Most low and moderate-income households in the United States receive large lump sums of money each year when they file their federal income tax return. For many low to moderate-income households, the tax refund is one of the single largest payments received all year and may not be completely allocated to the household’s routine spending patterns because of its once-a-year timing. These factors make tax-time savings programs attractive interventions that could lead to substantial increases in the amount of savings and financial stability among low and moderate-income households.
