📌 Senior Tax Filing in 2025: How to Claim the $6,000 Senior Deduction Even If Your Spouse Has No ITIN or SSN
Many senior taxpayers face a unique challenge when filing U.S. taxes:
one spouse has a valid Social Security Number (SSN), while the other has neither an SSN nor an ITIN.
After the 2025 tax law changes under the One Big Beautiful Bill Act (OBBBA), this situation does not automatically disqualify seniors from valuable tax benefits.

1️⃣ Can You File MFJ Without Your Spouse’s SSN or ITIN?
The short answer is no.
A joint return (Married Filing Jointly) requires that both spouses have a valid U.S. taxpayer identification number.
The IRS recognizes only SSNs and ITINs for this purpose.
If one spouse has neither, a joint return is not permitted, regardless of how long the couple has lived in the United States.
Filing MFJ without a valid SSN or ITIN for both spouses often leads to refund denials, IRS notices, and potential penalties.
2️⃣ The Only Legal Filing Option When an ITIN Is Not Available
When a spouse cannot obtain an ITIN due to passport or documentation issues, the IRS allows only one compliant filing approach:
- Married Filing Separately (MFS)
- List the spouse as NRA (Nonresident Alien) on the return
While MFS is often viewed as less favorable, it is the only lawful method to preserve deductions when a spouse lacks a tax identification number.
3️⃣ Age 65+: Standard and Additional Senior Deductions
Taxpayers age 65 or older are entitled to an additional standard deduction on top of the regular standard deduction.
This benefit applies even when filing under MFS status.
4️⃣ The New $6,000 Senior Deduction Under OBBBA (2025–2028)
| Eligibility | Taxpayers age 65 or older (per person) |
|---|---|
| Deduction Amount | $6,000 |
| Effective Years | 2025 through 2028 |
| Income Limit | MFS MAGI up to $75,000 (full deduction) |
| Key Feature | Added on top of standard deductions |
5️⃣ Real Example: $33,000 Annual Income Tax Outcome
Gross income: $33,000
– Standard deduction (MFS)
– Additional 65+ deduction
– OBBBA senior deduction ($6,000)
👉 Result: taxable income is minimal or near zero
6️⃣ Can an Adult Child Claim a Parent as a Dependent Instead?
This question comes up frequently, but the answer is generally no.
- Nonresident aliens cannot be claimed as dependents
- A valid SSN or ITIN is required for dependent claims
- Senior deductions apply only to the taxpayer, not dependents
7️⃣ Common Filing Mistakes That Trigger IRS Problems
| Mistake | Risk |
|---|---|
| Using a fake or placeholder SSN/ITIN | Refund denial, penalties |
| Hiding a spouse’s existence | Audit exposure |
| Filing Single or HOH improperly | Back taxes, interest |
| False dependent claims | Credit recapture |
