Pros: Simple, protects from penalties regardless of current year income Cons: May underpay if income increases significantly

Tip 3: Pay Early If You Have the Cash

There's no penalty for paying early or overpaying. If you have the money, pay ahead — the IRS will refund any overpayment when you file.

Tip 4: Use the Annualized Method for Variable Income

Tip 5: Don't Skip a Quarter

Even if money is tight, pay SOMETHING. Partial payments reduce penalties proportionally. Paying $2,000 instead of $7,500 is better than paying $0.

A Real Example

Sarah, a freelance designer earning $90,000/year:

• Schedules all four payments in January through EFTPS
• Each payment: $5,500 (safe harbor based on 2025 tax of $22,000)
• Total 2026 payments: $22,000
• Result: No penalties, peace of mind

Tom, a developer who "pays when he remembers":

• Missed Q1 deadline by 3 weeks
• Underpaid Q2 by $3,000
• Result: $780 in penalties by April

The 15-minute January setup saves hundreds in penalties and stress.

Q: How do I make a quarterly tax payment? Pay online at IRS.gov using Direct Pay, Electronic Federal Tax Payment System (EFTPS), or by mailing Form 1040-ES with a check. Direct Pay is the fastest and easiest method — no account needed, just bank information.

Q: What if I miss a quarterly tax deadline? The IRS charges an underpayment penalty of approximately 8% annualized on the unpaid amount. To avoid penalties, you must pay at least 90% of your current year tax or 100% of your prior year tax (110% if AGI exceeds $150,000) through withholding and estimated payments.

Calendar Reminder Strategy

The IRS does not send quarterly tax payment reminders. Missing a deadline triggers automatic penalties that accrue daily at approximately 8% annualized. Set up four recurring calendar alerts one week before each deadline: April 8, June 8, September 8, and January 8. Additionally, enroll in EFTPS (Electronic Federal Tax Payment System) for free, secure online payments with the ability to schedule payments up to 365 days in advance. This eliminates last-minute scrambling and ensures timely payments.

The Bottom Line

The quarterly tax deadlines for 2026 are April 15, June 15, September 15, and January 15. Mark these dates, set up a tax savings account, and use the safe harbor or annualized method to calculate payments.
