Hi, first time question! I just wanted to better understand the ATO's definition of spouse, which says: "Your spouse includes another person who:
you were in a relationship with that was registered under a prescribed state or territory law
although not legally married to you, lived with you on a genuine domestic basis in a relationship as a couple."
I've been seeing my partner for 3 years and we moved in together last November - from my understanding of the above this would make her my spouse (at least since November), as we are living "on a genuine domestic basis in a relationship as a couple". Is that correct?
Finally, as a single I would be liable for the Medicare Levy Surcharge (+$90,000), but as a couple we would not be liable (-$180,000). How does that work if we're considered a couple for only some of the year (e.g. since November)?
