June 15 Tax Deadline: Q2 Estimated Taxes & PTE Payments Explained

If you own a business or work for yourself, June 15 isn't just another day on the calendar. It's the deadline for your Q2 estimated tax payment — and missing it can cost you more than you'd expect.

What Are Estimated Taxes?

When you're self-employed or run a business that doesn't withhold federal taxes from a paycheck, the IRS expects you to pay taxes throughout the year — not just at filing time. These are called estimated tax payments, and they're due four times a year. The Q2 payment covers income earned from April 1 through May 31, and it's due on June 15. Who needs to pay? • Self-employed individuals and freelancers • Sole proprietors • Partners in a partnership • S-Corp shareholders who receive distributions • Anyone who expects to owe $1,000 or more in federal taxes after withholding

What Happens If You Miss the Deadline?

The IRS doesn't wait until you file your return to charge you. If your Q2 payment is late — or not enough — you'll be charged interest and an underpayment penalty starting from the due date. That charge applies even if you pay your full balance when you file. The good news: there are safe harbor rules that protect you from penalties if your payments meet certain thresholds based on last year's tax liability or this year's projected income.

What Is the PTE Tax Election — and Why Should You Care?

If your business is an S-Corporation or Partnership, this section is especially relevant. Several states — including California — allow businesses to make a Pass-Through Entity (PTE) tax election. Instead of the individual owners paying state income tax on their share of business income, the business pays the tax at the entity level. Why does that matter? Because the SALT deduction cap (the $10,000 limit on state and local tax deductions on your federal return) doesn't apply to taxes paid by the business itself. This means the PTE election can effectively allow business owners to deduct more state taxes on their federal return — reducing their overall tax bill. But there's a catch: PTE payments are typically tied to specific deadlines, and in California, an installment payment is due in June. Missing it can limit or eliminate the benefit for the year.

How Do You Know If You've Paid Enough?

This is where it gets specific to your situation. Your Q2 payment amount depends on: • Your projected net income for the year • How much you've already paid in Q1 • Whether you're using the annualized income method or the prior-year safe harbor • Your state's requirements on top of federal There's no one-size-fits-all number, which is exactly why it pays to have someone run the calculation for you before the deadline — not after.

What Should You Do Before June 15?

1. Check whether you've made your Q1 payment and how much it was 2. Estimate your Q2 net income 3. If you own an S-Corp or Partnership, ask whether a PTE election makes sense for your state 4. Make your payment through IRS Direct Pay or EFTPS for federal, and your state's payment portal for state If you're not sure where to start — or you're worried you've underpaid — now is the time to get a second opinion.
