Succession Planning and Tax Optimisation in Switzerland
Succession planning represents a fundamental aspect of asset management for any Swiss resident. In a country where the tax system varies considerably from one canton to another, anticipating and structuring the transfer of assets requires in-depth legal expertise. Switzerland offers a sophisticated legal framework allowing one to organise one's succession while minimising the tax impact, but the rules can prove complex. A tailor-made approach, taking into account the matrimonial regime, the family situation and the composition of the assets, constitutes the basis of an optimal transfer. The specificities of Swiss succession law, combined with cantonal tax particularities, create an environment where assistance from specialist lawyers becomes a major asset in effectively preserving and transferring one's assets.
Legal Instruments Available for Succession Planning
| Instrument | Nature | Advantages | Limitations |
|---|---|---|---|
| Will | Revocable unilateral act | Flexibility, modification possible | May be contested; reserved shares must be respected |
| Succession pact | Contract between parties | Legal certainty, unilaterally irrevocable | Less flexibility, unanimous agreement to modify |
| Lifetime gift | Anticipated transfer | Often more favourable tax regime, reduction of the taxable base | Clawback periods (3–10 years depending on canton) |
| Gift with reserved usufruct | Transfer of bare ownership | Reduced tax value; retention of income/use | Irrevocable except with donee's agreement |
| Life insurance (third pillar B) | Direct designation of beneficiaries | Immediate liquidity, favourable tax treatment | Reserved share to be verified |
| Family foundation | Patrimonial structure | Durability, collective management, possible tax advantages | Strict conditions, administrative costs |
| Trust (recognised foreign trust) | Flexible management structure | International flexibility, asset protection | Tax complexity, disclosure obligations |
Legal Foundations of Succession Planning in Switzerland
Swiss succession law rests primarily on the provisions of the Civil Code. One of the fundamental principles is that of reserved shares, which protects certain heirs. The 2023 succession law reform has modified these reserved shares:
- The children's reserved share is now 1/2 of their statutory share (compared to 3/4 previously)
- The spouse's reserved share remains at 1/2 of their statutory share
- The parents' reserved share has been abolished
- The freely disposable share has therefore increased
Tax Treatment of Gifts and Successions According to Degree of Kinship
| Beneficiary | General tax treatment (French-speaking cantons) |
|---|---|
| Surviving spouse | Exemption in most cantons |
| Direct descendants | Exemption or reduced rates (GE: 0%, VD: up to 7%) |
| Ascendants | Variable taxation, often with allowances |
| Collaterals (brothers, sisters, nephews) | Progressive taxation (GE: up to 22%, VD: up to 25%) |
| Persons without family connection | Highest rates (GE: up to 54.6%, VD: up to 50%) |
Optimisation Strategies for Family Transfers
Gifts with Reserved Usufruct
This technique consists of transferring the bare ownership of an asset while retaining its usufruct. It presents several advantages:
- The donor continues to receive the income from the asset or to have the use of it
- The tax value of the gift is reduced since it only concerns the bare ownership
- Upon the donor's death, the usufruct is extinguished without new taxation
Life Insurance as a Planning Tool
Life insurance contracts constitute preferred instruments in the arsenal of the succession planner in Switzerland, offering:
- Direct designation of beneficiaries, partially circumventing succession rules
- Advantageous tax treatment in many cantons
- Protection against creditors in certain configurations
- Immediate liquidity for the heirs, facilitating the settlement of succession-related costs
Solutions for International Estates
The international dimension adds a considerable layer of complexity to succession planning. Persons residing in Switzerland but owning assets in different jurisdictions must integrate:
- The possibility of choosing the application of their national law to govern their succession
- Potential conflicts between Swiss law and that of their country of origin
- Double taxation conventions in succession matters (concluded with Germany, France, the United States, the United Kingdom, etc.)
- Specific questions related to real estate located abroad

Frequently Asked Questions on Succession Planning
What is the difference between a will and a succession pact in Swiss law?
A will is a unilateral act revocable at any time by the testator. A succession pact is a contract between the future deceased and their heirs, binding on all parties: it may only be modified with the agreement of all signatories. The succession pact offers enhanced legal certainty and is particularly suited to transfers of family businesses.
How does the 2023 succession law reform impact my planning?
The reform that entered into force in January 2023 reduced the reserved shares: the parents' share is no longer protected, and the children's reserved share has been reduced from 3/4 to 1/2 of their statutory share. The freely disposable share (the portion one can freely dispose of) has therefore increased, offering more flexibility in organising the succession.
Can a life insurance policy be used to optimise succession planning?
Yes. Life insurance contracts allow beneficiaries to be designated directly, partially circumventing succession rules. The tax treatment varies according to the cantons but is often advantageous. Third pillar B life insurance offers great flexibility in designating beneficiaries and provides immediate liquidity to the heirs.
Can a foreigner residing in Switzerland choose the law applicable to their succession?
Yes. Under the European Succession Regulation (to which Switzerland is not a party but which influences practice) and Swiss private international law, a foreign national may choose the application of their national law to govern their succession. This choice must be formalised in the will or the succession pact.
