TANF Indexation Methods Vary by State
A Niskanen Center report details how only ten states index Temporary Assistance for Needy Families benefits to inflation, with methods including linking to
Only ten states have mechanisms to automatically adjust Temporary Assistance for Needy Families (TANF) cash assistance for inflation, according to an analysis from the Niskanen Center. The remaining states leave benefits at fixed nominal amounts, which has resulted in a 46 percent loss in real value since 1996 in Georgia and North Carolina.
The report states that without indexation, the purchasing power of TANF benefits erodes as prices rise. This silent erosion means families receiving the same nominal check can afford less rent, food, and utilities over time. The federal TANF block grant itself has lost about half its real value since the program's creation in 1996 because it is not indexed to inflation or population growth.
Varieties of TANF Indexation
The ten states that do index benefits use one of four methods: linking to the federal poverty level (FPL), linking to a national inflation measure, using a state-specific cost-of-living index, or tying increases to state revenue growth. These methods produce significantly different benefit levels for a family of three.
| Indexation Method | States Using It | Example Benefit for Family of Three (2025) |
|---|---|---|
| Federal Poverty Level (FPL) | New Hampshire, Illinois, Texas, Connecticut | $1,332 (NH), $777 (IL), $382 (TX), $892 (CT) |
| Inflation (COLA) | Ohio, Maine | $623 (OH), $895 (ME) |
| State-Specific Cost Index | Wyoming | $902 |
| State Revenue Growth | California | $1,175 |
Indexing to the federal poverty level is the most common approach. The FPL is updated annually by the Department of Health and Human Services to reflect consumer price changes. States set their benefit as a fixed percentage of this level, automatically inheriting the annual adjustment. New Hampshire sets its benefit at 60% of FPL, Illinois at 35%, and Texas at 17%.
How Indexation Mechanisms Work
States that index to inflation, like Ohio and Maine, apply the Social Security Administration's cost-of-living adjustment (COLA) to their payment standard. The benefit difference between these states reflects the base amount each was paying when indexation began. Maine increased its maximum benefit by 20 percent in October 2024 before indexing, while Ohio began indexing in January 2009 without raising its base.
Nebraska uses an indirect method, adjusting its standard of need biennially to the Consumer Price Index from a 1997 baseline and setting the payment standard at 55 percent of that figure. This biennial adjustment can cause benefits to temporarily fall behind inflation.
State-specific mechanisms aim to match local conditions. Wyoming indexes to its own Wyoming Cost of Living Index, which showed a 4.2 percent inflation rate in 2025. California ties benefit increases to growth in a designated state revenue subaccount, a mechanism that stalled in 2025-26 when revenue growth was insufficient.
The Niskanen Center notes that the lesson from other programs like the Child Tax Credit is clear: where indexation is absent, erosion of real value is a near-certainty over time.
