Everyone Wants Cost Seg. Almost Nobody Wants to Talk About Land Allocation.

Everyone Wants Cost Seg. Almost Nobody Wants to Talk About Land Allocation.

Lately I’m seeing a lot of investors get excited about cost segregation, bigger write-offs, and bonus depreciation.

That’s fine.

But here’s the question I think too many people skip:

Did you even get the land allocation right?

Because before you ever get to the sexy part of depreciation, you first have to separate the land from the building. And if that number is lazy, your depreciation is off from day one. The IRS is clear that land is not depreciable, and if the purchase includes both land and building, you have to allocate between them.

That matters a lot more than people think.

I see investors chase the big write-off and completely overlook the foundation underneath it.

Curious how others here are handling it.
Are most investors being too aggressive on land allocation, or are too many just guessing and hoping for the best?

    The tax assessor always has land right. At least right from minimizing a non depreciable asset perspective.

    I highly discourage RE investors and CPAs against using a 15% or 20% "rule of thumb" allocation for land, but at the end of the day, it's their call. Get this allocation wrong and the taxpayer could be facing an IRS audit or the possibility of missing out on a more favorable cost seg result. When providing preliminary analyses (estimates) for cost seg, we suggest using the appropriate County Tax Assessor/Appraiser's Office assessed land values or a separate land appraisal if more favorable to calculate the building's cost basis for purchased properties. The building's cost basis can be calculated by multiplying the land to total assessed value percentage by the purchase price, subtracting the result (land value) from the purchase price, and adding improvement costs if applicable.

    This is a good point. I used many cost seg report entry and tax benefit for my clients. I couldn't see any land deduction cost. Actually, I doubt the the thoroughness of the report on studying, seems mostly copy/paste.
