What We Do
McKarcher Law specializes in estate planning and estate administration for Idaho and Washington clients. We prepare will-based or trust-based plans that include powers of attorney for property and health care, health directives, and other related documents. We advise trustees and personal representatives in administering estates, whether through a court-based probate or private trust administration.
- Identifying and minimizing the risk of disputes
- Planning for income and capital gains taxes
- Planning for estate taxes, if applicable
- Providing asset protection for beneficiaries
- Professional administration, if desired and appropriate in the situation
Some believe their situation is “simple,” or that they just need a “simple” will. But consider, for example:
- Some may not have any assets subject to federal or state estate (or “death”) tax. In our experience, however, many Washington residents do not realize that a combined marital estate of $2.2 million or more that is administered with “simple” planning will likely expose the surviving spouse to Washington estate tax and all the tax filings and administrative cost that come with it. This is because each spouse’s $2.2 million Washington “exemption” must be used at his or her death or it is lost forever.
- Nearly everyone has significant income and capital gains tax exposure of which they are unaware, including issues arising from tax-favored IRAs or other retirement accounts.
- Those who gift assets to children before death often create unfortunate tax outcomes for the recipients. In many cases, it is far better (and just as straightforward) to give the relevant asset at death.

Joshua D. McKarcher
Josh was born and raised in Clarkston, Washington. He attended Washington State University, worked for a consulting firm for several years, and then moved to Washington, DC to attend law school at The George Washington University. After several years as an associate lawyer with Covington & Burling LLP, in Washington, DC, he moved his family back to his hometown, where he practiced at Clements, Brown, & McNichols, in Lewiston, Idaho, before opening McKarcher Law PLLC in Clarkston.
In law school, Josh served as an intern for a federal district judge, was Managing Editor of The George Washington Law Review, and graduated Order of the Coif in the top 2% of his class. At Covington & Burling, he argued and unanimously won a precedent-setting case involving corporate bankruptcy before the U.S. Court of Appeals for the Fourth Circuit. (Link here.) At Clements, Brown & McNichols, he twice argued and won before the Idaho Supreme Court (links here and here); and he was hired by a national banking association to draft and file an amicus (or “friend of the court”) brief in a business bankruptcy appeal before the U.S. Court of Appeals for the Sixth Circuit, arguing a position that prevailed with the court. (Link here.)
Josh’s background informs his holistic approach to estate planning and administration: an opportunity to minimize risk, reduce strain on loved ones, and increase beneficiaries’ flexibility, particularly regarding income tax and asset protection.
