You missed six weeks of work after the crash, and now the adjuster wants proof of every dollar. What do you actually need to show?
Most claims rest on three kinds of injury lost wages evidence: records of what you earned before, records of what you missed and medical notes that tie the time off to the injury. An insurer will not take your word for the number. With the right papers, though, an employee, a gig driver or a business owner can show a clear and fair figure.
What California Law Lets You Recover
Civil Code section 3333 sets the general measure of tort damages, which is the amount that makes up for the harm the injury caused. Lost earnings are one of the most common pieces.
California’s civil jury instruction on this point, CACI 3903C, covers past lost earnings and future earnings that are reasonably certain to be lost. So you need to show both the amount and the link to the injury.
Lost Wages Evidence for Employees After an Injury
- Pay stubs covering several months on each side of the injury
- An employer letter listing your pay rate, usual hours and missed dates
- W2 forms and tax returns for recent years
- Sick leave and vacation records
- Proof of lost overtime, tips or bonuses
That employer letter is often the single most useful record. Ask human resources to put it on company letterhead and include your job title and a contact name.
Does Paid Leave Count as a Loss?
Often it does. If you burned sick days or vacation to cover your recovery, you used up something of value that you earned.
California’s collateral source rule, confirmed in Helfend v. Southern California Rapid Transit District (1970), generally keeps benefits from independent sources from reducing your damages. Keep pay stubs or an employer letter that shows exactly how much leave you used.
Injury Evidence of Lost Wages for Business Owners
Business owners and contractors need a different paper trail. Several years of history help, because income often swings from month to month.
- Tax returns, including Schedule C, for recent years
- Invoices, contracts and bank deposits
- Client messages about canceled or delayed work
- Calendars showing booked jobs you could not finish
- Receipts for help you hired during recovery
A bookkeeper or CPA can turn those records into a clean monthly summary. If your returns are missing, the IRS Get Transcript service provides copies of past filings.
Gig and Hourly Work
Uneven pay makes a single stub misleading. Gather several months of earlier records to show your normal pattern.
Rideshare and delivery apps let you download earnings summaries, and bank statements confirm the deposits. Hourly workers can ask for time records and save any posted schedule that shows shifts they had to drop.
Medical Evidence That Links Lost Wages to the Injury
Pay records show what you lost, not why. Your chart fills that gap, so ask each provider to write down work limits and expected time off.
A note that says no lifting over 20 pounds explains why a warehouse worker could not return, and it is often the most persuasive injury evidence for lost wages. Line up each stretch off work with a matching medical record.
State Disability Insurance While You Recover
California’s State Disability Insurance program pays partial wage replacement to eligible workers who cannot do their regular job. For 2026, EDD lists benefits of roughly 70 percent of wages, or 90 percent for lower earners, up to a weekly maximum of $1,765.
Payments begin after a seven day unpaid waiting period. You should file no earlier than nine days and no later than 49 days after the disability begins. The maximum changes each year, so check the current EDD rates page.
Reduced Hours and Light Duty
Some people return to work part time or on lighter tasks at lower pay. That difference counts as a loss as well.
Save the stubs that show the drop and ask your supervisor to note the reason in writing. Physical limits get recorded in specific ways, as shown in documenting back, neck and spinal injuries.
Future Earning Capacity
A serious injury can limit what you earn for years. That claim is separate from missed paychecks and usually needs a vocational review or an economist’s report.
Keep records of lost promotions, job changes and training you could not finish. Those details support a future loss if it becomes part of the claim.
A Sacramento Example
Imagine a West Sacramento warehouse lead hurt when a driver runs a red light on Harbor Boulevard. He earns $28 an hour plus regular overtime, and his doctor keeps him off work for eight weeks.
In this hypothetical, he collects twelve weeks of prior stubs to show typical overtime and gets an HR letter with his schedule. He files for SDI on day ten. His claim file shows wages lost, sick time used and SDI paid, all backed by matching work notes.
Gaps Insurers Find in Lost Wages Evidence After an Injury
- Gaps between work notes and dates claimed off
- Estimates of overtime with no payroll history
- Self-employed income that does not match tax returns
- Social media posts showing work on days claimed off
Lost Wage Questions
Can I claim lost wages if I was paid in cash?
Yes, but proof is harder. Bank deposits, client statements and a written log of jobs can help. If the income was never reported on tax returns, expect the insurer to question it closely, and know that unreported income can create separate tax problems for you.
Do SDI benefits reduce my injury claim?
Usually not. Under the collateral source rule, outside benefits generally do not lower what the at-fault party owes. Keep every SDI payment notice anyway, since a clear record of what you received makes the final accounting easier.
How far back should my pay records go?
A year is a common starting point for steady jobs. Self-employed and seasonal workers often need two or three years of tax returns. Aim for a fair picture of normal earnings, not a single unusually strong or weak month.
Start a single folder now, sorted by period, and add a one-page summary of missed dates and amounts. Matching each pay record to a medical note is what turns paperwork into strong injury lost wages evidence.
