SSDI Trial Work Period: Colorado Guide

Returning to work while receiving Social Security Disability Insurance (SSDI) benefits is a goal many Colorado recipients share, but the fear of losing benefits stops most from even trying. The Trial Work Period (TWP) exists precisely to remove that barrier. Understanding how it functions—and how to use it strategically—can mean the difference between a successful return to employment and an unnecessary gap in income protection.

What Is the SSDI Trial Work Period?

The Social Security Administration (SSA) allows SSDI recipients to test their ability to work without immediately losing benefits. This window is called the Trial Work Period. During the TWP, you can earn any amount of money from work and still receive your full SSDI monthly payment, provided you continue to meet the medical definition of disability.

The TWP consists of nine months within a rolling 60-month (five-year) window. These nine months do not need to be consecutive. Once you accumulate nine Trial Work months, the TWP ends and the SSA evaluates whether your work activity constitutes Substantial Gainful Activity (SGA).

For 2024, the monthly earnings threshold that triggers a Trial Work month is $1,110. If you earn more than this amount in any calendar month, that month counts as one of your nine Trial Work months. For self-employed Colorado residents, the SSA looks at both earnings and hours worked—services rendered for more than 80 hours in a month can also trigger a Trial Work month regardless of net income.

How the Trial Work Period Operates in Colorado

Colorado does not administer SSDI independently—it is a federal program managed through the SSA's Denver regional office and local field offices in cities like Colorado Springs, Pueblo, Fort Collins, and Grand Junction. However, several Colorado-specific factors influence how TWP situations play out in practice.

Colorado's cost of living, particularly along the Front Range, often pushes part-time wages above the monthly TWP threshold quickly. A Colorado resident working even a modest part-time retail or service job may inadvertently trigger Trial Work months without realizing it. Tracking your gross monthly earnings carefully—not net pay—is essential, since the SSA uses gross wages.

Additionally, Colorado operates Vocational Rehabilitation (VR) services through the Colorado Division of Vocational Rehabilitation (DVR). Participating in DVR-sponsored work training or supported employment programs can interact with your SSDI benefits in specific ways. Certain subsidized wages or impairment-related work expenses (IRWEs) recognized under Colorado DVR programs may be deducted before the SSA calculates whether your earnings meet the SGA threshold—this can extend how long you retain benefits during and after the TWP.

What Happens After the Trial Work Period Ends

Once you have used all nine Trial Work months, the SSA enters a second phase called the Extended Period of Eligibility (EPE), which lasts 36 months. During the EPE, you receive SSDI benefits for every month your earnings fall below the SGA level. For 2024, the SGA threshold is $1,550 per month for non-blind recipients and $2,590 per month for blind recipients.

If your earnings exceed SGA during the EPE, the SSA will stop your benefits for that month. However, you remain in the EPE window, meaning if your earnings drop below SGA again—due to a layoff, medical relapse, or reduced hours—benefits can be reinstated without filing a new application. This flexibility is one of the most underutilized protections in the SSDI system.

After the EPE concludes, if you are still working above SGA, your SSDI case closes. At that point, if your condition worsens and you must stop working again within five years, you may qualify for Expedited Reinstatement (EXR)—allowing benefits to resume while the SSA reviews your medical condition, without requiring a completely new application.

Common Mistakes Colorado SSDI Recipients Make During the TWP

Several errors consistently create problems for SSDI recipients attempting to return to work:

• Failing to report work activity promptly. The SSA requires you to report any work when you start a job, when your duties or pay change, and if you stop working. Colorado recipients should report changes to their local SSA field office in writing and keep copies of all correspondence.
• Forgetting to track Trial Work months. Because the nine months occur within a 60-month rolling window, recipients often lose count. Requesting your earnings record from the SSA annually helps verify which months have been counted.
• Overlooking deductible work expenses. Impairment-Related Work Expenses—such as medication, adaptive equipment, or transportation costs directly related to your disability—can be subtracted from gross earnings before the SGA calculation. Many Colorado recipients miss significant deductions simply because they were never told about them.
• Assuming the TWP applies to SSI. The Trial Work Period is an SSDI-only provision. If you receive Supplemental Security Income (SSI) instead of or in addition to SSDI, different work incentive rules apply, including the $1 for $2 benefit reduction rule rather than a TWP structure.
• Discontinuing medical treatment during trial work. Returning to work does not reduce the SSA's obligation to periodically review your medical condition. Stopping treatment during this period can create records suggesting your condition has resolved, which may jeopardize your benefits.

Protecting Your Benefits While Testing Your Ability to Work

Strategic use of the Trial Work Period requires documentation and proactive communication with the SSA. Keep detailed records of every paycheck, your hours worked, and any disability-related expenses incurred to perform your job. If you work for yourself anywhere in Colorado—whether as a contractor in Denver's tech sector or as an agricultural worker in the San Luis Valley—document your hours and business expenses meticulously, as self-employment income calculations differ from traditional wages.

Consider requesting a Benefits Planning Query (BPQY) from the SSA before beginning work. This document summarizes your current benefit status, Medicare entitlement, and how many Trial Work months you have already used. Colorado also has Work Incentive Planning and Assistance (WIPA) counselors—federally funded advisors who provide free guidance on how returning to work will affect your specific benefit package. The Rocky Mountain ADA Center and several Colorado nonprofit legal aid organizations connect SSDI recipients with these services at no cost.

If the SSA determines that your work exceeded SGA and proposes to terminate your benefits, you have the right to appeal. Filing a timely appeal—generally within 60 days of receiving notice—allows you to potentially continue receiving benefits while your case is reviewed. An attorney familiar with SSA administrative hearings can evaluate whether your earnings were properly calculated, whether applicable work incentives were applied, and whether a vocational or medical argument supports your continued entitlement.

The Trial Work Period is a genuine opportunity. Used carefully and with proper documentation, it allows Colorado SSDI recipients to explore employment without gambling with their financial security. The rules are complex but navigable with the right guidance.
