Ok, seems I'm one of many who have too much time on my hands this morning. To be honest I started to pen this a couple of hours ago and have not bothered to read what else is posted, so this may contain some repetition of what is there and also what is in the stickies. But anyway....
Personal taxation is confusing for many of us foreigners, both due to the way it is presented and collected. The following is an attempt to clarify in some detail, further information (Zurich specific, but in English) can be found at this link
http://www.steueramt.zh.ch/html/engl...tax_system.htm
Firstly, many people reading will be on source tax (Quellensteuer), whereas most of what is written below relates to the normal tax system. I think it’s worth a read anyway, but if you like skip to the source tax bit near the end.
It may be helpful to consider a matrix, where on one axis you have the different categories you are being taxed on (income, interest on investments, wealth, withdrawals from pension related schemes, lottery wins etc) and the other axis you have the different authorities who are levying the taxation. Each tax category can be taxed differently by the different authorities.
Keeping it simple lets consider just income tax for a private (Natürliche) person. You will be required to pay tax based on your ‘taxable income’ (Steuerbares Einkommen) to 3 authorities, Federal Government (Direkte Bundesteuer), Canton (Staatssteuer) and local community (Gemeindesteuer). You may also be required to pay tax to the church (Kirchensteuer).
Firstly taxable income is the portion of the gross income, after deduction of pension (BVG) contributions and various other allowances. Typically taxable income may be of the order of 90% of gross, but of course this can vary in individual cases (married, single, level of BVG contribution etc) according to the deductions. Note that the taxable income may be slightly different when calculating Direkte Bundesteuer compared to Staats and Gemeindesteuer as the rules for allowable deductions are slightly different.
The Bundesteuer is levied everywhere to everyone at a rate determined by the Federal Tax Authority (Eidgenössische Steuerverwaltung). The amount you will be liable for is calculated according to your level of taxable income cross-referenced with a lookup table (different according to marital status) of finely grained taxation levels, which can be seen at
http://www.steueramt.zh.ch/html/steuerfuesse/index.htm#
From this table you can easily see that the Direkte Bundesteuer for a taxable income of 92,000 for a single person is calculated as:
rate for 90,000 = 2430.15
plus additionally (92000-90000)/100 x 6.60
= total of 2562.15 = 2.78%
The Staats and Gemeindesteuer are more complex beasts. Firstly, the rules and rates are different depending exactly where you live (Canton, Town). What I say here relates to the treatment in Zurich, it may vary elsewhere.
Firstly there is the concept of basic Cantonal tax (einfache Staatssteuer). You don’t actually pay this, rather you will pay percentages of this. This basic tax is calculated according to another lookup table, which is revised periodically. For Zurich the same figures have been used since 2006, and can be found at
http://www.steueramt.zh.ch/html/steuerfuesse/staatssteuertarife.htm#
Again, assuming the same 92,000 income for a single person (GT rates, married person uses VT rates) we see the basic tax is calculated as:
rate for 67,300 = 3564
plus additionally (92000-67300)/100 x 9
= total of 5194.2 = 5.65%
As stated, you do not directly pay this. What you will pay is a percentage of this figure to the Canton, and a further percentage of it to the local community.
In Zurich, the Cantonal rate is currently 100% of this basic tax. Depending on which local community you live in (Zurich City, Wintherthur, Thalwil etc) the community rate is a different percentage which can vary wildly e.g. Wintherthur is 122% whilst Thalwil is 80% (full list for Zurich at
http://www.steueramt.zh.ch/html/steu...euerfuesse.htm). Your total Staats-Gemindesteuer rate is then sometimes referred to as a sum of these e.g. 100% + 122% = 222%.
In our example, assuming our single person earning a taxable salary of 92,000 lives in Winterthur and doesn’t pay church tax, he will actually be required to pay a total of 222% x 5194.2 = 11531.12 = 12.53% as Staats-Gemindesteuer in addition to the previously calculated Bundesteuer, which gives a total tax-take of (11531.12 + 2562.15) = 14093.27 = 15.32%.
If that same person changes job and is now paid a taxable salary of 200,000 the figure changes dramatically to
Bundesteuer 14288.15
Staats-Gemeindesteuer 17527 * 222% = 38909.34
Total : 41,472.09 = 20.74%
So it starts to become clear that the amount of tax varies considerably according to income level and location. Also notable in an example from Zurich tax authority is that a single person earning 124,500 will have a basic Cantonal tax similar to a married person earning 200,000. When you consider that the Staats-Gemeindesteuer paid is actually up to 222% of this, you can see that a single high earner will be paying a lot more in tax than a married average earner.
As for collection of tax, you will receive communication both from the Bundesteuer people (Federal tax authority) and the Staats-Gemeindesteuer people (Cantonal tax authority). However, all payment will be made to the Cantonal tax authority, who then distribute to the Federal authority the amount they are entitled to.
The figures from the Cantonal tax authority only include what is due to them. As you pay money to them (either quarterly in advance as recommended, or however you like to do it) they will pass on to the Federal authority what is owed to them.
This can lead to a situation where e.g. Federal authority asks for 5,000, Cantonal separately asks for 15,000, you pay the Cantonal authority 15,000 and you later get a letter from the Cantonal showing they passed 5,000 to the Federal authority and you have therefore underpaid the Cantonal authority by 5,000. Again, a little confusing for Johnny foreigner. And depending when you file your taxes and the speed of your Cantonal authority this can be 2 years after you earned the taxable income.
As mentioned at the start, there are various 'taxable objects' (income, wealth, rent-equivalence etc) all of which are added together into the tax filing and managed via the Cantonal tax authority. We focussed just on the income aspects above.
Now, all this is wonderful, but how does it relate to foreigners living here on residency permits and are required to pay source tax (Quellensteuer). Well, firstly, what is Quellensteuer. Actually, it is in a sense a witholding tax on income in lieu of normal income tax.
What this means is that your employer must withold a percentage of your monthly salary to pay to the tax authorities. Each paycheck will have a certain gross value (maybe it’s constant, maybe it changes each month depending on the amount of work you do, or if you are paid a bonus, etc). This gross value is looked up in another wonderful table (e.g. for Zurich, the current rate is unchanged since 2008 and for single persons can be found at
http://www.steueramt.zh.ch/html/steu...if_a_QSt08.pdf) . The amount determined from this table is then witheld as Quellensteuer and paid to the Cantonal tax authorities.
The Quellensteuer table is calculated based on Staats-Gemeindesteuer tax rates averaged across the various Gemeinde rates within the Canton. What this means is that depending on where you live in the Canton, you may be paying more or less in Quellensteuer than you would if you explicitly paid Staats-Gemeindesteuer.
Also, as this is calculated per month on the basis of the amount in that months paycheck, uneven earnings lead to inappropriate deductions in some months. For example, it is common here to be paid 1/13th of your gross salary each month Jan.-Nov. then paid 2/13th in December. This means your December paycheck is twice the normal size, which pushes you further into the big lookup table, thus invoking higher levels of marginal tax. You can find a very large part of the 2nd 1/13th wiped out by Quellensteuer.
To correct for this, and other anomolies (like wealth tax etc) you may be required, depending on your Canton, your status (permit type), salary level etc. to file a separate tax return so that the normal taxes as above can be calculated. If there is a difference between that and the amount of source tax paid, this difference will be requested/refunded.
Additionally, I believe in most Cantons (if not all) you can request to file for normal taxes, or at least make application for adjustments (e.g. if you pay into 3rd pillar, you will want a portion of your Quellensteuer refunded).
So, in summary, the much talked about ‘10% taxes in Switzerland’ can be a reality for some (lower earners who are married with kids), but for single high earners is something of a myth (although to be fair, compared with most other countries they are relatively low even for these).
For such people hit with higher taxes, there are at least some options here. For a start we have approx. 6,500 that can be paid into 3rd pillar savings each year. That amount can be deducted from taxable salary, saving maybe 1-2k in tax according to your tax rate (there’s a space in the annual tax return to report this). If you are not part of an employer pension scheme (2nd pillar, BVG) you can pay up to approx. 35k into 3rd pillar. For those with BVG you may (depending on your scheme, insured salary level, previous contributions, previous withdrawals, when you came to Switzerland etc.) be able to make additional BVG contributions (purchase of missing years). Again the amount paid into BVG is deducted from your taxable salary so providing immediate tax savings. Of couse, 2nd and 3rd pillar have restrictions and separate taxation arrangements if you wish to withdraw this money at a later stage.
Hope it was helpful, and answers at least some questions. More importantly it gave me something to do on a quiet Wednesday morning and almost felt theraputic.
