balance.
- Interest earned that the bank credited but you haven’t recorded. Add to your book balance.
- Automatic payments or direct deposits the bank processed that you forgot to enter. Adjust in the appropriate direction.
After these corrections, your adjusted book balance should equal the adjusted bank balance.
How to Identify Outstanding Checks
Identifying outstanding checks takes a line-by-line comparison between your register and the bank statement. For each check, you need three pieces of information: the check number, the date written, and the exact dollar amount. Compare each entry in your register against the list of cleared checks, and mark off any check that appears on both.
Any check in your register that doesn’t appear on the statement is outstanding. The IRS describes it plainly: after accounting for all checks returned by the bank, those not marked in your checkbook are your outstanding checks.4Internal Revenue Service. Publication 583, Starting a Business and Keeping Records Total the uncleared checks. That total is what you subtract from the bank statement balance.
Watch the amounts closely. A check written for $250 but cleared for $205 could point to a bank error, a payee alteration, or a recording mistake. Catching those differences is one of the reasons the reconciliation exists in the first place.
A Full Reconciliation, in Order
Put together, the process runs like this:
- Start with the bank statement ending balance as of the closing date.
- Add deposits in transit that haven’t posted yet.
- Subtract the total of outstanding checks.
- The result is your adjusted bank balance.
- Start with your book balance, the running total in your register or software.
- Add unrecorded credits such as interest earned or direct deposits.
- Subtract unrecorded debits such as service charges, NSF fees, and automatic payments.
- The result is your adjusted book balance.
The two adjusted numbers should match. If they don’t, look for missed entries, transposed digits, or timing differences. The IRS recommends reconciling a checking account every month to keep records accurate and catch errors promptly.4Internal Revenue Service. Publication 583, Starting a Business and Keeping Records
Why Reconciling Monthly Protects You
Prompt reconciliation isn’t only good bookkeeping. Under the UCC, you have a duty to examine your bank statements with reasonable promptness and report unauthorized transactions. Failing to do so can cost you the right to hold the bank responsible after certain time limits pass.5Cornell Law School. U.C.C. Section 4-406 – Customer’s Duty to Discover and Report Unauthorized Signature or Alteration
For electronic transactions such as debit card charges and automatic withdrawals, federal Regulation E gives you 60 days from the date the bank sends a statement to notify the institution of an error.6eCFR. 12 CFR Section 205.11 – Procedures for Resolving Errors Reconciling as soon as the statement arrives keeps you well inside that window.
Two Things to Know About Old Outstanding Checks
An outstanding check doesn’t stay outstanding forever, and it also doesn’t automatically become void. Under the UCC, a bank has no obligation to pay a check, other than a certified check, that is presented more than six months after its date. But the bank may still choose to honor it in good faith.7Cornell Law School. U.C.C. Section 4-404 – Bank Not Obliged to Pay Check More Than Six Months Old Don’t treat an old outstanding check as safe to spend against.
Because an outstanding check hasn’t cleared, you can still stop payment on it. The UCC lets you order your bank to stop payment on any check drawn on your account, as long as the order reaches the bank in time to act on it.8Cornell Law School. U.C.C. Section 4-403 – Customer’s Right to Stop Payment Stopping payment doesn’t erase the underlying obligation to the payee; it only blocks the specific check.
