Washington State Deduction Laws are laws that allow individuals and businesses to reduce the amount of income they report to the Internal Revenue Service (IRS) for taxation purposes. Individuals may reduce their taxable income by claiming deductions such as the standard deduction, itemized deductions, and other deductions related to their filing status. Businesses may deduct certain expenses, including wages, rent, and utilities, to reduce their taxable income. There are several types of Washington State Deduction Laws, including: 1.
