Tax time for married couples brings a key decision: file jointly or separately? While “Married Filing Separately” (MFS) may seem tempting in specific situations, be cautious – it can lead to substantial tax disadvantages. This article dives into the hidden costs of MFS, helping you compare it to the more standard “Married Filing Jointly” option. By understanding the potential financial impact, you can make an informed decision and maximize your tax savings.
Reasons for Filing MFS

- Separate Filing Preferences: Some individuals simply prefer to file their taxes independently.
Tax Disadvantages of MFS
