It depends on how much you earn and how it’s taxed. The fasttax.ie tax return system will make this much easier than the Revenue ROS system if you have to file an online Form 11 tax return.

You don’t need to file a tax return if:

  • Your net non-PAYE income is under €5,000,
  • And your gross non-PAYE income is under €30,000,
  • And it’s coded into your PAYE tax (via your tax credits/cut-off point).

In this case, you can report it using Form 12 in myAccount.

You must file a tax return (Form 11) if:

  • Your net non-PAYE income is €5,000 or more, or
  • Your gross non-PAYE income is over €30,000.

If your only non-PAYE income is interest subject to DIRT (like bank interest), you don’t need to file a return.
