Investing for Your Grandchildren in Switzerland: A Guide for Swiss Grandparents
As a Swiss grandparent, you have wealth AND time — the rarest combination in the entire financial system. How to invest for your grandchildren, what advance inheritance during your lifetime really delivers, and where the tax and family pitfalls hide.
The Short Version in Three Lines
- As a grandparent, you have the rarest financial lever in the system: wealth AND time. A birth gift of CHF 10,000 invested at 7% becomes CHF 33,800 by your grandchild's 18th birthday — a tripling through time alone. Add annual birthday contributions and the effect multiplies further.
- Three legally clean paths are available: deposit into the parents' existing child account (simplest), separate account in the grandchild's name (with parental cooperation), or grandparent-owned portfolio with later transfer.
- The most powerful strategic lever is advance inheritance during your lifetime: wealth that moves to the grandchild's invested account now has 20–30 more compound years than classic inheritance after death. With CHF 50,000, that means over CHF 200,000 difference by the time your grandchild reaches adulthood.
Featured Snippet — The Answer
Advance inheritance beats classic inheritance. CHF 50,000 gifted now = CHF 207,000 more for your grandchild.
Swiss grandparents who want to invest for their grandchildren hold the most powerful lever in the wealth system: enormous time for compound growth. A CHF 50,000 lifetime gift at birth, invested at 7% in the grandchild's account, becomes CHF 271,000 by their 25th birthday — versus CHF 64,000 if the same sum waits on a Swiss savings account until classic inheritance. Advance inheritance during lifetime is the most financially valuable gesture you can make as a Swiss grandparent.
You have something the parents of your grandchild typically do not yet have: liquidity without immediate need. Ideally, you are retired or at the end of your career. Your home is paid off, the pension is running, your own living costs are calculable. Wealth you keep "for the family" can work — if you let it.
This is a distinctly Swiss reality. The Boomer generation sits on the largest wealth concentration in the country's history. At the same time, many Swiss grandparents have a restrained savings culture — wealth is held in bank accounts at 0.5–1% interest, "for later," "for emergencies," "for the grandchildren." Until it eventually flows as inheritance — arriving precisely at the time when heirs need the money least for compounding.
This article shows how to do it differently. Three clear paths for grandchild investments, the legal and tax landscape in Switzerland, and the most powerful lever of all: advance inheritance during your lifetime. For the strategic context, see the hub article on Swiss child accounts.
The Unique Grandparent Lever — Wealth AND Time
Parents typically have only one of the two levers available: time (young parents have it, but they lack the capital), or wealth (established parents at 45+ have it, but their child is often already too old for maximum compound effect). As a grandparent, at the birth of your grandchild you typically have both simultaneously: accumulated wealth, and a grandchild with 18+ years of investment horizon ahead.
This is mathematically dramatic. See what various grandparent gifts become:
| Birth gift | Value at 18 @ 7% | Value at 25 @ 7% | Value at 65 @ 7% |
|---|---|---|---|
| CHF 2,000 | CHF 6,760 | CHF 10,855 | CHF 162,546 |
| CHF 5,000 | CHF 16,900 | CHF 27,137 | CHF 406,364 |
| CHF 10,000 | CHF 33,799 | CHF 54,274 | CHF 812,729 |
| CHF 20,000 | CHF 67,599 | CHF 108,549 | CHF 1,625,457 |
| CHF 50,000 | CHF 168,997 | CHF 271,372 | CHF 4,063,643 |
Calculation: future value at 7% nominal return. Returns gross of inflation, taxes, fees. Real values after 2% inflation roughly 30% lower.
A birth gift of CHF 10,000 — a typical Swiss grandparent amount for the birth of a grandchild — becomes CHF 33,800 by adulthood. You don't have to do anything more. You've made the transfer once, and time + the market do the rest. By your grandchild's retirement (at 65), it grows to over CHF 800,000 — a pillar of support for someone who will themselves be a grandparent by then.
And that's just the one-time gesture. If you additionally contribute annually (birthday, Christmas, Confirmation), the effect compounds further. A typical scenario:
The combined grandparent strategy
You make a one-time gift of CHF 10,000 at birth, plus annual contributions of CHF 200 over 18 years (CHF 100 each for birthday and Christmas). At 7% return: birth-gift growth CHF 33,800, annual contributions grow to CHF 6,800. Total at 18: CHF 40,600. Nominal contributed: CHF 13,600. Compound lever: 3.0× what was paid in.
The Three Paths for Grandparent Investments
Practically, you as a grandparent have three legally clean options for grandchild investments. Each has its own logic depending on family relationships, desired control, and tax situation.
1
Deposit into the parents' existing child account
Simplest solution. The parents already have an account; you transfer directly into it.
If the parents of your grandchild have already set up a child account or equity savings plan, you as grandparent can transfer at any time — you only need the IBAN. Note: with most savings plan providers (like arvy), this account is legally in the parents' name. That is not an obstacle for deposits — it actually makes the process simpler.
ProsNo own account opening. Money lands immediately in the right, professionally managed pot. Tax-neutral for you.
ConsNo own grandparent signature — money blends with parental contributions. You have no control over the investment strategy or use.
2
Separate account in the grandchild's name (with parental cooperation)
Account in the grandchild's name — parents must co-sign as legal representatives.
You can together with the parents open an account in the name of the minor grandchild. With a pure bank solution (savings account), this is straightforward. With an equity portfolio directly in the child's name (so-called "locked child assets", e.g., at True Wealth or UBS key4), you as grandparent gain an own visibility. Important drawback: at the grandchild's 18th birthday, the parental representation rights end, and the now-adult disposes independently.
ProsOwn account identity as grandparent contribution. Wealth legally with the child, protected from parental creditors.
ConsRequires parental cooperation. Loss of control at the 18th birthday — child then disposes independently.
3
Grandparent-owned portfolio with later advance inheritance
You hold the wealth in your own name — and decide in stages when and how you hand over to the grandchild.
You open a portfolio in your own name, which you mentally manage for your grandchild, and hand it over in stages or as a lifetime gift. Key advantage of this variant: you retain strategic control for as long as possible, and can plan the transfer in stages — a portion at Confirmation, a portion at majority, a portion at the start of studies. Upon the grandparent's death, the remaining wealth flows via the normal inheritance.
ProsMaximum control over timing and form of transfer. Flexibility for life-circumstance changes. Clear grandparent signature.
ConsYou pay wealth and income tax during the holding phase. Theoretical risk in case of personal bankruptcy/estate issues.
Our Recommendation
For most Swiss grandparents, Option 1 (deposit into the parents' account) is the right choice for smaller amounts up to CHF 5,000–10,000: minimum effort, maximum compound effect. Option 3 (own portfolio) becomes interesting at larger amounts (CHF 20,000+) when you want to pursue a deliberate lifetime inheritance strategy (see below). Option 2 makes sense if you as grandparent want to have a clearly visible identity in wealth building.
Advance Inheritance — The Most Powerful Lever
Here comes what gets too little attention: wealth transfer during your lifetime is mathematically almost always the better path than classic inheritance — if the money is invested rather than waiting.
See the math. Assumption: you have CHF 50,000 that you want to eventually pass to your grandchild. Three scenarios, all to the grandchild's 25th birthday (a plausible life-expectancy window from the grandchild's birth):
| Scenario | What happens | Value for grandchild at 25 |
|---|---|---|
| A) Hold until death, savings account 1% | CHF 50,000 in Swiss savings account 25 years, then inheritance | CHF 64,122 |
| B) Hold until death, conservative 3% | CHF 50,000 in cautious mixed investment 25 years, then inheritance | CHF 104,689 |
| C) Advance inheritance at birth, invested 7% | CHF 50,000 as lifetime gift, with grandchild in equity savings plan | CHF 271,372 |
The Advance-Inheritance Lever
Lifetime gift beats classic inheritance by factor 3–4
+ CHF 207,250
Difference between classic savings-account holding (Scenario A) and lifetime gift with compounding (Scenario C) on CHF 50,000 over 25 years. Even against a conservative 3% mixed investment (Scenario B), advance inheritance still wins by CHF 167,000. The reason is not "riskier" investing — it is the combined effect of earlier investment timing AND a higher risk premium for the long grandchild horizon.
This is not trivial. Swiss grandparents who "preserve" wealth for grandchildren until their own death often turn a well-meaning gesture into a mathematically suboptimal strategy. The money does arrive — but to a 25-year-old who needs the money less than a newborn with 65 years of investment horizon ahead.
Advance inheritance during lifetime isn't suitable for everyone — you must be confident you don't need the wealth yourself (for living expenses, care, etc.). But if you don't need it, lifetime gifting to your grandchildren is by far the most financially valuable act you can make.
Gift Tax Grandparent → Grandchild
The tax treatment of grandparent gifts to grandchildren in Switzerland is almost always favourable, though cantonally not quite as tax-free as parent-child gifts. The most important points:
- Three cantons without gift tax (Schwyz, Lucerne, Obwalden) — there all gifts, including to grandchildren, are completely tax-free.
- Most other cantons treat grandparent → grandchild as "direct descendants" with similarly favourable rates as parent → child. In most cases: fully tax-free or very high allowances.
- Some cantons (e.g., Vaud, Neuchâtel) have a reduced but non-zero rate for grandparent → grandchild — typically in the low single-digit range.
- Concrete recommendation: for amounts over CHF 10,000, always clarify with the cantonal tax office or a tax advisor. Rates and allowances change occasionally, and the situation varies depending on residence of grandparents and grandchild.
Practical tip: for larger gifts (CHF 10,000+), always create a written gift agreement. Not because oral gifts wouldn't be valid — they are. But for bank transfer, tax filing, and above all for family clarity.
Forced Share Rights — Relevant with Multiple Heirs
A point many grandparents overlook with spontaneous gifts: Swiss inheritance law recognises forced share rights (Pflichtteil). When you give large amounts to individual grandchildren, other heirs (e.g., other grandchildren, or siblings of the gift recipient's parent) can theoretically feel disadvantaged upon your later death and claim forced-share supplementation.
In practice this is rarely relevant at amounts under CHF 20,000–50,000, but can lead to family conflicts at more substantial gifts or with multiple grandchildren. Three pragmatic rules:
- With multiple grandchildren, aim for equal treatment. This protects against future conflicts and is also emotionally clean. If you give one grandchild CHF 10,000 at birth, mentally plan the same amount for other grandchildren.
- Document substantial gifts. With gift agreement, dated transfer, and where appropriate an explicit clause whether the gift is "subject to balancing" or "freely disposable".
- For very large gifts (CHF 50,000+), inheritance-law consultation. A notary or inheritance-law specialist can clarify the implications for forced shares and possible balancing obligations.
The Parents as Bridge — Family Diplomacy
A practical aspect often underestimated: your gifts to grandchildren must be coordinated with the parents. Otherwise tensions arise that emotionally burden financially sensible gifts. Three common pitfalls and how to avoid them:
Pitfall 1: "Bypassing" the parents. When you as grandparent transfer large amounts directly to the grandchild's account without coordination, parents often feel bypassed — they lose control over an account in their family. Solution: for amounts over CHF 2,000, always discuss with the parents whether the gift makes most sense to the existing child account, a new account, or an advance-inheritance structure.
Pitfall 2: Compensating with over-gifts. Some grandparents overdose materially to compensate for emotional distance. This is usually counterproductive — substantial financial gifts have more impact when they are rare and meaningful, not when they are frequent and oversized.
Pitfall 3: Unequal treatment of multiple grandchildren. Emotionally explosive. If you give one grandchild CHF 10,000 at birth, that has psychological implications for other grandchildren and their parents. A deliberate equal-treatment strategy over years avoids most conflicts.
Anti-Plush-Toy Pitch
One of the most common grandparent arguments: "I'd rather buy something nice you can touch." Understandable emotionally — but financially an expensive tradition. A plush toy for CHF 80 is worth nothing at age 18. CHF 80 as a birth contribution to the savings plan is worth about CHF 270 at 18 (at 7%). Over 5–10 years of such birthday gifts, the difference adds up to four- to five-figure amounts — wealth your grandchild can effectively use later.
Frequently Asked Questions
How much should grandparents save for the grandchildren?
There is no "right" number — it depends on your available wealth. Typical Swiss grandparent amounts: CHF 2,000–10,000 at birth, plus CHF 100–500 annually at birthday/Christmas. Those who can contribute more (e.g., CHF 20,000–50,000 as a lifetime advance inheritance) achieve by far the greatest impact.
What exactly is advance inheritance?
Advance inheritance is the transfer of wealth during your lifetime rather than only at death as inheritance. For gifts to direct descendants (including grandchildren), it is tax-free or tax-favourable in most Swiss cantons. The biggest advantage is mathematical: the money can be invested earlier and has more compound time.
Do I have to pay gift tax when I give money to my grandchild?
In most Swiss cantons, grandparent → grandchild gifts are tax-free or at very low rates. Three cantons (Schwyz, Lucerne, Obwalden) levy no gift tax at all. Some cantons (Vaud, Neuchâtel) have reduced but non-zero rates for grandparents. For amounts over CHF 10,000, clarify cantonally.
Can I as a grandparent open an account for my grandchild myself?
Not without parental cooperation. Parents are legal representatives — an account in the name of a minor can only be opened with their consent and signature. But you can open a portfolio in your own name at any time and manage it for your grandchild, with later transfer as a gift.
What happens to my grandchild portfolio if I die before the transfer?
If the account is in your name (Option 3), it counts in your estate and is distributed according to will or statutory inheritance law. If you want to ensure your grandchild receives the amount, specify in your will — or transfer in good time as lifetime gift.
Can my gifts violate the forced-share rights of other heirs?
For very substantial gifts (CHF 50,000+ per grandchild), theoretically yes — other heirs can make balancing claims. For smaller amounts practically irrelevant. For larger amounts, inheritance-law consultation recommended.
Should I give all grandchildren the same amount?
For family-pragmatic reasons, yes. Unequal treatment of multiple grandchildren is a frequent source of family conflict in Swiss inheritance disputes. A consistent equal-treatment strategy over the years avoids most problems.
Is it worth depositing into arvy when my daughter is already saving there for her child?
Absolutely. You only need your daughter's IBAN — at arvy, the account is legally in her name as mother, but deposits from third parties (grandparents, godparents, etc.) are possible at any time. The money flows automatically into the next monthly contribution and is invested in the same quality stock portfolio.
arvy Child Account
Deposit straight into your grandchild's savings plan — from CHF 1.
When the parents of your grandchild have an arvy child savings plan, you can deposit directly at any time. Swiss quality stocks like Visa, Microsoft, Nestlé. FINMA-regulated. Co-invested by the team with over CHF 100,000 of their own money.
