IP ADDRESS CHANGES FOR USERS THAT ARE WHITELISTING GOSYSTEM TAX

If whitelisting is necessary for GoSystem Tax or ONESOURCE Income Tax - Express, we recommend using the URL.

If the only option is to whitelist by IP address, please note the new IP range for the URL.

We recommend strongly that you add the future CIDR range to your current whitelist routing configuration. To avoid uninterrupted access, please complete this prior to October 31, 2021, 6:00 am CST.

Please contact your IT department with this information. If you have any concerns, please contact Support.
