Working Part Time on SSDI in South Carolina

Many Social Security Disability Insurance recipients in South Carolina wonder whether they can earn any income without losing their benefits. The short answer is yes — but only within strict limits set by the Social Security Administration. Understanding exactly how part-time work affects your SSDI can mean the difference between keeping your monthly check and triggering an overpayment or termination of benefits.

Substantial Gainful Activity: The Core Rule

The SSA evaluates your ability to work through a standard called Substantial Gainful Activity (SGA). For 2025, the SGA threshold is $1,620 per month for non-blind individuals and $2,700 per month for those who are blind. If your gross earnings consistently exceed these figures, the SSA will generally conclude you are no longer disabled — regardless of your medical condition.

South Carolina residents are subject to the same federal SGA thresholds as claimants in every other state. There is no state-level adjustment. What matters is your monthly gross wages, not your take-home pay after taxes or expenses.

Part-time work that keeps you below the SGA limit is generally permitted. However, you must report all work activity to the SSA promptly. Failing to report earnings — even modest ones — can result in overpayments you will be required to repay, sometimes years after the fact.

The Trial Work Period: A Critical Window

Before the SGA limit even applies, SSDI recipients are entitled to a Trial Work Period (TWP). This provision allows you to test your ability to work for up to nine months (not necessarily consecutive) within a rolling 60-month window without immediately losing benefits, regardless of how much you earn during those months.

In 2025, any month in which you earn more than $1,110 counts as a Trial Work Period month. Once you exhaust all nine TWP months, the SSA evaluates whether your earnings rise to the level of SGA. If they do, your benefits may stop after a brief grace period.

For many South Carolina claimants working part-time retail, restaurant, or service jobs, the TWP provides meaningful flexibility. A worker earning $1,300 per month at a part-time position would be using up TWP months but still receiving full SSDI benefits during that period.

The 36-Month Extended Period of Eligibility

After the Trial Work Period ends, you enter what the SSA calls the Extended Period of Eligibility (EPE), which lasts 36 months. During the EPE, you can still receive SSDI benefits for any month in which your earnings fall below the SGA level — even if you had months above SGA during this window.

This means that if your part-time hours fluctuate — common in seasonal South Carolina industries like tourism, agriculture, and hospitality — you may receive benefits in low-earning months while losing them in higher-earning months. The SSA does not simply terminate your case; instead, benefits are suspended and reinstated based on monthly income.

After the EPE ends, your case closes. If you later become unable to work again, you can request Expedited Reinstatement (EXR) within five years without filing a brand-new application, provided your disability is the same or related to the original condition.

Impairment-Related Work Expenses and How They Help

South Carolina claimants who pay out-of-pocket for disability-related work expenses may be able to deduct those costs when the SSA calculates countable earnings. These are called Impairment-Related Work Expenses (IRWEs).

Examples of deductible IRWEs include:

• Prescription medications taken specifically to manage the disabling condition
• Medically required transportation to and from work
• Adaptive devices, wheelchairs, or prosthetics used at work
• Cost of attendant care needed to perform job duties
• Copays for therapy sessions that allow you to function at work

If your gross earnings are $1,750 per month but you have $200 in documented IRWEs, the SSA calculates your countable earnings as $1,550 — below the SGA threshold. Keeping detailed receipts and documentation is essential. An experienced disability attorney can help you identify every deductible expense you may be overlooking.

Practical Steps for South Carolina Workers on SSDI

If you are currently receiving SSDI and considering part-time employment in South Carolina, taking the right steps from the beginning protects your benefits and avoids costly mistakes.

• Report immediately. Notify the SSA as soon as you begin any work, even if your earnings are minimal. Use the SSA's toll-free number, your local Social Security office, or your online mySocialSecurity account. South Carolina has SSA field offices in Columbia, Charleston, Greenville, Spartanburg, and other cities.
• Track every month's gross earnings separately. The SSA evaluates income on a monthly basis, not annually. Keep pay stubs organized by calendar month.
• Document your IRWEs. Save every receipt related to disability-related work costs. Create a log noting the date, amount, and how the expense relates to your condition.
• Understand your TWP status. Request a Benefits Planning Query (BPQY) from the SSA to find out how many Trial Work Period months you have already used. This is a free document that summarizes your benefit status.
• Contact a WIPA counselor. South Carolina has Work Incentive Planning and Assistance (WIPA) programs funded by the SSA that provide free counseling to beneficiaries exploring work. These counselors can map out exactly how employment will affect your specific situation before you accept a job offer.

One common mistake South Carolina claimants make is waiting until they receive an overpayment notice before addressing a work situation. At that point, the debt may already be thousands of dollars. Proactive communication with the SSA is always the better course of action.

When Work Income Threatens Your Medicare Coverage

SSDI recipients in South Carolina typically become eligible for Medicare after 24 months of receiving disability benefits. Returning to part-time work raises a separate concern: whether Medicare coverage will continue.

Fortunately, federal law provides significant protection. After your Trial Work Period ends, you enter an Extended Period of Medicare Coverage that lasts at least 93 months. During this time, Medicare Part A remains premium-free even if your cash benefits have stopped due to SGA-level earnings. Part B premiums still apply, but coverage itself is not immediately lost.

For South Carolina workers who rely on Medicare to manage chronic conditions — the very conditions that qualify them for SSDI — this protection is significant. Losing affordable health insurance is often a greater concern than the cash benefit itself, and understanding the timeline helps claimants plan accordingly.

If Medicare coverage eventually ends and you cannot afford private insurance, South Carolina's Medicaid program may serve as a bridge. The state administers Medicaid through the South Carolina Department of Health and Human Services, and some former SSDI recipients can qualify for continued Medicaid coverage under specific provisions designed to support working individuals with disabilities.
