Does a W-9 expire?
No. Unlike a Form W-8, a W-9 carries no expiration date and no annual renewal requirement. It stops being valid when the facts it certifies stop being true.
No expiration date, no annual renewal
- Expiration date on the form
- None
- Annual renewal required?
- No
- Stays valid until
- Your name, entity classification or TIN changes
- Payer retention
- Generally at least four years
- Compare with Form W-8BEN
- That one does expire, generally at the end of the third calendar year after signing
- Common payer practice
- Refreshing files every one to three years as an internal control
The six events that void your W-9
A W-9 is a snapshot of the facts as they stood on the day you signed it. Nothing on it goes stale by itself, so nothing needs renewing on a calendar. What ends its validity is a change in one of the facts it certifies, and there are six of those. When one happens, the form sitting in a payer’s file is wrong in a way that eventually shows up as a Form 1099 reporting the wrong name, the wrong number, or income attributed to an entity that no longer exists. You then have to tell every payer holding a copy, which is the practical argument for keeping a list of who has one. None of this is hard. It is just easy to forget, because the trigger is usually a life event rather than anything that looks like tax.
Moving house does not invalidate anything, because the IRS matches on name and TIN rather than on where you live. Send an updated form all the same. Otherwise your Form 1099 goes to the old address and you file a return without knowing what was reported about you.
Why payers ask anyway
You will still get annual requests. None of the following is a legal requirement, and all of them are reasonable practice:
- Vendor records drift, and a refresh cycle catches entity changes nobody bothered to report.
- A signed form from this year is easier to defend in an audit than one from 2017.
- New ERP, new vendor portal, fresh collection.
- After an acquisition the new entity usually re-collects everything.
- Documented annual solicitations support penalty relief if a TIN turns out to be wrong. Detail
Complying costs you two minutes. Refusing on the grounds that the old form has not expired is technically correct and practically counterproductive: a payer that cannot satisfy its own controls may put your payments on hold, and nobody in accounts payable is going to lose that argument on your behalf. So if the request arrives every January, treat it as January paperwork and stop thinking about it. There is one situation worth pushing back on. When the request comes from a company that has never paid you, or arrives by a channel you would not trust with your Social Security number, the expiration question is beside the point and the right move is to verify who is asking. How to check
How long payers should retain them
| Question | Practice |
|---|---|
| Minimum retention | At least four years from the date of the form or the last payment, so the payer can substantiate what it reported |
| Common policy | Life of the vendor relationship plus four years |
| Format | Paper or electronic. Electronic storage is acceptable provided the record is complete and retrievable |
| Security obligation | These files contain Social Security numbers. Access control, encryption at rest and a deletion schedule are the minimum. Detail |
| Superseded forms | Keep the old version alongside the new one, because it documents what was reported in earlier years |
W-9 and W-8 expiration compared
| Form W-9 | Form W-8BEN | |
|---|---|---|
| Who files it | A U.S. person | A foreign individual |
| Expiration | None | Generally the last day of the third calendar year after signing |
| Renewal | Only on a change of facts | Periodic renewal required |
| Treaty claims | Not applicable | Often the reason for filing |
Payers dealing with both populations sometimes apply the W-8 renewal cycle to everyone. That is over-collection rather than an error of law. Full comparison
Frequently asked questions
Does a W-9 expire?
Form W-9 carries no expiration date. It remains valid until the information on it changes or the requester asks you to recertify.
Do I need a new W-9 every year?
There is no annual requirement anywhere in the rules. Some payers request one every year as an internal control, which they are free to do, but nothing obliges them or you.
How long should a payer keep a W-9?
At least four years, so it can substantiate the name and TIN it reported if the IRS asks. Many organizations keep them for the life of the vendor relationship plus four years.
Is a Form W-8 different?
Yes, importantly. A Form W-8BEN generally remains valid until the end of the third calendar year after signing, and then has to be renewed. That expiration rule is often misapplied to Form W-9. Comparison
