Property tax is the one cost of second-home ownership that never takes a holiday. It arrives every year, it rises with local valuations, and it catches many buyers off guard — especially those purchasing abroad for the first time. According to Bankrate’s 2025 study, the hidden costs of home ownership (taxes, insurance, maintenance and utilities combined) now average $21,400 per year across the United States alone. In popular European destinations the picture is different but no less complex, with rates, surcharges and local levies varying wildly from one municipality to the next.
For co-ownership property buyers, the arithmetic changes dramatically. Because you hold a fractional share — typically one-eighth — you pay only your proportional slice of every bill, including property tax. That single structural advantage can turn a prohibitively expensive second home into a genuinely affordable lifestyle choice. This guide breaks down exactly what co-owners pay in every major market, how the 2026 SALT deduction overhaul reshapes the US picture, and why fractional ownership is fast becoming the smartest route to luxury holiday-home ownership.
The Basics
How Property Tax Works When You Co-Own a Home
In a typical co-ownership arrangement, a registered LLC (Limited Liability Company) or equivalent legal entity holds the property title. Each co-owner is a shareholder in that entity, owning a deeded real-estate interest — not a timeshare, not a points scheme, but an actual stake in bricks and mortar that appreciates with the market. The LLC receives the annual property-tax bill and splits it proportionally among shareholders.
If the annual property tax on a luxury chalet in Colorado is $24,000, an owner of a one-eighth share pays just $3,000. That share is still tax-deductible under the same rules that apply to any homeowner, and it still counts toward the SALT cap on your federal return. The only difference is scale — and that difference is what makes co-ownership explained such a compelling proposition for buyers who want access to premium destinations without the premium overhead.
Management companies handle the entire administrative chain: they receive the bill, divide it, invoice each co-owner, and file all necessary documentation. As a co-owner you never need to chase a local tax office or navigate a foreign-language assessment notice. It is one of the many reasons the running costs of a fractional ownership property tend to surprise people — they are far lower and far simpler than expected.
The most powerful argument for co-ownership vs full ownership is not philosophical — it is mathematical. Consider a luxury property worth €1 million in the south of France. A sole owner faces an annual taxe foncière of around €8,000, plus a taxe d’habitation surcharge of approximately €3,500, bringing the total property-tax bill to roughly €11,500 per year. Add insurance (€2,000), maintenance (€5,000–€10,000), and management (€4,000–€6,000), and the hidden annual overhead easily exceeds €25,000.
A one-eighth co-owner of the same property pays approximately €1,437 in property tax and around €3,125 in total annual running costs. The property is professionally managed, maintained to a luxury standard, and available for around 45 days per year — which, for most second-home owners, is more time than they would actually spend there anyway. Research from the National Association of Realtors shows that the average US second-home owner uses their property for just 17 days per year, meaning sole owners often pay full-year taxes for barely two-and-a-half weeks of enjoyment.
For buyers considering the switch, benefits of fractional ownership for second homes explains why the financial case has never been stronger.

|---|---|---|---|
| USA (Colorado) | Property Tax | 0.51 % | $637 / year |
| France | Taxe Foncière + Surcharge | 0.5 %–1.5 % | €1,437 / year |
| Spain | IBI | 0.3 %–0.7 % | €312–€875 / year |
| Italy | IMU | 0.86 %–1.06 % | €1,075–€1,325 / year |
| Portugal | IMI | 0.3 %–0.8 % | €375–€1,000 / year |
| Croatia | None (most types) | 0 % | €0 / year |
Smart Structuring
How the LLC Structure Optimises Your Tax Position
Every co-ownership property is held inside a purpose-built legal entity — typically an LLC in the US or an SCI (Société Civile Immobilière) in France. These structures are not tax-avoidance vehicles; they are tax-optimisation vehicles designed by specialist property-law firms to ensure each co-owner receives the most favourable treatment available under local legislation.
In the United States, the LLC is treated as a pass-through entity for federal tax purposes. Each co-owner reports their share of income and deductions on their individual return, which means you retain full access to mortgage-interest deductions (up to $750,000 of qualifying acquisition debt across all your homes) and property-tax deductions within the SALT cap. There are no additional corporate filings, no double taxation, and no partnership formalities to manage.
In France, the SCI achieves a similar result by allowing each co-owner to deduct their share of property taxes, mortgage interest, and maintenance costs against any rental income generated by the property. The management company files the SCI’s annual return and distributes individual tax statements to each shareholder. The entire process is hands-off — exactly the kind of hassle-free ownership that draws buyers to co-ownership buying process in the first place.
Even with professional management, co-owners benefit from understanding the tax terrain. Mistake one: assuming foreign property taxes are deductible in the US. Since 2018, the TCJA has prohibited deductions for foreign real-property taxes, and the 2026 legislation continued that prohibition. If you co-own in Europe and file US taxes, your IBI or taxe foncière does not reduce your federal bill — though it may still be deductible in your state of residence.
Mistake two: ignoring the SALT phase-out. The new $40,400 cap is generous, but if your modified AGI exceeds $505,000 it begins to shrink. High-earning co-owners should model the phase-out with their accountant before assuming the full deduction. Mistake three: forgetting non-resident surcharges. Several French and Spanish municipalities impose additional levies on properties classified as secondary residences. These are built into your co-ownership cost structure, but it pays to know they exist.
Mistake four: conflating property tax with capital gains tax. They are entirely separate obligations — for a deep dive on the latter, see our guide to capital gains tax. Mistake five: not claiming rental-income offsets. If your co-owned property generates rental income through managed holiday lets, your share of property tax can often be offset against that income, reducing your net tax liability further. Speak with a tax adviser to ensure you are capturing every available benefit.
Future Outlook
What Is Changing in 2027 and Beyond?
Tax policy never stands still, and co-owners should keep one eye on the horizon. In the US, the SALT cap is set to rise by 1 % annually through 2029, reaching approximately $42,000 by 2029 before reverting to $10,000 in 2030 unless Congress intervenes. That sunset provision makes the next few years a particularly attractive window for American buyers to lock in co-ownership positions while deductions remain generous.
In Europe, Spain is reviewing its cadastral valuations in several regions, which could push IBI bills higher for luxury properties. France continues to phase out the taxe d’habitation for primary residences, but secondary-residence surcharges are rising in Paris and other major cities. Italy has signalled potential IMU adjustments for high-value properties in tourist-heavy municipalities around Lake Como and the Amalfi Coast.
The constant across all these markets is that co-ownership insulates buyers from the worst of any increase. A 20 % rise in property tax is painful when you own 100 % of a home; it is barely noticeable when you own one-eighth. That built-in resilience is why best fractional ownership properties continue to attract buyers who value both lifestyle and financial prudence.
Common Questions
Frequently Asked Questions
Do I pay property tax on a co-ownership property?
Yes — but only your proportional share. If you own one-eighth of a property, you pay one-eighth of the annual property-tax bill. The management company handles all invoicing and filings on your behalf.
Can I deduct co-ownership property taxes on my US federal return?
Yes, if the property is in the United States and you itemise deductions. Your share of property tax counts toward the SALT deduction, which is capped at $40,400 for the 2026 tax year. Foreign property taxes are not deductible on US federal returns.
How do property taxes work on co-owned European homes?
The legal entity holding the property (such as an SCI in France or an SL in Spain) receives the tax bill and divides it among co-owners. Each owner pays their share, and the management company handles all local compliance and paperwork.
Is co-ownership more tax-efficient than owning a second home outright?
In most cases, yes. You retain the same per-share deductions available to sole owners, but your total tax exposure is a fraction of the whole-property bill. You also avoid the common problem of paying full-year taxes on a home you use for only a few weeks.
What happens if property-tax rates increase in my co-ownership destination?
Any increase is shared proportionally among all co-owners. A 20 % rise in tax that would cost a sole owner an extra €2,000 costs a one-eighth co-owner just €250. The management company notifies you of any changes and adjusts your quarterly invoices accordingly.
Are there any countries where co-owners pay no property tax?
Croatia currently has no annual property tax on most residential property types, and several other countries (such as Malta and Monaco) have very low or zero recurring property levies. Your co-ownership advisor can help you identify the most tax-efficient destinations for your situation.
