Moving from Washington to Paradise Valley: A Tax-Smart Relocation Guide

If you are a Washington resident weighing a move to Arizona, the short version is this: Washington's 2025 tax changes meaningfully raised the cost of building wealth there, while Arizona remains one of the lowest-tax states in the country. For people with significant investment gains or a sizable estate, that gap is now large enough to drive the decision — and Paradise Valley and Scottsdale are two of the most common places they land.

This is a general overview to help you frame the move, not tax or legal advice — confirm the specifics with your CPA or estate attorney (and note that Washington's estate rates are already scheduled to change again in mid-2026).

Washington vs. Arizona: the tax picture at a glance

What changed in Washington in 2025?

Two changes stand out for high-net-worth households:

• Capital gains tax went up. Washington's capital gains excise tax is 7% on long-term gains above the standard deduction (about $278,000 in 2025). A new 2.9% surtax now applies to gains over $1 million, for a top rate of 9.9% — effective for 2025 and reported on returns due in April 2026. (WA Dept. of Revenue)
• The estate tax got steeper. Washington raised its estate-tax exemption to $3 million but also raised the top rate — to as high as 35% for deaths between July 2025 and June 2026, before a scheduled rollback to 20%. (WA Dept. of Revenue) It remains one of the most aggressive estate taxes in the nation.

Washington still has no tax on wage income — but for founders selling a company, investors realizing gains, or families planning around an estate, the capital gains and estate taxes are what increasingly tip the math.

What Arizona offers instead

• A flat 2.5% income tax — the lowest flat rate of any state that has an income tax.
• A 25% subtraction on net long-term capital gains, which lowers the effective rate on those gains well below 2.5%. (AZ Dept. of Revenue)
• No state estate or inheritance tax at all.

For someone planning a major liquidity event or thinking about generational wealth transfer, establishing Arizona residency before that event can be consequential — which is exactly why so many of the buyers we work with are coming from Washington.

Paradise Valley or Scottsdale — which fits you?

Both sit in the same corridor (ZIP 85253 for Paradise Valley) and share the climate, golf, and dining, but they have different characters:

• Paradise Valley is the ultra-luxury enclave — large lots (typically an acre or more), guard-gated communities, mountain views, and a deep new-construction and custom-build market. Quieter and more residential.
• Scottsdale offers more variety and amenities — walkable districts, resorts, nightlife, and a wider range of price points and home styles.

Many relocating buyers choose Paradise Valley for a primary estate and use Scottsdale for everything around it.

A mini relocation checklist

1. Talk to a CPA about timing. When you establish Arizona residency relative to a sale or other liquidity event can matter a great deal — get this right before you move assets or sign anything.
2. Establish Arizona domicile. Spend the majority of the year here, get an Arizona driver's license, register to vote, and move your primary financial and personal ties to the state.
3. Plan the home search early. Paradise Valley's new-construction and custom-build inventory moves on its own timeline; if you want to build, start before you sell up north.
4. Line up local professionals. A Paradise Valley agent, a custom builder (if you're building), and an Arizona estate attorney will save you time and missteps.
5. Visit in summer. It's the honest test of desert living — and the best season to negotiate.
