What records storage is and why businesses use it

Records storage is space—either in your own building, a rented facility, or the cloud—where you keep documents your business needs to keep but doesn't use every day. This includes tax returns, contracts, employee files, invoices, customer receipts, and legal paperwork. Most businesses store records because they have to: tax authorities, employment law, and industry regulators all require you to hold onto certain documents for a set number of years.

The choice between storing records yourself and paying a storage company matters because it affects how fast you can find something if you're audited, sued, or need to prove you followed the rules. It also affects your costs, security, and how much space your office takes up. A small business might keep everything in a filing cabinet. A larger one might rent a climate-controlled warehouse or use a digital service that stores scans of documents online.

Key Takeaways

  • Different types of records have different legal holding periods—tax documents usually three to seven years, employee records typically three years after someone leaves, and contracts often as long as the agreement lasts plus several years after.
  • Physical storage requires you to organize documents, protect them from fire and water damage, and control who can access them; digital storage does this automatically but costs money each month.
  • The IRS and state tax agencies can request records during an audit, so you need a system that lets you find specific documents quickly.
  • Destroying records before the legal holding period ends can result in fines and legal trouble, so a written retention schedule prevents accidental disposal.

How long you have to keep different types of records

The holding period depends on what the document is and which agency regulates it. The IRS generally requires you to keep tax records—including receipts, invoices, and bank statements—for at least three years from the date you file your return. If you underreport income by more than 25 percent, the IRS can go back six years. Some states require longer periods for sales tax records.

Employee records must be kept for at least three years after an employee leaves, according to the Fair Labor Standards Act. This includes time sheets, payroll records, and hiring documents. If you have a workplace injury, OSHA requires you to keep injury and illness records for five years. Contracts and agreements should be kept for the length of the contract plus at least three to five years after it ends, depending on the type of contract and your industry.

If you're in a regulated industry—healthcare, finance, construction—your holding periods may be longer. A doctor's office might keep patient records for seven years after the last visit. A bank keeps loan documents for seven years. Check with your industry association or a business accountant to confirm what applies to you, because penalties for destroying records too early can be steep.

Physical storage: filing cabinets, on-site, and off-site facilities

The simplest option is to store records in your own office—filing cabinets, shelves, or a locked closet. This costs nothing beyond the furniture and keeps documents within arm's reach. The downside is that it takes up space, and your documents are only as safe as your building. A fire, flood, or break-in puts everything at risk. You also have to organize the system yourself and make sure only authorized people can access sensitive files.

If you run out of space or want better protection, you can rent a storage unit from a commercial records storage company. These facilities are climate-controlled, fireproof, and staffed. You box up your documents, the company stores them, and you can request specific boxes when you need them—usually within 24 hours. The company charges a monthly fee based on how many boxes you store. This works well for documents you rarely need but must keep.

The trade-off is speed and cost. Retrieving a box takes a day or two, not minutes. Monthly fees add up—a small business might pay $50 to $200 a month depending on volume. You also have to trust the company with sensitive information, so check whether they're bonded and insured, and ask about their security practices and data destruction procedures when you're done with the records.

Digital storage and document scanning

Digital storage means scanning paper documents into a computer system and storing the files in the cloud or on a find server. You can search by keyword, retrieve a document in seconds, and access it from anywhere. Many services include automatic backup, so if your office burns down, your records still exist. You can also set permissions so only certain employees see certain files.

The costs vary widely. Some services charge per document scanned, others charge a monthly subscription based on storage size. A small business might pay $30 to $100 a month; larger operations pay more. You can scan documents yourself using a regular scanner and free software, or hire the storage company to pick up boxes and scan them for you—that costs extra but saves time.

The catch is that digital records have their own legal requirements. The IRS accepts digital copies of tax records only if they're clear, complete, and stored in a format that won't disappear (not a proprietary format that only one company uses). You also need to keep the original paper for a set period in some cases, depending on the document type and your industry. Ask your accountant or a records management consultant whether you can destroy the paper originals after scanning, or whether you need to keep both.

How to organize a records retention schedule

A retention schedule is a written list that says what documents you keep, for how long, and when you destroy them. It prevents someone from accidentally throwing away a contract that's still legally required, and it shows regulators that you have a system in place. You don't need a fancy template—a spreadsheet works fine.

Start by listing the types of documents your business creates: tax returns, invoices, employee files, contracts, customer records, and so on. For each type, write down the legal holding period (check with your accountant or industry regulator). Then decide whether you'll keep the original paper, scan it and destroy the paper, or keep both. Set a date each year when you review what can be destroyed—many businesses do this in January or after tax season.

Once you have a schedule, follow it. Don't keep documents longer than necessary just to be safe—that wastes space and money. But don't destroy them early, either. If you're ever audited or sued, the first thing lawyers ask for is your retention schedule. If you don't have one, it looks like you're making decisions on the fly, which raises suspicion. If you have one and followed it, you're protected.

Security and access control

Records contain sensitive information: employee Social Security numbers, customer payment details, contract terms, and financial data. Whoever stores your records—you, a storage company, or a cloud service—needs to protect them from theft, unauthorized access, and accidental disclosure.

If you store records on-site, keep them in a locked cabinet or room. Limit who has keys or passwords. If you use a storage company, ask whether they have surveillance cameras, alarm systems, and background checks for staff. Ask what happens if someone requests a document—do they verify the request is legitimate? If you use digital storage, choose a service that encrypts files, requires strong passwords, and logs who accesses what and when. Check whether the company has a privacy policy and whether they sell or share your data.

You also need a plan for destroying records securely when the retention period ends. Paper documents should be shredded, not thrown in the trash. Digital files should be permanently deleted, not just moved to a trash folder. Some storage companies offer destruction services—they shred or incinerate your boxes and give you a certificate saying it's done. This protects you if someone later claims you didn't destroy records you were supposed to.

Choosing between storage options

The right choice depends on how much you store, how often you need to find things, your budget, and your industry's rules. A solo consultant with a few client files might use a filing cabinet and a cloud backup. A small business with employees, contracts, and tax records might use a combination: recent documents in the office, older ones in a storage unit, and scans of everything in the cloud. A larger company might use a professional records management company that handles everything.

Before you decide, ask yourself: How many documents do I create each year? How often do I need to retrieve them? What's the cost of my time if I can't find something quickly? What's the cost of a fire or flood? What does my industry require? Once you answer those questions, the storage method usually becomes clear. Then write down your retention schedule, stick to it, and review it once a year to make sure it still fits your business.

Frequently Asked Questions

Can I throw away documents after I scan them?

It depends on the document type and your industry. The IRS allows you to destroy paper tax records after scanning them, as long as the scans are clear and complete. Employee records, contracts, and medical files have different rules. Ask your accountant or industry regulator before you destroy anything, and keep a written record of when and how you destroyed documents.

What if I'm audited and can't find a document?

If the IRS or another agency requests a document and you don't have it, you may face penalties or have to reconstruct the information. This is why a retention schedule and organized storage system matter. If you genuinely lost a document due to fire or theft, document that loss and report it to the agency. It's better than having no explanation.

How much does professional records storage cost?

Costs vary by company and location, but typically range from $50 to $200 per month for a small business, depending on how many boxes you store. Some companies charge per box, others charge a flat rate. Digital storage usually costs $30 to $150 per month depending on file size. Get quotes from a few companies and compare what's included—pickup, delivery, retrieval time, and destruction services.

Do I need to keep records if my business is closed?

Yes. The IRS and state agencies can still audit you for several years after you close. Keep records for the full legal holding period even after you shut down. Once the period ends, you can destroy them, but don't do it before then.

What's the difference between a storage unit and a records management company?

A storage unit is a rented space where you store boxes yourself; you're responsible for organizing and retrieving them. A records management company handles everything—they pick up boxes, organize them, store them securely, retrieve specific documents when you request them, and destroy them when the retention period ends. Records management costs more but saves you time and reduces your responsibility.
