EIN Application Prep Checklist
Who needs an EIN
You may need an EIN if you hire employees, form certain entities, have multiple owners, operate as a corporation or partnership, or need one for banking, payroll, taxes, or vendor records.
- Single-member LLCs may still choose to get one for business banking.
- Do not pay third-party sites just to get an EIN.
- Use the legal business name consistently.
What to prepare
Prepare the responsible party name and SSN or ITIN, legal structure, mailing address, physical address, reason for applying, start date, and expected employee count.
- The responsible party should control or direct the entity.
- Match addresses to your official records.
- Save the confirmation notice immediately.
Common mistakes
Avoid duplicate applications, wrong entity type, typos in the legal name, using a nominee as responsible party, and losing the confirmation letter.
- One responsible party can generally apply for one EIN per day online.
- Use a secure IRS page.
- Update records if the responsible party changes.
