KP-TFND-0002: Object reference not set to an instance of an object. this error message occurred when submitting tax file declaration

Welcome to the Community, morgan-wendy-j1!

The error code you've received KP-TFND-0002 when trying to lodge the tax file declaration means the ATO website being under maintenance. Please try to lodge again your employee's tax file declaration after the ATO maintenance. Here's the link where you can check the information in the ATO website:

https://www.ato.gov.au/General/Online-services/System-Maintenance/

We'd also recommend contacting the ATO directly as they can provide more information on what are your options on how you can lodge the tax file declaration.
