# Your Marginal Tax Rate and all you need to know about it

|**Updated:**|

(Disclosure: Some of the links below may be affiliate links)

Your marginal tax rate is an important metric. But it is also a complex and misunderstood concept. Many beliefs about marginal tax rates are wrong.

So, in this article, I want to clarify the subject as much as possible. By the end, you will know how to estimate your marginal tax rate and its meaning.

## Marginal Tax Rate

We should start at the beginning: what is a marginal tax rate?

Your marginal tax rate is the rate at which new income is taxed. It is important to note that it is not your actual tax rate. Your actual tax rate is the rate at which your current income is taxed.

For instance, if you earn 100’000 CHF per year and pay 20’000 CHF in taxes, your actual tax rate is 20%. But if you earn an extra 1000 CHF annually, your tax bill may reach 20’300 CHF. It means you earn 1000 CHF more annually and pay 300 CHF in taxes yearly. So, your marginal tax rate is 30% (300 CHF / 1000 CHF).

The marginal tax rate is always at least as high as the actual tax rate. You cannot pay lower taxes on the new income than on the actual income.

Generally speaking, the more taxes you pay, the higher your marginal tax rate will be. People with low income have a low marginal tax rate, while people with high income have a higher marginal tax rate.

Usually, we compute the marginal tax rate on an increase of 100 CHF or 1000 CHF. The reason is that your marginal tax will increase with higher income. For instance, if the rate is 20% and you get a 10’000 CHF rate, it may be 20% on the first 1000 CHF, but it will likely be more than that on the last 1000 CHF. So, your marginal tax rate is only an estimate for the next increase. But after this, it will change.

## Why is it important?

It is an important metric because it will tell you how much your taxes will increase when you increase your income. And it is essential to know how much more you are getting.

Some people think that by getting a 1000 CHF raise, they can spend an extra 1000 CHF per year. But this is entirely wrong! With a marginal tax rate of 20%, a 1000 CHF raise will only let you spend (or save) 800 CHF more per year. And if your tax rate is higher, it will get even lower.

People are often not considering their taxes when they get a raise. And they end up spending significantly more than the real increase in their income. After-tax income is much more important than before-tax income.

As we will see later, it is also helpful for estimating tax reductions.

## Progressive tax Misconception

The Swiss tax system is generally progressive. It means that high-income people pay a higher tax rate than lower-income people. This is opposed to a system where everyone would pay the same tax rate regardless of income. Most countries are using a progressive tax system.

Since the taxes are different in each canton, some cantons are different. A few cantons use a fixed (proportional) tax rate instead of progressive tax brackets.

Now, there is a common misconception about this system. Many people believe that if you increase your income and end up in a higher tax bracket, you will have less disposable income. It means that your taxes would increase by more than your income.

But in practice, this is not the case (and such a system would not make sense even from a tax point of view). The reason is that once you end up in the next tax bracket, only new income is taxed at this level.

We take an example of a progressive tax system (fictitious):

- 0 CHF to 10’000 CHF of taxable income: 5% tax rate
- 10’000 CHF to 20’000 CHF of taxable income: 10% tax rate
- 20’000 CHF onwards: 20% tax rate

If you earn 5000 CHF, you will pay 5% taxes, 250 CHF. If you earn 9900 CHF, you will pay 495 CHF. If you increase your income by 200 CHF, you will cross into the next tax bracket. But you will not pay 10% of 10’100 CHF (1010 CHF). You will pay 5% of 10’000 CHF and 10% of 100 CHF (10’100 – 10’000 CHF). That is 510 CHF!

The next bracket means that the income in that bracket is taxed at this rate, not your entire taxable income.

## Your marginal tax rate for deductions

A great thing about the marginal tax rate is that it works in two directions. We have seen that it can be used to estimate how much taxes you will pay on extra income.

But the marginal tax rate can also be used for tax deductions. If you reduce taxable income, your marginal tax rate will tell how much you will save in taxes. This is once again an estimation, and for higher amounts of tax reductions, it will be slightly higher than it should be.

If you can reduce your taxable income by 1000 CHF and have a marginal tax rate of 28%, you will save about 280 CHF in taxes! So, a higher rate means you have more opportunities to save money.

This means you can use your marginal tax rate to compute the rate of return of your contributions to the second and third pillars. Other things come into play, of course, but the immediate return is based on the amount of taxes you can save.

## How to compute your marginal tax rate?

Computing your marginal tax correctly is not trivial, but it can be estimated rather easily.

The idea is to compute your current taxes and then do the same calculations again with an added 1000 CHF in income and then check how the taxes increase.

For instance, if you pay 15’000 in taxes per year and pay 15’190 CHF after an increase of 1000 CHF in income, your marginal tax rate is 19% (190/1000).

Now, how do you estimate your taxes? Doing so properly in Switzerland is a bit complicated since each canton has a different way of calculating the taxes.

The most accurate way is to use the actual tax tool of your canton. These tools generally give you an estimate at the end. You can use this estimate with the current income and compare it with the estimate with extra income. This is probably the most accurate method. But it is not the easiest one, and it requires all your information, and you cannot do it for other cantons.

The simplest tax calculator I have found is the tax calculator from talent.com. This tool will even give your tax rate and marginal tax rate. For instance, for a gross income of 160’000 CHF in the canton of Fribourg, the tax rate would be 31.3%, and the marginal tax rate would be 46.9%. This estimate is interesting, but it is very gross and likely overestimated since you need more information to estimate taxes.

A better tax calculator is the calculator from comparis.ch. You will need to give more information, but it will be more accurate. We can take as an example a single-income married couple with no children, a net income of 140’000 CHF for and paying into the third pillar, in the canton of Fribourg. The current taxes would be 22’393 CHF. Adding an extra 1000 CHF to the net income yields taxes of 22’698 CHF. The increase in taxes is 305 CHF. This means a 30.5% marginal tax rate. This is much lower than the estimate of talent.com. It makes sense since this comparator takes into account many more details.

Remember that with these three calculators, your marginal tax rate is still an estimation.

## How to reduce your marginal tax rate?

Reducing your marginal tax rate means reducing your taxes.

In practice, there is nothing specific you can do about reducing your marginal tax rate. The same things you can do to reduce your taxes apply to reducing your marginal tax rate.

Moving to a canton or municipality with lower taxes is the most effective reduction. It is also not something that most people want to do. But geo arbitrage for taxes works well in Switzerland. There are huge differences in the tax rates from one canton to another.

The other way is to reduce your taxable income. For instance, you can deduce your professional fees from your taxable income, food expenses while working, and medical fees. Contributions to the second and third pillars can also reduce your taxable income. There are plenty of other reductions.

If you want more information, I have a guide on taxes and how to reduce them.

## Conclusion

As you can see, your marginal tax rate has several important implications. Once you have a good estimation of this rate, you will know what will happen to any extra income you could get. And you will also know how interesting a reduction in taxable income can be!

Most people have no idea of their marginal tax rate. And there are some misconceptions about how the progressive tax system works. So, it is important to clear out these points.

Hopefully, you should have a good idea of your marginal tax rate and what you can do about it.

Hey, thanks a lot for the blog! It’s extremely helpful! :-)

From my understanding, both average and marginal tax rates should not take into account social contributions (like AHV).

For example, the average tax rate is:

(gross – soc_contrib – net) / (gross – soc_contrib)

where “soc_contrib” are the social contributions.

If this is correct, the calculator from talent.com (https://ch.talent.com/en/tax-calculator) shows higher (and misleading) marginal/average tax rates since it adds up social contributions and taxes to determine the “Total tax” value, which is used to calculate the average and marginal tax rates.

Its average tax rate is:

(gross – net) / (gross)

So, it does not seem the higher values are due to less information than the other calculators, it just looks like the underlying calculations for the tax rates are wrong in this context.

The marginal tax rate from talent.com should also be completely off because of this reason.

Hi Matteo,

Thanks for digging into it!

You are correct that social contributions are not part of what I would call marginal tax rate.

However, they scale with your income, so they are part of your tax burden and higher income will increase it.

The tax rate is subject to interpretation and it could make sense to include the social contributions into the tax rate since it’s a form of tax.

On the other hand, I don’t understand why they would add pension fund contributions as a tax, which several increases the tax rate!

Other than that, they are missing some deductions and result are relatively accurate. Their marginal tax is not too far off at least in my case.

Hi Baptiste,

Thanks a lot for the answer!

I wrote the message since when I tried with my data, talent.com calculated a marginal tax rate of 30%, while the tax calculator from admin.ch (https://swisstaxcalculator.estv.admin.ch/#/calculator/income-wealth-tax) returned 20%, and I was a bit confused.

I saw that the tax calculator from admin.ch makes some assumptions as well (it automatically deduces ~4k because of “other professional expenses, main occupation, Insurance premiums, and interest on savings capital”), but this does not impact my result too much.

I think that if I want to estimate how much I would save with a deduction (e.g., 3rd pillar), it really makes sense to remove all the social contributions first and then calculate the marginal tax rate using the tax rate coming from the taxes only (municipal, cantonal, and federal), found starting from the taxable income. Otherwise, if (like in my case) the social contributions are in the same ballpark as the proper taxes, the result gets really skewed.

In my example, a 3rd pillar would make me save ~20% of the 7k I would put into it, which is 1.4k “only”, as opposed to 2.1k calculated with the 30% that accounts for the social contributions too.

Does it make sense?

Thanks again for the blog; you opened my eyes to many things!

I also think it makes sense to remove the social contributions first adn then compute the marginal tax rate coming from the taxes. But that is not to say that any other interpretation is wrong.

Have you tried using your tax software? I find it the best to compute the marginal tax rate because it takes your personal situation into account. You can take the results from last year, add 1000 CHF in income and see the diffence in taxes. And then, you can reduce your income by 1000 CHf and see the differences in taxes.

I can’t believe that you have an article for every single topic that I google. Incredible, well done 👏 and thank you!

Just wanted to say that I find the Federal Tax Administration calculator useful: https://swisstaxcalculator.estv.admin.ch/#/calculator/income-wealth-tax

Hi Ilias

Thanks for sharing. This calculator is indeed quite good for the federal taxes!

Thanks for your kind words. I am glad you like my articles!

It shows all 3 level of taxes based on ZIP-code, not just the federal one! It’s probably the best calculator, as it’s hosted by admin.ch.

Hello! I was doing some research on the Tax Rates at Talent.com and noticed the Marginal Rates for salaries from 53-59kCHF are significantly larger than for salaries from 60kCHF-99kCHF.

Is this normal behaviour?

Hi Eduard,

I don’t think it’s normal behavior, no. For me, this seems like a bug from the calculator.

For which canton are you testing?

Thanks for the article, I really like the topic!

But, are you sure that “The next bracket means that the income in that bracket is taxed at this rate, not your entire taxable income.”?

I have bexio accounting software and I can see that the entire income is always taxed at the same rate (not chunked), at least that is how it works for Zurich. I was experimenting a bit and in some edge cases, it can even happen that increasing income by 1 CHF will result in you getting 100 CHF less after taxes.

Wouldn’t it be extremely impractical to split the salary in chinks when calculating it? For a salary of 10’000 CHF, there are exactly 185 brackets until reaching the final one of 11.15% for ZH.

Hi Miro,

I am almost sure about that. I would be surprised if 1 extra CHF would yield a lot of difference. It’s possible that the accounting software is not absolutely accurate.

It’s done by a computer, so there is nothing impractical about it.

Now, I don’t know all cantons and their tax systems, there way be some weird things going on.

> I was experimenting a bit and in some edge cases, it can even happen that increasing income by 1 CHF will result in you getting 100 CHF less after taxes

This cannot be the case – that’s not how swiss taxes work. Just use an official calculator instead. Adding 1CHF should always increase your taxes by <1CHF.

https://swisstaxcalculator.estv.admin.ch/#/calculator/income-wealth-tax

I do agree that the italent.com calculator is somewhat oversimplified. In fact, I think it is so to the point of being misleading!

Right up front, it asks for your income and not your taxable income.

They are indeed trying to make it simple and this leads to making it less accurate :)

but let’s remember that paying taxes is also an act of solidarity towards the rest of the population. we certainly don’t want to be like in the USA where rich can pay 0 by doing charity or even getting money back like amazon with very doubtful financial acrobacies

Hi Karl,

I agree that the rich should pay more than the poor in order to have a balance.

Sometimes however I wish that we would be a little less social in Switzerland.

But taxes are relatively fair.

Thanks for stopping by!

Thanks for explaining so clearly! Great post
