Fingerprint Requirements for New Members

What They Need

Important: No Sharing

Each person needs their OWN fingerprints. Your existing EFT file only works for YOU. Your spouse, child, or anyone else needs their own set.

When Do They Need to Submit?

For Existing Items

Nothing needed. Items already approved in the trust don't require additional fingerprints. The new responsible person can legally possess them once properly added to the trust.

For New Applications

Submit with next Form 1 or Form 4. When you file your next NFA application, ALL current responsible persons must submit fingerprints—including newly added members.

Timeline Example

  1. January: You add your spouse to trust
  2. January: Spouse can now possess existing NFA items ✓
  3. March: You buy new suppressor
  4. March: BOTH you and spouse submit fingerprints for Form 4

Step-by-Step Process

Step 1: Amend Your Trust

Add the new responsible person to your trust document. Most NFA trusts include a simple amendment process.

Step 2: Get Their Fingerprints

Step 3: Convert to EFT

Step 4: Store Safely

Common Questions

Can they use my fingerprints?

No. Fingerprints are biometric identifiers unique to each person. They need their own.

Do they need fingerprints before being added?

No. They can be added to the trust first, then get fingerprints before the next application. But it's smart to get fingerprints ready in advance.

What if we remove them later?

If someone is removed from the trust, they no longer need to submit fingerprints for future applications. Remove them via trust amendment before filing the next Form.

Does this apply to beneficiaries?

Only if they have current possession rights. Future beneficiaries who can't currently possess trust property typically aren't responsible persons.
