Not one tax with two names: two taxes
They are confused constantly, and the confusion is expensive. Wealth tax is a state tax that has been ceded to the autonomous regions: each region fixes the exempt threshold, the tariff and the rebates, and keeps the revenue. The temporary solidarity tax on large fortunes is a state tax that has not been ceded: the state regulates it and collects it, and no region can rebate it.
Both are charged on the same thing — net wealth at 31 December — and for that reason the second was designed to sit on top of the first: the wealth tax actually paid is credited against the solidarity tax liability. That is the whole mechanism, and also the whole paradox.
The regional rebate is what activates the second tax
If you live in a region that does not rebate, you pay wealth tax, and when you reach the solidarity tax threshold you credit what you have paid: between the two you end up paying roughly what you were already paying. If you live in a region that rebates wealth tax at 100 %, your wealth tax liability is zero, and zero is what you have to credit. The solidarity tax is charged in full.
Put differently: above the state threshold the regional rebate saves you nothing, because the state collects exactly what the region gave up. That is the effect the rule was written to produce, and it has led some rebating regions to adjust their own legislation for precisely this reason. It is worth checking each year how your region stands, because this has moved in every direction.
The two columns
| Wealth tax | Solidarity tax on large fortunes | |
|---|---|---|
| Who sets the rules | The state, with broad regional powers | The state, with no regional powers |
| Exempt threshold | 700,000 € as a general rule, unless the region sets another | 700,000 € for a taxpayer with worldwide liability |
| Where a liability starts | Above the exempt threshold and the regional tariff | Above 3,000,000 € of taxable base |
| Main home | Exempt up to 300,000 € | Exempt up to 300,000 € |
| Regional rebates | Yes, and 100 % in some regions | They do not exist |
| Cross credit | Wealth tax actually paid is credited against the solidarity tax liability | |
| Form | 714 | 718 |
Who ends up paying which
- Moderate wealth in a region that does not rebate: pays wealth tax and never reaches the second.
- Moderate wealth in a rebating region: pays neither, but may still be obliged to file the first.
- Large wealth in a region that does not rebate: pays wealth tax and files the 718, where the credit leaves the liability at or near zero.
- Large wealth in a rebating region: pays no wealth tax and pays the 718 in full. This is the case the rule was written for.
- A non-resident with assets in Spain: is taxed on a limited basis, only on assets and rights situated here, and is within scope of both taxes. There is also a rule extending the charge to shares in non-resident entities whose assets consist mainly of property situated in Spain, aimed precisely at interposed corporate structures. Owning a Spanish villa through an offshore company does not take it out of scope.
This is the most common failure, and it happens almost always in rebating regions, for an understandable reason: someone who pays nothing assumes there is nothing to file. The obligation to file a wealth tax return arises in two situations, and either one is enough: that a liability results, or that the value of the assets and rights exceeds 2,000,000 €. That second threshold is measured on the value of the assets and rights even where they are exempt and even where debts would reduce them. In other words: you can have a nil liability, a 100 % rebate and a duty to file the 714. Not filing is a formal infringement, and it also leaves unrefreshed the information the system uses afterwards.
Neither tax is normally argued about on the rate: it is argued about on what each thing is worth. Real property goes in at the highest of three values, unlisted shares have their own rule, insurance policies and life or term annuities have theirs, and debts only subtract if they are deductible. Two returns over the same wealth, prepared on different criteria, can produce very different liabilities. Careful work belongs there, not in looking for shortcuts.
A single photograph, taken on 31 December
Both taxes work off a snapshot rather than a film. What matters is what you owned on 31 December, however the year went. Selling a property in November and holding the proceeds in cash on 31 December changes nothing about whether you file: it changes only which asset is being valued. Moving money between accounts in the last week of the year changes nothing at all.
That makes two facts worth getting right well before the year ends. The first is your region of residence on that date, because it sets the tariff and the rebate for the first tax. The second is whether any part of your wealth qualifies for an exemption that has to be in place by then rather than arranged afterwards. Neither is fixable in March, when the return is being prepared.
On the word «temporary»
The solidarity tax was announced as temporary, with an intended life of two tax years, and it has been rolled forward since. Planning over ten years on the assumption that it will disappear is as imprudent as treating it as permanent. The sensible course is to review each year both the rule in force and your region's legislation, because both have moved more than once.
When wealth tax or the solidarity tax on large fortunes fits neither column
The taxpayer whose income does not stretch to paying tax on what he owns. That is the situation the table does not cover, and it decides more bills than people expect: the retired owner with a substantial property holding and a modest pension, or the holder of shares in a family company that pays no dividend. For them there is the combined ceiling: the wealth tax charge plus the personal income tax charges cannot exceed 60 % of the personal income tax bases; where they do, the wealth tax charge is cut back, but never by more than 80 %, so at least a fifth of it always remains payable. The solidarity tax carries a limitation rule of its own built on the same idea.
The ceiling is one of the few legitimate levers left in this area, and for that reason it comes with counterweights: not every asset enters the calculation, and assets which by their nature cannot produce income are left out of it. This is technical ground with contested edges, so we put it plainly: it is studied case by case and documented, never assumed.
The second in-between case is the person who moves. Both taxes are photographs taken on 31 December: there is no apportionment by months, and someone who arrives in Spain in November is taxed on worldwide wealth for that same year if residence has been acquired. Within Spain, the competent region is not settled merely by where you spend New Year's Eve: there is a rule that looks back over earlier years, and it exists precisely because of moves of convenience towards regions that rebate the tax. Moving house in December to save the tax for that very year is among the manoeuvres that stand up worst to a review.
And a third, purely formal and expensive: marriage. Neither tax has a joint return. Each spouse files their own, and community property is attributed half to each. A couple with 1,500,000 € of community property have two estates of 750,000 €, each with its own exempt threshold and its own main home exemption, applied to that spouse's share. Putting everything into a single return is not only wrong, it costs money. Couples who married abroad should also know that which matrimonial property regime governs them is a prior question, and one we look at before splitting anything.
What to look at before deciding on wealth tax or the solidarity tax on large fortunes
The valued inventory is the work; everything else follows from it. To do it properly we need:
- Your region of residence and since when, with earlier years, both for the rule that fixes which region is competent and for the particular regional rules that will end up applying.
- For each property, three values: the rateable value, the acquisition value and the value checked by the authorities if there was one. It is declared at the highest of the three, and almost nobody has all three to hand.
- For unquoted shares, the accounts for recent years and whether or not they are audited, because the valuation rule changes accordingly.
- For insurance policies, the surrender value at 31 December, certified by the insurer; and for annuities, their actuarial present value.
- Debts, with the balance outstanding at 31 December and the purpose of each loan, because only those the law treats as deductible come off.
- Your personal income tax base for the same year, which is what allows the combined ceiling to be worked out before you pay more than you owe.
- The family business exemption conditions, one by one: shareholding percentage, management duties, remuneration for those duties and the weight of genuine business activity in the assets. It is the exemption that moves the most tax and the one most often lost over a documentary detail.
What we do with wealth tax or the solidarity tax on large fortunes
We build the valued inventory first, using the rules applicable to each class of asset rather than what each owner thinks something is worth. That tells us whether there is a duty to file, whether there is a liability, and under which of the two taxes. Then we look at the exemptions that may apply — the main home, and above all the family business and shareholdings exemption, which has demanding conditions and is lost easily — and at what it would take to satisfy them properly.
We do not promise the liability will come down: we undertake that what is declared will be properly valued and properly supported, which is what survives an enquiry. The line is on wealth tax and the form asks for the inventory by block.
