A tax deduction reduces the amount of income that is subject to taxation. It allows individuals and businesses to lower their taxable income by subtracting eligible expenses from total earnings. Common deductions include mortgage interest, charitable donations, medical expenses, and business-related costs.
For businesses, deductions might cover expenses such as office rent, equipment, travel, and professional fees. Accurate record-keeping is critical because every deduction must be supported by receipts or documentation in case of an audit.
By claiming deductions, taxpayers effectively reduce their overall tax bill. For example, if a business earns $100,000 and claims $20,000 in deductions, it only pays tax on $80,000. Understanding which deductions apply to your situation can lead to significant savings. Consulting a tax professional helps ensure compliance and maximizes the benefit of available deductions while staying within IRS guidelines.
