2025 Estimated Tax Payment Due Dates

2025 estimated tax payment due dates: Quarterly Due Dates: First Quarter (Jan-Mar 2025): Due April 15, 2025. Second Quarter (Apr-May 2025): Due June 16, 2025. Third Quarter (Jun-Aug 2025): Due September 15, 2025. Fourth Quarter (Sep-Dec 2025): Due January 15, 2026. Important Notes: Weekend/Holiday Rules: If due date falls on weekend or holiday, payment due next business day. Payment Methods: Online through EFTPS or IRS Direct Pay. By phone with bank account or credit card (fees apply). Mail with Form 1040-ES voucher. State Payments: Check state-specific due dates (may differ from federal). Planning Considerations: Prior Year Safe Harbor: Base 2025 payments on 2024 tax liability. Income Changes: Adjust payments if 2025 income differs significantly from 2024. Extension Impact: Filing extension doesn't extend estimated payment deadlines. Catch-Up Strategy: If behind on payments, can make larger payments in remaining quarters. Record Keeping: Maintain records of payment dates and amounts. Save confirmation numbers for electronic payments. Late Payments: Even one-day late payments may trigger underpayment penalties.
