EIN application tips for non-residents 2026: what changed and what works
Form SS-4 fax process remains the standard. Recent IRS processing changes and tips for fastest approval.
Form SS-4 best practices
Line 7b: enter 'Foreign' for owner with no SSN/ITIN. Line 8a: LLC. Line 9a: typically 'Disregarded entity' for single-member LLC. Line 10: 'Started new business' or specific reason. Sign and date Line 18.
Common mistakes: missing signature, incomplete address, wrong tax classification. Each error causes IRS rejection and 7-10 day delay.
Faxing the form
Fax to IRS international EIN unit: 855-641-6935 (current as of 2026). Fax during US business hours (9am-5pm Eastern) for fastest processing. Keep the fax confirmation page; it's your evidence of submission.
Most formation services handle Form SS-4 fax on customer's behalf. Delewarellc includes EIN service in $297 bundle.
After faxing
Wait 5-7 business days for response. IRS sends CP 575 (EIN confirmation letter) via fax or mail. If no response by day 10, call IRS Business and Specialty Tax Line (800-829-4933) to check status.
Have your fax date and confirmation number ready when calling.
