How to Fix QuickBooks Payroll Error 15270
QuickBooks displays error 15270 when attempting to download or install payroll updates.
Error 15270 is an SSL certificate chain validation failure. Unlike 15225 (SSL state cache corruption) or 15217 (IE Advanced Settings misconfiguration), 15270 specifically means an intermediate certificate in the trust chain between Intuit's server and your machine is missing or has expired. At QuickFix Bookkeeping, the 15270-specific fix is to download and install the missing intermediate certificate from Microsoft's root certificate program — or to force Windows to update its certificate store.
The QuickFix Bookkeeping Distinction — 15270 vs 15225 vs 15227
15270 — this page
SSL certificate chain validation — intermediate certificate missing or expired. Fix: update Windows certificate store, run Windows Update, clear SSL state.
15225
SSL session cache corrupted — the cached certificate verification data is stale. Fix: IE → Content tab → Clear SSL State.
15227
Windows DLL registration corruption — softpub.dll and WinTrust.dll registrations are broken. Fix: regsvr32 to re-register both DLLs.
What Causes QuickBooks Payroll Error 15270?
Missing Intermediate Certificate
Primary 15270 cause — SSL certificate chains work by chaining from the end certificate through one or more intermediate certificates to a trusted root certificate. If an intermediate certificate is missing from Windows' certificate store, the chain can't be validated and QB reports 15270. Windows Update normally keeps these current; if Windows hasn't been updated recently, intermediate certs may be missing.
Expired Certificate in Chain
One of the certificates in the trust chain has expired. While Intuit's end certificate is current, an intermediate certificate that vouches for it may have expired — the chain validation fails even though Intuit's own certificate is valid. Windows Update or a manual certificate download from Microsoft's program resolves this.
Outdated Windows / Root Certificates
Very outdated Windows installations may lack the root certificate update that includes Intuit's certificate authority. Windows 7 SP1 and Windows 8.1 without updates are commonly affected. Running Windows Update to the latest available updates installs the required root and intermediate certificates.
Firewall Performing SSL Inspection
Corporate firewalls that perform SSL inspection intercept Intuit's certificate and present their own certificate to QB. If QB's validation checks the expected Intuit chain and finds the firewall's certificate instead, 15270 appears. Disabling SSL inspection for *.intuit.com in the firewall or using a policy exception resolves this.
Incorrect System Date/Time
SSL certificates are time-sensitive — if the system clock is significantly wrong (more than a few minutes off), Windows may incorrectly determine that a valid certificate has expired or isn't yet valid. Check that the system date, time, and timezone are correct before attempting other 15270 fixes.
Antivirus SSL Scanning
Some AV products perform their own SSL certificate scanning that can interfere with QB's certificate validation. The AV may present its own certificate to QB's update connection, breaking the expected trust chain. Adding *.intuit.com to AV trusted sites or disabling AV SSL inspection resolves this.

Corporate firewalls performing SSL inspection on *.intuit.com traffic are the most common cause of persistent 15270 — the firewall administrator needs to add Intuit's certificate chain to the SSL inspection bypass list.
