Tax filing status married filing separately

When it’s time to file taxes, one of the first decisions married couples make is whether they should choose married filing separately (MFS) or married filing jointly (MFJ). Each couple has its unique financial situation, and choosing wisely not only helps you file your taxes but also reduces your tax liability. Most couples choose to file jointly to claim the benefits and maximize deductions and credits. IRS also allows spouses to file separately, which is a smarter choice under certain conditions.

This guide will walk you through the MFS tax implications, how it works, and its advantages and drawbacks. 

What does Married Filing Separately mean?

Married Filing Separately means each spouse is responsible for reporting their own income, credits, and deductions. The main advantage of choosing to file separately is that one spouse is not legally bound to pay for the other’s tax liabilities, errors, or back taxes. 

However, filing individually can offer some benefits, but it also has its drawbacks.

• You might lose the eligibility to claim credits, such as education credits or dependent care benefits. 
• This can reduce or eliminate your IRS contribution deduction. 
• You cannot claim student loan deductions, which you can if you file jointly. 
• The capital loss deduction limit is $3000 each year that you can claim if you file jointly, which is reduced to $1500 when you file separately. 

The downsides of filing returns separately often lead couples to opt for joint tax filing. 

When should married couples file taxes separately?

Although there are more benefits of filing jointly and some limitations of filing separately, there are certain conditions where choosing MFS is better for your financial needs.

• Protection against spouse’s tax issues 

When you file jointly, you are ultimately responsible for your spouse’s tax debt, back taxes or any other IRS penalties or fines. This means the IRS can seize your assets or tax returns to cover your partner’s debt or student loan payments. However, when you file separately, you are independent of these financial obligations and can protect your finances. This is important for those couples who are not sure about their partner’s tax debts.

• High medical expenses 

The IRS allows you to deduct medical expenses from your income if they exceed 7.5% of your adjusted gross income (AGI). However, if you file jointly, your combined income would be more, and it would be hard to achieve that 7.5% threshold. This means you won’t be able to qualify for a medical tax deduction. However, if you file separately, your income would be low, and you can claim deductions to minimize your taxable income. 

• Separation and divorce situation 

Couples who are living separately or planning for divorce prefer filing separately to keep their finances independent. This will avoid disputes regarding who owes more and who faces the penalties if there is an IRS audit. Moreover, in some states, there are separate return rules to keep their financial document separate in legal divorces.

• Different incomes 

Lower-income spouse qualifies for some deductions and credits, which will phase out if you file your returns jointly. It happens when the other spouse earns more and your combined income falls in the high-income brackets. However, if you file separately, you can still claim those benefits and minimize your tax liability,

What are the separate return rules for married filing separately?

When couples choose to file separately, the IRS applies some rules that can limit what they can claim. Let’s have a look:

1. If one spouse itemizes deductions, the other spouse must also itemize and cannot claim the standard deductions. 
2. Many tax credits and deductions are not allowed when you file separately, for instance:
   • Income tax credit – not allowed
   • Education credit – not allowed
   • Student loan deduction credit – not allowed
   • Child care credit – not allowed
3. IRS limits the IRA contribution deductions. 
4. Loss deduction is reduced to $1500 for each spouse.

Each spouse is responsible for their own tax liabilities, debts, and penalties to stay IRS compliant.
