What are the quarterly tax dates for 2025?
If you’re self-employed, a freelancer, travel nurse, or a small business owner, you’re likely required to pay estimated quarterly taxes. Here are the IRS deadlines for the 2025 tax year:
- April 15, 2025 – First-quarter payment due.
- June 17, 2025 – Second-quarter payment due.
- September 16, 2025 – Third-quarter payment due.
- January 15, 2026 – Fourth-quarter payment due (for income earned in the last quarter of 2025).
It’s important to meet these deadlines to avoid penalties for underpayment.
How to Calculate Quarterly Taxes:
To calculate your 2025 estimated taxes, follow these steps:
- Project your annual income – Include all sources such as freelance income, business revenue, or investment returns.
- Subtract eligible deductions and credits – Factor in retirement contributions, business expenses, and other applicable deductions.
- Use IRS Form 1040-ES – This form includes a worksheet and tax tables to help you determine the appropriate amount for each quarter.
- Submit payment online or by mail – IRS Direct Pay, EFTPS, and mailing with Form 1040-ES are all accepted methods.
If you’re unsure about your calculations or want to avoid overpaying or underpaying, consulting a CPA is recommended.
IRS Penalty Thresholds for 2025
| Criteria | Threshold for Avoiding Penalty |
| Pay 90% of 2025 taxes | Avoid penalty by paying at least 90% of total tax liability |
| Pay 100% of 2024 taxes | Avoid penalty if 100% of the previous year’s taxes are paid (110% for high-income individuals) |
Why Compliance Matters
Paying estimated taxes isn’t optional for those with untaxed income streams. Failing to comply can result in:
- Monthly penalties and interest charges
- Reduced cash flow due to unexpected tax bills
- Red flags in your IRS profile increasing audit risk
Staying compliant shows fiscal responsibility and prevents year-end financial strain.
3 Common Mistakes and How to Avoid Them
3. Underestimating Income
Be conservative in your deductions and realistic with income projections. Use rolling updates each quarter to adjust.
2. Not Adjusting Payments
Quarterly payments should reflect actual income. If your revenue increases or drops, adjust the next quarter’s payment accordingly.
3. Missing Deadlines
Mark all due dates on your calendar, or set automated reminders. Using a tax professional ensures deadlines aren’t missed.
Strategies for Staying on Track
- Use bookkeeping software to keep records up-to-date and make accurate projections.
- Set aside taxes monthly – treat it like a fixed business expense.
- Schedule quarterly check-ins with your CPA to adjust for any financial changes.
- Review and revise Form 1040-ES each quarter as your situation evolves.
When to Involve a CPA
Working with a CPA is especially helpful if you:
- Have fluctuating or high income
- Operate in multiple states or countries
- Receive income from multiple sources
- Manage stock options or investment portfolios
A CPA can provide customized advice, ensure accurate calculations, and help you plan tax strategies aligned with business goals.
