$42 million Montana mansion owner loses property tax fight

March 24, 2015

As a homeowner who every year thinks that my local tax assessor has a much too inflated opinion of my house's worth, I certainly sympathize with anyone who fights for a lower real estate tax bill.

But even I think the owner of what one real estate company lists as largest private home in Montana was asking a little too much of tax officials.

Don Abbey of La Mirada, Calif., wanted his 2014 property tax bill of $367,696 on his lake mansion reduced by at least two-thirds.

Not going to happen.

The Montana Tax Appeal Board has upheld the $41.8 million value of the mansion built on an island in Flathead Lake. The ruling comes after a three-day hearing last November that reportedly involved at least a dozen attorneys and expert witnesses.

The 24,000-square-foot house, which also boasts a 5,000-square-foot boathouse, was built in 2011 by Don Abbey of La Mirada, California. The properties are located on Shelter Island, which sits along the western shore of Flathead Lake near Rollins, Montana, were listed for sale a few years ago at a $79 million asking price.

Sales price vs. tax price: Now we all know that when we get ready to sell our homes, we tend to inflate their value. You've got to build in some negotiating room.

So it's not surprising that Abbey dropped his estimation of his mansion a bit when tax time rolled around. But the value Abbey says should be assigned his home by the tax assessor seems a bit unrealistic. His attorneys argued that it's worth just $9.8 million for tax purposes.

Really? That's quite a brazen request, especially since the property is once again for sale, this time with a $44.8 million price tag. At the time it went back on the market — and when the tax protest was filed — it listed at $59 million.

Nothing ventured, nothing saved: Of course, we all know that rich people don't get and stay that way by being timid. Remember former Republican presidential candidate Mitt Romney's effort to dramatically cut his coastal California home's real estate taxes?

Don't get me wrong. Everyone has the right to protest what they see as an unfair tax bill. Just because some is rich doesn't mean they should pay a tax bill that's incorrectly calculated. 

But folks also need to do a reality check when they fight the tax collector. Asking for a reduction in a taxes based on an overly aggressive devaluation will not get you anywhere but to the bank to get the money to pay the higher tax bill.

TAX-SAVVY WAYS 
TO WRAP UP 2026

It’s over! With October’s extended filing deadline behind us, it is now time to focus on year-end moves to reduce your 2026 tax bill. 

You’ll find ways to do just that on the Tax Tips page (see the More Tax Posts drop-down menu at the top of the blog), as well as the separate tax tip pages for each month, notably October through December. If you’re on the Tax Tips page, you’ll find a monthly list at the end of this column. If you’re on another blog page, you can head straight to the October tips; at the bottom of that tips page you’ll find links to all the other 11 months’ collections of tax advice.

Not to spoil what you’ll find in that tax advice, but it does cover such things as tax deductions for charitable donations, investment moves that could reduce tax due, and ways to max out your tax-favored retirement savings. 

Finally, as the year winds down, things get hectic. There are lots of other things to occupy our time, like the much more fun upcoming holidays. But don’t lose sight of taxes, since timing is key. To be of use, most tax moves must be made by the end of the tax year. That’s Thursday, Dec. 31, which also is the last business day of the year. 

So that you don’t miss that final tax year deadline, also keep an eye on the countdown clock below. It will keep you on top of just how much time is left to make important, tax-saving moves. (Note: I’m in the Central Time Zone, so adjust accordingly for where you live.)
