Land Sale Capital Gains Tax — LTCG + 1031 Exchange + Dealer Property (2026)

Quick summary

Selling raw land in the US triggers federal capital gains tax — but the rules are different from selling a house. No §121 exclusion (that's only for primary residences). No depreciation (land doesn't wear out). But two powerful planning tools: §1031 like-kind exchange defers ALL gain by rolling proceeds into another investment property, and capitalized property taxes can boost your cost basis if you elect §266.

The calculator handles three scenarios: investment land (LTCG rates if held >1 yr; STCG ordinary if ≤1 yr), business land used in trade/business (also capital gain treatment, plus possible §1231 gain), and inventory/dealer property (developer/flipper — taxed as ORDINARY income with self-employment tax on Schedule C).

Add 3.8% NIIT for high earners (raw land is investment property), state cap gains, and any AMT exposure. Use the result to decide whether to sell now, do a 1031 exchange, or hold for §1014 step-up at death.

How to use

1 Enter sale price and selling costs (real estate commission ~5-6%, title, transfer tax). These reduce amount realized.
2 Enter purchase price and capital improvements (clearing, grading, road/utility installation, percolation tests, well drilling). These build cost basis.
3 Enter accumulated property taxes paid — under §266, you can elect to CAPITALIZE these into basis instead of deducting Schedule A (especially valuable for non-itemizers).
4 Choose holding period (short ≤1 yr / long >1 yr) and use type: investment, business (§1231), or dealer/inventory (ordinary income + SE tax).
5 Enter filing status, other income, state rate. Click Calculate to see realized amount, basis, raw gain, federal tax, NIIT, state tax, total, and net proceeds.

Land Sale — Three Tax Treatments by Use

Use Type	Federal Tax	SE Tax?
Investment (held >1 yr)	0/15/20% LTCG + NIIT	No
Investment (held ≤1 yr)	Ordinary rates 10-37%	No
Business / §1231 (held >1 yr)	0/15/20% LTCG + NIIT (net §1231 gain)	No
Inventory (dealer / developer)	Ordinary rates 10-37%	YES — 15.3% SECA on Schedule C profit

Section 1031 Like-Kind Exchange

If you hold land for INVESTMENT or BUSINESS use (NOT inventory), you can defer ALL gain by rolling proceeds into another like-kind investment property under IRC §1031:

1031 Requirement	Detail
Like-kind property	Any US real estate (land, rental, commercial — all "like-kind" to each other)
Personal use excluded	Primary residences and second homes don't qualify
45-day identification	Identify replacement property within 45 days of sale
180-day acquisition	Close on replacement within 180 days of sale
Qualified Intermediary (QI)	Required — proceeds cannot touch your hands
Boot	Cash or non-like-kind property received is taxable
Debt relief	Mortgage paid off counts as boot unless replaced with equal/greater debt

Building Cost Basis for Land

Add to Basis	Note
Original purchase price	Cash paid + assumed mortgages
Buyer-side closing costs	Title insurance, recording, transfer tax, legal
Capital improvements	Clearing, grading, roads, utility install, percolation testing
Capitalized property taxes (§266)	Annual election if undeveloped/non-income land
Capitalized interest (§263A(f))	Construction-period interest
Soft costs during preparation	Engineering, surveying, environmental studies
Subdivision development	Land planning, zoning, plat costs

Dealer Property — When Land Becomes Inventory

If the IRS classifies you as a "dealer" — based on frequency of sales, intent, holding period, advertising activity, business setup — your land is INVENTORY, NOT a capital asset. Result: ALL gain is ordinary income + 15.3% SE tax. Combined effective rate often 40-50% vs. 15-25% for investment treatment.

Dealer Indicator	Mitigation
Multiple sales per year	Hold each parcel longer; avoid "subdivide & sell" patterns
Active marketing/advertising	Use a separate broker; minimize personal involvement
Subdivision improvements	§1237 5-parcel safe harbor for individuals
Pattern of subdivide-and-sell	Hold raw, sell whole

Step-Up in Basis at Death (§1014)

If you hold appreciated land until death, your heirs receive a STEPPED-UP BASIS to fair market value at date of death — eliminating ALL pre-death capital gain. For high-basis land that has appreciated significantly, this is often more tax-efficient than selling during your lifetime. Combine with the OBBBA $15M lifetime estate exclusion for tax-free generational transfer.

FAQ

Q How is land sale taxed in the US in 2026?

Investment land held >1 year: 0/15/20% LTCG + 3.8% NIIT for high earners. Held ≤1 year: ordinary rates 10-37%. Dealer/inventory land (developer/flipper): ordinary income + 15.3% SE tax on Schedule C. No §121 exclusion (that's only for primary residences).

Q Can I do a 1031 exchange on raw land?

YES — raw land held for INVESTMENT or BUSINESS use qualifies for IRC §1031 like-kind exchange. Defer ALL capital gain by rolling proceeds into another investment real estate within 45 days (identify) + 180 days (close). Personal-use land doesn't qualify. Use a Qualified Intermediary.

Q What is dealer property in real estate?

Property held PRIMARILY for sale to customers in the ordinary course of a trade or business. Frequent buying/selling, active marketing, subdivision development = likely dealer. Tax penalty: ordinary income + 15.3% SE tax instead of 0/15/20% LTCG. IRC §1237 provides a 5-parcel safe harbor for individuals.

Q Can I deduct land property taxes?

Yes — annual property taxes are deductible on Schedule A (subject to $10K SALT cap). Alternative: §266 lets you ELECT to capitalize property taxes into basis instead of deducting. Best for non-itemizers who can't use Schedule A anyway, or when AGI floor knocks out itemized.

Q Does NIIT apply to land sales?

YES — raw land is investment property, so the 3.8% Net Investment Income Tax applies if your MAGI exceeds $200K single / $250K MFJ. Frozen since 2013, no inflation adjustment. Adds significantly to total tax burden on big land sales.

Q How long must I hold land for long-term gains?

More than ONE YEAR. Hold ≤365 days = short-term ordinary rates. Day 366+ = long-term LTCG 0/15/20%. The clock starts the day AFTER acquisition. Critical to track with land that may have been split, gifted, or inherited.

Q What happens if I inherit land?

You get a STEPPED-UP BASIS to fair market value at the decedent's date of death (IRC §1014). When you sell, gain is calculated from FMV-at-death, NOT the decedent's original cost. This effectively eliminates ALL pre-death appreciation from tax. Major reason to hold appreciated land through life rather than gifting.

Q How do I improve land cost basis?

Capital improvements add to basis: clearing, grading, roads, utility installation, percolation testing, well drilling, plat/subdivision costs, environmental assessments. Also: capitalized property taxes (§266 election), capitalized construction interest (§263A(f)), professional fees during preparation. Keep all receipts — IRS audits land sales aggressively.
