CHANGING YOUR FILING STATUS
Very specific rules apply to whether you can change your filing status by amending your return.
Please refer to IRS Publication 504, Divorced or Separated Individuals for more information. New
Mexico law does not permit you to change your filing status by an amended state return unless
you attach your amended federal return.
Rules and regulations too complicated to list in a general publication on filing status and
community property may require you to consult an attorney or accountant well acquainted with
community property law. Please also review IRS Publication 504, Divorced or Separated
Individuals.
ENDING THE MARITAL COMMUNITY
With respect to income, New Mexico (and the federal government, because it defers to state law
in this matter) requires community property to retain its character until the date of a decree or
court order ending the marital community. When the court order is final, all income from what was
once community property becomes separate income. Although a court order may be entered long
before the divorce is final, it can dissolve the community and the community character of income
from property. See Sections 40-4-3 and 40-3-8, NMSA 1978.
You and your spouse report half the combined gain from the sale of community property. Your
court order, decree, or judgment may specify whether you or your spouse reports the entire gain.
When you make a community property allocation on your federal return, submit copies of federal
form 1040 or 1040A to the state accompanied by any federal schedules reflecting the division.
See IRS Publication 504, Divorced or Separated Individuals. (See the references on page 1.)
Include all affected social security numbers. Continue to allocate community income on a 50-50
basis until the court order is filed. Once it is filed, the terms of the court order are binding. Each
spouse is taxed on half the community income for the part of the year before the community ends.
When you file separately, list the community property allocation plus whatever income you have
from separate sources, provided that there has been no mixing of funds from separate property.
Funds from separate property must be easily traced as separate funds.
Each spouse should maintain separate savings and checking accounts
immediately and start keeping separate books as soon as possible.
Whatever filing status you choose, plan ahead. Provide each other with copies of prior-year tax
returns, wage and withholding statements, and other records necessary to prepare current
income tax returns. If you and your spouse are not on speaking terms, do this through your
attorneys or a responsible third party.
When property cannot be identified as separate, the law presumes it is community property.
According to community property law in New Mexico, each spouse owns an undivided equal
interest in all community property. All community property belongs as much to one of you as to the
other. After the community property allocation, however, each of you owns 100% of the property
awarded to you rather than 50% of all property. This is important. If you file separately while you
are still legally married, report half of all combined community income on your own return. Your
spouse reports the other half on his or her return. You also must identify and report separate
income, expenses, deductions, exemptions, and credits. As stated, once a court order is entered,
the terms of the order may pre-empt a 50-50 allocation.
