Your first 90 days: the financial setup that changes when you move

Congratulations on the Swiss salary. Now build the machine around it.

A job offer gives you one beautifully clean number: salary. Real life then adds tax collection, payroll deductions, health insurance, accident cover, pension contributions, rent timing and whatever financial baggage you brought across the border. The first three months are less about "admin" than learning how the machine works.

The rule is simple: do not optimise a financial setup you cannot yet explain. Build the baseline first. Fancy decisions can wait their turn.

1. Month one can feel expensive even when the move is affordable

A perfectly sensible annual budget can still get mugged by month one. A residential rental deposit can be as much as three months' rent, and it may arrive alongside first rent, temporary accommodation, travel, furniture and moving costs — all before your salary rhythm feels normal.

Treat that as a timing problem, not automatically a lifestyle problem. Ask: "How much liquid cash do I need to reach the first boring, repeatable month?" Boring is good here. Boring means the system has settled.

2. Gross salary is the headline. Household cash flow is the story.

Payroll removes several items before the money reaches you. But it does not remove everything. Basic health-insurance premiums are generally paid separately. Tax may be withheld at source or handled through ordinary assessment. Pension and accident deductions vary by employer and plan. The number on the contract is therefore not the number your household can spend.

A useful baseline has two columns: what payroll already dealt with, and what still needs paying afterwards. If those two columns are not clear, "net salary" can create more confidence than clarity.

3. Know what payroll handles — and what it politely leaves to you

Social-insurance contributions are largely handled through payroll. Basic health insurance is different: residents generally arrange it themselves within the applicable three-month window. Accident cover splits again: employees are covered for occupational accidents, and those working at least eight hours per week for the same employer are also covered for non-occupational accidents.

That can create a small but useful saving: if you have full occupational and non-occupational accident cover through work, you can apply to suspend the accident component of basic health insurance. If you are not working, or are below the threshold, the health-insurance setup can be different. Same address; different answer.

4. Tax deducted is not the same thing as tax understood

For many foreign employees without a C permit, tax is deducted at source. C-permit holders generally file under ordinary assessment, and some people initially taxed at source can enter or request ordinary assessment depending on their circumstances. Convenient collection is not the same as a final tax conclusion.

Before asking "How do I reduce my tax?", ask three less glamorous questions: Which regime am I in? Which canton is responsible? Do foreign income or assets create additional filing issues? Clarity first. Optimisation after.

5. Your old financial life did not evaporate at customs

Bank accounts, brokerage accounts, property, pension rights, stock plans and insurance policies can remain abroad after you move. Their treatment depends on Swiss rules, the other country's rules and any relevant tax or social-security agreement. Cross-border finance is where confident guessing becomes expensive.

Keep a one-page inventory: what exists, where it sits, what country is involved, and who can answer the country-specific question. The objective is not to move everything. It is to stop anything important becoming invisible.

6. The day-90 test: can you explain the setup on one page?

By roughly three months, you should be able to write down your normal take-home pay, tax method, health-insurance premium, accident-cover setting, pension fund, previous pension assets and main foreign financial items — plus the next dates that matter. If the answer requires opening twelve PDFs, the baseline is not finished yet.

Navinua rule — The paperwork is evidence. The one-page baseline is the operating system. If you cannot explain the setup simply, you do not yet control it.
