Local business tax and its cap

A business turning over 400 000 € but generating only 20 000 € of value added can pay more local tax than its activity actually produces. The cap exists to correct that, and it has to be claimed: it never applies of its own accord.

Two charges, one tax

The local business tax is not a single tax at all but the sum of two separate charges. The first rests on the rental value of the premises the business actually uses; the second on the value added that its activity produces.

These two bases bear no relation to one another. A well-equipped workshop in a high-rate municipality carries a heavy property charge, whether its value added is thriving or close to nothing that year.

The value added charge, for its part, does not concern every business. Below a turnover threshold it is simply not due, so that the tax then reduces to its property component alone.

That asymmetry is precisely what makes the cap useful to small structures. They often pay only one of the two charges, but that one takes no account at all of what their activity has actually produced.

The imbalance corrected is therefore structural. A tax resting on premises does not follow activity; a difficult year mechanically increases the relative weight of the property charge, although nothing in its computation has changed.

The rate and the reference period

Relief opens where the total of the two charges exceeds a fraction of value added. That rate is not fixed over time: it moves from one year to the next, and checking the rate for the year concerned is the first step of the calculation.

The value added retained is the one determined under the rules applying to the charge based upon it. It is neither the value added of a management report nor a direct accounting figure: it follows closed lists of income and expenses.

That value added is itself capped as a percentage of turnover, at two different levels according to the size of the business. This second ceiling protects activities whose value added is very high relative to the receipts they record.

The period used and the businesses concerned

The reference period is the tax year itself where the financial year matches the calendar year. Otherwise it is the last twelve-month financial year ended during that year which provides the base for computing value added.

• An activity with low value added but costly production equipment
• A business whose premises sit in a high-rate municipality
• A loss-making year, or one of sharply reduced activity
• A structure paying the minimum charge on modest turnover

These profiles all share one feature: their local tax does not follow their activity at all. That is exactly the situation the mechanism targets, which is why it far more often concerns small businesses than large ones.

Conversely, a business whose value added is high relative to its premises will never reach the threshold. For it the calculation is made, triggers nothing, and there is no point redoing it each year without a change of circumstances.

The right reflex is therefore to do the calculation once, then revisit it only when something moves: a relocation, a heavy investment, a fall in activity, or a revision of the rates voted by the municipality.

That calculation takes half an hour at most once the accounts are drawn up. Set against relief that often repeats from year to year while the situation lasts, it is one of the most profitable checks in the tax file.
