When you have a checking account you must balance deposits with the checks you write to make sure your account doesn't go into the red. Careful planning and record-keeping should keep your account from dipping into negative numbers. It’s wise to avoid a negative balance because your bank will penalize you for these financial blunders with fees and penalties.
If the bank covers your overdraft check you usually face some type of penalty. Overdraft fees are usually what you pay for the bank's covering your check. Expect a fee for each check your bank pays. Your bank could also charge a separate service charge for every day your checking account has a negative balance. If you set up an overdraft protection, your bank might move money between accounts to cover overdrafts or you might create a reserve account to do so. Overdraft protection generally involves a fee for each transfer.
Banks have varying policies about penalty fees for returning checks unpaid. Some return a check for insufficient funds and charge you a fee. When your bank returns your unpaid check to whomever it was you tried to pay, that company will probably charge you a returned check penalty fee on top of what the bank charges you. That can get expensive very quickly.
If you have a debit card connected to your checking account and try to use it after your account goes into overdraft, your bank will decline your transaction unless you have overdraft protection. A declined transaction could be an embarrassing result of a negative account balance and you'll probably be charged for the privilege.
Bank policies generally allow for an accidental lapse in calculations and the occasional overdraft. A pattern of overdrafts is cause for concern, though. If overdrafts don’t stop and reach a specific point, the bank might decide to close your account. Each bank has an individual threshold for closing an account, so it’s wise to find out about your own bank’s policies. If the bank closes your account because of account abuse, it might report that fact to the major credit reporting bureaus. If that happens, you might have trouble opening another checking account.
