Supporting elderly parents can be rewarding, but also financially draining.

The Society of Louisiana CPAs points out that qualified taxpayers can get some assistance from Uncle Sam. Individuals who provide financial support for their parents may qualify for a dependency exemption on their tax returns. In addition, they may qualify for medical expense deductions as well as a credit for dependent care expenses.

Understanding dependency

Although most filers are familiar with claiming dependency exemptions for themselves, their spouses, and their children, fewer are aware of the tax rules governing dependency exemptions for a parent or other relative.

Under current tax law, if you provide more than half the costs of supporting a parent or other qualified relative, you may be entitled to a dependency exemption.

Support includes food, lodging, clothing, transportation, recreation, medical and dental care, and similar necessities.

Qualifying for the deduction

The parent or relative must be a U.S. citizen, or a resident of the U.S., Canada, or Mexico. Your parent need not live with you to qualify as a dependent. Certain other relatives, however, must reside with you in order for you to take a dependency exemption. The dependent must not file a joint return with anyone, unless the return is filed only to receive a refund for taxes paid.

Furthermore, the dependent’s gross income must be less than the personal exemption amount which is $2,900 for 2001 (this does not apply to your children who are less than age 19 or to full-time students under age 24).

Tax-exempt income does not count toward the personal exemption amount, nor does the tax-exempt part of Social Security.

(However, for the tax filing status of married filing separately, all social security is taxable.)

Making the most of the exemption

The dependent’s own funds are not considered support unless they are actually used for support.

For example, let’s suppose that, over the course of the year, your mother receives $4,800 in Social Security and $200 in interest.

Of this $5,000, she spends $4,000 for her support and saves the remaining $1,000. If you spend more than $4,000 for her support, you can claim her as a dependent even though she could have contributed more money.

Unless you specify otherwise, the IRS routinely allocates your contribution of support equally between both parents. If you provide less than half of the total support for both parents, you might consider supporting only one of them, the one with less income.

By making your check payable only to that parent, you may become eligible to claim at least one parent as a dependent.

Finally, to protect your dependency exemption, add up the numbers well before the end of the year.

That way, if you discover you are short of providing more than half of your parent’s support, you may be able to claim the exemption by spending an additional sum before year end.

Filing a multiple support agreement

In some cases, several siblings join together to support an elderly parent. If you and your siblings together contribute more than half your parent’s support, but no one of you provides more than 50 percent of that support, you can file a multiple support agreement.

A multiple support agreement allows any one of you who furnished more than 10 percent of the dependent’s support to claim the one available exemption, if the others agree. Each contributor signs a form 2120 and gives that form to the taxpayer who is claiming the exemption.

The taxpayer claiming the exemption then attaches the form(s) to his/her tax return. The person who claims the exemption can differ from year to year.

Deducting medical expenses

If you pay more than half your parent’s support, you may be able to deduct any medical expenses you pay on his or her behalf, even if your parent earned too much for you to claim a dependency exemption. You may add your parent’s qualifying medical expenses (including health insurance premiums) that you pay to your own medical expenses and deduct the expenses which exceed 7.5 percent of your adjusted gross income (AGI) if you itemize deductions.

Qualifying for the dependent credit

A dependent care tax credit is available for individuals who, in order to be able to work, pay someone to care for a mentally or physically disabled parent. The credit is a percentage, based on your AGI, of the amount of dependent care expenses you pay.

Expenses for care of a disabled dependent also may qualify for a medical deduction. You must choose to take an expense as either an itemized deduction or as a dependent care credit, but not both.

If you have questions regarding dependency exemptions, deductions or the dependent care credit, you should consult a CPA.
