HB 1224

Expanding eligibility to married filing separately (MFS) filers may reduce household-level benefit access: Because the credit is calculated per individual (not household), two low-income spouses filing separately may each receive a partial credit (e.g., $300–$600 each), but the household may fall below the income threshold for full benefit eligibility under joint filing rules — effectively penalizing couples who file separately due to financial instability, domestic circumstances, or strategic tax planning. This undermines the credit’s intent to support families and may reduce net household benefit relative to joint filing. The bill explicitly excludes application of the federal ‘separated spouse’ rule (Sec. 1(2)(a)(ii)(B)), increasing administrative complexity and reducing household-level benefit predictability.

The $50 minimum refund floor may disproportionately benefit higher-income within the eligible group: While intended to reduce administrative costs for small refunds, the floor effectively provides a $50 benefit to someone with income just below the phase-out threshold (e.g., $12,000 for no-children) who would otherwise receive $48 — a benefit that is negligible for middle-income households but relatively more meaningful for very low-income households. However, because the credit is funded by sales tax (a regressive revenue source), the *net fiscal effect* is that everyday people — especially low- and moderate-income shoppers — subsidize this benefit, and the $50 floor slightly dilutes the progressive intent by inflating refunds for near-eligible filers without increasing total household benefit proportionally.

Retroactive correction of underpaid refunds is subject to the existing nonclaim period (RCW 82.32.060(1)), which limits correction to 3 years — but only if the original refund was filed *within* that window. Since many low-income filers file late or miss deadlines, this provision may not meaningfully help those most in need. The bill allows amended applications “within the nonclaims period,” but that period is already narrow and administratively challenging for vulnerable populations. This creates a gap: the most at-risk applicants (e.g., those with irregular employment, housing instability) are least likely to meet the filing deadline, reducing the real-world impact of retroactivity.

The rebuttable presumption that Washington residents paid sales/use tax may lead to administrative denials and benefit gaps: While convenient for verification, the presumption assumes all residents paid sales tax — but some very low-income individuals (e.g., those relying on SNAP, Medicaid, or informal cash work) may pay little or no sales tax. If challenged, the burden shifts to the applicant to prove payment, which can be difficult without receipts or bank records. This creates a de facto barrier for the most vulnerable (e.g., unhoused, recently incarcerated, or severely disabled individuals), even if they meet EITC income rules. The bill does not relax the sales tax payment requirement for those with minimal consumption.

The 50% fraud penalty may deter legitimate applicants due to fear of punitive oversight: While fraud prevention is necessary, the harsh penalty (50% of overpaid amount) — especially when combined with interest and collection powers — may create a chilling effect. Low-income applicants who make honest errors (e.g., misreporting income, misunderstanding qualifying child rules) may face severe financial consequences, including wage garnishment or liens. This could discourage participation, especially among non-English speakers or those with limited tax literacy, undermining the outreach goals. The bill does not provide robust pre-claim guidance or error-correction support before penalties apply.
