Bills, credit-card receipts, ATM slips, investment records, bank statements -- they pile up and multiply faster than dirty dishes after a holiday meal. It's easy to feel buried under an avalanche of paper and too stressed and guilty to deal with it.

Fortunately, there are solutions short of hiring a full-time financial manager. Getting clear of the paper chaos will save time (no more scrambling through drawers to find that overdue bill), -money (fewer late charges and no lost deductions), and psychic energy (no more feeling out of control of your own financial life).

The experts say you can organize your records in five simple steps. Here's what they recommend:

Step #1: Toss what you can.
Nearly all of your financial papers can be divided into three categories: records that you need to keep only for the calendar year or less, papers that you need to save for seven years (the typical window during which your tax return may be audited), and papers that you should hang onto indefinitely.

For instance, do you really need to save all those ATM-withdrawal receipts? No. Once you've recorded the amount you've withdrawn in your check register and reconciled the information as it appears on your monthly statement, you can throw away the ATM slip. The same holds true for deposit slips and credit-card receipts, once you've checked to make sure the items you bought appear correctly on your statement. Don't keep sales receipts for minor purchases after you've satisfactorily used the item a few times or the warranty has expired. Keep receipts for major purchases (any item whose replacement cost exceeds the deductible on your homeowners' or renters' insurance).

Shortly after the end of the calendar year, you will probably be able to throw out a slew of additional paper, including your paycheck stubs, monthly credit-card and mortgage statements, utility bills (if they are not needed for business deductions), and monthly or quarterly reports from brokerage and mutual-fund companies for the previous year.

"Typically the entire year's activity is listed in detail on your final, end-of-the-year statement, making every other statement redundant," says Ed Slott, a CPA in Rockville Center, New York. Your final pay stub and W-2 form, for instance, document all your earnings for the year if you work for someone else; if you're self-employed, your 1099 forms do the same for you. Similarly, most investment companies and some credit-card issuers send out comprehensive statements in January. "Keep the monthly updates until you reconcile them with the year-end summaries," says Slott.

Step #2: Hang onto what you must.
You will, however, need to hold onto those final credit-card statements, along with your W-2s and 1099s, for at least three years and, preferably, for seven. The Internal Revenue Service has up to three years from the date you file your tax return to examine it for errors and as long as six years to conduct an audit if there's reason to suspect you underreported your gross income by 25 percent or more. (There is no statute of limitations for anyone who has deliberately committed fraud.) Indeed, you'll need to keep any paperwork that supports your return until that audit window closes. Among the additional documents you should retain: canceled checks and receipts for all deductible business expenses (such as those for entertainment, home-office equipment, and professional dues), retirement-account contributions, charitable donations, child-care bills, out-of-pocket medical expenses, alimony, and mortgage-interest and property-tax payments.

Unless you've knowingly submitted a false return, you can toss these supporting documents after three to seven years, depending on how straightforward your tax situation is.

But don't throw out the actual tax returns or the year-end summaries of your investment accounts, even after the chances of an audit have all but vanished. These documents don't take up much space and can come in very handy for future financial planning.

For insurance purposes, you'll also want to keep receipts for major purchases and receipts that show how much you've paid for home improvements indefinitely, both to satisfy potential buyers and to reduce possible capital-gains taxes when you sell your home. True, these records are not as important as they once were because of recent changes in the law that exempt from taxation the first $500,000 in profits from the sale of a home ($250,000 for singles), but they may still come in handy. It is crucially important to keep the confirmation slips that show beneficiary designations and the purchase price of stocks, mutual funds, and any other investments you hold; hang onto these records indefinitely because some day, says Slott, "you or your heirs will have to know exactly how much you paid to determine the profit on your investment for tax purposes."
