for 2005

This section summarizes important changes that take effect in 2005 and that could affect your estimated tax payments for 2005. More information on these and other changes can be found in Publication 553.


Taxmap/pubs/p505-010.htm#TXMP1a2032a7
Definition of dependent.

A dependent is either a qualifying child or a qualifying relative.

Qualifying child. In general, a qualifying child must meet all of the following conditions.

Qualifying relative. In general, a qualifying relative must meet all of the following conditions.

The following rules also apply in determining if a person is your dependent.

  1. If you are a dependent of another person in 2005, you cannot claim any dependents on your return.
  2. If the dependent is married, he or she cannot file a joint return unless the return is filed only as a claim for refund and no tax liability would exist for either spouse if they had filed separate returns.
  3. A dependent generally must be a U.S. citizen, U.S. national, or a resident of the United States, Canada, or Mexico.
  4. New tie-breaker rules apply if a child meets the conditions to be a qualifying child of two or more people and more than one person claims the child as a qualifying child.

Certain tax benefits, such as qualifying widow(er) filing status and medical and dental expenses, can still be claimed based on a person who is not your dependent if the only reason that person is not your dependent is because he or she is a qualifying relative who has gross income of $3,200 or more or because of items (1) or (2) above.


Taxmap/pubs/p505-010.htm#TXMP315b7df2
Head of household.

In general, you can use head of household filing status only if, as of December 31, 2005, you were unmarried or legally separated (according to your state law) under a decree of divorce or separate maintenance and you paid over half the cost of keeping up a home:

  1. That was the main home for all of 2005 of your parent whom you can claim as a dependent. Your parent did not have to live with you.
  2. In which you lived for more than half of the year with either of the following:
    1. Your qualifying child (defined above, but without regard to the exception for children of divorced or separated parents). This does not include a qualifying child who is married at the end of 2005 and is not your dependent because he or she either (i) filed a joint return, or (ii) is not a U.S. citizen, U.S. national, or a resident of the United States, Canada, or Mexico.
    2. Any other person whom you can claim as a dependent.

You cannot use head of household filing status for a person who is your dependent only because:

The rules under prior law allowing certain married persons living apart from their spouses for the last 6 months of the year to use head of household filing status also apply for 2005.

Retirement savings plans.

The following paragraphs highlight changes that affect individual retirement arrangements (IRAs) and pension plans. For more information, see Publication 590, Individual Retirement Arrangements (IRAs).

Traditional or Roth IRA contribution limits. The contribution limit to a traditional or Roth IRA for 2005 is increased to $4,000 ($4,500 if you are 50 or older).

Traditional IRA income limits. If you have a traditional IRA and are covered by a retirement plan at work, the amount of income you can have and not be affected by the deduction phaseout increases. The amounts vary depending on filing status.

Salary reduction contributions under a SIMPLE. For 2005, salary reduction contributions that your employer can make on your behalf under a SIMPLE plan are increased to $10,000 (up from $9,000 in 2004). For more information about salary reduction contributions, see How Much Can Be Contributed on Your Behalf? in Publication 590, chapter 3.

Additional salary reduction contributions to SIMPLE IRAs. For 2005, additional salary reduction contributions can be made to your SIMPLE IRA if you meet certain requirements. For more information, see How Much Can Be Contributed on Your Behalf? in Publication 590, chapter 3.

Taxmap/pubs/p505-010.htm#TXMP1d6f43d3
Credit for child and dependent care expenses.

Generally, a qualifying person for purposes of the credit for child and dependent care expenses is your qualifying child (defined above) who is under age 13, or your dependent or spouse who is physically or mentally incapable of caring for himself or herself and who lived with you for more than half of 2005. However, for a qualifying child or dependent, the special rule for children of divorced or separated parents does not apply, and the child is treated as a qualifying person only for the custodial parent. You no longer need to pay over half the cost of keeping up a home for the qualifying person.


Taxmap/pubs/p505-010.htm#TXMP456d2377
Deduction for domestic production activities.

You may be able to deduct up to 3% of your qualified production activities income from the following activities.

  1. Construction performed in the United States;
  2. Engineering or architectural services performed in the United States for construction projects in the United States; or
  3. Any lease, rental, license, sale, exchange, or other disposition of:
    1. Tangible personal property, computer software, and sound recordings that you manufactured, produced, grew, or extracted in whole or in significant part within the United States,
    2. Any qualified film you produced, or
    3. Electricity, natural gas, or potable water you produced in the United States.

The deduction does not apply to income derived from: the sale of food and beverages you prepare at a retail establishment; property you leased, licensed, or rented for use by any related person; or the transmission or distribution of electricity, natural gas, or potable water.

This deduction is allowed for alternative minimum tax purposes, but is not allowed in determining net earnings from self-employment.

Estimated tax safe harbor for higher income individuals.

If your adjusted gross income for 2004 was more than $150,000 ($75,000 if married filing a separate return), your withholding and estimated tax payments must be at least the smaller of 90% of your tax liability for 2005 or 110% of the tax shown on your 2004 return (provided your 2004 return covered all 12 months) to avoid an estimated tax penalty.


Taxmap/pubs/p505-010.htm#TXMP3b914541
Who must pay estimated tax.

You must pay estimated tax unless the total tax shown on your return minus the amount you paid through withholding (including excess social security and railroad retirement tax withholding) will be less than $1,000.

Taxmap/pubs/p505-010.htm#TXMP515bec73
Qualified dividends.

The maximum tax rate for qualified dividends is 15% (generally, 5% for people whose other income is taxed at the 10% or 15% rate). Use Worksheet 2.5 to figure your estimated tax for 2005 if you expect to receive qualified dividends during the year.

Introduction

Estimated tax is the method used to pay tax on income that is not subject to withholding. This includes income from self-employment, interest, dividends, alimony, rent, gains from the sale of assets, prizes, and awards. You also may have to pay estimated tax if the amount of income tax being withheld from your salary, pension, or other income is not enough.

Estimated tax is used to pay both income tax and self-employment tax, as well as other taxes and amounts reported on your tax return. If you do not pay enough through withholding or estimated tax payments, you may be charged a penalty. If you do not pay enough by the due date of each payment period (see When To Pay Estimated Tax, later), you may be charged a penalty even if you are due a refund when you file your tax return. For information on when the penalty applies, see chapter 4.

It would be helpful for you to keep a copy of your 2004 tax return and an estimate of your 2005 income nearby while reading this chapter.
