Social Security Disability Insurance (SSDI) Trial Work Period (TWP)

The TWP is one of the most valuable work incentives available through SSDI. It gives you the chance to explore employment without the risk of immediately losing your benefits. Understanding how the TWP works can help you protect your benefits while making confident, informed decisions about your future. With the right information, resources, and support, you can navigate the TWP successfully and take meaningful steps toward your employment goals.

Programs and Support:

Practical Steps:

  • To understand the TWP, begin by looking up the current TWP amount on the Social Security website or on the Disability Benefits 101 website.

  • Track your TWP: Your TWP ends when you have used 9 TWP months within a 60-month (5-year) period. Track your monthly work activity and income to know which months count toward your 9-month TWP. If you need help tracking, work with a Work Incentive Planner (WIP) to monitor TWP months or request a Benefits Planning Query (BPQY) report by calling Social Security.

  • Keep a record of pay stubs and wage statements, counting months when you earned over the TWP amount. If you are self-employed, track your income and hours worked.

  • Report to Social Security: Report your wages by the 6th of every month. Keep copies of the wage reports you submit and receipt of submission.

  • Contact a WIP or WIPA counselor for personalized guidance on how work may affect your benefits.

Key Takeaways:

  • The TWP allows you 9 months to test work without losing SSDI cash payments.

  • Your SSDI payment stays the same during all 9 TWP months, no matter how much you earn. SSDI has different rules from SSI; with SSDI, your payment does not decrease when you earn money during TWP.

  • The 9 months do not have to be consecutive; you can use them over a 5-year period (60-month) rolling period.

  • A TWP month counts when you earn over the TWP amount. For self-employed individuals: TWP month also counts if you work more than 80 hours, even if income is lower.

  • Keep detailed records of earnings, pay stubs, and letters from Social Security, and make sure to report your wages on time each month.

  • Get help from a WIP or WIPA project to track TWP months and plan your next steps into the Extended Period of Eligibility (EPE) where different rules apply.

  • Free support is available through WIPA projects, ENs, and DOR to help you make informed choices about your career and benefits.
