What Are Quarterly Estimated Tax Payments?

You might have to pay estimated taxes, depending on how much you owe and on your business type. Most small business owners don’t receive paychecks, so income taxes and taxes for Social Security and Medicare aren’t withheld from their pay. The IRS requires taxes to be paid throughout the year, and estimated taxes are the way to make these payments when they’re not withheld. The amount of estimated tax must be calculated to include:

The amount of income you made from the business during a year, and The amount of self-employment tax (Social Security and Medicare) you owe based on that income.

Corporations and Pass-Through Entities

Corporations (the businesses, not the owners) must make estimated tax payments if the tax due is $500 or more for the year. Businesses that are not corporations are known as pass-through entities. The business’ taxes pass through to the owners on their personal income tax returns. Your business tax is calculated on Schedule C - Profit or Loss for Business if your business is a sole proprietorship or a single-member LLC, which is included with your personal Form 1040 tax return. Your share of the profits of the business is shown on a Schedule K-1 (Form 1065) if your business is a partnership, a multiple-member LLC, or an S corporation. This schedule is also included with your personal tax return when you file.
