For individual taxpayers, the tax year is the same as the calendar year, which means that it starts on January 1 and culminates on December 31. Business entities can follow the fiscal year or the calendar year. The question “when is tax season?” typically refers to the period in which tax returns can be sent to the IRS.

Tax filing season for the previous year starts on January 1 and ends with the regular filing deadline of April 15. If happened to be running behind and you had to file an extension then your tax filing is due by October 15.

Businesses

Business tax returns are due on March 15 for partnerships, and S-corporations. In the case of C-corporations, the deadline is on April 15 if they operate under the calendar year.

Limited liability and sole proprietors

Single member limited liability companies taxes are typically filed with the business owner’s personal tax return so the filing deadline is April 15th, and if an extension had to be filed then the tax filing is due by October 15th.

It would take several pages to explain the basics of how tax is calculated in the United States because of the great diversity of taxpayers and their different financial situations. What you should know is that American taxation is progressive, which means that tax assessment levels will increase along with the income you report. Marginal and effective tax rates at the federal level have a lot to do with how tax is calculated; they range between 10% and 37% as of 2021, and they are by no means among the highest in the world.

If we were to boil down tax calculations to a single paragraph it would be as follows:

The most applicable filing status must be ascertained first; this is followed by a determination of all income sources and qualified deductions. These steps result in the calculation of taxable income, but there will be additional workflows to figure out if the overall tax liability can be lowered by means of credits such as education, healthcare, and child care in the case of individual tax returns.

Businesses

Tax rates are currently 21% on taxable income for US C Corporations, whereas S Corporations and Partnerships remain “flow through” entities and are not subject to Federal tax. 

The process is different for business entities because of matters related to equipment, depreciation, payroll, and quite a few others; nonetheless, the common denominator crucial to tax calculation will always be the determination of taxable income. You can read our article explaining US corporate tax rates.

There are several entity structures that businesses can choose from. Each structure comes with its advantages and drawbacks. The entity type that would work best for your business depends on different factors such as the size of your organization, your preferred tax structure, and more. A small business accountant can help you choose the structure that will suit your needs best. This article will explore the most suitable entity structure for your business.
