Get your taxes done using TurboTax

You got it, but beware payment timing.  To see this calculation see lines 1-9 of Form 2210.

 

In your situation with significant increase in tax from year to year you can pay estimated tax based on prior year tax.  The only variable from 2025 that matters in that case is any withholding.  But the tax has to be paid "timely" - quarterly for estimated taxes; withholding is regarded as timely by default (the total is divided by 4).  When you filed for 2024 using TT it would have generated ES vouchers by default based on prior year tax and assuming 2025 withholding will be the same as 2024.

 

Subtract your estimated withholding from the 132k and divide what is left by 4, that's the quarterly payment you need to make / should have made.  If you didn't pay this in Q1 and Q2 you will be accruing penalty but you can stop the penalty growing if you pay that in Q3 i.e. by Q3 deadline you need to have paid 75% of that annual ES total and the remaining 25% in January 2026, and the balance due on your return in April 2026.

 

The penalty rate is 8% annually, but would be applied on 25% of the missed ES since Q1 for a few months until you pay it, 25% of the missed ES since Q2, so the penalty is probably not too bad as long as you get the ES caught up.

 

You can also increase withholding to meet more of what is due during the year and reduce the portion due from estimated tax payments, but you only only 6 months left for that to apply.
