Illustrative scene of business preparation

Confirm that an ITIN is the right identifier

An ITIN is for specific U.S. tax-administration purposes. It is different from an EIN for a business and does not itself create permission to work or immigration status. Establish the reason for the application before gathering sensitive identity documents.

Use the current instructions

Form W-7 and its instructions explain application categories, documentation and any return or exception requirements. Your facts determine the appropriate route. Avoid a generic promise that every applicant can apply using the same evidence.

Protect original identity documents

Discuss acceptable document handling and any approved verification process before sending anything. The public Infinity Filer site does not accept passport uploads or identity numbers. Confirm who is performing any acceptance-agent work and verify their status where applicable.

Separate assistance from the IRS decision

Ask for a written scope covering preparation and follow-up. The IRS controls processing and approval, and may request additional information. An ITIN can support online EIN eligibility only when the other IRS online requirements are also met.

Your preparation checklist

  • Write down the exact business or document outcome you need.
  • Confirm the legal entity name, formation jurisdiction and current status where relevant.
  • Identify who can authorize the work and review the final information.
  • Separate the initial service from later renewals, official charges and additional professional work.
  • Keep sensitive records outside general website enquiries; agree a handling process first.
  • Retain the final scope, receipts and actual agency/provider confirmations.

Costs, scope and next steps

Infinity Filer’s itin application assistance service is $170 USD. Review what is included and excluded on the service page. If you select other services, the builder shows their separate charges. Quote-only items need confirmation and are not represented as free.

If you already have a formation package, check whether the requested work is included before adding it again. A specialized document or a different scope may require an upgrade quote. PKR payments include the stated 15% company conversion charge after the USD amount is converted.

For example, a standalone $10 service paid in USD remains $10. A PKR payment uses the current reference rate and then adds the 15% charge; a stale or unavailable rate requires confirmation. This payment example does not change the eligibility or work included in the service.
