The standard deduction is a critical component of your federal income tax return, reducing your taxable income and potentially lowering the amount of taxes you owe. For married couples, understanding how the standard deduction differs between “Married Filing Jointly” (MFJ) and “Married Filing Separately” (MFS) is essential for optimizing your tax strategy.
This article explains what the standard deduction is, the differences between these two filing statuses, and how to determine which is the best option for your financial situation.
What Is the Standard Deduction?
The standard deduction is a set dollar amount that taxpayers can subtract from their income before calculating their tax liability. It simplifies the tax process by eliminating the need to itemize deductions, making it a popular choice for many filers.
The IRS adjusts the standard deduction annually to account for inflation. For tax year 2023, the standard deduction amounts are:
- Married Filing Jointly: $27,700
- Married Filing Separately: $13,850
Filing Status and Its Impact on the Standard Deduction
The standard deduction amount you can claim depends significantly on your filing status. Here’s how it breaks down for married taxpayers:
1. Married Filing Jointly (MFJ)
When spouses file a joint tax return, they combine their incomes and deductions. The MFJ standard deduction is significantly higher than the amount for MFS, which can result in substantial tax savings for most couples.
Benefits of MFJ:
- Access to the highest standard deduction amount: $27,700 for 2023.
- Eligibility for valuable tax credits, such as the Earned Income Tax Credit (EITC) and Child Tax Credit (CTC).
- Lower tax rates on higher income due to the broader income tax brackets for joint filers.
Drawbacks of MFJ:
- Both spouses are jointly liable for the accuracy of the return and any taxes owed, which may be a concern in cases of complex or contentious financial situations.
2. Married Filing Separately (MFS)
In this filing status, each spouse files their own tax return, reporting their individual income, deductions, and credits. The standard deduction for MFS is $13,850, half of the MFJ amount.
When to Consider MFS:
- One spouse has significant medical expenses or other itemized deductions that are easier to claim individually.
- You want to separate financial responsibilities for tax purposes, such as in cases of divorce, separation, or contentious finances.
- One spouse has tax liabilities, such as unpaid taxes or child support, that might otherwise impact a joint refund.
Drawbacks of MFS:
- Loss of access to several tax credits, including the Earned Income Tax Credit (EITC) and certain education credits.
- Higher tax rates at lower income thresholds compared to MFJ.
- Both spouses must either itemize or take the standard deduction; if one spouse itemizes, the other cannot claim the standard deduction.
Married Filing Jointly (MFJ) Across Two States
When a married couple lives in one state but works in different states, it introduces complexities to their tax situation, particularly if the two states have differing tax systems. Here’s a breakdown of how this works for couples filing jointly or separately:
When you file jointly, your total income from both spouses is combined and reported on a single federal tax return. For state taxes, the situation depends on the states involved:
- Vancouver, WA (No Income Tax) & Portland, OR (State Income Tax):
- The spouse working in Portland will generally need to file an Oregon non-resident income tax return to report and pay taxes on the income earned in Oregon.
- The spouse working in Washington incurs no state income tax because Washington does not have one.
- The couple will file jointly for their federal taxes, and if Oregon taxes were withheld from the Portland spouse’s paycheck, those taxes will count toward their state tax liability.
- Impact of State Residency Rules:
- Oregon taxes all income earned within its borders, even for non-residents. However, Washington residents working in Oregon are not taxed by Washington since the state doesn’t have income tax.
- Credit for Taxes Paid:
- While Washington doesn’t levy income tax, other states with income taxes may provide a tax credit to offset taxes paid to Oregon. However, credits typically don’t apply here because Washington doesn’t tax residents’ income in the first place.
Married Filing Separately (MFS) Across Two States
If the couple opts to file separately, each spouse reports only their individual income, deductions, and credits. Here’s how that works:
If the couple resides in a community property state (Washington is one), income earned by either spouse may be treated as jointly owned. This means half of each spouse’s income could be attributed to the other for tax purposes, even if filing separately. However, this is generally overridden by Oregon’s separate state tax system for non-residents.
- Oregon Non-Resident Return for the Portland Spouse:
- The spouse working in Oregon will still need to file a non-resident Oregon state tax return to report and pay taxes on income earned there. Filing separately ensures that only their income is subject to Oregon’s tax rates.
- Washington Spouse:
- The spouse working in Washington doesn’t need to file a state return since there is no income tax in Washington. This simplifies their state filing obligations but doesn’t change the federal filing requirements.
- Consider Community Property Rules (if applicable):
- If the couple resides in a community property state (Washington is one), income earned by either spouse may be treated as jointly owned. This means half of each spouse’s income could be attributed to the other for tax purposes, even if filing separately. However, this is generally overridden by Oregon’s separate state tax system for non-residents.
Other Considerations
- Dual State Employment Tax:
- The Portland spouse may have state income tax withheld from their paycheck in Oregon. These withholdings should be monitored to ensure the correct amount is paid throughout the year.
- The Vancouver spouse won’t have state taxes withheld, so there are no additional state requirements for them.
- Planning Opportunities:
- Couples should consider whether filing jointly or separately results in a lower overall tax liability. Tools like tax preparation software or advice from a tax professional can be invaluable.
- The unique tax dynamics of Washington and Oregon present opportunities to optimize financial decisions, such as leveraging Washington’s lack of income tax for savings or strategically timing large purchases to take advantage of Oregon’s lack of sales tax.
Key Takeaway
The choice between filing jointly and separately depends on the couple’s income levels, deductions, and tax liabilities across states. Living in Vancouver and working in Portland introduces cross-state tax considerations, but careful planning and understanding of state-specific rules can help minimize complications and maximize savings.
