California SDI does not use income limits to decide who gets benefits, but it does use your recent wages to calculate how much you receive each week

State Disability Insurance (SDI) in California has no income threshold that disqualifies you. You can earn $200,000 a year or $20,000 and still receive SDI if you meet the medical requirements. However, the state uses your wages from a specific period — called the base period — to determine your weekly benefit amount. The higher your recent earnings, the higher your weekly check.

This distinction matters because many people confuse "income-based" with "income-tested." SDI is income-based: your past wages shape your payment. It is not income-tested: your current income does not disqualify you or reduce your benefit once approved.

Key Takeaways

  • California SDI has no income limit; you can earn any amount and still receive benefits if you are medically unable to work.
  • Your weekly benefit amount is calculated from your wages during the base period, which is typically the 12 months before you file your claim.
  • The state uses your highest-earning quarter within the base period to set a maximum weekly amount, capped at a state maximum that changes each year.
  • If you return to work part-time while on SDI, your benefit may be reduced by a portion of your new earnings, but you will not lose SDI status because you earn too much.

How the Base Period Determines Your Weekly Amount

When you file for SDI, the state looks back at your wages during a base period — usually the 12 months when ready before you stop working. California divides this into four quarters and uses your highest-earning quarter to calculate a weekly benefit rate. The formula is roughly 60 to 70 percent of your average weekly wage during that quarter, but the state caps it at a maximum weekly amount.

The maximum weekly benefit changes each year. For 2024, the cap is $1,540 per week for regular SDI claims. If your wages during the highest quarter would give you more than this amount, the state pays the cap instead. If you earned very little during the base period — say, you worked part-time or started a new job — your weekly amount will be lower.

You do not have to report your current income to receive SDI. The state only needs to know what you earned during the base period, which it pulls from your tax records and employer reports.

What Happens If You Work Part-Time While Receiving SDI

SDI allows you to work part-time or do light-duty work while receiving benefits, but your payment is reduced if you earn money. The state deducts a portion of your new earnings from your weekly benefit. This is called partial disability. You are not disqualified because you earn too much; instead, your benefit shrinks to account for the income you are generating.

The reduction formula depends on how much you earn. If your weekly earnings are less than your full SDI benefit amount, you receive the difference. For example, if your full benefit is $800 per week and you earn $300 per week at a part-time job, you would receive roughly $500 from SDI (the exact amount depends on the state's calculation method). If you earn more than your full benefit amount, SDI stops temporarily, but you can resume it if your earnings drop again.

You must report any work or income to the state while you are on SDI. Failing to do so can result in overpayment recovery and potential fraud charges.

Income Limits That Do explore to Other California Disability Programs

SDI itself has no income limit, but other California disability programs do. If you are looking at Supplemental Security Income (SSI) or State Supplemental Payment (SSP) — which are different from SDI — those programs have strict income and asset limits. SSI, for example, allows only $2,000 in countable resources for a single person (the limit varies by state and changes annually). These programs are means-tested, meaning your income and assets directly affect whether you may have access to.

If you are receiving SDI and also receive SSI or SSP, your SDI payments count as income toward the SSI or SSP limit, which may reduce those benefits. This is an important detail if you are on multiple programs.

How to Find Your Base Period and Estimated Benefit Amount

Before you file for SDI, you can estimate your weekly benefit by reviewing your recent pay stubs and tax returns. Identify your highest-earning quarter in the past 12 months, divide that total by 13 (the number of weeks in a quarter), and multiply by 0.60 to 0.70. That gives you a rough estimate, though the actual amount may vary slightly based on the state's exact calculation.

When you file your claim through the California Department of Insurance (now part of the Employment Development Department, or EDD), you will receive a notice showing your base period, your calculated weekly benefit amount, and the maximum you can receive. Review this notice carefully. If your wages are missing or incorrect, you can appeal and provide pay stubs or tax documents as proof.

You can also contact the EDD directly to ask about your base period before filing. Having this information ready speeds up the process and helps you understand what to expect.

What Counts as Income for the Base Period

The state counts wages from employment during the base period. This includes regular salary, hourly wages, bonuses, and commissions. Self-employment income is generally not counted unless you are a self-employed person who has elected to be covered by SDI (which is optional in California).

Income from investments, rental property, unemployment benefits, or other sources outside of employment does not count toward your base period earnings. The state is only interested in what you earned as a worker during those 12 months.

If you worked for multiple employers during the base period, the state adds all their wage reports together. If you changed jobs or had gaps in employment, those gaps do not erase your earlier earnings — the state still uses the highest quarter from the entire 12-month window.

Frequently Asked Questions

Can I receive SDI if I have a high income from investments or savings?

Yes. SDI does not consider savings, investments, or non-employment income. You only need to meet the medical requirement — being unable to work due to illness or injury. Your bank account or investment portfolio has no effect on your SDI status or benefit amount.

Will my SDI benefit be reduced if I get a raise at a part-time job?

Your SDI benefit itself does not change based on a raise. However, if your part-time earnings increase, the amount deducted from your SDI payment will increase. The state reduces your benefit by a portion of your new earnings, so a higher wage means a smaller SDI check.

What if I did not work much during my base period?

Your weekly benefit will be lower because it is based on your actual earnings during that 12 months. If you earned very little, your benefit may be minimal. However, you can still receive SDI if you are medically unable to work — there is no minimum earnings requirement.

Does my spouse's income affect my SDI benefit?

No. SDI is based only on your own wages during the base period. Your spouse's income, savings, or employment status does not change your benefit amount or your status as an SDI recipient.

Can the state reduce my SDI benefit because I earn too much from part-time work?

The state does not disqualify you for earning too much, but it does reduce your benefit based on your earnings. If you earn more than your full weekly benefit amount, SDI pauses temporarily. Once your earnings drop, you can resume receiving SDI.
