Does the IRS Recognize Common Law Marriage? Tax Rules Explained

The IRS does recognize common law marriage for federal tax purposes—but only if the couple lives in a state that legally recognizes it and meets that state’s specific requirements. If you qualify, you can file joint tax returns, claim spousal exemptions, and access federal benefits like Social Security survivor payments.

Federal Recognition Under the Internal Revenue Code (IRC)

The IRS follows federal tax law, which defers to state law for marital status determinations. Under Revenue Ruling 58-66, the IRS treats a common law marriage as valid if:

1. The couple resides in a state that legally recognizes common law marriage.
2. The couple meets that state’s specific requirements for establishing a common law marriage.

The IRS does not have its own definition of marriage. Instead, it relies on state law (as outlined in 5 U.S.C. § 7701(a)(17) and Treasury Regulation § 301.7701-18).

State-Specific Requirements

Common law marriage is not recognized in all 50 states. As of 2024, only 8 states and the District of Columbia legally recognize it:

Note: Utah recognizes common law marriage only if validated by a court order (Utah Code § 30-1-4.5).

Federal Agencies That Follow IRS Recognition

If the IRS recognizes your common law marriage, other federal agencies typically do as well, including:

• Social Security Administration (SSA) – For survivor benefits (SSA Program Operations Manual System (POMS) GN 00305.075).
• Department of Veterans Affairs (VA) – For spousal benefits.
• Office of Personnel Management (OPM) – For federal employee benefits.

1. Confirm Your State Recognizes Common Law Marriage

• Check the table above or consult your state’s family law statutes.
• If you moved from a recognizing state to a non-recognizing state, your marriage remains valid under the "place of celebration" rule (Restatement (Second) of Conflict of Laws § 283).

2. Gather Evidence of Your Common Law Marriage

The IRS may request documentation proving:

• Mutual agreement to be married (e.g., joint bank accounts, shared lease/mortgage).
• Cohabitation (e.g., utility bills, mail addressed to both partners at the same address).
• Public representation as married (e.g., joint tax returns, insurance policies listing each other as spouses, affidavits from friends/family).

Pro Tip: If you filed taxes as "single" in the past but now claim common law marriage, you may need to amend prior returns (IRS Form 1040-X).

3. File Your Taxes as "Married Filing Jointly" or "Married Filing Separately"

• Use IRS Form 1040 and check the "Married Filing Jointly" or "Married Filing Separately" box.
• If the IRS questions your status, you may need to submit Form 8832 (Entity Classification Election) or a written statement explaining your common law marriage.

4. Claim Spousal Benefits (If Applicable)

• Social Security: File Form SSA-2 (Application for Wife’s or Husband’s Insurance Benefits).
• VA Benefits: Submit VA Form 21-526EZ (Application for Disability Compensation).
• Federal Employee Benefits: Contact the Office of Personnel Management (OPM).

5. Respond to IRS Inquiries (If Audited)

• The IRS may request additional proof (e.g., affidavits, joint financial records).
• If denied, you can appeal through the IRS Office of Appeals or petition the U.S. Tax Court.

Mistake #1: Assuming All States Recognize Common Law Marriage

• Consequence: If you file as "married" in a non-recognizing state, the IRS may reject your return and impose penalties for incorrect filing status.
• Solution: Check your state’s laws before filing.

Mistake #2: Failing to Document the Relationship

• Consequence: Without proof (e.g., joint leases, affidavits), the IRS may disallow spousal exemptions and require repayment of taxes owed.
• Solution: Keep dated records (e.g., shared bills, insurance policies, social media posts).

Mistake #3: Moving to a Non-Recognizing State Without Legal Validation

• Consequence: Some states (e.g., Pennsylvania, which abolished common law marriage in 2005) do not recognize new common law marriages but may honor pre-existing ones.
• Solution: If you move, consult a family law attorney to formalize your marriage.

Mistake #4: Filing as "Single" After Establishing Common Law Marriage

• Consequence: The IRS may audit prior returns and assess back taxes + penalties (20% accuracy-related penalty under IRC § 6662).
• Solution: Amend past returns (Form 1040-X) if you mistakenly filed as single.

Exception: Same-Sex Common Law Marriage

• The IRS recognizes same-sex common law marriages if the state where the marriage was established allows it (post-Obergefell v. Hodges, 2015).

### Can I file taxes as married if my state doesn’t recognize common law marriage?

No. The IRS only recognizes common law marriage if your state of residence legally recognizes it. If you live in a non-recognizing state (e.g., California, Florida), you cannot file as married unless you have a formal marriage license.

### What happens if the IRS denies my common law marriage claim?

If the IRS rejects your filing status, you’ll receive a notice (CP2000 or Letter 525) explaining the issue. You can:

1. Provide additional evidence (e.g., affidavits, joint financial records).
2. File an amended return (Form 1040-X) if you mistakenly claimed the wrong status.
3. Appeal through the IRS Office of Appeals or petition the U.S. Tax Court.

### How long do I have to live together for common law marriage?

There is no minimum time requirement—what matters is mutual intent + public representation. Some states (e.g., Texas) require holding out as married for a "reasonable" period, while others (e.g., Colorado) have no set duration.

### Can I claim my common law spouse as a dependent?

Yes, if you meet the IRS dependency tests (IRS Publication 501):

• They must be a U.S. citizen, resident alien, or national.
• They must not file a joint return (unless only for a refund).
• They must have less than $4,700 in gross income (2024).
• You must provide more than half their support.

### Does Social Security recognize common law marriage?

Yes, but you must prove it to the SSA with:

• A signed statement from both partners.
• Affidavits from friends/family.
• Joint financial records (e.g., bank accounts, leases).

### What if my partner dies—can I still claim common law marriage?

Yes, but you must prove the marriage existed before death. The IRS and SSA may require:

• Affidavits from witnesses.
• Joint financial documents (e.g., shared bills, insurance policies).
• A court order (in some states, like Utah).
