Quarterly Estimated Tax Payments for H-1B Visa Holders

Employer withholding only covers wages. If you have RSU income, Indian investment income, or a spouse earning on H-4 EAD, you likely need to make quarterly estimated payments — or face an underpayment penalty that accrues throughout the year.

Who Needs to Make Estimated Payments

You generally need to make estimated tax payments if you expect to owe at least $1,000 in federal tax for the year after subtracting withholding and refundable credits, and your withholding and credits will cover less than:

• 90% of your current year tax liability, or
• 100% of your prior year tax liability (110% if prior-year AGI exceeded $150,000)

For most H-1B holders, estimated payments become relevant in one or more of these situations:

• RSU vesting. Your employer withholds at 22% (supplemental rate), but if you are in the 32% or 35% bracket, the gap between withheld and owed can be $10,000+ on a single vesting event.
• Indian investment income. Dividends from NRO accounts, interest from NRE savings (once you are a US tax resident), and gains from Indian equity or mutual fund sales carry zero US withholding.
• Indian rental income. Rent collected from property in India flows to Schedule E and is taxed as US ordinary income. No withholding occurs.
• H-4 EAD self-employment. A spouse earning consulting or freelance income on H-4 EAD has no employer and no withholding. Every dollar of SE income creates a combined self-employment and income tax liability that must be prepaid quarterly.
• 1099-NEC side income. Technology professionals who consult or do contract work on the side receive 1099-NEC forms with no tax withheld. Note that H-1B holders must comply with USCIS employment authorization rules — work outside your H-1B petition employer may require separate authorization.

The Four Payment Deadlines

Estimated payments are made using Form 1040-ES vouchers or electronically through IRS Direct Pay or EFTPS. The due dates for tax year 2026 are:

Notice that Q2 covers only two months (April and May), while Q4 covers four months. The uneven periods exist because the original due dates were designed around agricultural income cycles and have never been updated. The practical implication: you cannot skip Q2 just because it feels like a short window.

If a due date falls on a weekend or federal holiday, it shifts to the next business day. For example, if June 15 falls on a weekend, the due date shifts to the following Monday.

How Much to Pay Each Quarter

There are two main strategies for computing each quarterly payment:

How to Make the Payments

There are four ways to pay estimated taxes. All are legitimate; the electronic methods are fastest and provide instant confirmation:

1. IRS Direct Pay (irs.gov/payments/direct-pay). Free. Pulls directly from a US bank account. You select "Estimated Tax" as the payment type and enter the tax year. No registration required for one-off payments. Confirmation number is your proof.
2. EFTPS (Electronic Federal Tax Payment System). Free. Requires upfront registration (takes a few days). Lets you schedule payments in advance — useful for setting up all four quarterly payments at once at the start of the year.
3. IRS2Go app. Mobile interface to Direct Pay. Useful for last-minute same-day payments from a phone.
4. Form 1040-ES paper voucher with check. Mail a check with the appropriate quarterly voucher. Considered paid on the postmark date. Slower and harder to confirm receipt — not recommended.

Do not pay through third-party services that charge a convenience fee unless you specifically need to pay by credit card (the IRS charges up to 1.87% for credit card payments through authorized processors). For bank transfers, IRS Direct Pay is always free.

State Estimated Taxes

Federal estimated payments only cover your IRS obligation. Most states that have income taxes (California, New York, Texas has none, etc.) have parallel quarterly estimated payment requirements. California, for example, uses a 30/40/0/30 split across four quarters — not the even 25% split the IRS uses.

If you live in a high-income-tax state like California (13.3% top marginal rate) or New York City (combines state and city to over 12%), the state estimated payment requirement can be as large as the federal one. Check your state revenue department's requirements separately — state penalties for underpayment are calculated independently from the federal Form 2210 penalty.

Common Mistakes

1. Treating W-2 withholding as covering all income. Employer withholding only applies to wages. RSU proceeds, broker dividends, and Indian investment income are not covered.
2. Paying one lump sum in January instead of quarterly. A single large payment in January (the Q4 due date) eliminates the Q4 underpayment but does nothing for Q1–Q3 penalties already accrued during the year.
3. Forgetting the 110% threshold. The prior-year safe harbor is 100% only if your prior-year AGI was $150,000 or below. At $151,000 AGI last year, you need 110% to be safe.
4. Not updating estimates after a large mid-year RSU vesting. If a big vest happens in August, you still have Q3 (September 15) and Q4 (January 15) payments available. Increase those payments to catch up.
5. Skipping state estimated payments while covering federal. The IRS and your state tax authority are separate. Covering your federal obligation does not satisfy state requirements.

How Our Platform Handles This

H1B TaxFile calculates your estimated payment obligations as part of the filing process:

• After entering your income, withholding, and prior-year tax, the platform computes the required quarterly payments under both the prior-year safe harbor and the 90% current-year method.
• For H-1B holders with RSU income, the platform flags whether your employer's withholding at 22% covers your actual marginal rate, and estimates the quarterly payment needed to close the gap.
• If you underpaid during the year, the Form 2210 underpayment penalty is automatically calculated and added to Line 38 of your Form 1040.
• The platform generates a worksheet with estimated payment amounts and due dates for the upcoming year, so you can plan ahead after filing.
