As a physician, your schedule leaves little room for tax planning. Between patient care, administrative responsibilities, and the demands of running or working within a practice, the IRS estimated tax payment schedule can slip off the radar. But the Q2 deadline, June 15, 2026, is one you do not want to miss.
This blog breaks down what estimated tax payments are, who needs to make them, how to calculate what you owe, and how to submit your payment before the deadline. For a broader overview, you can also review a complete tax filing checklist for physicians.
What Are Estimated Tax Payments?
Estimated tax payments are quarterly payments made to the IRS on income that does not have taxes automatically withheld. Unlike salaried employees whose employers deduct federal income tax from each paycheck, many physicians receive income that does not go through that same withholding process.
Estimated income tax is simply your projected federal (and sometimes state) tax liability for the year, paid in installments. The IRS generally requires you to make estimated tax payments if you expect to owe at least $1,000 in federal taxes after subtracting withholding and credits.
Who Needs to Pay It?
If you own a private practice, work as an independent contractor, earn income from investments, or receive partnership distributions, you are responsible for paying taxes on that income yourself throughout the year, rather than in one lump sum at filing time.
For physicians, this commonly applies when you are a sole proprietor or partner in a medical practice, working locum tenens or as an independent contractor, receiving dividend or investment income, earning rental income from real estate, or collecting any income not subject to employer withholding.
The IRS operates on a pay-as-you-go system. If you wait until April to pay everything at once, you may face underpayment penalties on top of the taxes you already owe.
Even attending physicians employed by a hospital can find themselves in this position if their investment portfolio or side income pushes their total tax liability past the threshold.
What Are the Due Dates for Estimated Tax Payments in 2026?
The estimated tax payment schedule follows four quarterly deadlines.
|
Quarter |
Income Period Covered |
Payment Due Date |
|
Q1 |
January 1 – March 31 | April 15, 2026 |
|
Q2 |
April 1 – May 31 |
June 15, 2026 |
|
Q3 |
June 1 – August 31 |
September 15, 2026 |
|
Q4 |
September 1 – December 31 |
January 15, 2027 |
The June 15 deadline is your Q2 payment. It may feel like it sneaks up quickly after Q1, partly because the Q2 income period is only two months long compared to the others.
What are the Methods for Calculating The Estimated Tax Payment for 2026?
There are two widely used approaches for calculating what you owe.
The first is the prior year safe harbor method. Under this approach, you base your payments on 100% of the tax you owed the prior year. If your adjusted gross income exceeded $150,000 in the prior year (or $75,000 if married filing separately), you must pay 110% of that prior year liability to qualify for the safe harbor protection. This method is predictable and protects you from underpayment penalties even if your income increases significantly.
The second is the current year actual income method. Here, you estimate your income, deductions, and credits for the current year and calculate 90% of your projected tax liability. Understanding how your tax bracket affects estimated tax payments can help you calculate more accurately. This method can reduce what you pay if your income this year is lower than last year, but it requires more careful tracking throughout the year.
For physicians with variable income, a combination of both methods often works best. This is exactly the kind of situation where working with a financial advisor familiar with physician finances makes a meaningful difference.
How to Make Estimated Tax Payments Online?
The IRS offers several ways to submit your Q2 payment before June 15.
IRS Direct Pay is the simplest option for most physicians. You can visit the IRS Direct Pay portal and make a payment directly from your bank account at no cost. You can schedule payments in advance, which is helpful if you want to set it and move on.
The Electronic Federal Tax Payment System, or EFTPS, is another option. It requires advance registration, so if you have not already enrolled, do so well before the June 15 deadline. EFTPS allows you to schedule and track all your estimated payments in one place.
You can also pay by mailing a check along with Form 1040-ES to the IRS. The mailing address depends on your state of residence, which is listed in the Form 1040-ES instructions.
Are Estimated Tax Payments Considered an Expense?
For individual filers, federal estimated tax payments are not deductible as a business expense. However, state and local estimated tax payments may be deductible on your federal return, subject to the SALT deduction cap. If you are filing as a business entity, the treatment can differ. This is one of the nuances that a financial advisor with physician-specific experience can help you get right.
What Happens If You Miss the June 15 Deadline?
Missing a quarterly deadline does not mean you are in serious trouble, but it does typically result in an underpayment penalty. Many physicians overlook key details that lead to penalties, including common tax filing mistakes that trigger IRS audits. The penalty is calculated based on the amount underpaid and how long it remained unpaid. The best course of action if you missed Q1 is to catch up as quickly as possible and ensure your Q2 payment covers the shortfall.
Tax planning for physicians is not straightforward. Between student loan repayment strategies, practice ownership decisions, investment income, and shifting income levels across different stages of a career, estimated taxes are just one piece of a much larger financial picture.
