Understanding Your Tax Obligations

Online business owners, like all entrepreneurs, are subject to various taxes, which can vary depending on the business structure and location. The key taxes you may need to pay include:

  • Income Tax: The income generated from your online business is subject to federal and state income taxes. Ensure that you report your earnings accurately and pay the necessary taxes.
  • Self-Employment Tax: If you're a sole proprietor or run a single-member LLC, you'll be responsible for both the employer and employee portions of Social Security and Medicare taxes.
  • Sales Tax: Depending on your business's location and the nature of your products or services, you may be required to collect and remit sales tax.
  • Employment Taxes: If you have employees, you'll need to withhold and remit federal income tax, Social Security, and Medicare taxes.

Deductions for Running an Online Business

One way to minimize your tax liability is by taking advantage of deductions available for online business owners. Some common deductions include:

  • Home Office Deduction: If you use part of your home exclusively for your business, you can deduct a portion of your rent or mortgage, utilities, and maintenance expenses.
  • Business Expenses: You can deduct expenses directly related to your business, such as website maintenance, marketing, office supplies, and business travel.
  • Startup Costs: You can amortize startup costs over time, including legal and accounting fees, market research, and advertising expenses.
  • Retirement Contributions: Online business owners can contribute to retirement plans like a Simplified Employee Pension (SEP) or a Solo 401(k) and reduce their taxable income.
  • Health Insurance Premiums: Deducting health insurance premiums can be especially valuable for self-employed business owners.

Using a Tax Attorney for Maximizing Deductions

While these deductions can significantly lower your tax liability, there's one tax-saving strategy that is often overlooked: Section 119 of the Internal Revenue Code.

Section 119 - Deductibility Under Section 119

Section 119(a)(2) of the Internal Revenue Code states, "There shall be excluded from gross income of an employee the value of any meals or lodging furnished to him, his spouse, or any of his dependents by or on behalf of his employer for the convenience of the employer, but only if... in the case of lodging, the employee is required to accept such lodging on the business premises of his employer as a condition of his employment."

This means that if an employee is contractually required to accept lodging on the business premises as a condition of employment, and this condition benefits the employer, it is both deductible for the employer and excludable from income for the employee.

Condition of Employment

To meet the "condition of employment" requirement, you need a legally enforceable contractual provision that makes lodging acceptance a condition of employment. Notably, the requirement is separate from the "convenience of the employer" standard.

On the Business Premises

Code section 119(b)(1) defines "business premises of the employer" as the place of employment of the employee. The IRS and legal authorities have clarified that the premises must either be an integral part of the business property or a place where the employer conducts business activities. The home of a self-employed individual can qualify as the business premises if they conduct business-related activities there.

For Benefit of the Employer

The "convenience-of-the-employer" and "condition-of-employment" tests are essentially the same. There must be a "direct nexus" between the lodging furnished and the employer's business interests. Even if your employment agreement lacks an explicit requirement for lodging acceptance, it can still qualify if it is practically necessary for the employee's duties.

Section 280A does not apply thanks to the carve-out for Section 119 applicability under Section 280A(d)(2)(c).


Online business owners can significantly benefit from optimizing their tax strategies, and Section 119 of the Internal Revenue Code provides a valuable avenue for deductions. By operating your business from your personal residence, you can effectively provide lodging on what would be considered the business premises, making it deductible.
