NEW MEXICO PERSONAL INCOME TAX
Most New Mexico income tax laws are based on federal income tax laws. When filing New Mexico
personal income tax returns, including those of divorced or separated taxpayers, the first step is to
complete a federal return (form 1040 or 1040A and all necessary schedules). The Internal
Revenue Service requires you to decide your filing status and exemptions for yourself and
dependent children. A taxpayer filing a New Mexico income tax return uses the same filing status
and number of exemptions for New Mexico as for the federal return (Regulation 3.3.12.12 NMAC).
IRS Publication 504, Divorced or Separated Individuals, and IRS Publication 555, Community
Property, are helpful to review before you fill out your return. Look for them on the IRS website at
www.irs.gov.
COMMUNITY PROPERTY
New Mexico residents, including part-year residents, should note two very important facts:
1. New Mexico is a community property state.
2. New Mexico does not recognize common-law marriages. You must be legally
married to file a joint return or to realize any division of community property
upon divorce. Unless legally married, you are single, no matter how much you
contribute to a relationship, its property or income, or for how long. If you are
legally married in another state under the laws of that state, the legal marriage
transfers to New Mexico under Section 40-1-4 NMSA 1978.
In a community property state, all assets and liabilities you acquire during the marriage that are
not separate property are community property. For a thorough definition of community property
please refer to Sections 40-3-8 (B) and 40-3-8(C) NMSA 1978.
Community income is income from community property you receive during the marriage from non-
business sources (e.g. wages, salaries, dividends, interest, royalties, rents, etc.) or business
sources (e.g., Schedule C gross receipts or farm income) while you are residents of New Mexico.
SEPARATE PROPERTY
Separate property is real estate or personal property including gifts, inheritance, savings, rental
income, etc. you acquire before the marriage, or non-business or business income you receive
after the marriage is dissolved. If either you or your spouse receives a gift or an inheritance as
sole-and-separate property during the marriage, that property remains sole and separate. You
may also acquire property separately during a marriage when you buy it with separate funds, or
you exchange separate property for other separate property. New Mexico allows you at any time
during your marriage to designate separate property through a formal, written agreement between
you and your spouse. For a more thorough definition of separate property, please refer to Section
40-3-8(A), NMSA 1978.
Separate income is income from separate property. It is credited to the spouse who receives the
property. When a court order decrees a community property division, the date of the decree
determines the end of community property and income and the beginning of separate property
and income. Do not mix funds from separate property in such a way that the funds are
indistinguishable. If you do, the funds may become community property. This is true whether a
divorce is pending or not.
New Mexico Taxation and Revenue Department
FYI-310 Rev. 5/2018 Page 3
There are rules and exceptions too complicated to list in a general publication on separate and
community property. If you believe that certain assets and liabilities are sole and separate, please
consult an accountant or attorney well acquainted with community property law. You may also
review IRS Publication 555, Community Property, before you fill out your return.
FEDERAL AND STATE FILING STATUS
If your divorce becomes final during the tax year for which you are filing, the matter is simple.
Unless you have remarried, you are considered unmarried for the whole year. Your status on
December 31 governs the full year even if the divorce becomes final on December 31. Report half
the combined community income on your return regardless of your filing status if you received any
community income while you were still married.
You may qualify to file as head of household if you were unmarried on December 31 and provided
more than half the cost of maintaining a home that was the principal home for longer than six
months for yourself and a qualified household member. IRS Publication 504, Tax Information for
Divorced or Separated Individuals, lists the categories of people you can include in your
household for tax purposes.
A couple whose divorce will not be final until the following year faces another decision: whether to
file "married filing jointly" or "married filing separately" while the divorce is pending.
FILING JOINTLY
The Internal Revenue Service offers relief from liability in certain situations. See Section 6015 of
the Internal Revenue Code. The federal relief includes innocent spouse, separation of liabilities, or
equitable relief. Contact the Internal Revenue Service if you want this kind of relief. New Mexico
recognizes only relief for an innocent spouse and separation of liabilities, and only when it is in
writing.
Innocent Spouse Relief
If your spouse underreported the amount of tax on your jointly filed return, you may apply to the
Internal Revenue Service for relief from additional federal tax that may be due. Please refer to IRS
Publication 971, Innocent Spouse Relief (And Separation of Liability and Equitable Relief). (See
references on page 1.) Although state law prohibits the Department from forgiving the additional
state taxes due, the Department Secretary has the discretion to decline to bring collection actions
against the “innocent spouse” when it is unfair to hold that spouse liable (Sec. 7-1-17.1 NMSA
1978, Regulation 3.1.12.13 NMAC).
Separation of Liabilities Relief
A spouse who filed a joint return may be relieved of a portion of the tax liability if the Internal
Revenue Service determines in writing that there is a separation of liabilities because the
individuals are no longer married, or they are legally separated. The IRS makes the “separation of
liabilities” determination according to Section 6015(c) of the Internal Revenue Code. New Mexico
honors the determination. Relief is only for part of the liability.
New Mexico Taxation and Revenue Department
FYI-310 Rev. 5/2018 Page 4
FILING SEPARATELY
You and your spouse may choose "married filing separately" because you cannot get along well
enough to cooperate on a joint return. Perhaps you had considerable amounts of sole-and-
separate property that you brought to the marriage or acquired as sole-and-separate property
after the marriage.
Many couples erroneously believe they can file jointly for the state and separately for the federal
government. This is not true. You can file “married filing separatelyfor state tax purposes only if
you choose the same status for your federal tax. New Mexico residents who are still legally
married but legally separated (or whose divorce is pending) may elect to file separately. Unless a
court order directs otherwise, each must report half the combined community income, deductions,
and credits in addition to any separate income and deductions. Please attach the federal
worksheet and your 1040 or 1040A return to your state return showing how you allocated your
income and deductions. You cannot take certain federal deductions if you file separate returns.
Please refer to IRS Publication 504, Divorced or Separated Individuals, for more information.
There are special provisions for some community income:
Special Treatment of Certain Community Income
A spouse may not have to report half of certain combined community income (e.g., wages,
salaries, professional fees, pay for professional services, partnership income, trade or business
income and Social Security benefits) if all the following conditions exist:
1. You and your spouse lived apart all year;
2. You and your spouse did not file a joint return;
3. You and your spouse had wages, salaries, and professional fees that are
community income;
4. You and your spouse did not transfer, directly or indirectly, any of the wages, salaries,
or professional fees between you during any part of the year.
Report half the total of all other types of community income (dividends, rents, royalties, or gains) if
you meet all the above criteria.
Relief from Separate Return Liability for Community Income
A spouse who filed a married-filing-separately return may be relieved of reporting an item of
community property if all the following conditions exist:
1. You did not file a joint return for the tax year;
2. You did not include an item of community income in gross income on your separate
return;
3. You establish that you did not know about and had no reason to know about that
community income;
4. Under all facts and circumstances it would not be fair to include the item of
community income in your gross income.
Community Income Attributable to You
Under certain conditions all community income may be attributable to only one spouse. Assuming
you were married during the year, you may have to report the full amount of the item of
community income if you filed separately or as head of household. See Section 66 of the Internal
New Mexico Taxation and Revenue Department
FYI-310 Rev. 5/2018 Page 5
Revenue Code at www.irs.gov. The following conditions must exist for all community income to
belong to you:
1. You did not file a joint return;
2. You treated the item as if only you are entitled to the income, and
3. You did not notify your spouse of the nature and amount of the income by the due date
for filing the return, including extensions of time to file.
Examples of Allocation of Community Income
Example 1. A New Mexico full-year resident and a Colorado resident (non-resident of New
Mexico) are married and file a joint return. The New Mexico resident has wage income from
employment in Texas. Because New Mexico is a community property state and the resident
spouse is domiciled in New Mexico, the resident spouse’s wage income is community property.
Half the wage income from employment in Texas is the property of each spouse. The instructions
for PIT-B, line 1, require that half of the New Mexico resident’s wage income is allocated in full to
New Mexico, even if the income was not earned in New Mexico. The non-resident spouse’s share
of the community wage income is not allocated to New Mexico, because the income is not from
services performed in New Mexico.
Example 2. Use the same facts as example 1, except the wage income is the separate income of
the New Mexico resident spouse due to a separation agreement. All wage income is allocated to
New Mexico, because the spouse entitled to the benefit of the entire amount of wage income is a
resident of New Mexico. The New Mexico resident must allocate this wage income according to
the line instructions for a resident taxpayer on PIT-B, line 1.
Example 3. Again, use the same facts as example 1, except wages from employment in Texas
were earned by the non-resident spouse who was domiciled in Texas. Because the non-resident
spouse is domiciled in a community property state, the wage income is community property.
When both spouses are residents of community property states or both spouses are residents of
non-community property states, special allocation and apportionment rules are not needed. Half of
the community income is allocated to New Mexico, based on the instructions for the resident
spouse’s share of the community income. The other half of the community income is not allocated
to New Mexico, based on the instructions for the non-resident spouse’s share of the community
income.
Example 4. If both spouses are residents of New Mexico, all community wage income is allocated
to New Mexico.
HEAD OF HOUSEHOLD
You may be eligible to file as head of household if you were unmarried on December 31 and
provided more than half the cost of maintaining a principal home for longer than six months for
yourself and a qualifying household member. IRS Publication 504, Divorced or Separated
Individuals, lists the categories of persons you may include in your household for tax purposes.
Tax rates for heads of household are lower than for single or married-filing-separately taxpayers.
You may file as head of household for state tax purposes only if you file as head of household for
federal purposes. Those married during any part of the year report half the combined community
income, deductions and credits in addition to any separate income and deductions.
New Mexico Taxation and Revenue Department
FYI-310 Rev. 5/2018 Page 6
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.
New Mexico Taxation and Revenue Department
FYI-310 Rev. 5/2018 Page 7
For information on ending the marital community, see IRS Publication 555, Community Property,
and IRS Publication 504, Divorced or Separated Individuals.
EXEMPTIONS, DEDUCTIONS, AND CREDITS
Determinations of exemptions you may take and dependents you may claim occur under federal
rules on your federal form 1040 or 1040A. You must do the same for state tax purposes. If you are
still legally married, a full exemption is allowed for each spouse. Note, however, that a spouse is
never a dependent no matter how little income the spouse may earn. Each person filing a
separate or head-of-household return may claim a personal exemption. On married-filing-
separately returns you may each claim an exemption. Take an exemption for your spouse only if
your spouse had no gross income and was not a dependent of another taxpayer. The question of
dependents is another matter. It is important to specify dependency status as a part of the divorce
settlement before the divorce becomes final. Again, for information about allocation of federal
deductions and credits, please consult IRS Publication 555, Community Property.
DEPENDENT CHILDREN
You may take an exemption for each dependent who meets the five-part test of dependency in
Section 152 of the Internal Revenue Code. This is set out in IRS Publication 504, Divorced or
Separated Individuals. Usually the parent with physical custody of the dependent child for the
larger portion of the calendar year claims the federal and state exemptions for the child, but only if
one or both of you together supply more than half the child's support and the child was in the
custody of either parent for more than half the calendar year. This means, for example, that
neither can claim the exemption for the child if the child lives with a grandparent who provides
more than half the child's support. When a divorce or separation occurs during a tax year, the
parent having custody of the child for the greater portion of the remainder of the tax year usually
claims the exemption.
There are times when the non-custodial parent may claim the exemption, especially when the
custodial parent cannot clearly establish that he or she provided the greater amount of support.
Joint Custody
The question of joint custody may need an accountant’s or an attorney’s advice on dependency
status and child support. Some circumstances require certain forms waiving the dependency
claim on the part of one parent. This is a federal determination. Address questions about specific
situations to the IRS. The web site is www.irs.gov.
STATE TAX CREDITS AND REBATES
You may take the full credits and rebates available when you file a joint return. If you elect
married-filing-separately status or head-of-household status, then you may each take only one-
half the total credits or rebates. Your court order may specify which party may take the available
credits and rebates if you are legally separated and not filing a joint return. Please take the credits
or rebates and attach the court order to your state return if the court order specifies which of you is
entitled to the credits or rebates.
CHILD SUPPORT ENFORCEMENT
New Mexico Taxation and Revenue Department
FYI-310 Rev. 5/2018 Page 8
When child support is not paid by a parent who is required by court order to pay, the state of New
Mexico Taxation and Revenue Department by law must intercept a personal income tax refund
due to that parent and direct it through the Human Services Department (HSD) to the custodial
parent or guardian. When court-ordered child support is not received, the person who is supposed
to receive it should contact HSD for assistance. New Mexico participates in a nationwide network
linking HSD to its counterparts in other states. The custodial parent should call HSD at 1(800)759-
KIDS (5437) whether or not the non-paying spouse lives in New Mexico.
