One of the most underused tax deductions is the Section 179 deduction, which lets business owners write off the full cost of qualifying equipment or software in the year they buy it. For example, if you spend $50K on a piece of equipment, you can deduct the whole amount now instead of spreading it over years. This can save big on taxes and free up cash for other investments. I help clients by timing purchases in high-income years, making sure expenses qualify, and combining it with other deductions for maximum savings. If you're not using this, you're leaving money on the table!
