How long should you keep signed contracts?

The short answer

• Contract life plus the limitation period. Keep it while it's in effect, then for your state's deadline to sue on a written contract, counted from the last date anything could have gone wrong.
• Then check the other clocks. Tax records, payroll records, lease disclosures and construction claims each have their own, and the longest one wins.
• Keep the whole package. The signed copy, every amendment and change order, and the record of who signed and when.
• Electronic copies count. A digital record meets a legal duty to keep a contract if it's accurate and can be reproduced later.

The deadline to sue: statutes of limitation

Every state sets how long someone has to file a lawsuit over a broken contract. Written contracts often get more time than spoken ones, and the period generally runs from when the claim accrues, which for a contract usually means the breach. Some examples, from each state's own code:

Sales of goods follow a separate Uniform Commercial Code rule. Ohio's version is typical: an action for breach of a contract for sale must be brought within four years, and the parties can agree to shorten that to no less than one year but can't extend it (Ohio Rev. Code § 1302.98(A)). New York's six-year rule lists the same UCC article as an exception.

Construction work can matter for a decade

For contractors, the contract is evidence in defect claims long after the final invoice. Many states also have a statute of repose, an outer limit counted from when the work was finished:

• Ohio cuts off injury and property-damage claims arising from a defective and unsafe condition of an improvement to real property, against those who designed or built it, ten years after substantial completion, unless a longer express warranty applies (Ohio Rev. Code § 2305.131).
• Washington requires construction claims to accrue within six years after substantial completion or the end of the contractor's services, whichever is later; the ordinary limitation period then runs from there (RCW 4.16.310).

In principle, that lets a contract claim over a Washington job surface more than a decade after the crew left. Keep each job's contract, change orders, lien waivers, warranty and completion sign-off together, at least through your state's repose period.

Tax records: the IRS clocks

Contracts that back up income, expenses or asset purchases are tax records too. The IRS ties how long to keep them to how long it can review a return:

• 3 years from filing, in the normal case.
• 3 years from filing or 2 years from paying the tax, whichever is later, if you claim a credit or refund after filing.
• 6 years if you leave out income that's more than 25% of the gross income shown on your return.
• 7 years if you claim a loss from worthless securities or a bad debt deduction.
• Indefinitely if you don't file a return, or file a fraudulent one.
• At least 4 years after the tax is due or paid, whichever is later, for employment tax records.

Records for property and equipment are kept until the period runs for the year you dispose of it, so the purchase contract for a truck you drive for eight years is needed for eight years plus the return's period. The IRS also points out that insurers and lenders may want records kept longer than it does.

Employment, lease and government contract records

These are federal floors. State law can require more, and an employment contract or a lease is still a contract, so the limitation period above applies to it as well.

Electronic copies are enough

You don't need paper. Under the federal ESIGN Act, a legal duty to keep a contract is met by an electronic record that accurately reflects it and stays accessible to everyone entitled to it, in a form that can be accurately reproduced later (15 U.S.C. § 7001(d)). Section 12 of UETA, the state version, says the same, including for rules that ask for an original.

Two cautions. Keep the file exactly as it was signed, because re-saving it or printing and rescanning it loses the proof that it hasn't changed; how to store signed contracts covers the setup. And keep paper originals where the paper itself matters. A promissory note is the classic case: negotiable instruments fall under UCC Article 3, which ESIGN and UETA leave out, and the person enforcing one generally needs the signed original.

A simple retention schedule

Before you shred anything, check whether a dispute is brewing. Once a lawsuit is threatened or likely, destroying related records can be held against you, so pause the schedule for anything connected to it.

Keeping signed contracts in SignMaster

When the last person signs, SignMaster emails every party the signed PDF with its certificate of completion: who signed, when, their email and IP address, and a SHA-256 fingerprint of each document that shows whether the file has changed since. The envelope stays in your account, and search matches envelope titles, so a consistent naming pattern makes old contracts easy to find. For a second copy, download signed PDFs in bulk, or on Crew and Company use a webhook to save each completed envelope to your own storage.
