Benefits and Working: What Happens When Your Income Goes Up
The fear is real: take a raise, lose Medicaid, end up worse off than before. That can happen — at specific income thresholds for specific programs. But it does not happen as often or as broadly as people assume, and the programs most likely to cause a cliff (childcare subsidies, CHIP) are also the ones with strategies around them. Here is an honest account of what actually changes when income goes up.
SNAP: earnings reduce benefits gradually
SNAP is designed to phase out smoothly as income rises. For every additional dollar of net income (after deductions), your SNAP benefit decreases by 30 cents. This means you always keep 70 cents on the dollar of additional income, even at the SNAP level.
The 20% earned income deduction also reduces your countable income: if you earn $1,000/month more, only $800 counts toward your SNAP calculation. In practice, most working households receive SNAP for several months after starting a job before their income exceeds the gross income limit.
Medicaid: the "unwinding" and coverage transitions
In expansion states, Medicaid covers adults up to 138% FPL. If your income rises above this, you lose Medicaid — but you become eligible for subsidized Marketplace coverage. The transition should be seamless if you act when notified, but there can be a short gap.
In most expansion states, the jump from Medicaid to subsidized Marketplace is manageable because subsidies are generous for income just above the Medicaid cutoff. The benefits cliff for healthcare is most severe in non-expansion states, where people above the Medicaid limit face the full Marketplace premium with limited subsidies at low incomes.
Section 8: you always pay 30% of income
Housing vouchers are designed so you always pay 30% of your household income toward rent. If your income rises, your contribution rises and the voucher covers less — but you do not suddenly lose all housing assistance. This makes Section 8 one of the most work-friendly benefit programs.
You only lose the voucher entirely when your income rises to a point where you can afford market-rate rent without the subsidy, or when you exceed program income limits (typically 80% of area median income).
TANF: work requirements and time limits
TANF is specifically designed as a transitional program. It has a federal lifetime limit of 60 months and work requirements for most adult recipients. The program provides childcare and transportation assistance specifically to help participants enter and retain employment.
TANF benefits reduce as income rises, but the reduction schedule varies by state. Some states taper benefits very aggressively; others provide a modest earnings disregard. TANF transition assistance (childcare subsidies and transportation) can often continue briefly after the family exceeds the cash assistance income limit.
The real math: working almost always pays
The benefits cliff is real — there are specific income ranges where taking a raise costs more than it gains. These are most severe around childcare subsidy income limits and CHIP cutoffs. But the cliff typically occurs at a specific income threshold, not across a broad range of earnings.
The practical advice is: know your income thresholds before accepting a significant raise. The FPL calculator and benefits quiz on this site can help you understand where your current benefits phase out. For most workers earning below 200% FPL, the combination of SNAP, EITC, and potential subsidy eligibility means working more almost always results in higher total income.
