Every year, the Social Security Administration adjusts key figures and thresholds that govern how SSDI works. For 2019, several of those numbers shifted in ways that affected applicants, current recipients, and people thinking about returning to work. Here's a clear breakdown of what changed and what stayed the same.
The most broadly felt change in 2019 was the Cost-of-Living Adjustment. SSA announced a 2.8% COLA for 2019 — the largest increase in seven years at that point.
For SSDI recipients, this meant monthly benefit payments automatically increased by 2.8% starting in January 2019. The COLA is calculated based on the Consumer Price Index for Urban Wage Earners and Clerical Workers (CPI-W) and applies uniformly to everyone receiving benefits. No application is required — the adjustment happens automatically.
What a 2.8% increase actually means in dollar terms varies by individual because SSDI benefits are calculated from your personal earnings history, not a flat rate. Someone receiving $1,000 per month saw roughly a $28 increase. Someone receiving $1,800 per month saw roughly a $50 increase. The Social Security Administration sends beneficiaries a notice each December showing their new benefit amount for the coming year.
Substantial Gainful Activity is one of the most important concepts in SSDI. SSA uses your monthly earnings to determine whether you are working at a level that disqualifies you from receiving benefits. If you earn above the SGA threshold, SSA may consider you capable of supporting yourself through work — which affects both new applications and continuing eligibility.
For 2019, the SGA thresholds were:
| Category | 2018 Monthly Limit | 2019 Monthly Limit |
|---|---|---|
| Non-blind individuals | $1,180 | $1,220 |
| Blind individuals | $1,970 | $2,040 |
These limits apply at two critical points: when SSA evaluates a new application and when a current recipient returns to work after their Trial Work Period ends.
The Trial Work Period (TWP) allows SSDI recipients to test their ability to work without immediately losing benefits. SSA uses a separate monthly earnings threshold to define a "trial work month" — any month in which you earn above that amount counts toward your nine allowable trial work months.
For 2019, the trial work month threshold was $880 per month. Once you've used nine trial work months within a rolling 60-month window, SSA evaluates whether your earnings exceed SGA. If they do, your cash benefits can stop.
After the Trial Work Period ends, a 36-month window called the Extended Period of Eligibility (EPE) begins. During this period, you can have benefits reinstated in any month your earnings fall below SGA — without filing a new application.
SSDI recipients receive Medicare coverage after a 24-month waiting period, counted from the date they became entitled to SSDI payments (not the date of their disability onset). This rule did not change in 2019.
For those already enrolled in Medicare, the Part B premium in 2019 was $135.50 per month for most beneficiaries — up from $134 in 2018. Some SSDI recipients who had their Part B premium deducted from their monthly benefit were subject to a "hold harmless" provision that capped how much their premium could increase based on the COLA amount.
If you receive both SSDI and Supplemental Security Income (SSI), you may qualify for Medicaid as well, creating a dual-coverage situation that can significantly reduce out-of-pocket healthcare costs.
While SSDI and SSI are separate programs, some people receive both. SSDI is based on your work history and payroll tax contributions. SSI is a needs-based program for people with limited income and resources, regardless of work history.
For 2019, the federal SSI benefit rate increased to:
These figures represent the federal baseline. Some states add a supplemental payment on top of the federal rate.
Several core SSDI program rules remained consistent:
The 2019 adjustments meant different things to different people depending on where they were in the process.
Someone who applied in 2018 and was still waiting for a decision in 2019 would receive back pay calculated at the rates in effect during each relevant period — a calculation that SSA handles but that depends entirely on their established onset date.
Someone who returned to work during 2019 needed to track whether their earnings crossed either the $880 trial work threshold or the $1,220 SGA threshold, since one triggers a trial work month and the other can end benefit eligibility entirely.
A current recipient simply saw their check increase in January 2019 by 2.8% — but whether that pushed them over an SSI income limit, affected a state supplement, or interacted with other household income is a question with no universal answer.
The numbers are public and consistent. How they apply to any one person's benefit calculation, eligibility, or planning depends on the details of their individual record — details only SSA, and the person themselves, can fully assess.
