Tax on selling a car: do you have to pay tax on the proceeds?
Sold privately, so no tax to pay? Usually, yes. When the proceeds stay tax-free, how the car counts in your tax return and when trading is treated as a business.
In short
- Private sale: the proceeds are not income, and a gain is tax-free (Art. 16 para. 3 DBG).
- In your tax return, the car only counts toward your assets, valued by the canton’s rules.
- If you trade systematically for profit, you count as self-employed: income tax and AHV.
When you sell your car, the question comes up by your next tax return at the latest: do you have to pay tax on the proceeds? For private individuals, the answer is almost always no. Tax on selling a car only becomes an issue if you trade regularly, if the car belongs to a business or when it comes to wealth tax. This guide sorts out the different cases. It provides general information and is not tax advice; for your specific situation, your cantonal tax office or a fiduciary can advise you.
Private sale: the proceeds are not income
What you get for your private car is neither wages nor investment income, but the equivalent value of something you already owned. Any gain from it would be a private capital gain, and that is tax-free. For the direct federal tax, this is set out in Art. 16 para. 3 DBG; for cantonal and municipal taxes, in the Tax Harmonization Act, which exempts capital gains on movable private assets (Art. 7 para. 4 let. b StHG).
Usually the question doesn’t even arise, because a car loses value and you get less than you paid for it. You can’t deduct this loss: that’s the flip side of the tax exemption. A real profit is rare, for example with a classic car or a sought-after collector’s item. This gain, too, remains tax-free as long as you don’t trade commercially.
Tax on selling a car: overview by situation
| Situation | Tax consequence |
|---|---|
| private car sold below the purchase price | no tax, loss not deductible |
| private car sold at a profit | tax-free capital gain |
| regular buying and selling for profit | income tax and AHV contributions on the profit |
| car in business assets | gain above book value taxable, loss deductible |
| business car of a company liable for VAT | VAT on the sale price |
| car still owned on December 31 | counts toward your assets at its tax value |
| license plates handed in | motor vehicle tax refunded pro rata |
When selling turns into commercial trading
Only a gain from managing your own private assets is tax-free. If you systematically buy cars to resell them at a profit, you are self-employed, even if it is only a side business. The law does not set a fixed number of cars per year; the authorities look at the overall picture. The Tax Information dossier of the Federal Tax Administration (FTA) lists these characteristics:
- investment of work and capital
- a freely chosen organization, on your own account and at your own risk
- the intention to make a profit
- permanence and a systematic approach
- visible participation in the market, for example with ongoing listings
The consequences: the profit is income from self-employment (Art. 18 DBG), and social security contributions (AHV/IV/EO) are due on it (Art. 17 AHVV). From CHF 100’000 in annual turnover, you also become liable for VAT (Art. 10 MWSTG). In return, costs and losses are deductible. If you replace the family car with a new one, you’re nowhere near this. If you fix up and list several used cars every year, you’re better off clarifying your situation with the tax office and the compensation office (Ausgleichskasse).

Selling a business car: book value and VAT
If the car is part of the business assets of a self-employed person, the opposite of a private sale applies: capital gains are taxable (Art. 18 para. 2 DBG). The gain is the difference between the sale price and the book value. If the car has been heavily depreciated, a taxable gain can therefore arise even if you sell it far below its price when new. If the price is below the book value, the loss is deductible.
With mixed use, the predominant use decides: if more than half of the car’s use is for business, it belongs entirely to the business assets. If you transfer it to your private assets, this is treated like a sale at market value.
VAT on a business car
If your business is liable for VAT, selling a business car is a taxable supply: VAT at the standard rate of 8.1 percent must generally be accounted for on the sale price (Art. 18 and 25 MWSTG). This does not apply to vehicles that were used exclusively for supplies excluded from the tax. For an AG or GmbH, the book gain becomes part of the company’s profit.
Tip
With a business car, it pays to check your accounts before the sale: the book value determines whether you make a taxable gain or a deductible loss.
The car in your tax return: only under assets
Only the cantons and municipalities levy a wealth tax; the federal government does not. What counts is the situation at the end of the tax year (Art. 17 StHG): if you still own the car on December 31, it goes in the list of assets. If you sold it before then, the money in your account appears there instead. Household effects are tax-free, but a car doesn’t count as one of them. You don’t declare a leased car, because it doesn’t belong to you.
How Zurich, Bern and Aargau value cars
Each canton decides for itself how a private car is valued. Three examples from the guides to the 2025 tax return:
- In the canton of Zurich, you declare the current market value. As a rule, the value is reduced by 40 percent of the residual value per year.
- The canton of Bern calculates the tax value automatically from the year and price of purchase.
- The canton of Aargau works with percentages of the list price, graded by the year of first registration.
| Year | Bern: of the purchase price | Aargau: of the list price |
|---|---|---|
| in the first year | 65% | 70% |
| 1 year later | 42% | 50% |
| 2 years later | 27% | 35% |
| 3 years later | 18% | 25% |
| 4 years later | 12% | 15% |
| 5 years later | 8% | 10% |
| 6 years later | 5% | 5% |
| 7 or more years later | 0% | 0% |
In Bern, the first year is the year of purchase; in Aargau, it is the year of first registration. Neither scale applies to collector’s vehicles and classic cars; these are declared separately, in Aargau explicitly at market value.
How the sale changes your assets
The tax value is often below the market value. Example with round figures: A car you bought eight years ago has a tax value of zero in Bern. If you sell it for CHF 8’000, your declared assets increase by this amount, provided the money is still in your account on December 31. This only triggers a tax if your total assets are above the cantonal tax-free thresholds. In Zurich, for example, taxation for single people only starts at CHF 80’000 of taxable assets.
The guide to the free car valuation shows what your car is worth on the market.
Money back: motor vehicle tax and insurance premium
You get two amounts back after the sale, and neither has anything to do with your tax return. The motor vehicle tax is a matter for the cantons (Art. 105 SVG) and is paid in advance. When you hand in the license plates, the road traffic office (Strassenverkehrsamt) settles the account. In the canton of Bern, for example, motor vehicle taxes already paid are refunded pro rata. What counts is the day the plates arrive at the office, and any credit is first offset against unpaid invoices.
The process is described in the guide Deregistering your car after the sale. The overpaid insurance premium comes from your insurer; how to claim it is explained in the article Canceling your car insurance after the sale.
These taxes don’t apply to a private sale
- VAT: Only those who run a business are liable for VAT (Art. 10 MWSTG). As a private individual, you don’t charge VAT.
- Automobile tax: The federal government levies 4 percent on cars, but only on import and on manufacture in Switzerland (Art. 9 and 13 AStG). A sale within Switzerland does not trigger it.
For tax purposes, it makes no difference whether you list your car privately or sell it to a car buyer: for private individuals, the proceeds remain tax-free. The difference lies in the effort. verkaufedeinauto.ch makes you a firm offer based on your information and photos, pays at the handover by instant bank transfer and takes care of the deregistration at the road traffic office.

Frequently asked questions
Do I have to declare the sale of my car in my tax return?
Not as income. The proceeds from selling your private car are not taxable income, and you don’t enter them anywhere as earnings. The sale only shows up in your assets: the car drops off the list, and your account balance on December 31 is higher instead. Keep the sales contract. It lets you document the increase in your account if the tax office asks.
How many cars can I sell privately per year?
The law sets no fixed limit. What matters is whether you are managing your own assets or trading systematically with the intention of making a profit. If you replace your own car and perhaps the family’s second car, you stay in the private sphere. If you buy cars to resell them, invest work and capital in this and are active on the market, you are quickly considered self-employed. For side income of up to CHF 2’500 a year, AHV contributions are only levied on request (Art. 19 AHVV); the profit is still taxable.
Do I have to charge VAT when selling to a dealer?
No, not if you sell as a private individual. Only those who run a business are liable for VAT, and even then only from CHF 100’000 in annual turnover. For you, the agreed price is the final amount; you don’t issue an invoice with VAT. It’s different for a business car of a company liable for VAT: there, the sale is generally subject to VAT at the standard rate of 8.1 percent, and the amount belongs in the VAT return.
Is the profit from selling a classic car tax-free?
Yes, as long as the classic car is part of your private assets and you don’t trade commercially. The profit is then a tax-free private capital gain (Art. 16 para. 3 DBG). Keep the wealth tax in mind: collector’s vehicles are not covered by the cantons’ flat-rate tables but are declared separately, in Aargau, for example, at market value. If you regularly buy, restore and sell collector’s cars at a profit, you risk being classified as self-employed.
Can I deduct the loss in value of my car from my taxes?
Not for a private car. A loss on the sale of private assets is irrelevant for tax purposes, just as a gain would be tax-free. Depreciation is only possible on business assets. The deduction for commuting costs is a separate matter: it follows its own rules in the tax return and has nothing to do with the sale.
