Overview

Illinois uses a 5-year default statute of limitations for general personal injury and negligence claims. In other words, if your matter is a standard injury or negligence claim and no more specific rule applies, the general filing window is 5 years under the jurisdiction data referenced for this page: 720 ILCS 5/3-6.

For a statute-of-limitations check, DocketMath’s statute of limitations tool can help you map the key dates that control whether a claim is still timely. The most important inputs are usually:

• the date of injury
• the date the injury was discovered, if discovery matters
• the filing date
• whether the claimant was a minor or had a legally recognized disability
• whether any tolling event may apply

What this page covers

This reference page gives you the default Illinois rule for general personal injury and negligence claims. It is designed for fast issue-spotting, not case-specific legal advice.

Use this page to:

• confirm the baseline deadline
• understand how the start date affects the expiration date
• identify common exceptions and tolling issues
• see the statutory citation used for this jurisdiction
• run the deadline through DocketMath for a quick date check

Limitation period

Illinois’ general period for personal injury and negligence claims is 5 years. That means a claim generally must be filed within 5 years of the date the cause of action accrues, unless an exception changes that result.

How the deadline usually works

A statute of limitations answer depends on two dates:

1. Accrual date — when the legal claim starts to run.
2. Filing date — when the complaint is filed in court.

If the filing date is after the limitations period expires, the claim is typically time-barred.

Practical examples

What users should enter into DocketMath

To get the cleanest result, enter:

• incident date or accrual date
• discovery date, if you are evaluating latent injury or delayed discovery
• filing date or intended filing date
• any facts suggesting tolling
• the claimant’s age or disability status if relevant

How outputs change

A deadline calculator will generally output:

• the last day to file
• whether the claim is timely or expired
• how many days remain
• whether a potential exception changes the result

Fast checklist

Key exceptions

Illinois has exceptions that can change the ordinary 5-year rule, even when the general statute starts at 5 years. The most common issues are accrual timing, tolling, and claim-specific statutes that override the general rule.

1) Discovery-based accrual

Some claims do not accrue on the day of the underlying event. Instead, the limitations clock may begin when the injury is discovered, or reasonably should have been discovered. That matters in latent injury cases, delayed-diagnosis situations, and other claims where harm is not immediately obvious.

What changes in practice

• If the injury was immediately known, the clock usually starts right away.
• If the injury was hidden, the deadline may start later.
• The discovery date can be the difference between a timely case and an expired one.

2) Tolling for legal disability or minority

Certain claimants may receive extra time if a tolling rule applies. Common examples include:

• minority
• legal disability
• other court-recognized tolling circumstances

These facts can pause or extend the running of the period. The exact effect depends on the statutory rule and the claimant’s status.

3) Claim-specific statutes can override the default

This page states the general/default period only. A different statute may apply to a specific injury type, such as a medical, product, government, or professional liability claim. When that happens, the specific rule controls over the general one.

4) Fraudulent concealment or delayed knowledge

If a defendant allegedly concealed key facts, the filing window may be affected. That kind of issue often turns on detailed facts and how the court treats accrual and tolling together.

Common timing questions

Statute citation

The cited Illinois general statute for this reference page is 720 ILCS 5/3-6, with a 5-year general limitations period for personal injury / negligence as provided in the jurisdiction data for this page.

Citation details

How to use the citation

When reviewing a file, match the statutory rule to the facts in this order:

1. Identify the claim type
2. Check for a claim-specific statute
3. Determine the accrual date
4. Apply the 5-year period
5. Look for tolling or exception facts

That sequence helps avoid deadline mistakes, especially when the injury date and filing date are close together.

Why the citation matters

A deadline is only as good as the statute behind it. Using the actual Illinois citation gives you a defensible reference point when you are:

• calendaring deadlines
• screening cases
• comparing filing dates against accrual dates
• documenting why a claim appears timely or untimely

Use the calculator

DocketMath’s statute of limitations tool helps you turn the Illinois rule into a filing deadline in seconds.

Inputs that matter most

What the calculator shows

You can use the tool to see:

• the deadline date
• the time remaining
• whether the claim is within the limitations period
• how changing the accrual date changes the result

Suggested workflow

1. Enter the earliest plausible accrual date.
2. Add the filing date.
3. Check whether the claim is still within 5 years.
4. Adjust for discovery or tolling facts if they exist.
5. Compare the result against any specific statute that may apply.

When to rerun the calculation

Recalculate if you discover:

• a different injury date
• a later discovery date
• a minor or disability issue
• facts showing concealment or tolling
• a more specific statute for the claim type
