TFN processing time
The ATO says to allow up to 28 days after your identity is verified for your TFN to arrive by post. Delays usually come from incomplete identity checks or a mismatched address. While waiting, you can still start work — give your employer a TFN declaration noting you've applied.

What slows it down
- Identity interview not completed.
- Address can't receive post.
- Name differences between documents.
While you wait
- Tell your employer you've applied (you have a set period to provide it before higher withholding applies).
- Don't apply twice — it can delay things.
