Who Pays the Serafe Bill in a WG (Shared Apartment)?
Moving into a Swiss WG (Wohngemeinschaft) is a rite of passage for most expats, but the first time a CHF 335.50 bill from Serafe arrives addressed to just one person for the entire flat, the honeymoon phase ends quickly. I remember my first month in Zurich, staring at that invoice while my three roommates argued over who was legally responsible for the "radio and TV tax" when half of us didn't even own a television. This guide untangles the legal liabilities, payment split strategies, and exemption rules for shared households to ensure your living situation remains harmonious.
Understanding the Serafe Household Logic
The most important thing to wrap your head around is that Switzerland moved away from a "per device" fee years ago. It doesn’t matter if you have five televisions or zero smartphones; the fee is a flat-rate mandatory contribution for every private household in the country. In a shared apartment, the law views the collective group of people registered at that specific address as one "household unit." This is often a point of contention for expats who are used to paying for what they use, but in the Swiss system, the bill is simply part of the Cost of Living in Switzerland 2026: Budgeting for Singles and Families.
Serafe, the company responsible for collecting this fee, receives its data directly from the cantonal and communal population registers. When you went through the process of Registering Your Address at the Kreisbüro Within 14 Days of Moving, your name was added to a database linked to your specific apartment number. Serafe looks at that list of names, picks one person seemingly at random, and sends them the bill for the entire year. If you are the "lucky" one whose name is on the envelope, you are the person Serafe holds primary responsibility for, regardless of how many other people are eating your yogurt in the kitchen.
Why Only One Name Appears on the Bill
It is a common misconception that the bill should be split by the authorities before it reaches your mailbox. Serafe does not care how you divide the money; they only care that the CHF 335.50 reaches their account. They designate one person as the "representative" of the household. If you are living with three other people, you aren't paying four times the amount; you are paying one fee collectively. Understanding this is crucial for Budgeting in Zurich and Geneva: Managing Expat Expenses in High-Cost Cities, where every franc counts.
The Concept of Solidary Liability
This is the part that catches many foreigners off guard. Under Swiss law, all adult members of a household are "solidarily liable" for the Serafe fee. This means that if the person whose name is on the bill refuses to pay or leaves the country without settling the debt, Serafe can legally pursue any other person registered at that address for the full amount. You cannot tell the debt collection office, "I paid my 25% share to my roommate." If the total isn't paid, everyone is on the hook. This is why it is essential to manage your shared finances through a transparent system, perhaps utilizing Banking and Finance for Expats in Switzerland: The 2027 Guide to set up a shared "house account."
Managing the Split and Internal Payments
Once the bill arrives, the person named on the invoice usually has 30 days to pay. In a functional WG, the person who receives the bill will message the group chat and ask everyone to send their share via TWINT or a bank transfer. If you are the one receiving the funds, you might find it useful to keep the household's "Serafe fund" in a separate pot. Some tech-forward roommates even use platforms like Trade Republic to hold collective savings for annual bills like this, allowing the money to earn a bit of interest before the invoice is actually due.
Methods for Fair Distribution
There are generally two ways WGs handle this. The first is the "On-Demand" method, where the person billed pays the full amount upfront and then "bills" their roommates for their shares. This requires the person named on the invoice to have enough liquidity to cover the CHF 335.50 initially. For international students or those just starting out, this can be a stretch.
The second method is the "Monthly Reserve." Many WGs add a small "Serafe line item" to their monthly communal expenses (Nebenkosten). If you have four roommates, each person contributes roughly CHF 7 per month to a shared kitty. By the time the annual bill arrives, the money is already there. For roommates who are moving from abroad or traveling frequently, using a service like Wise to transfer these small monthly amounts into a Swiss account is a great way to avoid the high fees associated with traditional banks.
| WG Member Status | Typical Share | Responsibility |
|---|---|---|
| Main Tenant | 1/N of total | Often the default name on the Serafe bill. |
| Subletter | 1/N of total | Legally liable even if not on the main lease. |
| Short-term Guest | 0 | Not liable if stay is under 3 months and not registered. |
| Student (B Permit) | 1/N of total | Usually no exemption unless receiving specific Swiss social aid. |
Handling Roommates Who Refuse to Pay
It happens more than you’d think—a roommate moves out in a hurry or claims they "don't watch Swiss TV" and therefore shouldn't pay. Because of the solidary liability mentioned earlier, the remaining roommates must cover the deficit to avoid a "Betreibung" (debt enforcement) against the person named on the bill. If you find yourself in this situation, you have a civil claim against the non-paying roommate, but Serafe will not get involved in your internal dispute. They want their money, and they don't care which of you it comes from.
Exemptions for Shared Households
A frequent question I get is whether students or low-income earners can get out of paying the fee. The rules are quite strict. Exemptions are generally only granted if someone in the household receives supplementary benefits (Ergänzungsleistungen) to their AHV or IV (pension or disability insurance). If you are a student living with a working professional, the household as a whole must pay. There is no "pro-rata" discount just because one person is broke.
Mixed Households of Students and Professionals
In a mixed WG, the bill is still CHF 335.50. It doesn't matter if three out of four people are PhD students with no income; if the fourth person is an investment banker, the household is treated as a single taxable unit. You might want to read up on Can University Students or Welfare Recipients Get a Serafe Exemption? to see if your specific combination of roommates qualifies for any niche cantonal breaks, though they are increasingly rare.
One interesting scenario I encountered in Geneva involved a roommate who was a diplomat. Members of foreign missions who enjoy diplomatic status may be exempt from the fee. However, if they live with non-diplomats (like a regular expat), the exemption usually only applies to the diplomat's portion, or in some cases, the entire household fee is still due because a "liable person" lives there. Always check with your local "Office de la population" if you are in a specialized visa category.
The "No-Device" Myth
You might hear old-timers talking about an "Opt-out" for people without radios or TVs. That transitional period ended in 2021. Today, the only way to be exempt for having "no receiving devices" is if you genuinely have no smartphone, no tablet, no computer, no car radio, and no television. It is virtually impossible for a functioning adult expat to prove they have zero access to any device that can stream or receive a signal. Serafe assumes you have a device, and the burden of proof is on you to prove otherwise—a process that involves a physical inspection of your home.
Moving In and Moving Out: The Pro-Rata Headache
The timing of the Serafe bill is rarely aligned with your move-in date. If you move into a WG in July, but the bill arrived in January and was paid for the whole year, what do you owe? Legally, Serafe bills in advance for a 12-month period. If you join a household midway through the billing cycle, it is common courtesy (and standard practice) to pay your pro-rata share to the roommate who already covered the invoice.
Settling Up When Someone Leaves
When a roommate moves out, they often forget about the Serafe fee they "pre-paid" for the remaining months of the year. If you are Leaving Switzerland Financially: Closing Accounts and Pension Payouts, don't forget to ask your roommates for a refund of your unused months, or simply agree that the incoming "Nachmieter" (replacement tenant) will buy out your share.
If the person whose name is on the bill moves out, you must notify Serafe—or rather, the commune—of the change. Usually, the system handles this automatically when the person registers their departure. The bill will then be re-issued to one of the remaining residents. I’ve seen cases where a WG received a final bill for the departing roommate and a new bill for the remaining ones within the same month. If this happens, do not ignore it. Check the dates carefully; they should not overlap.
Registering the Change of "Head of Household"
If you were the one paying the bill and you are moving to a new apartment or leaving Switzerland, ensure your roommates know who will be taking over the administrative burden. You can actually log into the Serafe portal and suggest a different "representative" for the household, though they often just default to whoever has lived there the longest or whose name appears first alphabetically from the commune's list. Keeping your records updated is just as important as Filing a Swiss Tax Return (C Permit or High Earners on B Permit) to avoid administrative chaos down the road.
Strategies for a Stress-Free WG Finance System
To avoid the yearly "Serafe scuffle," I highly recommend having a dedicated digital space for your household finances. Whether it's a simple Google Sheet or a shared app, transparency is the enemy of resentment. One WG I lived with in Lausanne was incredibly organized—we had a "digital wallet" where we tracked everything from bin bags to the Serafe bill. One roommate was particularly into crypto and would even settle his share by checking the latest rates on Binance and sending the equivalent in Swiss Francs to our shared bank account.
Shared Accounts vs. Individual Responsibility
While one person is legally the "face" of the bill, the most successful WGs treat the Serafe fee as a utility, like electricity or internet. If you can, set up an "eBill" within your Swiss banking app. This allows the invoice to appear digitally, where it can be easily screenshotted and shared with the group. It also prevents the physical paper bill from getting lost under a pile of pizza menus in the hallway.
When you see the deduction for Understanding Swiss Payslips: Deductions for AHV, ALV, and NBU, you realize how much the Swiss love their mandatory contributions. The Serafe fee is just the household version of that. By automating the payment and using How to Set Up and Use the TWINT Payment App as an Expat to collect the shares instantly, you remove the emotional weight of the "big bill."
What to Do If You Get Two Bills
Occasionally, the system glitches. If you and your roommate both receive a bill for CHF 335.50 for the same period and the same address, do not pay both. This usually happens when the commune's database hasn't correctly "linked" your names to the same apartment number (e.g., one is listed as "Appt 4" and the other as "4th Floor"). Call Serafe immediately. They are actually quite helpful on the phone and can merge the accounts. You will need to provide both billing numbers and the names of everyone in the WG.
