Lost Income After a California Injury: What to Save

A doctor says you cannot work for three weeks. The employer marks the absence, but the next pay stub only shows fewer hours. A rideshare driver loses access to the app while the car is being repaired. A self-employed contractor cancels jobs, pays a helper to finish others, and watches deposits fall a month later.

All three people may describe the problem as “lost wages.” Their records will not look the same.

California's civil jury instructions distinguish income already lost, future earnings that are reasonably certain to be lost, and a reduced ability to earn money. Those categories require evidence. A handwritten total, one pay stub, or a screenshot showing lower app revenue may identify the problem, but it rarely explains the complete loss.

Important: This article provides general information, not legal, tax, employment, workers' compensation, or financial advice. The availability and measure of any income-loss claim depend on fault, causation, medical evidence, work history, business structure, mitigation, benefits, and the facts of the particular case. Do not alter, recreate, or backdate records.

Start With the Work Restriction, Not the Dollar Amount

An income-loss file should begin with why the injury affected work.

Preserve medical records showing:

• the date the restriction began;
• whether the provider took you completely off work or limited certain tasks;
• limits involving lifting, standing, sitting, driving, typing, concentration, travel, or hours;
• the expected duration and follow-up date;
• changes to restrictions over time;
• the date you were released to return to full or modified work.

A diagnosis alone may not answer the work question. An employer may need to know whether you can drive, lift 25 pounds, stand for four hours, or work a reduced schedule. A self-employed person may need to explain why the same restriction prevented site visits, deliveries, client appointments, or hands-on work.

Ask the medical provider how to document an accurate restriction. Do not ask for a restriction the medical record does not support. Do not change a note yourself because its wording is inconvenient.

Our guide to medical records after a California injury explains how to preserve work notes, follow-up records, billing documents, and the underlying treatment timeline.

Make a Daily Work-Loss Timeline

Create a separate log while dates are still fresh. For each affected day, record:

• scheduled work or planned assignment;
• hours normally expected;
• hours actually worked;
• work missed completely;
• modified or light-duty work performed;
• medical appointment or restriction affecting the schedule;
• job, shift, delivery, contract, or customer work canceled;
• replacement worker or subcontractor used;
• sick leave, vacation, PTO, disability, or other benefit applied;
• source document supporting the entry.

Keep the log factual. “Scheduled for eight hours; employer sent me home after two because no seated duty was available” is more useful than “lost a lot of money.”

Do not count the same period twice. If a person received regular wages through sick leave, later seeks restoration of used leave, and also lists the same days as completely unpaid, those entries need to be identified and reconciled rather than stacked together.

Employees Should Preserve More Than Pay Stubs

Pay stubs are useful because they can show wage rate, hours, overtime, commissions, deductions, and year-to-date totals. But one pre-injury stub and one post-injury stub can mislead if schedules vary.

An employee's file may include:

• pay stubs from a reasonable period before and after the injury;
• W-2 forms and tax records;
• timecards, schedules, shift assignments, and attendance records;
• employer messages about missed work or modified duty;
• written job description and physical requirements;
• medical work-status notes delivered to the employer;
• leave requests and approval or denial notices;
• sick leave, vacation, and PTO statements;
• records of unpaid leave;
• overtime history;
• commission, bonus, tip, or incentive records;
• union wage scales or scheduled raises, when actually applicable;
• return-to-work and accommodation communications.

Ask the employer or payroll department for a written wage-loss statement when appropriate. It should identify the employer, normal rate, typical schedule, dates or hours missed, payments made, leave used, and the source of the information. It should not guess that every available overtime hour or future bonus would have been earned.

Save the original employer response. Do not draft a statement for a supervisor to sign without disclosing how it was prepared and verifying every figure.

Variable Pay Needs a Longer Baseline

Overtime, commissions, bonuses, tips, seasonal work, and changing shifts rarely fit a one-week comparison.

A useful baseline may require:

• several months or prior years of payroll records;
• the same season from earlier years;
• commission statements tied to completed sales;
• tip reports and contemporaneous records;
• scheduled events, projects, or shifts;
• written compensation plans;
• historical overtime actually worked;
• evidence of a raise or promotion that had already taken effect or was sufficiently established.

Separate what was scheduled from what was merely possible. “The manager assigned four overtime shifts in writing before the injury” is different from “overtime is sometimes available.”

Future earnings require more than optimism. California Civil Jury Instruction 3903C says future lost earnings must be reasonably certain to result from the injury. Preserve the documents supporting the anticipated work rather than rounding up to the best month on record.

Gig and App-Based Workers Need Platform Records Before They Disappear

A gig worker may not receive a conventional pay stub. The platform may change dashboards, limit historical downloads, deactivate an account, or show gross customer charges differently from worker payouts.

Preserve, where available:

• weekly and monthly earnings summaries;
• completed-trip, delivery, task, or booking histories;
• hours or active-time reports;
• incentive, promotion, and bonus terms;
• cancellation and acceptance records;
• ratings or account-status notices;
• deactivation or vehicle-eligibility messages;
• 1099 forms and tax records;
• bank deposits that can be matched to platform statements;
• mileage, toll, fuel, rental, insurance, and platform-fee records;
• screenshots showing the date, account, and complete screen context;
• downloadable data exports.

A screenshot of one bad week may show that revenue dropped. It does not show why, what expenses were avoided, whether the account was otherwise available, or what the worker historically earned during comparable periods.

Download records through the platform's ordinary tools. Do not circumvent access controls, edit exports, or create trips or invoices that never existed.

Self-Employed People Must Separate Revenue, Expenses, and Personal Labor

For a self-employed person, business money may move through invoices, deposits, cash receipts, owner draws, payroll, equipment purchases, subcontractors, and tax filings. Gross revenue is not automatically the injured person's lost income.

Preserve the unedited source records:

• federal and state tax returns and supporting schedules;
• profit-and-loss statements;
• general ledger and bookkeeping exports;
• invoices, estimates, contracts, and purchase orders;
• appointment calendars and project schedules;
• customer cancellation or postponement messages;
• bank and payment-processor statements;
• 1099 forms and accounts-receivable records;
• payroll and owner-compensation records;
• receipts and categorized business expenses;
• subcontractor or replacement-worker payments;
• prior-period records for comparison;
• records showing work completed later rather than permanently lost.

Keep three questions separate:

1. What business revenue did not arrive or arrived later?
2. What expenses continued, increased, or were avoided?
3. What value was tied to the injured person's own labor rather than the business as a whole?

A canceled $8,000 project is not automatically an $8,000 personal income loss. Materials may not have been purchased. A subcontractor may have completed part of the work. The project may have been rescheduled rather than lost. On the other hand, rent, insurance, software, payroll, or equipment payments may have continued while the owner could not work.

California's jury instructions separately address lost profits in other types of cases and explain that gross receipts and expenses are different. The instruction also says its lost-profits formulation is not intended for personal-injury cases, which is exactly why a self-employed injury claim should not be reduced to “revenue before minus revenue after.” The legal category and calculation depend on the person's role, business structure, and evidence.

The IRS advises businesses to use a recordkeeping system that clearly shows income and expenses. Tax rules do not determine personal-injury damages, but contemporaneous books are usually more reliable than a spreadsheet created after a claim dispute begins.

Preserve the Records, Then Make a Working Summary

Keep source documents unchanged. Build a separate spreadsheet or ledger with one row per loss item.

Useful fields include:

• date or pay period;
• employer, platform, client, or project;
• work expected;
• work completed;
• gross amount expected;
• amount actually received;
• continuing expense;
• avoided expense;
• replacement-labor cost;
• benefit or leave payment received;
• supporting document;
• note explaining any estimate.

Label estimates as estimates. If a number comes from an average, identify the period and show the calculation. If a customer later pays an invoice, update the summary rather than leaving the amount listed as permanently lost.

Do not edit source PDFs, change bookkeeping entries to improve the claim, backdate invoices, ask a customer to create a false cancellation message, or delete transactions that complicate the picture. Preserve corrections and audit trails.

Past Lost Earnings and Earning Capacity Are Not the Same

California Civil Jury Instruction 3903C describes past lost earnings as the income, earnings, salary, or wages lost to date. It separately addresses future earnings that the injured person is reasonably certain to lose.

Instruction 3903D addresses lost earning capacity: a reasonably certain reduction in the ability to earn money in the future. The comparison is between what the person probably could have earned without the injury and what the person can still earn with it. The instruction says a prior work history is not always required.

That distinction can matter when someone:

• returns to work but can no longer perform the same physical tasks;
• moves to fewer hours or lower-paying work;
• loses access to a career path supported by education or training;
• can work now but faces evidence-supported long-term limitations;
• had limited prior earnings but a demonstrable future vocational path.

A medical restriction does not calculate the financial value by itself. Long-term claims may require employment records, education and licensing history, labor-market information, vocational analysis, medical opinion, and economic analysis. Do not announce a lifetime loss from a short-term doctor's note.

Keep Benefits and Leave in a Separate Ledger

An injured person may receive sick pay, vacation pay, PTO, employer disability benefits, private disability benefits, California Disability Insurance, unemployment-related benefits, or another payment during the same period.

For each payment, preserve:

• program or payer;
• application and supporting documents;
• benefit period;
• gross and net amount;
• tax withholding;
• leave hours deducted;
• medical certification;
• approval, denial, repayment, lien, or reimbursement notice;
• deposit record.

California EDD describes Disability Insurance as a short-term wage-replacement program for eligible workers unable to work because of a non-work-related illness, injury, or pregnancy, subject to its requirements. An EDD benefit decision does not by itself determine fault or the measure of a third-party injury claim.

Do not assume a benefit payment erases a loss, can be counted on top of the same loss, or has no repayment or disclosure consequence. Those questions can depend on the payer, policy, claim, and law. Preserve the figures before drawing conclusions.

If the injury happened at work or in the course of employment, workers' compensation rules and deadlines may apply. A third-party personal-injury claim and a workers' compensation matter can overlap without being the same case. Get advice appropriate to both rather than treating this article as a workers' compensation guide.

Reasonable Return-to-Work Efforts Should Be Documented

California Civil Jury Instructions 3961 and 3962 address losses that could have been avoided through a reasonable return to work. The instructions do not require an injured person to do what is unreasonable or impracticable, and the circumstances matter.

Preserve:

• release-to-work notes and restrictions;
• requests for modified duty;
• employer responses;
• jobs or shifts offered and whether they fit the restrictions;
• attempts to resume work;
• symptoms or medical changes reported after an attempted return;
• applications or retraining steps when relevant;
• reasons an offered task could not safely or reasonably be performed.

Do not return to unsafe work merely to create a paper trail. Do not refuse suitable work without documenting the actual reason. Medical decisions belong with healthcare providers; employment and legal questions may require separate advice.

Share Financial Records Deliberately

Tax returns, bank statements, customer files, and platform exports can contain Social Security numbers, account numbers, unrelated transactions, trade information, and customer data.

Preserve complete originals securely. Before sending records to an insurer, opposing party, or another recipient, identify:

• what was requested;
• the relevant time period;
• which accounts or entities are involved;
• whether a summary is enough for an initial review;
• what redactions may be appropriate;
• whether a formal authorization, subpoena, protective order, or confidentiality process applies.

Do not destroy relevant information under the label of privacy. Do not casually email an unencrypted lifetime of financial records because an adjuster asked for “proof of income” in one sentence.

Our article about what not to sign after a California injury claim explains why the scope of financial and medical authorizations deserves review.

Frequently Asked Questions

Are pay stubs enough to prove lost wages?

Sometimes they establish rate and reduced hours, but they may not explain why work was missed, the normal schedule, overtime, commissions, leave use, modified duty, or the connection to the injury. Pair payroll records with medical restrictions, schedules, employer verification, and a dated work-loss log.

What if I used sick leave or PTO and did not miss a paycheck?

Preserve the leave statements and payroll records. Used leave may still matter, but the legal treatment depends on the claim and facts. Do not list the same period as fully unpaid without also identifying the wages and leave benefits received.

Can a self-employed person use bank deposits to prove the loss?

Deposits can support the timeline, but they rarely tell the whole story. They may combine old invoices, loans, transfers, refunds, sales tax, or revenue generated by other workers. Match deposits to invoices and bookkeeping records, then account for expenses and delayed payments.

What if I had just started a new job or business?

A shorter history can make proof harder, but it does not automatically end the inquiry. Preserve the employment offer, wage rate, schedule, training records, contracts, bookings, prior experience, licenses, business plan, actual early results, and comparable objective records. Avoid projections with no documented basis.

Should I send my complete tax returns to the insurance adjuster?

Do not ignore a legitimate request, but understand its scope first. Tax returns may be relevant, especially for variable or self-employed income, while also containing sensitive or unrelated information. Ask what years, schedules, and issues are being requested and obtain advice before signing a broad financial authorization.

Bottom Line

A lost-income claim should connect three records: the injury-related work restriction, the work that was actually missed or changed, and the financial documents showing the result. Employees, gig workers, and business owners need different proof, but all benefit from preserving original records and separating estimates from established figures.
