14 checks built for this form, so a wrong date or a missing answer is caught before anyone else sees it.
This check ensures that the Social Security Number entered in field 'textbox_0_7_bd9ebb47' is present and follows the standard 9-digit format (XXX-XX-XXXX or XXXXXXXXX). The SSN is critical for employee identification and tax reporting to the IRS. If the field is empty or the format is incorrect, the submission will be rejected, and the user will be prompted to enter a valid SSN.
This validation confirms that both the first name field ('textbox_0_0_5cc23924') and the last name field ('textbox_0_1_c618e98c') are filled out. A full name is legally required for employment records and tax documentation. A failure will prevent form submission and highlight the required name fields.
This check verifies that the employee's full address, including street ('textbox_0_2_1f833393'), city ('textbox_0_3_a2267c9f'), state ('textbox_0_4_bd1ddac2'), and ZIP code ('textbox_0_5_3c3842d2'), is provided. A complete address is necessary for mailing tax documents like the W-2 form. If any part of the address is missing, the form will be flagged as incomplete.
This check ensures the ZIP code entered in 'textbox_0_5_3c3842d2' is a valid 5-digit or 9-digit (ZIP+4) numeric format. An incorrect ZIP code can lead to misdirected mail and processing delays for important documents. Submissions with invalid formats will be rejected, requiring the user to correct the entry.
This validation ensures that exactly one filing status option ('choicebutton_0_22_49551f38', 'choicebutton_0_23_98d48af2', 'choicebutton_0_24_ee58fb4f') is selected. An employee must choose one and only one status as it is fundamental to calculating their tax withholding. If zero or more than one option is selected, an error is triggered, forcing a valid selection.
This check validates that the total dependent credit in 'textbox_0_10_9efada39' is the correct sum of the amount for qualifying children ('textbox_0_8_71d523a3') and the amount for other dependents ('textbox_0_9_c0f5dcd6'). This prevents mathematical errors that would lead to incorrect tax withholding. If the sum is incorrect, the system should flag the total field and may offer to auto-calculate the correct value.
