Working Part-Time on SSDI in South Dakota

Many Social Security Disability Insurance recipients in South Dakota worry that earning any income will immediately end their benefits. That fear, while understandable, is not entirely accurate. The Social Security Administration has built structured pathways that allow SSDI beneficiaries to test their ability to work without automatically losing their monthly payments. Understanding exactly how these rules operate can protect your benefits while you explore what your body and condition allow.

The Trial Work Period: Your First Nine Months

When you begin working after being approved for SSDI, the SSA gives you a Trial Work Period (TWP) of nine months. During these nine months, you can work and earn any amount without losing your disability benefits, as long as you continue to have a disabling condition.

The nine months do not need to be consecutive. In 2024, any month in which you earn more than $1,110 counts as a trial work month. South Dakota recipients should track these months carefully because once you exhaust all nine, the SSA moves to a different evaluation framework.

During the TWP, you must continue reporting your earnings to the SSA. Failing to do so can result in overpayments that the agency will seek to recover, sometimes aggressively. Keep pay stubs and document every hour worked.

Substantial Gainful Activity and What It Means in South Dakota

After your Trial Work Period ends, the SSA evaluates whether your work rises to the level of Substantial Gainful Activity (SGA). For 2024, the SGA threshold is $1,550 per month for non-blind individuals and $2,590 per month for those who are blind.

If your monthly earnings stay below the SGA limit, you generally keep your SSDI benefits. If you exceed SGA after your TWP is exhausted, the SSA considers you capable of substantial work and will initiate a process to terminate your benefits.

South Dakota does not have a separate state supplement for SSDI the way some states do for SSI, so your income threshold is governed entirely by federal SSA rules. However, South Dakota's lower average wages compared to coastal states can make it somewhat easier for recipients working part-time in local industries—agriculture, retail, healthcare support—to remain below SGA while still contributing to household income.

The 36-Month Extended Period of Eligibility

After your nine trial work months are used up, you enter a 36-month Extended Period of Eligibility (EPE). During this window, your benefits are reinstated automatically in any month your earnings fall below SGA—without filing a new application.

This provision is critically important for South Dakota workers in seasonal industries. A ranch hand or agricultural worker who earns above SGA in summer months but well below the threshold in winter can have benefits turn on and off within the EPE without losing their SSDI status entirely.

Once the 36-month EPE expires, earning above SGA in any month terminates your SSDI benefits, and you would need to file a new application or request Expedited Reinstatement if your condition worsens and prevents substantial work again within five years.

Work Incentives That Protect South Dakota Beneficiaries

The SSA offers several additional work incentives that recipients in South Dakota should know and use:

• Impairment-Related Work Expenses (IRWE): If you pay out-of-pocket for items or services that your disability requires in order to work—adaptive equipment, prescription medications, transportation to medical appointments—the SSA can deduct these costs from your gross earnings before calculating whether you've hit SGA. A recipient with diabetes who needs insulin supplies to function at a part-time job can deduct those costs.
• Subsidies and Special Conditions: If your employer provides extra supervision, makes unusual accommodations, or allows more errors than a typical employee, the SSA may reduce the countable value of your work. This matters for South Dakota recipients working modified roles in small businesses or family operations.
• Unsuccessful Work Attempt: If you try to return to work but must stop or reduce hours within six months due to your medical condition, the SSA may classify it as an unsuccessful work attempt and exclude those months from SGA calculations.
• Plan to Achieve Self-Support (PASS): SSDI recipients who also receive SSI can set aside income or resources toward a work goal—education, vocational training, starting a small business—without those assets counting against their SSI eligibility.

Reporting Requirements and Avoiding Overpayments

South Dakota SSDI recipients must report all work activity to the SSA promptly. The agency requires notification when you start or stop working, when your hours or pay change significantly, and when you incur work-related disability expenses.

Overpayments are one of the most common problems facing SSDI beneficiaries who return to part-time work. If the SSA continues paying you benefits after you should have been stopped, they will bill you for every dollar—sometimes years later. The collections process can include garnishment of future benefits and tax refunds.

To protect yourself:

• Report changes in writing, not just by phone, and keep copies of everything you send.
• Use the SSA's my Social Security online portal to track your reported earnings.
• Request a receipt or confirmation number any time you report by phone.
• Consult with a benefits counselor or attorney before accepting a promotion or raise that might push you above SGA.

South Dakota has Work Incentive Planning and Assistance (WIPA) programs that provide free benefits counseling to SSDI recipients considering a return to work. The South Dakota Blind and Low Vision Services and Vocational Rehabilitation offices can connect you with certified benefits counselors who understand the interaction between SSDI, state programs, and employment.

When Part-Time Work Triggers a Continuing Disability Review

Returning to work—even part-time—can prompt the SSA to schedule a Continuing Disability Review (CDR). During a CDR, the SSA re-evaluates whether your medical condition still meets the definition of disability. If your condition has improved to the point where the SSA believes you can perform substantial work, they may terminate benefits regardless of your current earnings level.

Recipients in South Dakota facing a CDR should gather updated medical records, physician statements confirming functional limitations, and documentation of any treatments or hospitalizations since the original award. If the SSA issues an unfavorable CDR determination, you have the right to appeal and can often continue receiving benefits during the appeals process if you request continuation promptly.

Part-time work in South Dakota is possible while maintaining SSDI, but success depends on knowing the exact rules, documenting everything, and reporting accurately and on time. A misstep at any stage—missing a report, misjudging an SGA calculation, or failing to claim an IRWE—can trigger an overpayment or a wrongful termination that takes months and significant effort to reverse.
