Which payments are still upcoming?
Tip: These will auto-toggle based on today’s date; you can adjust manually.
Notes: To generally avoid the underpayment penalty, pay the smaller of
90% of your 2025 tax or the safe harbor amount (100% of 2024 tax, or 110% if your 2024 AGI exceeded $150,000; $75,000 if MFS).
If you’ll owe less than $1,000 at filing, the penalty typically doesn’t apply.
