My Firewall is blocking TurboTax files

About Firewalls and TurboTax

If you find that you are unable to use NETFILE, Netfile Québec, or you are receiving errors regarding your system being unable to access an Internet site or server, you may need to adjust your Firewall and Internet Security settings.

Firewall and virus/spyware-protection programs protect your computer from potential harm by constantly guarding against applications that try to access the Internet or install themselves on your computer.

Because legitimate programs (such as TurboTax) sometimes exhibit some of the same "bad" behavior associated with malicious programs, your security software may prevent harmless programs from accessing the Internet, possibly even preventing them from being installed.

Some firewall and Internet Security software has conflicted with TurboTax in the past, due to this exact behaviour. Let us be clear: TurboTax and all of it's components are 100% safe and should be allowed to install on your system when prompted.

If you are installing TurboTax, and a message pops up asking for permission to continue, or "A program is attempting to access (Internet/Computer application on your system)"say Yes or Allow the process to proceed if the file is associated with TurboTax or the task you were performing
 
Configure your Firewall to Allow TurboTax

To prevent your software from being blocked by a firewall or virus/spyware protector, make sure your security software is always up-to-date. If updating does not resolve the problem, you'll need to temporarily disable the security software to allow legitimate programs to install correctly.

If your firewall software blocks TurboTax's Internet access, you won't be able to:

  • NETFILE your tax return
  • download .pdf files used for printing return, or
  • get the latest program updates.
  • Submit or save the .MRQ file for Québec Provincial Filing
  • Print the TPF.1-U form required when mailing the Québec return

Most firewalls ask you for permission when an "unknown" program attempts to connect to the Internet. In many cases, this connection is decided during the install of TurboTax. If you previously told your firewall to block TurboTax or a file it was attempting to run or install, your firewall will continue to do so until you add it to the list of "allowed" programs.

With some firewalls, you need to add TurboTax ports and addresses to the firewall's list as well. View your firewall's Help for instructions on how to do this, or visit the support site for the Internet Security program you are using.
