# Subletting Second Hand: Tax Rules and Declaring Your Rental Income *21 juni 2026* > Subletting your property can provide extra income, but understanding the tax implications is crucial. This guide explains how to declare your rental income and the deductions you can make to minimize your subletting tax. Subletting your property can be a smart way to earn extra money, but it's essential to understand the tax rules. This guide provides a detailed walkthrough of how to declare your rental income and the deductions you can make to reduce your tax burden. Understanding **subletting tax** is crucial to avoid issues with the tax authorities. ## Understanding Taxation of Second-Hand Rentals When you sublet your property, you typically need to pay tax on the portion of the rent that exceeds a certain threshold. The rules can differ depending on whether you are subletting a house, a condominium (bostadsrätt), or a rental apartment (hyresrätt), and whether the subletting occurs in Sweden or abroad. Generally, the part of the rent exceeding the operating costs is taxed. ### Step 1: Identify Your Taxable Income The first step is to calculate how much of your rental income is taxable. Here are the basic principles: * **Condominium (Bostadsrätt) and House (Villa):** You can make a standard deduction. For the entire property, the deduction is SEK 40,000 per year. If you sublet only a part of the property, such as a room, the deduction is SEK 20,000 per year. The rent exceeding this amount, plus the actual operating costs for the sublet portion (if renting out a room), is taxable. * **Rental Apartment (Hyresrätt):** For a rental apartment, you can make a standard deduction of SEK 40,000 per year. The rent exceeding this amount is taxable. It's important to note that these amounts apply to the entire year. If you only sublet for a portion of the year, the deduction is calculated proportionally. ### Step 2: Calculate Deductible Expenses In addition to the standard deduction, you may also be entitled to deduct certain actual expenses. These expenses must be directly related to the subletting. * **For Condominiums and Houses:** You can deduct the portion of ongoing costs attributable to the sublet part. This includes, for example, the fee to the housing association, loan interest, property tax, electricity, water, and heating. For a whole property, you can deduct 50% of these costs. If you sublet a room, you can deduct the actual cost of the room, plus a proportional share of the common costs. * **For Rental Apartments:** You cannot deduct any actual expenses beyond the standard deduction. ### Step 3: Fill Out Your Tax Return Once you've calculated your taxable income, it's time to declare it. This is done on your regular income tax return. * **Digital Tax Return:** Log in to the Swedish Tax Agency's e-service "Mina sidor" or "Inkomstdeklaration." You will find a specific section for declaring capital income, where you enter the details of your subletting. You need to specify the portion of the year the property was sublet, the total rental income, and any deductions. * **Paper Tax Return:** If you are filing a paper return, find the correct section for capital income and fill in the corresponding information. You will need to provide: * Property details or information about the condominium. * Total rental income during the year. * Any deductions (standard and/or actual expenses). It is crucial to be precise when entering the information to correctly declare the rental income. ### Step 4: Handling Different Types of Subletting The rules for **tax on rental income** can vary slightly depending on how you sublet: * **Subletting an entire property:** The standard and expense deductions described above apply. * **Subletting a part of a property (e.g., a room):** For condominiums and houses, you can deduct SEK 20,000 as a standard deduction, plus the actual costs for the sublet part. For rental apartments, the same standard deduction applies as for whole-property subletting, but you cannot deduct actual costs for the room. * **Short-term rentals (e.g., via Airbnb):** Short-term rentals are also considered subletting and must be declared. The rules for standard deductions and expense deductions are the same as for longer-term sublets. ### Step 5: Exceptions and Special Cases There are certain situations where the rules differ: * **Subletting to a relative:** If you sublet to a relative (spouse, cohabitant, child, parent), you cannot claim any deductions. The entire rental income becomes taxable if it exceeds a market-rate rent. * **Subletting a holiday home:** The rules are similar to those for permanent residences, but with different deduction amounts. * **Subletting abroad:** If you sublet a property abroad, the tax rules of that country apply, but you may also need to report the income in Sweden. Double taxation treaties can affect how the tax is calculated. ### Step 6: Common Mistakes to Avoid Failing to declare subletting is a common mistake that can lead to tax penalties. Other frequent errors include: * Not distinguishing between taxable and non-taxable rent. * Deducting expenses not directly related to the subletting. * Forgetting to claim the standard deduction. Understanding **subletting tax rules** is key to a correct tax return. ### Step 7: Preparing for Your Tax Return To simplify the tax filing process, it's advisable to: * Keep all agreements and receipts related to the subletting. * Maintain a simple record of rental income and expenses. * Familiarize yourself with the Swedish Tax Agency's information on subletting. ### Summary Subletting can be profitable, but it requires you to understand the **subletting tax rules**. By carefully calculating your taxable income, deducting eligible expenses, and accurately completing your tax return, you can avoid unnecessary penalties and maximize your net income. Remember, the entire process involves correctly reporting your income to the Swedish Tax Agency. ### FAQ ### What is market-rate rent? Market-rate rent is the rent you could achieve if you sublet the property on the open market to an unrelated person. The Swedish Tax Agency considers similar properties in the same area when determining market-rate rent. If you sublet to a relative and the rent is significantly lower than market rate, the Tax Agency may consider the difference a gift, making it taxable. ### How do I declare if I'm subletting a room? If you sublet a room in your condominium or house, you can claim a standard deduction of SEK 20,000 per year. Additionally, you can deduct the actual costs for the room, as well as a proportional share of the common costs for the property (electricity, broadband, etc.). For rental apartments, the same standard deduction applies, but you cannot deduct actual costs for the room. ### How long can I sublet tax-free? You can sublet your condominium or house for up to SEK 40,000 per year without paying tax on the rental income, provided you claim no other deductions. For rental apartments, the same standard deduction applies. However, this is not tax-free in the sense that you don't need to declare it; it's a portion of your income that is not taxed. For rental apartments, only the standard deduction amount is effectively tax-free.
