The blank earning line — the most missed cause: A blank earning record inserted above the earnings in a paycheck silently causes Error 2107. Go to Employees > Payroll Center > Payroll tab > find the employee > Open Paycheck Detail. If any earning row is completely blank (no item, no amount), delete it and save. This is invisible in normal view and overlooked by almost every guide.

Sending Payroll in Multi-User Mode

Most common cause — Direct Deposit payroll must be sent from the QB host computer in single-user mode. Attempting to send from a workstation in multi-user mode produces Error 2107 every time.

Invalid Security Certificate

The QuickBooks digital security certificate is expired, missing, or not trusted by Windows. QB uses this certificate to establish a secure connection to Intuit's payroll servers. Installing the certificate from the QB .exe file restores the connection.

Blank Earning Record in a Paycheck

A completely blank earning line in the paycheck detail causes QB to fail when trying to transmit the paycheck data. Open Paycheck Detail for the affected employee and delete any blank earning rows.

Incorrect System Date / Time

An incorrect system clock breaks SSL certificate validation — QB's connection to Intuit's servers requires the system date/time to be accurate. Even a few hours difference can cause 2107 during Direct Deposit transmission.

Firewall or Antivirus Blocking QB

Security software blocking QB's outbound connection to Intuit's payroll servers. This is common after a security software update resets QB's exception rules. Add QB and its services to the exception list.

Bank Account Changed — Not Updated in QB

The company bank account for payroll funding was changed at the bank but the Direct Deposit bank account in QB was not updated. Intuit cannot process the deposit against the old account details.

METHOD 1 Switch to Single-User Mode Before Sending Payroll Do this first

Direct Deposit payroll must be sent from the server/host computer in single-user mode. Sending from a workstation or while in multi-user mode is the most common cause of 2107.

METHOD 2 Check Paycheck Detail for Blank Earning Records

A blank earning line in the paycheck silently blocks transmission. This is a QB data issue that persists regardless of network or firewall fixes.

METHOD 3 Fix System Date/Time and Install QB Security Certificate

METHOD 4 Add QB to Firewall Exceptions + Check Company Name

Did my employees still get paid if Error 2107 appeared?

Not necessarily. Error 2107 means the payroll data was not successfully transmitted to Intuit for processing. If QB shows the error before the payroll was sent, the direct deposits were not initiated. Log into the Payroll Account Management Portal at payroll.intuit.com and check the payroll history to confirm whether Intuit received the submission. If the payroll is not listed there, it was not sent and you need to resend it. Do not create new paychecks — resend the existing ones after fixing the cause of 2107.

Why would Error 2107 appear when nothing changed?

The most common sudden-onset 2107 cause when nothing appears to have changed is a Windows security update that reset QB's firewall exception rules or invalidated the QB security certificate. Security software updates frequently remove exceptions that QB relies on. The second most common sudden cause is another user logging into QB on a workstation at the same moment payroll was being sent — which temporarily pushed it into multi-user mode mid-transmission.
