Why shred?

“Dumpster diving,” or rifling through trash cans for personal information, is a tactic used by identity thieves. You are taking a terrible risk if you don’t shred sensitive material.

Invest in a shredder for your home or office, preferably one that “cross cuts” (slices in two directions), and destroy all sensitive information including bank and credit card statements you no longer need, carbon-copy charge receipts with your account information, insurance forms, physician bills, etc. If your shredder can’t handle plastic, use scissors to cut up expired credit and identification cards before discarding them.

For larger jobs, consider hiring a commercial shredding company.

What should I shred?

In short, destroy all sensitive information including junk mail and paperwork that includes:

  • Account numbers
  • Birth dates
  • Passwords and PINs
  • Signatures
  • Social Security numbers

To protect your privacy, you should also consider shredding items that include:

  • Names
  • Addresses
  • Phone numbers
  • E-mail addresses

How long should I keep sensitive documents?

When sorting through dusty file boxes or the pile of papers on your desk, it’s easy to become confused as to which records you need to keep and those you should shred. Here are some guidelines to help you determine how long to keep records:

  • Tax Records:  Seven years, to be safe. The IRS has three years to audit your return if the agency suspects you made a mistake and up to six years if you likely underreported your gross income by 25 percent or more. If you failed to file a return for any year, keep records indefinitely.
  • Pay Stubs:  One year. Match them up to your W2 form, then shred.
  • Bank Statements:  One year. But hold onto records related to your taxes, business expenses, home improvements, mortgage payments and major purchases for as long as you need them. Many financial institutions now provide the option to receive your bank and credit statements online instead of by mail.
  • Credit Card Statements:  At least 45 days. The rules here are similar to those for bank statements; hang on to those you may need for your taxes or as proof of purchase. Shred the rest after you’ve confirmed payment.
  • Medical Records:  At least a year, but often longer. Keep medical bills for at least a year in case of a dispute over a reimbursement. Some experts suggest keeping other records for five years from the time treatment for the symptoms ended. Hang on to information about prescription information, specific medical histories, health insurance information and contact information for your physician.
  • Insurance Records:  Keep policy information for the life of the policy plus an additional five years. Additional records such as statements, hospital bills, car repair bills, copies of prescriptions, etc. should be kept up to five years from the date the service was provided.
    Utility and phone bills:  Shred them after you’ve paid them, unless they contain tax-deductible expenses.
  • IRA Contributions:  Until you withdraw the money. You can shred quarterly statements as soon as you match them with your yearly statement.
  • Home Purchase/Sale/Improvements:  Until six years after you sell. Improvements you make and expenses such as your real estate agent’s commission are factored in when you sell your home, lowering your capital gains tax.
  • Warranties:  As long as they are current. Expired warranties can be recycled, unless they contain personal information.

Can I recycle shredded paper?

That depends. According to the City of Seattle's website, confetti-like pieces from cross-cut shredders have no retrievable fibers for recycling. Cross-cut shredded paper can be added to yard waste carts or compost. Other sources indicate that shredded paper can be recycled if its bundled, so check with your waste service provider.

Here are some suggesting for re-using shredded paper: Substitute for tissue paper in gift bags or baskets, ship fragile items, line your hamster's cage, add it to a worm composting bin, kids' art projects, such as stuffing pillows or bean bags.

Some commercial shredders pulverize paper. Others cross-shred. Many commercial shredders transport the destroyed documents to a recycling center to be used as paper or other products. Check with individual companies per their procedures.

  • Address labels from junk mail and magazines

  • Insurance documents
  • Investment, stock and property transactions
