A Boulder couple who bought a modest house decades ago, held company stock through a few good runs, and kept a small rental now looks at their net worth with genuine surprise. They aren't 'estate tax people,' they'd say. Whether that's true — and whether it stays true — is exactly what estate tax planning is for.
The landscape is friendlier than many families assume. Colorado imposes no state estate tax and no inheritance tax, and the 2025 federal tax law made the federal exemption permanent at a higher level beginning in 2026, ending years of scheduled-sunset anxiety. For most Colorado families, the federal estate tax will simply never apply.
But 'most' is not 'all,' and tax planning has quietly shifted rather than disappeared. Founders, ranch and real estate owners, and families with property in other states still face real exposure — and for everyone else, the focus has moved from avoiding estate tax to managing income tax basis. Whiteford's Colorado team, backed by the firm's national trusts and estates platform, helps you figure out which camp you're in.
The good news: what Colorado families don't have to worry about
Colorado repealed its estate tax mechanism years ago and has never imposed an inheritance tax on beneficiaries. What your children receive from a Colorado estate arrives without a state-level death tax. Combined with the permanently higher federal exemption that took effect with the 2026 changes, the great majority of Colorado estates will owe no transfer tax at either level.
That reality should shape planning honestly. Families sometimes arrive carrying complex tax structures — or fear-driven urgency — that no longer fit the law. Part of our job is telling you what you don't need. A plan built around a tax problem you don't have creates real costs: lost basis step-up, unnecessary trust administration, and rigidity your family will wrestle with later.
Who still needs genuine estate tax planning
Exposure hasn't vanished — it has concentrated. Business owners whose companies are compounding, families holding appreciated Front Range and mountain real estate, and households with large retirement accounts and life insurance can cross the federal threshold faster than they expect, because the exemption is a snapshot while assets grow every year. Planning done while you're comfortably under the line is cheaper and more flexible than planning done after you've crossed it.
Geography matters too. Colorado doesn't tax estates, but several states do — and owning a vacation home, inherited farmland, or business real estate in one of them can pull part of your estate into that state's system. For families with genuine exposure, the toolkit remains rich: lifetime gifting, irrevocable trusts, insurance trusts, charitable strategies, and entity planning. The attorney's task is matching the tool to the actual problem.
- Owners of appreciating businesses, ranches, and investment real estate
- Families with property in states that impose their own estate or inheritance taxes
- Households whose life insurance and retirement assets push totals near the federal exemption
- Married couples who need portability elections handled correctly at the first death
- Families whose older plans contain formula clauses written for a much smaller exemption
The quiet shift: basis planning is the new tax planning
For families safely under the federal exemption, the most valuable tax planning today is about income taxes. Assets included in your estate at death generally receive a step-up in basis, erasing capital gain that accrued during life. Old strategies that pushed assets out of the estate — sensible when exemptions were small — can now cost heirs a step-up worth far more than any transfer tax saved. Plans written a decade or more ago deserve a fresh read for exactly this reason.
This is where individualized advice matters most. Whether to hold an appreciated asset until death, gift it now, or sell and diversify depends on your basis, your health, and your family's income picture — not a rule of thumb. Our attorneys tailor these decisions case by case, often alongside your CPA.
