Hi @TRangitaawa,

There's no 'best' ABN. There's just one ABN for your business activities, regardless of how many jobs or platforms you work with. If you're operating as a business, you'd use the same ABN across all your online data jobs and trading activities.

Before you apply for an ABN, you'll need to work out if you're entitled to one and decide on your business structure. Not everyone needs an ABN, you're only entitled to one if you're running a business or certain other enterprises. You can operate as a sole trader, partnership, company, or trust, and your choice affects your tax, super, and legal responsibilities.

If you do operate as a sole trader with an ABN, you'd declare all your income from these different jobs on your individual tax return. For example, if you run multiple online activities, you'd report all that income together. However, if you choose a different business structure like a company or trust, different rules apply.

Getting an ABN is free, and it can make running your business easier by helping you keep track of transactions and preventing tax being withheld from payments. It's worth checking if you're entitled to have an ABN before you apply and considering which business structure suits your situation.
