Salaried Exempt Vs. Salaried Nonexempt. Although several criteria separate salaried exempt workers from salaried nonexempt workers, the one key difference between salaried exempt status and salaried nonexempt status is overtime pay. Exempt employees don't receive overtime pay; nonexempt employees do. The classification criteria for exempt and nonexempt workers are part of the Fair Labor Standards Act, or the FLSA, which is the federal law that governs minimum wage, overtime pay and working hours.
Investment Interest and Tax Deductions. One exception to the general rule that interest is tax deductible is investment interest. Investment interest payments are paid on indebtedness properly allocable to property held for investment, such as stocks held on margin, loans to others, etc.
You can also generally deduct interest on home equity debt of up to $100,000 ($50,000 if you're married and file separately) regardless of how you use the loan proceeds. For details, see IRS Publication 936: Home Mortgage Interest Deduction.
