Beyond the Will: Estate Planning in Washington’s New Tax Era

TL;DR For many Washington families, estate planning has traditionally focused on creating a will or trust and ensuring assets pass smoothly to the next generation. But today’s tax environment calls for a broader conversation. Between Washington’s estate tax, capital gains tax, and the recently enacted Millionaires Tax scheduled to take effect in 2028, successful individuals, business owners, and investors have more planning considerations than ever before. While these laws affect different taxpayers in different ways, they share one important takeaway: proactive, coordinated planning can help preserve flexibility and reduce surprises. |
Estate planning is no longer just about what happens after you’re gone
Many people think of estate planning as drafting a will, signing a few legal documents, and checking a box.While those documents remain essential, they represent only one piece of a much larger financial strategy.
Today’s planning often involves coordinating:
- Estate and gift tax planning
- Income tax strategy
- Business succession
- Investment and retirement planning
- Charitable giving
- Family governance
- Wealth transfer across generations
When these pieces work together, families often gain more flexibility, improve tax efficiency, and create greater confidence that their wishes will be carried out.
Washington’s changing tax landscape raises new questions
Washington has become one of the more complex states for wealth and succession planning.Recent years have brought significant tax changes, including the state’s capital gains tax, updates to estate tax rules, and the passage of a new 9.9% tax on certain income exceeding $1 million beginning in 2028. While the new law is subject to ongoing legal challenges, it represents a meaningful shift in how high-income individuals may need to think about future planning.
These developments don’t necessarily mean dramatic changes are required. They do mean it’s worth asking whether your existing plan still aligns with today’s rules.
For families with closely held businesses, significant investment portfolios, or anticipated liquidity events, waiting until a transaction occurs can limit available planning opportunities.
Planning opportunities often begin years before a major event
One of the biggest misconceptions about estate planning is that it happens after a business is sold or retirement begins.In reality, some of the most valuable planning occurs well before those milestones.
Consider a business owner preparing for an eventual sale. Before negotiations even begin, they may have opportunities to:
- Review ownership structures
- Evaluate trust strategies
- Consider lifetime gifting
- Coordinate charitable giving
- Assess future liquidity needs
- Model potential tax outcomes under different scenarios
Once a letter of intent is signed, many of those options become more limited. The same principle applies to families with concentrated stock positions, appreciated real estate, or investment portfolios expected to generate substantial taxable income over time.
A coordinated team creates better outcomes
Estate planning isn’t solely a legal exercise. It works best when attorneys, CPAs, financial advisors, insurance professionals, and family members communicate around a shared strategy.
As author and estate planning expert James E. Hughes Jr. has long emphasized, successful wealth transfer isn’t simply about transferring financial assets. It’s about preparing families for the responsibilities that come with them. Aligning financial decisions with family goals often proves just as important as minimizing taxes.
That collaborative approach helps ensure that decisions made in one area don’t create unintended consequences in another.
For example:
- A gifting strategy may affect future income taxes.
- A business succession plan may influence estate liquidity.
- Charitable giving may support both philanthropic goals and tax planning.
- Retirement income decisions may interact with future state tax obligations.
Looking at each decision independently can leave opportunities on the table.
Questions worth asking now
Whether or not you expect to be directly affected by Washington’s Millionaires Tax, now is an excellent time to review your broader financial picture.

Often, the answers reveal opportunities to strengthen an existing plan rather than start over.
Planning is about creating options
Tax laws will continue to evolve. Federal exemptions change. State rules change. Family circumstances change. The best estate plans aren’t built around predicting every legislative outcome. They’re built around creating flexibility so families can adapt as circumstances evolve.
As Peter Drucker famously observed, “The best way to predict the future is to create it.” That principle applies just as well to estate planning as it does to business strategy.
For Washington families, business owners, and investors, today’s changing tax environment is a reminder that estate planning isn’t a one-time event. It’s an ongoing process that should evolve alongside your life, your business, and your goals. The introduction of Washington’s Millionaires Tax is simply one more reason to revisit the conversation. Whether you’re preparing for a business transition, updating an older estate plan, or thinking about the next generation, thoughtful planning today can create more choices tomorrow.
