Vanlige feil å unngå

  • Deducting 100% of internet costs when personal use (streaming, social media) accounts for significant portion
  • Double-counting internet in both the home office deduction (regular method) and as a separate business expense
  • Not being able to substantiate the business-use percentage if audited — keep a usage log for the first month to establish your ratio

Ofte stilte spørsmål

Can W-2 remote workers deduct home internet?

No. Since the 2017 Tax Cuts and Jobs Act, W-2 employees cannot deduct unreimbursed business expenses on federal taxes. This deduction is only available to self-employed individuals and business owners.

What business use percentage is reasonable?

The IRS does not set a specific percentage. For full-time self-employed workers, 50-75% is generally considered reasonable. Document your estimate by tracking usage for one representative week.
