Quick answer
Giving appreciated assets during life passes your carryover basis to the recipient. when they sell, they owe capital gains tax on appreciation since your original purchase. Holding until death typically gives the heir a stepped-up basis to the date-of-death value, eliminating income tax on lifetime appreciation. This tool compares the mechanics side by side using your numbers. It does not produce a tax recommendation; estate tax, gift tax, and non-tax factors require professional analysis.
Lifetime Gift vs Hold Scenario
Two common strategies for transferring appreciated assets to the next generation are: (1) gifting the asset during your lifetime, and (2) holding the asset and letting it transfer at death via inheritance. Each approach has different income tax, gift tax, and estate tax implications. This tool compares the basis mechanics and the estimated capital gains tax outcome under both scenarios using your inputs. It does not account for estate tax, state tax, or non-tax factors. Consult a tax attorney or CPA for your specific situation.

Scenario comparison
These calculations illustrate income tax mechanics only. They do not account for estate tax, gift tax, liquidity costs, investment returns, or state income taxes. Actual tax treatment depends on the asset type, holding period, specific facts, and current law. This is not a tax recommendation. Consult a CPA or tax attorney.
How the two strategies differ
Lifetime gift: carryover basis
When you gift appreciated property during life, the recipient generally takes your original cost basis. When they sell the asset, they owe capital gains tax on the gain measured from your basis. The gift itself is generally not a taxable event for the donor (no capital gains recognized on the transfer). However, if the gift exceeds the annual exclusion, it may reduce your lifetime gift/estate tax exemption.
Hold until death: stepped-up basis
Property transferred at death generally receives a stepped-up basis equal to the fair market value at the date of death. This eliminates the income tax on all appreciation that occurred during the decedent's lifetime. The heir can sell the asset immediately after inheritance with no capital gains tax on lifetime appreciation. The trade-off: the asset remains in your estate and may be subject to estate tax if your estate exceeds the exemption.
When lifetime gifting is still preferred despite the carryover basis
Some situations favor lifetime gifting even for appreciated assets: removing future appreciation from your estate (relevant for very large estates over the exemption), gifting to a recipient who will hold the asset long-term or who is in a 0% capital gains bracket, gifting to charity (no capital gains regardless), or non-tax factors (recipient needs, control transfer goals). The comparison is not purely about the income tax on the embedded gain.
Frequently asked questions
What happens to capital gains when you gift stock?
When you give appreciated stock as a lifetime gift, the recipient takes your original cost basis (carryover basis). When they sell the stock, capital gains tax applies to the appreciation measured from your original purchase price, not the value at the time you gave it. The gift itself does not trigger capital gains for the donor in most cases. However, if the recipient sells the gifted stock for less than your basis, their loss is limited to the difference between the fair market value at the time of the gift and the sale price.
What is a stepped-up basis at death?
When an heir inherits appreciated property, the heir's cost basis is generally stepped up to the fair market value at the decedent's date of death. This eliminates the capital gains tax on appreciation that occurred during the decedent's lifetime. For example, if you bought stock for $10,000 and it is worth $100,000 when you die, the heir's basis is $100,000. If they sell immediately, there is no capital gains tax on the $90,000 of lifetime appreciation.
Is it better to give assets during life or at death for tax purposes?
For appreciated assets, holding until death and passing them through inheritance often produces a more favorable income tax outcome for the recipient because of the stepped-up basis. Gifting during life passes your cost basis to the recipient, who owes capital gains tax when they sell. However, the estate tax, gift tax, lifetime exemptions, state rules, and non-tax factors (control, timing, recipient needs) all affect the optimal approach.
