Benefit Cliffs: When a Raise Costs You Benefits

1A cliff, a slope and a plateau

Benefits respond to income in three ways. On a slope, each extra dollar earned reduces a benefit by a fraction of a dollar, so the household always comes out ahead. On a plateau, the benefit stays the same for a range of income. On a cliff, the benefit stops at a set income, and a raise of a dollar can cost thousands.

The word cliff is also used for a steep slope, where several benefits phase out at once and the household keeps only a few cents of each additional dollar. The effect is similar: the raise feels like it disappears. It matters because those households are often the ones with the least room for a bad month.

2Where they appear

Some of these are cliffs only in some states. SNAP, for instance, applies a 130 percent gross income test in many states but a higher limit in states that have raised it, and Medicaid for adults varies by whether a state expanded coverage. Our guides to SNAP, Medicare and Medicaid and Marketplace subsidies explain the limits.

3How big is the loss, in dollars

Numbers make the difference between a slope and a cliff visible. In SNAP, a household of three can receive up to $785 a month in 2026. The program counts 80 percent of earned income and subtracts the rest from the maximum at a rate of 30 percent, so a raise of $1 an hour, about $173 a month, cuts the benefit by about $41. That is a slope: of every extra $173 the household earns, it loses about $41 in SNAP and keeps about $132 before taxes.

Marketplace coverage is the cliff most people notice. Above 400 percent of the poverty level the premium tax credit ends. A household whose credit was worth $400 a month would lose $4,800 a year by earning one dollar more than the limit, and would have to earn thousands more to break even. Medicaid has the same shape at 138 percent of the poverty level in states that expanded it. In both cases, the effect depends on your household size and where you live, so the question is whether a particular raise lands near a line.

4Cliffs for older adults and people with disabilities

Medicare has its own cliffs. The income-related premium adjustment steps up at set income levels, and a single dollar over a line can raise the Part B premium by $81.20 a month in 2026, or $974.40 over a year. Our guide to Medicare IRMAA shows the brackets and how to ask for a lower amount after a life-changing event.

Some cliffs are about savings, not income. SSI ends if countable resources pass $2,000 for an individual or $3,000 for a couple, and Medicaid for long-term care has its own asset limits. An ABLE account lets people with disabilities save for disability-related costs without the money counting against SSI, up to a limit, so ask about one before you save in a regular account.

5When several programs overlap

A household that receives more than one benefit can lose a little from each at once. Add the rates for a single parent in the phase-out range as an illustration: roughly 16 to 21 percent from the Earned Income Tax Credit, about 24 percent from SNAP, 7.65 percent in payroll tax and a federal income tax of 10 or 12 percent. Together that is around 58 to 63 percent, so the household may keep only 37 to 42 cents of each extra dollar. It is still a gain, and it is a reason for patience, since the combined rate falls as each benefit runs out.

Child care help is a frequent source of a real cliff. Federal rules let states serve families with income up to 85 percent of state median income, though most states set lower limits, and families often lose the subsidy all at once. Ask your state's child care agency whether it has a phase-out or a grace period.

6How to test a raise before you take it

1. List every benefit your household gets, including health coverage, food, housing, child care and cash help.
2. Find each program's income limit and how it measures income, which may be gross or net, monthly or yearly.
3. Estimate your income after the raise over the year, including overtime and bonuses.
4. Compare total resources, not pay. Add wages and benefits, subtract taxes and any new costs, and compare with now.
5. Ask the caseworker or a counselor before you accept, since some programs have grace periods and some count a raise from the month it starts.

When you call a program, ask the same questions each time: how it measures income, whether gross or net, whether a raise changes the benefit now or only at the next renewal, whether overtime and bonuses count, whether a grace period exists and when the program next checks. Write down the answers and the name of the person who gave them. Our calculators for SNAP, the Earned Income Tax Credit, Medicaid and Marketplace plans can run the numbers for each program. Do the arithmetic once with the raise and once without, and look at the whole household.

7Ways households manage a cliff

• Lower countable income legally. Contributions to a retirement account or a health savings account reduce adjusted gross income, which is what Medicaid and the Marketplace measure.
• Ask about transitional benefits. Some states keep Medicaid, child care or SNAP for a few months after income rises.
• Use work incentives. SSI's earned income rules and Section 1619(b) are designed to keep health coverage as you earn more. See our guide to working on SSI.
• Time the change. A raise at the start of a coverage year or a certification period can matter, so ask when each program checks income.
• Plan for the long run. Many cliffs are narrow, and moving past them often leaves a household better off after a few months.

8Do not refuse a raise by reflex

Most raises leave you ahead, and the long-term gain from higher pay and a stronger work record is large. A cliff is a reason to test a raise first, not a reason to turn it down. If the arithmetic is close, ask a benefits counselor for a free review. Work incentives counselors are available through Social Security's Ticket to Work program, and our guide to Ticket to Work explains how to reach one.

10What changes

Limits change every year and differ by state and household size, and each program decides your case. This is general information and not legal or financial advice. Confirm each limit with the program before you make a decision.
