Overview of Federal Withholding and Estimated Tax for Individuals

Immigrant workers across the United States 🇺🇸 are heading into year-end with a familiar question: how much federal income tax should they pay now to avoid a surprise bill later?

The IRS runs a pay-as-you-go system, meaning people must pay tax during the year as they earn income—mainly through two channels: withholding from pay and estimated tax for income that isn’t subject to withholding. The choice matters. Paying too little during the year can bring penalties and interest, even if a refund is due at filing time.

According to analysis by VisaVerge.com, newcomers tend to be hit hardest by these rules because U.S. payroll and quarterly payment schedules differ from systems many migrants knew before they arrived.

Policy basics: withholding versus estimated tax

With withholding, an employer or payer takes federal income tax from each paycheck or periodic payment and sends it to the IRS for you.

• Employees tell their employer how much to withhold by filing Form W-4—the Employee’s Withholding Certificate.
• The current Form W-4 no longer uses “allowances.” Instead, it asks for information such as filing status, other income, deductions, and any extra amount you want withheld.
• You can submit a new Form W-4 any time to adjust your withholding after life changes (marriage, second job, large investment income).

The IRS explains the pay-as-you-go system in detail in Publication 505:
– About Publication 505: https://www.irs.gov/forms-pubs/about-publication-505

Some non-wage payments also allow withholding:
– Pensions and annuities (including commercial annuities) use Form W-4P—the Withholding Certificate for Pension or Annuity Payments.
– Form W-4P lets you choose withholding, opt out, or add extra withholding.
– The payer does not send Form W-4P to the IRS unless the IRS asks in writing.
– Withholding may also apply to bonuses, commissions, and gambling winnings.

Estimated tax — who must pay and when

Income usually not covered by withholding—dividends, interest, capital gains, rent, royalties, and self-employment—falls under the estimated tax system.

You’re generally required to make quarterly estimated payments if:
– You expect to owe at least $1,000 in tax for the year after subtracting withholding and credits, and
– Your withholding and credits are less than the smaller of:
1. 90% of this year’s tax, or
2. 100% of last year’s tax (or 110% if your adjusted gross income was more than $150,000)

Individuals make these payments using Form 1040-ES:
– Form 1040-ES: https://www.irs.gov/forms-pubs/about-form-1040-es

Example of the prior-year safe harbor:
– Jason earns $130,000 and his tax for the current year is $10,000 (double the prior year).
– He can avoid a penalty if his combined payments are at least $5,000 (100% of last year’s tax).

Deadlines, penalties, and waiver options

Estimated tax due dates (fixed by period):
1. Income Jan. 1–Mar. 31: due April 15
2. Income Apr. 1–May 31: due June 15
3. Income Jun. 1–Aug. 31: due September 15
4. Income Sep. 1–Dec. 31: due January 15 of the next year

• If a due date falls on a weekend or legal holiday, it moves to the next business day.
• Key exception: the January 15 payment is not required if you file Form 1040 and pay the full tax you owe by January 31.

Real-world timing examples:
– Janet made no estimated tax payments in 20X1. She files and pays the balance on January 26, 20X2. Her fourth-period payment is considered on time, but she may owe penalties for missing the first three periods. Any penalty will be calculated up to January 26, 20X2.
– Margaret sold an investment property in July and estimates owing $25,000. Because she had no tax liability the prior year, she isn’t required to make estimated payments for that year under IRS rules; her first payment (if required) would be due by September 15.

The IRS may charge a penalty even when you get a refund—what matters is whether you paid enough tax during the year by each period’s deadline. Non-business taxpayers send quarterly amounts using Form 1040-ES vouchers or electronic payments. If you fall short, penalties are based on how much you underpaid and when you paid.

Waiver paths for penalties

You can request that the IRS waive the penalty via two paths:
– Complete waiver: Ask the IRS to calculate the penalty for you.
– Partial waiver: You calculate the penalty using Form 2210 and attach it to your return.

• Whether seeking a full or partial waiver, file your return on time and pay as much as you can to limit extra charges.
• Form 2210: https://www.irs.gov/forms-pubs/about-form-2210

Practical planning tips for newcomers, families, and retirees

The difference between withholding and estimated tax often turns on how income arrives:

• Wage earners in sponsored roles typically rely on payroll withholding and a correctly completed Form W-4.
• Contractors, rideshare drivers, small business owners, and investors need to plan for estimated payments, sometimes starting midyear.
• Mixed households (one spouse on payroll, the other self-employed) can:
  • Increase withholding on the wage earner’s Form W-4 to cover both spouses’ tax, or
  • Make quarterly estimated tax payments for the self-employed side.

Practical steps:
– Review your Form W-4 after major changes—new job, second job, marriage, or a year with large investment gains—so your withholding matches your situation.
– Form W-4: https://www.irs.gov/forms-pubs/about-form-w-4
– If you receive a pension or annuity, use Form W-4P to set withholding or opt out; be aware that opting out may require quarterly estimated tax payments.
– Form W-4P: https://www.irs.gov/forms-pubs/about-form-w-4p
– Mark the four standard quarterly due dates on your calendar. If you plan to file and pay the full balance by January 31, you can skip the January 15 estimated payment.
– Use the safe harbors to reduce penalty risk:
– Pay at least 90% of this year’s tax, or
– 100% of last year’s tax (110% if AGI > $150,000).
– Keep records of payments and IRS confirmations—penalties depend on timing, so proof of dates matters.

Additional clarifications from current IRS practice

• The Form W-4 design changed in recent years to gather simple, actionable data (filing status, adjustments, deductions, extra amounts) instead of the old “allowances.”
• Pensioners and annuitants may choose no withholding on Form W-4P, but that does not eliminate the tax bill—estimated tax may still be required.
• The payer does not send Form W-4P to the IRS unless there’s a written request from the agency.

No matter your visa type or long-term plan, U.S. tax law follows you while you live and work here. The system is designed so the IRS receives tax steadily, not just at filing time. That’s why penalties can apply even if you receive a refund at year-end.

– Employee withholding choices: Form W-4 — https://www.irs.gov/forms-pubs/about-form-w-4

The core message remains steady: pay during the year, by the set dates, and in the right amounts. If your taxes come mainly from wages, keep your Form W-4 current. If you earn from dividends, interest, capital gains, rent, royalties, or self-employment, plan for quarterly estimated tax. If you do both, use either route—or both—to stay on track and avoid surprises at filing time.
