[RobertG]

If you are legally married as of December 31, 2019, you are considered married for tax purposes. You may file either jointly or separately.  

Generally, filing jointly will give you a bigger refund or fewer taxes due. When you file separately, your tax rate is higher and you won't be able to claim:

• Education benefits
• Earned Income Credit (EIC)
• Child and Dependent Care Credit (usually)
• Adoption Credit (usually)
• The same benefit married filing jointly couples get for personal exemptions, itemized deductions, the Child Tax Credit, and capital losses (all of these deductions are reduced by half)
• The standard deduction if your spouse is claiming itemized deductions
