Five-second answer

Claim we investigated

I-645 could mean higher taxes for thousands of small businesses, force families to pay sales tax for basic household items like diapers, and raise taxes for 460,000 Washington families.

False. I-645 repeals only the income tax; the family credit, diaper exemption and small-business tax relief all stay in place. The initiative's own repeal list, the Attorney General's explanatory statement and the House's nonpartisan staff summary all show the 2026 tax relief survives repeal; the 460,000 are families newly eligible for a credit that starts in 2029.

One-minute summary

What the evidence establishes

  • Established. I-645's only repeal clause lists 66 sections of the 2026 law; none is in Parts IX to XI (sections 901 to 1107), where the tax relief is.
  • Established. The Attorney General's explanatory statement says the credits, exemptions and deductions that came with the tax "would not be repealed and would remain in place."
  • Established. The 460,000 are families newly eligible for the Working Families Tax Credit, an expansion that begins in 2029.
  • Established. The sales-tax exemption for diapers, over-the-counter drugs and hygiene products is part of the relief that stays.
  • Established. The small-business relief also stays: the larger small-business B&O tax credit and the higher B&O filing threshold are in sections I-645 does not repeal.
  • Context. The relief keeps costing money, about $963 million in fiscal 2031 (our total of the fiscal note's line items), and repeal removes the tax meant to pay for it.
  • Not shown. Nothing shows I-645 itself would raise a tax. Cutting the relief would take a separate law, which a Legislature could pass by majority vote with or without I-645.
Important context: Engrossed Substitute Senate Bill (ESSB) 6346, passed in 2026, did two separate things: it created a 9.9% tax on household income over $1 million starting in 2028, and in other sections it cut sales taxes and business and occupation (B&O) taxes and expanded the Working Families Tax Credit, mostly from 2029. I-645 would repeal the first part; this check is about whether it also undoes the second.

I-645 could mean higher taxes for thousands of small businesses, force families to pay sales tax for basic household items like diapers, and raise taxes for 460,000 Washington families – just so those making over a million dollars in a year get a tax break.

Reading of the initiative's repeal clause against the 2026 session law Washington Secretary of State, Washington State Legislature United States 2026 Section 2 of I-645 is its only repeal clause. It lists 66 sections of chapter 238, Laws of 2026: the tax itself and its administration (sections 101 to 814), the amendment to Initiative 2111 (the 2024 law banning income taxes) in section 1201, the referendum-blocking clause in section 1208, and sections 1, 1203, 1209 and 1210. The 2026 law puts the relief in Parts IX to XI: the Working Families Tax Credit expansion in section 901, sales-tax exemptions in sections 903 to 908, business and occupation (B&O) tax relief in sections 909 to 911, and the repeal of most of the 2025 sales tax on services in Part X. None of those sections is on the list. The Secretary of State's copy of the initiative is a scanned image, so it can't be searched; we read the list page by page. The initiative's title says it repeals chapter 238 as a whole (see Common questions). Matching section numbers to the relief is our reading of the session law.

Reading of the 2026 session law's null-and-void clause Washington State Legislature United States 2026 Section 1202 of the 2026 law says that if a court of final jurisdiction invalidates the tax (section 201), sections 1 through 1003 and 1201 through 1209 are null and void, which would take the relief with them. I-645 does not repeal section 1202; it repeals section 201 by statute. A repeal by voters is not a court ruling, so by our reading the clause does not take effect under I-645. The clause does mean the relief would fall if the courts struck the tax down. This is our reading of the session law. We found no court ruling or official analysis on how section 1202 applies to a repeal; the Attorney General's statement that the relief remains is consistent with it. Washington State Legislature

Common questions

“I-645 would raise taxes on thousands of small businesses.”

Short answer: No

The 2026 law raised the small-business B&O tax credit and the minimum threshold for filing B&O taxes. Those changes are in sections I-645 does not list, and the Attorney General says they remain. Small businesses would keep that relief; only a new law could take it away.

“The initiative's own title says it repeals chapter 238, which includes the relief.”

Short answer: Not the relief

The title does say 'repealing chapter 238, Laws of 2026', which is the whole 2026 law. But the operative repeal clause, Sec. 2, lists 66 specific sections, and none is a relief section. The Attorney General, whose office wrote the ballot title, and the House's nonpartisan staff both read the measure by its list. No court has ruled on the question.

“If I-645 passes, families will pay sales tax on diapers again.”

Short answer: No

The diaper exemption is one of the sales-tax exemptions the 2026 law created and the Attorney General says would remain in place. I-645 does not list the sections that contain it. Only a new law could bring the tax back.

“You can't keep the tax cuts for working families and small businesses while eliminating the tax that pays for them.”

Short answer: Legally, you can

The No campaign's rebuttal says so in the pamphlet. In law, the cuts stay unless a Legislature repeals them. The real point is about money: the relief costs about $963 million in fiscal 2031, and I-645 removes the tax meant to fund it, so future budgets would have to cover it from other revenue or cuts. That is budget pressure, not a tax increase by I-645.

“Once the income tax is gone, the Legislature will repeal the relief.”

Short answer: It could; it hasn't

A Legislature can repeal any tax break by a simple majority, with or without I-645. That would be a separate bill with its own recorded vote. It is a prediction about future budgets, which voters may reasonably weigh, but it is not something I-645 does.

“I-645 is fiscally irresponsible, slashing billions in funding for education and healthcare, increasing taxes on 460,000 hard-working families, and jeopardizing tax cuts for thousands of small businesses.”

Our rating: Misleading

The No argument's opening sentence makes three factual claims. 'Increasing taxes on 460,000 hard-working families' is false as a legal effect, and states without a hedge what the sentence rated above says I-645 'could' do: the credit expansion those families would gain stays in place. 'Slashing billions in funding for education and healthcare' describes revenue the state would not start collecting until 2029, which would go to the general fund that pays for those services among others; it is forgone future money, not a cut to a current budget. 'Jeopardizing tax cuts for thousands of small businesses' fairly describes budget pressure: the relief stays in law but loses the tax meant to fund it. Taken together, the sentence presents a future budget choice as an immediate tax increase and cut, which leaves a wrong impression.

“The relief is tied to the income tax, so it falls when the tax does.”

Short answer: Only if a court strikes it

The 2026 law has one such link: section 1202 voids the relief if a court of final jurisdiction invalidates the tax. I-645 repeals the tax by statute instead and leaves section 1202 in place, so by our reading the clause does not apply. No other section we found makes the relief depend on the tax.

“The credit payments depend on future budgets, so the 460,000 families could still lose them.”

Short answer: As they do now

The fiscal note lists the credit payments as Department of Revenue expenditures, so each budget has to fund them. That is true with or without I-645: section 202 sent the tax revenue to the general fund, not to a dedicated credit account. Repeal makes the payments harder to afford; it does not cancel them.

“Voting Yes repeals the new income tax before it begins, preserves the Working Families Tax Credit, paid family leave, and small-business tax relief.”

Our rating: True

Each part checks out. I-645 would take effect 30 days after the election, and the first payments of the tax are not due until 2029, so it repeals the tax before anyone pays it. The Working Families Tax Credit expansion and the small-business relief are in sections I-645 does not repeal, and the Attorney General says they remain. Paid family leave is a separate program that I-645 does not list for repeal. What the sentence leaves out is cost: the relief stays in law but loses the tax meant to pay for it, about $963 million in fiscal 2031.

“This was never about schools or diapers, that's a scare tactic.”

Our rating: Mixed

Half of this holds up. On diapers, the Yes rebuttal is right: the sales-tax exemption for diapers stays in place under I-645, as this article finds. On schools, it goes too far. The 2026 law said the tax revenue was to fund the relief and to make public investments in K-12 education, health care, human services and higher education, and the revenue goes to the general fund, which the Attorney General notes pays for K-12 schools. None of it is dedicated to schools and the first payments are not due until 2029, but repeal does remove future revenue those budgets were expected to draw on. Calling that a scare tactic dismisses a real budget trade-off.

Conclusion

The sources that describe what I-645 legally does agree. The initiative's only repeal clause lists 66 sections of the 2026 law, and none is in Parts IX to XI, where the tax relief is. The Attorney General's explanatory statement, printed in the voters' pamphlet, says the credits, exemptions and deductions would not be repealed and would remain in place, and the House's nonpartisan staff summary lists only income-tax provisions among those repealed. That answers all three parts of the claim. The 460,000 figure comes from the governor's own description of the law and counts families newly eligible for the Working Families Tax Credit from 2029; repeal does not take that credit away. The diaper exemption stays. So does the small-business relief: the larger small-business B&O tax credit and the higher threshold for filing B&O taxes are in sections I-645 does not list. We rate the claim False rather than Misleading because it attributes to I-645 an effect the measure does not have. The real risk behind it, that a future budget cuts the relief, exists with or without I-645 and would take a separate law. Confidence is high because the operative repeal clause is explicit and two independent official readings agree with it. The main textual tension is the initiative's title, which says it repeals chapter 238, Laws of 2026, the whole law. Its operative section is narrower, both the Attorney General and House staff read the measure by that section, and we found no court ruling on the question. The 2026 law itself contains the one way the relief could fall automatically: section 1202 voids it if a court strikes down the tax. I-645 leaves that clause in place but repeals the tax by statute, which is not a court ruling, so by our reading the clause would not apply under I-645. The No campaign's underlying concern is real. The relief and the credit expansion keep costing money, about $963 million in fiscal 2031 by our total of the fiscal note's line items, and I-645 removes the tax whose revenue section 202 said would fund them. Future Legislatures would have to pay for the relief from other revenue, cut other spending, or repeal some of it. Repealing a tax break takes a new law, which a Legislature can pass with or without I-645; we found no such bill. Voters who worry about that risk are weighing a budget prediction, which is a fair thing to weigh; they are not being asked to approve a tax increase.

I-645 blows a $13 billion hole in the budget - don’t believe lies that we can keep tax cuts for working families and small businesses but eliminate the tax on the wealthy few that pays for them.

How we checked

  1. Defined the claim as the No campaign's own words in its voters' pamphlet argument: that I-645 could raise taxes for 460,000 families, reimpose sales tax on diapers and raise taxes on small businesses.
  2. Read the initiative's full text and listed every section its repeal clause names.
  3. Matched those sections against the 2026 session law to find where the relief is (Parts IX to XI), and read the law's null-and-void clause (section 1202).
  4. Read the Attorney General's explanatory statement and the House Office of Program Research summary of I-645.
  5. Traced the 460,000 figure to the governor's signing release and the Budget and Policy Center.
  6. Read the Department of Revenue fiscal note and the Washington Research Council's table of its line items for what the relief costs, and recorded limits: the scanned initiative text, the title's wider wording, and that we found no court ruling.

Editorial note: Scope: this article checks whether I-645 itself would raise taxes on 460,000 families or reimpose sales tax on diapers, as the No campaign's voters' pamphlet argument says. It does not rate whether repeal is good policy or how anyone should vote. The budget-pressure figures are FactHub's own totals of official estimates. The Secretary of State's copy of the initiative is a scanned image, so we read its section list page by page.
