Real Estate Tahoe's short answer: almost always yes. The Section 121 primary-residence exclusion does not cover a second home, so the full gain is taxed federally at 0, 15 or 20 percent plus the 3.8 percent net investment income tax. On the California side, the state taxes the gain as ordinary income at rates up to 13.3 percent whether or not you live in California, and escrow withholds 3 1/3 percent of the sales price on Form 593. Nevada has no state income tax, but a California resident selling on the Nevada side still owes California on the gain, and Real Estate Tahoe sees that surprise at closing more than any other.
Real Estate Tahoe is a brokerage, not a tax adviser; this page is for planning the conversation with a CPA before you list. We put the closing statement, the improvement history and the Form 593 election in front of the seller's CPA before the home goes on the market.
Why the primary-residence exclusion does not apply
Under IRS Section 121 you may exclude the first $250,000 of gain from the sale of your home, or $500,000 for a married couple filing jointly, if you owned it and used it as your main home for at least 24 months of the previous five years. You can only have one main home at a time, and a Tahoe cabin you visit on weekends is not it.
Planning to move in first? The 2009 proration
Moving into the cabin for two years before selling works only partly. IRC 121(b)(5) denies the exclusion for gain allocated to periods after January 1, 2009 when the property was not your principal residence. The Pub 523 Worksheet 3 example: two rental years out of five owned means 40 percent of the gain stays taxable. On a cabin bought in 2012, every year before the move-in is non-qualified use, so most of the gain remains taxable. One exception helps: time after your last use as a main home does not count as non-qualified.
If you inherited the cabin, your basis is generally the fair market value at the date of death under IRS Pub 551; see selling an inherited Lake Tahoe home.
The federal bill: 2026 brackets and the 3.8 percent surtax
Owned more than a year, the gain is long-term capital gain. For tax year 2026, Rev. Proc. 2025-32 sets the brackets below. The gain stacks on top of your other income, so a large sale can push part of it into the 20 percent bracket.
| 2026 long-term rate | Single | Married filing jointly | Head of household |
|---|---|---|---|
| 0% | Up to $49,450 | Up to $98,900 | Up to $66,200 |
| 15% | $49,451 to $545,500 | $98,901 to $613,700 | $66,201 to $579,600 |
| 20% | Above $545,500 | Above $613,700 | Above $579,600 |
The net investment income tax adds 3.8 percent once modified adjusted gross income passes $200,000 for single and head-of-household filers, $250,000 married filing jointly, or $125,000 married filing separately. Real estate gain counts as net investment income under IRS Topic 559; gain excluded under Section 121 does not.
A worked example: a Tahoe City cabin bought in 2012
An illustration, not tax advice. A married couple filing jointly bought a cabin in Tahoe City, Placer County, for $650,000 in 2012, added $120,000 of documented improvements, and sell in 2026 for $1,500,000 with $90,000 of selling costs.
| Step | Amount |
|---|---|
| Purchase price (2012) | $650,000 |
| Documented improvements | $120,000 |
| Adjusted basis | $770,000 |
| Sale price | $1,500,000 |
| Selling costs | $90,000 |
| Amount realized | $1,410,000 |
| Taxable gain | $640,000 |
The federal rate on that $640,000 depends on the couple's other income. With $150,000 of other taxable income, the first $463,700 of gain fills the 15 percent bracket up to $613,700 and the remaining $176,300 is taxed at 20 percent: $69,555 plus $35,260, or $104,815. If other income already exceeds $613,700, the whole gain is taxed at 20 percent, $128,000; all at 15 percent would be $96,000.
The 3.8 percent net investment income tax applies too, since a $640,000 gain puts almost any couple above the $250,000 threshold; the ceiling is 3.8 percent of the full gain, $24,320. California taxes the entire $640,000 as ordinary income because Tahoe City is in California. At the top 13.3 percent rate that is $85,120; the actual rate is lower unless California taxable income passes $1,000,000. At closing, escrow withholds 3 1/3 percent of the $1,500,000 price on Form 593, $49,950, call it $50,000, as a deposit against the California bill.
Using the ceilings ($128,000 federal, $24,320 NIIT, $85,120 California), the combined bill tops out near $237,440 on a $640,000 gain; the real number will be lower, but that is the order of magnitude to plan around. Transfer tax is a separate line on the closing statement, covered on our Lake Tahoe transfer tax page.
California side vs Nevada side
The side of the state line decides the state tax. California side: South Lake Tahoe and El Dorado County, Placer County's North and West Shore including Tahoe City, and Truckee in Nevada County. Nevada side: Incline Village in Washoe County, and Stateline and Zephyr Cove in Douglas County.
| California side | Nevada side | |
|---|---|---|
| State rate on the gain | Ordinary income rates, top 13.3% over $1,000,000 taxable income | None. Nevada has no personal income tax |
| Withholding at escrow | 3 1/3% of sales price on Form 593, or the elective gain method | None |
| Seller lives in California | Owes California | Owes California, on all income regardless of source |
| Seller lives in Nevada | Owes California, as California-source income | Owes no state tax |
Three points trip up sellers. California has no lower capital gains rate; the top 13.3 percent is 12.3 percent plus the 1 percent Mental Health Services Tax over $1,000,000 under AB 1253, and the 14.4 percent figure seen online adds the 1.3 percent SDI tax, which applies to wages only. A nonresident owes California on a California-side sale because, per FTB Publication 1100, the gain is California-source income. And a California resident selling in Incline Village still owes California, because residents are taxed on all income regardless of source; Nevada's constitution bars any tax on personal income, so the Nevada side adds no state layer of its own.
If you rented the cabin
Under IRS Pub 544, gain is figured separately for the rental part and the personal-use part. Depreciation allowed or allowable on the rental part comes back as unrecaptured Section 1250 gain taxed at up to 25 percent under IRS Topic 409, and depreciation after May 6, 1997 can never be sheltered by Section 121, even if you later move in.
The 14-day rule
Under IRS Topic 415, rent the home fewer than 15 days in the year and the income is not reported and no rental deductions are taken. Above that, it is treated as used as a home if personal use exceeds the greater of 14 days or 10 percent of rental days; expenses are split by days and rental losses are limited to rental income. Permit holders should read our STR rules hub and selling a home with an STR permit; permits do not transfer to a buyer.
The 1031 exchange safe harbor
A Section 1031 exchange defers the gain, but both properties must be held for investment or productive use. For a dwelling unit, Rev. Proc. 2008-16 gives a safe harbor with three tests: owned at least 24 months before the exchange; rented at fair rental 14 days or more in each of those two 12-month periods; and personal use no more than the greater of 14 days or 10 percent of days rented. The replacement property must pass the same tests for 24 months after, so you cannot exchange and move in immediately.
What legitimately reduces the bill
- Basis and improvement records. In the example, $120,000 of receipts cut the gain by $120,000. Find the receipts before you list.
- Selling costs. Commissions, transfer tax, title and escrow fees reduce the amount realized.
- Timing the close across tax years. An early-January closing instead of late December moves the gain into a year where other income may be lower. See the best time to sell a Lake Tahoe home for market timing; your CPA covers tax timing.
- Installment sale. Under IRS Pub 537, carrying part of the price spreads the gain across the years payments are received; depreciation recapture is still reported in the year of sale.
- Charitable remainder trust. An irrevocable charitable remainder trust holds the property, the donor draws income for life or a term, and the deduction is limited to the present value of the remainder.
- Converting to a primary residence first, prorated for post-2008 non-qualified years as described above.
What happens at escrow: Form 593
On a California-side sale, escrow prepares Form 593 and you sign it at closing. The default withholding is 3 1/3 percent of the total sales price. The elective method instead withholds your California tax rate multiplied by your estimated gain, usually less on a home with a high basis, so bring the basis figures to escrow early. Withholding applies to residents and nonresidents alike under FTB Publication 1016. Two exemptions matter: a total sales price of $100,000 or less, or a property that was the seller's principal residence under Section 121, which a second home is not. Whatever is withheld is a prepayment credited on your California return; withholding does not relieve you of the obligation to file. The Nevada side has no state withholding, because there is no state income tax to prepay.

Frequently asked questions
Do I pay capital gains tax when selling my Tahoe second home?
Yes, in nearly every case. A second home does not qualify for the Section 121 exclusion, so the entire gain above your adjusted basis is taxed at the federal long-term rate of 0, 15 or 20 percent plus the 3.8 percent net investment income tax, and California adds ordinary income tax on a California-side sale wherever you live. Real Estate Tahoe recommends running the numbers with a CPA before listing.
How much is capital gains tax on a $1.5 million Tahoe sale?
It depends on your basis, not the price. A couple who paid $650,000, added $120,000 of improvements and paid $90,000 of selling costs has a $640,000 gain. Federal tax lands between $96,000 and $128,000 depending on other income, the net investment income tax adds up to $24,320, and California adds up to $85,120 at the top rate. Escrow withholds $49,950 toward the California bill.
Does California tax me if I live in Nevada and sell in Tahoe City?
Yes. The Franchise Tax Board treats gain on California real property as California-source income, so a Nevada resident selling in Tahoe City, Truckee or South Lake Tahoe owes California tax and has 3 1/3 percent of the price withheld at escrow. The reverse also holds: a California resident selling in Incline Village owes California because residents are taxed on all income.
Can I avoid capital gains by moving into my Tahoe cabin for two years?
Only partly. You qualify for the exclusion after 24 months as your main home, but IRC 121(b)(5) prorates out the gain attributable to years after 2008 when the home was not your principal residence. On a cabin owned since 2012, two years of residence shelters a small share. Real Estate Tahoe suggests having a CPA model the proration before you move.
