QuickBooks Payroll Error 15240, 15241 & 15243: Fix the "Update Did Not Complete" Loop

You try to download a payroll tax-table update and QuickBooks stops with one of:

“Error 15241: The payroll update did not complete successfully.” “Error 15240: The update program is unable to update.” “Error 15243: The update did not complete successfully.”

What they share: all the 15xxx update errors are QuickBooks failing to install a file it downloaded. The number-one cause is a single Windows service — Intuit QuickBooks FCS (the File Copy Service that writes the update into place) — being disabled. Fix that service and most of these clear immediately.

Fix 1: Re-enable the Intuit QuickBooks FCS service (fixes most 15xxx errors)

1. Close QuickBooks completely.
2. Press Win + R, type services.msc, press Enter.
3. Scroll to Intuit QuickBooks FCS → right-click → Properties.
4. Set Startup type to Manual.
5. Under Service status, click Start (if it’s already running, click Stop then Start), then OK.
6. Reopen QuickBooks → Employees → Get Payroll Updates → tick Download Entire Update → Update.

That sequence alone resolves the large majority of 15241/15240/15243 reports.

Fix 2: Run QuickBooks as administrator

If the service is on but the update still won’t install, QuickBooks may lack permission to write the file:

1. Close QuickBooks.
2. Right-click the QuickBooks desktop icon → Run as administrator.
3. Retry Employees → Get Payroll Updates → Download Entire Update.

Fix 3: Check your date, time & active payroll subscription

The updater rejects files when the clock is wrong or the subscription can’t be verified:

• Fix the system date/time (right-click the taskbar clock → Adjust date and time → turn on Set time automatically).
• Confirm your subscription is active: Employees → My Payroll Service → Account/Billing Information.
• Re-validate the service key: Employees → My Payroll Service → Manage Service Key → Edit → Next → Finish (this re-checks the key without changing it).

Fix 4: Make sure QuickBooks itself is current

An out-of-date QuickBooks release can’t always read the newest tax table.

• Help → Update QuickBooks Desktop → Update Now → tick Reset Update → Get Updates.
• Restart QuickBooks and accept the install when prompted, then retry the payroll update.

Fix 5: Repair the install (when 15xxx persists)

A damaged install or missing Microsoft component is the usual cause of a stubborn 15243.

1. Open the QuickBooks Tool Hub → Program Problems → Quick Fix my Program.
2. If that fails, Installation Issues → QuickBooks Install Diagnostic Tool (repairs .NET, MSXML, C++).
3. Reboot and retry the update.

Fix 6: Verify the digital signature certificate

Errors 15240/15243 sometimes mean Windows doesn’t trust the QuickBooks executable’s Intuit certificate:

1. Browse to your install folder, e.g. C:\Program Files\Intuit\QUICKBOOKS YEAR.
2. Right-click QBW32.exe (or QBW.exe) → Properties → Digital Signatures.
3. Select Intuit, Inc. → Details → View Certificate → Install Certificate → Local Machine → finish, then reboot and retry.

FAQ

Why does the FCS service keep turning off? Some “PC cleaner” and antivirus tools set unused services to Disabled. If error 15xxx returns, re-check Startup type is Manual and exclude QuickBooks from your optimizer.

Is this the same as a PSxxx error? No — PS038/PS032 are about stuck or unsent paychecks and subscription validation, not the updater. See the dedicated PS038 fix for those.

Do I need to be on the server? Run the payroll update on the computer where QuickBooks is installed for that user. Payroll updates are per-installation, unlike the multi-user H202 connectivity fixes.
