To answer this question, we have to first identify what qualifies as a business. Along with the IRS guidelines we mentioned earlier, there is also the "safe harbor" rule. If you have managed to earn a profit three out of five years, the IRS will assume that you are operating as a business.
Business losses are natural in the first few years, and the IRS allows you to use your losses as a tax deduction. But this is only available to non-corporations (LLC, partnerships, sole proprietors).
And there is a
loss limit: $305,000 if you’re filing as an individual and $610,000 if you’re filing jointly. A business loss limit is the maximum amount of loss you are allowed to deduct from your net loss in a year. You can also carry forward your loss to the next tax year, meaning you can count it as an expense and deduct it. But you can only do this for up to 80% of your taxable income.
So, if you had a loss of $400,000 in 2024, and your taxable income was $350,000. You are allowed to deduct $305,000 of your loss due to the limit, so your new taxable income becomes $45,000 ($350,000 - $305,000). The remaining loss of $95,000 can be carried forward to the next year.
The IRS allows for carried forward business losses to be written off only up to 80% of taxable income. In this case, if you made $350,000 in 2024, you can write off the entire amount as an expense as it does not exceed 80% of your income (80/100 x 350,000 = 280,000). This makes your new taxable income for the next year $245,000 ($350,000 - $95,000).
