Lost income is one of the most significant economic damage categories in California personal injury cases. Victims who miss work during recovery, or whose injuries limit future earning ability, can recover both past wage loss and future diminished earning capacity. The documentation requirements differ between the two, and both require careful preparation to withstand insurance company scrutiny.
Past Lost Wages: What You Already Lost
Past lost wages cover income the injured person was unable to earn from the date of the accident to the date of trial or settlement. This includes: base wages or salary for missed work; lost overtime if the injured person regularly worked overtime that is now documentable; commissions and bonuses with demonstrable pre-injury trajectory; self-employment income; and benefits with economic value (employer-provided health insurance coverage the injury period's COBRA replacement cost, for example). Lost vacation and sick days used because of the accident are also recoverable — the injured person should not have to deplete their paid time off due to the defendant's negligence.
Future Lost Earning Capacity
Future lost earning capacity compensates for the reduction in the injured person's ability to earn income over their remaining work life. It applies when the injury causes permanent or long-term limitations on the type of work the person can perform, the hours they can work, or their career trajectory. Future capacity claims require expert testimony in substantial cases: a vocational rehabilitation expert analyzes the injured person's pre-injury occupational profile, the functional limitations imposed by the injury, and the labor market impact; an economic expert converts the vocational analysis into present value, accounting for future wage growth, inflation, and the appropriate discount rate.
Documenting Wage Loss
Documentation for past wage loss: pay stubs for the three to six months preceding the accident establishing the base wage rate; W-2 forms for the past two years establishing annual earnings; a letter from the employer confirming the dates of missed work and the compensation rate for the missed period; documentation of overtime history if overtime loss is claimed; and medical records establishing the physician's work release status (off work, light duty, restricted hours) for each period of claimed loss.
Self-Employed Wage Loss
Self-employed claimants face additional documentation challenges because there is no employer to confirm missed work. Required documentation typically includes: federal and state tax returns for the past two to three years establishing pre-injury net income; business bank records showing revenue patterns before and after the accident; client contracts or invoices establishing what business was lost; accountant analysis confirming the revenue reduction attributable to the injury versus market or seasonal factors; and the treating physician's documentation of the work limitations creating the income loss.
Expert Testimony in Wage Cases
For past wage loss under $50,000, lay evidence (employer letters, pay stubs) plus medical documentation is usually sufficient. For future capacity claims or significant self-employment losses, vocational and economic expert testimony is typically required to present the claim credibly in negotiation or at trial. Expert fees for vocational and economic testimony range from $5,000 to $20,000 per expert; in cases where wage loss is a major damages component, this investment is standard.
Frequently Asked Questions
Can I recover lost wages in a California personal injury claim?
Yes. Past lost wages — income you were unable to earn from the accident through settlement or trial — are recoverable as economic damages. Future lost earning capacity is also recoverable when the injury causes permanent or long-term work limitations.
How do I prove lost wages to an insurance company in California?
Pay stubs for the period preceding the accident, a letter from your employer confirming missed work dates and your compensation rate, and medical records documenting the physician's work restrictions for each period of claimed loss are the core documentation. Tax returns are required for self-employed claimants.
What if I'm self-employed and can't get an employer letter?
Self-employed claimants document wage loss through tax returns, business bank records, client contracts showing lost business, and accountant analysis. The challenge is establishing that the income reduction was caused by the injury rather than market or seasonal factors — accountant analysis specifically addressing causation is important.
What is future lost earning capacity in a California personal injury case?
Future lost earning capacity compensates for the reduction in your ability to earn income over your remaining work life due to permanent or long-term injury limitations. A vocational rehabilitation expert analyzes functional limitations and labor market impact; an economic expert converts the analysis to present value. Expert testimony is required for substantial future capacity claims.
Can I recover lost overtime in a California personal injury claim?
Yes — if you can document that you regularly worked and were paid overtime before the accident, and that the injury prevented you from continuing to work overtime during recovery or permanently. Pay stubs showing consistent overtime for six or more months preceding the accident are the key documentation.
