Earned income tax credits can be used as a mechanism for reducing suicide rates among low-income adults, according to new research published in the journal Preventative Medicine.

From the study:

We sought to assess the impact of income support in the form of state earned income tax credit policies on suicide-related behaviors. […] Analyses were performed between April and June 2020. A 10 percentage-point increase in the generosity of state earned income tax credit was associated with lower frequency of non-fatal suicide attempts (prevalence ratio [PR] = 0.96; 95% CI: 0.93–0.99), combined fatal and non-fatal suicide attempts (PR = 0.96; 95% CI: 0.93–0.99), and suicide deaths (PR = 0.99; 95% CI: 0.99–1.00). This translates to 4 fewer suicide attempts per 10,000 population each year. Generous state earned income tax credit policies are associated with reductions in the frequency of most severe suicidal behavior. Income support policies may be one way to reduce suicide attempts and death, especially among low-income adults.
