no, you can't. at least not legally without tax in most countries. 

if you don't want to pay tax, there needs to be no capital gain, so the exchange rate has to be the same. you have to buy and use all the monero for payment, holding zero at any moment. 

 Yes, I was referring to holding stables and swapping that to monero and then spending all of the monero. 

 That only works if your there is a stablecoin that is the same denomination in your company's accounting currency.  

 Right. Makes sense.
