Finding Trial Balance Errors
When preparing a trial
balance, the total debits
must equal the total credits.
Don't be discouraged if they don't. Bookkeeping errors happen. Just think of the
trial balance as a tool to find the errors. Use the following steps as a guide
to track down the error or errors.
- Be sure the numbers on your trial balance are the same numbers shown in
your general
ledger. Check to see if you properly classified amounts as debits or
credits on your trial balance.
- Go back to your journals (sales
and cash receipts journal, cash
disbursements journal, and general
journal). Check that the journal totals were properly posted
to the general ledger. Were the correct amounts posted? Were they properly
classified as debits or credits?
- Go back to each journal again. Look at the totals that were posted to the
general ledger. Do total debits equal total credits in each journal?
- Go back to each journal again. Did you foot
each column on each page of the journal? Did you carry forward all column
totals to the next page? Did all the items entered in the
"miscellaneous" column get posted to the general ledger?
- Is the difference divisible by nine? If so, it could be a simple
transposition error. For example, writing down 540 instead of 450 results in
a difference of 90. Writing down 26 instead of 62 results in a difference of
36. Notice that both of these differences are divisible by nine. If the
difference between debits and credits is divisible by nine, go back to the
journals, looking for the error. Knowing that it may be the result of
transposed numbers should help you find it.
- Is the difference between debits and credits 1, 100, 1,000, 10,000, etc.?
If so, it is probably an addition or subtraction error.
- Divide the difference by two. Is the resulting number shown on your trial
balance? If so, check to see if you have incorrectly classified the amount
as a debit or credit.
