1. Adjust your withholding Why wait another year for a big refund? Now is a good time to review your withholding and make adjustments for next year, especially if you'd prefer more money in each paycheck this year. If you owed at tax time, perhaps you'd like next year's tax payment to be smaller.

2. Store your return in a safe place Put your 2011 tax return and supporting documents somewhere secure so you'll know exactly where to find them if you receive an IRS notice and need to refer to your return. If it is easy to find, you can also use it as a helpful guide for next year's return.

3. Organize your recordkeeping Establish a central location where everyone in your household can put tax-related records all year long. Anything from a shoebox to a file cabinet works. Just be consistent to avoid a scramble for misplaced mileage logs or charity receipts come tax time.

4. Review your paycheck Make sure your employer is properly withholding and reporting retirement account contributions, health insurance payments, charitable payroll deductions and other items. These payroll adjustments can make a big difference on your bottom line. Fixing an error in your paycheck now gets you back on track before it becomes a huge hassle.

5. Shop for a tax professional early If you use a tax professional to help you strategize, plan and make financial decisions throughout the year, then search now. You'll have more time when you're not up against a deadline or anxious for your refund. Choose a tax professional wisely. You are ultimately responsible for the accuracy of your own return regardless of who prepares it.

6. Prepare to itemize deductions If your expenses typically fall just below the amount to make itemizing advantageous, a bit of planning to bundle deductions into 2012 may pay off. An early or extra mortgage payment, pre-deadline property tax payments, planned donations or strategically paid medical bills could equal some tax savings. See the Schedule A instructions for expenses you can deduct if you're itemizing and then prepare an approach that works best for you.

7. Strategize tuition payments The American Opportunity Tax Credit, which offsets higher education expenses, is set to expire after 2012. It may be beneficial to pay 2013 tuition in 2012 to take full advantage of this tax credit, up to $2,500, before it expires. For more information, see IRS Publication 970, Tax Benefits for Education.

The IRS sends millions of letters and notices to taxpayers for a variety of reasons. Many of these letters and notices can be dealt with simply, without having to call or visit an IRS office.

Here are eight things to know about IRS notices and letters.

1. There are a number of reasons why the IRS might send you a notice. Notices may request payment, notify you of account changes, or request additional information. A notice normally covers a very specific issue about your account or tax return.

2. Each letter and notice offers specific instructions on what action you need to take.

3. If you receive a correction notice, you should review the correspondence and compare it with the information on your return.

4. If you agree with the correction to your account, then usually no reply is necessary unless a payment is due or the notice directs otherwise.

5. If you do not agree with the correction the IRS made, it is important to respond as requested. You should send a written explanation of why you disagree and include any documents and information you want the IRS to consider along with the bottom tear-off portion of the notice. Mail the information to the IRS address shown in the upper left of the notice. Allow at least 30 days for a response.

6. Most correspondence can be handled without calling or visiting an IRS office. However, if you have questions, call the telephone number in the upper right of the notice. Have a copy of your tax return and the correspondence available when you call to help the IRS respond to your inquiry.

7. It’s important to keep copies of any correspondence with your records.

8. IRS notices and letters are sent by mail. The IRS does not correspond by email about taxpayer accounts or tax returns.

If you discover an error on your federal income tax return after you e-filed or mailed it, you may want or need to amend your return. Perhaps you are eligible for a deduction or credit and you missed it the first time?

Here are eight key points the IRS wants you to know about when considering whether to file an amended federal income tax return.

1. Use Form 1040X, Amended U.S. Individual Income Tax Return, to file an amended income tax return.

2. Use Form 1040X to correct previously filed Forms 1040, 1040A or 1040EZ. An amended return cannot be e-filed; you must file it by paper.

3. Generally, you do not need to file an amended return to correct math errors. The IRS will automatically make that correction. Also, do not file an amended return because you forgot to attach tax forms such as W-2s or schedules. The IRS normally will send a request asking for those.

4. Be sure to enter the year of the return you are amending at the top of Form 1040X. Generally, you must file Form 1040X within three years from the date you filed your original return or within two years from the date you paid the tax, whichever is later.

5. If you are amending more than one tax return, prepare a 1040X for each return and mail them in separate envelopes to the appropriate IRS campus. The 1040X instructions list the addresses for the campuses.

6. If the changes involve another schedule or form, you must attach that schedule or form to the amended return.

7. If you are filing to claim an additional refund, wait until you have received your original refund before filing Form 1040X. You may cash that check while waiting for any additional refund.

8. If you owe additional 2011 tax, file Form 1040X and pay the tax before the due date to limit interest and penalty charges that could accrue on your account. Interest is charged on any tax not paid by the due date of the original return, without regard to extensions.

. 1. Normally, tax records should be kept for three years.

2. Some documents — such as records relating to a home purchase or sale, stock transactions, IRA and business or rental property — should be kept longer.

3. n most cases, the IRS does not require you to keep records in any special manner. Generally speaking, however, you should keep any and all documents that may have an impact on your federal tax return.

4. Records you should keep include bills, credit card and other receipts, invoices, mileage logs, canceled, imaged or substitute checks, proofs of payment, and any other records to support deductions or credits you claim on your return.

You may need to pay estimated taxes to the IRS during the year if you have income that is not subject to withholding. This depends on what you do for a living and the types of income you receive.

1. If you have income from sources such as self-employment, interest, dividends, alimony, rent, gains from the sales of assets, prizes or awards, then you may have to pay estimated tax.

2. As a general rule, you must pay estimated taxes in 2012 if both of these statements apply: 1) You expect to owe at least $1,000 in tax after subtracting your tax withholding (if you have any) and tax credits, and 2) You expect your withholding and credits to be less than the smaller of 90 percent of your 2012 taxes or 100 percent of the tax on your 2011 return. Special rules apply for farmers, fishermen, certain household employers and certain higher income taxpayers.

3. For Sole Proprietors, Partners and S Corporation shareholders, you generally have to make estimated tax payments if you expect to owe $1,000 or more in tax when you file your return.

4. To figure your estimated tax, include your expected gross income, taxable income, taxes, deductions and credits for the year. Use the worksheet in Form 1040-ES, Estimated Tax for Individuals, for this. You want to be as accurate as possible to avoid penalties. Also, consider changes in your situation and recent tax law changes.

5. The year is divided into four payment periods, or due dates, for estimated tax purposes. Those dates generally are April 15, June 15, Sept. 15 and Jan. 15 of the next or following year.

6. Form 1040-ES, Estimated Tax for Individuals, has everything you need to pay estimated taxes. It includes instructions, worksheets, schedules and payment vouchers

Tax-filing extensions are available to taxpayers who need more time to finish their returns. Remember, this is an extension of time to file; not an extension of time to pay. However, taxpayers who are having trouble paying what they owe usually qualify for payment plans and other relief. Last month, for example, the IRS, as part of its Fresh Start initiative announced penalty relief for unemployed taxpayers and self-employed individuals whose income has dropped.

Either way, taxpayers will avoid stiff penalties if they file either a regular income tax return or a request for a tax-filing extension by this year’s April 17 deadline. Taxpayers should file, even if they can’t pay the full amount due.

Here are further details on the options available.

More Time to File

People who haven’t finished filling out their return can get an automatic six-month extension. The fastest and easiest way to get the extra time is through the Free File link on IRS.gov . In a matter of minutes, anyone, regardless of income, can use this free service to electronically request an automatic tax-filing extension on Form 4868.

Filing this form gives taxpayers until Oct. 15 to file a return. To get the extension, taxpayers must estimate their tax liability on this form and should also pay any amount due.

By properly filing this form, a taxpayer will avoid the late-filing penalty, normally five percent per month based on the unpaid balance, that applies to returns filed after the deadline. In addition, any payment made with an extension request will reduce or eliminate interest and late-payment penalties that apply to payments made after April 17. The current interest rate three percent per year, compounded daily, and the late-payment penalty is normally 0.5 percent per month.

Some taxpayers get more time to file without having to ask for it. These include:

• Taxpayers abroad. U.S. citizens and resident aliens who live and work abroad, as well as members of the military on duty outside the U.S., have until June 15 to file. Tax payments are still due April 17.

• Members of the military and others serving in Iraq, Afghanistan or other combat zone localities. Typically, taxpayers can wait until at least 180 days after they leave the combat zone to file returns and pay any taxes due.

• People affected by certain tornadoes, severe storms, floods and other recent natural disasters. Currently, parts of Indiana, Kentucky, Tennessee and West Virginia are covered by federal disaster declarations, and affected individuals and businesses in these areas have until May 31 to file and pay.

More Time to Pay

Taxpayers who have finished their returns should file by the regular April 17 deadline, even if they can’t pay the full amount due. In many cases, those struggling with unpaid taxes qualify for one of several relief programs, including those recently expanded under the IRS "Fresh Start" initiative. These include the following:

• Most people can set up a payment agreement with the IRS on line in a matter of minutes. Those who owe $50,000 or less in combined tax, penalties and interest can use the Online Payment Agreement to set up a monthly payment agreement for up to six years. Taxpayers can choose this option even if they have not yet received a bill or notice from the IRS. Alternatively, taxpayers can request a payment agreement by filing Form 9465-FS. This form can be downloaded from IRS.gov and mailed along with a tax return, bill or notice.

• Most unemployed filers and self-employed individuals whose business income dropped substantially can apply for a six-month extension of time to pay. Eligible taxpayers will not be charged a late-payment penalty if they pay any tax, penalty and interest due by Oct. 15, 2012. Taxpayers qualify if they were unemployed for any 30-day period between Jan. 1, 2011 and April 17, 2012. Self-employed people qualify if their business income declined 25 percent or more in 2011, due to the economy. Income limits and other special rules apply. Apply using Form 1127-A.

• Some struggling taxpayers may qualify for an offer-in-compromise. This is an agreement between a taxpayer and the IRS that settles the taxpayer’s tax liabilities for less than the full amount owed. Generally, an offer will not be accepted if the IRS believes the liability can be paid in full as a lump sum or through a payment agreement. The IRS looks at the taxpayer’s income and assets to make a determination regarding the taxpayer’s ability to pay.

If you owe tax with your federal tax return, but can't afford to pay it all when you file, here are five tips:

1. File your return on time and pay as much as you can with the return. These steps will eliminate the late filing penalty, reduce the late payment penalty and cut down on interest charges. For electronic and credit card options for paying see IRS.gov. You may also mail a check payable to the United States Treasury

2. Consider obtaining a loan or paying by credit card. The interest rate and fees charged by a bank or credit card company may be lower than interest and penalties imposed by the Internal Revenue Code.

3. Request an installment payment agreement. You do not need to wait for IRS to send you a bill before requesting a payment agreement. Options for requesting an agreement include:
• Completing and submitting IRS Form 9465-FS, Installment Agreement Request, with your return
4. Request an extension of time to pay. For tax year 2011, qualifying individuals may request an extension of time to pay and have the late payment penalty waived as part of the IRS Fresh Start Initiative. But hurry, your application must be filed by April 17, 2012.

5. If you receive a bill from the IRS, contact them immediately to discuss these and other payment options. Ignoring the bill will only compound your problem and could lead to IRS collection action.

If you can’t pay in full and on time, the key to minimizing your penalty and interest charges is to pay as much as possible by the tax deadline and the balance as soon as you can.

You have two extra days this year to make contributions to your Individual Retirement Arrangements. That’s because April 15 falls on a weekend and Emancipation Day, a legal holiday in the District of Columbia, will be observed on Monday, April 16. That means the due date for filing your tax return and making contributions to your 2011 IRA is Tuesday, April 17.

1. You may be able to deduct some or all of your contributions to your IRA. You may also be eligible for the Savers Credit, formally known as the Retirement Savings Contributions Credit.

2. Contributions can be made to your traditional IRA at any time during the year or by the due date for filing your return for that year, not including extensions. For most people, this means you must make contributions for 2011 by April 17, 2012. If you contribute between Jan. 1 and April 17, you should designate the year targeted for the contribution.

3. The funds in your IRA are generally not taxed until you receive distributions from it.

4. Use the worksheets in the instructions for either Form 1040A or Form 1040 to figure your deduction for your IRA contributions.

5. For 2011, the most you can contribute to your traditional IRA is generally the smaller of the following amounts: $5,000 for most taxpayers, $6,000 for taxpayers who were 50 or older at the end of 2011 or the amount of your taxable compensation for the year.

6. Use Form 8880, Credit for Qualified Retirement Savings Contributions, to determine whether you are also eligible for a tax credit equal to a percentage of your contribution.

7. You must use either Form 1040A or Form 1040 to deduct your IRA contribution or claim the Credit for Qualified Retirement Savings Contributions.

8. You must be under age 70 1/2 at the end of the tax year in order to contribute to a traditional IRA.

You may be an injured spouse if you file a joint tax return and all or part of your portion of a refund was, or is expected to be, applied to your spouse’s legally enforceable past due financial obligations.

Here are seven facts about claiming injured spouse relief:

1. To be considered an injured spouse; you must have paid federal income tax or claimed a refundable tax credit, such as the Earned Income Credit or Additional Child Tax Credit on the joint return, and not be legally obligated to pay the past-due debt.

2. Special rules apply in community property states.

3. If you filed a joint return and you're not responsible for the debt, but you are entitled to a portion of the refund, you may request your portion of the refund by filing Form 8379, Injured Spouse Allocation.

4. You may file form 8379 along with your original tax return or your may file it by itself after you receive an IRS notice about the offset.

5. You can file Form 8379 electronically. If you file a paper tax return you can include Form 8379 with your return, write "INJURED SPOUSE" at the top left of the Form 1040, 1040A or 1040EZ. IRS will process your allocation request before an offset occurs.

6. If you are filing Form 8379 by itself, it must show both spouses' Social Security numbers in the same order as they appeared on your income tax return. You, the "injured" spouse, must sign the form.

7. Do not use Form 8379 if you are claiming innocent spouse relief. Instead, file Form 8857, Request for Innocent Spouse Relief. This relief from a joint liability applies only in certain limited circumstances. However, in 2011 the IRS eliminated the two-year time limit that applies to certain relief requests.

Past due financial obligations can affect your current federal tax refund. The Department of Treasury's Financial Management Service, which issues IRS tax refunds, can use part or all of your federal tax refund to satisfy certain unpaid debts.

Here are eight important facts the IRS wants you to know about tax refund offsets:

1. If you owe federal or state income taxes, your refund will be offset to pay those taxes. If you had other debt such as child support or student loan debt that was submitted for offset, FMS will apply as much of your refund as is needed to pay off the debt and then issue any remaining refund to you.

2. You will receive a notice if an offset occurs. The notice will include the original refund amount, your offset amount, the agency receiving the payment and its contact information.

3. If you believe you do not owe the debt or you are disputing the amount taken from your refund, you should contact the agency shown on the notice, not the IRS.

4. If you filed a joint return and you're not responsible for the debt, but you are entitled to a portion of the refund, you may request your portion of the refund by filing IRS Form 8379, Injured Spouse Allocation. Attach Form 8379 to your original Form 1040, Form 1040A, or Form 1040EZ or file it by itself after you are notified of an offset.

5. You can file Form 8379 electronically. If you file a paper tax return you can include Form 8379 with your return, write "INJURED SPOUSE" at the top left of the Form 1040, 1040A or 1040EZ. IRS will process your allocation request before an offset occurs.

6. If you are filing Form 8379 by itself, it must show both spouses' Social Security numbers in the same order as they appeared on your income tax return. You, the "injured" spouse, must sign the form. Do not attach the previously filed Form 1040 to the Form 8379. Send Form 8379 to the IRS Service Center where you filed your original return.

7. The IRS will compute the injured spouse's share of the joint return. Contact the IRS only if your original refund amount shown on the FMS offset notice differs from the refund amount shown on your tax return.

8. Follow the instructions on Form 8379 carefully and be sure to attach the required forms to avoid delays.
