TFN / ABN

TFN vs ABN

A TFN is generally used for employment and personal tax matters. An ABN is used when you earn business income as a sole trader or contractor.

Key points

  • TFN income is usually reported by an employer.
  • ABN income requires your own income and expense records.
  • If you have both, both need to be reviewed for the same income year.

TFN income

TFN income usually refers to salary or wages earned as an employee. Employers report income and tax withheld to the ATO.

ABN income

ABN income is earned through business, contracting, freelancing or platform work. You usually need sales records, invoices and expense records.

When you have both

Many people have salary income and a side business. Keep employee documents and ABN records separate so the tax return can be reviewed clearly.

Summary

Knowing whether your income is TFN, ABN or both helps you prepare the right records.

If you earned both wages and business income

Keep employment records and business records in separate groups so they can be checked clearly. For each job, explain whether you were paid as an employee or invoiced for services. Do not decide solely from the business name on your bank statement.

For wages, provide the Income Statement. For business work, provide invoices or platform statements, payments received and expense records. Flag anything that appears in both sets so the same income is not counted twice.
