Here's a new way the federal government might encourage you to get your paperwork in order: an $18 charge every time you forget it. The Transportation Security Administration has proposed a fee for travelers who show up at airport security without a REAL ID or other approved identification. Think of it as a forgetfulness tax, except it's funding a biometric verification system instead of going into some general revenue bucket.

REAL ID Is No Longer Optional

The REAL ID requirement has been looming since 2005, but after nearly two decades of delays, it finally went into effect in May 2025. If your state-issued driver's license or ID card doesn't have that little star in the corner indicating REAL ID compliance, it won't get you through TSA checkpoints anymore.

You can still use alternatives like a U.S. passport, passport card, or trusted traveler card. But if you show up empty-handed or with the wrong documents, you'll need to go through the TSA's identity-verification process. The Department of Homeland Security describes the current system as "time and resource intensive," which is government-speak for "this takes forever and we'd like to fix it."

What You're Actually Paying For

Under the proposed rule, travelers without acceptable ID would be directed to a new biometric kiosk at the checkpoint. The kiosk would collect biographic or biometric information and attempt to match it against the traveler's Secure Flight screening result. If everything checks out, you get to proceed to the secure area where gates, concourses, and overpriced airport sandwiches await.

The $18 fee is meant to cover the infrastructure behind this system. DHS says the money would support software development, data systems, identity-validation tools, program management, customer service, and general operations. Essentially, biometric verification doesn't run on goodwill and outdated Excel spreadsheets, so someone has to pay for it.

There's a catch, though: the fee is non-refundable. Even if TSA can't verify your identity or denies you access to the secure area, you're still out $18. On the bright side, once you pay the fee, it remains valid for 10 days. So if you're still scrambling to get proper ID sorted out, you can at least use the verification system for additional flights during that window without paying again.

How the Verification Process Works

Being directed to the kiosk doesn't guarantee smooth sailing. DHS notes that some travelers may still face delays, additional screening, or even denial of entry into the secure area. And if you decline to participate in the identity-verification process or TSA simply can't verify who you are, you won't be allowed through security. No verification, no flight.

The system is designed to be faster and more efficient than the current manual process, which presumably involves a lot of phone calls and cross-referencing. Whether paying $18 to use a kiosk feels like progress or just another airport inconvenience probably depends on how badly you need to catch your flight.

What Counts as Acceptable ID

To avoid the fee altogether, travelers need to bring one of TSA's approved forms of identification. The list includes REAL ID-compliant driver's licenses or state ID cards, U.S. passports and passport cards, DHS trusted traveler cards like Global Entry, NEXUS, SENTRI, and FAST, permanent resident cards, foreign passports, enhanced driver's licenses, and Department of Defense IDs, Tribal IDs, or other federally recognized documents.

Temporary licenses don't make the cut, though children under 18 don't need ID for domestic travel. So if you're traveling with kids, at least you don't have to worry about them forgetting their paperwork.

The Takeaway for Travelers

With REAL ID enforcement now in full swing and this $18 fee potentially on the horizon, double-checking your documents before heading to the airport seems like a smart move. Carrying a valid passport or REAL ID-compliant license could save you time, hassle, and the cost of using a biometric kiosk because you left your wallet on the kitchen counter.

The proposed rule is still under consideration, but if it goes through, forgetting your ID will come with a price tag attached. And unlike airline fees, this one doesn't even get you extra legroom.
