Keep or Shred? A Paper-Sorting Plan for Downsizers, With the IRS Retention Rules

Before a move, sort paper into three piles: keep permanently, keep for a set time, and shred. The IRS says to keep records that support a tax return until the period of limitations expires, usually three years. Home purchase and improvement records stay until that period ends for the year you sell.

Paper is the part of downsizing that people put off, and it is the part that can hurt if you get it wrong. This guide is for anyone about to move who has filing cabinets, shoeboxes and a drawer of unopened mail. It gives you a short plan, the IRS retention rules in plain words, and a way to dispose of the rest safely. Midlife Simplicity breaks a move into small, ordered jobs, and paper belongs near the start.

Why paper should come first

Paper is heavy, and it hides risk. A box of old statements can weigh thirty pounds and carry account numbers, your birth date and your Social Security number. Movers pack it, a storage unit holds it, and nobody checks it.

The federal government's guide to identity theft warns that scammers may go through trash for bank statements or tax documents. It also advises you to keep your Social Security card in a safe place instead of your wallet. A move is a good time to apply both ideas.

Sorting early also saves money. Fewer boxes mean a smaller moving quote and a smaller storage unit. And you want to know where your deed, insurance papers and tax returns are before the van leaves, not after.

How long should you keep tax records?

Keep records that support any income, deduction or credit on a return until the period of limitations for that return expires. That is the Internal Revenue Service (IRS) rule. The agency's page on how long to keep records lists the main periods in the table below.

The IRS adds one more note. Before you discard records that you no longer need for tax purposes, check whether insurers or creditors want you to keep them longer. A loan agreement may have its own rule.

Many people keep seven years of returns to be safe. That is a common habit, not an IRS rule. If you pick a number, write it on the folder so you are not guessing later.

Which home records should you never throw out?

Keep the records of your home until well after you sell it. The IRS says to keep property records until the period of limitations ends for the year you dispose of the property. You need them to work out gain or loss.

That means your closing statement from the purchase, receipts for big improvements such as a new roof or kitchen, and the closing statement from the sale. Together they let you prove your basis, which is what you paid plus improvements. Our guide to capital gains tax when selling the family home shows why that number matters.

If you sell this year, keep these papers until the limitation period for the sale year ends. Scan them as well. A scan in two places is better than a paper file in a box that goes missing.

The three-pile method

A good sorting method is simple and kind. Use short sessions of 30 to 45 minutes, one category at a time, with three piles on the table:

Do not sort by room. Sort by category, starting with the easy ones. Old magazines and expired warranties build momentum. Medical and legal papers can wait for a clear head.

What to keep permanently

These are our editorial suggestions, not legal rules. Keep them in one fireproof box or a bag you carry yourself in the move:

If you have a deed to update, see our explainer on transfer-on-death deeds in 2026, since a new deed may change which papers you need to hold.

Medical, insurance and benefit papers

These are the papers people shred too fast. Keep current insurance policies, the latest statement from each retirement account and any paperwork about a claim that is still open. Keep a list of your doctors, medicines and policy numbers where a family member can find it.

Old explanation-of-benefits statements are different. Once you have matched them to your bills and no claim is open, most can go. If you deduct medical costs on a return, keep the proof with that year's tax file until the retention period ends.

When in doubt, hold a paper for one more season. The cost of keeping one folder is small. The cost of needing a proof you shredded can be large.

What can you shred, and how?

Shred statements and bills you no longer need once their retention period passes. That includes old bank and credit card statements, pay stubs after you match them to a yearly form, and expired insurance policies. Check the list first for anything tied to a tax return or a dispute.

Use a cross-cut shredder at home, or take paper to a community shredding event or a trusted service. Do not put intact statements in the recycling bin. Shredding takes longer than people expect, so spread it over several evenings.

If you need old returns later, you may not need the paper at all. The IRS says you can get tax return transcripts online or by mail, and a transcript shows most line items from your return. Its page on getting a tax transcript explains the steps. Mailed transcripts take 5 to 10 calendar days to reach the address the IRS has on file.

Label each pile with a sticky note that says what it is and, for timed papers, the year you can discard it. A labeled box is easy to hand to a family member, an accountant or an executor, and it saves them guessing after you have moved.

Scan before you shred

Scanning cuts the amount of paper you carry, and a good scan can stand in for most old records. Use your phone or a flatbed scanner. Name each file with the year and type, such as "2024 property tax bill," and save it in a folder for each category.

Back up the folder to a second place, such as an external drive and a secure cloud account. Then check that a few random files open. Only then shred the paper. Keep originals of anything where the paper itself matters, such as certificates and signed documents.

Protect the digital copies too. Use a strong password and two-step sign-in, and do not email scans of your Social Security card.

Fitting paper into your move timeline

Start sorting about ten weeks before the move date. Our ten-week winter move countdown shows where it fits. Do paper in the first three weeks, because the choices are quick and the shredding takes time.

Make a "moving binder" for the final weeks. Put in your lease or closing documents, mover contracts and a list of who to tell about your new address. Our change-of-address checklist covers that list. Carry the binder yourself, never in the van.

What we cannot decide for you

Retention needs vary. Business owners, landlords and people with disputes may need to keep records longer. State agencies and lenders can have their own rules. This is general information, not tax or legal advice. Reviewed by the Midlife Simplicity editorial team on October 26, 2026. If you are unsure about a record, keep it and ask a tax preparer.

Conclusion

A paper-sorting plan makes a move lighter and safer. Keep what proves who you are and what you own, hold tax and home records for their set periods, and shred the rest. Scan first, and back up the scans.

Your next step is one 30-minute session. Pick a single drawer, make the three piles and put the keep-permanently pile in a box you will carry yourself.
