Sometimes, an S corporation must make estimated tax payments.

Generally, an S corporation must make installment payments of estimated tax for the following taxes if the total of these taxes is $500 or more:

Partnerships file Form 1065, U.S. Return of Partnership Income to report income and expenses.
A partnership doesn't pay tax on its income, instead, it "passes through" any profits or losses to its partners. Generally, the partnership must prepare and give partners a copy of Schedule K-1 (Form 1065), Partner’s Share of Income, Deductions, Credits, etc., PDF or Schedule K-3 (Form 1065), Partner’s Share of Income, Deductions, Credits, etc. - International PDF.
The partners report the information from the K-1 or K-3 on their own returns and pay any taxes due, including estimated taxes.

How individual partners pay estimated tax - Because partners aren't employees of the partnership, partnerships don't withhold tax from their distributions to pay the partners' income and self-employment taxes shown on their Form 1040, U.S. Individual Income Tax Return or Form 1040-SR, U.S. Tax Return for Seniors. The partners may need to pay estimated tax payments using Form 1040-ES, Estimated Tax for Individuals.
As a partner, you can pay the estimated tax by:

Crediting an overpayment on your 2024 return to your 2025 estimated tax
Mailing a check or money order with a payment voucher from Form 1040-ES
Using Your online account
Using Direct Pay
Using EFTPS: The Electronic Federal Tax Payment System
Requesting an electronic funds withdrawal (EFW) if you're filing Form 1040 or Form 1040-SR electronically
