Land-sale taxes

What taxes do you pay when you sell the land under your building?

Less than you fear, and far less than selling the whole property. The gain is computed on the land’s allocated basis only, there is no depreciation recapture because land was never depreciable, the ground rent you pay afterward is deductible, and if you want full deferral, the proceeds are 1031-eligible. You keep the building, the upside, and every dollar of its remaining depreciation.

Selling the land is the low-tax way to take chips off the table.

Depreciation recapture — the tax that stings when you sell a whole building — lives in the improvements, because only improvements were ever depreciated. Land was never depreciable, so the gain on a land-only sale is pure capital gain: no Section 1250 recapture, no ordinary-income surprise.
The math

Sell the whole asset vs. sell only the land.

A $10M property with $500K of NOI, bought years ago for $6M with a typical 20% land allocation ($1.2M land basis), and $1.5M of depreciation taken on the building. Two ways to raise cash:

What happens Sell the whole property ($10M) Sell only the land (~$3M via ground lease)
Gain recognized ~$5.5M — on everything, all at once ~$1.8M — on the land’s allocated basis only
Depreciation recapture Yes — $1.5M of unrecaptured §1250 gain taxed at up to 25% None. Land was never depreciated; recapture stays dormant in the building you still own
Character of gain Capital gain + recapture layer Long-term capital gain
The building and its upside Gone Still yours — operations, cash flow, promote, and all future appreciation
Ground rent going forward n/a A deductible operating expense
Want zero tax now? 1031 the whole sale — and buy a whole new property 1031 the land proceeds into any US real estate, same 45/180-day rules

Why this works: the IRS taxes what you sell. A ground lease sells the one layer of the deal with no depreciation history and the lowest basis-to-value drama, and leaves the tax-sheltered layer — the building — in your hands. Numbers above are illustrative; your allocation controls, so run it with your CPA.

Questions, answered

FAQ.

Do I pay depreciation recapture if I sell the land under my building?

No. Depreciation recapture applies to depreciated property, and land is never depreciable. Recapture exposure lives in the improvements — which you keep. The land-only gain is long-term capital gain.

How is the gain on a land sale calculated?

Sale price of the land minus the land’s allocated tax basis (from your original purchase-price allocation). Only the land layer’s gain is recognized; the building’s basis and its built-up recapture are untouched until you sell the building, if ever.

Is the ground rent I pay afterward deductible?

Yes. Ground rent on a true lease is an ordinary and necessary operating expense of the property, deductible like any other rent. That partially offsets the income the land sale freed up.

Can I defer the tax entirely?

Usually, yes — a leased-fee interest is real property, so the land-sale proceeds are 1031-eligible into any like-kind US real estate under the normal 45-day identification and 180-day closing rules. Talk to a qualified intermediary before closing; the exchange must be set up in advance.
