US ITIN Renewal for Pakistani Holders: 2026 Form W-7 Renewal Process and Expiry Rules

For Pakistani holders of a US Individual Taxpayer Identification Number, the question of whether the ITIN is still valid is one most people forget about until they need to file a return or claim a treaty benefit. The IRS expires unused ITINs automatically after three consecutive tax years, and a return filed with an expired ITIN is processed slowly with refunds delayed by months. This guide sets out exactly when an ITIN expires, how to renew it through Form W-7, and how to coordinate the renewal with the Certified Acceptance Agent process so the original passport never has to leave Pakistan.

When an ITIN Expires Automatically

An ITIN expires on 31 December of the third consecutive tax year in which it was not used on a US federal tax return. The expiry rule applies regardless of the original issuance date or the holder's circumstances. A Pakistani applicant who obtained an ITIN in 2020 to file a single return and then did not file again until 2025 will find that the ITIN expired on 31 December 2023 (the third unused year following 2020).

A separate expiry schedule applies to ITINs issued before 2013, identified by middle digits in the 70-88 range. The IRS staged these expiries across multiple years (2016 to 2020), and ITINs in this range that have not been renewed are expired by default. Pakistani holders with pre-2013 ITINs who have not renewed should assume the ITIN is expired regardless of recent use.

The Renewal Form: Form W-7 with Renewal Box Checked

Renewal uses the same Form W-7 as a new ITIN application, with the renewal box checked at the top right of the form. The form requires biographical information (which should match the original ITIN application unless circumstances have changed), the existing ITIN number, the reason for the renewal, and the supporting identity documentation.

The reason for renewal does not need to mirror the original reason. A holder who first obtained an ITIN to claim treaty benefits can renew on the basis of a current tax filing obligation, and vice versa. The W-7 instructions require the box selection to match the current circumstances at the time of renewal.

Certified Acceptance Agent: The Practical Route for Pakistani Renewals

The same Certified Acceptance Agent process that works for new ITIN applications also works for renewals. The CAA verifies the original passport in person, retains a certified record, and submits the W-7 with the Certificate of Accuracy in lieu of the original document. The Pakistani holder's passport never leaves Pakistan, the IRS receives an authoritative document verification from a CAA, and the renewal processes faster than mail-only submissions.

Pakistani holders renewing an ITIN should coordinate the CAA appointment alongside the Form W-7 preparation. Standard CAAs are listed publicly on the IRS website. The CAA fee is typically separate from any legal advisory fee and varies by provider.

Processing Timelines and Tax Return Coordination

Standard processing for a renewal Form W-7 is 7 weeks during non-peak months. During peak filing season (15 January to 30 April), processing extends to 9 to 11 weeks. The same extension applies to applications mailed from overseas. Pakistani holders renewing in the run-up to the April 15 US tax filing deadline should plan to either file the renewal alongside the tax return (preserving the timely-filing date even though the return is processed only after the renewal completes) or to file a Form 4868 extension and complete the renewal before the extended October deadline.

A return filed with an expired ITIN is not rejected; it is processed slowly. The IRS marks the return as awaiting ITIN renewal, processes the renewal alongside the return, and issues any refund only after both are complete. The combined timeline can extend to four to six months. For Pakistani holders relying on tax refunds (FIRPTA over-withholding recovery is the most common case), the delay is material and worth avoiding through proactive renewal.

When to Combine Renewal with Other ITIN Work

Some Pakistani ITIN holders are also applying for ITINs for spouses or dependants, transitioning from one filing reason to another, or addressing FIRPTA-side documentation. Where multiple ITIN-related activities are running in parallel, combining them into a single coordinated submission is more efficient than handling each separately. The CAA can certify documents for all family members at the same appointment, the W-7s can be filed together, and the IRS's ITIN Operations centre processes coordinated submissions more efficiently than disconnected ones.

The right time to schedule the renewal is several months before the ITIN is needed for a filing or claim, not when the deadline is approaching. Pakistani holders who are aware their ITIN is approaching the three-year unused mark should renew now rather than waiting for the next tax event.

A Word on How This Work Should Be Handled

The route described above is governed by specific regulations and procedural rules that produce predictable outcomes when handled correctly and unpredictable outcomes when handled casually. The figures, deadlines, and procedural steps in this guide are accurate as at 29 April 2026 and should be re-verified against the relevant official source before any application decision is made. Where any element of the framework changes between now and the application date, the changes will affect outcomes; static guides are useful but not a substitute for current verification.

LexForm prepares each application as legal work, not as a form-filling exercise. Where the route is genuinely a strong fit for an applicant's circumstances, careful preparation produces a clean grant on first application. Where the route is not the right fit, the same careful preparation surfaces that fact early, before time and fees are committed. The first step in either case is a short eligibility review against the applicant's specific facts, with no fee for the initial assessment.
