how old do you have to be to get given a linking code for the ato

You generally need to be under 18 to be treated as a minor for ATO myGov linking code rules, and ATO community guidance says minors under 18 can’t link unless they can verify two pieces of information from their ATO record.

What that means

• If you’re 18 or older , you can usually link the ATO through myGov by proving your identity in the normal way.

• If you’re under 18 , the ATO says you may still be able to link, but only if you can confirm two details from your ATO record, such as a notice of assessment.

• The linking-code process is about identity verification, not just age alone.

Practical takeaway

If you’re asking whether there’s a minimum age to be given a linking code, the safest answer is: there isn’t a simple age cutoff in the public guidance, but under-18s have extra restrictions and usually need to prove more from their tax record. The ATO’s current guidance says you link through myGov after signing in and confirming your identity details, and if that fails, you may need a linking code.

What to have ready

• TFN.
• Date of birth.
• Bank or tax record details.
• Any ATO notice of assessment or similar record if you are under 18.

If you want, I can turn this into a very short forum-style answer.
