IRS Notice 940 Spanish – In today’s complex tax landscape, understanding your withholding obligations is crucial for avoiding surprises during tax season. If you’re a Spanish-speaking taxpayer or employer, IRS Notice 940 (SP), titled “¿Por qué tengo que entregarle un Formulario W-4 a mi empleador?” provides essential guidance on why employees must submit Form W-4 to their employers. This notice, revised in August 2024, helps clarify the process of federal income tax withholding and ensures you’re not overpaying or underpaying taxes. Whether you’re starting a new job, experiencing life changes, or simply want more accurate withholding, this article breaks down the key details from trusted IRS sources to help you stay compliant and informed.
What Is IRS Notice 940 (SP) and Its Purpose?
IRS Notice 940 (SP) is a Spanish-language document designed to explain the importance of completing and submitting Form W-4 (or its Spanish equivalent, Form W-4 (SP)) to your employer. Released by the Department of the Treasury and the Internal Revenue Service, this notice aims to inform employees about federal income tax payments, withholding procedures, and how to avoid penalties or excessive refunds.
The primary purpose is to address common questions like:
- Why pay federal income tax as you earn?
- How does withholding work?
- What happens if you don’t submit a properly completed Form W-4?
According to the notice, federal income tax must be paid as income is earned, not just at year-end. Your employer withholds taxes from each paycheck and sends them to the IRS on your behalf. This “pay-as-you-go” system helps you cover most or all of your tax liability throughout the year, reducing the risk of owing a large sum when filing your return.

Why Do Employees Have to File Form W-4?
Form W-4, Employee’s Withholding Certificate, is a mandatory form for new hires and should be updated whenever your personal or financial situation changes—such as marriage, having a child, or a shift in income. Here’s why it’s required:
1. Accurate Tax Withholding
Without a completed Form W-4, your employer will withhold taxes as if you’re single with no deductions or credits, which could lead to overwithholding (a big refund but lost opportunity for interest) or underwithholding (owing taxes plus penalties). The notice emphasizes that overwithholding isn’t ideal because the IRS doesn’t pay interest on excess amounts, making it a poor savings strategy.
2. Accounting for Taxable Income
All wages, salaries, tips, and self-employment income are taxable. However, you can reduce your taxable income through adjustments, the standard deduction, or itemized deductions. Form W-4 helps calculate these to determine the right withholding amount. For detailed explanations, refer to IRS Publication 17 (SP), “El Impuesto Federal sobre los Ingresos.”
3. Handling Non-Wage Income
If you have income from dividends, capital gains, pensions, or other sources, the notice advises considering estimated tax payments via Form 1040-ES to avoid underpayment penalties. For pension income, use Form W-4P to adjust withholding.
4. Special Cases: Multiple Jobs or Exemptions
If you have multiple jobs or a working spouse, use the Multiple Jobs Worksheet in Form W-4 to allocate deductions accurately—typically claiming them on the highest-paying job’s form. You can also request no withholding if you had no tax liability last year and expect none this year, but this exemption must be renewed annually.
Nonresident aliens should consult Notice 1392 for supplemental instructions.
How to Complete Form W-4 (SP): Step-by-Step Guide?
Filling out Form W-4 (SP) is straightforward with the included worksheets and tax tables. Here’s a simplified process based on IRS guidance:
- Gather Information: Provide your name, Social Security number, address, and filing status (single, married, etc.).
- Calculate Deductions and Credits: Use worksheets for child tax credits, other dependents, itemized deductions, or income adjustments.
- Account for Multiple Jobs: Complete the Multiple Jobs Worksheet if applicable.
- Specify Additional Withholding: Enter any extra amount you want withheld per paycheck.
- Sign and Submit: Date the form and give it to your employer.
For precision, use the IRS Tax Withholding Estimator at IRS.gov/W4AppSP. Employers can use substitute forms, but they must match the official version’s instructions.
If your situation is complex (e.g., part-year employment or non-wage income), the estimator can help avoid under- or over-withholding.
Common Mistakes to Avoid When Filing Form W-4
- Not Updating Annually: Life changes like divorce or new dependents require a new form.
- Ignoring Estimated Taxes: For self-employment or investment income, don’t rely solely on withholding.
- Claiming Exemption Incorrectly: Only valid if you meet strict no-liability criteria; otherwise, taxes will be withheld as single.
- Using Employee-Created Forms: Employers won’t accept them—stick to official or approved substitutes.
Review your withholding mid-year by comparing year-to-date amounts to your estimated tax liability using Publication 505.
Additional Resources for Spanish-Speaking Taxpayers
The IRS offers Spanish versions of many forms, including Form 940 (SP) for employers’ FUTA tax returns, though unrelated to W-4 withholding. For broader employment tax info, see Publication 15 (Circular E) or visit IRS.gov/Espanol.
If eligible, check the Earned Income Credit (EIC) via Publication 596—it’s a refundable credit that can boost your return.
