Advertised yield vs the yield in your pocket: what taxes really change

You spot a listing advertising a 6% yield. The number is attractive, it justifies the purchase, it reassures you. But between that glossy percentage and the money that actually lands in your account each month, there is a gap that no one takes the time to show you. The net rental property yield after tax, the one that truly matters, can end up half the figure advertised. This article follows a single rent payment euro by euro, from the advertised gross to the net actually pocketed, so you know exactly what you are signing.

Why the advertised yield almost always lies

Gross yield is the star figure of property listings. It is calculated in one line: annual rent divided by purchase price, multiplied by one hundred. A property bought for 200,000 euros that generates 12,000 euros in annual rent therefore advertises 6%. Clean, reassuring, easy to sell.

The problem is that this figure ignores everything that happens after the rent comes in. It accounts for neither charges, nor rental voids, nor property tax, nor income tax, nor social levies. It represents the best-case scenario, the one where an ideal tenant pays all year round without ever interrupting the cash flow and where the taxman takes nothing.

That scenario does not exist. In real life, an advertised gross yield of around 8% can fall back towards 7.2% net once you subtract 8% in management fees, roughly 5% in annual rental voids, and property tax. And this first cut happens before we even mention taxation.

The cities advertising the highest gross yields in 2026, such as Mulhouse, Saint-Étienne, Le Mans, or Limoges, often sit between 7% and 11%. At the opposite end, Paris, Lyon, and Bordeaux offer low gross yields and bet on capital appreciation rather than cash flow. An investor comparing two cities on gross yield alone is therefore reasoning the wrong way.

Since interest rates began climbing in mid-2022, achieving a genuinely attractive return has become harder. The net-after-tax calculation is no longer an accountant's refinement, it is the central decision-making tool. A high advertised yield that overlooks charges, voids, and tax remains a mirage. Learning to read a yield before signing means learning to ignore the shop-window figure and rebuild the one that counts. If you want the full methodology, our guide on how to calculate the return on a rental property investment walks through each step.

The starting point: gross rent of 12,000 euros a year

Let us take a concrete case and follow it all the way through. You buy a flat in a mid-sized city with an attractive yield. The property generates 12,000 euros in annual rent, or 1,000 euros a month. The purchase price, fees included, comes to 200,000 euros. The advertised gross yield is therefore 6%.

This is the figure that will appear in the listing, in the seller's projection, in the agent's pitch. It sets the psychological anchor. You start from 6%, and everything that follows will nibble away at that starting point.

These 12,000 euros represent the absolute gross, the headline rent. They assume the property is let twelve months out of twelve, without a single gap between tenants, without a single unpaid month, without a single month of works. They also assume you pay nothing to manage the property, which is false, whether you manage it yourself or through an agency.

Gross rent is a theoretical figure, useful for comparing properties against one another, but dangerous if you mistake it for disposable income. No one lives on gross rent. You live, possibly, on what remains after every deduction. And these deductions come in several successive waves, each eating a little more into the initial figure.

The first wave concerns the charges that come off before tax. The second wave is income tax, calculated according to your marginal rate. The third wave is social levies at 17.2%. By the end of this journey, the initial 12,000 euros will have shrunk. Let us see by how much.

What the seller shows you, what they forget to mention

The seller shows you the rent and the price. They calculate the gross figure in front of you and stop there. This is not dishonest, it is simply partial. Their job is to sell the property, not to anticipate your tax return.

What they forget to mention is that property tax can represent one to two months of rent every year. That if you hand management to an agency, you should count on roughly 8% of rent in fees. That a property is rarely occupied 100% of the time, with an average void of 5% being realistic. And above all, that the taxman expects their share of net rents, a share that depends directly on your personal tax situation.

Two identical buyers facing the same property can end up with radically different net returns. A lightly taxed taxpayer will keep far more than one in a high bracket. Net yield is therefore never a characteristic of the property alone. It is the product of an encounter between a property and your tax profile.

First cut: the charges that come off before tax

Before the taxman enters the scene, a series of expenses already reduces the gross rent. These charges are unavoidable and recur every year. Ignoring them means overestimating your yield from the very first line.

Property tax comes first. Depending on the local authority, it often represents the equivalent of one to two months of rent. On our 12,000 euros, let us assume a prudent 1,000 euros a year, or one month of rent. Understanding who pays what between landlord and tenant helps you avoid nasty surprises here.

Next come management fees. If you delegate to an agency, count on roughly 8% of rent collected, or nearly 960 euros a year. Even managing it yourself, your time has a value and some ancillary costs remain, such as non-occupying owner insurance or accounting.

Rental voids are the third deduction, often underestimated. Between two tenants, weeks pass in searching, inventory checks, and sometimes refurbishment works. An average void of 5% cuts 600 euros from the rent over the year.

Finally, non-recoverable charges and routine maintenance add up: repairs, the share of building charges that cannot be passed on to the tenant, minor works. Let us count 500 euros to stay realistic.

Add up these cuts. Property tax at 1,000 euros, management at 960 euros, voids at 600 euros, maintenance at 500 euros. The total exceeds 3,000 euros. Our 12,000 euros of gross rent already falls to around 8,940 euros of income net of charges, before any tax.

The yield, meanwhile, drops mechanically. From 6% gross, we already fall below 4.5% once charges are subtracted. And we have not yet seen the taxman go by. This first cut explains why an investor who reasons in gross terms alone is setting themselves up for disappointment at their first tax return.

Income tax, the guest who takes the biggest share

Once charges are deducted, the taxman calculates their share of net rental income. Two tax regimes coexist for unfurnished lettings, and the choice between them changes everything.

The micro-foncier regime applies a flat 30% allowance on gross rents. It is reserved for unfurnished lettings and capped at 15,000 euros of annual rental income. On our 12,000 euros of rent, the allowance brings the taxable base down to 8,400 euros. Simple, automatic, no receipts required. But the 30% allowance replaces your actual charges. If your charges exceed 30% of rents, this regime makes you pay more than necessary.

The régime réel, by contrast, lets you deduct the charges actually incurred: property tax, management fees, loan interest, works, insurance. It becomes worthwhile as soon as your actual charges exceed 30% of rents. In our example, with more than 3,000 euros of charges on 12,000 euros of rent, or 25%, the micro-foncier remains broadly competitive, but the gap narrows.

Let us stay with the micro-foncier for the clarity of the calculation. The taxable base is 8,400 euros. This sum is added to your other income and taxed according to your marginal tax rate. This is where two identical investors facing the same property diverge radically.

A non-taxable person will pay nothing on this base. Someone in the 30% bracket will pay roughly 2,520 euros of income tax on these rents. Someone at 41% will pay even more. The same property, the same rent, but a tax bill that varies from nothing to several thousand euros depending on your tax return.

This is precisely why a net yield can never be read from a listing. It is calculated in the light of your own situation. The rent is a feature of the property, the tax is a feature of your profile.

Marginal rate: the figure that decides everything

Your marginal tax rate is the single most decisive figure in this entire calculation. The 2026 scale, applied to 2025 income, provides for a first band at 0% up to 11,294 euros per share, then 11% from 11,295 to 28,797 euros, then 30%, 41%, and 45% for the higher bands.

The marginal rate is the rate applied to the top slice of your income, and therefore to your additional rental income. If you are at 30%, every euro of taxable rent costs you 30 cents in income tax, to which social levies are then added.

In practice, an investor at an 11% marginal rate keeps a far larger share of their rent than one at 41%. Before any rental purchase, knowing your marginal rate is not optional, it is the absolute prerequisite. It determines whether the project is profitable or whether unfurnished rental property becomes a tax burden you will need to offset through other arrangements.

Social levies, the deduction people forget to count

After income tax, a third wave hits the same rental income: social levies. Their overall rate stands at 17.2%, a historically stable level. They comprise the CSG at 9.2%, the CRDS at 0.5%, and the solidarity levy at 7.5%.

Beware of a common confusion. Some sources mentioned in 2026 a possible rise in the CSG that would bring the overall rate to 18.6%. This change was not consistently confirmed at the time of writing, and the stable reference rate remains 17.2%. Always check the rate in force on official sites before finalising your calculation.

These 17.2% apply to net rental income, that is, to the taxable base after the allowance or deduction of charges. On our micro-foncier base of 8,400 euros, social levies therefore represent roughly 1,445 euros.

One point too often overlooked deserves your attention: part of the CSG is deductible. Out of the 17.2%, a CSG share of 6.8% can be deducted from your taxable income for the following year, to be carried over in your return. The remaining 2.4% of CSG, the CRDS, and the solidarity levy are not deductible. This partial deductibility slightly eases the real burden over time, but it does not radically change the equation.

The trap with social levies is their invisibility in quick projections. Many investors calculate their income tax and simply forget these 17.2%. Yet they apply regardless of your income level, even to someone not liable for income tax. A household at a 0% marginal rate will still pay 1,445 euros of social levies on this base.

Added to income tax, these levies complete the transformation of the yield. For our taxpayer at a 30% marginal rate, the total tax bill approaches 3,965 euros a year between income tax and social levies. It is this sum, added to the charges already deducted, that widens the gap between the advertised figure and the real one.

The rent that actually lands in your account

Let us retrace the full journey of our 12,000 euros. Starting point, gross rent of 12,000 euros for an advertised yield of 6% on a property worth 200,000 euros.

First cut, the charges. Property tax, management, voids, and maintenance remove more than 3,000 euros. That leaves around 8,940 euros of income net of charges.

Second cut, income tax. Under the micro-foncier, the taxable base of 8,400 euros generates roughly 2,520 euros of tax for someone at a 30% marginal rate.

Third cut, social levies at 17.2% on that same base, or roughly 1,445 euros.

Let us tally up. From gross rent of 12,000 euros, remove the actual charges, then income tax, then social levies. In our 30% marginal rate scenario, only around 4,500 euros are actually available in your account at the end of the year. The net yield after tax then falls to somewhere between 2.2% and 3.2% depending on the precise assumptions on charges and deductibility.

This illustration remains an educational example built from verified rates. Your actual situation will depend on your marginal rate, your tax regime, and the real charges of your property. But the order of magnitude is beyond dispute: the net yield after tax is often half, or less, of the advertised gross yield.

It is precisely this gap that should guide any investment decision. Comparing two properties on their gross yield makes no sense until you have rebuilt each one's net-after-tax figure, with your own tax profile as the variable.

From 6% advertised to 3.2% real: the full calculation

Let us sum up the trajectory in one clear sequence. The 6% advertised corresponds to 12,000 euros divided by 200,000 euros, with no deduction whatsoever.

Once charges are removed, roughly 3,060 euros, income net of charges falls to 8,940 euros, bringing the yield to around 4.5%.

Income tax of 2,520 euros at a 30% marginal rate lowers the figure further, below 3.5%.

The 1,445 euros of social levies finish the job. The rent actually available stands at around 4,500 euros, a net yield after tax close to 2.2% to 3.2% depending on how refined the calculation is.

The message is clear: a property sold at 6% actually returns, for a moderately taxed person, barely more than 3%. Mentally halving any advertised gross yield is a healthy survival reflex for any property investor.

Three levers to bring net closer to gross

Reducing the gap between gross and net is possible. Three levers come up systematically among savvy investors.

First lever, the choice of tax regime. The micro-foncier and its 30% allowance suit you when your actual charges stay below 30% of rents. As soon as your charges exceed that threshold, notably where loan interest is high or works are involved, the régime réel becomes more advantageous because it lets you deduct the full amount of actual charges. Simulating both regimes before choosing is not an option, it is a necessity, and the right choice can represent several hundred euros of difference each year.

Second lever, the property loss carry-forward. When your deductible charges exceed your rents, notably in a year of major works, you generate a property loss. This loss cancels the social levies for the year, and its surplus can be carried forward for ten years against your future rental income. It is a powerful mechanism for smoothing taxation over time, particularly suited to properties needing renovation.

Third lever, furnished letting under the non-professional furnished landlord regime at the actual scheme. By opting for the industrial and commercial profits regime with depreciation, you deduct the accounting wear and tear of the property and furnishings. This depreciation sharply reduces, sometimes to zero, the taxable result. With the 17.2% social levies then applying to a result already reduced by depreciation, the total deduction falls significantly. This arrangement explains the success of furnished letting among investors seeking to preserve their net yield.

These three levers do not eliminate taxation, they optimise it within the legal framework. In return, they call for a little technical skill, often the support of an adviser or an accountant. The cost of this support is quickly recouped given the sums at stake. Add to this growing constraints to anticipate, such as the energy performance certificate and rent caps in certain cities, which weigh on the ability to let and therefore on the real yield.

Conclusion: knowing how to read a yield before you sign

Gross yield is a shop-window figure. It serves to compare, to entice, to anchor a decision. But it says nothing about what you will actually receive. Between the 6% advertised and the 3% actually pocketed lie the charges, the income tax calculated according to your marginal rate, and the social levies at 17.2%. Three successive waves that almost halve the starting figure.

The lesson is simple. Never sign on a gross yield. Always rebuild the net rental property yield after tax based on your own situation, then pull the optimisation levers that suit you. It is the only figure that deserves your attention.
