Unfortunately, the NFP self-review return is not available to lodge via digital service providers like LodgeiT.
The only way to lodge it is to use the ATO Online Servies https://www.ato.gov.au/businesses-and-organisations/not-for-profit-organisations/statements-and-returns/how-to-prepare-a-nfp-self-review-return#ato-Howtolodgeyourreturn
