Owning rental property in Denmark comes with a specific set of tax rules that differ significantly from how shares or business income are treated. Understandably, that surprises many investors, because property combines several separate tax regimes at once: your letting income and the deductions you can offset against it, a flat tax on any eventual gain, an annual tax on the assessed value of the property itself, and a council-level property tax on top. Getting these right is not optional — SKAT has access to rental contract data and cross-references it, so errors surface quickly. This guide walks through each layer for a Denmark-based property investor, from declaring rental income to calculating capital gains when you sell. It is educational rather than tax advice, and the figures reflect rates as published in 2026.
How rental income is taxed
Rental income from Danish property is classified as indkomst af ejendom (income from property) and is taxed at your marginal tax rate. For most high-income earners, this means a combined rate of up to 52.5% — the top marginal rate includes the 8% labour market contribution (AM-bidrag), so the headline number is substantially higher than the corporate or capital gains rates you encounter elsewhere in the tax system.
You must declare all rental income on your annual tax return, regardless of whether you live in Denmark or abroad. Rental income includes more than the monthly rent:
- Monthly rent received from tenants
- Any fees paid directly by tenants to you (for example, for parking or storage)
- Compensation for early lease termination
A key point
Even if you use a property management company, you remain responsible for declaring the income and paying the tax on it. Delegating the day-to-day management does not delegate the liability — so keep your own records of rent received and expenses incurred, even when a manager handles the tenancies.
Deductible expenses
Denmark allows property investors to deduct a range of expenses against rental income, which can substantially reduce your tax bill. The main deductible items include:
Mortgage interest (rentefradrag)
Interest paid on loans secured against the rental property is fully deductible against rental income. It is one of the most significant deductions available to property investors, and the benefit is especially valuable for newly purchased properties, where interest payments are front-loaded in the early years of the loan.
Maintenance and repairs
Reasonable costs for maintaining and repairing the rental property are deductible. This includes:
- Plumbing and electrical repairs
- Painting and decorating between tenancies
- Roof repairs and gutter cleaning
- Replacing broken fixtures and fittings
Note: improvements that add value to the property — such as adding an extension or installing a new kitchen — are generally not deductible as maintenance. They are added to the acquisition cost instead, which matters for capital gains when you eventually sell.
Property management fees
Fees paid to a property management company are fully deductible. This covers rent collection, tenant screening, handling maintenance requests and managing legal compliance. If you are weighing hiring a manager, the annual fee is at least softened by the tax deduction.
Insurance
Building insurance and landlord liability insurance premiums are deductible expenses.
Depreciation on buildings
You can depreciate the building value (not the land) at up to 4% per year on a declining balance basis. This is a valuable deduction that reduces taxable rental income each year even though it is a non-cash expense. Land cannot be depreciated — only the structure — which is why the building value and land value matter separately for your books.
Capital gains on rental property
When you sell a rental property at a profit, the gain is subject to ejendomsavancebeskatning (property capital gains tax) at a flat rate of 42%. Note the contrast: your rental income is taxed at marginal rates of up to 52.5%, but the eventual capital gain — often the largest single profit in a property’s financial life — is taxed at a flat, and lower, 42%.
How the gain is calculated
Gain = Sale Price − Acquisition Price (adjusted for indexation)
The acquisition price is adjusted based on the retail price index (forbrugerprisindex) from the year of purchase to the year of sale. This indexation accounts for inflation and can reduce the taxable gain considerably, especially for properties held over a long period — a meaningful portion of any nominal price rise may simply reflect general inflation rather than a real profit.
Example calculation
| Item | Amount |
|---|---|
| Purchase price (2015) | DKK 3,000,000 |
| Index-adjusted acquisition cost | DKK 3,450,000 |
| Sale price (2026) | DKK 4,200,000 |
| Taxable gain | DKK 750,000 |
| Tax at 42% | DKK 315,000 |
Main residence exemption
If the property was your main residence (bolig) for part of the ownership period, the gain on that portion is tax-free. This is one of the most valuable exemptions in the Danish property tax system, and it is the reason a property’s history matters as much as its price.
How it works
- You must have lived in the property and used it as your primary residence for part of the time you owned it.
- The gain is apportioned based on the fraction of time the property was your main residence versus a rental or investment property.
- The exemption only applies to the period you actually lived there — you cannot claim it for a property you never occupied.
Example: if you owned a property for 10 years and lived there for 4, then 40% of the gain is tax-free. The remaining 60% is taxed at 42%.
Summer houses (sommerhus)
A summer house is taxed at 42% on any gain when sold. The main residence exemption generally does not apply to summer houses unless you lived in one as your primary residence — which is rare. So the tax shelter available on a main home is absent here, and purchase and sale costs matter more relative to the net gain.
Some owners let a summer house for part of the year. In that case:
- Rental income is taxed at your marginal rate
- Capital gains are taxed at 42%
- Deductible expenses are limited compared with a full rental property
Ejendomsværdiskat (property value tax)
This is a tax on the assessed value of all property you own in Denmark. It is calculated as follows:
| Value Threshold | Rate |
|---|---|
| Up to DKK 3,040,000 | 0.92% |
| Above DKK 3,040,000 | 3% |
A DKK 700,000 reduction applies to your main residence, meaning the first DKK 700,000 of your primary home’s value is exempt. For investment properties — where you do not live — no reduction applies, so the full assessed value is subject to ejendomsværdiskat. It is an annual holding cost that should be factored into any cash-flow projection alongside the mortgage, not an afterthought.
Ejendomsskyld (municipal property tax)
Ejendomsskyld is a separate property tax paid directly to your municipality. It is based on the property’s vurdering (assessment value) set by the Danish Tax Agency (SKAT). Rates vary by municipality but are generally lower than ejendomsværdiskat.
One useful distinction: ejendomsskyld is deductible against rental income, unlike ejendomsværdiskat, which is not. When you are comparing two otherwise similar properties, checking the local ejendomsskyld rate is worthwhile because it differs across municipalities.
Letbolig (leased land)
Letbolig refers to a property where you own the building but lease the land underneath from a landowner — often a municipality or private landlord. This arrangement is common in certain parts of Denmark and has its own tax treatment.
Tax treatment
- You can depreciate the building value, even though you do not own the land
- When you sell, the gain is taxed at 42% on the building only
- The lease payments (ground rent) may be deductible against rental income
- There is no ejendomsværdiskat on the land component, since you do not own it
Letbolig can be a more tax-efficient way to hold property in some cases, but the lease terms — including annual rent adjustments and lease duration — must be carefully reviewed before you commit, because the ground-rent escalations can surprise an unprepared buyer.
Udlejningsejendom (pure rental property)
If you hold a property purely as a rental (udlejningsejendom), you can deduct all expenses against rental income, including:
- Mortgage interest
- Maintenance and repairs
- Property management fees
- Insurance
- Ejendomsskyld
- Depreciation on building value (not land)
Net rental income = Gross rent − All deductible expenses
This net amount is what you declare and pay tax on at your marginal rate.
Depreciation strategy
Depreciating the building at 4% per year is a powerful tool. For a building valued at DKK 2,000,000, annual depreciation is DKK 80,000 — directly reducing taxable income by that amount each year. Because it is a non-cash expense, it improves your after-tax cash flow without touching your bank balance.
Holding property in an ApS (limited company)
For investors with multiple rental properties, holding them in an ApS (anpartsselskab, or limited company) can be tax-efficient. The corporate tax rate in Denmark is 22%, which is significantly lower than the marginal income tax rate of up to 52.5%.
Advantages of an ApS
- Lower tax rate (22% versus up to 52.5%)
- Retained profits can be reinvested without personal taxation
- Limited liability protects your personal assets
- Easier to transfer ownership or bring in investors
Disadvantages
- Setup and ongoing administration costs
- Must file separate corporate tax returns
- Dividends paid to you as a shareholder are subject to 27%/42% shareholder tax
- More complex accounting and bookkeeping requirements
- Loan guarantees and related-party transactions carry specific tax rules
When it makes sense
An ApS typically becomes worthwhile when you own multiple rental properties or when your total rental income pushes you into the higher marginal tax bracket. For a single property with modest income, the administrative burden can outweigh the tax savings. The tax on dividends at 27%/42% when you eventually take money out also means the company structure defers tax rather than eliminating it — a timing advantage, not a free lunch.
Tips for Danish property investors
- Keep all receipts for maintenance, repairs and improvements. They are essential for substantiating deductions and avoiding challenges from SKAT.
- Use building depreciation — it is one of the most underused deductions available to property investors.
- Track your indexation — ensure the acquisition cost is correctly adjusted for the retail price index when calculating capital gains.
- Consider an ApS if you plan to build a portfolio of multiple rental properties.
- Use a property management company — the fees are deductible, and professional management helps you stay compliant with Danish rental regulations.
- Separate personal and rental finances — keep a dedicated bank account for rental income and expenses to simplify bookkeeping.
- Review your mortgage — ensure you are maximising your rentefradrag by structuring loans efficiently.
- Declare everything — SKAT has access to rental contract data and will cross-reference. Non-declaration carries significant penalties.
Worked example
Suppose you own a rental apartment in Copenhagen:
| Item | Amount |
|---|---|
| Purchase price | DKK 3,000,000 |
| Annual rent received | DKK 180,000 |
| Mortgage interest | DKK 120,000 |
| Maintenance costs | DKK 30,000 |
| Property management fees | DKK 18,000 |
| Net rental income | DKK 12,000 |
At a marginal tax rate of approximately 52%, the tax on DKK 12,000 is DKK 6,240.
However, the mortgage interest also qualifies for rentefradrag, which provides an additional tax benefit. The rentefradrag reduces the effective cost of borrowing, making the overall return on the property more attractive than the net income figure alone suggests.
Total tax benefit
- Tax on net rental income: DKK 6,240
- Rentefradrag benefit: reduces your overall tax bill
- Depreciation (4% on building value, say DKK 2,000,000): DKK 80,000 deduction, saving approximately DKK 41,600 in tax at 52%
When you factor in depreciation, your effective tax position improves significantly — potentially resulting in a tax refund on the property even though it shows a small net income. That is the counter-intuitive reality of Danish property investing: a property can be genuinely cash-flow positive after tax while barely breaking even on paper, provided you use the available deductions properly.

Understanding Danish property tax rules is essential for making informed investment decisions. The combination of high marginal tax rates on rental income and relatively favourable capital gains treatment means careful planning — depreciation, expense tracking, keeping your main-residence years documented, and weighing an ApS structure — can make a significant difference to your net returns. The rules reward organisation rather than aggression, and investors who keep clean records tend to do well by them.
