How to Fill Out California Form DE-88 (w/Examples) + FAQs

California Form DE-88, officially the Payroll Tax Deposit coupon, is the document California employers use to send Unemployment Insurance (UI), Employment Training Tax (ETT), State Disability Insurance (SDI), and California Personal Income Tax (PIT) withholding to the Employment Development Department (EDD). Every employer who pays wages in California must deposit these four taxes on a schedule tied to their federal deposit schedule and their PIT withholding amount, and the DE-88 coupon (or its electronic twin in e-Services for Business) is how that money gets routed to the right account.

Roughly 1.4 million California employers report and deposit payroll taxes through the EDD each year, and the agency reports that more than 99% of those deposits now move through e-Services for Business after the statewide e-file and e-pay mandate under AB 1245 took full effect on January 1, 2018. A late or wrong DE-88 deposit can trigger a 15% penalty plus interest under CUIC § 13052, so getting this coupon right protects real money.

What Form DE-88 Is and Who Must File It

Form DE-88, also printed as DE 88 and DE 88ALL on the booklet version, is the California Payroll Tax Deposit coupon used to remit four state payroll taxes to the EDD between quarterly returns. The four taxes are Unemployment Insurance (UI), Employment Training Tax (ETT), State Disability Insurance (SDI), and California Personal Income Tax (PIT) withholding. The coupon does not replace the quarterly DE 9 and DE 9C returns; it is the cash transmittal that pairs with those returns at the end of each quarter.

Every California employer who has registered for an 8-digit EDD employer account number must file a DE-88 (or the electronic equivalent) every time a deposit is due. That includes corporations, LLCs, partnerships, sole proprietors with employees, nonprofits, public entities, and household employers who hire a nanny, caregiver, or housekeeper and have elected to report under the household employer election. If a quarter passes with zero wages paid, the employer still files a DE 9 and DE 9C, but no DE-88 is needed for that quarter.

The deposit schedule that drives DE-88 timing comes from the California Employer’s Guide (DE 44), which mirrors the federal IRS deposit calendar for PIT withholding and adds California-specific thresholds. Next-day, semiweekly, monthly, and quarterly depositor categories all use the same DE-88 coupon; only the Pay Date and Quarter Covered boxes change. Under the e-pay mandate in CUIC § 13021(g), employers must remit electronically unless they have an approved e-file and e-pay waiver (DE 1245W) on file with the EDD.

Before You Start: Documents and Information You Need

Before you open a DE-88 coupon or log in to e-Services for Business, gather everything you need so you do not stop mid-deposit and risk missing the cutoff. Missing a single number on this list usually means the deposit posts to the wrong account, the wrong quarter, or both.

• 8-digit EDD employer account number. This is your unique state ID printed on every coupon in the DE 88ALL booklet; without it the EDD cannot apply your deposit.
• Federal Employer Identification Number (FEIN). The EDD cross-checks your FEIN against IRS records, and a mismatch can freeze the deposit while staff confirm your identity.
• Pay date of the wages. This is the date you actually paid employees, not the last day of the pay period; the deposit due date is calculated from this date.
• Quarter Covered. You must know which calendar quarter the wages fall in (1, 2, 3, or 4), because deposits are credited by quarter, not by year.
• Gross taxable wages by tax type. UI and ETT use the first $7,000 per employee per year, SDI uses a higher annual ceiling set each year by the EDD, and PIT uses all wages.
• Current UI rate, ETT rate, and SDI rate. Your UI rate comes from your annual DE 2088 Notice of Contribution Rates, and ETT/SDI rates are posted yearly.
• PIT withheld from each paycheck. This is the California income tax you already deducted from employees using the DE 4 and the DE 44 withholding tables.
• Bank routing and account numbers (for ACH Debit/Credit). e-Services for Business needs these to pull funds; a wrong digit causes an NSF and a 10% penalty.
• Prior period adjustments, if any. If you are correcting an earlier deposit, you also need the DE 9ADJ to reconcile the math.
• A copy of your last DE-88 or e-Services confirmation. Keeping the prior confirmation lets you match deposit schedules and avoid duplicating a payment.

Where to Get the Form and How to Access It

The EDD does not let employers print a blank DE-88 from the website because each coupon in the DE 88ALL booklet is pre-printed with the employer’s account number, name, and address in OCR-scannable ink. New employers receive a 28-coupon booklet automatically after registering through e-Services for Business registration, and replacement booklets are ordered by calling the EDD Taxpayer Assistance Center at 1-888-745-3886.

The electronic version of DE-88 lives inside e-Services for Business, the EDD’s free online portal. Once you log in, you choose File and Pay, then Make a Payroll Tax Deposit, and the screen rebuilds the coupon field-by-field with the same boxes as the paper DE-88. The system saves every deposit under your account so you can print confirmations or amend a deposit later.

Employers without internet access or with a documented hardship may request a paper waiver using Form DE 1245W. The waiver lasts one year, must be renewed annually, and only excuses paper filing—it does not extend any deposit deadline. If the waiver is denied, the employer must file electronically or face a 15% noncompliance penalty under CUIC § 1114(b). Tax preparers and payroll services file on behalf of clients through the same e-Services portal using the Power of Attorney DE 48.

Step-by-Step: How to Fill Out Form DE-88 Line by Line

The paper DE-88 has 12 fillable areas, plus the deposit-schedule code and signature block. The electronic version in e-Services for Business uses the same 12 areas in the same order, so this walkthrough works for both. Use blue or black ink on paper, write inside the boxes, and never staple, fold, or tape the coupon to the check.

Box 1: Employer Account Number

This box asks for the 8-digit EDD employer account number assigned when you registered as an employer in California. Write the number with no dashes, no spaces, and no leading “EDD” prefix, in the format 123-4567-8 or 12345678 depending on the coupon revision. Maria Lopez, who runs Lopez Bakery LLC in Fresno, writes 123-4567-8 in Box 1 exactly as printed on her DE 2088 rate notice.

A common edge case: if you bought a business and inherited its account, you must use the new successor account number issued after the DE 4453 successor application, not the seller’s old number. The most common mistake here is transposing two digits, which causes the deposit to post to a stranger’s account and forces a tracing request that can take 6–8 weeks. A widespread misconception is that the FEIN can be used in this box if the EDD number is unknown—it cannot, and a deposit without a valid 8-digit EDD number is rejected outright.

Box 2: Business Name and Address

Box 2 asks for the legal business name and the mailing address on file with the EDD. Print the name exactly as it appears on your DE 2088, including the entity suffix (LLC, Inc., LP) and any DBA in parentheses. Marcus Chen, owner of Chen Construction, Inc. (Chen Builders), writes the full legal name with the DBA in parentheses on the second line.

A common nuance is the P.O. Box question—if your mailing address is a P.O. Box, that is fine for DE-88, but the EDD also wants a physical address on file via Form DE 24. The most common mistake is writing a new address here without first updating the EDD; the deposit still posts, but agency notices keep going to the old address, which causes you to miss penalty letters. A frequent misconception is that changing the address on the coupon updates the EDD record—it does not, only DE 24 does.

Box 3: Pay Date (PP-DD-YY)

The Pay Date is the actual date wages were paid to employees, formatted as MM-DD-YY with two digits per field. This is not the pay-period end date, the check-print date, or the direct-deposit posting date if those differ from the day funds were available to the employee. Aisha Patel pays her three employees by direct deposit on Friday, March 14, 2026, so she enters 03-14-26 in Box 3.

The edge case most filers miss: if a payday lands on a weekend or holiday and you advance it to the prior business day, the advanced date is the Pay Date. The most common mistake is using the pay-period end date, which often shifts the deposit into the wrong week and triggers a late-deposit penalty even though the cash moved on time. A common misconception is that monthly depositors can pick any date in the month—they cannot; each Pay Date drives its own deposit due date under the federal-style schedule in DE 44.

Box 4: Quarter Covered

Box 4 captures which calendar quarter the wages belong to: 1 (Jan–Mar), 2 (Apr–Jun), 3 (Jul–Sep), or 4 (Oct–Dec). Enter a single digit, not a date range and not the month. Janet Williams, paying wages on October 2, 2026, writes 4 in Box 4 because October falls in the fourth quarter.

The trickiest edge case is a Pay Date that crosses quarters—for example, wages earned in March but paid on April 1 belong to Quarter 2, because the Pay Date controls the quarter, not the work date. The most common mistake is matching the quarter to the work period instead of the Pay Date, which causes the deposit to post to the wrong DE 9 reconciliation and produces a “deposit not found” notice the next quarter. A misconception worth correcting is that the EDD will figure out the quarter from the Pay Date—it will not; a blank or wrong Box 4 stops the deposit from clearing.

Box 5: Deposit Schedule Code

This box asks which deposit schedule applies to this specific deposit. Codes are A (Next-Day), B (Semiweekly), C (Monthly), and D (Quarterly), as defined in the California Employer’s Guide DE 44. Carlos Rivera, a semiweekly depositor under federal rules because his lookback liability exceeds $50,000, writes B in Box 5.

An important nuance: California requires a next-day deposit (A) any time accumulated PIT withholding hits $100,000 within a deposit period, even if your normal schedule is monthly or quarterly. The most common mistake is sticking with the assigned annual schedule after a $100,000 trigger, which causes a 15% deposit penalty under CUIC § 13052 on the entire deposit. A common misconception is that the schedule is set once a year and never changes—it changes any time PIT crosses the next-day threshold.

Box 6: UI Contributions

Enter the Unemployment Insurance amount due on this deposit. UI is calculated by multiplying taxable UI wages (the first $7,000 per employee per calendar year) by the UI rate printed on your annual DE 2088. Maria Lopez has a UI rate of 3.4% and paid $14,000 in still-taxable UI wages this pay date, so she enters $476.00 in Box 6.

A common edge case is the new-employer rate: most new California employers pay 3.4% UI for the first 2–3 years before the EDD assigns an experience-based rate. The most common mistake is continuing to compute UI on wages above the $7,000 ceiling, which inflates the deposit and ties up cash until you file the DE 938 refund claim. A misconception is that UI follows the federal FUTA $7,000 ceiling automatically—they share the same dollar amount, but California tracks its own ceiling per employee per state account.

Box 7: Employment Training Tax (ETT)

Box 7 captures ETT, a small training-fund tax of 0.1% on the same UI taxable wage base. Multiply taxable UI wages by 0.001 and enter the result. Marcus Chen had $30,000 in still-taxable UI wages this period, so he enters $30.00 in Box 7.

The edge case here is rate exemption: employers with negative reserve account balances are exempt from ETT for that year, and the DE 2088 will show a 0.0% ETT rate—write 0.00 in Box 7 if so. The most common mistake is using the UI rate by accident in this box, which overstates ETT by 30x or more and is hard to claw back without a DE 938. A misconception is that ETT is optional or waivable—it is mandatory for any employer with a positive reserve, by CUIC § 976.6.

Box 8: State Disability Insurance (SDI)

SDI is withheld from employee wages, not paid by the employer, and Box 8 reports the amount you withheld this pay date. The 2026 SDI rate is set annually and applies to all wages with no taxable wage ceiling after SB 951 removed the cap effective 2024. Aisha Patel withheld $130.00 in SDI from her three employees’ paychecks, so she enters $130.00 in Box 8.

A common edge case is voluntary plan employers who self-insure SDI under an approved Voluntary Plan—they enter only the small assessment portion, not the full SDI. The most common mistake is forgetting to deposit SDI withheld from employees, which is a trust-fund violation that can trigger personal liability for owners under CUIC § 1735. A frequent misconception is that SDI is an employer tax—it is fully employee-paid; the employer is only the conduit.

Box 9: California Personal Income Tax (PIT) Withheld

Box 9 reports the California PIT you withheld from employees using the DE 4 and the DE 44 withholding tables. Enter the total withheld for all paychecks dated on the Pay Date in Box 3. Carlos Rivera withheld $4,820.50 across his payroll on October 2, 2026, so he enters $4,820.50 in Box 9.

An important nuance: bonuses and supplemental wages are withheld at California’s flat supplemental rate (currently 6.6%, or 10.23% for stock options and bonuses), and that withholding gets added into Box 9 with the regular PIT. The most common mistake is depositing federal income tax withholding here by mistake, which sends the wrong amount to the EDD and leaves the IRS short. A misconception is that PIT can be netted against employee refunds—it cannot; only the Form 540 reconciles employee PIT at year-end.

Box 10: Penalty

Use Box 10 only if you are voluntarily adding a penalty to a late deposit. Most filers leave this blank and let the EDD bill the penalty; pre-paying it can stop interest from running. The standard late-deposit penalty is 15% under CUIC § 13052, reduced to 10% in some cases under § 1112.

A common edge case is partial deposits: if you deposit on time but short, the 15% applies only to the unpaid portion. The most common mistake is calculating the penalty on gross wages instead of unpaid tax, which overpays the EDD by a wide margin. A misconception is that paying the penalty here waives the right to abatement—it does not; you can still file a DE 938P abatement request for reasonable cause.

Box 11: Interest

Box 11 is for interest on a late deposit, calculated from the day after the due date through the day you pay. The current EDD interest rate is published twice a year and posted on the EDD interest rate page; for 2026 the rate is in the 7–8% range annualized.

The edge case to know: interest never abates, even when penalty is forgiven, because CUIC § 1113 treats interest as compensation for use of money, not a punishment. The most common mistake is using the IRS interest rate, which differs from California’s. A misconception is that interest stops when you mail the check—it stops when the EDD posts the deposit, so always allow 3–5 business days of buffer.

Box 12: Total Paid

Box 12 is the sum of Boxes 6 through 11. Add UI + ETT + SDI + PIT + Penalty + Interest and write the total in dollars and cents. Janet Williams adds $476 + $30 + $130 + $4,820.50 + $0 + $0 and enters $5,456.50 in Box 12.

A useful nuance: the check or ACH amount must match Box 12 exactly, to the penny. The most common mistake is rounding to the nearest dollar, which causes a small under- or over-deposit that the EDD posts as an unmatched payment. A misconception is that any overpayment is automatically refunded—small overpayments stay as credits on the account until claimed via DE 938.

Signature, Title, Phone, and Date

Below Box 12, the coupon asks for an authorized signature, the signer’s title, a daytime phone, and the signing date. The signer must be an officer, owner, partner, or someone with POA DE 48 on file. Maria Lopez signs as Owner, prints (559) 555-0142, and dates the coupon 03-14-26.

The edge case is e-Services filings, where the signature is replaced by the user’s portal credentials—logging in counts as the signature under CUIC § 13021.5. The most common mistake is letting an unauthorized bookkeeper sign without a DE 48, which voids the coupon. A misconception is that a typed name on paper is acceptable—paper coupons require a wet signature.

How to File the Completed Form DE-88

California offers four filing channels for DE-88, but only two are mainstream after the e-pay mandate. Pick the channel that matches your waiver status, your bank, and your processing-time tolerance.

e-Services for Business (default). Log in at e-Services for Business, choose Make a Payroll Tax Deposit, key the same 12 boxes, and authorize ACH Debit from your bank account. There is no fee, the deposit posts the next business day, and the confirmation number is your proof of filing—save it as a PDF.

ACH Credit (bank-initiated). You instruct your bank to push funds to the EDD using the ACH Credit Addenda format in the EDD Information Sheet DE 231P. Banks usually charge $1–$10 per origination, funds settle in 1–2 business days, and proof of filing is the bank trace number plus the EDD acknowledgment in e-Services.

Paper DE-88 by mail with a check. Allowed only with an approved DE 1245W waiver; mail the coupon and a check (made payable to EDD) to Employment Development Department, P.O. Box 826276, Sacramento, CA 94230-6276. There is no EDD fee; postage is your only cost. Processing takes 7–10 business days, and your proof of filing is the canceled check plus a certified-mail green card if you used USPS Certified Mail.

Credit card via the third-party processor. Official Payments / ACI Payments accepts EDD payroll deposits with a 2.3% convenience fee (minimum $1.00). Funds post in 1 business day, and the processor’s confirmation is your filing proof. Most CFOs avoid this channel because the fee usually exceeds any rewards earned on the card.

What Happens After You File DE-88

Once the EDD receives your DE-88 (paper) or your e-Services confirmation, the system posts the four tax amounts to your account by tax type and quarter, and the cash applies to the earliest unpaid liability in that quarter. You can verify posting in e-Services within 1–3 business days under Account Activity; if the deposit is missing after 5 business days, call the Taxpayer Assistance Center at 1-888-745-3886.

If the deposit was late, the EDD mails a Statement of Account (DE 2176) showing penalty and interest, usually within 30–45 days. You have 60 days from that notice to either pay or file a petition with the California Unemployment Insurance Appeals Board (CUIAB) under CUIC § 1222. Reasonable-cause abatement is available under CUIC § 1112(b).

At the end of each quarter, your accumulated DE-88 deposits must reconcile to the totals on your DE 9 and DE 9C. A mismatch over $1.00 generates an automatic notice asking for a DE 9ADJ adjustment form. Janet Williams, who underdeposited PIT by $200 in Q3, files a DE-88 catch-up deposit and a DE 9ADJ to balance the books before year-end.

Mistakes to Avoid When Filling Out Form DE-88

Each mistake below maps to a specific box, and each one has a direct dollar consequence. Read the list before every deposit—seasoned payroll managers do.

• Wrong EDD account number in Box 1 sends the deposit to a stranger’s account and starts a 6–8 week trace.
• Wrong Pay Date in Box 3 shifts the deposit due date and triggers a 15% late-deposit penalty.
• Wrong Quarter in Box 4 causes the deposit to land in the wrong DE 9 reconciliation and produces a “deposit not found” notice.
• Wrong Deposit Schedule Code in Box 5 misses the next-day rule when PIT crosses $100,000 and triggers a 15% penalty on the whole deposit.
• UI calculated above the $7,000 wage base overpays UI and ties up cash until a DE 938 refund claim clears.
• Using the UI rate for ETT in Box 7 overstates ETT by up to 30x and is recoverable only through DE 938.
• Forgetting to deposit SDI withheld from employees is a trust-fund violation under CUIC § 1735 with personal liability.
• Confusing federal income tax withholding with California PIT in Box 9 sends the wrong amount to the EDD and shorts the IRS at the same time.
• Stapling, taping, or folding the paper coupon jams OCR scanners and routes the coupon to manual entry, delaying posting by 2–3 weeks.
• Mailing without certified mail or using the wrong P.O. Box loses the postmark proof needed to defeat a late-deposit penalty.
• Skipping the signature block on a paper DE-88 voids the coupon and the EDD treats the deposit as unsigned and unposted.
• Rounding Box 12 to the nearest dollar creates an unmatched payment that sits on the account as an unidentified credit.

Do’s and Don’ts of Filing DE-88

• Do file every deposit through e-Services for Business unless you have a current DE 1245W waiver, because e-filing eliminates 90% of OCR errors.
• Do save the e-Services confirmation as a PDF after every deposit; this is your only proof if the EDD later loses the cash.
• Do reconcile DE-88 totals to the DE 9 and DE 9C every quarter, because mismatches over $1 generate automatic notices.
• Do update your address with Form DE 24 before changing it on a coupon, so penalty notices reach you.
• Do monitor your PIT accumulation against the $100,000 next-day threshold every payday, because crossing it changes your schedule mid-quarter.

• Do keep DE-88 records for at least four years, the EDD audit window under CUIC § 1132.

• Don’t mail the paper DE-88 without a waiver—the EDD will return the check and assess a 15% e-pay noncompliance penalty.

• Don’t use the federal Form 941 deposit calendar in place of California’s; the schedules look similar but California adds the $100,000 next-day rule.
• Don’t combine two pay dates into one DE-88; each Pay Date needs its own coupon.
• Don’t let an unauthorized bookkeeper sign the paper coupon without a DE 48 POA on file.
• Don’t pay penalty in Box 10 before requesting reasonable-cause abatement, because pre-payment can complicate the abatement claim.
• Don’t ignore an EDD notice—silence converts a proposed assessment into a final assessment after 60 days under CUIC § 1222.

Pros and Cons of Filing DE-88 on Your Own vs. With Help

Pros of filing on your own (in e-Services for Business):

• It is free, with no EDD fee and no payroll-service markup.
• e-Services posts deposits the next business day, faster than paper or third-party processors.
• You see your full account history in one place, which speeds quarterly reconciliations.
• The portal validates the math and flags arithmetic errors before submission.
• You keep direct control of bank account credentials, reducing fraud exposure.

Cons of filing on your own:

• You bear all liability for mistakes, including 15% deposit penalties and trust-fund personal liability under CUIC § 1735.
• Calculating UI/ETT/SDI/PIT correctly takes payroll software or careful spreadsheet work.
• You must monitor the $100,000 next-day threshold every payday with no automated alert.
• Year-end reconciliation between DE-88, DE 9, DE 9C, and W-2s falls entirely on you.
• A short staffing or sick day can cause a missed deposit and an automatic penalty.

FAQs About California Form DE-88

Is Form DE-88 still required if I file electronically? Yes. The DE-88 boxes are reproduced inside e-Services for Business as the Make a Payroll Tax Deposit screen, so the coupon’s information is required even though the paper form is not.

Can I file a paper DE-88 in 2026? No. Paper DE-88 is allowed only with an approved DE 1245W hardship waiver; otherwise the EDD assesses a 15% e-pay noncompliance penalty.

What is the penalty for filing DE-88 late? Yes, a penalty applies: 15% of the unpaid tax under CUIC § 13052, plus interest at the EDD’s published rate, charged from the day after the deposit due date.

Do household employers use DE-88? Yes. Household employers who elect quarterly reporting use DE-88 (code D in Box 5) once each quarter to remit UI, ETT, SDI, and PIT withholding for nannies and caregivers.

Do I write my FEIN or my EDD number in Box 1? No, never the FEIN. Box 1 takes only the 8-digit EDD employer account number; a FEIN in this box causes outright rejection.

What date goes in Box 3 if payday falls on a Saturday? Yes, the actual date funds were available. If you advanced payday to Friday, write the Friday date; if you delayed to Monday, write the Monday date.

Which quarter do I pick for wages earned in March but paid April 1? Yes, Quarter 2. Box 4 follows the Pay Date, not the work date, so April 1 wages are Q2 even if earned in March.

Do I include federal income tax withholding in Box 9? No. Box 9 captures only California PIT withheld using the DE 4 and DE 44 tables; federal withholding goes to the IRS via EFTPS.

Is SDI calculated on capped wages? No, not since 2024. SB 951 removed the SDI taxable wage ceiling, so SDI applies to all wages with no annual cap.

Can I round Box 12 to the nearest dollar? No. Box 12 must match the check or ACH to the penny; rounding creates an unmatched payment that sits as an unidentified credit.

What if I overpaid UI or ETT on a DE-88? Yes, you can recover it. File a DE 938 refund claim within three years of the overpayment date, per CUIC § 1178.

Can my CPA sign DE-88 for me? Yes, but only with a current DE 48 Power of Attorney on file with the EDD; otherwise the signature is invalid.

How long must I keep DE-88 records? Yes, at least four years, the EDD audit window under CUIC § 1132; payroll professionals usually keep them seven years to align with IRS rules.

Does ETT ever go to 0.0%? Yes. Employers with negative reserve account balances pay 0.0% ETT for that year, and the DE 2088 will show the rate; enter 0.00 in Box 7.
