Income Tax Regulations: Understanding Your Income Tax Obligations

As an e-commerce seller, understanding your income tax obligations is essential for complying with the law and avoiding potential penalties. Income tax is charged on the generated net income of your e-commerce business.

To determine your income tax liability, you need to classify your business for tax purposes. The most common classifications for e-commerce businesses are:

  • Sole Proprietorship
  • Partnership
  • Limited Liability Company (LLC)
  • Corporation

Understanding the classification of your e-commerce business will help determine your reporting and filing requirements. We will further discuss this in the later part of the blog.

Income Tax Regulations: Determining Your Net Income

Calculating your net income is vital in determining your income tax liability. Net income is the amount left after deducting allowable expenses from your total revenue. The following components contribute to the calculation of net income for e-commerce sellers:

Income Tax Regulations: Revenue

Your e-commerce revenue includes the total sales generated from your online business. It encompasses the sales of products or services and other income sources related to your e-commerce operations.

Income Tax Regulations: Cost of Goods Sold (COGS)

COGS represents the direct costs associated with producing or acquiring the products you sell. It includes the cost of purchasing inventory, manufacturing costs, and shipping fees directly attributable to the products sold.

Income Tax Regulations: Operating Expenses

Operating expenses are the costs incurred to operate your e-commerce business. This includes expenses such as website hosting, marketing and advertising costs, office supplies, professional fees, shipping supplies, and software subscriptions.

Income Tax Regulations: Deductions

E-commerce sellers are eligible for various deductions that can reduce their taxable income. 

Common deductions include shipping costs, packaging expenses, advertising and marketing expenses, website development and maintenance costs, payment processing fees, and fees paid to online marketplaces.

By calculating your net income accurately, you can determine the taxable income on which your income tax liability will be based.

Income Tax Regulations: Reporting and Filing Requirements

Compliance with reporting and filing requirements is crucial to meet your income tax obligations. Here are the key steps to ensure proper reporting and filing:


Maintaining detailed and organised records of your income, expenses, and deductions is essential for accurate reporting. Use accounting software or digital tools to track and categorise your financial transactions.

Employer Identification Number (EIN)

If you have employees or operate your e-commerce business as a partnership or corporation, you need to get an Employer Identification Number (EIN) from the Internal Revenue Service (IRS).

Tax Forms

The specific tax forms you need to file depend on the classification of your e-commerce business.

Sole Proprietorship

As a taxable individual, a sole proprietor needs to report their business income and expenses on their personal income tax returns using Schedule C or Schedule C-EZ. Their business’s net income or loss is then transferred to your Form 1040.


Partnerships are required to file an informational tax return using Form 1065. This form reports the partnership’s income, deductions, and distributions. Each partner receives a Schedule K-1, which shows their share of the partnership’s income or loss.

Partners report this information on their individual income tax returns.


Corporations file their income tax returns using Form 1120. Additionally, if the corporation pays dividends to its shareholders, it must issue Form 1099-DIV to report those payments

Estimated Tax Payments

As an e-commerce seller, you may need to make estimated tax payments throughout the year to avoid getting charged penalties due to underpayment. Use Form 1040-ES to calculate and submit estimated tax payments to the IRS.

Filing Deadlines

The filing deadlines for income tax returns vary depending on the type of business entity and your tax year. Generally, individual income tax returns are due on April 15th, while partnership and corporation returns have different deadlines.

Be aware of any state-specific filing deadlines as well. Also, ensure you accurately report your income, deductions, and other required information to meet your income tax obligations.

For more confidence in income tax regulations compliance for your e-commerce business, it is recommended to consult a tax professional to help you.

Frequently Asked Questions

How much income is taxable in the USA?

Taxable income is subject to different tax rates based on the tax brackets. As of the tax year 2023, ordinary income in the United States is subject to seven different tax brackets: 10%, 12%, 22%, 24%, 35%, and 37%.

The applicable tax rate depends on the income level, with higher rates applying to higher income brackets.

Is there a VAT in the USA?

No, the United States does not have a nationwide Value-Added Tax (VAT) system. Instead, the U.S. relies on sales taxes imposed at the state and local levels.

Each state determines its sales tax rate, which is typically applied to the purchase price of goods and services at the point of sale.

Is tax evasion illegal in the US? 

Tax evasion is a prohibited act in the United States and is considered illegal. Engaging in deliberate actions to evade or underreport income, manipulate deductions, conceal assets, or commit other fraudulent activities to avoid paying taxes is a criminal offence.

Those found guilty of tax evasion may face severe penalties, including fines, penalties, and potential imprisonment.


As a US e-commerce seller, you must understand and adhere to income tax regulations. Proper reporting of income and expenses based on the chosen business structure, whether a sole proprietorship, partnership, LLC, or corporation, ensures compliance with the tax laws.
