Understanding Itemized Deductions
Itemizing your deductions means you are listing out specific eligible expenses on your tax return to reduce your taxable income. This is an alternative to taking the standard deduction, which is a fixed dollar amount that varies by filing status. You should itemize if your total eligible itemized deductions are greater than the standard deduction for your filing status.
Key Categories of Itemized Deductions:
Medical and Dental Expenses: You can deduct qualified medical and dental expenses that exceed 7.5% of your Adjusted Gross Income (AGI). This includes payments for doctors, dentists, hospitals, prescription medications, and medical aids.
State and Local Taxes (SALT): This category includes state and local income taxes, or sales taxes, plus property taxes (on real estate and sometimes personal property). However, the total deduction for SALT is capped at $10,000 per household per year.
Home Mortgage Interest: You can typically deduct interest paid on mortgage debt for a primary home and a second home, up to certain limits.
Investment Interest: Interest paid on money borrowed to purchase taxable investments can be deducted, but only up to the amount of your net investment income.
Charitable Contributions: Donations made to qualified charitable organizations are deductible. This can include cash contributions, as well as non-cash donations like clothing, vehicles, or stocks, subject to specific rules and limitations.
Other Deductions: This category is more limited but can include things like casualty and theft losses from federally declared disaster areas, and certain unreimbursed employee expenses (though these are very restricted for most taxpayers after tax law changes).
How the Calculator Works:
This calculator sums up the eligible amounts you enter for each deduction category. For Medical Expenses, remember that only the amount exceeding 7.5% of your Adjusted Gross Income (AGI) is deductible. The calculator assumes you have already calculated this excess amount and entered it. The SALT deduction is subject to the $10,000 annual limit. The calculator provides a simple sum of your provided eligible expenses to give you a preliminary estimate of your potential total itemized deductions.
When to Itemize vs. Take the Standard Deduction:
The decision to itemize depends on comparing your total potential itemized deductions to the standard deduction amount for your filing status:
Single: $13,850 (for 2023)
Married Filing Separately: $13,850 (for 2023)
Married Filing Jointly: $27,700 (for 2023)
Head of Household: $20,800 (for 2023)
*(Standard deduction amounts are for the 2023 tax year and are subject to change annually.)*
If your calculated itemized deductions exceed these standard amounts, itemizing is generally more beneficial. Always consult with a tax professional or refer to IRS publications for the most accurate and up-to-date information regarding tax laws and your specific situation.
