You're seeing Error: '400: BadRequest - Payload issue. Contact support because you're trying to lodge a 2020 individual tax return for a part-year resident. The tax return you're trying to lodge will be stuck on Transmitting status.
If there are any other returns that are stuck on Transmitting status and are not for a part-year resident, see KB Troubleshooting returns stuck in transmitting or transmitted
Why are returns with a part-year resident stuck on transmitting status?
In our recent interactions with the ATO, we’ve identified an issue for any lodged 2020 Individual returns where the taxpayer is a part-year resident. The value at Number of months eligible for tax-free threshold field is not being sent to the ATO.
This has resulted in ATO incorrectly calculating tax payable on the Notice of Assessment (NOA) for the affected taxpayers.
We've resolved this issue in hotfix 56036984.
We recommend installing hotfix 56036984 before lodging any 2020 individual returns for a part-year resident. Otherwise lodging will fail with this error.
We apologise for the inconvenience this is caused.
