Many deductions are often overlooked due to the hassle of recordkeeping or simply not knowing they exist. With a bit of organization and education, you can ensure you're maximizing your write-offs and reducing your tax bill. Commonly missed deductions include the home office deduction, vehicle expense deduction, business use of cell phone and internet bills, and the self-employed health insurance deduction. Most of these are primarily available to self-employed individuals, so if you're a W-2 worker, be sure and speak with your CPA about deductions that are available to you, and make sure to keep good records.
