Reforming the conjugal quotient

By Guillaume AllĂšgre and HĂ©lĂšne PĂ©rivier

As part of a review of family benefit programmes (the motivations for which are in any case debatable), the government has announced plans to reduce the cap on the family quotient benefit in the calculation of income tax (IR) from 2014. The tax benefit associated with the presence of dependent children in the household will be reduced from 2000 to 1500 euros per half share. Opening discussion on the family quotient should provide an opportunity for a more general review of how the family is taken into account in the calculation of income tax, and in particular the taxation of couples.

How are couples taxed today?

In France, joint taxation is mandatory for married couples and civil partners (and their children), who thus form part of one and the same household. It is assumed that members of a household pool their resources fully, regardless of who actually contributes them. By assigning two tax shares to these couples, the progressive tax scale is applied to the couple’s average revenue [(R1 + R2) / 2]. When the two spouses earn similar incomes, the marital quotient does not provide any particular advantage. In contrast, when the two incomes are very unequal, joint taxation provides a tax advantage over separate taxation.

In some configurations, separate taxation is more advantageous than joint taxation; this is due partly to the particular way that the employment bonus and tax reduction [1] operates, and to the fact that separate taxation can be used to optimize the allocation of the children between the two tax households, which by construction does not permit joint taxation. Tax optimization is complex, because it is relatively opaque to the average taxpayer. Nevertheless, in most cases, marriage (or a “PACS” civil partnership) provides a tax benefit: 60% of married couples and civil partners pay less tax than if they were taxed separately, with an average annual gain of 1840 euros, while 21% would benefit from separate taxation, which would save them an average of 370 euros (Eidelman, 2013).

Why grant this benefit just to married couples and civil partners?

The marital quotient is based on the principle that resources are fully pooled by the couple. The private contract agreed between two people through marriage or a PACS constitutes a “guarantee” of this sharing. In addition, the marriage contract is subject to a maintenance obligation between spouses, which binds them beyond the wedding to share part of their resources. However, the Civil Code does not link “marriage” to the “full pooling” of resources between spouses. Article 214 of the Civil Code provides that spouses shall contribute towards the expenses of the marriage “in proportion to their respective abilities”, which amounts to recognizing that the spouses’ abilities to contribute may be unequal. Since 1985, Article 223 has established the principle of the free enjoyment of earned income, which reinforces the idea that marriage does not mean that the spouses share the same standard of living: “each spouse is free to practice a profession, to collect earnings and wages and to spend them after paying the costs of the marriage”. The professional autonomy of the spouses and the right to dispose of their wages and salaries are fully recognized in the Civil Code, whereas the Tax Code is limited to an overview of the couple’s income and expenditures.

In addition, there is some dissonance between the social and the tax treatment of couples. The amount of the RSA benefit [income support] paid to a couple is the same whether they are married or common-law partners. As for the increased RSA paid to single mothers with children, being single means living without a spouse, including a common law partner. Cohabitation is a situation recognized by the social system as involving the pooling of resources, but not by the tax system.

Do couples actually pool their resources?

Empirical studies show that while married couples tend to actually pool all their income more than do common-law partners, this is not the case of everyone: in 2010, 74% of married couples reported that they pooled all their resources, but only 30% of PACS partners and 37% of common-law couples. Actual practice depends greatly on what there is to share: while 72% of couples in the lowest income quartile report pooling their resources fully, this is the case for only 58% of couples in the highest quartile (Ponthieux, 2012). The higher the level of resources, the less the couple pools them. Complete pooling is thus not as widespread as assumed: spouses do not necessarily share exactly the same standard of living.

Capacity to contribute and number of tax shares allocated

The tax system recognizes that resources are pooled among married couples and civil partners, and assigns them two tax shares. The allocation of these tax shares is based on the principle of ability to pay, which must be taken into account to be consistent with the principle of equality before taxation: in other words, the objective is to tax the standard of living rather than income per se. For a single person and a couple with the same incomes, the singleton has a higher standard of living than the couple, but due to the benefits of married life it is not twice as high. To compare the living standards of households of different sizes, equivalence scales have been estimated (Hourriez and Olier, 1997). The INSEE allocates a 1.5 share (or consumption unit) to couples and a 1 share to single people: so according to this scale, a couple with a disposable income of 3000 euros has the same standard of living as a single person with an income of 2000 euros. However, the marital quotient assigns two shares to married couples but one to the single person. It underestimates by 33% the standard of living of couples relative to single people, and therefore they are not taxed on their actual ability to contribute.

Moreover, once again there is an inconsistency between the treatment of couples by social policy and by fiscal policy: social security minima take into account the economies of scale associated with married life in accordance with the equivalence scales. The base RSA (RSA socle) received by a couple (725 euros) is 1.5 times greater than that received by a single person (483 euros). There is an asymmetry in the treatment of spouses depending on whether they belong to the top of the income scale and are subject to income tax, or to the bottom of the income scale and receive means-tested social benefits.

What family norms are encapsulated in the marital quotient?

The marital quotient was designed in 1945 in accordance with a certain family norm, that of Monsieur Gagnepain and Madame Aufoyer [“Mr Breadwinner and Ms Housewife”]. It contributed together  with other family programmes to encouraging this type of family organization, i.e. the one deemed desirable. Until 1982, tax was based solely on the head of the family, namely the man, with the woman viewed as the man’s responsibility. But far from being a burden on her husband, the wife produced a free service through the domestic work she performed. This home production (the care and education of children, cleaning, cooking, etc.) has an economic value that is not taxed. Single earner couples are thus the big winners in this system, which gives them an advantage over dual earner couples, who must pay for outsourcing part of the household and family work.

In summary, the current joint taxation system leads to penalizing single persons and common-law couples compared to married couples and civil partners, and to penalizing dual-earner couples compared to single-earner couples. The very foundations of the system are unfavourable to the economic liberation of women.

What is to be done?

The real situation of families today is multiple (marriage, cohabitation, etc.) and in motion (divorce, remarriage or new partnerships, blended families); women’s activity has profoundly changed the situation in the field. While all couples do not pool their resources, some do, totally or partially, whether married or in common law unions. Should we take this into account? If yes, how should this be done in light of the multiplicity of forms of union and the way they constantly change? This is the challenge we face in reforming the family norms and principles that underpin the welfare state. Meanwhile, some changes and rebalancing could be achieved.

Currently, the benefit from joint taxation is not capped by law. It can go up to 19,000 euros per year (for incomes above 300,000 euros, an income level subject to the highest tax bracket) and even to almost 32,000 euros (for incomes above 1,000,000 euros) if you include the benefit of joint taxation for the exceptional contribution on very high incomes. For comparison, we note that the maximum amount of the increase in the RSA for a couple compared to a person living alone is 2900 euros per year. The ceiling on the family quotient (QF), which is clear, is 1500 euros per half share. A cap on the marital quotient of 3000 euros (twice the cap on the QF) would affect only the wealthiest 20% of households (income of over 55,000 euros per year for a single-earner couple with two children). At this income level, it is likely that the benefit from joint taxation is related to an inequality in income that is the result of specialization (full or not) between the spouses in market and non-market production or that resources are not fully shared between the partners.

Another complementary solution would be to leave it up to every couple to choose between a joint declaration and separate declarations, and in accordance with the consumption scales commonly used to accord the joint declaration only 1.5 shares instead of 2 as today. The tax authorities could calculate the most advantageous solution, as households do not always choose the right option for them.

A genuine reform requires starting a broader debate about taking family solidarity into account in the tax-benefit system. In the meantime, these solutions would rebalance the system and turn away from a norm that is contrary to gender equality. At a time when the government is looking for room for fiscal maneuvering, why prohibit changing the taxation of couples?

[1] A tax reduction [décote]is applied to the tax on households with a low gross tax (less than 960 euros). As the reduction is calculated per household and does not depend on the number of persons included in the household, it is relatively more favourable for singles than for couples. It helps ensure that single people working full time for the minimum wage are not taxable. For low-income earners, the reduction thus compensùtes the fact that single persons are penalized by the marital quotient. No similar mechanism is provided for high-income earners.
