Tax on Income in Community Property States

When married couples file separate income tax returns, a special problem arises. Tax is not computed just on income earned by each spouse. Instead, wages and other income earned by a husband and wife must be allocated according to state law, as will income earned from property held by a married couple, either jointly or separately.

The law in nine states is based on a community property system. The property rights of married couples are different in these states, than the property rights of married couples living in the common law states. Under the community property system, property is deemed to be either separate propertyseparate propertyProperty obtained by gift, inheritance, or prior to marriage. or community property. Separate property includes property acquired by a spouse before marriage or received after marriage as a gift or inheritance. All other property owned by a married couple is deemed to be community property. For federal income tax purposes, each spouse is automatically taxed on half of the income from community property.

The tax treatment of income from separate property depends on the taxpayer‘s state of residence. In four community property states, half of the income from community property and half of the income of most separate property will be taxed to each spouse.

In the other five community property states, income on separate property is “separate income” and is reported in full on the tax return of the spouse who owns the property. Income such as nontaxable dividends or royalties from mineral interests assumes the classification of the asset from which the income is earned. Capital gains also retain their classification based on the classification of the property from which the gain arises. The nine states that use the community property system are listed in Table 6.1, “Community Property States”.

In all of the community property states, income from salary and wages is generally treated as having been earned one-half by each spouse.

To simplify problems that could arise when married spouses residing in a community property state do not live together, the tax law contains an exception to the above community property rules. Under this special provision, a spouse will be taxed only on his or her actual earnings from personal services. For this provision to apply, the following conditions must be satisfied:

  1. The individuals must live apart for the entire year,

  2. They must not file a joint return, and

  3. No portion of the earned income may be transferred between the spouses.

Another provision addresses the problem of spouses who fail to qualify for the above special exception because they do not live apart for the entire year. In certain cases, a spouse who fails to include in income his or her share of community income, as required by the community property laws, may be relieved of any liability related to this income. To be granted relief, the taxpayer must not know of or have reason to know of the omitted community property income.
