A profitable C corporation may need to make estimated tax installments during the year. Waiting until the annual return is prepared can leave the business short of cash and expose it to an underpayment calculation.

Book profit and taxable income are not always identical. Depreciation, owner transactions, nondeductible costs, and other adjustments can change the projection. Use reconciled financial statements and update the estimate when results change materially.

Keep proof of each payment with the business tax records and verify the taxpayer identification number, tax period, and payment type. An owner payment on a personal return is not automatically a payment of the corporation's tax.

Your next steps

• Project corporate taxable income during the year.
• Track federal and state installments separately.
• Reconcile payment confirmations before filing.
