S there an additional deduction for persons over 65?

Yes. 

There's an additional amount to the standard deduction for persons aged 65 or older.

For tax year 2023, standard deductions are:

• $27,700 for married couples whose filing status is “married filing jointly” and surviving spouses;
• $13,850 for singles and married couples whose filing status is “married filing separately”; and
• $20,800 for taxpayers whose filing status is “head of household.”

The additional standard deduction for a blind taxpayer—i.e. a taxpayer whose vision is less than 20/200— and for a taxpayer who's age 65 or older at the end of the year is for each instance:

• $1,500 for married individuals; and
• $1,850 for singles and heads of household.
