Recent IRS appointment and ITIN context (2025-2026)
IRS Taxpayer Assistance Centers (TACs) operate by appointment only — call 844-545-5640 to schedule. For ITIN W-7 in-person processing, only designated Certifying Acceptance Agent TACs can verify original passport documents (saves you mailing your passport to Austin, TX). The ITIN application fee is $0 (no IRS fee); third-party Acceptance Agent fees range from $50-$300 per applicant when not using a TAC directly.
H.R.1 / OBBBA effective 2026-05-29 did NOT change Form W-7 ITIN procedures, but the IRS publishes ITIN processing time updates monthly. Current processing time: approximately 7 weeks for new W-7 applications mailed to Austin Service Center. Renewals required for ITINs not used on a federal tax return for 3 consecutive years. The 2024 IRS Strategic Operating Plan allocated $80 billion in funding (later reduced) — TAC hours and locations may shift annually based on Congressional appropriations.
For free tax preparation: 11,000+ VITA (Volunteer Income Tax Assistance) sites nationwide serve households earning under approximately $64,000. TCE (Tax Counseling for the Elderly) sites serve taxpayers 60+. Find sites at irs.treasury.gov/freetaxprep or call 1-800-906-9887. VITA volunteers are IRS-certified annually and can prepare Forms 1040, 1040-SR, 1040-NR (limited), Schedule A, B, C (simple), EIC, Child Tax Credit, ACTC, education credits.
IRS Form W-7 and the Form 1040 series interact via Schedule 8812 (Credits for Qualifying Children and Other Dependents) — ITIN-only filers can still claim the $2,000 Child Tax Credit per qualifying child (US citizen or LPR child with SSN required). The Additional Child Tax Credit refundable portion is $1,700 for tax year 2025. Form 1040-NR filers face different rules; consult a TAC or VITA volunteer for nonresident-alien status questions.
