To get reimbursed for the TSA PreCheck fee with a Chase Sapphire card, you must hold the Chase Sapphire Reserve®; the Chase Sapphire Preferred® does not offer this benefit. If you have the Reserve card, simply use it to pay the $78–$85 application fee at your in-person appointment or online. After the charge posts to your statement, Chase will automatically issue a statement credit for the full amount. This benefit is available once every four years. You do not need to "activate" the benefit beforehand, as the system identifies the specific merchant code from the TSA or Global Entry. Note that the credit also applies to Global Entry ($120) and NEXUS ($120); if you travel internationally, it is better to apply for Global Entry, as it includes TSA PreCheck, and the Reserve card will cover the higher fee just the same.
