Couples Fight IRS Over Home and App Costs

USATuesday, February 10, 2026

A married couple operated multiple projects under a single LLC, including:

  • House Building on their large farm
  • App Development to help reduce internet usage
  • Mulching Side Job

After filing taxes for 2017-2019, the IRS disallowed many of their business expense claims. The couple appealed to the Tax Court for review.

Court's Decision

The court examined each activity separately:

✅ Allowed Deductions

  • Home-Building: Mostly done for profit; expenses deductible if proven legitimate.
  • App Project: Aimed at generating revenue; expenses allowed.

❌ Disallowed Deductions

  • Mulching Venture: Lacked clear profit motive; most expenses rejected.

Final Ruling

The court upheld most deductions for the profitable parts of their business.

Key Takeaway: The IRS scrutinizes expenses, but small businesses can legitimately claim costs when they are genuinely profit-driven.
