Hi there @MathsQ
No, you don't need an ABN to do contract work and most likely won't be entitled to one if it was a once off job. Contractors sometimes provide a statement by supplier instead of an ABN.
Having said that, the fact that you provided your TFN instead of an ABN suggests that it may be personal services income (PSI). I suggest checking if the PSI rules apply.
