Your restaurant cannot legally pay its first employee without a properly completed Employee's Withholding Certificate, a federal W-4 form, on file. The IRS and the Washington State Department of Revenue require this form for every worker to correctly calculate federal and state income tax withholding from their wages. Key facts:

As a Tacoma restaurant employer, you are legally obligated to collect and pay federal income taxes on behalf of your staff. The Employee's Withholding Certificate (Form W-4) is the IRS's mechanism for this, mandated by Internal Revenue Code § 3402. Every time you hire a new employee in Tacoma, you must have a completed W-4 on file. This isn't a city or state form—it's a direct federal requirement from the Internal Revenue Service. The information your employee provides on the W-4 (filing status, number of allowances/dependents) determines precisely how much federal income tax you must withhold from their wages each pay period. Without a properly completed form, you cannot calculate the correct withholding amount, putting your business at immediate risk for penalties.
Getting this wrong has direct, costly consequences. Based on IRS enforcement data and ApronPrep's analysis of common compliance errors, the primary penalties are:
Legal code: Internal Revenue Code (Title 26)
Recent update: The 2026 W-4 form design remains unchanged from the major 2020 revision, which eliminated allowances and refocused on income, dependents, and other adjustments; however, employers must ensure they are using the current year's version as specified in IRS Publication 15-T.
| Type | Required | Notes |

| Restaurant (Full-Service) | Required | Any business with at least one employee, as defined by Washington State law (RCW 50.04.100), must file and maintain this certificate with the Department of Revenue. |

See Full Requirements →Check this box only if you are unmarried, pay more than half the cost of keeping up a home for a qualifying person (like a dependent parent or child), and that person lived with you for more than half the year.
COMMON MISTAKE: Checking 'Head of Household' when you are single with no dependents or when married and living with your spouse, which triggers an incorrect withholding calculation and potential underpayment penalty.
Check this box if you are legally married and will file a joint tax return with your spouse, or if you are a qualifying widow(er) with a dependent child.
COMMON MISTAKE: A married employee checking this box when their spouse also works, but failing to also check the 'Two Jobs' checkbox in Step 2(c), leading to significant under-withholding.
Check this box if you are unmarried, divorced, or legally separated, OR if you are married but choose to file a separate tax return from your spouse.
COMMON MISTAKE: A married employee checking 'Single' to try and have more tax withheld, which is an inaccurate filing status that can cause payroll processing errors and employee liability issues.
Enter your legal first name and middle initial exactly as it appears on your Social Security card (e.g., 'John A').
COMMON MISTAKE: Using a nickname (e.g., 'Johnny'), omitting a middle initial when one is on the SSN card, or including a suffix like 'Jr.' which belongs in the Last Name field.
Enter your legal last name (surname) exactly as it appears on your Social Security card.
COMMON MISTAKE: Including a hyphenated last name partially, using a maiden name when legally changed, or adding suffixes (Jr., Sr., III) without a space after the last name.
Enter your current residential street address, including apartment or unit number, where you receive mail.
COMMON MISTAKE: Entering a P.O. Box here (it should go in the City/State/ZIP field if used), or using the restaurant's business address instead of the employee's home address.
Enter the city, two-letter state abbreviation, and ZIP code for your mailing address (e.g., 'Tacoma, WA 98402').
COMMON MISTAKE: Writing out the full state name (e.g., 'Washington'), using an old ZIP code after a move, or incorrectly formatting the city and state without a comma.
Enter your nine-digit Social Security Number in the format XXX-XX-XXXX, using hyphens.
COMMON MISTAKE: Transposing numbers, omitting hyphens, entering an Individual Taxpayer Identification Number (ITIN) without proper notation, or using a spouse's SSN by mistake.
Check this box if you (or your spouse, if filing jointly) hold more than one job at the same time, or if you are married filing jointly and your spouse also works.
COMMON MISTAKE: Failing to check this box when an employee has a second job, which is the most common cause of severe under-withholding and a large year-end tax bill for the employee.
Enter the total dollar amount of Child Tax Credit you are claiming, based on IRS guidelines for qualifying children, to reduce the income tax withheld from your pay.
COMMON MISTAKE: Entering the number of children instead of a dollar amount, or claiming a credit for a child who does not meet the IRS residency, relationship, age, or support tests.

Many restaurant owners only have their employees complete a W-4 and do not file a separate Employee's Withholding Certificate (Form W-9) for their own legal business entity (LLC, S-Corp, etc.). This is often required by suppliers, payment processors, or for certain tax credits. Failure to have this on file can delay payments from vendors or complicate tax documentation, potentially adding 2-3 weeks to resolve. Always file a W-9 with your restaurant's legal name and EIN, not your personal name and SSN.
The federal Form W-4 was substantially redesigned in 2020 and using a pre-2020 version is a guaranteed rejection. The new form does not use withholding allowances. Submitting an old form triggers a correction request from your payroll provider or the IRS, stopping payroll processing. This adds at least one pay cycle of delay and manual correction. Always download the latest Form W-4 directly from IRS.gov for every new hire.
Washington state requires separate PFML withholdings, reported through the Employment Security Department (ESD). A common mistake is treating the federal W-4 as the sole withholding document and not providing employees with the state-required PFML form or explanations. This leads to under-withholding, creating a liability for the employer at year-end. You must provide the ESD's "Employee Elective Coverage" information and ensure PFML is calculated and remitted separately from federal income tax withholdings.

Collect your Washington State Unified Business Identifier (UBI) number and legal business name exactly as registered with the WA Secretary of State. For each employee, you'll need their Social Security Number (SSN), legal name, address, and federal Form W-4 details. Have your banking information ready if you plan to pay electronically. The most common delay is using a trade name (DBA) instead of the official legal name on file with the state.
Create or access your business account through the Washington Department of Revenue's "My DOR" online portal. From the Business Account Dashboard, navigate to the tax account management section to add the "Withholding Tax" account. You will need your UBI number and business registration information. This step establishes your formal tax account for reporting and paying withheld employee taxes.
Follow the portal prompts to complete your withholding account registration. You'll specify your reporting frequency (monthly, quarterly, or annually) based on estimated tax liability, which is determined by the state. You must also set up your payment method, with electronic payment via EFTPS or the DOR portal being mandatory for most businesses. Failing to correctly assign the reporting frequency based on DOR's determination is a frequent administrative error.

See All RequirementsProcessing times vary. According to the Washington Department of Revenue, this registration is typically processed electronically upon submission. However, allow at least 1–2 business days for system updates and to receive your official registration details before running your first payroll. A related requirement that also requires state processing is your Annual Report Filing. Contact the Department of Revenue to confirm current processing times.
There is no government filing fee to register for an Employee's Withholding Certificate with the state of Washington, per the Washington Department of Revenue's official guidance. This is part of the standard business registration process with the state, so you will not be charged for this specific account. Not legal advice—verify this with the Department of Revenue, as associated tax deposits are required later.
No, you cannot transfer the certificate itself. When your business moves locations within Tacoma, you must update your physical address with both the Washington Department of Revenue for your tax accounts and the City Business License/Registration. This ensures tax withholding and local B&O tax information are correctly tied to your new site to avoid penalty notices.
The registration itself does not renew; it remains active as long as you have employees and file returns. However, you must file quarterly tax returns and make payroll tax deposits with the state. Failure to file these periodic returns can result in account suspension and penalties, as stated on the Department of Revenue's business tax website.
There is typically no physical inspection for this certificate, as it is a tax registration. The state's verification is based on your reported payroll data. However, the Department of Revenue may conduct audits of your payroll records and tax filings to ensure compliance, comparing your records against filed returns. This is a separate process from inspections required for operational permits like a Certificate of Occupancy.
