E-signature for HR onboarding: I-9, W-4, EU and Germany

By the nodshake team. Published 14 October 2026, updated 14 October 2026.

Most onboarding paperwork can be signed electronically, but the rules differ. The US allows an electronic Form I-9 and W-4 if the system meets set controls. EU written terms can be electronic if the worker can access, store and print them and the employer keeps proof of transmission or receipt. In Germany, termination still needs wet ink. This is information, not legal advice.

Key points

  • Form I-9 must be kept three years after hire or one year after employment ends, whichever is later; if kept electronically, the system needs an audit trail.
  • The remote document check for I-9 is only for employers in good standing in E-Verify.
  • Germany: BGB 623 excludes electronic form for termination; the written-terms duty (NachwG) allows text form from 1 January 2025.
  • State, UK and other EU member state rules were not checked.

EU and Germany

Directive (EU) 2019/1152 Art. 3 lets written information be given electronically if it is accessible to the worker, can be stored and printed, and the employer retains proof of transmission or receipt.[4] Germany adds its own form rules.[5][6]

What your signing system should let you show

  • Who signed and when, kept as a record you cannot quietly edit. See the audit trail guide.
  • Proof of delivery and receipt for EU written terms.
  • A retention period you control, and an export of the record.
  • A way to print a confirmation on request, as the I-9 rule asks.

For volume hiring, bulk send and an API can feed your HR system; see nodshake for business. Ask a lawyer before you rely on a signing flow for a regulated form.

Questions

Can Form I-9 be signed electronically?
Yes, if the electronic system meets the controls in 8 CFR 274a.2: integrity, indexed retrieval, an audit trail, and a record verifying the signer's identity. This is information, not legal advice.
Can an employment termination be e-signed in Germany?
No. BGB section 623 says termination by notice or agreement needs written form and excludes electronic form.
Can an employer send EU written terms by email?
Directive 2019/1152 Art. 3 allows it if the worker can access, store and print the information and the employer keeps proof of transmission or receipt.
