Form W-7 ITIN Application

Form W-7 is the application for an Individual Tax Identification Number (ITIN), the IRS's tax ID for non-residents who need to file US taxes or comply with US tax forms. Most Wyoming LLC owners do NOT need an ITIN. This guide explains when you do.

Answer

Form W-7 is the IRS application for an Individual Tax Identification Number. ITIN is required only if you sell on PayPal (which uses ITIN for personal verification) or file a personal US Form 1040-NR. You do NOT need ITIN for Amazon, Stripe, Shopify, Mercury, Wise, or your Wyoming LLC's EIN. ITIN application requires Form W-7, original passport (or certified copy), and supporting documents. Processing takes 8 to 12 weeks. WyomingLLC offers ITIN as a $297 separate add-on.

When you actually need ITIN

You sell on PayPal Business and PayPal asks for personal verification (PayPal uses ITIN for the responsible party)
You file Form 1040-NR (US personal tax return for non-residents)
You claim US tax treaty benefits and the payer requires ITIN on Form W-8BEN (rare)
You own US real estate and file 1040-NR for rental income

When you do NOT need ITIN

Operating an LLC with EIN (the LLC has its own tax ID)
Selling on Amazon, Stripe, Shopify, eBay, Etsy (these use the LLC's EIN, not your ITIN)
Opening Mercury, Relay, or Wise Business (they use LLC + EIN, not ITIN)
Filing Form 5472 (uses LLC's EIN, not your ITIN)
Claiming W-8BEN-E treaty benefits as an entity (uses EIN as the foreign TIN field is optional)
