The federal government redistributes income by collecting revenue in rough proportion to what people can pay and then sending it back out through cash benefits, refundable tax credits, in-kind programs like health coverage and food assistance, and publicly funded services open to everyone. The result is a narrower gap between what households earn in the private market and what they actually have available to spend.
There is no single lever behind this. It is a stack of tax rules and spending programs, each doing part of the work.
How the Tax Side Pulls More From Higher Earners
The federal income tax is the government’s main tool for collecting revenue in line with ability to pay. Under 26 U.S.C. § 1, taxable income is split into brackets, each taxed at a progressively higher rate. The current structure runs from 10 percent on the lowest slice of income to 37 percent on income above the top threshold.1Office of the Law Revision Counsel. 26 USC 1 – Tax Imposed Only the dollars inside a given bracket are taxed at that bracket’s rate, so crossing into the 24 percent bracket does not mean paying 24 percent on everything you earned.
Investment profits sit in a separate lane. When you sell an asset like stock or real estate for more than you paid, the gain is taxed based on how long you held it and your overall income. Long-term gains, from assets held more than a year, are taxed at 0, 15, or 20 percent depending on taxable income, while short-term gains are taxed as ordinary income.2Internal Revenue Service. Topic No. 409, Capital Gains and Losses Taxing investment growth separately captures a share of wealth appreciation that income tax alone would miss.
The estate tax handles the transfer of wealth between generations. Under 26 U.S.C. § 2001, tax is imposed on the total value of a deceased person’s estate before it passes to heirs.3Office of the Law Revision Counsel. 26 USC 2001 – Imposition and Rate of Tax For 2026, the first $15 million of an estate’s value is exempt, so only estates above that threshold owe anything.4Internal Revenue Service. Whats New – Estate and Gift Tax The top rate on value above the exemption is 40 percent, and married couples can combine their exemptions to shelter up to $30 million. It reaches only a small share of estates, but it keeps the largest fortunes from moving across generations fully intact.
Cash Paid Directly to Households
A large share of what the government collects goes straight back out as regular payments to individuals who meet specific criteria.
Social Security
Social Security is the single largest redistribution program in the federal budget. It sends monthly payments to retirees, survivors of deceased workers, and people with disabilities, funded by a payroll tax split between employers and employees and paid out to current beneficiaries.5Office of the Law Revision Counsel. 42 USC Chapter 7 – Social Security The benefit formula tracks each worker’s lifetime earnings but is weighted so that a higher share of pre-retirement income is replaced for lower earners. Someone with modest career wages might see Social Security replace roughly 55 percent of prior income, while a high earner might see about 25 percent replaced. Everyone who pays in receives benefits, but the tilt inside the formula makes the transfer progressive.
Supplemental Security Income
Supplemental Security Income (SSI) pays monthly cash benefits to elderly, blind, or disabled people with very limited income and resources. It is funded from general tax revenue rather than payroll taxes, and no work history is required. For 2026, the federal payment is $994 per month for an individual and $1,491 per month for a couple, and some states add a supplement on top.6Social Security Administration. 2026 Cost-of-Living Adjustment (COLA) Fact Sheet Countable resources cannot exceed $2,000 for an individual or $3,000 for a couple, limits that have not been updated in decades.
Unemployment Insurance
Unemployment insurance provides temporary cash payments to workers who lose their jobs through no fault of their own, generally through layoffs or business closures rather than resignations or firings for cause. The program is funded primarily through employer-paid taxes and administered by the states under federal rules.7U.S. Department of Labor. How Do I File for Unemployment Insurance Benefits are calculated as a percentage of prior earnings, subject to a state-set maximum, and in most states run up to 26 weeks.8Department of Labor (Doleta). Fact Sheet – Unemployment Insurance
Temporary Assistance for Needy Families
Temporary Assistance for Needy Families (TANF) provides cash assistance to low-income families with children. It runs as a federal block grant of $16.6 billion per year distributed to states, which design their own programs within federal guidelines.9Administration for Children & Families. About Temporary Assistance for Needy Families Monthly payments for a family of three range from roughly $300 to more than $1,100 depending on the state. Recipients generally have to take part in work-related activities, and federal law caps federally funded assistance at five years over a lifetime.10Office of the Assistant Secretary for Planning and Evaluation. Aid to Families with Dependent Children and Temporary Assistance for Needy Families – Overview
Cash Delivered Through the Tax Return
Some of the government’s most direct redistribution happens through the tax code. Refundable credits can pay out more than a household owes in taxes, so the filer ends up with a check from the government rather than a bill.
Earned Income Tax Credit
The Earned Income Tax Credit (EITC) is built to reward work at lower income levels. It phases in as earnings rise, reaches a maximum, and then phases out. For the 2025 tax year (filed in early 2026), the maximum credit ranges from about $664 for a worker with no children to roughly $8,231 for a family with three or more children. Because the credit is refundable, a family that owes little or no federal income tax still gets the full credit as a payment.
Child Tax Credit
The Child Tax Credit (CTC) is worth up to $2,200 per qualifying child under age 17 for the 2025 tax year. Up to $1,700 per child is refundable, so families who owe less than the full credit in tax can still receive the refundable portion as cash. The refundable piece begins once a household has at least $2,500 in earned income, then phases in at 15 cents per additional dollar earned above that threshold.
Premium Tax Credit
The Premium Tax Credit helps households afford health insurance bought through the Affordable Care Act marketplace. Eligibility is tied to household income relative to the federal poverty level, and the credit is generally paid directly to the insurer to lower monthly premiums.11Internal Revenue Service. Questions and Answers on the Premium Tax Credit If a household overestimates its income during the year, the credit can turn into a refund at tax time.
Help That Arrives as Goods and Services
Not all redistribution lands in a bank account. Several major programs deliver specific things (food, medical care, housing) that carry real financial value without moving cash to the recipient.
SNAP
The Supplemental Nutrition Assistance Program (SNAP) issues electronic benefit transfers that can be used to buy groceries such as fruit, vegetables, meat, dairy, and bread, but not alcohol, tobacco, vitamins, hot prepared foods, or non-food items.12Food and Nutrition Service, U.S. Department of Agriculture. What Can SNAP Buy Eligibility is generally based on household income relative to the federal poverty level. By covering grocery costs, SNAP frees up money the household can put toward rent, utilities, or transportation.
Medicaid
Medicaid pays healthcare costs for eligible low-income individuals. Instead of receiving money, participants have their medical bills paid directly by the government to doctors, hospitals, and other providers, covering routine care, emergencies, and long-term services.13Office of the Law Revision Counsel. 42 USC 1396 – Medicaid and CHIP Payment and Access Commission That coverage can be worth thousands of dollars a year and keeps medical bills from pushing lower-income families into debt.
Housing Choice Vouchers
The Housing Choice Voucher Program, often called Section 8, helps low-income families, elderly individuals, veterans, and people with disabilities afford housing in the private rental market. The government pays a housing assistance payment directly to the landlord, and the tenant pays the rest, typically around 30 percent of adjusted monthly income, though it can run as high as 40 percent.14U.S. Department of Housing and Urban Development (HUD). Housing Choice Voucher Tenants Housing is the biggest expense most households face, so the subsidy frees up a large share of income for everything else.
Shared Services Funded by the Tax Base
The government also redistributes indirectly by paying for services anyone can use, funded disproportionately by higher earners through the progressive tax system.
Public Education
Public K–12 education is one of the clearest examples. Funded largely through property taxes and state revenue, public schools give every child free instruction and facilities. Pooled tax dollars mean higher-wealth property owners help pay for the education of children from lower-income neighborhoods, and families who could not afford private school get the same basic access.
At the college level, the federal Pell Grant program applies the same idea by giving need-based grants to undergraduates from lower-income families. For the 2026–27 academic year, the maximum Pell Grant is $7,395.15Knowledge Center. 2026-27 Federal Pell Grant Maximum and Minimum Award Amounts Pell Grants do not have to be repaid, so they are a direct transfer of tax revenue toward educational opportunity.
Infrastructure and Public Spaces
Roads, bridges, and transit are funded through a mix of fuel taxes, general income tax revenue, and dedicated federal trust funds. The Highway Trust Fund draws most of its revenue from excise taxes on gasoline and diesel. These investments give mobility and economic access to everyone, including people who contribute little in tax, letting workers commute and businesses ship goods.
Public libraries and parks work the same way. They are supported by the collective tax base and deliver services that individuals would otherwise pay for through subscriptions, gym memberships, or internet fees, keeping a baseline of access that does not depend on personal wealth.
The Benefits Cliff
One real limit of all this is the benefits cliff: the sudden loss of assistance that can hit when a small raise pushes a household over an eligibility threshold. Many programs use hard income cutoffs rather than gradual phaseouts, so a modest bump in pay can sometimes leave a family with less total spending power than before. A single parent earning $15 an hour who gets a 50-cent raise could lose enough in SNAP, Medicaid, or childcare subsidies to come out behind.
The pressure is sharpest for workers earning roughly $13 to $17 per hour, where several program thresholds tend to cluster. SSI shows the same problem on the savings side: its $2,000 individual and $3,000 couple resource limits push recipients to avoid building up assets that could disqualify them.6Social Security Administration. 2026 Cost-of-Living Adjustment (COLA) Fact Sheet Some states have tried smoother phaseouts to soften the cliff, but it remains widespread across federal programs, and it is worth knowing about before turning down a raise or extra hours.
