With the new tax bill, the Tax Cuts and Jobs Act, signed into law in December 2017, there are a few tax changes in 2019. For example, the standard deduction amounts have increased to $12,000 for individuals, $18,000 for heads of household, and $24,000 for married couples filing jointly and surviving spouses. So unless you have large itemized deductions, including property tax mortgage interest, etc, there is a high likelihood that you would be better off claiming the standard deduction.
