How to Fix QuickBooks Payroll Error 15270
QuickBooks stopped your payroll update with: "Error 15270: The payroll update did not complete successfully. The update is missing a file."
The phrase "missing a file" is the key diagnostic. It means Intuit's update server started delivering the update but could not complete it — either because the download was cut short, or because your EIN or service key failed validation and the server withheld the final file. At QuickFix Bookkeeping, those two causes account for the vast majority of 15270 errors we see.
The QuickFix Bookkeeping Distinction
15270 says a file is missing. PS107 says a file is unreadable. 15311 says a file failed signature verification. Three different failure points — three different first fixes.
PS107
File is unreadable
Program file is damaged or corrupted. Fix: reset update cache, repair installation.
15270
This page — file is missing
Server never delivered a file. Fix: reset update download, verify EIN and service key.
15311
File failed signature check
File arrived but digital signature is invalid. Fix: TLS settings, reinstall certificate.
Start here: Reset the QuickBooks update download (Method 1) — this resolves the majority of 15270 cases by forcing a clean, complete re-download of the missing file. If it recurs, Method 2 (EIN and service key) is almost always the reason.

What it means
Error 15270 means the payroll update process started successfully — QuickBooks connected to Intuit's server, began downloading the update package — but the package did not arrive complete. At least one file in the update bundle is absent when QuickBooks tries to install it. The server either stopped delivering mid-download (network interruption) or withheld a file because EIN or service key validation failed.
Your company data is safe. 15270 is an update delivery error. Your existing company file, employee records, and payroll history are completely unaffected.
What Causes QuickBooks Error 15270?
📦
Incomplete Update Download
Primary cause — the update download was interrupted before completion. The cached partial download is what QuickBooks tries to install, and 15270 fires when it finds the missing file. Resetting the update cache forces a complete fresh download.
🔑
Wrong EIN or Service Key
Intuit's server validates your Employer Identification Number and payroll service key before delivering the update package. If either is wrong — including entering a Social Security number instead of an EIN — the server withholds files and QuickBooks reports them as missing.
📋
Expired Payroll Subscription
An inactive or expired payroll subscription causes Intuit's server to deny delivery of the update package entirely. QuickBooks interprets this denial as a missing file. Renewing the subscription and re-running the update resolves this variant immediately.
⚙️
UAC Blocking File Write
Windows User Account Control can prevent QuickBooks from writing the downloaded update file to its destination folder — producing a scenario where the file downloaded correctly but could not be saved, making it appear missing at install time.
🛡️
Firewall or Antivirus Interference
Security software blocking or quarantining update files mid-download produces the same missing-file result as a network interruption. An antivirus quarantine log entry timed to the update attempt is diagnostic.
📶
Multiple QuickBooks Instances
Running more than one QuickBooks session simultaneously during a payroll update causes file write conflicts — two processes compete to write to the same update folder, leaving files incomplete. Always update in single-user mode with all other QB sessions closed.
How to Fix QuickBooks Error 15270 — Step by Step
Start with Method 1 — it resolves the majority of 15270 cases by forcing a clean complete re-download of the update package.
METHOD 1
Reset the Update Cache and Re-Download
Resolves most 15270 cases — incomplete download
Resetting the update cache discards the partial download that caused 15270 and forces QuickBooks to fetch a fresh, complete update package. This is the fastest fix when a network interruption cut the original download short.
1
Close QuickBooks. Open Task Manager (Ctrl+Shift+Esc) → Processes tab → end any running QBW32.exe or QBUpdate.exe processes.
2
Reopen QuickBooks. Go to Help → Update QuickBooks Desktop → Update Now tab. Check the Reset Update box. Click Get Updates and let the download complete fully without interruption.
3
When prompted, close and reopen QuickBooks and install the downloaded updates. Select Install Now when the QuickBooks Update Service window appears.
4
Now run the payroll update: Employees → Get Payroll Updates → Download Entire Update. Ensure you are in single-user mode first (File → Switch to Single-user Mode).
QuickFix tip: "Download Entire Update" rather than "Download Latest Update" is critical for 15270. The standard latest-update route only fetches the delta since your last update — if a file in that delta went missing previously, it will miss it again. The entire update route re-downloads the complete package from scratch.
METHOD 2
Verify EIN and Re-Enter the Payroll Service Key
If 15270 recurs after Method 1
If the error returns after a successful update reset, an EIN or service key problem is the cause. Intuit's update server validates both before delivering files — an incorrect entry causes server-side file withholding that surfaces as 15270 every time.
1
Verify your EIN: In QuickBooks, go to Company → My Company. Confirm the Federal Employer ID Number (EIN) matches exactly what is registered with the IRS. A common mistake is entering a Social Security Number here instead of the business EIN.
2
Remove and re-enter the service key: Go to Employees → My Payroll Service → Manage Service Key. Note the existing service key, then click Edit → Remove → Yes. Click Add, re-enter your service key and EIN, click Next, uncheck Open Payroll Setup, click Finish.
3
After re-entering the service key, confirm the Status shows Active. Then immediately run the payroll update: Employees → Get Payroll Updates → Download Entire Update.
QuickFix tip: The remove-and-re-add process forces QuickBooks to re-validate the service key against Intuit's servers — it is not enough to simply check the key is there. Viewing an existing key and clicking Save does not trigger re-validation. The remove → add cycle does.
METHOD 3
Verify Payroll Subscription is Active
Quick check — 2 minutes
An expired or cancelled payroll subscription causes Intuit's server to block the update delivery — producing 15270 every time regardless of your network or settings. This is a 2-minute check.
Basic, Standard, or Enhanced Payroll:
1
Go to Employees → My Payroll Service → Account/Billing Information. Sign in to your Intuit account and check the subscription status on the QuickBooks Payroll Account Maintenance page.
Assisted Payroll:
1
Go to Employees → My Payroll Service → Account/Billing Information. Once the payroll account maintenance page opens, close it immediately — this action triggers a re-validation of your payroll service in the background. Attempt the payroll update after closing.
METHOD 4
Temporarily Disable User Account Control (UAC)
If UAC is blocking the file write
Windows UAC can prevent QuickBooks from writing the downloaded update file to the program directory — producing a missing-file result even when the download completed. Temporarily disabling UAC during the update resolves this.
1
Press Windows + R → type UserAccountControlSettings → Enter. Move the slider to Never notify. Click OK and restart the computer.
2
After restart, run the payroll update: Employees → Get Payroll Updates → Download Entire Update.
3
Important: Once the update completes successfully, immediately return UAC to its previous setting — Never notify is not a secure permanent configuration. Return to UserAccountControlSettings and move the slider back up.
METHOD 5
Run reboot.bat to Re-Register QuickBooks Components
If DLL/component registration is broken
QuickBooks' reboot.bat file re-registers all Windows DLL and OCX components that QuickBooks depends on. If 15270 is caused by a deregistered or corrupted Windows component, this resolves it without requiring a full reinstall.
1
Close QuickBooks completely. Navigate to your QuickBooks installation folder — typically C:\Program Files\Intuit\QuickBooks [Year].
2
Find reboot.bat in that folder. Right-click it → Run as Administrator. A command window opens, runs through a list of file registrations, and closes automatically when done.
3
Restart your computer after the script completes. Then run the payroll update again.
QuickFix tip: Right-click → Run as Administrator is essential for reboot.bat. Running it with standard user permissions causes it to silently skip the registrations that require elevation — the script appears to complete successfully but changes nothing. Always right-click and select Run as Administrator.
METHOD 6
Update in Selective Startup Mode
Eliminates third-party interference
If Methods 1–5 have not resolved 15270, a background application is interfering with the update download or file write. Selective Startup mode isolates QuickBooks from all third-party processes.
1
Press Windows + R → type msconfig → Enter. General tab → Selective Startup → uncheck Load startup items. Services tab → check Hide all Microsoft services → Disable all. Apply → OK → Restart.
2
After restart, reinstall QuickBooks in Selective Startup mode and then run the payroll update: Employees → Get Payroll Updates → Download Entire Update.
3
After success: Return to Normal Startup — msconfig → General → Normal Startup → Apply → OK → Restart. Then re-enable your third-party services one by one to identify the one causing interference.
METHOD 7
Run Quick Fix My Program from QuickBooks Tool Hub
Last automated fix before manual repair
QuickBooks Tool Hub's Quick Fix My Program tool runs a mini-repair on QuickBooks without requiring a full reinstall — it stops background QB processes, runs a quick repair scan, and restarts QuickBooks cleanly.
1
Close QuickBooks. Open QuickBooks Tool Hub → Program Problems tab → Quick Fix my Program. Let it run to completion.
2
Reopen QuickBooks, go to Employees → Get Payroll Updates → Download Entire Update, and test.

Frequently Asked Questions About Error 15270
What is the difference between Error 15270 and Error 15311?
15270 means a file is missing — the update package was not delivered completely. 15311 means a file arrived but failed its digital signature check — the file is present but QuickBooks does not trust it. They look similar on the surface but point to different root causes. If you have 15270, start with the update reset and EIN verification. If you have 15311, start with TLS settings in Internet Explorer and the digital certificate reinstall.
Why does 15270 keep coming back every payroll cycle?
A recurring 15270 — one that comes back after every successful update reset — almost always means the EIN entered in QuickBooks does not match what Intuit has on file for your payroll subscription. Each time you run a payroll update, Intuit's server re-validates your EIN, fails the check, and withholds the same file. The reset works temporarily because the download completes before validation fails, but the pattern repeats. Verify your EIN in Company → My Company against your IRS EIN letter and correct any discrepancy.
Can I run payroll while 15270 is blocking updates?
You can process payroll using your current tax tables, but running on outdated tables creates compliance risk if tax rates have changed since your last successful update. Before your next payroll cycle, resolve 15270 and confirm the update completes with a current tax table date — visible in Employees → Get Payroll Updates → Payroll Update Info. Never run payroll approaching a quarter-end or year-end deadline with outdated tables.
How do I find my payroll service key if I have lost it?
Your payroll service key is available in your Intuit account at payroll.intuit.com — log in, go to Account → Service Keys. It is also displayed in QuickBooks under Employees → My Payroll Service → Manage Service Key, where you can view the existing key. If neither works, contact Intuit payroll support with your business EIN and they can retrieve or reissue the service key for your active subscription.
