Purpose of Schedule A
Schedule A is required in any year you choose to itemize your deductions. The schedule has seven categories of expenses: medical and dental expenses, taxes, interest, gifts to charity, casualty and theft losses, job expenses and certain miscellaneous expenses. Beginning in 2018, miscellaneous expenses are no longer deductible. Each of these categories has different requirements and limitations on the amount you can deduct.
Preparing the Schedule A
When you prepare the Schedule A, you do not have to complete every line or include expenses in each category; just those that you are eligible to claim. Although many taxpayers have deductions for each category, having just one deductible expense may be sufficient to justify itemizing. For example, the mortgage interest deduction alone can be quite significant and by itself, be greater than the Standard Deduction. When you are done filling out the schedule and applying the specific limitations, you then transfer your total deduction to Form 1040.
When you use TurboTax, we’ll ask simple questions about your deductions and fill out the Schedule A for you.
Comparison to the Standard Deduction
Using Schedule A to itemize your deductions allows you to claim a number of personal expenses; however, it may not make financial sense to do so since you give up the Standard Deduction. In 2024 for example, the Standard Deduction for a taxpayer filing as Single is $14,600. If you have $1,000 in charitable donations and pay $2,000 of mortgage interest during the year, your itemized deductions are only $3,000. In this case, you can save more in income taxes by claiming the Standard Deduction instead of itemizing.
Schedule A tips
Keeping accurate and detailed financial records of your expenses during the year can reduce the amount of time you spend preparing the Schedule A and may also be helpful when evaluating the deductibility of each expense. Some itemized deductions, such as property and sales taxes, are often overlooked. For example, not only can you deduct property taxes on your home, but also on the boats and mobile homes you own. Beginning in 2018, the deduction for state and local taxes is limited to $10,000 per year.
In addition, you can deduct either state income tax or state sales tax that you pay, but not both. For purposes of calculating your sales tax deduction, retaining receipts for all purchases you make during the year is imperative to maximizing your tax savings although or you can claim the amount from the IRS sales tax tables instead.
