The annual fee might be a one-time charge on your credit card during a specific month of the year, or it could be divided and charged to your account monthly.
You may be able to avoid an annual fee by charging a certain amount on your credit card during the year. Contact your credit card issuer to find out how you can have your annual fee waived.
If your credit card issuer decides to impose a new annual fee or raise the current one, they're required by federal law to notify you 45 days before the new annual fee becomes effective. You have the option to reject the new annual fee, however, you'll have to close your credit card if you decide to opt-out. Think hard before opting-out because closing a credit card could hurt your credit score.
