TL;DR: The $100K charitable deduction cap is the visible problem. The less obvious risk is what happens when major donors change domicile: their advisers scrutinize continuing ties, and their relationships and giving may shift toward a new home. No blanket rule requires abandoning Washington charities. But nonprofits should take that risk seriously before ESSB 6346 takes effect on January 1, 2028.
The $100,000 cap on the charitable deduction is easy to see. It limits the new Washington income-tax benefit of giving, and it gives nonprofits a concrete policy issue to fight over.
But I worry that the larger damage could come as a second-order effect: wealthy Washingtonians moving to escape the tax, building lives elsewhere, and gradually redirecting gifts that once went to Washington institutions.
That second-order effect is the one I rarely see discussed — and it may do more lasting damage than the cap itself.
What the $100K cap actually does — and why geography matters.
The cap itself is straightforward. Under ESSB 6346 § 309, a taxpayer computing Washington taxable income may deduct charitable contributions claimed under section 170 of the Internal Revenue Code, but only up to $100,000 per individual — and spouses or domestic partners are limited to $100,000 combined, whether they file jointly or separately. Above that cap, additional gifts produce no further §309 deduction. Federal deductions and the separate capital-gains-tax charitable deduction require their own analysis.
But the amount is only half the story. The deduction is available only for gifts to a "qualified organization," and § 309 borrows that definition from RCW 82.87.080. A qualified organization must be both eligible to receive a charitable contribution under IRC § 170(c) and "principally directed or managed within the state of Washington" — meaning the place where its activities are "primarily directed, controlled, and coordinated." In other words, the deduction only rewards giving to Washington-run charities.
That geographic restriction gives a donor who remains subject to Washington income tax an incentive to support Washington-run charities, within the cap. It does not make claiming the deduction an admission of Washington domicile. Nor does it make the gift public: RCW 82.32.330 generally protects returns and tax information as confidential, subject to statutory exceptions. A publicly announced gift or continuing board role is a different kind of record.
Domicile is a facts-and-circumstances test.
When a high-net-worth Washingtonian moves to Nevada, Florida, Wyoming, or Tennessee to escape Washington's expanding tax base, they don't just sign a form. They have to prove a change of domicile — a question of intent demonstrated by conduct. The Department of Revenue, and any future income-tax enforcement regime, will look at the same factors states have used for decades:
- Where you spend your time
- Where you vote, drive, and register vehicles
- Where your physician, dentist, and accountant are
- Where your family lives
- Where your valued personal property sits
- Community ties: club memberships, houses of worship, professional associations, and charitable organizations
Community ties deserve careful review, but they are not all equivalent. A donation, an active board role requiring regular Seattle visits, and a membership retained after a move present different facts. None should be treated as an automatic veto of a genuine domicile change.
Charitable giving can be easier to redirect than family or business ties. That is the practical vulnerability for nonprofits: a donor need not be legally required to change beneficiaries for a move to change where the next major gift goes.
A development director should therefore ask two separate questions: what continuing involvement does the donor's actual residency plan allow, and what will keep the donor connected to the institution after the move?
Isn't there a Washington safe harbor for charitable giving?
The capital-gains regulation, WAC 458-20-301(6)(c), provides a nonexclusive list of domicile factors. It does not specifically list charitable giving or provide an express charitable-giving safe harbor. That leaves a question about how particular facts might be weighed; it does not establish that a gift defeats a move. The separate 30-day resident exception in RCW 82.87.020 is not a charitable-giving rule and does not itself change domicile.
New York shows why the distinction matters. New York Tax Law §605(c) expressly prohibits using qualifying charitable contributions to determine domicile. Washington could adopt a similarly explicit protection. That would reduce uncertainty for donors; it would not prevent a move from shifting their personal relationships and philanthropic priorities. Each state applies its own law when deciding a tax claim, so recognition of a new domicile by one state does not automatically bind another.
The advice donors may get.
A careful adviser should review the donor's continuing Washington ties and the law that actually applies. The advice should start here:
Make the move real. Document where you live and how your life has changed. Review continuing Washington involvement on its facts; do not assume that every charitable gift must stop.
My concern is that some donors and advisers will go further, reducing ties that feel unnecessary or uncertain. Others will keep supporting Washington causes but direct their next major commitment toward a school, hospital, or museum in their new community. Either way, the pipeline of major gifts can reorient. How much it will change is a question for evidence, not a foregone conclusion.
Why enforcement concerns matter.
A donor approaching a large liquidity event has reason to care about the strength of the domicile record. A disputed tax bill can be expensive to contest.
That concern can make donors cautious about continuing involvement in their former state. It does not mean a tax agency can disregard notice, assessment, collection, or appeal procedures, or that every unresolved domicile question leads to a bank levy.
Hugh Millen, the former NFL quarterback and now a KJR sports radio personality in Seattle, told this story on KJR's Softy & Dick show in March 2026. In his account, New York sought roughly $17,000 over a football game he had played there in 1992, and money was taken from his bank account before he could get the letter to his accountant. That is his account of a collection dispute, not a reported domicile decision or evidence that a charitable gift triggered enforcement.
The distinction matters: income earned from playing a game in a state is a sourcing question, separate from where a player is domiciled. The anecdote conveys the anxiety a collection dispute can create; it does not establish Washington's future audit practices or the treatment of a departing donor's gifts.
The bottom line.
When substantial tax is at stake, donors may want as little uncertainty as possible. Nonprofits should understand that pressure without telling supporters that a continued gift will invalidate their move.
Some donors will maintain their Washington commitments. Others may reduce them, whether because of advice, caution, new local relationships, or all three.
The cap is the obvious problem. The quieter risk is losing the relationship that produces the next gift, and the one after that. I think that risk deserves at least as much attention as the deduction limit. Its size is not yet established, but waiting for the loss to show up in a campaign report is a poor strategy.
A call to Washington nonprofits: join this fight before you feel it.
If you run a Washington nonprofit, or sit on the board of one, this is not someone else's fight. It is yours.
The constitutional challenge remains one route to stopping the law, and the repeal initiative is another; follow the Initiative 645 status tracker. Nonprofits have a stake in this debate. The donors who fund Washington's symphonies, museums, food banks, hospitals, universities, and social-service agencies can take their future giving with them. Boards should be asking what would keep those relationships strong if a donor leaves.
Concretely:
- Brief your board. Explain the distinction between domicile law and the risk that relocation changes giving.
- Speak publicly. Op-eds, joint coalition statements, and named voices from the nonprofit sector move the conversation. Quiet back-channel lobbying alone won't.
- Support the constitutional challenge. Consider an amicus brief explaining the nonprofit sector's stake. Concrete evidence about donor behavior would strengthen that contribution.
- Engage your major donors directly. Ask whether they are considering a move and how it would affect their support. Let them tell their stories.
- Model the financial impact. Stress-test the loss or reduction of several major gifts using your actual donor concentration. Label scenarios as assumptions, and distinguish them from forecasts.
The window to act is now — before the law takes effect, before exit planning calcifies into actual departures, and before the donor relationships you've spent decades building start to drift elsewhere.
