What is QuickBooks Error 15240?

QuickBooks Error 15240 is a payroll update error that prevents users from downloading or installing the latest payroll tax tables and updates. This error essentially blocks your access to critical payroll functionality, making it impossible to run payroll accurately or comply with current tax regulations.

The error typically manifests with messages indicating that QuickBooks cannot verify the digital signature of the payroll update files or encounters connectivity issues with Intuit's servers. When this happens, your payroll system becomes temporarily unusable until the underlying issues are resolved.



Root Causes of QuickBooks Error 15240

Understanding why this error occurs helps in both fixing and preventing it. Here are the primary culprits behind QuickBooks Error 15240:

Internet Connectivity Issues

Poor or unstable internet connections frequently trigger this error. QuickBooks requires a stable connection to communicate with Intuit's servers for payroll updates, and any interruption can cause Error 15240.

Firewall and Antivirus Interference

Security software often blocks QuickBooks from accessing necessary update servers. When your firewall or antivirus program identifies QuickBooks update requests as potential threats, it prevents the connection, resulting in this error.

Corrupted Installation Files

Damaged or corrupted QuickBooks installation files can prevent proper communication with update servers. This corruption often occurs due to incomplete installations, system crashes, or malware infections.

Outdated QuickBooks Version

Running an outdated version of QuickBooks Desktop can create compatibility issues with current payroll update servers, leading to Error 15240.

Windows Registry Problems

Corrupted registry entries related to QuickBooks can interfere with the software's ability to process updates correctly.

Internet Explorer Settings

Since QuickBooks relies on Internet Explorer for secure connections, incorrect IE settings can prevent successful payroll updates.
