Frequently Asked Questions

1. Does QuickBooks Error 15311 affect payroll tax table updates?

Yes. When this error occurs, QuickBooks cannot establish a secure connection to Intuit’s servers, which prevents the payroll tax table from updating. Ensuring valid digital signatures and an active payroll subscription allows these updates to be processed correctly.

2. Can QuickBooks Error 15311 occur due to antivirus or firewall interference?

Yes. Security applications sometimes block QuickBooks background processes or digital certificate validation. Configuring firewall settings to allow QuickBooks executables (QBW32.exe, QBUpdate.exe) can prevent such interference.

3. What happens if I ignore QuickBooks Error 15311 and continue working offline?

If the error is ignored, payroll updates and tax table downloads will fail, leading to outdated tax calculations. Over time, this can result in compliance discrepancies during payroll processing.

4. How can I check if my QuickBooks digital signature is valid?

Navigate to C:\Program Files (x86)\Intuit\QuickBooks, locate QBW32.exe, right-click the file, and select Properties → Digital Signatures. If the certificate is missing, expired, or invalid, reinstall the certificate under the Current User store to restore validation.
