If you are trying to log in to TaxSlayer ProWeb and are told "Invalid login information, please check username or password", there are a few things you can check before calling support:
Are you at the correct website?
The most common reason this error appears is trying to log in at the wrong website.
If your program doesn't have any special branding, ensure you are at the correct site: online.taxslayerpro.com.
If you are a branded user, be sure you are at your correct branded website.
Have you spelled your username correctly?
Ensure you haven't mistyped your username. Uppercase and lowercase don't matter, but even if it is one character off the website will not recognize it.
Has your username recently changed?
If you have recently gotten a new TaxSlayer Pro account, or branched off from your old tax office to your own tax office, your username more than likely has changed. Ensure you are using your current username when completing the Forgot Password/Password Reset process.
Still having trouble?
If problem persists, select Forgot Username or Forgot Password and follow the prompts.
