What changed about SSDI taxes in 2014

The tax treatment of Social Security Disability Insurance (SSDI) in 2014 followed the same rules that had been in place since 1984. Whether your SSDI payments were taxable depended on your total income for the year — not on SSDI itself being inherently taxable or tax-free. The IRS looked at a calculation called combined income, which added your adjusted gross income, nontaxable interest, and half your SSDI benefits together. If that number exceeded a certain threshold, a portion of your benefits became taxable.

Nothing specific to 2014 changed these rules. The thresholds stayed the same as they had been for decades: $25,000 for single filers and $32,000 for married couples filing jointly. If you filed taxes in 2014 and received SSDI, you would have used these same thresholds to determine whether you owed tax on any portion of your benefits.

Key Takeaways

  • In 2014, SSDI became taxable only if your combined income (adjusted gross income plus half your SSDI) exceeded $25,000 for single filers or $32,000 for married couples filing jointly.
  • The tax thresholds in 2014 were the same as they had been since 1984 and have not changed since.
  • If you were below the threshold, none of your SSDI was taxable; if you were above it, the IRS used a formula to calculate what portion was taxable.
  • The amount of SSDI that could be taxed was capped at 85 percent of your benefits, even if your income was very high.

How the 2014 combined income calculation worked

To find out whether your SSDI was taxable in 2014, you had to calculate your combined income. Start with your adjusted gross income — the number from your tax return before you claimed the standard deduction or itemized deductions. Then add any nontaxable interest you received (such as interest from municipal bonds). Finally, add half of your total SSDI benefits for the year.

Once you had that combined income number, you compared it to the threshold for your filing status. For single filers, the threshold was $25,000. For married couples filing jointly, it was $32,000. For married couples filing separately, the threshold was $0 — meaning any combined income at all would trigger taxation of at least some benefits.

If your combined income was below the threshold, you owed no tax on your SSDI. If it was above the threshold, you moved to the next step: calculating how much of your benefits was actually taxable using a two-tier formula.

The two-tier formula for taxable SSDI in 2014

If your combined income exceeded the threshold, the IRS did not tax all your SSDI. Instead, it used a two-tier system that determined what portion was taxable.

Tier 1: You took the amount by which your combined income exceeded the threshold. You then took the lesser of that amount or half your total SSDI benefits. This was your Tier 1 taxable amount, and up to 50 percent of it was taxable.

Tier 2: If your combined income was high enough, you calculated a second amount. You took your combined income minus $34,000 (for single filers) or $44,000 (for married filing jointly). You then took the lesser of that amount or 85 percent of your total SSDI benefits. Up to 85 percent of this Tier 2 amount was taxable.

The total taxable SSDI was the sum of what you owed from Tier 1 and Tier 2, but it could never exceed 85 percent of your total benefits. This cap meant that even people with very high incomes could not have more than 85 percent of their SSDI taxed.

Who actually paid tax on SSDI in 2014

Most people receiving SSDI in 2014 did not pay tax on their benefits. The thresholds of $25,000 and $32,000 were relatively low, but many SSDI recipients had income below those levels. However, if you had other income — from work, pensions, investments, or a spouse's income — you could easily cross the threshold.

The people most likely to owe tax on SSDI in 2014 were those who continued to work while receiving benefits, those with substantial investment income, or married couples where one spouse had significant earnings. A person earning $20,000 from part-time work plus $15,000 in SSDI would have a combined income of $22,500 plus half their SSDI, which would likely exceed the $25,000 threshold.

How to report SSDI on your 2014 tax return

If you received SSDI in 2014, the Social Security Administration sent you a form SSA-1099 by January 31, 2015, showing your total benefits for the year. You used this form to calculate your combined income and determine whether any of your benefits were taxable.

You reported your SSDI on line 5b of Form 1040 (the main federal income tax form). If none of your benefits were taxable, you entered the full amount on line 5b and put zero on line 5c (taxable social security benefits). If some were taxable, you entered the full amount on line 5b and the taxable portion on line 5c. The taxable portion then flowed into your adjusted gross income calculation.

Many people used the IRS worksheet in Publication 915 to calculate the taxable portion. If you worked with a tax preparer in 2014, they would have done this calculation for you using the same thresholds and formulas.

State taxes and SSDI in 2014

Federal tax rules and state tax rules are separate. In 2014, most states did not tax SSDI at all, regardless of income level. However, a handful of states — including Colorado, Connecticut, Kansas, Minnesota, Missouri, Montana, Nebraska, New Mexico, Rhode Island, Utah, and Vermont — did tax SSDI under certain circumstances.

State tax treatment varied. Some states used the same federal thresholds; others had their own rules. If you lived in one of these states and received SSDI in 2014, you would have needed to check your state's specific rules or work with a tax preparer familiar with your state's law. The form SSA-1099 you received did not tell you whether your state would tax your benefits — that was a separate calculation based on your state's law.

Why the 2014 thresholds have not changed since 1984

The $25,000 and $32,000 thresholds were set in 1984 when Congress first made SSDI taxable. These thresholds have never been adjusted for inflation. This means that over the decades, more and more SSDI recipients have crossed the threshold and owed tax on their benefits, even though their real income (adjusted for inflation) may not have changed.

A person with $25,000 in combined income in 1984 had significantly more purchasing power than someone with $25,000 in 2014. Because the thresholds stayed frozen, the tax hit more people over time. This is sometimes called "bracket creep," and it has been a source of concern for disability advocates, though Congress has not changed the thresholds.

Frequently Asked Questions

If I received SSDI in 2014 and did not file taxes, do I owe back taxes now?

That depends on whether you were required to file. If your combined income was below the filing threshold for your age and status, you were not required to file even if some SSDI was technically taxable. However, if you had other income that pushed you above the filing threshold, you should have filed. Consult a tax professional or contact the IRS to determine your specific situation.

Does receiving SSDI in 2014 affect my Medicare premiums?

SSDI itself does not directly affect Medicare premiums, but your income does. If your modified adjusted gross income in 2014 was above certain thresholds, you paid higher premiums for Medicare Part B and Part D. This is separate from whether your SSDI was taxable for income tax purposes.

What if I had very little income besides SSDI in 2014?

If your only income in 2014 was SSDI and it was below $25,000 (for single filers), none of your benefits were taxable. You likely did not need to file a federal tax return unless you had other income sources or were claimed as a dependent.

Can I amend my 2014 tax return if I made a mistake with SSDI?

Yes. You can file an amended return using Form 1040-X. You have generally three years from the original due date to amend, though special circumstances may extend that. If you believe you made an error on your 2014 return involving SSDI, a tax professional can help you file the amendment.
