Short answer

Depends. Internet service may be tax deductible when it’s used for business or income-producing purposes and you can support the business-use portion.

If the internet plan is used for both business and personal reasons, you generally deduct only the business-use percentage.

Who this typically applies to

Employees often have stricter limits on deducting unreimbursed internet expenses. Reimbursement policies matter.

When internet is tax deductible

When internet is not tax deductible

Can I write off internet for my home business?

Yes. If you run a home business, you can typically write off the business portion of your home internet as a business expense.

How home business owners deduct internet

  • Self-employed (Schedule C filers): Deduct internet as a utility expense on Schedule C, Line 25 (Utilities) or as part of home office expenses
  • Business-use percentage: Calculate based on actual use (hours spent on business vs personal, or device allocation)
  • Home office deduction: If you claim a home office using the simplified method, internet may already be partially covered; if using actual expenses, include internet in your utility calculations

Common scenario: You work from home full-time running an online business and use internet 8 hours/day for work, 4 hours/day personal = 67% business use. On an $80/month bill, you'd deduct approximately $53/month ($636/year).

How to calculate the internet tax deduction

There are several reasonable ways to determine your business-use percentage for internet expenses.

Common allocation methods

  • Time-based: Track hours used for business vs personal over a representative period (e.g., business hours / total waking hours)
  • Device-based: If certain devices are business-only, estimate the bandwidth or usage those devices represent
  • Home office percentage: If you have a dedicated home office, some people use the same percentage as their home office square footage (though this is conservative)

Choose one reasonable method, document it, and apply it consistently. The IRS expects a logical approach, not perfection.

Example calculations

Example 1: Time-based allocation

  • Freelance consultant works from home 40 hours/week on business
  • Personal internet use (streaming, browsing): ~20 hours/week
  • Business percentage: 40 ÷ 60 = 67%
  • Monthly bill: $80 → Deductible amount: $53/month ($636/year)

Example 2: Conservative approach

  • Home-based online store owner uses internet heavily for business but also for family Netflix/gaming
  • Chooses conservative 50% business allocation to be safe
  • Monthly bill: $90 → Deductible amount: $45/month ($540/year)

Being conservative is fine. The IRS doesn't require a perfect calculation, just a reasonable and supportable one.
