What financial records to keep and how long to keep them
You can't take everything with you, but there are some personal finance records you should keep. Here's a list of what those records are and how long you should keep them:

Record to keep
How long to keep it -- and why
Taxes
·         Returns
·         Canceled checks/receipts (alimony, charitable contributions, mortgage interest and retirement plan contributions)
Seven Years
·         The IRS has three years from your filing date to audit your return if it suspects good faith errors.
·         The three-year deadline also applies if you discover a mistake in your return and decide to file an amended return to claim a refund.
·         The IRS has six years to challenge your return if it thinks you underreported your gross income by 25 percent or more.
·         There is no time limit if you failed to file your return or filed a fraudulent return.
IRA contributions
Permanently
·         If you made a nondeductible contribution to an IRA, keep the records indefinitely to prove that you already paid tax on this money when the time comes to withdraw.
Retirement/Savings plan statements
From one year to permanently
·         Keep the quarterly statements from your 401(k) or other plans until you receive the annual summary; if everything matches up, then toss the quarterlies.
·         Keep the annual summaries until you retire or close the account.
Bank Records
From one year to permanently
·         Go through your checks each year and keep those related to your taxes, business expenses, housing and mortgage payments.
·         Throw away those that have no long-term importance.
Brokerage Statements
Until you sell the securities
·         You need the purchase/sales slips from your brokerage or mutual fund to prove whether you have capital gains or losses at tax time.
Bills
From one year to permanently
·         Go through your bills once a year.
·         In most cases, when the canceled check from a paid bill has been returned, you can get rid of the bill.
·         However, bills for big purchases -- such as jewelry, rugs, appliances, antiques, cars, collectibles, furniture, computers, etc. -- should be kept in an insurance file for proof of their value in the event of loss or damage.
Credit Card Receipts and Statements
From 45 days to seven years
·         Keep your original receipts until you get your monthly statement; toss the receipts if the two match up.
·         Keep the statements for seven years if tax-related expenses are documented.
Paycheck Stubs
One year
·         When you receive your annual W-2 form from your employer, make sure the information on your stubs matches
·         If it does, toss the stubs.
·         If it doesn't, demand a corrected form, known as a W-2c.
House/Condominium
From six years to permanently
·         Keep all records documenting the purchase price and the cost of all permanent improvements -- such as remodeling, additions and installations.
·         Keep records of expenses incurred in selling and buying the property, such as legal fees and your real estate agent's commission, for six years after you sell your home.
·         Holding on to these records is important because any improvements you make on your house, as well as expenses in selling it, are added to the original purchase price or cost basis. This adds up to a greater profit (also known as capital gains) when you sell your house. Therefore, you lower your capital gains tax.
