The Step-Up in Basis: The Ultimate Tax Loophole for Generational Wealth

CORE INSIGHTS

  • The Reset Button: When you die, the IRS forgives all capital gains on your assets. Heirs receive them at “current market value.” This is the most powerful tax break in the code.
  • The Gifting Mistake: Gifting assets while alive transfers your low cost basis to the recipient. When they sell, they pay the tax you avoided. Inheriting is better.
  • Double Step-Up: In Community Property states, 100% of joint assets get a step-up when the first spouse dies. This is a massive advantage for surviving spouses.

“Buy, Borrow, Die.” This strategy relies on IRC Section 1014 (Step-Up in Basis). It transforms a lifetime of deferred taxes into tax-free wealth for the next generation. Holding until death is often the highest-ROI move.

IRC Section 1014: Basis Adjustment

The basis of property acquired from a decedent is the Fair Market Value (FMV) at the date of death.

*Translation: The IRS erases the original purchase price.

What-If Scenario: The $1.5M Family Home

Method Heir’s Basis Tax on Sale
Gift (Alive) $100,000 (Original) ~$460,000 Tax
Inherit (Death) $1,500,000 (Stepped-Up) $0 Tax
Result: Doing nothing (holding) saved the family nearly half a million dollars.

Strategic Action Steps

1
Audit “Low Basis” Assets
Identify stocks/property with huge gains. Flag these as “Do Not Sell.” These are prime candidates for Step-Up.
2
Avoid Joint Ownership
Don’t put kids on the deed while alive. It gifts them your low basis and forfeits 50% of the step-up. Use a Trust instead.
3
Community Property Trust
If in a common law state, consider a Community Property Trust (e.g., TN, SD) to secure the “Double Step-Up” for your spouse.

The Bottom Line: Who Should Choose What?

  • Keep it: Parents with highly appreciated assets. Let the step-up wipe out the tax liability.
  • Gift it: Only give cash or high-basis assets. Never gift appreciated property unless avoiding estate tax (#175).

Frequently Asked Questions

What is ‘Step-Up in Basis’?

When you inherit an asset, the IRS resets its cost basis to the market value on the date of death, wiping out capital gains taxes.

Should I gift my house to my kids now?

Generally, no. Gifting transfers your low basis to them. Inheriting it gives them a Step-Up, eliminating the tax bill upon sale.

What is the ‘Double Step-Up’?

In Community Property states, 100% of joint assets get a step-up when the first spouse dies, not just the deceased’s half.
