To add to my post above, I also ran this question re whether money over a certain amount is subject to tax through AI and it said:

"No, you generally don't pay tax on cash you declare at the airport when entering or leaving a country
(like the US or Canada); you pay duty and taxes only on goods that exceed personal exemptions, but you must declare large amounts of currency (over $10,000 USD/CAD) to avoid seizure and penalties, as declaration is for anti-money laundering, not income tax. The declaration confirms the money isn't from illegal sources, but you must prove its legitimate origin if asked"
