When users try to send paychecks or update payroll, QuickBooks Payroll Error PS038 appears. This is frequently the result of faulty files, expired subscriptions, or stalled paychecks in the "Send Payroll Data" queue. Make sure your QuickBooks software is up to date and your payroll subscription is current before beginning any troubleshooting. To correct any data integrity issues, go to "File" > "Utilities" > "Verify Data," then "Rebuild Data" to verify and rebuild your QuickBooks data.
