Final answer:
Interest earned, fees, and checks written after the statement date can be in the checking register but not on the statement.
Step-by-step explanation:
One example of something that is in your checking register but cannot be on your statement is interest earned. Interest earned on your account is recorded in your checking register, but it is not included in your bank statement. Another example is fees charged by the bank. If you incurred any fees, they would be recorded in your checking register, but they may not be included in your statement. Lastly, a check you wrote after the statement date will be in your checking register but won't be on your statement.
