Federal W-4 & payroll deductions

W-4 Step 2 checkbox is checked

2020-or-later W-4 only. Benefits must already qualify under your employer plan; this tool does not determine contribution eligibility or annual limits.

Louisiana state form — review defaults

L-4 line 7: signed adjustment ($)

L-4 deduction code

I have a valid exemption from this state’s income withholding

Local payroll charges — not confirmed

Check your paystub for local or other employee payroll charges not already entered as benefits or after-tax deductions.

Ask your employer: “Are any local or other payroll charges missing from this breakdown, and how much applies to this paycheck?” If you do not know, leave the confirmation unchecked. Where local confirmation is required, the result stays partial.

Local / other charges this paycheck ($)

Enter a confirmed dollar amount, including 0 if payroll confirms none. Changing this amount clears confirmation.

I checked with payroll or my paystub: this local amount is correct

Use each deduction once. Do not repeat amounts entered under benefits or after-tax deductions.

Estimates only. Annual salary assumes equal regular paychecks. Variable pay, tips, multiple employers and nonresident-alien rules require separate review.

Calculated in your browser. No salary entries saved or transmitted by this tool.

How Louisiana withholding is handled

Louisiana uses a payroll withholding rate and L-4 deduction codes. The payroll deduction is not necessarily the final annual-return deduction.

A state withholding example

Weekly taxable pay $700 with L-4 code 1 gives $13.98 state withholding before the signed adjustment.

Coverage limits

L-4 line 7 can increase or decrease withholding. A missing certificate uses code 0; negative final withholding is floored at zero.

Regular resident W-2 wages only. Use confirmed local/other payroll charges where required. No tax-return, reciprocity, nonresident-alien or special-occupation calculations. Benefit entries must qualify under your employer’s plan.
