When a family property changes hands, well-meaning parents often think they are doing their adult children a favor by deeding a house over while they are still alive. It feels clean, avoids probate, and feels like an “inheritance ahead of time.”
However, from an IRS standpoint, there is a monumental difference between receiving a property as a lifetime gift and inheriting it after death.
Consider a common scenario faced by Pacific Northwest taxpayers: a married couple living in Washington who received a vacation cabin in New York from a living parent in 2024 and are preparing to sell it in 2026.
Here is how the numbers break down, the tax traps in play, and what the net proceeds look like when the dust settles.
The Scenario: A Tale of Two Bases
- Filing Status & Income: Married Filing Jointly (MFJ), living in Washington State with an ordinary household income of $170,000.
- The Property: A vacation cabin in New York (non-primary residence).
- Mother’s Purchase Price (1995): $60,000.
- Fair Market Value (FMV) at Transfer (2024): $210,000.
- Sale Price (2026): $125,000.
- Selling Costs: 6% Realtor Commission ($7,500). No outstanding mortgage.
1. The Core Misconception: “Gifted” vs. “Inherited” Basis
The most dangerous pitfall here is the assumption that this was an inheritance.
- Inherited Property (Step-Up in Basis): If the mother had passed away and left the cabin in a will or transfer-on-death deed, the couple would receive a “stepped-up basis” equal to the fair market value at her date of death (e.g., $210,000). Selling at $125,000 would have generated a substantial loss.
- Lifetime Gift (Carryover Basis): Because the mother is still living, the IRS treats this under IRC § 1015 (Gift Basis Rules). The recipients inherit the donor’s original carryover cost basis of $60,000, plus her original 1995 holding period (making this a long-term capital asset).
The $210,000 valuation in 2024 creates no tax benefit for federal capital gains purposes today.
2. The Net Proceeds & Tax Ramifications
Step A: Calculating Net Realized Proceeds
Gross Sales Price: $125,000
Less 6% Commission: -$7,500
Net Realized Proceeds: $117,500
Step B: Calculating the Taxable Capital Gain
Net Realized Proceeds: $117,500
Less Carryover Basis: -$60,000
Taxable Capital Gain: $57,500
(Note: Capital improvements made by the mother over the past 30 years—such as a new roof, septic, or structural upgrades—can be added to the $60,000 basis to reduce this gain. Good records are crucial.)
Step C: The Federal Tax Bite
For 2026, a married couple filing jointly with $170,000 in ordinary income falls into the standard 15% Long-Term Capital Gains bracket.
- Federal Capital Gains Tax: $57,500 * 15% = $8,625
- Net Investment Income Tax (NIIT): Because total Modified AGI ($170,000 + $57,500 = $227,500) exceeds the $250,000 threshold for joint filers, the 3.8% NIIT surtax does not apply.
Step D: The State Tax Complexities (Washington vs. New York)
- The Seattle / Washington Angle: Washington residents enjoy no personal state income tax. While Washington State levies a 7% capital gains tax on long-term profits exceeding statutory exemptions (adjusted annually around $250,000+), real estate sales are explicitly exempt under RCW 82.87.050, and this transaction falls well under thresholds regardless. Washington tax liability: $0.
- The New York Non-Resident Catch: Real estate is always taxed in the state where the physical dirt sits.
- Closing Prepayment (Form IT-2663): New York requires out-of-state sellers to submit Form IT-2663 (Nonresident Real Property Estimated Income Tax Payment Form) prior to closing. Rather than withholding against the gross sales price, New York requires estimated tax on the net gain ($57,500) at the state’s highest personal tax rate (currently 8.82%), meaning $5,071.50 must be remitted at the closing table.
- Filing the Nonresident Return (Form IT-203): When the couple files their New York nonresident return, the gain is taxed at their effective state rate (roughly 5.8% to 6.2% for their income bracket, or approximately $3,450). The $5,071 paid at closing serves as a credit, generating a refund of roughly $1,620 back into their pockets.
Estimated Bottom-Line Cash in Pocket
| Item | Amount |
| Gross Sale Price | $125,000 |
| Less: Realtor Commission (6%) | -$7,500 |
| Less: Estimated Federal Capital Gains Tax (15%) | -$8,625 |
| Less: Estimated New York Non-Resident Tax (~6%) | -$3,450 |
| Washington State Tax | $0 |
| Estimated Net Cash Retained | ~$105,425 |
(Note: At the closing table, total cash distributions will initially reflect the required New York Form IT-2663 estimated remittance of $5,072, with the remaining balance recovered upon filing).
Key Takeaways for Homeowners and Real Estate Investors
- Gifting Appreciated Real Estate Creates Unnecessary Liabilities: Had the parent utilized a revocable living trust or transferred the cabin via inheritance, the recipients would have secured a full step-up in basis, completely wiping out both federal and state tax liabilities on this transaction.
- Dig Up Historical Property Records: Documenting capital additions—replacing heating systems, drilling wells, or paving driveways—adds dollar-for-dollar value to the carryover basis and saves real cash.
- Entity & Portfolio Structuring: For our Northwest clients who operate active small businesses or manage real estate portfolios, cross-border assets require foresight. Holding investment properties within dedicated LLCs or executing Section 1031 like-kind exchanges can defer substantial capital gains liabilities into future wealth-building assets.
