If you have a US LLC or you get paid through Stripe or PayPal as a non-US person, you have probably run into both terms. W-8BEN. ITIN. People mix them up constantly – including people who handle compliance for a living. But they are completely different things. Treating them as the same creates real problems: wrong withholding, unfiled returns, IRS compliance gaps that quietly build up over time.

Here is what each one actually is – and what it is not.

What the W-8BEN Actually Does

The W-8BEN is a form, not a number. You fill it out and hand it to whoever is paying you – Stripe, PayPal, a US client, any withholding agent. It communicates one thing: you are not a US person, so do not apply domestic withholding rules to my payments.

Without it, default withholding on certain US-sourced income types – royalties, dividends, passive income generally – can hit 30%. The W-8BEN is your foreign status declaration to your payer. It never goes to the IRS. It stays with whoever is paying you.

What the ITIN Actually Is

The ITIN works differently. It is a tax identification number the IRS issues to individuals who cannot get a Social Security Number – non-resident founders, NRPs, foreign LLC members.

If you have earned income through a US LLC and need to file a US tax return – a Form 1040-NR, for instance – you cannot do that without an ITIN. It is your permanent tax identity with the IRS. You apply through Form W-7, and once issued, it does not expire unless it goes unused across several consecutive filing years. Xpezia’s ITIN service handles the application and certification process for founders filing from Pakistan.

The Difference in Plain Terms

One is a declaration. The other is an identifier.

The W-8BEN is a self-completed form with a built-in expiry – valid for the calendar year it is signed and the three years that follow. No IRS application involved. You fill it in, send it to your payer, and that is the end of its job.

The ITIN is IRS-issued and permanent. You apply, the IRS reviews your documents, and once assigned, that number follows you across every US tax filing you ever make. You do not give it to a payer – it belongs to your relationship with the IRS, not your payer’s.

A practical example: a Pakistani founder running a US LLC submits a W-8BEN to Stripe so Stripe does not apply a 30% withholding rate on service income. That is the W-8BEN working as intended. At year-end, the same founder may need to file a 1040-NR to report US business income. That filing requires an ITIN. The W-8BEN Stripe received has nothing to do with it. Different purposes, different relationships.

The Pakistan-Specific Reality

Most W-8BEN guides assume you are from a country with a US tax treaty. That treaty – where it exists – lets you reduce withholding rates on certain income types through Part II of the form, sometimes all the way to 0%.

Pakistan currently has no income tax treaty with the United States.

This changes how the W-8BEN functions for Pakistani founders in a fairly fundamental way. Part II of the W-8BEN – the treaty benefits section – does not apply to you. Leave it blank. Do not fill it in. Completing it would be a false claim of treaty benefits that simply do not exist, and that is not a minor error.

For Pakistani founders, the W-8BEN is a defensive tool, not a reduction mechanism. It stops your withholding agent from applying incorrect domestic rates. It does not reduce or eliminate withholding through treaty. These are completely different outcomes, and most generic compliance guides never draw this distinction clearly.

Why Founders Search for a “W-8BEN Number”

Some platforms ask for your “W-8BEN number” during onboarding. This phrase means nothing. The W-8BEN is a form – it does not generate a number, a code, or any kind of identifier.

When a platform asks you this, they are likely asking for a Tax Identification Number – an SSN or ITIN – to complete the withholding form. Their phrasing is just wrong. If a service provider asks for your “W-8BEN number” as though it is a real thing, that tells you something about how well they understand what they are handling. For many income types – passive income especially, where no treaty benefit is being claimed – you can submit a W-8BEN without a TIN at all.

A Compliance Gap Worth Knowing About

If you submit a W-8BEN to Stripe but never file a tax return using your ITIN, you are not in a clean position. The IRS does receive information from withholding agents, and your LLC’s EIN filings create a paper trail. A W-8BEN sitting on Stripe’s side with silence on the IRS side is not neutral – it is a gap that can surface later as an unfiled return issue.

The W-8BEN handles your relationship with your payer. Your ITIN and annual return handle your relationship with the IRS. Both need to be in order.

A Note on W-8BEN-E for Entities

If you are operating a US LLC and need to complete a W-8BEN-E – the entity version – the requirements shift. Entity-level forms typically require an Employer Identification Number, which is separate from your personal ITIN. The EIN identifies the LLC to the IRS. Your ITIN identifies you as the individual member. Different layers of compliance entirely. The EIN Guide covers entity identification if you need it.

What to Do Next

The path is straightforward once you know which piece goes where.

If you receive US payments through Stripe, PayPal, or a US client, submit a W-8BEN confirming your foreign status. Leave Part II blank – Pakistan has no US treaty. This prevents incorrect withholding on covered income types.

If your US LLC has business income and you need to file a 1040-NR, get your ITIN through the W-7 process before or alongside that filing. Xpezia’s ITIN service handles this from Pakistan. If your entity needs an EIN, the EIN Guide is where to start.
