IRS PIN

I got an IRS PIN last year March 5, 2021 and used it to file my 2020 tax return at the end of March 2021.

 

I know that the PIN is good for one year, so if I file my 2021 tax return at the end of February 2022 do I need to enter that PIN since it is technically still valid?

 

Do I get a PIN now every year from the IRS?

 

If so, can I opt out of that since it is a pain to deal with this? 

 

thank you 🙂
