Answer:
$24,400
Explanation:
Assuming that Alan and Donna are married and they decide to file their taxes together, the standard deduction for 2019 taxes was $24,400.
The standard deduction increases if you or your spouse is over 65 years old, or if any of you is blind. The standard deduction generally increases a little bit every year, e.g. during 2018 it was $24,000 and for 2020 it is $24,800.
