Running payroll is stressful enough without your accounting software throwing errors mid-update. If you've encountered QuickBooks Error 15215 while trying to update your payroll tax tables, you're not alone — it's one of the more common update errors QuickBooks Desktop users face. The good news: it's almost always fixable with a few targeted steps.

This guide walks through exactly how to fix Error 15215 so you can get your payroll update completed and your team paid on time.

Quick Overview: Why This Error Happens

QuickBooks Error 15215 typically occurs because the software can't verify the digital signature of the update file, or because something is actively blocking the connection to Intuit's servers. The most common culprits are:

Another instance of QuickBooks running elsewhere Antivirus or firewall software interfering An incorrect system clock Corrupted installation files A shaky internet connection

Knowing the likely cause helps you jump straight to the right fix instead of guessing.

Step-by-Step Fix Step 1: Close Every Open Instance of QuickBooks

Before anything else, make sure QuickBooks isn't open anywhere else on your network — including other workstations if you're on a multi-user setup. Fully exit the program, then relaunch it.

Step 2: Fix Your System Date and Time

An incorrect date or time will cause QuickBooks to fail digital signature checks:

Click the clock in your taskbar Select Adjust date/time Correct the date, time, and time zone Restart your computer Step 3: Try Updating in Selective Startup Mode

This isolates QuickBooks from background programs that may be conflicting:

Press Windows + R, type msconfig, and hit Enter Under the General tab, choose Selective Startup Uncheck Load startup items Restart, then try the payroll update again Step 4: Reconfigure Your Internet Connection Settings In QuickBooks, go to Help > Internet Connection Setup Select Use my computer's Internet connection settings Click Next, then Done Step 5: Temporarily Turn Off Antivirus/Firewall

Security tools can block QuickBooks from reaching Intuit's update servers. Disable them temporarily, run the update, and re-enable them once finished. If it works, add QuickBooks as a permanent exception in your antivirus settings.

Step 6: Run QuickBooks as Administrator

Right-click your QuickBooks icon and choose Run as administrator before attempting the update again. This resolves permission-related conflicts.

Step 7: Use the QuickBooks Tool Hub

Intuit's free Tool Hub application bundles fixes for exactly this kind of issue:

Download and install the Tool Hub from Intuit's official site Open it and go to Installation Issues Run the diagnostic and repair tool Step 8: Reset the Update and Try Again Go to Help > Update QuickBooks Desktop Click Update Now Check the Reset Update box Click Get Updates Payroll Update Checklist

Before re-running your payroll update, quickly confirm:

Your payroll subscription is active and not expired Your service key and EIN are entered correctly You're connected to a stable internet connection QuickBooks is updated to the latest available release When to Contact Support

If you've worked through all the steps above and Error 15215 still won't clear, it may point to a deeper issue — such as a damaged QuickBooks installation or a network-level restriction from your IT environment. At that point, it's worth contacting QuickBooks support or a certified ProAdvisor rather than continuing to troubleshoot manually.

Final Takeaway

Most cases of Error 15215 come down to a handful of predictable causes: a background conflict, a clock mismatch, or a blocked connection. Working through the steps above in order will resolve the vast majority of cases, letting you complete your payroll update without further delay.
