SSI State Supplement Payment in Washington 2026: How Much You Get

Washington pays a State Supplemental Payment (SSP) on top of federal Supplemental Security Income. The standard rate is $33.00 a month as of July 1, 2026, down from $35.50, under WAC 388-478-0055. A separate group of "grandfathered" recipients gets between $0.54 and $199.77 a month, and SSI recipients living in a medical institution get a supplement that raises their $30 federal institutional payment up to Washington's $108.74 personal needs standard. The SSP comes from the Department of Social and Health Services (DSHS), not from Social Security, and it arrives as a separate payment.

Most people never apply for it. DSHS opens the SSP automatically once Social Security approves your SSI. This guide covers the exact 2026 amounts by category, who administers each one, why the rate went down in July, and what to do if your supplement is missing.

Washington SSP Payment Amounts for 2026

Category	Monthly SSP	Administered by
Aged 65 or older on SSI	$33.00	DSHS Economic Services Administration
Blind as determined by SSA	$33.00	DSHS Economic Services Administration
Disabled as determined by SSA	$33.00	ESA or DDA, depending on the case
SSI recipient with an ineligible spouse	$33.00	DSHS Economic Services Administration
Grandfathered (Mandatory Income Level) clients	$0.54 to $199.77, varies by person	DSHS Economic Services Administration
SSI recipient in a medical institution	Raises the $30 federal payment to the $108.74 state standard, a difference of $78.74	DSHS
Client determined eligible by DDA	Set by the Developmental Disabilities Administration	DSHS DDA
Foster child in DCYF Behavior Rehabilitation Services, not IV-E eligible	Set by DCYF	DSHS / DCYF

Amounts come from WAC 388-478-0055 as amended by WSR 26-11-010, effective July 1, 2026, and from the Health Care Authority's Apple Health Income and Resource Standards chart (form HCA 19-0096, 07/26) for the $108.74 institutional personal needs allowance.

You can only get one SSP payment per month. If you fall into two categories, DSHS pays the single applicable standard, not both.

How the Supplement Stacks on the Federal SSI Payment

The 2026 federal benefit rate (FBR), after the 2.8 percent cost of living adjustment, is $994 a month for an individual and $1,491 for an eligible couple. Washington's SSP is added on top.

Situation	Federal SSI	Washington SSP	Combined monthly total
Individual living in own household	$994	$33.00	$1,027.00
Individual living in someone else's household (shared living rate)	$663	$33.00	$696.00
Eligible couple, both aged 65+	$1,491	$66.00 ($33 each)	$1,557.00
SSI recipient with an ineligible spouse	Varies with spousal deeming	$33.00	Federal amount plus $33
Grandfathered client	Varies	$0.54 to $199.77	The higher of the December 1973 state standard plus COLAs, or the current standard

Two details worth knowing. First, a married couple where both spouses are 65 or older receive the SSI couple rate, and each spouse gets a separate $33 SSP. DSHS's own eligibility manual uses that example directly. Second, the shared living FBR of $663 (two thirds of the full rate, applied when you live in another person's household and get food and shelter from them) does not change your SSP. The $33 standard is flat.

Why the Rate Dropped from $35.50 to $33.00

This is the part almost nobody explains, and it is the reason Washington's supplement amount is a moving target.

Federal rules at 20 C.F.R. sections 416.2095 through 416.2099 require Washington to spend a set minimum amount on SSP benefits each calendar year in order to keep drawing down federal Medicaid funds. It is a fixed pot, not a per person entitlement. WAC 388-478-0057 spells out what happens on both sides of that pot:

If there is money left over, recipients get a one-time additional payment, usually at the end of the calendar year.
If there is a shortfall, DSHS reduces everyone's monthly SSP to keep total spending at the required level.

That second clause is what produced the July 2026 change. DSHS filed WSR 26-11-010 on May 11, 2026 specifically to "stay within available state funds to support this spending requirement," and the amendment struck $35.50 and inserted $33.00. Nothing about your individual case changed. The pot did.

Expect this number to move again. The rule also says SSP rate standards "may be adjusted at the end of the calendar year," so a year end bonus payment or a January revision is normal, not an error.

Who Actually Gets the Washington SSP

WAC 388-474-0012 lists eight qualifying groups. You can get an SSP if you are:

A grandfathered SSI recipient (someone converted from a state disability program in December 1973)
An SSI recipient with an ineligible spouse
Receiving SSI because you are age 65 or older
Receiving SSI because you are blind
Receiving SSI because you are disabled
Determined eligible for SSP by the Developmental Disabilities Administration
An SSI eligible foster child getting DCYF Behavior Rehabilitation Services and not eligible for Title IV-E foster care reimbursement
An SSI recipient in a medical institution whose SSI was cut to the institutional payment standard

Two hard requirements sit underneath all of that. You must actually receive an SSI cash payment in the month, and your SSI living arrangement code on Social Security's State Data Exchange record must be A, B, or C. If your SSI is suspended for a month, or reduced to zero by countable income, the SSP for that month goes away too.

The DDA path is closed to new enrollees

Here is a distinction that trips people up. DSHS runs SSP through two different systems. The Economic Services Administration authorizes it through ACES for Mandatory Income Level, ineligible spouse, aged, and blind SSI clients. The Developmental Disabilities Administration authorizes it separately through SSPS for its own clients with developmental disabilities.

The DDA supplement is currently closed to new enrollees, with one exception: SSP Pre-Vocational Legacy (PVL). To qualify for PVL you have to be an enrolled DDA client, have exited a DDA Prevocational employment service after September 1, 2015, not currently be in a Prevocational program, not be in residential services (Companion Home, Alternative Living, Supported Living, SOLA, Group Home, Foster Home, or Staff Residential), and be eligible for or receiving SSI cash assistance or Social Security Title II benefits as a disabled adult child.

The ESA side is not closed. If you are 65 or older, blind, grandfathered, or have an ineligible spouse, the standard $33 payment is still being opened for new SSI approvals.

SSDI and the Washington Supplement

The SSP is tied to SSI, not to SSDI. If your only benefit is Social Security Disability Insurance, you do not get a Washington state supplement.

Two exceptions matter:

Concurrent recipients. If your SSDI check is low enough that you also qualify for SSI, you get both, and the SSP rides on the SSI side.
Disabled adult child (DAC) beneficiaries under DDA. DDA's SSP rules cover people who receive Social Security Title II benefits as a disabled adult child and "would be eligible for SSI if it were not for the receipt of these benefits." That path still runs through DDA, so the closed-to-new-enrollees limit applies.

If you are on SSDI and unsure whether you also qualify for SSI, the deciding factors are the 2026 SSI resource limits ($2,000 for an individual, $3,000 for a couple) and whether your total countable income lands under $994. Washington's SSI income limits guide walks through the deeming and disregard math.

How to Get the Payment

There is no separate SSP application. This is the single most common misunderstanding about the program.

Step 1: Apply for and get approved for SSI. File with the Social Security Administration at ssa.gov/apply/ssi, by calling 1-800-772-1213, or at a local Social Security office. Washington does not make this determination.

Step 2: Wait for the automatic open. Once SSA approves you, your record flows to DSHS through the State Data Exchange. ACES opens most SSP cases automatically. If the system cannot auto-open the case, it generates an alert for a DSHS worker to open it manually.

Step 3: Watch for a separate payment. SSA issues your SSI. DSHS issues your SSP by warrant (a paper check) or EFT. They are two different payments from two different agencies, which is why people sometimes think the supplement never arrived when it simply landed on a different day or in a different form.

Step 4: Do nothing to keep it. No eligibility reviews are required for SSP. It continues as long as you keep receiving an SSI cash payment and stay in a qualifying category.

If your SSP has not shown up a month or two after SSI approval, call the DSHS Customer Service Contact Center at 877-501-2233 (TTY users dial 1-800-833-6384 for Washington Relay), 8 a.m. to 5 p.m. Monday through Friday, or visit a Community Services Office. For questions specific to the DDA supplement, DSHS lists heather.lum@dshs.wa.gov as the program contact.

One warning: SSP is not approved retroactively. It begins the first of the month in which SSA's records show you received a federal SSI cash payment. If a case sits unopened for six months, you do not get six months of back supplement. That is the reason to call rather than wait.

What the SSP Does and Does Not Affect

Program	Effect of receiving SSP
Basic Food (SNAP) and WASHCAP	Counts as unearned income, including SSP issued by DDA. It can slightly reduce your food benefit.
Apple Health (Medicaid)	No effect on eligibility. SSI recipients get categorically needy Apple Health from the first of the month of SSI eligibility.
ABD cash assistance	An ineligible spouse of an SSI client is not eligible for ABD cash.
Overpayment recovery	There are no ACES overpayments for the SSP program, and overpayments from other programs cannot be recouped from your SSP.

That last row is genuinely protective. If DSHS is collecting an overpayment from another benefit, it cannot take it out of your state supplement.

Frequently Asked Questions

How much is the SSI state supplement in Washington in 2026?

$33.00 a month for most recipients as of July 1, 2026. Grandfathered clients get between $0.54 and $199.77 depending on their December 1973 state standard. SSI recipients in a medical institution get a supplement that raises the $30 federal institutional payment up to Washington's $108.74 personal needs allowance.

Do I have to apply for the Washington State Supplemental Payment?

No. DSHS opens the SSP automatically once Social Security approves your SSI, usually through the ACES system without any action from you. If it does not open automatically, a DSHS worker is alerted to open it manually.

Why did my Washington SSP go down in July 2026?

DSHS amended WAC 388-478-0055 effective July 1, 2026, lowering the standard rate from $35.50 to $33.00. Federal rules require the state to hold total SSP spending at a fixed level each year, so when funds run short, DSHS reduces individual payments across the board rather than cutting people off.

Is the SSP paid with my SSI check?

No. Social Security issues the federal SSI payment. DSHS issues the SSP separately, by warrant or electronic funds transfer. They usually arrive on different schedules.

Can I get the SSP if I only receive SSDI?

Generally no. The supplement requires an SSI cash payment in the month. The exception is a disabled adult child receiving Social Security Title II benefits who would qualify for SSI but for those benefits, and that route runs through DDA, which is closed to new enrollees except for the Pre-Vocational Legacy category.

Does the state supplement count against my food benefits?

Yes. DSHS counts all SSP benefits as unearned income for Basic Food and WASHCAP, including SSP issued by the Developmental Disabilities Administration.

What happens if both spouses get SSI and are over 65?

Each spouse receives a separate $33 monthly SSP. The couple receives the SSI couple rate of $1,491 plus $66 in state supplement, for $1,557 total.

Can I get back pay for months my SSP was not opened?

No. DSHS does not approve SSP retroactively. The payment begins the first of the month in which state records show you received a federal SSI cash payment, so contact DSHS promptly if the supplement has not started.
