When asked, When did you start using this home office for work, do I enter the date of the beginning of the year. For instance, filing 2022 taxes, do I put 01/01/2022?

The date you should enter as the start date of using your home office for work will depend on when you actually started using it for work purposes. If you started using your home office for work on January 1, 2022, then you can enter that date as the start date for your home office use. However, if you started using your home office for work on a different date, then you should enter that specific date instead. It's important to be accurate when providing information for tax purposes to avoid any potential issues or penalties

You should enter the specific date you actually started using your home office.  If you started using your home office in 2016 and have used it consistently every year, that is the date you will enter.  Only enter a 2022 date if you started using it in 2022.
