Yes, C Corp taxes can vary by state. Different states have varying corporate tax rates, rules, and filing requirements. Some states may also impose additional taxes and fees.

To save on a C Corp tax return, consider:

  • Maximizing deductible business expenses.
  • Taking advantage of available tax credits.
  • Implementing tax-efficient strategies for income and dividend distribution.
  • Utilizing tax deferral options where applicable.
  • Engaging in strategic tax planning, like timing of income and deductions.
  • Consulting with a tax professional for tailored strategies and to stay compliant with changing tax laws and regulations.

This depends on various factors, including the specific financial circumstances of the business and its income levels. Generally, C Corps are subject to corporate income tax at the corporate level and shareholders also pay taxes on dividends at the individual level (double taxation). S Corps have pass-through taxation, meaning income is reported on the owners’ individual tax returns and taxed at their personal rates, avoiding double taxation.

In some cases, C Corps might pay more due to double taxation, but they also have tax benefits not available to S Corps. The more advantageous structure depends on the specific financial details and goals of the business.

Selling your C Corp entity affects your taxes in these ways:

Double Taxation: If your C Corp sells its assets, the corporation pays tax on any gains at the corporate level. Shareholders also pay taxes on any dividends or distributions received from the proceeds of the sale.

Capital Gains on Stock Sale: If shareholders sell their stock in the C Corp, they may incur capital gains tax on the difference between the sale price and their basis in the stock.

Asset Sale vs. Stock Sale: The tax implications can differ significantly based on whether the transaction is an asset sale or a stock sale. Asset sales may result in higher taxes due to corporate-level taxation followed by shareholder-level taxation upon distribution of proceeds.

State Taxes: Additional state taxes may apply depending on the state laws where your corporation operates.

What is a C Corporation?

A C corporation or C corp (named for being in subchapter ‘C’ of the Internal Revenue code) is a legal structure for a business entity that is separate from its owners or shareholders. C Corps offer limited liability protection and have a flexible ownership structure, allowing for an unlimited number of shareholders. Transferring or dividing ownership between shareholders is done through issuance of stock. This makes a C Corp an ideal entity structure for venture capitalists or investors

On the down side, the entity is subject to double taxation. A C Corp pays a 21% flat tax rate at the entity or corporate level, and shareholders are also subject to taxes on any money taken from the business (usually as dividends).

When are C Corporation tax returns due?

A C Corporation with a fiscal year of January to December must file its tax return by April 15. However, if your fiscal year ends in another month, your return is due on the 15th day of the fourth month after year end.

A C Corp is generally required to make quarterly estimated payments, for income received throughout the year. 

For estimated tax purposes, the year is divided into four payments periods:

  • April 15th – Covers income earned from January 1 to March 31
  • June 17th – Covers income earned from April 1 to May 31
  • September 16th – Covers income earned from June 1 to August 31
  • January 15th – Covers income earned from September 1 to December 31

How to pay your estimated taxes

Form 1040-ES can be submitted along with your estimated payment by mail, online, or via the IRS2Go app. You can pay your estimated taxes once-off or in installments, as long as the total amount is paid by the deadline at the end of the quarter.

C Corporation tax filings

A C corporation files its tax return on Form 1120. Shareholders will also complete different forms, depending on how they receive their income from the corporation. If this is from wages or salaries, Form W-2 is used. Dividends are reported on Form 1099-DIV.

Tips for Filing Form 1120

  • Keep up-to-date accounting records and financial statements. Accurate balance sheets and income statements ensure that you don’t report too much (or too little) income. 
  • Record your income. Your business’ income is recorded in the first section of Form 1120.
  • Record your expenses. Expenses are recorded in the second section of the form.
  • Calculate your net profit or loss. On a C Corporation tax return, the technical name for your business’s profit or loss is “ordinary income or loss”. To calculate ordinary income, subtract your total expenses from your gross income. 
  • Record taxes owed and payments made. Calculate your C Corporation’s tax liability according to the Form 1120 instructions. Also record any payments made or tax credits used during the year.
  • Determine balance owed or overpayment. The final dollar amount on Page 1 of Form 1120 indicates whether you’ve over- or underpaid the US treasury.

Schedules of Form 1120

  • Schedule C. This schedule calculates any dividends that will be distributed to shareholders, along with various special deductions.
  • Schedule J. This schedule computes your C Corp tax liability.
  • Schedule K. This schedule allocates the dollar amounts of each shareholder’s percentage of ownership, income, deductions, and tax payments. 
  • Schedule L. This is used to report your business’s balance sheet.
  • Schedule M-1. Here, you can reconcile taxable and non-taxable income, along with deductible and non-deductible expenses.
  • Schedule M-2. This schedule is a more detailed look at retained earnings.
