To ensure they meet their tax obligations, taxpayers should file accurate tax returns. If a taxpayer makes an error on their tax return, it will likely take longer to process and could delay a refund. Taxpayers can avoid many common errors by filing electronically, the most accurate way to file a tax return. All taxpayers can use IRS Free File.

Here are common errors to avoid when preparing a tax return:

• Missing or inaccurate Social Security Numbers. Be sure to enter each SSN on a tax return exactly as printed on the Social Security card.
• Misspelled names. Spell all names listed on a tax return exactly as listed on the taxpayers’ Social Security cards.
• Filing status.  Some taxpayers claim the wrong filing status, such as Head of Household instead of Single. The Interactive Tax Assistant on IRS.gov can help taxpayers choose the correct status. E-file software also helps prevent mistakes.
• Math mistakes.  Math errors are common, ranging from simple addition and subtraction to more complex items. Figuring the taxable portion of a pension, IRA distribution or Social Security benefits is more difficult and results in more errors. Taxpayers should always double check their math. Better yet, tax preparation software does it automatically.
• Figuring credits or deductions. Taxpayers can make mistakes figuring their Earned Income Tax Credit, Child and Dependent Care Credit, the standard deduction and other items. Follow the instructions carefully. For example, a taxpayer who’s 65 or older, or blind, should claim the correct, higher standard deduction, if not itemizing. The IRS Interactive Tax Assistant can help determine if a taxpayer is eligible for tax credits or deductions.
• Incorrect bank account numbers. Taxpayers who are due a refund should choose direct deposit for ease and convenience, but the IRS cautions taxpayers to use the right routing and account numbers on the tax return.
• Unsigned forms. An unsigned tax return isn’t valid. Both spouses must sign a joint return. Taxpayers can avoid this error by filing their return electronically and digitally signing it before sending it to the IRS. Taxpayers who are using a tax software product for the first time will need their adjusted gross income from their 2016 tax return to file electronically. Taxpayers who are using the same tax software they used last year usually will not need to enter prior-year information to electronically sign their 2017 tax return. 
• Filing with an expired ITIN. The IRS will process and treat as timely a return filed with an expired Individual Tax Identification Number, but won’t allow any exemptions or credits. Taxpayers will receive a notice explaining that an ITIN must be current before the IRS will pay a refund. Once the taxpayer renews the ITIN, the IRS will process exemptions and credits and pay an allowed refund. ITIN expiration and renewal information is available on IRS.gov.

The IRS urges people not to overlook the Child and Dependent Care Tax Credit. Eligible taxpayers may be able claim it if they paid for someone to care for a child, dependent or spouse last year.

Taxpayers can use the IRS Interactive Tax Assistant tool, Am I Eligible to Claim the Child and Dependent Care Credit?, to help determine if they are eligible to claim the credit for expenses paid for the care of an individual to allow the taxpayer to work or look for work.

Eight other key points about this credit include:

1. 1. Work-Related Expenses. The care must have been necessary so a person could work or look for work. For those who are married, the care also must have been necessary so a spouse could work or look for work. This rule does not apply if the spouse was disabled or a full-time student.
2. 2. Qualifying Person. The care must have been for “qualifying persons.” A qualifying person can be a child under age 13. A qualifying person can also be a spouse or dependent who lived with the taxpayer for more than half the year and is physically or mentally incapable of self-care.
3. 3. Earned Income. A taxpayer must have earned income for the year, such as wages from a job. For those who are married and file jointly, the spouse must also have earned income. Special rules apply to a spouse who is a student or disabled.
4. 4. Credit Percentage / Expense Limits. The credit is worth between 20 and 35 percent of allowable expenses. The percentage depends on the income amount. Allowable expenses are limited to $3,000 for paid care of one qualifying person. The limit is $6,000 if the taxpayer paid for the care of two or more.
5. 5. Dependent Care Benefits. Special rules apply for people who get dependent care benefits from their employer. Form 2441, Child and Dependent Care Expenses, has more on these rules. File the form with a tax return.
6. 6. Qualifying Person’s SSN. The Social Security number of each qualifying person must be included to claim the credit.
7. 7. Care Provider Information. The name, address and taxpayer identification number of the care provider must be included on the return.
8. 8. IRS Free File. Taxpayers are encouraged to use IRS Free File to prepare and e-file their federal tax returns, including Form 2441. Free File is easy, fast and available only at IRS.gov/freefile.

Taxpayers who pay someone to come to their home and care for their dependent or spouse may be a household employer and may have to withhold and pay Social Security and Medicare tax and pay federal unemployment tax. See Publication 926, Household Employer’s Tax Guide.

Taxpayers should keep a copy of their tax return. Beginning in 2017, taxpayers using a software product for the first time may need their Adjusted Gross Income (AGI) amount from their prior-year tax return to verify their identity. Taxpayers can learn more about how to verify their identity and electronically sign tax returns at https://www.irs.gov/individuals/electronic-filing-pin-request.

Taxpayers who made certain energy efficient improvements to their home last year may qualify for a tax credit this year. Here are some key facts to know about home energy tax credits:

Non-Business Energy Property Credit

Part of this credit is worth 10 percent of the cost of certain qualified energy-saving items added to a taxpayer’s main home last year. Qualified improvements include adding insulation, energy-efficient exterior windows and doors, and certain roofs. Do not include the cost to install these items.

The other part of the credit is not a percentage of the cost. It includes the installation costs of certain high-efficiency heating and air-conditioning systems, high-efficiency water heaters and stoves that burn biomass fuel. The credit amount for each type of property has a different dollar limit.

This credit has a maximum lifetime limit of $500. Taxpayers may only use $200 of this limit for windows.

A taxpayer’s main home must be located in the U.S. to qualify for the credit. The non-business energy property credit is only available for existing homes.

Be sure to have the written certification from the manufacturer that their product qualifies for this tax credit. They usually post it on their website or include it with the product’s packaging. Taxpayers can use this to claim the credit. Do not attach it to a tax return. Keep it with tax records.

Taxpayers may claim the credit on their 2016 tax return if they didn’t reach the lifetime limit in past years. Under current law, Dec. 31, 2016, was the deadline for qualifying improvements to the taxpayer’s main U. S. home.

Residential energy efficient property credit

This tax credit is 30 percent of the cost of alternative energy equipment installed on or in a home. This includes the cost of installation.

Qualified equipment includes solar hot water heaters, solar electric equipment, wind turbines and fuel cell property.

There is no dollar limit on the credit for most types of property. If the credit is more than the tax owed, carry forward the unused portion of this credit to next year’s tax return.

The home must be in the U.S. It does not have to be a taxpayer’s main home, unless the alternative energy equipment is qualified fuel cell property. The residential energy efficient property credit is available for both existing homes and homes under construction.

This credit is available through 2016.

Use Form 5695, Residential Energy Credits, to claim these credits. For more information on this topic, refer to the form’s instructions. Get IRS forms anytime on IRS.gov/forms.

Taxpayers should keep a copy of their tax return. Beginning in 2017, taxpayers using a software product for the first time may need their Adjusted Gross Income (AGI) amount from their prior-year tax return to verify their identity. Taxpayers can learn more about how to verify their identity and electronically sign tax returns at Validating Your Electronically Filed Tax Return.

A name change can have an impact on taxes. All the names on a taxpayer’s tax return must match Social Security Administration records. A name mismatch can delay a tax refund. Here’s what taxpayers should know if they changed their name:

*Reporting Name Changes. Got married and now using a new spouse’s last name or hyphenate a name? Divorced and now back to using a former last name? In either case, taxpayers should notify the SSA of a name change. That way the new name on IRS records will match the SSA records.

*Making dependent’s name change. Notify the SSA if a dependent had a name change. For example, if a taxpayer adopted a child and the child’s last name changed. If the child does not have a Social Security number, the taxpayer may use an Adoption Taxpayer Identification Number on their tax return. An ATIN is a temporary number. Apply for an ATIN by filing Form W-7A, Application for Taxpayer Identification Number for Pending U.S. Adoptions, with the IRS. Visit IRS.gov to get the form.

*Getting a New SS Card. File Form SS-5, Application for a Social Security Card. The form is on SSA.gov or by calling 800-772-1213. The taxpayer’s new card will reflect the name change.

All taxpayers should keep a copy of their tax return. Beginning in 2017, taxpayers using a software product for the first time may need their Adjusted Gross Income (AGI) amount from their prior-year tax return to verify their identity. Taxpayers can learn more about how to verify their identity and electronically sign tax returns at Validating Your Electronically Filed Tax Return.

Most taxpayers claim the standard deduction when they file their federal tax return. However, some filers may be able to lower their tax bill by itemizing. Find out which way saves the most money by figuring taxes both ways.

The IRS offers the following six tips to help taxpayers decide:

1. Use IRS Free File. Most taxpayers qualify to use free, brand-name software to prepare and file their federal tax returns electronically. IRS Free File is the easiest way to file. Free File software helps taxpayers determine if they should itemize. It files the right tax forms based on the answers the taxpayer provides. Free File software does the math and allows the user to e-file the tax return – for free.

Taxpayers can check on other e-file options if they can’t use Free File.

2. Figure Your Itemized Deductions.  Taxpayers need to add up deductible expenses they paid during the year. These may include expenses such as:

• Home mortgage interest
• State and local income taxes or sales taxes (but not both)
• Real estate and personal property taxes
• Gifts to charities
• Casualty or theft losses
• Unreimbursed medical expenses
• Unreimbursed employee business expenses

Special rules and limits apply. Visit IRS.gov and refer to Publication 17, Your Federal Income Tax, for more details.

3. Know The Standard Deduction. If a taxpayer doesn’t itemize, then the basic standard deduction for 2016 depends on their filing status. If the taxpayer is:

• Single – $6,300
• Married Filing Jointly – $12,600
• Head of Household – $9,300
• Married Filing Separately – $6,300
• Qualifying Widow(er) – $12,600

If a taxpayer is 65 or older, or blind, the standard deduction is higher than the previous amounts. The deduction may be limited if the taxpayer can be claimed as a dependent.

4. Check the Exceptions. There are some situations where the law does not allow a person to claim the standard deduction. This rule applies if the taxpayer is married filing a separate return and their spouse itemizes. In this case, the taxpayer’s standard deduction is zero and they should itemize any deductions. See Publication 17 for more on these rules.

5. Use the IRS ITA Tool. Go to IRS.gov and use the Interactive Tax Assistant tool. It can help determine whether a taxpayer can use the standard deduction. It can also help a filer figure their eligibility for certain itemized deductions.

6. File the Right Forms.  For a taxpayer to itemize their deductions, they must file Form 1040 and Schedule A, Itemized Deductions. Filers can take the standard deduction on Forms 1040, 1040A or 1040EZ.

All taxpayers should keep a copy of their tax return.  Beginning in 2017, taxpayers using a software product for the first time may need their Adjusted Gross Income (AGI) amount from their prior-year tax return to verify their identity. Taxpayers can learn more about how to verify their identity and electronically sign tax returns at Validating Your Electronically Filed Tax Return.

Most people file their tax return because they have to, but even if you don’t, there are times when you should. You may be eligible for a tax refund and not know it. This year, there are a few new rules for some who must file. Here are six tax tips to help you find out if you should file a tax return:

1. General Filing Rules.  Whether you need to file a tax return depends on a few factors. In most cases, the amount of your income, your filing status and your age determine if you must file a tax return. For example, if you’re single and 28 years old you must file if your income was at least $10,150. Other rules may apply if you’re self-employed or if you’re a dependent of another person. There are also other cases when you must file. Go to IRS.gov/filing to find out if you need to file.

2. New for 2014: Premium Tax Credit.  If you bought health insurance through the Health Insurance Marketplace in 2014, you may be eligible for the new Premium Tax Credit. You will need to file a return to claim the credit. If you purchased coverage from the Marketplace in 2014 and chose to have advance payments of the premium tax credit sent directly to your insurer during the year you must file a federal tax return. You will reconcile any advance payments with the allowable Premium Tax Credit. You should receive Form 1095-A, Health Insurance Marketplace Statement, by early February. The new form will have information that will help you file your tax return.

3. Tax Withheld or Paid.  Did your employer withhold federal income tax from your pay? Did you make estimated tax payments? Did you overpay last year and have it applied to this year’s tax? If you answered “yes” to any of these questions, you could be due a refund. But you have to file a tax return to get it.

4. Earned Income Tax Credit.  Did you work and earn less than $52,427 last year? You could receive EITC as a tax refund if you qualify with or without a qualifying child. You may be eligible for up to $6,143. Use the 2014 EITC Assistant tool on IRS.gov to find out if you qualify. If you do, file a tax return to claim it.

5. Additional Child Tax Credit.  Do you have at least one child that qualifies for the Child Tax Credit? If you don’t get the full credit amount, you may qualify for the Additional Child Tax Credit.

6. American Opportunity Credit.  The AOTC is available for four years of post secondary education and can be up to $2,500 per eligible student.  You or your dependent must have been a student enrolled at least half time for at least one academic period. Even if you don’t owe any taxes, you still may qualify. However, you must complete Form 8863, Education Credits, and file a return to claim the credit. Use the Interactive Tax Assistant tool on IRS.gov to see if you can claim the credit. Learn more by visiting the IRS’ Education Credits Web page.

The instructions for Forms 1040, 1040A or 1040EZ list income tax filing requirements. You can also use the Interactive Tax Assistant tool on IRS.gov to see if you need to file. The tool is available 24/7 to answer many tax questions.

WASHINGTON—Refunds totaling more than $1 billion may be waiting for one million people who did not file a federal income tax return for 2008, the Internal Revenue Service announced today. However, to collect the money, a return for 2008 must be filed with the IRS no later than Tuesday, April 17, 2012.

The IRS estimates that half of these potential 2008 refunds are $637 or more.

Some people may not have filed because they had too little income to require filing a tax return even though they had taxes withheld from their wages or made quarterly estimated payments. In cases where a return was not filed, the law provides most taxpayers with a three-year window of opportunity for claiming a refund. If no return is filed to claim a refund within three years, the money becomes property of the U.S. Treasury.

For 2008 returns, the window closes on April 17, 2012. The law requires that the return be properly addressed, mailed and postmarked by that date. There is no penalty for filing a late return qualifying for a refund.

The IRS reminds taxpayers seeking a 2008 refund that their checks may be held if they have not filed tax returns for 2009 and 2010. In addition, the refund will be applied to any amounts still owed to the IRS, and may be used to offset unpaid child support or past due federal debts such as student loans.

By failing to file a return, people stand to lose more than refunds of taxes withheld or paid during 2008. Some people, especially those who did not receive an economic stimulus payment in 2008, may qualify for the Recovery Rebate Credit. In addition, many low-and moderate-income workers may not have claimed the Earned Income Tax Credit (EITC). The EITC helps individuals and families whose incomes are below certain thresholds. The thresholds for 2008 were:

$38,646 ($41,646 if married filing jointly) for those with two or more qualifying children, $33,995 ($36,995 if married filing jointly) for people with one qualifying child, and $12,880 ($15,880 if married filing jointly) for those with no qualifying children. For more information, visit the EITC Home Page on IRS.gov.

Current and prior year tax forms and instructions are available on the Forms and Publications page of IRS.gov or by calling toll-free 800-TAX-FORM (800-829-3676). Taxpayers who are missing Forms W-2, 1098, 1099 or 5498 for 2008, 2009 or 2010 should request copies from their employer, bank or other payer. If these efforts are unsuccessful, taxpayers can get a free transcript showing information from these year-end documents by ordering it on IRS.gov, filing Form 4506-T, or by calling 800-908-9946.

If you, your spouse or dependents had significant medical or dental costs in 2011, you may be able to deduct those expenses when you file your tax return. Here are eight things the IRS wants you to know about medical and dental expenses and other benefits.

1. You must itemize You deduct qualifying medical and dental expenses if you itemize on Form 1040, Schedule A.

2. Deduction is limited You can deduct total medical care expenses that exceed 7.5 percent of your adjusted gross income for the year. You figure this on Form 1040, Schedule A.

3. Expenses must have been paid in 2011 You can include the medical and dental expenses you paid during the year, regardless of when the services were provided. You’ll need to have good receipts or records to substantiate your expenses.

4. You can’t deduct reimbursed expenses Your total medical expenses for the year must be reduced by any reimbursement. Normally, it makes no difference if you receive the reimbursement or if it is paid directly to the doctor or hospital.

5. Whose expenses qualify You may include qualified medical expenses you pay for yourself, your spouse and your dependents. Some exceptions and special rules apply to divorced or separated parents, taxpayers with a multiple support agreement or those with a qualifying relative who is not your child.

6. Types of expenses that qualify You can deduct expenses primarily paid for the diagnosis, cure, mitigation, treatment or prevention of disease, or treatment affecting any structure or function of the body. For drugs, you can only deduct prescription medication and insulin. You can also include premiums for medical, dental and some long-term care insurance in your expenses. Starting in 2011, you can also include lactation supplies.

7. Transportation costs may qualify You may deduct transportation costs primarily for and essential to medical care that qualify as medical expenses. You can deduct the actual fare for a taxi, bus, train, plane or ambulance as well as tolls and parking fees. If you use your car for medical transportation, you can deduct actual out-of-pocket expenses such as gas and oil, or you can deduct the standard mileage rate for medical expenses, which is 19 cents per mile for 2011.

8. Tax-favored saving for medical expenses Distributions from Health Savings Accounts and withdrawals from Flexible Spending Arrangements may be tax free if used to pay qualified medical expenses including prescription medication and insulin.

For additional information, see Publication 502, Medical and Dental Expenses or Publication 969, Health Savings Accounts and Other Tax-Favored Health Plans, available at www.irs.gov or by calling 800-TAX-FORM (800-829-3676).

Determining your filing status is one of the first steps to filing your federal income tax return. There are five filing statuses: Single, Married Filing Jointly, Married Filing Separately, Head of Household and Qualifying Widow(er) with Dependent Child. Your filing status is used to determine your filing requirements, standard deduction, eligibility for certain credits and deductions, and your correct tax.Some people may qualify for more than one filing status. Here are eight facts about filing status that the IRS wants you to know so you can choose the best option for your situation.
1. Your marital status on the last day of the year determines your marital status for the entire year.
2. If more than one filing status applies to you, choose the one that gives you the lowest tax obligation.
3. Single filing status generally applies to anyone who is unmarried, divorced or legally separated according to state law.
4. A married couple may file a joint return together. The couple’s filing status would be Married Filing Jointly.
5. If your spouse died during the year and you did not remarry during 2011, usually you may still file a joint return with that spouse for the year of death.
6. A married couple may elect to file their returns separately. Each person’s filing status would generally be Married Filing Separately.
7. Head of Household generally applies to taxpayers who are unmarried. You must also have paid more than half the cost of maintaining a home for you and a qualifying person to qualify for this filing status.
8. You may be able to choose Qualifying Widow(er) with Dependent Child as your filing status if your spouse died during 2009 or 2010, you have a dependent child, have not remarried and you meet certain other conditions.
There’s much more information about determining your filing status in IRS Publication 501, Exemptions, Standard Deduction, and Filing Information. Publication 501 is available at www.irs.gov or by calling 800-TAX-FORM (800-829-3676). You can also use the Interactive Tax Assistant on the IRS website to determine your filing status. The ITA tool is a tax law resource on the IRS website that takes you through a series of questions and provides you with responses to tax law questions.

You are required to file a federal income tax return if your income is above a certain level, which varies depending on your filing status, age and the type of income you receive. However, the Internal Revenue Service reminds taxpayers that some people should file even if they aren’t required to because they may get a refund if they had taxes withheld or they may qualify for refundable credits.
To find out if you need to file, check the Individuals section of the IRS website at www.irs.gov or consult the instructions for Form 1040, 1040A or 1040EZ for specific details that may help you determine if you need to file a tax return with the IRS this year. You can also use the Interactive Tax Assistant available on the IRS website. The ITA tool is a tax law resource that takes you through a series of questions and provides you with responses to tax law questions.
Even if you don’t have to file for 2011, here are six reasons why you may want to:
1. Federal Income Tax Withheld You should file to get money back if your employer withheld federal income tax from your pay, you made estimated tax payments, or had a prior year overpayment applied to this year’s tax.
2. Earned Income Tax Credit You may qualify for EITC if you worked, but did not earn a lot of money. EITC is a refundable tax credit; which means you could qualify for a tax refund. To get the credit you must file a return and claim it.
3. Additional Child Tax Credit This refundable credit may be available if you have at least one qualifying child and you did not get the full amount of the Child Tax Credit.
4. American Opportunity Credit Students in their first four years of postsecondary education may qualify for as much as $2,500 through this credit. Forty percent of the credit is refundable so even those who owe no tax can get up to $1,000 of the credit as cash back for each eligible student.
5. Adoption Credit You may be able to claim a refundable tax credit for qualified expenses you paid to adopt an eligible child.
6. Health Coverage Tax Credit Certain individuals who are receiving Trade Adjustment Assistance, Reemployment Trade Adjustment Assistance, Alternative Trade Adjustment Assistance or pension benefit payments from the Pension Benefit Guaranty Corporation, may be eligible for a 2011 Health Coverage Tax Credit.
Eligible individuals can claim a significant portion of their payments made for qualified health insurance premiums.
