Gift Appreciated Stock or Hold for the Step-Up? The 8-Year Break-Even on a $100,000 Gift From an $18M Estate in 2026
Picture a widowed parent with an $18 million estate. Her daughter is about to buy a first home and needs $100,000 for the down payment. The parent has two ways to fund it. She can use cash from a CD. Or she can gift $100,000 of stock she bought years ago for $20,000.
Both look like the same $100,000 gift. They are not, and the difference can run from +$39,576 to −$60,905 over 15 years, depending on things most people never check. This post runs those numbers using the 2026 federal rules and this month's economic data.
A note on sources. Only one of the articles behind this post is macro data: the Bureau of Labor Statistics' "Major Economic Indicators Latest Numbers." The others are NerdWallet consumer-finance pieces (credit card transfer partners, a cruise points story, homebuying assistance, a side-hustle quiz). Each turns out to carry a useful lesson for this decision, and I'll flag which is which.
What August's numbers do and don't change
The BLS page lists the latest readings:
| Indicator (BLS, August 2026) | Reading |
|---|---|
| Consumer Price Index | +0.4% |
| Unemployment rate | 4.1% |
| Payroll employment | +162,000 (preliminary) |
| Average hourly earnings | +$0.10 (preliminary) |
Here is how each connects to a gifting decision.
Rates and the GRAT hurdle. The IRS 7520 rate is set from Treasury yields (120% of the mid-term AFR). It sets the hurdle a GRAT must beat. A hot inflation print puts upward pressure on yields, so the hurdle can drift up. We covered that mechanic in how the IRS 7520 rate shifts GRAT vs. IDGT math. I'll use an example 4.8% rate below. Check the actual published rate for the month you fund.
Inflation and the exemption. The federal basic exclusion is $15 million per person in 2026, indexed for inflation afterward. Higher inflation raises the threshold your estate has to clear. That helps you only if your assets grow more slowly than the index.
Here is a sensitivity, not a forecast. Say your $18M estate grows 5% a year for 10 years, to about $29.3M:
- With the exemption indexed at 2.5% a year, it reaches about $19.2M. The taxable excess is about $10.1M, and the tax is about $4.05M at 40%.
- If inflation ran at the pace one 0.4% month would annualize to (about 4.9%), the exemption reaches about $24.2M. The tax falls to about $2.05M.
One month is not a trend. Still, the estate tax bill you're planning around moves by seven figures on an inflation assumption alone. That's why a static "you're under the exemption, relax" answer is risky.
Jobs data. A 4.1% unemployment rate and +162,000 payrolls (preliminary) don't touch estate tax directly. They matter through the Fed, yields, and the growth rate of the assets you're moving, which is where the break-even below comes from.
The 1:1 vs. 1:0.7 lesson
NerdWallet's "Citi Adds Japan Airlines as Its Newest Transfer Partner" notes that the transfer ratio is 1:1 or 1:0.7 depending on the card. Move 100,000 points and you get either 100,000 miles or 70,000. Same points, 30% different outcome, decided by which account they sit in.
Your $100,000 gift works the same way:
- Held until death, a low-basis asset gets a step-up in basis. The embedded gain disappears for income tax.
- Gifted during life, it keeps your $20,000 basis (carryover basis). Your daughter inherits the gain when she sells.
- Cash has no gain to lose, so it transfers at a clean 1:1.
NerdWallet's "How I Earned 1 Million Points With My Family Cruise Booking" makes a similar point. Booking through an airline-branded portal earned far more than booking direct, for the same cruise. Which asset you gift from is your portal choice.
The worked example: four ways to fund $100,000
These are the assumptions. Every figure is an example, not a quote:
- Single filer, $18M estate, so federal tax applies at 40% above $15M.
- The gift is $100,000. The annual exclusion is $19,000, so $81,000 uses lifetime exemption and needs a Form 709.
- The $100,000 grows 7% a year for 15 years (multiple 2.759, to $275,903).
- The estate stays above the exemption, so the 40% rate applies at the margin.
- Your daughter's capital gains rate is 15% in one case and 23.8% (20% plus the 3.8% net investment income tax) in the other.
- Second-order effects, like the donor's tax payment shrinking the estate, are ignored.
| Strategy | Estate tax | Gain tax | Total cost |
|---|---|---|---|
| A. Hold the stock until death | $110,361 | $0 (step-up) | $110,361 |
| B. Gift $100K cash you already hold | $32,400 | $0 | $32,400 |
| C. Sell stock, pay 23.8% on the $80,000 gain ($19,040), gift the cash | $32,400 | $19,040 | $51,440 |
| D. Gift the low-basis stock, daughter sells at 15% | $32,400 | $38,385 | $70,785 |
| D. Same, daughter sells at 23.8% | $32,400 | $60,905 | $93,305 |
Why is the estate tax in the gift rows only $32,400? The $81,000 that uses exemption is added back to your tax base at its gift-date value. That's 40% of $81,000. Everything else, including all 15 years of growth, leaves your estate. The $19,000 exclusion portion leaves it entirely.
The ranking:
- Gift cash from a high-basis source (B): saves $77,961 versus holding.
- Sell and gift (C): saves $58,921 after the gain tax.
- Gift the low-basis stock (D): saves $39,576 at a 15% rate, or $17,056 at 23.8%.
- Hold (A): costs the most in this scenario, but only because the estate is taxable.
That last condition decides everything. If your estate ends up under the indexed exemption, strategy A costs $0 in federal estate tax. Gifting the low-basis stock then costs you the step-up for nothing. In that case, option D is a $60,905 mistake at a 23.8% rate.
This is the kind of analysis Voritanel runs for you, so you don't have to build the spreadsheet yourself.
The break-even: how long until gifting low-basis stock wins?
Gifting beats holding when the estate tax saved exceeds the gain tax created. With a gain multiple G on the $100,000 gift:
0.40 × (100,000 × G − 81,000) = gain rate × (100,000 × G − 20,000)
Solving:
- At a 23.8% gain rate, G must exceed about 1.706, or 71% growth. At 7% a year, that takes about 7.9 years.
- At a 15% gain rate, G must exceed about 1.176. That takes about 2.4 years at 7%.
Sensitivity at the 23.8% rate:
| Scenario | Net advantage of gifting low-basis stock |
|---|---|
| 5 years at 7% | −$4,919 |
| 10 years at 7% | +$4,228 |
| 15 years at 7% | +$17,056 |
| 15 years at 5% | +$6,038 |
| 15 years at 3% | −$2,401 |
Two things stand out. The break-even is not a fixed number. It moves with growth, time, and your daughter's tax bracket, which is exactly where a rule of thumb like "always gift appreciated assets" or "never give up the step-up" breaks. And the wins here are modest next to the losses if the estate falls under the exemption. That asymmetry is why the gift now vs. die with zero step-up trade-off deserves its own calculation.
Should the family use "free money" instead?
NerdWallet's "Locked Out: Should You Take 'Free Money' to Buy a Home?" describes homebuying assistance programs. They can lower upfront costs, but the trade-offs need weighing first. That applies on the parent's side of the table too.
A program may come with conditions. Read the terms for things like income limits, occupancy rules, or repayment triggers. A family gift has none of those strings. What it costs is the $81,000 of your lifetime exemption, and a Form 709 filing.
If your estate is far below the exemption, using $81,000 of it costs you nothing. The clean gift is probably the simpler path. If your estate is well above it, that $81,000 is not free. For a longer worked comparison, see our $100,000 down payment gift vs. a GRAT on an $18M estate.
Also check state rules. Some states run their own estate or inheritance tax with much lower thresholds. Massachusetts, for one, starts at $2 million, and states generally have no portability. A gift that looks free federally can still change your state bill.
Where a GRAT fits, and where it doesn't
A direct gift consumes exemption. A grantor retained annuity trust (GRAT) can move growth out of your estate while using almost none. It has a different risk, though: the growth has to beat the hurdle.
Take $2,000,000 of the same low-basis stock in a two-year, zeroed-out GRAT at the example 4.8% rate. The annual annuity payment is about $1,072,660. The remainder passing to your daughter, by asset growth:
| Annual growth | Remainder to daughter | Estate tax avoided at 40% |
|---|---|---|
| 4% (below hurdle) | $0 (trust fails; setup cost wasted) | $0 |
| 8% | $101,667 | about $40,667 |
| 12% | $234,761 | about $93,904 |
If you die during the term, the assets come back into your estate. The remainder also keeps carryover basis, so the gain-tax lesson above applies to it too. A GRAT solves the exemption-use problem but adds a growth-rate bet, and the hurdle can rise with the month's rate. For a broader comparison, see GRAT vs. IDGT vs. direct gift on a $10M asset.
Which option wins for whom
| Your situation | Likely leans toward |
|---|---|
| Estate well above the indexed exemption, plenty of cash or high-basis assets | Gift cash or high-basis assets now |
| Estate above the exemption, only low-basis assets, long horizon (8+ years) | Gift low-basis stock, if the donee will sell at 23.8% or less |
| Estate near or below the exemption | Hold low-basis assets for the step-up; gift cash sparingly |
| Large concentrated position, expected growth above the hurdle | Model a GRAT against a direct gift |
| State with its own estate tax | Run the state numbers separately before deciding |
The five inputs that change the answer
NerdWallet's "Quiz: What's the Best Way to Make Money?" works because it asks questions before it answers. Estate planning should do the same. Here are the five inputs the worked example depends on:
- Your projected estate at death, not today's balance sheet. Growth and the indexed exemption both move it.
- Your basis in the specific asset you'd gift.
- Your recipient's likely tax bracket at sale, including the 3.8% surtax.
- Your horizon. As the table above shows, 5 years and 10 years can flip the sign.
- Your state. A $2 million state threshold changes the whole picture.
Change any one of them and the winner in the table above can change.
What to do this week
This is an example, and your numbers will differ based on your specific situation. The $18M estate, $20,000 basis, 7% growth, 15-year horizon and 23.8% donee rate are all stand-ins. You don't need to decide anything today. You do need to know which quadrant of the table you're in before you write the check, and a month of CPI and jobs data is a reasonable prompt to check.
If you want your own basis, growth, horizon and state plugged into this comparison, you can model it at Voritanel. It runs the gift, GRAT and step-up scenarios side by side, so the math can speak for itself.
