The Working Families Tax Credit (WFTC) is an annual tax refund of up to $1,330 for Washington state households with low and moderate incomes. The amount individuals and families can receive varies by household size and income and increases annually with inflation.
Unlike the federal Earned Income Tax Credit (EITC), the WFTC is available to people who file their taxes using an Individual Tax Identification Number (ITIN), which includes undocumented immigrants.
In 2025, around 300,000 households received an average cash boost of $722 from the WFTC. Over 420,000 children benefitted from the program. Read more about how to claim your WFTC, and find free resources to do so, in this blog post.
State EITCs, like the WFTC, are a critical, proven tool to help families meet their basic needs and have long-lasting health, education, and employment benefits.
The Millionaires Tax significantly expands the Working Families Tax Credit
Washington’s Millionaires Tax funds significant expansions to the Working Families Tax Credit that will go into effect in 2029. The new expansions to the program will make the WFTC the most comprehensive and inclusive state EITC in the country. Currently, around 350,000 households in Washington are eligible for the program. Under the new expansion, 460,000 more households will benefit from the WFTC, meaning the tax credit will reach a total of 810,000 households, or over 1 in 5 households in Washington.
The impact of this expansion will be large: over 570,000 more children will be eligible for the credit. This means that the program could cover over half of all kids in Washington (60%), up from a quarter (25%).
The expansion removes an age restriction that affected working seniors and younger adult workers without kids at home, who can now qualify for the credit.
The expansion also raises the income eligibility to more closely match the cost of living, meaning more households with moderate incomes will qualify.
