Want to rest assured you have all the documents you need when you need them, but not be awash in paper? Read on.
Unless you’re living in the 123-room Spelling Manor, you probably don’t have space to store massive amounts of tax and insurance paperwork, warranties, and repair receipts related to your home. But you’ll definitely want your paperwork at hand if you have to prove you deserved a tax deduction, file an insurance claim, or figure out if your busted oven is still under warranty.
Except for tax paperwork, there’s no official guideline governing exactly how long you have to keep most home-related documents. Lucky for you, we considered the situations in which you might need documents and came up with a handy “How Long to Keep It” home records checklist.

First, a little background on IRS rules, which informed some of our charts:
  • The IRS says you should keep tax returns and the paperwork supporting them for at least three years after you file the return -- the amount of time the IRS has to audit you. So that’s how long we advise in our charts.
  • Check with your state about state income tax, though. Some make you keep tax records a really long time: In Ohio, it’s 10 years.
  • The IRS can also ask for records up to six years after a filing if they suspect someone failed to report 25% or more of his gross income. And the agency never closes the door on an audit if it suspects fraud. Just sayin'.
HOME SALE RECORDS
DocumentHow Long to Keep It
Home sale closing documents, including HUD-1 settlement sheetAs long as you own the property + 3 years
Deed to the houseAs long as you own the property
Builder's warranty or service contract for new homeUntil the warranty period ends
Community/condo association covenants, codes, restrictions (CC&Rs)As long as you own the property
Receipts for capital improvementsAs long as you own the property + 3 years
Section 1031 (like-kind exchange) sale records for both your old and new properties, including HUD-1 settlement sheetAs long as you own the property + 3 years
Mortgage payoff statements (certificate of satisfaction or lien release)Forever, just in case a lender says, "Hey, you still owe money."
Why you need these docs: You use home sale closing documents, receipts for capital improvements, and like-kind exchange records to calculate and document your profit (gain) when you sell your home. Your deed and mortgage payoff statements prove you own your home and have paid off your mortgage, respectively. Your builder’s warranty or contract is important if you file a claim. And sooner or later you’ll need to check the CC&R rules in your condo or community association.

Organizing Your Home Records

Because paper, such as receipts, fades with time and takes up space, consider scanning and storing your documents on a flash drive, an external hard drive, or a cloud-based remote server. Even better, save your documents to at least two of these places.

Digital copies are OK with the IRS as long as they’re identical to the originals and contain all the accurate information that was in the original receipts. You must be able to produce a hard copy if the IRS asks for one.

Tip: Tax season and year’s end are good times to purge files and toss what you no longer need; that's often when the spirit of organization moves us.

When you do finally toss out your home-related paperwork, use a shredder. Throwing away intact documents with personal financial information puts you at risk for identity theft.
