Can I claim the standard deduction on a pro-rated basis for my wife who passed away on 5-20-17?

Do I claim the entire standard deduction for my wife who passed away on 5-20-2017?

I am sorry for the passing of your wife in 2017.

You can still file as married filing joint with your late spouse for the 2017 tax year if you did not remarry.  No need to prorate the standard deduction. See below for reference
