Lodge BAS, activity statements, and tax returns directly to the ATO — for businesses and tax agents
What it looks like

Every section of the Individual Income Tax Return — income, deductions, offsets, Medicare — with a live tax estimate.
Lodge directly to the Australian Taxation Office from your OneBookPlus dashboard. As a registered Digital Service Provider (DSP), we connect to the ATO via the secure SBR gateway so your business can lodge Activity Statements (BAS), Company Tax Returns (CTR), Trust Tax Returns (TTR), Partnership Tax Returns (PTR), Individual Tax Returns (IITR), TPAR, FBT, and Single Touch Payroll — without leaving the app. All form data is auto-populated from your invoices, expenses, payroll, and GST calculations. Includes mandatory MFA, full audit logging (7-year retention), ABN validation via the Australian Business Register, and TPB-compliant review and verification steps before every submission. For registered tax agents and BAS agents: sign up as a Tax Agency to unlock multi-client management, bulk lodgement, agent declarations, CUREL client registration, and a dedicated agent dashboard. Lodge BAS, tax returns, and TPAR for all your clients from one platform — with your RAN and SSID embedded in every submission.
