Speculation tax on property sales: the ten-year period

Article L-0083 · 01.10.2026 · 7 min. reading time · Joé Christian Ewrard

What does speculation tax mean in the context of real estate?

“Speculation tax” is a colloquial term. It refers to income tax on the profit from a private sale transaction. It may arise if a privately owned property is sold within the statutory ten-year period and no owner-occupation exemption applies.

The decisive factor is therefore not simply whether the selling price is higher than the previous purchase price. It must first be determined whether the sale falls under [Section 23 of the German Income Tax Act (EStG)](https://www.gesetze-im-internet.de/estg/__23.html) at all. Only then does the amount of any potential taxable profit become relevant.

The rule applies, among other things, to houses, owner-occupied apartments, undeveloped land and certain rights equivalent to real property. Buildings that are partly rented out or used for business purposes may need to be assessed separately. This is often relevant in the Eifel, for example in the case of former farmhouses with several residential units, attached commercial premises or separately used outbuildings.

The tax is not a fixed charge on the entire selling price. A taxable profit is generally included in the seller’s personal income tax assessment. The actual tax burden therefore depends on the individual circumstances. This calculation should be handled by a tax adviser.

How is the ten-year period calculated?

For a privately owned property, a sale is generally relevant for tax purposes if no more than ten years have elapsed between acquisition and disposal. Once this period has expired, profit from a private sale is generally no longer covered by this provision.

The binding purchase agreements are usually decisive for determining the relevant dates. In practice, the dates of the notarised agreements are therefore compared in particular. Payment of the purchase price, handover of the keys and entry in the land register may take place later without automatically determining the relevant date.

This leads to a common mistake: Owners count from the date of entry in the land register. Others use the date they moved in. Both can lead to an incorrect assessment. If the planned notary appointment is close to the end of the period, the calculation should be reviewed by a tax adviser before signing.

A building constructed at a later date does not automatically restart the entire period. However, the law includes buildings constructed, converted or extended within the relevant period in the assessment. Additional special rules apply to the division of land, separated building plots or a transfer from business assets. A simple calculation based on calendar years is not sufficient in these cases.

When does owner-occupation remove the tax liability?

The law provides for two options. Firstly, a sale may qualify for favourable tax treatment if the property was used exclusively as the owner’s residence between acquisition or completion and sale. This may also apply if the property was owned for only a short period.

The second option concerns properties that were initially rented out, for example, and later occupied by the owner. In that case, the property must have been continuously occupied by the owner in the year of sale and the two preceding calendar years. These do not have to be three full years. However, the continuous owner-occupation must cover the entire middle calendar year; shorter periods may be sufficient in the first and last calendar years. This interpretation has been confirmed by the [Federal Fiscal Court regarding owner-occupation over three calendar years](https://www.bundesfinanzhof.de/de/entscheidung/entscheidungen-online/detail/STRE202010060/).

Owner-occupation means that the owner actually lives in the property. Merely having a registered address there is not sufficient if the person clearly lives elsewhere in practice. Conversely, the property does not necessarily have to be the owner's sole primary residence. A second home occupied by the owner may also qualify under certain conditions.

Allowing a child to use the property free of charge may count as owner-occupation if the owner is entitled to child benefit or a child tax allowance for that child. This does not automatically apply to parents, siblings, adult children for whom there is no corresponding entitlement, or other relatives. Even allowing the owner's own mother or mother-in-law to use the property does not qualify as owner-occupation solely because of the close family relationship.

Vacancy is likewise not a reliable substitute. Periods of vacancy after moving out, temporary rental, or the use of only individual parts of the building are particularly critical. In such cases, every period should be documented precisely and assessed for tax purposes.

Who should calculate the potential profit before the sale?

Every owner whose purchase was less than ten years ago and whose owner-occupation cannot be clearly demonstrated should do the calculations. This applies in particular after periods of rental, where there is a home office with an independent business function, where the building contains several residential units, or where part of the property has been separated off.

The taxable gain is not simply the difference between two purchase prices. In particular, acquisition or construction costs and certain expenses directly related to the sale may be taken into account. If the property was previously rented out, depreciation claimed may affect the calculation.

Therefore, before deciding on a price, the original purchase agreement, invoices for construction work, rental documents, depreciation schedules, and anticipated selling costs should be compiled. An estate agent can assess the achievable market price and customary marketing costs. The binding tax assessment is carried out by a tax adviser.

This sequence protects against an unpleasant surprise. Anyone who plans solely on the basis of the expected sale proceeds may overestimate the amount actually available. This becomes particularly burdensome if the proceeds are intended to finance a new home, a payment within the family, or the repayment of a loan.

What applies to an inherited property?

For the ten-year period, an inheritance is generally not considered a new purchase. For tax purposes, the heir assumes the relevant acquisition made by the deceased. The decisive factor is therefore often when and under what circumstances the deceased acquired the property.

If the deceased acquired the house outside the ten-year period, a prompt sale by the heir may be treated differently for income tax purposes than the sale of a property acquired only recently. If the property was occupied by the deceased, it must also be examined whether and how this use benefits the heir. The rules on tax on disposal must be distinguished from a possible inheritance tax exemption for a family home.

In practice, documents are often missing after a death. Particularly for older houses in the Eifelkreis Bitburg-Prüm, Trier-Saarburg or the Vulkaneifel, purchase agreements, construction costs and subsequent extensions are not always fully documented. In that case, heirs should review the estate records, available tax documents and notarised deeds at an early stage.

With communities of heirs, there is an additional aspect to consider. If a settlement is first reached among the co-heirs and the property is sold later, the structure and sequence may be significant. An estate agent should provide a transparent overview of the interests involved, the condition of the property and a realistic range for the sale. The legal and tax arrangements should be clarified by a notary, lawyer and tax adviser.

What changes in the case of a gift?

Even a genuinely gratuitous gift does not generally restart the ten-year period. For the purpose of this assessment, the recipient assumes the donor's tax position. The relevant date may therefore be the donor's original acquisition date.

Caution is required if the recipient assumes loans, provides consideration, pays out siblings or grants rights to the donor. A transfer may then be wholly or partly for consideration. This may result in a different tax allocation than in the case of a gift made without consideration.

Gift tax and income tax on a subsequent sale are also two separate matters. A favourable valuation in one area does not automatically answer the question of capital gains tax on private property sales. The same applies to retained rights of residence or usufruct.

Before a transfer is made within a family or the property is sold shortly afterwards, the agreement, financing and intention to sell should be considered together. The notary structures and notarises the transfer. The tax adviser reviews the tax implications. If conflicts arise between the parties, it may also be advisable to consult a lawyer.

Why is separation particularly risky?

After a separation, one partner often moves out of the jointly owned house while the other partner remains there with the children. This is understandable on a personal level. For tax purposes, however, moving out may end the departing co-owner's owner-occupation of the property.

The Bundesfinanzhof has ruled that a spouse who has moved out does not continue to occupy their share themselves merely because their former partner and their child remain in the house. If the share is subsequently transferred or sold within the ten-year period, this may constitute a private sale transaction. Further details are provided in the [Bundesfinanzhof decision on a sale following separation](https://www.bundesfinanzhof.de/de/presse/pressemeldungen/detail/veraeusserung-eines-einfamilienhauses-nach-ehescheidung/).

A sale to a former spouse is also a sale for tax purposes. An agreement on the consequences of divorce, financial pressure or concern about a partition auction does not automatically remove the tax implications.

The tax implications should therefore be clarified before a co-ownership share is transferred, a sale date is agreed or a compensation payment is determined. At this stage, taxes are not the only consideration. Loans, the land register, maintenance, accrued gains and the children's living arrangements may be interconnected. The tax adviser, notary and, where appropriate, lawyer should therefore coordinate their work.

Which documents provide clarity before the sale?

The starting point is the original notarised purchase agreement and, in the case of an inheritance or gift, all transfer and estate documents. This should be supplemented by evidence of construction, extensions and major modernisation work, previous tax returns where the property was rented out, and evidence of when owner-occupation began and ended.

Registration records, utility bills and other documents that provide evidence of actual residential use are also helpful. They are no substitute for a tax review, but can help avoid uncertainty regarding periods dating back many years.

In the event of a separation, the move-out date, occupancy agreements and planned transfers of ownership should be documented. In the case of communities of heirs, an overview of ownership shares, compensation payments and previous agreements is also required.

For owners near the border with Luxembourg, both the German property and their personal tax situation may raise cross-border issues. The location of the property, place of residence, income and financing should then be reviewed together by a tax adviser with relevant experience.

First, gather the purchase agreement, proof of use and documents relating to inheritance, gifts or separation. Then have the potential sale price and the initial tax situation assessed separately before arranging a notary appointment or making plans for the proceeds. PRIOCASA can provide a market-based assessment of the property in the Eifelkreis Bitburg-Prüm, Trier and Trier-Saarburg, the Vulkaneifel and near the border with Luxembourg; binding tax and legal advice is provided by tax advisers, notaries or lawyers.

Frequently Asked Questions

Is the sale of a property always tax-free after ten years?

For a privately owned property, the gain is generally not subject to § 23 EStG once the ten-year period has expired. Exceptions include properties held as business assets, commercial property trading and certain transfer transactions. A tax adviser should review this distinction.

Do I have to live in the property myself for three full years?

No. For the second owner-occupancy option, a continuous period spanning the year of sale and the two preceding calendar years is generally sufficient. The middle calendar year must be covered in full.

Does the period restart in the event of an inheritance?

No, the date on which the deceased acquired the property is generally taken into account. Their original acquisition date is therefore important. Inheritance tax rules concerning the family home must be reviewed separately.

Does a gift count as a new purchase?

A purely gratuitous gift is generally not considered a new purchase for the ten-year period. The assessment may be more complex if debts are assumed, compensation payments are made or other consideration is provided.

After a separation, is it sufficient if my child continues to live in the house?

Not necessarily. If the former partner also continues to live there, case law does not automatically treat this as owner-occupation by the co-owner who has moved out. The specific circumstances should be reviewed before any transfer.
