Advantages of filing jointly

There are many advantages to filing a joint tax return with your spouse. The IRS gives joint filers one of the largest standard deductions each year, allowing them to deduct a significant amount of their income immediately.

Joint filers mostly receive higher income thresholds for certain taxes and deductions—this means they can earn a larger amount of income and potentially qualify for certain tax breaks.

Consequences of filing your tax returns separately

On the other hand, couples who file separately receive few tax considerations. Separate tax returns may give you a higher tax with a higher tax rate. The standard deduction for separate filers is far lower than that offered to joint filers.

When you might file separately

In rare situations, filing separately may help you save on your tax return.

  • For example, if you or your spouse has a large amount of out-of-pocket medical expenses to claim and since the IRS only allows you to deduct the amount of these costs that exceed 7.5% of your adjusted gross income (AGI) in 2021, it can be difficult to claim most of your expenses if you and your spouse have a high AGI.
    • For example, if you have $10,000 in medical expenses and made $50,000. That would meet the 7.5% threshold ($10,000 ÷ $50,000 = 20% of your income).
    • Whereas, if together you make $135,000, this would disqualify you from claiming these medical expenses ($10,000 ÷ $135,000 = 7.4% of your income).
  • Filing separate returns in such a situation may be beneficial if it allows you to claim more of your available medical deductions by applying the threshold to only one of your incomes.
