There are many reasons to keep records. In addition to tax purposes, you may need to keep records for insurance purposes or for getting a loan. Good records will help you:

• Identify sources of income. You may receive money or property from a variety of sources.
  Your records can identify the sources of your income. You need this information to separate
  business from nonbusiness income and taxable from nontaxable income.
• Keep track of expenses. You may forget an expense unless you record it when it occurs. You can use your records to identify expenses for which you can claim a deduction. This will help you determine if you can itemize deductions on your tax return.
  
• Keep track of the basis of property. You need to keep records that show the basis of your property. This includes the original cost or other basis of the property and any improvements you made.
  
• Prepare tax returns. You need records to prepare your tax return. Good records help you to file
  quickly and accurately.
• Support items reported on tax returns. You must keep records in case the IRS has a question about an item on your return. If the IRS examines your tax return, you may be asked to explain the items reported. Good records will help you explain any item and arrive at the correct tax with a minimum of effort. If you do not have records, you may have to spend time getting statements and receipts from various sources. If you cannot produce the correct documents, you may have to
  pay additional tax and be subject to penalties.

Income
Your basic records prove the amounts you report as income on your tax return. Your income may
include wages, dividends, interest, and partnership or S corporation distributions. Your records
also can prove that certain amounts are not taxable, such as tax-exempt interest. Note: If you receive a Form W-2, keep Copy C until you begin receiving social security benefits. This will help protect your benefits in case there is a question about your work record or earnings in a particular year. Review the information shown on your annual (for workers over age 25) Social Security Statement.

Expenses
Your basic records prove the expenses for which you claim a deduction (or credit) on your tax
return. Your deductions may include alimony, charitable contributions, mortgage interest, and real
estate taxes. You also may have child care expenses for which you can claim a credit.

Home
Your basic records should enable you to determine the basis or adjusted basis of your home. You
need this information to determine if you have a gain or loss when you sell your home or to figure
depreciation if you use part of your home for business purposes or for rent. Your records should
show the purchase price, settlement or closing costs, and the cost of any improvements. They also
may show any casualty losses deducted and insurance reimbursements for casualty losses. Your
records also should include a copy of Form 2119, Sale of Your Home, if you sold your previous home
before May 7, 1997, and postponed tax on the gain from that sale. When you sell your home, your records should show the sales price and any selling expenses, such as
commissions.

Investments
Your basic records should enable you to determine your basis in an investment and whether you have
a gain or loss when you sell it. Investments include stocks, bonds, and mutual funds. Your records
should show the purchase price, sales price, and commissions. They may also show any reinvested
dividends, stock splits and dividends, load charges, and original issue discount (OID).

One of your basic records is proof of payment. You should keep these records to support certain amounts shown on your tax return. Proof of payment alone is not proof that the item claimed on your return is allowable. You also should keep other documents that will help prove that the item is allowable. Generally, you prove payment with a cash receipt, financial account statement, credit card statement, canceled check, or substitute check. If you make payments in cash, you should get a dated and signed receipt showing the amount and the reason for the payment. If you make payments by electronic funds transfer, you may be able to prove payment with an account statement.

Alimony
If you receive or pay alimony, you should keep a copy of your written separation agreement or the divorce, separate maintenance, or support decree. If you pay alimony, you also will need to know your former spouse’s social security number.

Business Use of Your Home
You may be able to deduct certain expenses connected with the business use of your home. You should keep records that show the part of your home that you use for business and the expenses related to that use.

Casualty and Theft Losses
To deduct a casualty or theft loss, you must be able to prove that you had a casualty or theft. Your records also must be able to support the amount you claim.

 For a casualty loss, your records should show:

• The type of casualty (car accident, fire, storm, etc.) and when it occurred,
• That the loss was a direct result of the casualty, and
• That you were the owner of the property.

For a theft loss, your records should show:

• When you discovered your property was missing,
• That your property was stolen, and
• That you were the owner of the property.

Child Care Credit
You must give the name, address, and taxpayer identification number for all persons or organizations that provide care for your child or dependent. You can use Form W-10, Dependent Care Provider’sIdentification, and Certification, or various other sources to get the information from the care provider. Keep this information with your tax records.

Contributions
You must keep records to prove the contributions you make during the year. The kinds of records depend on whether the contribution is cash, noncash, or out-of-pocket expenses. For information on contributions and the records, you must keep, see Publication 526, Charitable Contributions.

Credit for the Elderly or the Disabled
If you are under age 65, you must have your physician complete a statement certifying that you were permanently and totally disabled on the date you retired.
You do not have to file this statement with your Form 1040 or Form 1040A, but you must keep it for your records.
If the Department of Veterans Affairs (VA) certifies that you are permanently and totally disabled, you can substitute VA Form 21-0172, Certification of Permanent and Total Disability, for the physician’s statement you are required to keep.

Education Expenses
If you have the records to prove your expenses, you may be entitled to claim certain tax benefits for your education expenses. You may qualify to exclude from income items such as a qualified scholarship, interest on U.S. savings bonds, or reimbursement from your employer. You also may qualify for certain credits or deductions. You should keep documents, such as transcripts or course descriptions, that show periods of enrollment and canceled checks and receipts that verify the amounts you spent on tuition, books, and other educational expenses.

Exemptions
If you are claiming an exemption for your spouse or a dependent (a qualifying child or a qualifying relative), you must keep records that support the deduction.
Employee Business Expenses
If you have employee business expenses, see Publication 463, Travel, Entertainment, Gift, and car expenses, for a discussion of what records to keep.
Energy Incentives

• The purchase price of the property, and
• That the property qualified for the credit.

  The following documents may show this information.
  

• Purchase and sales invoices.

Gambling Winnings and Losses
You must keep an accurate diary of your winnings and losses that includes the:

• Date and type of gambling activity,Name and address or location of the gambling establishment,

Medical and Dental Expenses
In addition to records you keep of regular medical expenses, you should keep records of transportation expenses that are primarily for and essential to medical care. You can record these expenses in a diary. You should record gas and oil expenses directly related to that transportation.
