One reason you get the following message "Access to the activity statement is not available. Contact the Tax Office"

Is that this option needs to be handled on the ATO Portal, as follows -

Note

- BAS Amendments should work IF the original BAS is in LodgeiT AND there are no values at PAYGI.

- To get a BAS into LodgeiT not originally prepared in LodgeiT use the GST Analyser to 'call' the missing BAS.

- For BAS issue regading "Period", kindly contact ATO, we only serve up what BAS ATO have.

- Note that forms are automatically loaded as soon as they produced, However if you have a new client that has outstanding AS not showing in LodgeIT, just add a new AS form and the software will search for unlodged files.

- If you are not doing tax returns or BAS for a client, you can switch it off in settings and new forms will stop show up
