How does a long trip abroad change US taxes for a citizen or permanent resident?

I’m a green card holder in the US and a citizen of Brazil.

I work from home in the US for an American company, with an American contract. I don’t report any income in Brazil and don’t receive my salary in a Brazilian bank account.

I would love to go to Brazil for 3 months per year. I understand how the taxation would work in Brazil, but I’m wondering if anything needs to change in the US? Do I need to report this trip when I file my income tax the next year, or can I just consider my taxes the same way as if I was living in the US the whole year? (ps.: I wouldn’t go for more tha 180 days per year)
