This is a permanent Xero platform constraint, not a TinyTax outage. Xero's free developer tier only allows **one active connection** at a time across all apps — if TinyTax was previously connected under a different Xero login or organisation, the slot is taken.
To fix it:
1. In TinyTax, go to **Integrations** and disconnect the existing Xero connection
2. Reconnect using your current Xero credentials
3. Return to the filing form and import again
If you'd rather not reconnect, you can upload your trial balance as a **CSV file** instead — go to the filing form, click **Import Trial Balance**, and choose the CSV option.
