Choosing Your Filing Status, and Why It Matters More Than People Think

Filing status looks like an administrative checkbox near the top of the return. It is actually one of the more consequential entries on the whole form — it determines your standard deduction amount, where your bracket thresholds sit, and your eligibility for several credits. And in some situations more than one status is available, which means it is a decision rather than a fact.

The statuses

Single. Unmarried and not qualifying for another status.

Married filing jointly. Married couples filing one combined return. Both spouses are generally jointly responsible for the accuracy of the return and for the tax owed, which is worth understanding rather than glossing over.

Married filing separately. Married couples filing individually. This status carries limitations on several credits and deductions.

Head of household. Available to unmarried taxpayers who maintain a home for a qualifying person and meet a support test. Generally more favorable than single.

Qualifying surviving spouse. Available for a limited period after a spouse's death when there is a dependent child, allowing the more favorable joint rates.

Head of household is the one people miss

It is the most commonly overlooked status, and the requirements are specific enough that people assume they do not qualify when they do — or assume they qualify when they do not.

In broad terms, it generally requires being unmarried or considered unmarried for tax purposes, paying more than half the cost of maintaining a home, and having a qualifying person live with you for more than half the year. There are exceptions and nuances within each of those, particularly around who counts as a qualifying person and what counts toward the cost of maintaining a home.

Because it is more favorable than single, it is worth actually checking against the requirements rather than defaulting.

Married filing separately: rarely better, sometimes right

For most married couples, filing jointly produces a lower combined tax. Filing separately restricts or eliminates a number of credits and deductions, and it can affect the treatment of items like capital losses and IRA contributions.

There are situations where separate returns make sense anyway:

• One spouse has concerns about the accuracy of the other's information, given joint responsibility on a joint return
• Separation or a pending divorce where the practical situation makes a joint return difficult
• Income-driven student loan repayment calculations, where the loan payment consequence can outweigh the tax difference
• Situations involving large medical expenses where the threshold is applied against a lower income
• Liability protection concerns regarding one spouse's tax debts

The right approach when it is genuinely a question is to calculate it both ways. The difference is a number, and guessing at it is unnecessary when it can be computed.

Your status is determined at the end of the year

Marital status for the tax year is generally determined as of the last day of the year. Married on December 31 means married for the whole year for filing purposes; a divorce finalized before year end generally means unmarried for that year.

That timing matters if a marriage or divorce is happening near the end of a year, and it is worth knowing in advance rather than discovering it at filing time.

The credits that depend on status

Several significant credits have eligibility rules or phase-out ranges tied to filing status, and some are unavailable entirely to taxpayers filing separately. Education credits, the earned income credit and various dependent-related benefits all interact with status.

This is a large part of why the choice matters beyond the standard deduction amount.

Changing it after you file

There are rules governing when a filing status can be changed on an amended return, and they differ depending on the direction of the change. Some changes are permitted within the normal amendment window and others are restricted.

Getting it right the first time is considerably simpler than fixing it later.
