2026 Penalty Tax on a Car Imported from Germany: What Actually Applies

The 2026 penalty tax scares people — and understandably so: with the threshold dropping, the cap climbing to €80,000, and headlines about a "retroactive penalty tax," many buyers are giving up on importing a premium vehicle from Germany for fear of the tax bill.

The problem is that most of the information circulating out there is wrong or outdated. Some sites are still quoting a reduction rule that was repealed back in March 2025. Others run headlines claiming "all used cars" will be hit by a retroactive penalty tax — which simply isn't accurate. The result: buyers either panic for nothing, or get caught off guard.

Here is what actually applies in 2026 to a used car imported from Germany, with no guesswork and no clickbait.

The 2026 penalty tax is really two separate taxes

When people talk about "the penalty tax," they usually lump together two separate charges that both apply at first French registration: the CO2 penalty tax and the weight tax.

The CO2 penalty tax (malus écologique)

This is the better-known one. In 2026, its scale got tougher:

• It now kicks in from 108 g of CO2/km (WLTP standard), down from 113 g in 2025
• It is progressive, gram by gram (not by bracket)
• It reaches its cap of €80,000 from 192 g/km

In other words, a large, recent petrol engine can theoretically hit the cap. That's what fuels the headlines about "the €80,000 penalty tax." But — and this is the whole point of this article — that cap only applies to a vehicle registered new. On an imported used car, the calculation is very different.

The weight tax (TMOM)

Less talked about, yet it hits premium SUVs hard. In 2026, its trigger threshold dropped from 1,600 to 1,500 kg. The scale is progressive, applied to the mass above the threshold:

Good news for certain buyers: fully electric vehicles are exempt, plug-in hybrids get a 200 kg allowance, and families with three or more children get a 200 kg reduction per dependent child.

The combined CO2 penalty tax and weight tax cannot exceed €80,000 — but again, that cap targets a vehicle registered new.

How the penalty tax applies to an imported USED car (the point everyone gets wrong)

This is where it really matters, and it's precisely what most articles fail to explain correctly.

It's the scale from the year of first registration that counts

For a vehicle already registered within the European Union (i.e., a used car from Germany), the penalty tax is not calculated on the 2026 scale. It is calculated on the scale from the vehicle's year of first registration.

A BMW first registered in Germany in 2020 is therefore subject to the 2020 penalty tax scale — where the thresholds were higher, the cap far lower, and the weight tax didn't yet exist in its current form. The difference compared with a "full 2026" calculation often runs into tens of thousands of euros.

The age-based reduction — and why "exempt at 10 years" is wrong

On top of the original year's scale, an age-based reduction is applied. The older the car, the more the penalty tax shrinks.

Important: the rule changed on March 1, 2025. The old system of "-10% per year, full exemption at 10 years," which is still quoted everywhere, no longer exists. It has been replaced by a reduction calculated in months, with:

• a more generous reduction for very recent vehicles,
• a slower reduction after that,
• full exemption reached at 181 months, i.e. 15 years and 1 month.

The exact month-by-month reduction table is set by official regulations and the public simulator: that is the authoritative source, not the approximate percentages copied across blogs. We deliberately avoid publishing a reduction scale "from memory" — on amounts like these, only the official figure, verified for your specific vehicle, matters.

Before 2015, the penalty tax is zero

A simple, reliable rule of thumb: any vehicle first registered before January 1, 2015 has a penalty tax of €0. The weight tax didn't exist yet, and the original CO2 penalty tax was far more lenient. For fans of premium youngtimers (E92 M3, B7 RS4, 997-generation 911...), this is a detail that changes everything.

The two misconceptions to drop in 2026

Misconception #1: "The retroactive penalty tax will hit every used car"

This is the big misunderstanding of the year. Many outlets have run headlines claiming 2026 would bring a "retroactive penalty tax" on used cars. The reality is quite different:

• The measure was pushed back to 2027 by an amendment passed in November 2025. In 2026, it is not in force.
• Even once it takes effect, it would not target "every used car," but a very narrow category: essentially former diplomatic vehicles and vehicles that benefited from a disability-related exemption at first registration. When resold to a regular buyer, the "dormant" penalty tax would become payable.

For the vast majority of buyers importing a premium used car from Germany, the "retroactive penalty tax" simply has no impact whatsoever.

Misconception #2: "-10% per year, exempt at 10 years"

As explained above, this rule was repealed as of March 1, 2025. If a seller or a website is still calculating a 10-year exemption for you, that's a clear sign the information is outdated — and a reason to double-check everything else they're telling you. Full exemption is now reached at 15 years and 1 month.

New vs. imported used: the real calculation logic

Rather than a single figure that's bound to be wrong, here is the logic to keep in mind. For the same premium model, the penalty tax depends dramatically on the date of first registration:

This is why the same vehicle can look like it carries an eye-watering penalty tax "on the 2026 scale" on paper, yet turn out to have a very reasonable penalty tax once actually imported as a used car. The devil — and the savings — are in the date.

How to legally reduce the penalty tax on an import

There's no miracle trick, but there are real, entirely legal levers:

1. Play the year of first registration. This is lever number one: a lighter original-year scale plus an age-based reduction. Targeting a used car that's a few years old rather than an almost-new one changes the equation.
2. Choose a version under the thresholds. A powertrain with CO2 under 108 g/km and mass under 1,500 kg escapes the 2026 penalty tax entirely.
3. Consider electric or plug-in hybrid if it suits your use case: exemption from the weight tax, and zero or minimal CO2 penalty tax.
4. Check for allowances tied to your situation (large families in particular).

That said, any scheme designed to artificially disguise the vehicle's true first registration date is fraud — to be avoided entirely. The only solid levers are the ones grounded in the vehicle's actual reality.

The real calculation is case by case

As you've now seen, the penalty tax on an imported used car depends on three variables — the exact CO2 and weight of the version, the year of first registration, and the corresponding reduction. No generic model spec sheet can give you that figure. Only the official simulator, run for a specific vehicle, is authoritative.

This is also, very concretely, one of the things we handle for you: before any purchase, we calculate the real penalty tax for the targeted vehicle, so the total cost — laid out earlier in our import cost guide — is known down to the euro, with no surprises when it's time to register the car.

In summary

• The 2026 penalty tax combines the CO2 penalty tax (from 108 g/km, capped at €80,000) and the weight tax (from 1,500 kg).
• On an imported used car, it's the scale from the year of first registration that applies, not the 2026 scale — followed by an age-based reduction.
• The "retroactive penalty tax" has been pushed back to 2027 and only targets a narrow category of cases: it does not apply to a standard imported used car in 2026.
• The old "exempt at 10 years" rule is outdated: full exemption is now at 15 years and 1 month, and any vehicle from before 2015 has zero penalty tax.
• The only reliable figure is calculated case by case, for a specific version and year.

Importing remains, in the vast majority of cases, a clearly winning move once the penalty tax is correctly calculated — but it has to be calculated correctly. If you want the real cost of your project, penalty tax included, let's talk directly: the analysis is free, with no obligation.
