How to Fix QuickBooks Payroll Error 15310
QuickBooks displays error 15310 during payroll subscription validation — QB can't verify the payroll service license for this installation.
Error 15310 is a payroll subscription seat limit or concurrent session validation failure. At QuickFix Bookkeeping, 15310 is distinct from 15276 (EIN mismatch) and 15222 (subscription inactive): 15310 appears when the payroll subscription has exceeded its licensed number of concurrent machines or simultaneous activations — Intuit's servers see the subscription being used on more systems than the licence allows and refuse validation.
15310 vs 15276 vs 15222 — Payroll Subscription Error Distinctions
15310 — this page
Seat limit exceeded — too many concurrent machines using the same payroll subscription. Fix: manage activations at camps.intuit.com or contact Intuit to reset activation count.
15276
EIN mismatch — subscription EIN doesn't match company file EIN. One machine, wrong EIN configuration. Fix: re-enter service key or correct EIN.
15222
Subscription inactive or lapsed — payment failed or account expired. Fix: renew subscription at payroll.intuit.com.
What Causes QuickBooks Payroll Error 15310?
Payroll Subscription Seat Limit Reached
Primary 15310 cause — QB's payroll subscription allows a limited number of simultaneous installations or activations. When this limit is reached (from cloning, multiple reinstalls without deactivating old machines, or company-wide deployment), Intuit's validation server denies the activation and returns 15310. Deactivate unused machines at camps.intuit.com to free up seats.
Company File Restored to New Machine Without Deactivating Old One
A company file was restored or moved to a new computer and payroll was activated on it — but the old machine's payroll subscription was never deactivated. Both machines now count against the subscription limit, potentially exceeding it and producing 15310 on subsequent validation attempts.
Multiple QB Reinstalls Without Deactivating
A series of QB reinstalls (for troubleshooting, upgrades, or system rebuilds) without deactivating payroll before each uninstall accumulates activation counts on Intuit's server. The physical machine may be the same, but Intuit sees multiple activations and applies the seat limit.
Payroll Subscription Type Doesn't Cover Current QB Version
Some payroll subscription types are version-specific. If the subscription was purchased for QB 2022 and the machine is now running QB 2024, Intuit's validation may return 15310 for the new version. Contact Intuit to confirm the subscription covers the current QB version.
Network Blocking Validation Request
A firewall blocking QB's connection to Intuit's subscription validation servers causes 15310 as the validation request times out or receives no response. Temporarily disabling the firewall and retrying confirms if this is the cause.
Stale Payroll Service Key
The payroll service key stored in QB hasn't been validated against Intuit's current servers in a long time — Intuit's system no longer accepts the cached validation data. Re-entering the service key via Employees → My Payroll Service Key forces a fresh validation.
