Capital Gains Tax on Land in Washington: What Sellers Should Know Before Selling
Selling vacant land, inherited land, or an investment parcel can create federal tax questions even though Washington's state capital gains tax does not apply to real-estate sales. Understanding gain, adjusted basis, holding period, inherited-property rules, and Washington REET can help you ask better questions before closing.
Capital gain on the sale of land: the basic federal framework
For federal tax purposes, the starting point is not simply the sale price. The IRS generally determines gain or loss by comparing the amount realized from the sale with the property's adjusted basis.
If the amount realized is greater than adjusted basis, there is generally a gain. If adjusted basis is greater than the amount realized, there is generally a loss. Whether a gain is capital, ordinary, currently recognized, deferred, or subject to another rule depends on the facts.
This is why two owners who sell similar Washington parcels for the same price can have very different tax results.
Four numbers and dates worth gathering early
- How and when you acquired the land.
- Your original cost or other starting basis.
- Records of qualifying improvements and other basis adjustments.
- The expected sale price and transaction costs associated with the sale.
The exact tax calculation should be reviewed with a CPA, enrolled agent, tax attorney, or other qualified advisor who can evaluate your facts.
Sale price, net proceeds, and taxable gain are not the same number
Sale price
This is the price or consideration in the transaction. It is the number sellers usually focus on first, but it does not by itself tell you what you keep or what your taxable gain may be.
Net proceeds
This is the practical cash-outcome question: what remains after applicable closing costs, liens, debt payoffs, taxes collected at closing, and other transaction items.
Taxable gain
This is a tax calculation. Federal rules focus on amount realized and adjusted basis, with additional rules potentially affecting recognition and character of the gain.
What does adjusted basis mean when selling land?
Land you purchased
The basis of property you buy generally starts with its cost. Federal basis rules can also include certain acquisition costs and later adjustments. Certain capital improvements can increase basis, while other events can reduce it.
For landowners, useful records may include the closing statement from the purchase, survey or legal costs that qualified for basis treatment, documentation of permanent improvements, and records connected with later changes to the property.
Land acquired another way
If you inherited the property, received it as a gift, or acquired it through another type of transfer, your starting basis may not be what the prior owner originally paid. Different federal rules apply depending on how ownership changed.
Do not guess at basis when the parcel has been in a family for decades. Reconstructing the acquisition history can materially change the gain calculation.
Short-term versus long-term capital gain on a land sale
For federal tax purposes, holding period matters. The IRS generally treats a capital asset held for one year or less as short term and one held for more than one year as long term.
That distinction can affect federal tax treatment. It is therefore useful to confirm the date you acquired title and the expected disposition date before assuming how a gain will be classified.
Special rules can apply, including for inherited property and certain other transfers, so the simple one-year rule should not be applied blindly to every transaction.
Why we are not publishing a one-size-fits-all tax rate
Federal capital-gains rates can depend on taxable income, filing status, the character of the property, and other facts. Publishing a single percentage would give many Washington landowners the wrong answer.
A better planning approach is to determine the likely gain, identify the holding period and property use, and have a qualified tax professional apply the current rules to your return.
Inherited land can have a very different basis
Inherited land deserves special attention because federal basis rules generally do not simply carry forward what the deceased owner originally paid. IRS guidance states that the basis of inherited property is generally tied to fair market value at the date of death, although alternate valuation, estate-tax reporting, conservation-easement rules, and other exceptions can affect the result.
Federal holding-period rules also generally treat inherited property as held for more than one year, regardless of how long the beneficiary personally held it.
For heirs, this makes the date-of-death value and estate records particularly important. If the property was inherited recently, gathering the appraisal, probate documents, estate-tax information when applicable, and other valuation records can make the eventual tax review much easier.
Does Washington State capital gains tax apply when you sell land?
Washington's capital gains tax does not apply to the sale or exchange of real estate. The Washington Department of Revenue expressly states that this is true regardless of how long the seller owned the property, whether the seller occupied it, where the property is located, whether it is commercial or residential, or whether it is owned by an individual, trust, or business.
That does not mean a Washington land sale is automatically free of tax. Federal income-tax rules can still apply to the gain, and Washington has a separate real estate excise tax system for transfers of real property.
This federal-versus-state distinction is important: a seller can have a federal capital-gains issue even though the sale of the land itself is excluded from Washington's capital gains tax.
Washington REET is different from capital gains tax
Real Estate Excise Tax
Washington's Real Estate Excise Tax, commonly called REET, is a separate tax regime associated with transfers of real property. It should not be confused with either federal capital-gains tax or Washington's capital gains tax.
REET has its own rules, rates, affidavits, exemptions, and local components. Whether an exemption applies depends on the facts and the applicable Washington rules.
Why this matters to your net proceeds
A seller estimating net proceeds should consider more than federal capital gain. Depending on the transaction, closing costs, liens or debt payoffs, REET, and other charges can affect what is actually received at closing.
That is why a tax calculation and a closing-proceeds estimate should be treated as related but different exercises.
Vacant land and the home-sale exclusion are not the same conversation
Many property owners have heard about federal tax rules for selling a principal residence. A vacant investment parcel should not automatically be treated as though it were a qualifying principal residence.
The tax treatment can depend on how the property was used, whether it was connected with a residence, and other facts. If you are selling land separately from a home, or selling acreage with mixed personal and investment use, get advice specific to that transaction rather than relying on a general home-sale rule.
What if the land was held for business or investment?
Property held for investment or used in a trade or business can raise additional federal tax issues. The result may depend on the property's use, improvements, depreciation history, development activity, and whether the owner is viewed as holding property for investment or primarily for sale.
That distinction can also matter when considering a potential Section 1031 exchange.
Can investment land qualify for a Section 1031 exchange?
Potentially. IRS guidance provides that Section 1031 can apply to qualifying exchanges of real property held for business or investment for other qualifying like-kind real property. When the requirements are met, recognition of gain can generally be deferred rather than simply eliminated.
However, real property held primarily for sale does not qualify for Section 1031 treatment. The exchange rules also involve strict transaction structure, timing, replacement-property, and documentation requirements.
If a 1031 exchange might be relevant, investigate it before closing or taking control of sale proceeds. This is an area where early coordination with a qualified tax professional and exchange intermediary is important.
A practical pre-sale tax checklist for Washington landowners
Confirm how you acquired the land
Purchase, inheritance, gift, family transfer, entity distribution, and other acquisition methods can lead to different basis questions.
Reconstruct your basis records
Gather closing statements, estate or probate records, appraisals, and documentation of improvements or other relevant adjustments.
Estimate the transaction
Separate expected sale price, transaction costs, estimated net proceeds, and the tax gain calculation instead of treating them as one number.
Identify special issues early
Inherited property, installment terms, investment use, business use, development activity, and a possible 1031 exchange can all warrant additional review.
Review federal and Washington items separately
Federal gain rules and Washington REET are different systems. Washington's capital gains tax excludes real-estate sales, but that does not resolve the federal calculation.
Get transaction-specific advice
Before closing, have a qualified professional confirm the tax treatment, reporting requirements, and any strategy that depends on timing.
Need to understand the land itself before deciding whether to sell?
Tax planning is only one part of the decision. Goan Properties Limited can review the Washington parcel, including basic property characteristics and potential issues that may affect marketability. You can then compare your selling options and discuss the tax consequences with your own qualified advisor.
Bottom line
When land is sold for more than its adjusted basis, the transaction can create a federal gain. The amount and tax treatment depend on how the property was acquired, its adjusted basis, holding period, use, and other facts. Inherited land can follow different basis and holding-period rules from purchased land.
For Washington sellers, there is also an important distinction: Washington's capital gains tax does not apply to sales or exchanges of real estate, but Washington REET is a separate real-estate transfer tax and federal tax rules can still apply.

Frequently asked questions about capital gains tax and land sales
How is capital gain generally calculated when selling land?
At a high level, federal tax rules compare the amount realized from the sale with the property's adjusted basis. If the amount realized is greater than adjusted basis, there is generally a gain. The actual taxable result can involve additional rules, so sellers should confirm their calculation with a qualified tax professional.
Is selling vacant land subject to federal capital gains tax?
A sale of vacant land can create a federal taxable gain when the amount realized exceeds the property's adjusted basis. The character and treatment of that gain depend on facts such as how the property was held and how long it was owned.
What is adjusted basis in land?
Basis generally starts with the property's cost when purchased, or another basis rule when property was acquired by inheritance, gift, or another method. Certain qualifying costs and improvements can increase basis, while other items can reduce it. Good records are important.
What is the difference between short-term and long-term capital gain?
For federal tax purposes, a capital asset held for one year or less generally produces a short-term gain or loss, while one held for more than one year generally produces a long-term gain or loss. Special rules can apply in particular situations.
How is inherited land treated for capital-gains purposes?
Inherited property follows special federal basis rules. In many cases, the initial basis is tied to the property's fair market value at the date of death, although exceptions and estate-tax valuation rules can apply. Inherited property is also generally treated as held for more than one year for federal holding-period purposes.
Does Washington's capital gains tax apply when I sell real estate?
According to the Washington Department of Revenue, Washington's capital gains tax does not apply to the sale or exchange of real estate. That is separate from federal income-tax treatment and separate from Washington real estate excise tax.
Is Washington REET the same as capital gains tax?
No. Washington real estate excise tax, commonly called REET, is a separate tax connected with transfers of real property. A seller should not assume that exemption from Washington's capital gains tax means no Washington transaction tax can apply.
Can investment land qualify for a Section 1031 exchange?
Potentially. Federal Section 1031 rules can apply to qualifying exchanges of real property held for business or investment, but property held primarily for sale does not qualify. The timing and documentation rules are specialized, so professional guidance should be obtained before a sale is structured.
