What Is the Swiss Participation Exemption?
Three Qualifying Thresholds
A participation qualifies if the holding company meets at least one of three thresholds:
| Threshold | Condition | Minimum holding period |
|---|---|---|
| Capital threshold | At least 10% of the share capital of the subsidiary | Dividends: none. Capital gains: 12 months before sale. |
| Profit/reserve threshold | At least 10% of the profit and reserves of the subsidiary | Dividends: none. Capital gains: 12 months before sale. |
| Market value threshold | Market value of the participation at least CHF 1,000,000 | Dividends: none. Capital gains: 12 months before sale. |
Only one threshold needs to be met. The CHF 1 million market value threshold is particularly important for minority participations below 10% in high-value subsidiaries - a 5% stake in a CHF 25 million company qualifies even though it is below the 10% capital threshold.
How the Abatement Is Calculated
The Beteiligungsabzug calculation follows a four-step process:
Sum all dividends and capital gains from qualifying participations received during the tax year.
Subtract a deemed 5% management cost from gross qualifying income. Also subtract related financing costs: interest paid on debt used to fund the participation, and any depreciation of the participation's book value attributable to a distribution (e.g., a dividend that reduced net asset value). The result is net participation income.
Participation yield ratio = Net participation income / Total net taxable income of the company. This ratio expresses what proportion of the company's income comes from qualifying participations.
CIT actually payable = Total CIT at statutory rate x (1 - participation yield ratio). If net participation income equals 90% of total income, the effective CIT is reduced by 90% - near-zero for a near-pure holding company.
Worked Example
| Item | Amount (CHF) |
|---|---|
| Qualifying dividends received from subsidiary | 2,000,000 |
| Less: 5% management cost (2,000,000 x 5%) | (100,000) |
| Less: interest on acquisition debt | (50,000) |
| Net participation income | 1,850,000 |
| Other income (management fees, interest from third parties) | 150,000 |
| Total net taxable income | 2,000,000 |
| Participation yield ratio | 1,850,000 / 2,000,000 = 92.5% |
| Statutory CIT (Zug, 11.9%) | 238,000 |
| CIT abatement (92.5%) | (220,150) |
| CIT actually payable | 17,850 |
| Effective rate on total income | 0.89% |
Capital Gains: The 12-Month Holding Requirement
Capital gains on disposal of a qualifying participation are eligible for the abatement only if the holding company has held the participation for at least 12 months before the sale date. This is a hard deadline - a participation held for 11 months and 29 days does not qualify. The 12-month period is counted from the date of acquisition (legal transfer) to the date of disposal (legal transfer to buyer).
There is no equivalent holding period requirement for dividend income - a qualifying dividend received the day after acquisition qualifies.
The 5% Deemed Management Cost
The 5% deemed management cost is an anti-avoidance provision. Without it, a holding company could deduct all its actual management expenses against qualifying participation income, maximising the apparent net participation income while deducting costs at ordinary rates. The 5% cap on participation-related management costs is applied uniformly regardless of actual costs incurred.
Actual management costs of the holding company (salaries, office rent, director fees, audit, legal) are still deductible in the general CIT calculation - they reduce total taxable income. The 5% applies only within the participation exemption formula to determine net participation income for the ratio calculation.
The Indirekte Teilliquidation (Indirect Partial Liquidation) Trap
The indirekte Teilliquidation rule applies when all of the following conditions are met:
- A majority participation (over 50% of votes) in a Swiss company is transferred to a buyer
- Within 5 years after the sale, the target company distributes earnings that existed as retained earnings at the date of transfer
- The seller was aware or should have been aware at the time of sale that the buyer intended to fund the acquisition with the target's retained earnings
If these conditions are met, the seller's capital gain is recharacterised as dividend income to the extent of the post-sale distribution. This matters because: (a) dividend income distributed from a Swiss company is subject to 35% withholding tax (VStG Art. 4); (b) recharacterisation as dividend income means the capital gain loses its capital-gain treatment, which is relevant where the seller is an individual (capital gains on movable private assets are generally tax-free in Switzerland for individuals, though not for companies).
For a Swiss holding company selling a subsidiary, this is primarily a concern about the buyer's intentions regarding the target's retained earnings. Structuring around indirekte Teilliquidation requires careful pre-deal analysis.
Foreign Subsidiaries and Treaty WHT Credits
The participation exemption applies to qualifying dividends from both Swiss and foreign subsidiaries. A Swiss holding company receiving dividends from a qualifying German subsidiary benefits from the Beteiligungsabzug. The German withholding tax on the dividend (5% under the Swiss-Germany DTT for a 25%+ holding) is credited against Swiss CIT under the Swiss credit system. Because the participation exemption reduces Swiss CIT to near-zero on qualifying income, the foreign WHT credit may be limited to the reduced CIT actually payable - the foreign WHT is not refundable beyond Swiss CIT.
This is particularly relevant for income from high-WHT source countries where the treaty rate is not zero. Planning requires comparison of the gross Swiss CIT (before exemption) against the foreign WHT to ensure the credit is not wasted.
TRAF 2020: What Did Not Change
A common misconception is that the TRAF reform changed the participation exemption. It did not. TRAF abolished:
- The cantonal holding privilege (Holdingprivileg) - a separate, status-based regime
- The cantonal domicile company regime
- The cantonal mixed company regime
- Principal company structures
The Beteiligungsabzug under DBG Art. 69-70 is a transaction-based relief (it applies to qualifying income regardless of the company's activity or status) and therefore was always OECD-compatible. TRAF left it entirely intact.
Frequently Asked Questions
What is the Swiss participation exemption (Beteiligungsabzug)?
A proportional CIT abatement under DBG Art. 69-70 that reduces tax on qualifying holding income (dividends and capital gains from 10%+ or CHF 1M participations) proportionally to their share of total income. Near-zero effective rate for pure holding companies.
What are the qualifying thresholds for the Swiss participation exemption?
Three alternative thresholds: at least 10% of share capital, or at least 10% of profit and reserves, or market value of at least CHF 1,000,000. Only one needs to be met. Dividends: no holding period. Capital gains: 12-month minimum.
How is the participation exemption calculated in Switzerland?
Net participation income (gross qualifying income less 5% management cost and financing charges) divided by total net taxable income gives the abatement ratio. CIT payable = total CIT x (1 - abatement ratio).
What is the 5% deemed management cost deduction?
5% of gross qualifying participation income is deducted as a deemed management cost when calculating net participation income for the abatement formula. Actual management costs are still deductible elsewhere in the CIT calculation.
Does the TRAF 2020 reform affect the Swiss participation exemption?
No. TRAF abolished status-based cantonal regimes (holding privilege, etc.) but left the Beteiligungsabzug under DBG Art. 69-70 entirely unchanged. The qualifying conditions and mechanics are the same as before 2020.
What is the indirekte Teilliquidation trap?
DBG Art. 20a recharacterises a seller's capital gain as dividend income when the buyer funds a Swiss company acquisition with the target's own pre-existing retained earnings within 5 years. This eliminates the capital gain's participation exemption benefit for the seller.
Does the participation exemption apply to foreign subsidiaries?
Yes. Qualifying participations in foreign subsidiaries benefit from the Beteiligungsabzug. Foreign withholding taxes are credited against Swiss CIT under relevant double tax treaties, subject to the reduced CIT ceiling.
Can a Swiss shelf company use the participation exemption?
Yes, immediately upon acquiring qualifying participations. There is no seasoning period for the shelf company itself. The qualifying thresholds are assessed at the participation level.
