Estimated Tax Payments for S Corporations

An S corporation must make quarterly estimated tax payments if the sum of the following estimated taxes, less any credits allowed against the tax, is $500 or more:

• S corporation taxes
• Minimum fee
• Nonresident withholding
• Composite income tax

The S corporation must pay quarterly installments based on its required annual payment. The annual payment amount is equal to the S corporation’s total tax liability for the prior tax year or 90% of all the taxes listed, less any credits allowed against the tax for the current tax year (whichever is less).

Note: Estimated payments are not required the first year an S corporation is subject to tax in Minnesota.
