Frequently Asked Questions About Form DE 4

The Employee's Withholding Allowance Certificate (DE 4) form is used for California Personal Income Tax (PIT) withholding purposes only. It is used to compute the amount of taxes to be withheld from your wages by your employer to accurately reflect your state tax withholding obligation.

The DE 4 is used for California state income tax withholding, while the federal Form W-4 is used for federal income tax withholding only. Beginning January 1, 2020, the federal Form W-4 is used for federal income tax withholding only.

You may be fined $500 if you file a DE 4 that results in less tax being withheld than is properly allowable. Criminal penalties also apply for willfully supplying false or fraudulent information or failing to supply information requiring an increase in withholding.

You must consider your personal situation, including whether you claim allowances for dependents or blindness, whether you will itemize your deductions, and whether you have more than one income coming into the household. Use Worksheet A to determine your regular withholding allowances.

Yes, if you expect to itemize deductions, you can claim additional withholding allowances. Use Worksheet B to determine whether your expected estimated deductions may entitle you to claim one or more additional withholding allowances.

To qualify for the Head of Household filing status, you must be unmarried or legally separated from your spouse and pay more than 50% of the costs of maintaining a home for the entire year for yourself and your dependent(s) or other qualifying individuals.

Your withholding will usually be most accurate when all allowances are claimed on the DE 4 filed for the highest paying job and zero allowances are claimed for the others.

The Military Spouses Residency Relief Act allows certain military spouses to be exempt from California income tax withholding on their wages if they meet certain conditions, including their spouse being a member of the armed forces present in California in compliance with military orders, they are present in California solely to be with their spouse, and they maintain their domicile in another state.

You can visit the Franchise Tax Board (FTB) website for information on your last California Resident Income Tax Return (FTB Form 540).

The employee is responsible for providing proof that the correct California income tax withholding has been made. This means that the burden of proof rests with the employee to show the correct withholding amount.

For California Personal Income Tax (PIT) withholding purposes, registered domestic partners will be treated the same as spouses. This means that wages paid to registered domestic partners will be subject to the same tax withholding rules as wages paid to spouses. However, this law does not impact federal income tax law.

If you need assistance calculating your tax liability using Worksheet C, you should contact your employer to request the amount that will be withheld on your wages based on your marital status and the number of withholding allowances you will claim for 2024. Multiply the estimated amount to be withheld by the number of pay periods left in the year, and add the total to the amount already withheld for 2024.

If the amount withheld is less than your total tax liability, you may need to file quarterly estimates on Form 540-ES with the California Franchise Tax Board (FTB) to avoid a penalty. It's important to note that failure to make estimated tax payments on time can result in penalties and interest charges.

This validation is essential to ensure that the SSN is legitimate and belongs to the person in question. It helps in maintaining accurate tax records and preventing identity theft.
3
Address Completeness and Accuracy
Verifies that the address, including city, state, and ZIP code, is complete and accurately entered on the Employee's Withholding Allowance Certificate. This check is important for ensuring that all correspondence and tax documents reach the employee without delay. It also confirms that the address format conforms to postal standards.
4
Filing Status Selection
Checks that one filing status is selected on the form and that it is appropriate based on the personal information provided by the employee. This validation ensures that the employee's tax withholding is calculated correctly according to their marital status and other relevant factors. It also helps to prevent errors that could lead to incorrect tax calculations.
5
Allowances Claimed Verification
Validates that the number of allowances claimed on line 1c is the sum of lines 1a and 1b from Worksheet A and B on the Employee's Withholding Allowance Certificate. This check ensures that the employee's claimed allowances are calculated correctly, which directly affects the amount of tax withheld from their paycheck. It is a critical step in maintaining accurate tax withholding.
6
Confirms that the additional amount entered on line 2 for withholding is a valid numeric value
This validation check ensures that the value entered on line 2, which indicates the additional amount the employee wishes to withhold from each paycheck, is a numeric figure. It prevents the entry of non-numeric characters, which could lead to incorrect withholding amounts and potential issues with the employee's tax obligations. The check also verifies that the input is not negative, as withholding amounts cannot be less than zero. Additionally, it confirms that the field is not left blank if the employee has indicated a desire to withhold an additional amount.
7
Verifies that the exemption box on line 3 is checked only if the conditions for exemption for the year 2024 are met
This validation check verifies that the exemption box on line 3 is marked only if the employee fulfills all the conditions for exemption for the tax year 2024. It cross-references the employee's information with the criteria set by tax regulations to ensure eligibility. If the conditions are not met, the system alerts the user to correct the entry. This check is crucial to prevent claiming exemption improperly, which could result in penalties or owing back taxes.
8
Checks that the box on line 4 for exemption under the Service Member Civil Relief Act is checked only if applicable
This validation check scrutinizes the box on line 4, designated for service members claiming exemption under the Service Member Civil Relief Act. It confirms that this box is checked only if the employee is indeed a service member eligible for such an exemption. The check involves verifying the employee's service status and ensuring compliance with the Act's provisions. This prevents unauthorized claims of this exemption, which could lead to legal complications and the need for corrective actions.
9
Ensures that the form is signed and dated, certifying the accuracy of the information under penalty of perjury
This validation check ensures that the form has been duly signed and dated by the employee, which is a legal requirement for the form's validity. The signature certifies that the information provided is accurate and true to the best of the employee's knowledge, under penalty of perjury. The check confirms the presence of a signature and a date, and it may also verify the format of the date to ensure it is understandable and follows standard conventions. An unsigned or undated form cannot be processed and may lead to compliance issues.
10
Confirms that the employer's name and address are filled in the Employer's Section
This validation check confirms that the Employer's Section of the form contains the correct and complete name and address of the employer. It ensures that the information is present and formatted correctly, which is essential for proper identification and correspondence. The check may also involve verifying the accuracy of the address against official postal records. Incomplete or incorrect employer information can lead to misdirected documents and potential administrative difficulties.

Verifies that the California Employer Payroll Tax Account Number is entered and is valid

13
Ensures that if claiming exemption, the employee meets the exempt status and is prepared to provide proof if requested

14
Validates that if the employee expects to owe tax, a new DE 4 is submitted by December 1
Checks that employees who anticipate owing taxes have submitted a new DE 4 form by the specified deadline of December 1. This validation ensures compliance with tax filing requirements and helps employees avoid underpayment penalties. The system tracks the submission date and alerts the employee if a new form is due. This proactive measure assists in maintaining accurate tax withholding throughout the year.
15
Confirms that the tax tables for the year 2024 have been referenced if adjusting withholding or calculating additional tax
Ensures that any adjustments to withholding or calculations for additional tax are based on the correct tax tables for the year 2024.

This check is essential for aligning the employee's withholding with the current tax laws and avoiding discrepancies in tax payments.

Common Mistakes in Completing DE 4

One of the most crucial pieces of information on the Employee's Withholding Allowance Certificate (W-9) is the Social Security Number (SSN). Incorrectly entering this number can lead to potential tax issues and delays in processing. To avoid this mistake, double-check the SSN entered against the employee's original Social Security card or other official documentation. It is essential to ensure that all digits are entered correctly and in the correct order.

The Employee's Withholding Allowance Certificate must be signed and dated by the employee to be considered valid. Failing to do so can result in the form being rejected, causing delays in processing. To prevent this mistake, ensure that the employee signs and dates the form in the designated areas before submitting it.

Selecting an incorrect filing status can lead to incorrect withholding allowances and potential tax issues. It is essential to ensure that the employee selects the correct filing status based on their marital status and number of dependents. To avoid this mistake, review the instructions carefully and consult with the employee to ensure they have selected the correct filing status.

Entering an incorrect address or ZIP code on the Employee's Withholding Allowance Certificate can cause delays in processing and potential tax issues. It is crucial to ensure that the address and ZIP code entered are accurate and complete. To prevent this mistake, double-check the address and ZIP code against the employee's official documentation and ensure that all digits are entered correctly.

Claiming too many allowances or exemptions can result in insufficient withholding, leading to potential underpayment of taxes. It is essential to ensure that the employee claims the correct number of allowances or exemptions based on their situation. To avoid this mistake, review the instructions carefully and consult with the employee to ensure they have claimed the correct number of allowances or exemptions.

Failure to complete the appropriate worksheet (A, B, or C) on the Employee's Withholding Allowance Certificate (W-9) may result in incorrect withholding amounts. This could lead to underpayment or overpayment of taxes. To avoid this mistake, ensure you carefully read and follow the instructions provided in the form, and complete the required worksheet based on your filing status and income. If you are unsure which worksheet to use, consult the instructions or contact the IRS for assistance.

Leaving the employer's name and address blank on the W-9 form may delay or prevent the proper processing of your withholding allowance certificate. To avoid this mistake, double-check that you have entered the correct and complete employer information, including the name, address, and Employer Identification Number (EIN), if applicable. If you are unsure about the employer's information, contact them directly to confirm.

If you are a California resident or work in California, it is essential to provide the California Employer Payroll Tax Account Number on the W-9 form. Failing to do so may result in delays or issues with the processing of your withholding allowance certificate. To avoid this mistake, make sure you have the correct account number from your employer and enter it on the designated line of the form.

Withholding allowances may change from year to year based on tax tables and your filing status. Neglecting to adjust your withholding based on the new tax tables for the year 2024 could result in incorrect withholding amounts. To avoid this mistake, review the tax tables and instructions provided by the IRS and update your withholding allowances accordingly. If you are unsure about the correct withholding amount, consult a tax professional or the IRS for assistance.

If you are a military service member or a dependent, you may be eligible for exemption from withholding under the Service Member Civil Relief Act. Failing to provide proof of this exemption when required may result in unnecessary withholding. To avoid this mistake, make sure you have the required documentation, such as a Military Annual Tax Statement (Form 1099-MISC, Box 14) or a statement from your military personnel office, and submit it to your employer or the IRS as soon as possible.
