SSDI Trial Work Period: South Dakota Guide

Receiving Social Security Disability Insurance (SSDI) benefits does not mean you can never attempt to work again. The Social Security Administration (SSA) provides a structured pathway called the Trial Work Period (TWP) that allows beneficiaries to test their ability to return to employment without immediately losing their benefits. For South Dakota residents navigating SSDI, understanding this program can mean the difference between financial security and an unexpected benefits gap.

What Is the SSDI Trial Work Period?

The Trial Work Period is a federally administered program that gives SSDI recipients up to nine months to work and earn income while still receiving full disability benefits—regardless of how much they earn. These nine months do not need to be consecutive. They accumulate within a rolling 60-month (five-year) window.

A month counts as a Trial Work Period month in 2024 when your gross earnings exceed $1,110 per month. This threshold adjusts annually for inflation. Once you use all nine TWP months within a 60-month period, the SSA evaluates whether your work qualifies as Substantial Gainful Activity (SGA)—currently $1,550 per month for non-blind individuals and $2,590 for blind individuals in 2024.

If your earnings exceed the SGA threshold after exhausting your TWP months, the SSA may determine you are no longer disabled and terminate your benefits. This makes careful tracking of your work activity essential.

How the Trial Work Period Works in South Dakota

South Dakota has no state-specific SSDI program—disability benefits are administered entirely by the federal SSA through its Sioux Falls and Rapid City field offices. However, South Dakota residents have access to state-level vocational rehabilitation services through South Dakota Vocational Rehabilitation (SDVR), which can work alongside your SSDI benefits to support re-entry into the workforce.

If you live in South Dakota and are considering returning to work, the process generally unfolds as follows:

• Notify your local SSA field office that you have started working, even if your earnings are below the TWP threshold
• Report your monthly gross wages to the SSA consistently—failure to report can result in overpayments and future repayment demands
• Track each month in which your earnings exceed the TWP threshold, as the SSA may not always catch every month immediately
• Contact SDVR at 605-773-3195 for employment support services, job training, or assistive technology that can help you sustain employment

The SSA Sioux Falls office serves the eastern portion of the state, while Rapid City serves the west. Both offices process TWP-related inquiries, though significant decisions—including benefit cessation—are handled at the federal program level.

The Extended Period of Eligibility

After your nine Trial Work Period months are exhausted, a critical 36-month window begins called the Extended Period of Eligibility (EPE). During this phase, you retain the right to receive SSDI benefits for any month in which your earnings fall below the SGA level—without filing a new disability application.

This provision offers meaningful protection for South Dakota workers in industries with variable income, such as agriculture, seasonal tourism, or part-time healthcare work. If your earnings dip below SGA in any month during the EPE, your benefits are reinstated automatically for that month.

Once the 36-month EPE ends, your entitlement to automatic reinstatement expires. If your disability worsens after that point and forces you to stop working, you would need to file for Expedited Reinstatement (EXR)—a separate process that allows former beneficiaries to receive provisional benefits for up to six months while the SSA reviews the reinstatement request.

Reporting Requirements and Common Mistakes

The most serious mistakes SSDI recipients make during the Trial Work Period involve failure to report earnings. The SSA typically discovers unreported work activity through cross-referencing IRS wage data, but this process can take months or years. When the SSA eventually identifies the discrepancy, it issues an overpayment notice requiring repayment of benefits received during ineligible months—sometimes totaling thousands of dollars.

South Dakota beneficiaries should avoid these common errors:

• Assuming self-employment income does not count—it does, based on net earnings after deducting business expenses
• Failing to report work at all because earnings seem "too low to matter"
• Overlooking in-kind compensation, such as housing or food provided by an employer
• Not requesting an Impairment-Related Work Expense (IRWE) deduction, which can reduce countable income by subtracting disability-related work costs like specialized equipment or transportation
• Missing the opportunity to request a Plan to Achieve Self-Support (PASS), which allows you to set aside income or resources for a work goal without affecting benefit calculations

Report earnings proactively by contacting your local SSA field office or using the SSA's my Social Security online portal. Written documentation of every report—date, method, and SSA representative name—can protect you if a dispute arises later.

Protecting Your Benefits During and After the Trial Work Period

Strategic planning before you begin working can significantly reduce your risk of an unexpected benefits interruption. Several steps are worth taking before your first paycheck arrives:

• Request a benefits analysis from a Work Incentive Planning and Assistance (WIPA) counselor—South Dakota's WIPA services are available through community organizations and can be located through the SSA's website
• Document all medical treatment during the work period, because the SSA may initiate a Continuing Disability Review (CDR) triggered by your work activity
• Maintain records of any work accommodations or medical restrictions your employer provides, as these can support ongoing disability claims
• Understand that Medicare coverage continues for at least 93 months after the TWP begins, providing a healthcare safety net even if cash benefits eventually stop

If the SSA sends a cessation notice after your TWP concludes, you have the right to appeal within 10 days of receiving the notice to continue receiving benefits during the appeal process. This right—called appeal with benefit continuation—is time-sensitive and should not be delayed.

An attorney experienced in Social Security disability law can review your earnings history, identify applicable work incentives, and challenge any improper benefit cessation decisions. Given the complexity of TWP rules and the financial stakes involved, professional guidance is often the most cost-effective step you can take.
