Non-reimbursed Employment Expenses and Income Taxes
2018 law through 2025: Under the 2017 Tax Cuts and Jobs Act, however, the unreimbursed employee work expenses deduction is eliminated beginning in 2018.
Pre-2018 treatment: Non-reimbursed employment expenses refers to any kind of special tools or clothing you needed for employment that you paid for out-of-pocket. Deductible job-specific expenses include licensing fees, membership dues for professional organizations, subscription’s to professional magazines, job-related educational expenses, record’s relating to the use of your home as a home office, as well as travel-related expenses, meals and laundry. Travel expenses and commuting costs may be deductible only if your job is temporary and you do not work there for more than one year.
Theft and Casualty Losses and Income Taxes
2018–through 2025 treatment: The deduction for personal casualty and theft losses was suspended with the enactment of the 2017 Tax Cuts and Jobs Act, beginning 2018 through 2025. There is no itemized deduction for those years unless the personal casualty and theft losses were incurred in presidentially-designated disaster areas.
Theft and casualty losses refers to all property losses due to fire, floods, earthquakes, vandalism, accidents, federal disasters or theft. In addition to records for these types of losses, you may also need records of appraisal fees and photography expenses incurred for the purpose of proving you had a loss.
Charitable Donations and Income Taxes
If you donated money or property to a charitable organization, the donation may be deductible. In addition to receipts from donations to charitable organizations, you should also total receipts for travel expenses relating to volunteer work (if applicable), including mileage, tolls, and parking, when you file your income tax return.
