Social Security Disability Appeal Deadlines and What Happens If You Miss One

When Social Security denies an SSDI or SSI claim, the denial notice starts a deadline. In most cases, you have a limited window to appeal and missing that window can create major setbacks. The good news is that a missed deadline does not always end the case. Social Security can accept a late appeal in certain situations if you can show “good cause.”

What matters most is timing. The earlier you address the deadline issue, the more options you tend to preserve.

The 60-Day Appeal Deadline

Social Security generally requires an appeal request within 60 days after you receive the notice. 

Social Security also uses a mailing presumption when it counts time. SSA typically assumes you receive a notice five days after it is mailed, unless you can show you received it later. 

Two important takeaways:

• Do not wait to “see if you feel better” or “get everything together first.” Evidence gathering can take time, but preserving the right to appeal often comes first.
• Do not assume the clock starts when you open the envelope. SSA’s time count is tied to the notice date and the five-day mailing presumption. 

What It Means to File “On Time”

An appeal must be requested within the deadline. SSA explains that you can request an appeal online, by mail, or by visiting a local Social Security office. 

If you are close to the deadline, the priority is making sure the appeal request is submitted properly, not just started.

What Happens If You Miss the Deadline

If you do not appeal on time, Social Security may treat the determination as final, and the agency may dismiss the appeal at later stages. 

In practical terms, missing a deadline can lead to consequences like:

• Having to start over with a new application instead of continuing the existing claim
• Losing time in the process, including potential delays in reaching a hearing
• Impacting back pay because filing dates and alleged onset dates can become harder to preserve once a decision becomes final

Not every case plays out the same way, but the risk is real. That is why it is usually better to address the deadline issue immediately than to wait.
