New Mexico uses federal exemptions for state withholding calculations. Since a state tax certificate is not required, the allowance structure follows the federal W-4 system. Employees typically claim allowances for themselves, spouse (if filing jointly), and dependents based on federal rules.
| Component | Allowances | Notes |
|---|---|---|
| Yourself | 1 allowance | Based on federal W-4 |
| Spouse | 1 allowance | If filing jointly (based on federal W-4) |
| Each Dependent | 1 allowance | Per dependent (based on federal W-4) |
Total Allowances = Federal W-4 Allowances
New Mexico uses federal exemptions directly, so no separate state form is required. The allowance count matches the federal W-4 allowances.
