Im married and my spouse works..I'll be retiring at the end of 2025..what's the best filing status and who should claim who?

A spouse cannot ever be claimed as a dependent.   File a joint tax return with your spouse.  When you file a joint return you get the highest standard deduction--which makes less of your income taxable---for a married couple on a 2025 tax return your standard deduction for 2025 will be $30,000 + additional $1600 for each spouse 65 or older.
