Pub. 17, Your Federal Income Tax 2005 Tax Year

Publication 17 - Introductory Material


All material in this publication may be reprinted freely. A citation to Your Federal Income Tax (2005) would be appropriate.

The explanations and examples in this publication reflect the interpretation by the Internal Revenue Service (IRS) of:

  • Tax laws enacted by Congress,

  • Treasury regulations, and

  • Court decisions.

However, the information given does not cover every situation and is not intended to replace the law or change its meaning.

This publication covers some subjects on which a court may have made a decision more favorable to taxpayers than the interpretation by the IRS. Until these differing interpretations are resolved by higher court decisions or in some other way, this publication will continue to present the interpretations by the IRS.

All taxpayers have important rights when working with the IRS. These rights are described in Your Rights as a Taxpayer in the back of this publication.

Reminders

Listed below are important reminders and other items that may help you file your 2005 tax return. Many of these items are explained in more detail later in this publication.

Write in your social security number. To protect your privacy, social security numbers (SSNs) are not printed on the peel-off label that comes in the mail with your tax instruction booklet. This means you must enter your SSN in the space provided on your tax form. If you filed a joint return for 2004 and are filing a joint return for 2005 with the same spouse, enter your names and SSNs in the same order as on your 2004 return. See chapter 1. Victim of identity theft. If you believe someone has assumed your identity to file federal income tax returns, or to commit other tax fraud, call 1-800-829-0433. Victims of identity theft who are having trouble filing their returns should call the IRS Taxpayer Advocates Office at 1-877-777-4778. You should also know that the IRS does not initiate communication with taxpayers through email. If you do receive this type of request, it may be an attempt by identity thieves to get your private tax information.

Taxpayer identification numbers. You must provide the taxpayer identification number for each person for whom you claim certain tax benefits. This applies even if the person was born in 2005. Generally, this number is the person's social security number (SSN). See chapter 1.

Foreign source income. If you are a U.S. citizen with income from sources outside the United States (foreign income), you must report all such income on your tax return unless it is exempt by U.S. law. This is true whether you reside inside or outside the United States and whether or not you receive a Form W-2 or 1099 from the foreign payer. This applies to earned income (such as wages and tips) as well as unearned income (such as interest, dividends, capital gains, pensions, rents and royalties). If you reside outside the United States, you may be able to exclude part or all of your foreign source earned income. For details, see Publication 54, Tax Guide for U.S. Citizens and Resident Aliens Abroad.

Earned income credit. You can choose to include combat pay in your earned income for purposes of computing this credit. If you are married, each of you can make this election separately. Form 8836. If you received Form 8836, Qualifying Children Residency Statement, you have been selected to participate in the EIC certification program. See chapter 36.

Advance earned income credit. If a qualifying child lives with you and you expect to qualify for the earned income credit in 2006, you may be able to get part of the credit paid to you in advance throughout the year (by your employer) instead of waiting until you file your tax return. See chapter 36.

Sales tax deduction. You can choose to deduct state and local general sales taxes instead of state and local income taxes as an itemized deduction on Form 1040, Schedule A. See chapter 22.

Tax Computation Worksheet. If your taxable income is $100,000 or more, figure your tax using the Tax Computation Worksheet. The Tax Computation Worksheet is found near the end of this publication immediately following the Tax Rate Schedules. (The Tax Rate Schedules are shown so you can see the tax rate that applies to all levels of taxable income. Do not use the Tax Rate Schedules to figure your tax.)

Joint return responsibility. Generally, both spouses are responsible for the tax and any interest or penalties on a joint tax return. In some cases, one spouse may be relieved of that responsibility for items of the other spouse that were incorrectly reported on the joint return. See chapter 2.

Include your phone number on your return. To promptly resolve any questions we have in processing your tax return, we would like to be able to call you. Please enter your daytime telephone number on your tax form next to your signature.

Third party designee. You can check the “Yes” box in the “Third Party Designee” area of your return to authorize the IRS to discuss your return with a friend, family member, or any other person you choose. This allows the IRS to call the person you identified as your designee to answer any questions that may arise during the processing of your return. It also allows your designee to perform certain actions. See chapter 1.

Payment of taxes.  Make your check or money order payable to “United States Treasury.” You can pay your taxes by credit card, using the Electronic Federal Tax Payment System (EFTPS), or, if you file electronically, by electronic funds withdrawal. See chapter 1.

Faster ways to file your return. The IRS offers fast, accurate ways to file your tax return information without filing a paper tax return. You can use IRS e-file (electronic filing). See chapter 1.

Free electronic filing.  You may be able to file your 2005 taxes online for free thanks to an electronic filing agreement. See chapter 1.

Change of address. If you change your address, you should notify the IRS. See Change of Address, under What Happens After I File, in chapter 1.

Private delivery services. You may be able to use a designated private delivery service to mail your tax returns and payments. See chapter 1.

Refund on a late filed return. If you were due a refund but you did not file a return, you generally must file your return within 3 years from the date the return was due (including extensions) to get that refund. See chapter 1.

Privacy Act and paperwork reduction information.  The IRS Restructuring and Reform Act of 1998, the Privacy Act of 1974, and the Paperwork Reduction Act of 1980 require that when we ask you for information we must first tell you what our legal right is to ask for the information, why we are asking for it, how it will be used, what could happen if we do not receive it, and whether your response is voluntary, required to obtain a benefit, or mandatory under the law. A complete statement on this subject can be found in your tax form instruction booklet.

Customer service for taxpayers expanded.  The Internal Revenue Service has expanded customer service for taxpayers. Through the agency's Everyday Tax Solutions service, you can set up a personal appointment at the most convenient Taxpayer Assistance Center, on the most convenient business day. See How To Get Tax Help in the back of this publication.

Treasury Inspector General for Tax Administration.  If you want to confidentially report misconduct, waste, fraud, or abuse by an IRS employee, you can call 1-800-366-4484 (1-800-877- 8339 for TTY/TDD users). You can remain anonymous.

Photographs of missing children. The Internal Revenue Service is a proud partner with the National Center for Missing and Exploited Children. Photographs of missing children selected by the Center may appear in this publication on pages that would otherwise be blank. You can help bring these children home by looking at the photographs and calling 1-800-THE-LOST (1-800-843-5678) if you recognize a child.

Introduction

This publication covers the general rules for filing a federal income tax return. It supplements the information contained in your tax form instruction booklet. It explains the tax law to make sure you pay only the tax you owe and no more.

How this publication is arranged.   This publication closely follows Form 1040, U.S. Individual Income Tax Return. It is divided into six parts which cover different sections of Form 1040. Each part is further divided into chapters which generally discuss one line of the form. Do not worry if you file Form 1040A or Form 1040EZ. Anything included on a line of either of these forms is also included on Form 1040.

  The table of contents inside the front cover and the index in the back of the publication are useful tools to help you find the information you need.

  5. Other general information.

It will help you identify which filing status you qualify for, whether you can claim any dependents, and whether the income you receive is taxable. The publication goes on to explain the standard deduction, the kinds of expenses you may be able to deduct, and the various kinds of credits you may be able to take to reduce your tax.
