How much does SIBTF pay, and when does the money come? From the award to the first check

How much does SIBTF pay? The answer in one place

The rest of the combined disability, less two things, set by the Board.

The Subsequent Injuries Benefits Trust Fund, usually called SIBTF, pays workers who were already disabled before a work injury, when the old disability and the new injury together are severe: a combined permanent disability of 70% or more, and one of two gateways measured on the new injury alone. Once a claim clears those, the money question has a short answer and a long one.

The short answer: no statute names a dollar figure. The fund pays what the statute calls compensation “for the remainder of the combined permanent disability existing after the last injury.” In practice that is three steps of arithmetic:

1. The value of the combined disability. The old disability and the new injury, rated together.
2. Less the employer’s share. What is due from your employer on the new injury alone.
3. Less the credits. Money you were already paid for the old disability, with three exceptions.

What is left is the fund’s award. At a combined rating of 70% or more, which every fund claim now needs, a life pension comes with it.

Who decides the number. The Appeals Board fixes and awards the amount of the fund’s benefits, and directs the Director of Industrial Relations, as the fund’s trustee, to pay it. The adjusterClaims administrator / adjuster The person handling your claim for the insurer or self-insured employer. does not choose the figure; the award does.

The long answer is the rest of this article: each step of the arithmetic, the date the payments must start, and the form they come in.

SIBTF after SB 171: who qualifies A prior disability and a new work injury? What SB 171 changed

What the fund pays: the remainder of the combined disability

Additional permanent disability, and a life pension at 70% or more.

It is permanent disability money. The statute defines the fund’s benefits as “additional permanent disability payments due to an eligible employee.” Medical treatment and temporary disabilityTD / TTD / TPD Temporary Disability, Total or Partial. Wage replacement while recovering. Two-thirds of average weekly earnings; 2026 maximum $1,764.11/week. stay with the claim against your employer. The fund pays the permanent disability your employer is not liable for, because your employer is liable only for the share its injury caused.

It is measured on the combined disability. Your employer’s share is the new injury alone, after apportionmentApportionment Dividing permanent disability between industrial and non-industrial causes. It is to disability, not to findings on an image., the process that takes out the part of a disability blamed on other causes. The fund’s share is what is left of the combined rating once the employer’s part is taken out. The combined rating counts because the old disability and the new injury together limit you more than either alone.

At 70% or more, a life pension. A permanent disability rating of 70% or more earns a payment for the rest of your life, beginning when the permanent disability weeks run out and rising each year with the state average weekly wage. An employer whose injury alone is rated below 70% owes no life pension at all. When the combined rating reaches 70%, the fund pays it. For most fund claims the life pension is the larger part of the value, because it does not end.

What it does not depend on. The old disability can come from anything: a car accident, an illness, a condition you were born with, an earlier work injury. It is measured as it was on the date of the new injury. A fund claim also survives a compromise and releaseC&R — Compromise and Release A lump sum that closes future medical treatment permanently. of the case against your employer, though how that case closed can decide a great deal, as the credits section shows.

Permanent disability: the weeks, the rate and the life pension

One illustrative award: 40% from the employer, 85% together

The life pension the employer never owed.

Take the custodian’s case, as illustrative as every figure in it. Her new injury, the right knee, is rated 40% permanent disability on its own. The old left knee and the new right knee, rated together, come to 85%.

• The employer pays permanent disability on the 40%. At 40% she is below the 70% that earns a life pension, so the employer owes none.
• The fund pays the difference between the value of 85% and the value of 40%, less any credits.
• The fund also pays the life pension, because the combined rating is 85%.

The life pension, computed. The life pension is 1.5% of the rating above 60, multiplied by weekly earnings counted up to a set figure. With weekly earnings at or above the $515.38 the formula counts, an 85% combined rating gives 1.5% × (85 − 60) × $515.38 = $193.27 a week, for life. It starts after the permanent disability weeks run out and rises each year with the state average weekly wage.

What a fund claim is worth over time. State-commissioned modeling of a hypothetical 50-year-old worker put the present value of the fund’s liability at about $100,000 at a combined rating of 70% and about $900,000 at 100%. Those are averages from a model, not a value in any case, and SB 171 now makes both ratings harder to reach. They show why the life pension, not the permanent disability weeks, is usually where the money is.

Why the underlying case matters. The same research found that fund cases whose underlying claim closed with Stipulations or a Findings and AwardF&A Findings and Award. The judge’s decision. averaged roughly $649,000 in present value, and those closed by Compromise and Release roughly $48,000. A compromise and release is a lump sum with no stipulated permanent disability rating, and the fund takes credit for what you were paid. If the fund may be in play, the structure of the underlying settlement has to account for it before anything is signed.

The employer owes the new injury. The fund owes the rest, and at 70% the rest includes a payment that does not end.

C&R or Stipulations: the two structures

The credits: what comes off the fund’s award

Money already paid for the old disability, with three exceptions.

SB 171 rewrote the credit section, and it is short. The fund’s benefits “are not in addition to but shall be reduced to the extent of any monetary payments received by the employee, from any source whatsoever, for or on account of the preexisting disability or impairment.” The section adds that it “shall be given broad interpretation to prevent double recovery.”

What counts. Money paid to you for or on account of the old disability, from anyone. An earlier workers’ comp award or settlement for the old injury is the plainest example. Which other payments were made on account of the old disability is a question of fact in each case, and it is often where the arguments are.

The three exceptions. The reduction does not apply to:

• A military disability pension. Payments being made, or due, as a pension or other compensation for disability incurred in service in the armed forces of the United States.
• Certain public assistance. Assistance under the parts of the Welfare and Institutions Code the section lists.
• What it cost to recover. A sum equal to the attorney’s fees, costs and expenses reasonably spent to recover the payments for the old disability.

Worked through, illustrative. Say the custodian had settled a claim for an old injury, years ago, for $30,000, and $4,500 of it went to attorney’s fees and costs. The fees are one of the three exceptions, so the credit is $30,000 less $4,500: $25,500. The fund’s award is reduced by $25,500, not by $30,000.

The paperwork is yours to give. If you apply to the fund, you must give the Director the documentation and other information the Director asks for about payments for the old disability. A dispute over those payments may not be the subject of a Declaration of Readiness to ProceedDOR Declaration of Readiness to Proceed. Forces the calendar. You have 10 calendar days to object, or objections to proceeding on its issues are waived., the filing that asks for a conference or trial, until the Director has the documents. A credit dispute with missing papers does not get a hearing date.

I have an old injury and a new one

When does the money come? 30 days from a final determination

The clock starts when the decision can no longer be reviewed.

SB 171 gave the fund its first payment deadline. The statute now says: “Any payments by SIBTF under this article shall commence within 30 days of the final determination of SIBTF liability.” Before July 2026 there was no statutory payment clock on the fund at all.

What “final determination” means. The statute defines it as “final resolution by judicial determination, review, appeal, and writ.” The judge’s award is the judicial determination. The determination is final once the review that follows it is over, or the time to ask for it has run out:

• Reconsideration. A party who disagrees with a final decision has 20 days to petition the Appeals Board for reconsideration. If no one petitions, the award becomes final when those 20 days run out.
• If someone petitions. The Board has 60 days from the day the trial judge transmits the case to it to act, or the petition is deemed denied.
• A writ. After the Board acts, a party has 45 days to petition the Court of Appeal for a writ of review.

So the 30 days run from the end of that chain, not from the day the award is signed. An award no one challenges starts its clock 20 days later. An award someone challenges waits for the Board and any writ first.

One award, dated (illustrative). The judge’s Findings and Award in the custodian’s case issue on August 3, 2026. Counting the 20 days from the award, no one petitions by August 23, 2026, and the award is final that day. The fund’s payments must begin within 30 days: by September 22, 2026.

Write down two dates. The day the award became final, and the day 30 days after it. If the second passes with nothing paid, that is a violation of the statute, not merely a slow agency.

The claim, start to finish

Is SIBTF retroactive? What the new sentence says

Liability begins at the final determination, after the credit.

People ask whether the fund’s money reaches back: to the date of the injury, the date the employer’s payments ended, or the date the claim was filed. SB 171 added a sentence that speaks to it. The fund’s liability “for any additional permanent disability benefits under this article shall commence upon a final determination of SIBTF liability and after any reduction pursuant to Section 4753,” the credit section.

What it says, read plainly. Two things. The fund’s liability begins upon the final determination. And it begins after the credit for payments on the old disability has been taken.

What it does not say. The sentence does not say how an award counts the months before the final determination, and it does not set a lump sum for them. The sentence is new with SB 171. How the Appeals Board applies it to a particular award, and to the period between the end of the employer’s permanent disability and the final determination, is a question to put to whoever handles your claim, with the award in hand.

Why the credit order matters. Read with the credit section, the order is: the award, the credit, then the payments. A large credit can mean the first months of the fund’s liability are absorbed by money you were already paid, before any check goes out. The award, and the fund’s calculation under it, should show that arithmetic. Ask for it in writing.

Which side of June 1, 2026

Weekly or a lump sum: how the payments arrive

An award pays over time; a compromise pays once, if the Board approves it.

Under an award. The fund’s benefits are additional permanent disability payments, and at 70% or more a life pension. They are paid over time under the award, not as a single check, and the life pension continues for life, rising each year with the state average weekly wage.

One sum, by compromise. The Attorney General or the Department of Industrial Relations may settle a fund claim by compromise and release. No such compromise is valid unless the Appeals Board approves it. That is the only route to a single payment that ends the fund claim, and it trades the life pension for whatever the compromise pays.

Before you compromise with the fund. A compromise ends the fund claim for good, and with it a payment that would not end. Weigh the sum offered against the life pension the award would pay, at your age, with its yearly increases. The 30 days in the statute are written for a final determination of liability; ask how and when a compromise will be paid before you sign it.

Fees. A lawyer’s fee on a fund award is set by a judge, as every fee in a California workers’ comp case is. An attorney may not take a fee until a judge has approved or set it.

What does a workers’ comp lawyer cost?

Who pays, and who to ask about a payment

The Board awards it; the Director pays it; an adjuster handles it.

The Appeals Board fixes the amount and directs the Director of Industrial Relations, as trustee or administrator of the fund, to pay what it awarded.

The Director pays. Before SB 171, payment was administered by the State Compensation Insurance Fund; the amended statute puts it with the Director.

The adjuster. The Director assigns the claims adjustment, and may do it within the Department of Industrial Relations or by contract with the State Compensation Insurance Fund or outside vendors. The person who processes your payment is the adjuster assigned to your fund claim, whoever employs them. The award, the fund’s claim number and that adjuster’s name belong on one page in your file.

The other side’s lawyers. In the case itself, the fund is represented by the Attorney General or by attorneys of the Department of Industrial Relations. A question about the amount goes to the case; a question about a check that has not arrived goes to the adjuster first, in writing.

How long until the award: the honest timeline

Slow claims, a backlog, and a new deadline on your side.

The 30 days are the end of a long road. Fund claims have historically taken five to ten years to resolve. The state’s 2024 study counted just over 15,000 cases pending at the start of 2023, against 1,284 resolved with benefits in 2022. Of 27,047 cases from 2010 through 2022 that the state’s researchers followed, about 24% had been resolved with benefits and about 54% were still unresolved. The backlog reached roughly 25,000 unprocessed cases against a processing rate of 500 to 1,000 a year.

Where claims stall. In the paperwork. You must give the Director the documentation the Director requires to decide eligibility, and the documents about payments for the old disability. Treat a records request as a deadline even when it does not arrive with one.

Your own deadline. SB 171 also gave fund claims their first statute of limitations: five years from the date of the new injury, or six months from the resolution of permanent disability in that claim, whichever is later. Write both dates down; the later one is the deadline. If either is close, ask.

What the backlog does not change. The 30 days. However long the road to the award, once the determination is final, the fund has 30 days to begin paying.

Already settled: what can still be done

When the check is late, and a file for the award

Count the days, write once, and keep the copy.

If 30 days have passed since the final determination and nothing has arrived:

1. Check the date you are counting from. The end of the 20 days to petition, or the end of any petition and writ, not the award’s own date.
2. Write to the fund’s adjuster. Give the claim number, the award’s date, the date it became final, and the date the 30 days ended. Ask when the first payment will issue and how it was calculated.
3. Keep a copy and a record of the date sent.
4. Raise it in the case if the payment does not follow. A missed statutory deadline is something the Appeals Board can be asked to look at.

A file to keep. One folder, started when the award comes:

• The award — The Findings and Award or the order approving a compromise, with its date.
• The date it became final — And the date 30 days later.
• The fund’s claim number and adjuster — Name, address, and how they prefer to be reached.
• The old claim’s papers — The award or settlement for the old disability, and the fee order that went with it.
• Every records request — When it came, and what was sent back, when.
• The fund’s calculation — The credit, the date liability began, the first payment, the life pension.
• Every payment received — Date and amount, as they arrive.

When you do not need a lawyer for this

Some questions are arithmetic; some are not.

You may not need one to count the 30 days from a final award, to write to the adjuster about a late check, or to keep the file above. Those are dates and copies.

You will want one for the questions that decide the money: whether a payment counts as a credit, how the new sentence on when liability commences applies to your award, whether a compromise offered by the fund is worth the life pension it ends, and how the underlying case should close if the fund may be in play. These are claims against the state, defended by the Attorney General or the Department’s attorneys, and the statute was rewritten in July 2026.

Honest odds. The bar to reach the fund is higher than it was before SB 171, and the claims are slow. The money, when it comes, can include a life pension the employer never owed. That is why the question is worth asking even when the answer is no. A consultation with this office costs nothing, and if there is nothing worth doing, we will tell you that.
