The Home Office deduction can provide tax benefits for both employed and self-employed individuals working from home. However, specific requirements must be met, and eligibility can vary based on individual circumstances and canton-specific regulations.

What Are the Requirements?

To claim a Home Office deduction, the following conditions must be satisfied:

1. Exclusively Work-Related Space: The office must be a dedicated, permanent area used solely for work purposes. Shared or multipurpose spaces, such as guest rooms, are typically ineligible. For example, if the space doubles as a guest room for even a short period (e.g., two weeks per year), the deduction may be disallowed.
2. Essential and regular activity in the home office (canton-specific regulations vary: generally at least 1/3 to 40% of working time)
3. Employer Workspace not provided: The employer does not provide the employee with a workplace, or its use is unreasonable or not feasible;
4. Evidence: Tax authorities may request photographs or other documentation to confirm the space’s exclusive use for work.

The Home Office deduction cannot always be claimed, even when no dedicated workspace is provided to the employee. For example, we handled a case where a multinational corporation declined to issue the required letter, citing that the employee technically had access to conference rooms, despite not being provided with an actual workspace.

Calculation for Rent or Ownership

The basis for calculating the deduction differs depending on whether you rent or own your home. This example is for the canton of Zurich:

• Renters: The deductible amount is calculated as:
  Total Rent ÷ (Number of Rooms + 1)
  This formula accounts for shared spaces such as kitchens or common areas. If there is an obvious imbalance the proportional surface area will be taken into account.
• Homeowners: The calculation is based on the Eigenmietwert (the imputed rental value of the property) instead of actual rent payments.

Lump-Sum Deductions: A Streamlined Alternative

In many cases, opting for the lump-sum professional deductions provided by tax authorities is more advantageous. This approach simplifies the process and reduces scrutiny over individual claims. During the pandemic, the general rule was to default to standard deductions for travel and lunch expenses, with Home Office deductions granted only in specific circumstances.

In the Canton of Zurich, typical lump-sum deductions include:

• General professional expenses: CHF 2,000 – 4,000
• Travel costs: CHF 1,020 – 3,890
• Lunch expenses: CHF 0 – 3,200

Claiming lump-sum deductions often results in comparable or better tax benefits than itemizing actual Home Office expenses. On average, taxpayers can deduct between CHF 7,000 and 8,000 using standard deductions—equivalent to the deduction for a CHF 2,800 rent on a 3.5-bedroom apartment.

What Expenses Are Deductible for a Home Office?

For those eligible to claim the deduction, the following costs can typically be included:

• Rent for the designated office space (or Eigenmietwert for homeowners).
• A proportionate share of internet and telephone costs.
• Other minor side costs, as reasonable, such as electricity, heating, and water.

Tip: It’s best to estimate modest amounts for utilities and side costs to avoid the need for extensive documentation, such as invoices and prorated calculations.

What Happens If the Deduction Is Disallowed?

If your Home Office deduction is denied, there’s no need to worry. The generous lump-sum professional deductions available in Zurich often provide comparable or better benefits without the added complexity. Additionally, filing with lump-sum deductions generally speeds up the tax assessment process.

Should You Claim a Home Office?

While a Home Office deduction may seem appealing, it is not always the most advantageous choice. Consider the following:

1. Be Honest: If you work exclusively from home, ensure you don’t claim travel or lunch expenses that wouldn’t apply.
2. Evaluate Your Situation: Lump-sum deductions may offer better financial outcomes while simplifying your return.
3. Seek Professional Guidance: Tax rules can be complex, and regulations vary by canton.
