Do I need to report that I paid property tax on a second home on my Federal income tax return 2021? I only reported my primary home.

If you are itemizing deductions you can enter the property tax you paid for your 2nd home.   The deduction is capped at a max of $10K for all the state and local tax you paid.

Not if you don't want to.

You can deduct property taxes on your second home, too. In fact, unlike the mortgage interest rule, you can deduct property taxes paid on any number of homes you own. However, beginning in 2018, the total of all state and local taxes deducted, including property taxes, is limited to $10,000 per tax return.
