Property taxes abroad - investor's guide

An investor buying abroad should understand where income is generated, where they are a tax resident, and what documents they need to collect so that portfolio optimization does not turn into a legal risk. Geographic diversification is part of wealth management today, but it does not exempt one from tax discipline. This applies to Spain, Oman, the UAE, Saudi Arabia, and Montenegro.

Rent, sale, and personal use of real estate create different fiscal effects. The investor should separate the country of income source from the country of their tax residency. They should also check whether they are acting privately, through a company, or via an SPV-type structure. A second-home apartment carries a different documentation burden. A unit in a rental pool or mixed-use development model carries another.

PlanoGroup analyzes these areas during the asset selection process. On the PlanoGroup blog, it is worth comparing the topic of taxes with an analysis of ROI, maintenance costs, and rental management. In practice, an investor's result depends on market mechanics rather than a slogan about low taxes. Service Charge, local fees, currency, ownership form, operator quality, and expense documents matter.

Where is the rent of a foreign property taxed?

Tax residency vs. the country where assets are located

The starting point is the Lex Rei Sitae rule. In practice, this means that income from real estate can be taxed in the country where it is located. This logic is described in Article 6 of the OECD Model Tax Convention. The Model does not replace the relevant DTC (Double Tax Convention), but it demonstrates the mechanism applied in many agreements.

A Polish investor must therefore separate two layers. The first is the law of the country where the apartment, villa, commercial unit, or land is located. The second is Polish rules for a person with tax residency in Poland. According to Polish PIT (Personal Income Tax) rules, a resident settles income from the country and from abroad in Poland, taking into account the relevant agreements.

This distinction is critical for premium real estate. An investor may pay local rental tax in Spain while simultaneously declaring income in Poland. In another case, local PIT may not occur, as is currently the case in UAE for ordinary individual income. However, the obligation for Polish analysis and archiving of evidence still remains.

The exemption with progression method works differently than the proportional credit method. With exemption, foreign income may affect the tax rate for income taxed in Poland. With proportional credit, foreign income is included in Poland, and the tax paid abroad reduces the Polish tax only up to a certain limit.

One must not choose the method intuitively. The investor should check the list of double taxation avoidance agreements and the text of the relevant agreement. They should also determine whether the country where the property is located has a DTC with Poland. For Oman, this point must be verified particularly carefully, as the lack of an agreement changes the analysis model.

The status of tax residency is often more complex than a registered address. The Polish tax authorities look at the center of personal and economic interests. Family, business management, location of assets, duration of stay, and sources of income all matter. For a portfolio spanning multiple jurisdictions, it is worth preparing a relationship map before purchasing.

A tax residency certificate has an evidentiary function. It can confirm residency for a foreign authority, bank, operator, or contractor. However, it does not resolve every dispute. If the factual situation is inconsistent, the document alone will not replace an analysis of the place of living and wealth management.

For the investor, the most important thing is to determine the source of income. Short-term rent, medium-term rent, rental pool, income from a hotel operator, and the sale of shares in a company may have different classifications. It is worth checking whether a payout from the operator is rent, a share of the result, a hotel service, or a profit distribution.

Step by step: how to determine the correct settlement method

Step 1: Establish the investor's tax residency based on their place of living, wealth management, and number of days of stay.

Step 2: Determine the country of income source. For real estate, this is usually the country where it is located.

Step 3: Download the text of the relevant DTC from the podatki.gov.pl portal. If there is no agreement, note this information.

Step 4: Check the method of avoiding double taxation. Compare exemption with progression and proportional credit.

Step 5: Ask your advisor about PIT-36 with the PIT/ZG attachment. Determine whether you submit the attachment for each country separately.

Step 6: Gather the residency certificate, local declarations, proof of tax payment, and operator reports. Without them, the net calculation is weak in terms of evidence.

Regional specifics: From Dubai to the Adriatic

Comparison of fiscal systems in key jurisdictions

The markets in which PlanoGroup operates do not form a single tax category. Spain is an EU market with an extensive IRNR (Non-Resident Income Tax) system for non-residents. Dubai and the broader UAE currently do not have a classic PIT for individuals, but they do have Corporate Tax for certain activities. Oman will introduce a PIT starting in 2028 for selected incomes above the threshold indicated in the law. Montenegro applies a flat tax on certain income categories. Saudi Arabia combines transactional taxes, land regulations, and ownership market reforms.

In Spain, a non-resident settles income from property located in Spain according to IRNR rules. AEAT on IRNR indicates that rental income from Spanish properties can be taxed in Spain. For EU and EEA residents, the rate is 19 percent, and for other taxpayers, 24 percent. EU and EEA residents can deduct costs directly related to the income if they meet the evidentiary conditions.

This is of great importance on the Costa del Sol. An apartment in the premium segment may have high occupancy, but the net result depends on tax, rental license, community fees, cleaning, insurance, and operator commissions. When analyzing offers such as St. Regis Residences Casares, the investor should check not only the purchase price. They must also ask about maintenance costs, rental rules, and local restrictions.

In the UAE, the picture is different. PwC Worldwide Tax Summaries points to the absence of federal and emirate PIT for individuals. At the same time, individuals running a business activity may fall within the scope of Corporate Tax if they meet threshold conditions. PwC also points out that remuneration, personal investment income, and income from real estate investments are not included in the business threshold if the appropriate conditions are met.

For Dubai, transactional and operating fees are of practical importance. The Dubai Land Department indicates a registration fee for property sales at 4 percent of the contract value. The Service Charge Index allows checking approved service charges. This is important because service charges can alter net yield more than the tax rate itself.

Oman for years was described as a jurisdiction without PIT for individuals. This shortcut requires updating. The Oman Tax Authority announced Royal Decree 56/2025, which introduces PIT starting in early 2028. The tax is to apply to individuals with annual income exceeding 42,000 OMR and amount to 5 percent of taxable income. An investor buying in 2026 should therefore model the scenario after the law changes.

In Oman, taxes are not the only filter. For ITC (Integrated Tourism Complex) projects, freehold, title deeds, escrow accounts, payment schedules, service charges, and rental rules matter. In the ROI analysis in Oman, PlanoGroup shows that the difference between gross yield and the net result may stem mainly from operator costs and vacancies. Therefore, real estate offers in Oman must be evaluated individually.

If the developer refers to the Greater Muscat Structure Plan (GMSP), the investor should check the road schedule, service phasing, permits, and the launch date of common areas. Capital Appreciation should be treated as a resale scenario, not a certainty.

Montenegro requires a separate calculation. According to PwC, rental income from real estate is taxed there at a rate of 15 percent. The tax base can take into account documented costs or standard costs. For tourist rentals, different levels of standard costs are available than for ordinary rentals. For projects such as Luštica Bay, the investor should check the unit's status, cadaster, local tax, and rental model.

Saudi Arabia is a market in the phase of regulatory opening to foreign capital. It is worth separating residential properties, tourism projects, land, and commercial units. The Saudi White Land Tax applies to white lands and vacant properties in certain situations. REGA also points to the importance of the real estate transfer tax. For the investor, this means the necessity of a local legal opinion before reservation.

Step by step: how to compare countries before buying

Step 1: Enter each country into a single table. Include PIT, rental tax, transactional tax, VAT, and service charges.

Step 2: Check official sources. For Spain, use AEAT, for Dubai, DLD, for Poland, podatki.gov.pl.

Step 3: Ask the developer for an annual fee table. Ask for an invoice example for a similar unit.

Step 4: Compare gross yield, net yield, NOI, occupancy, ADR, and operator costs. Do not mix rates from different rental models.

Step 5: Check the currency of income and the currency of costs. The Omani Rial is pegged to the USD, and Montenegro uses the euro.

Step 6: Assess regulatory risk. For Oman, include PIT from 2028, and for Saudi Arabia, new regulations on foreign ownership.

Evidentiary architecture: What documents to collect throughout the year?

Reporting costs and revenues in practice

Tax profitability does not happen when filing tax returns. It is built throughout the year as the investor collects documents. Without evidentiary architecture, net ROI becomes a declaration that cannot be defended. This applies especially to owners living in Poland who use an operator abroad.

The first set of documents concerns revenues. The investor should have a rental agreement, operator regulations, monthly reports, an annual revenue statement, and payout confirmations. In a rental pool model, one must know whether the report shows gross revenue, the result after costs, or the owner's share after deductions. These are not equivalent values.

The second set concerns fixed costs. These include service charges, community fees, property insurance, local fees, internet subscriptions, and management costs. Each invoice must have the correct data of the owner or company. When buying through an SPV, an error in the buyer's data can hinder settlement.

The third set concerns variable costs. These are utilities, cleaning, laundry, repairs, retrofitting, FF&E renewal, and air conditioning service. In Oman and the UAE, air conditioning is a significant operating cost. In Spain, the cost of utilities and cleaning can depend on seasonality and the tourist license.

The fourth set concerns transactions. The investor should keep the Reservation Form, SPA, transfer confirmations, title deed, escrow account statement, payment schedule, handover protocols, and KYC documents. When buying off-plan, it is also worth archiving communication about construction progress and schedule changes.

Proof of transfer is just as important as an invoice. The tax authority may ask whether the expense was actually incurred. For this reason, it is worth maintaining a separate account for investments or a separate record of cash flows. With multiple assets, a single card used both privately and for investments creates a weak evidentiary trail.

The problem begins when an investor calculates gross ROI. Suppose the operator shows yield before costs. After service charges, commission, utilities, insurance, local tax, and technical reserve, the result can drop by several percentage points. This is not a flaw of the investment. It is the normal difference between a marketing revenue rate and the owner's result.

This is precisely why PlanoGroup recommends asking for a sample owner statement during the purchasing process. The document shows what items the operator deducts before payout. For properties in Oman, one should ask about service charges, the furniture renewal fund, and owner usage rules. For properties in Spain, one must check cost invoices and the local rental license.

Step by step: how to build an investor tax folder

Step 1: Create a separate folder for each asset. Do not mix Spain, Oman, UAE, and Montenegro.

Step 2: Divide the folder into revenues, costs, taxes, bank, contracts, operator, and ownership documents.

Step 3: Save the operator's report every month. Ask for a breakdown into gross revenue, deductions, and net payout.

Step 4: Check the data on invoices. The buyer, property address, document number, and currency must be consistent.

Step 5: Archive transfer confirmations. For each invoice, keep proof of payment and the exchange rate.

Step 6: Compare the budget with the result once a quarter. Combine gross ROI, NOI, net yield, and cash-on-cash return.

Private ownership or Special Purpose Vehicle (SPV)?

Purchase structure vs. exit strategy and succession

The choice of purchase structure should be made before reserving the property. After signing the Reservation Form, changing the buyer may require the developer's consent, additional documents, and costs. When buying a completed unit, changing the buyer may also affect the bank, notary, and registry.

A private purchase is usually simpler. The investor shows a passport, proof of address, source of funds, tax documents, and account history. This model often suits a single second-home apartment intended to be used partly privately and partly rented. Simplicity, however, does not mean an absence of risks.

Private ownership ties the asset directly to the investor. A dispute with a tenant, operator, community, developer, or contractor concerns the owner. Therefore, even with a private purchase, contracts, insurance, clear management rules, and protocols are needed. The title deed alone is not enough.

An SPV (Special Purpose Vehicle) works differently. It can organize cash flows, separate operational risk, and facilitate the entry of partners. It can also help with a larger portfolio when an investor holds units in Oman, Dubai, and Southern Europe. However, it is not an automatic tax-reduction tool.

The cost of a company must be calculated like an investment cost. Licenses, accounting, audits, office costs, UBO reporting, a bank account, and legal services reduce the net result. For a single unit, these costs may be disproportionate. For multiple assets, they can provide order and a clear division of risk.

A Polish tax resident must additionally check CFC (Controlled Foreign Company) regulations. CFC forms show that the Polish system requires reporting income from controlled foreign entities in certain situations. This applies to both individuals and companies. Therefore, the decision regarding an SPV should be analyzed with a Polish advisor.

In GCC countries, the aspect of inheritance comes into play. Local probate procedures may differ from Polish family expectations. For assets in Dubai, Oman, or Saudi Arabia, it is worth checking the will, powers of attorney, share succession, and family access to documents. A company can facilitate share succession, but only with clearly described rules.

Equally important is the exit strategy. The sale of real estate, the sale of shares in a company, and the assignment of rights from an off-plan contract can have different consequences. The developer may restrict assignment before a certain payment level. The registry may require consent or new fees. The bank may demand AML documents with every significant change.

This topic is well elaborated in an article on when to choose buying through a company or privately. When comparing offers, it is also worth considering the specific asset type. Marriott Residences AIDA, Zen Residences in Muscat Bay, and Amazi Hawana Salalah may have different rental regulations, operator scopes, and owner usage rules.

Step by step: how to choose a purchase structure

Step 1: Define the goal. Separate second home, rental, flip, succession, wealth protection, and portfolio building.

Step 2: Ask the developer to confirm who can be the buyer. Check individuals, local companies, and foreign companies.

Step 3: Compare the cost of the structure. Include registration, licensing, accounting, audit, bank account, and UBO handling.

Step 4: Check CFC in Poland. Assess shareholding, control, level of taxation, and type of company income.

Step 5: Ask the bank about KYC and AML. Prepare the source of funds, source of wealth, resolutions, and account history.

Step 6: Outline the exit from the investment. Check unit sales, assignment, share sales, and tax consequences.

Operational hygiene: How to separate private stay and rental?

Proportional cost accounting in second home properties

A second home is a hybrid asset. Part of the year it serves the family, and part of the year it works in rentals. For the investor, this means convenience, but also the obligation to precisely separate costs. The tax authority may ask which expenses served to generate income and which served the owner's private stay.

The greatest risk arises with fixed costs. Service charges, insurance, internet, and some local fees occur even when the unit stands empty. They cannot be automatically assigned entirely to rentals. One must adopt a proportional methodology and apply it consistently.

Most commonly, the proportion of rental days to commercial availability days is analyzed. If the apartment was blocked by the owner for a private stay, those days should be excluded from the calculation. If the unit was available for rent but did not find a tenant, the vacancy can be an operating cost. The difference is tax-significant.

The reservation calendar becomes an evidentiary document. It should show rental days, owner stay days, service periods, technical blockades, and vacancies. The operator should be able to generate an annual report. The owner should have access to source data, not just a summary.

Variable costs require a separate approach. Guest cleaning, laundry, platform commissions, and check-in fees are related to rentals. Private purchases, owner flights, meals, and family expenses are not property costs. The boundary should be described before the first season.

In condohotel projects, the rules are sometimes included in the owner's regulations. The owner may have a specified number of stay days. One must check whether these days can be used in the high season or upon prior reservation. One must also know whether the stay reduces the share in the rental pool.

In medium-term rentals in Oman, a different cost profile matters. Fewer rotations reduce cleaning costs, but the importance of utilities, internet, and air conditioning service increases. A good solution can be a utility limit in the contract, known as a utility cap. The surplus is then settled according to meters.

In Spain, there is the tourist license and local rental rules. Some municipalities restrict short-term rentals. Others require registration or guest reporting. For a tax investor, it is important that the operational model complies with local law. Without this, the cost may be difficult to defend.

Step by step: how to separate private and commercial use

Step 1: Download the reservation calendar from the operator. It must cover the entire year, not just successful bookings.

Step 2: Mark rental days, owner days, vacancies, service, and technical blockades. Each category has a different meaning.

Step 3: Divide costs into fixed and variable. Analyze service charges differently than post-guest cleaning.

Step 4: Determine the cost proportion. Compare rental days with commercial availability days and private days.

Step 5: Ask the operator for a sample owner statement. Check whether the document shows owner stays and deductions.

Step 6: Archive evidence. Keep the calendar, invoices, reports, payment confirmations, and contracts with the operator.

Preparation for a professional consultation

Briefing for a tax and financial advisor

A good tax consultation begins before the meeting. The advisor should not analyze a general idea, but a specific cash flow model. The investor should prepare a Cash Flow Projection, purchase structure, country, currency, payment schedule, anticipated rental model, and developer documents.

The first block of questions concerns residency. Does the investor remain a Polish tax resident? Do they have family or economic ties in other countries? Do they plan to change their place of stay? Do they need a residency certificate? These questions affect every subsequent element.

The second block concerns income. The advisor should know whether the unit will be rented short-term, medium-term, annually, through an operator, or in a rental pool model. Rent from a tenant is analyzed differently. A share in a hotel property's result is analyzed differently. Selling the right from an off-plan contract is analyzed differently.

The third block concerns costs. The investor should provide service charges, operator commission, utility costs, insurance, registration fees, legal costs, VAT, transactional tax, furnishing costs, and technical reserves. The lack of this data turns the conversation into a general evaluation.

The fourth block concerns structure. The advisor should compare individuals, Polish companies, local companies, SPVs, and holdings. They should also check CFC, withholding taxes, share reporting, dividend flows, and the source of funds. In private banking, these elements are part of a real process.

The fifth block concerns reporting. A Polish investor may have obligations to the Polish tax office, local authority, bank, or statistical institutions. Reporting to the National Bank of Poland (NBP) depends on asset values, cash flows, and entity status. This point must be checked before the first transfer, not after a year.

The sixth block concerns legal risk. When buying off-plan, one should check the escrow account, schedule, delay penalties, finishing standard, handover procedure, and assignment possibilities. For a completed property, one must check the title deed, encumbrances, community, rentals, insurance, and technical condition.

PlanoGroup can coordinate the investor's conversation with a local lawyer, tax advisor, and operator. In practice, it is worth matching data with the offer rather than analyzing the market in isolation from a specific unit. For Oman, these can be Marriott Residences AIDA, Zen Residences in Muscat Bay, or Amazi Hawana Salalah. For Montenegro, an example is Luštica Bay.

For Saudi Arabia, it is worth reading the purchase process in Saudi Arabia and checking current REGA acts. For Montenegro, the guide on what the property purchase process looks like in Montenegro is helpful. Both markets have a different logic of registration, financing, and local costs.

Step by step: how to prepare a briefing for an advisor

Step 1: Prepare a description of the investor. Provide tax residency, capital source, purchase goal, and asset holding horizon.

Step 2: Prepare the property card. Add price, area, country, currency, market type, freehold, or ITC status.

Step 3: Attach the Cash Flow Projection. Show revenues, costs, taxes, service charges, operator, and three occupancy scenarios.

Step 4: Gather developer documents. Ask for the SPA, Reservation Form, escrow, schedule, permits, and assignment rules.

Step 5: Ask questions about CFC, PIT/ZG, NBP, DTC, VAT, local tax, and residency certificate.

Step 6: Request conclusions in writing. Oral opinion is not sufficient for an international portfolio.

Investment consultation with PlanoGroup

If you plan to diversify your portfolio through real estate in Oman, Dubai, Spain, Saudi Arabia, or Montenegro, start with data. In the first conversation, it is worth discussing the purchase goal, ownership structure, anticipated rentals, tax risk, and post-handover management method.

PlanoGroup works on specific investment parameters. The analysis covers location, developer documents, rental model, maintenance costs, anticipated net ROI, and sales options. When buying abroad, what matters is not the number of viewed offers, but the quality of rejected risks.

The next step should be a consultation with the appropriate tax advisor and local lawyer. The team's role is to connect the investor with individuals who know the practice of a given market. Thanks to this, the conversation about taxes takes place before the reservation transfer, rather than after signing the contract.

FAQ

Do I need to report rental income from abroad in Poland?

If the investor is a Polish tax resident, they should analyze the obligation to declare foreign income in Poland. The rules depend on the country where the property is located, the relevant DTC, and the method of avoiding double taxation. In practice, data on revenue, costs, and locally paid tax is needed.

One should not assume that the lack of local PIT closes the matter in Poland. Income from Oman, the UAE, or another jurisdiction may still require Polish qualification. In many cases, PIT-36, PIT/ZG, exchange rates, and operator documents are analyzed. The final qualification should be confirmed by a tax advisor.

What documents are needed to settle rental income?

The basis consists of rental agreements, operator reports, cost invoices, payment confirmations, service charge documents, insurance, utilities, and local tax declarations. In a rental pool model, a document showing the revenue distribution method is needed. When renting through an operator, a management agreement is required.

It is worth collecting documents on a monthly basis. After a year, it is difficult to reconstruct whether a given payment concerned post-rental repairs, a private stay, or furnishings. A well-described tax folder shortens the advisor's work and reduces the risk of errors in net ROI.

Does a private stay affect cost settlement?

Yes, because owner stays change the way costs are assigned. Private days should not be treated as property working days. Fixed costs may require proportions, and variable costs must be assigned to the real purpose of the expense.

Does buying through a company simplify taxes?

Not always. A company can help with multiple assets, partners, financing, succession, and separating operational risk. It can also increase costs and reporting obligations. The mere registration of an SPV does not solve tax problems.

What most frequently ruins tax calculations?

The most common mistake is counting gross yield as the investor's result. The second mistake is the lack of invoices and payment confirmations. The third is mixing private costs with rental costs. The fourth is omitting local fees that are not named taxes, but lower the net result.

Can rental costs be deducted in Spain?

EU and EEA residents can deduct certain costs directly related to income from Spanish real estate if they meet evidentiary conditions. AEAT indicates that other taxpayer groups generally settle income without cost deductions. IRNR rates differ between EU/EEA residents and other taxpayers.

In practice, an owner from Poland should gather invoices, proofs of payment, and documents linking the cost to the rental. This applies to management, utilities, repairs, insurance, and community fees. Without proof, the cost may not work in the settlement.
