Why You Need a Employee's Withholding Certificate
Employees' withholding certificates are mandated by federal law. Every employer in Detroit, Michigan, must collect Form W-4 from each new employee under the Internal Revenue Code (Title 26), Section 3402. This statute legally obligates employers to withhold federal income tax, Social Security tax, and Medicare tax from wages. The IRS uses the W-4 to determine the correct withholding amount based on an employee's filing status, dependents, and other adjustments. While Detroit itself may not have a local ordinance specifically for the W-4, the city's business licensing and revenue division enforces federal and state tax compliance as a condition of operation. Without a valid W-4 for each employee, your business cannot accurately calculate and remit payroll taxes.
The consequences of failing to secure and use accurate W-4s are severe and costly. Since incorrect withholding leads to tax underpayments, the IRS holds the employer, not the employee, primarily responsible for errors and penalties. These are the primary risks:
- Failure-to-file penalties: The IRS can assess a penalty of 5% of the unpaid tax liability per month, up to a maximum of 25%.
- Failure-to-pay penalties: A separate penalty of 0.5% per month applies to any unpaid tax balance.
- Interest accrual: Interest compounds daily on any unpaid penalties and taxes from the due date.
- Criminal prosecution: For cases of willful tax evasion or fraud, employers face potential fines and imprisonment.
- Business disruption: An IRS audit can freeze operations, trigger back-tax assessments, and delay or jeopardize renewal of your local Detroit business licenses.
Legal code: Internal Revenue Code (Title 26)
Recent update: For the 2026 tax year, the IRS released a revised Form W-4 to further simplify the withholding calculation process, and all employers must use the most current version.

40 of 48 auto-filledFiling Status: Head of Household
checkboxCheck this box if you meet the IRS definition of Head of Household for federal tax purposes—specifically, if you are unmarried, paid more than half the cost of keeping up a home for the year, and have a qualifying person living with you.
COMMON MISTAKE: Commonly checked incorrectly by single parents who share custody; the parent who has the child for more nights during the year typically qualifies, per IRS Publication 501.
Filing Status: Married Filing Jointly or Qualifying Surviving Spouse
checkboxCheck this box if you are legally married as of the last day of the tax year and are filing a joint return with your spouse, or if you are a widow(er) with a dependent child and qualify as a surviving spouse for the two years following your spouse's death.
COMMON MISTAKE: Selecting this status when your spouse passed away earlier in the year and you do not have a dependent child, which does not meet the 'qualifying surviving spouse' criteria.
Filing Status: Single or Married Filing Separately
checkboxCheck this box if you are unmarried, divorced, or legally separated as of the last day of the tax year, or if you are married but choose to file a separate return from your spouse.
COMMON MISTAKE: A married employee checking this box because they are separated but not legally divorced, which can lead to incorrect withholding and a potential tax bill.
First Name and Middle Initial
textEnter your legal first name as it appears on your Social Security card, followed by a space and your middle initial if you have one; do not include suffixes like Jr. or Sr.
COMMON MISTAKE: Using a nickname or abbreviated name (e.g., 'Mike' instead of 'Michael') or including a period after the initial, which can cause a mismatch with SSA records.
Last Name
textEnter your legal last name (surname) exactly as it appears on your Social Security card, including hyphens or spaces if applicable.
COMMON MISTAKE: Omitting a hyphenated last name (e.g., entering 'Smith' instead of 'Smith-Jones') or including a maiden name not yet updated with the Social Security Administration.
Street Address
textEnter the street number and name of your current residential address where you receive mail, including apartment or unit number if applicable.
COMMON MISTAKE: Entering a business/P.O. box address, which is not acceptable for this form, or using an outdated address that does not match other tax records.
City, State, and ZIP Code
textEnter the city, two-letter state abbreviation, and full five or nine-digit ZIP Code that corresponds to the street address entered in the previous field.
COMMON MISTAKE: Using a non-standard state abbreviation (e.g., 'Mich.' instead of 'MI') or an incorrect ZIP Code that doesn't match the city, which can delay IRS correspondence.
Social Security Number
textEnter your nine-digit Social Security Number (SSN) in the format XXX-XX-XXXX, without spaces, exactly as issued by the Social Security Administration.
COMMON MISTAKE: Transposing digits, omitting a digit, or entering an Individual Taxpayer Identification Number (ITIN) instead of an SSN, which will cause the employer's payroll submission to be rejected.
Step 2(c): Two Jobs Checkbox Option
checkboxCheck this box if you (or your spouse if filing jointly) hold more than one job at the same time, which triggers the use of the Two-Earners/Multiple Jobs Worksheet on page 3 to calculate additional withholding.
COMMON MISTAKE: An employee with only one job checking this box, which will cause excessive withholding and a significantly smaller paycheck, often leading to a request for a corrected W-4.
Step 3(a): Child Tax Credit Amount
textEnter the total dollar amount from the Child Tax Credit and Credit for Other Dependents calculated using the worksheet on page 3, based on the number and status of your qualifying dependents.
COMMON MISTAKE: Entering the number of children instead of the dollar amount, or including ineligible dependents, which results in incorrect withholding and a potential tax liability or penalty.

Top 5 Employee's Withholding Certificate Mistakes
1. Using the Outdated or Incorrect Form Version
Submitting Form W-4 (2023) instead of the current Form W-4 (2026) is a top rejection cause. The IRS updates withholding formulas and allowances, and older versions are flagged by payroll systems. Using an outdated form adds 1-2 payroll cycles to your correction timeline, as you must re-process your employee's withholding from the effective date.
2. Inaccurate Marital Status or Multiple Jobs Selections
Selecting 'Single or Married filing separately' when the employee is the sole earner in a married household leads to over-withholding and reduced take-home pay. Conversely, incorrectly checking 'Multiple Jobs' when an employee works two part-time jobs for the same employer (like you) causes severe under-withholding and a large tax bill. This mistake is the #1 cause of IRS penalty assessments against employees for underpayment.
3. Blank or Invalid Social Security Number (SSN)
Leaving the SSN field blank or entering a number with dashes (e.g., 123-45-6789) instead of just the 9 digits (123456789) will cause immediate system rejection by the IRS and your payroll software. Your employee's wages cannot be posted correctly without a valid, properly formatted SSN. This mistake adds a week of delay as you must contact the employee for a corrected form.

Gather Required Employee Information
Collect accurate personal details for each employee: full legal name, Social Security Number (SSN), address, and filing status (Single, Married, etc.). For new hires, this is done as part of the onboarding I-9 process. The most common error is transposing SSN digits or using a nickname instead of a legal name, which will cause payroll processing errors and potential IRS mismatches. Have employees complete a paper or digital Form W-4 during their first shift.
Complete the Federal Form W-4
Using the 2026 version of IRS Form W-4, fill out Sections 1 (employee personal information) and 5 (signature). Michigan does not have a separate state withholding form; the federal W-4 is used for both. For employees claiming exemptions from withholding (Step 4(c)), you must have a valid withholding exemption certificate from the Michigan Department of Treasury (Form MI-W4, now obsolete, but exemptions must be documented). Ensure the employee's signature and date are present—unsigned forms are invalid.
Implement Withholding in Your Payroll System
Enter the data from the completed W-4 into your payroll software or service (e.g., Gusto, ADP, QuickBooks Payroll). Accurately input the filing status, number of dependents for the credit (Step 3), and any additional withholding requested (Step 4). This step is where most calculation errors occur—double-check that the system's tax tables are updated for 2026. You are required to keep each employee's W-4 on file for at least four years after the date the tax becomes due or is paid, whichever is later.

See All RequirementsProcessing timelines vary significantly depending on your submission method and the Michigan Department of Treasury's current caseload, as posted on their application guide. Submitting the Michigan Employee's Withholding Exemption Certificate (Form MI-W4) by mail typically takes 4–6 weeks, while filing electronically can reduce this to 2–3 weeks. The final issuance is often tied to the processing of your Business License (Restaurant), as the city requires valid state tax withholding registration before finalizing local licenses.
The state of Michigan does not charge a government filing fee for submitting the Employee's Withholding Exemption Certificate (Form MI-W4). Per the Michigan Department of Treasury fee schedule, the form itself is free to obtain and file. However, failure to properly register can lead to penalties for late withholding payments, which are calculated as a percentage of the unpaid tax plus interest. Not legal advice — verify with the Michigan Department of Treasury.
No, you cannot transfer an employee's withholding certificate. The withholding certificate (MI-W4) is tied to an individual employee's tax status, not a business location. If you move your restaurant to a new address within Detroit, you must update your business address directly with the Michigan Department of Treasury and the City of Detroit, which often triggers a need for an updated City Business License/Registration. Contact the Michigan Department of Treasury to confirm the specific process for updating your business's withholding account address.
There is no formal renewal for an employee's withholding certificate (MI-W4). Each employee's certificate remains in effect until they submit a new one. Michigan law (under the Income Tax Act) requires employers to have a current MI-W4 on file for every employee, and employees must submit a new form whenever their personal exemption allowances change. Employers must retain these certificates for at least four years, as required for audit purposes by the Michigan Department of Treasury.
There is typically no physical inspection for the Employee's Withholding Certificate. Compliance is verified through audits of your payroll records and quarterly wage reports (Form MI-941). During an audit by the Michigan Department of Treasury, you will need to produce all employee MI-W4 forms to prove correct withholding calculations. Failure to maintain these records can result in fines and a requirement to pay back taxes, plus interest. Ensuring your payroll system is set up correctly from the start is crucial, similar to the process for obtaining your federal Application for Employer Identification Number.
