Your company doesn’t move with you, and the sale order is everything

The founder’s mistake is assuming the business is portable. It isn’t. A company’s tax residency follows its central management and control, where the real, high-level decisions are actually made. If you’re the sole director and you start making those decisions from Lisbon or Dubai, your Pty Ltd can quietly become a tax resident of two countries at once. Under the modern treaty rules there’s no automatic tie-breaker to sort that out; you need the two tax offices to agree, and until they do, most treaty relief simply isn’t available.

That dual residency drags a chain of problems behind it: a CGT event on the company’s non-TAP assets when it becomes non-resident, disrupted franking, and (if you’re doing the work personally abroad while your customers are in Australia) a permanent-establishment question about where the profit is really earned.

And then there’s the sale. If you’re selling the business anywhere near your departure, the order of operations can be worth six figures. Sell while you’re still a resident and you may access the small business CGT concessions, the 15-year exemption, the 50% active asset reduction, the retirement exemption. Sell after you’ve left and those concessions are impaired or gone, and you’re into a non-resident CGT position. Occasionally leaving first genuinely wins, if the concessions don’t apply and your destination taxes gains at zero, but you only know which case you’re in by modelling both.

Get the residency of the entity settled, model the sale both ways, and sequence the whole thing before you book a flight.
