Do You Need a NIE to Become Autonomo or Start a Company?

Key facts
  • Yes — a NIE is required to register as self-employed (autónomo) or to form a company.
  • It is your tax ID (NIF) with Hacienda and your reference for social security.
  • Company founders and directors each need a NIE; the company gets its own NIF.

You cannot register as autonomo or incorporate a Spanish company without a NIE. It is the number Hacienda and social security use to identify you as a taxpayer and contributor.

Where the NIE is required

  • Registering as autónomo: with the tax office and social security.
  • Incorporating an S.L.: founders/administrators are identified by NIE on the deed; the company itself receives a company NIF.
  • Invoicing and VAT: filed under your NIE acting as NIF.

Get the number first

Founders abroad usually obtain the NIE remotely before signing, so incorporation isn’t delayed — see how to get your NIE online. If you’ll also be employed, see NIE to work in Spain.
