For adults, the cost for a passport book will be $145. The fee for children 16 and younger will be $115. It's an increase of only $10, but that's on top of a fee that already was pretty steep—those who live in the United Kingdom pay roughly 30% less for their passports.
Passport cards, which are used for land and sea border crossings into Mexico, Canada, Bermuda, and the Caribbean, are also going up to $65 adults, $45 kids. The increase is not charged to those applying by mail.
The takeaway: Don't dilly-dally until April. Now is the time to get a new passport or to get your old one renewed.
