Investing while on disability is legal, but the rules split sharply depending on which benefit you receive. Social Security Disability Insurance (SSDI) has no asset limits, so you can hold a brokerage account of any size without touching your monthly check. Supplemental Security Income (SSI) caps countable resources at $2,000 for individuals and $3,000 for couples, which makes ordinary investing risky and pushes most SSI recipients toward ABLE accounts or special needs trusts. Before you open an account, confirm which program you’re on. The answer changes everything that follows.
SSDI: Invest Freely, No Asset Limit
SSDI is funded by the payroll taxes you or your spouse paid while working. Eligibility turns on your work history and medical condition, not your net worth.1Social Security Administration. Work Incentives – General Information A brokerage account worth half a million dollars would not reduce your benefit by a dollar.
Dividends, interest, and capital gains are unearned income. The Social Security Administration only looks at earned income from work when deciding whether you’re engaged in Substantial Gainful Activity (SGA). For 2026, the SGA threshold is $1,690 per month for non-blind individuals and $2,830 per month for those who are statutorily blind.2Social Security Administration. Substantial Gainful Activity Investment profits sit outside that calculation entirely.
Does Active Trading Count as Work?
Almost certainly not. A Social Security Ruling addressing futures trading found that profits from securities transactions are capital gains, not self-employment income under the Social Security Act. Capital gains are excluded from the earned income calculations the SSA uses. Holding index funds and rebalancing occasionally is clearly fine, and even active trading that produces significant profits is treated as capital gains for Social Security purposes. If you formalize the activity as a business, with an LLC and employees, you move into territory where the SSA could view the operation differently.
The Trial Work Period Isn’t Triggered by Investment Income
SSDI includes a Trial Work Period that lets you test working without losing benefits. In 2026, any month you earn more than $1,210 counts as a trial work month.3Social Security Administration. Trial Work Period Investment income does not trigger a trial work month because it isn’t earned. A $10,000 dividend in a single month has zero effect on the count.
SSI: The $2,000 Resource Cap Changes Everything
SSI is a needs-based program. The resource cap is $2,000 for individuals and $3,000 for married couples.4Social Security Administration. SSI Spotlight on Resources These limits have not moved in decades and remain unchanged for 2026.5Social Security Administration. 2026 Cost-of-Living Adjustment (COLA) Fact Sheet The maximum federal SSI payment in 2026 is $994 per month for individuals and $1,491 for couples.6Social Security Administration. SSI Federal Payment Amounts for 2026
The SSA checks your countable resources on the first day of each month. If you’re over the limit on that date, you lose that month’s payment. Sustained months over the limit can lead to termination. That’s why traditional investing in a regular brokerage account is dangerous on SSI: a modest portfolio can put you over.
What Counts, What Doesn’t
The SSA defines resources as things you own that could be converted to cash for food or shelter. Stocks, mutual funds, U.S. savings bonds, bank accounts, and cash all count.7Social Security Administration. SSI Resources – 2025 Edition The agency uses fair market value at the start of each month, so a rising market can push you over $2,000 even if you never touch the account.
Some valuable assets are excluded:
- Your home and the land it sits on, regardless of value
- One vehicle per household, regardless of value
- Personal belongings and household goods
- Burial funds up to $1,500
- ABLE account balances up to $100,000
Special needs trusts, when properly structured, are also excluded. Everything in a standard brokerage or savings account counts dollar for dollar against the $2,000 cap.8Social Security Administration. Exceptions to SSI Income and Resource Limits
If you receive SSI and live with a non-disabled spouse, most of your spouse’s resources are counted as yours through deeming. The combined pile is measured against the $3,000 couple limit. A non-disabled spouse’s pension fund is one notable exception and won’t count against your limit.
How Investment Income Cuts Your SSI Check
Even if your resources stay under $2,000, the income your investments throw off will shrink your monthly SSI payment. Dividends, interest, and capital gains distributions all count as unearned income.9Social Security Administration. SSI Income
The formula: the SSA subtracts a $20 general income exclusion from your unearned income each month, then reduces your SSI check by $1 for every remaining $1. If you receive $120 in dividends, the SSA subtracts $20 and cuts your check by $100. On the 2026 maximum federal benefit of $994, that leaves $894.6Social Security Administration. SSI Federal Payment Amounts for 2026
Here is the trap that catches SSI investors: the stock in your account counts as a resource, and the dividend it pays counts separately as income. You have to stay under the resource cap and manage the income offset at the same time. A portfolio under $2,000 in value can still generate enough income to meaningfully shrink your check.
ABLE Accounts Are the Main Tool for SSI Investors
The Achieving a Better Life Experience (ABLE) Act created tax-advantaged accounts for people with disabilities.10Office of the Law Revision Counsel. 26 USC 529A – Qualified ABLE Programs For SSI recipients who want to invest, this is the primary vehicle. The first $100,000 in an ABLE account is invisible to the SSA’s resource count.11Social Security Administration. Spotlight on Achieving a Better Life Experience (ABLE) Accounts
Who Qualifies in 2026
Starting in 2026, you qualify for an ABLE account if your disability began before age 46. That’s a major expansion from the prior age-26 rule.10Office of the Law Revision Counsel. 26 USC 529A – Qualified ABLE Programs People who became disabled in their 30s and 40s from conditions like multiple sclerosis, traumatic injuries, or progressive illnesses now qualify.
What Happens If You Go Over $100,000
If your ABLE balance climbs high enough to push your countable resources over $2,000, your SSI payments are suspended, but Medicaid coverage continues without interruption and without a time limit.11Social Security Administration. Spotlight on Achieving a Better Life Experience (ABLE) Accounts Bring the balance back down and SSI resumes. That’s a suspension, not a termination, which makes ABLE accounts far more forgiving than a regular brokerage account.
Contributions and Investment Choices
Annual contributions are capped at the federal gift tax annual exclusion, which is $19,000 for 2026.12Internal Revenue Service. IRS Releases Tax Inflation Adjustments for Tax Year 2026 Anyone can contribute on your behalf. If you’re employed and don’t participate in an employer retirement plan, the ABLE to Work provision may let you add additional earned income above the standard limit.
ABLE programs are run by states, and most offer several pre-set portfolios ranging from conservative to aggressive. Contributions go in after-tax, growth is tax-free, and withdrawals are tax-free when spent on qualified disability expenses. Those expenses are defined broadly: housing, transportation, health care, education, assistive technology, and basic living costs. Program fees are generally modest.
Special Needs Trusts for Larger Amounts
ABLE accounts handle most situations, but they have annual contribution limits and a $100,000 SSI exclusion ceiling. A large settlement, inheritance, or back-pay award can exceed what an ABLE account can absorb. Special needs trusts shelter larger sums from SSI resource counting.
A first-party trust (sometimes called a d4A trust) holds your own money. You must be under 65 and disabled, and the trust must be established by you, a parent, grandparent, legal guardian, or a court.13Office of the Law Revision Counsel. 42 USC 1396p – Liens, Adjustments and Recoveries, and Transfers of Assets Properly structured, its assets are excluded from SSI resource counting.14Social Security Administration. SI 01120.203 – Exceptions to Counting Trusts Established on or After 01/01/2000 The trade-off: when you die, the trust must reimburse the state for Medicaid benefits paid on your behalf before anything passes to your beneficiaries.
A third-party trust is funded by someone else, typically a parent leaving an inheritance. Because the money was never yours, there is no Medicaid payback at your death, and the remaining funds pass to the named beneficiaries. Both types can hold stocks, bonds, and real estate without the assets counting against your $2,000 limit. A trustee manages the investments and makes distributions on your behalf, generally avoiding direct payments for food or shelter because those count as in-kind support and reduce SSI. Drafting either type requires an attorney experienced in disability and benefits law; a mistake can make the entire trust countable.
Retirement Accounts Are a Trap for SSI Applicants
Traditional IRAs, Roth IRAs, and 401(k) balances all count as resources for SSI. The SSA treats them like any other financial asset because they can be liquidated, even with taxes and penalties.15Social Security Administration. Defined Contribution Pension Plans and the Supplemental Security Income Program A $5,000 Roth IRA puts you well over the $2,000 cap on its own.
If you’re applying for SSI with an existing retirement account, you may need to spend those funds down before you can qualify. Distributions count as unearned income in the month received and reduce your SSI check through the same dollar-for-dollar formula.9Social Security Administration. SSI Income A non-disabled spouse’s pension fund is excluded from deeming and won’t count against you.
None of this applies to SSDI. SSDI recipients can hold IRAs and 401(k)s of any size.
Reporting and Overpayment Risk
SSI recipients must report any change in resources or income within 10 days after the end of the month it occurred.16Social Security Administration. Understanding Supplemental Security Income Reporting Responsibilities – 2025 Edition Buying stock, receiving a large dividend, or selling investments all qualify. You can report to your local field office or online.
Failing to report is expensive. If the SSA later finds you held excess resources, you owe back every dollar of SSI you received during the months you were over the limit. For SSI overpayments, the agency withholds 10% of your monthly payment until the debt is repaid, and you can request a lower amount, potentially as low as $10 per month.17Social Security Administration. Social Security to Reinstate Overpayment Recovery Rate For SSDI, the default recovery is 100% of your monthly benefit until the overpayment is cleared, though you can negotiate a lower rate.
SSDI recipients have lighter obligations because assets and investment income don’t affect eligibility. The main reporting trigger for SSDI is earned income approaching the SGA threshold. Even so, keeping a clean paper trail of investment activity helps resolve questions during periodic reviews.
The practical takeaway: on SSDI, invest as freely and aggressively as you want. On SSI, treat a regular brokerage account as off-limits and route your investing through an ABLE account, and use a special needs trust for anything larger.
