Schedule A (Form 1040) (2016) allows taxpayers to report itemized deductions instead of taking the standard deduction on their federal income tax return. You can lower your taxable income by listing qualified expenses and reducing your overall tax liability. For the 2016 tax year, everyday deductible expenses included medical and dental costs, state and local taxes, home mortgage interest, charitable donations, and other qualified expenses.
Itemizing was most beneficial for taxpayers whose total deductions exceeded the standard deduction, such as homeowners or those with significant medical or charitable expenses.

When You’d Use Schedule A (Form 1040)
Schedule A (Form 1040) is used when itemized deductions offer a greater tax benefit than claiming the standard deduction on a federal income tax return. For the 2016 tax year, this form enabled taxpayers to reduce their taxable income by reporting specific deductible expenses, including mortgage interest, charitable contributions, or substantial medical bills.
You would typically file Schedule A in the following situations:
- Total deductions exceed the standard deduction. This typically benefits homeowners, individuals with high medical expenses, or taxpayers who have made significant donations.
- Eligible expenses were paid during 2016: These deductible costs may include mortgage interest, property taxes, and state or local income taxes, as long as they meet the IRS requirements for itemized deductions.
- A late or amended return is being filed: If changes are needed after submitting your original return, file Form 1040-X with an updated Schedule A. This allows you to correct errors or include any missed deductions on your initial filing.
- The IRS refund window is still open: For 2016 returns, refund claims were accepted until April 18, 2020.

By following these clear, sequential steps, you can simplify the process of completing IRS Schedule A (Form 1040) for 2016. Each one ensures that deductions are calculated correctly and that the final tax payment or refund amount is accurate.
- Gather all supporting records: Collect receipts for unreimbursed expenses, Forms 1098 and W-2, and documentation for estimated tax payments or potential tax credits.

- Report taxes paid: Choose whichever is higher—state and local income taxes or general sales taxes—and record the payment amount accurately.
- List significant deductions: Include mortgage interest, charitable donations, and qualified business expenses, applying adjustments where necessary.
- Review credits: Identify any applicable tax credits that may reduce your overall tax bill.

Common Mistakes and How to Avoid Them
Overlooking key details can result in costly errors when filing IRS Schedule A (Form 1040) 2016. Below are common mistakes and practical ways to avoid them:
- Claiming reimbursed or undocumented expenses: Only deduct amounts actually paid out-of-pocket. Review your bank account records and keep receipts to support every claim.
- Missing the filing deadline: Submitting your return late can trigger late payment penalties and interest. Remember to note important dates in advance, ensure timely filing, and consider using e-filing if feasible. Review our unfiled returns page to understand how to correct missing filings, including prior-year itemized deduction returns such as 2016.
- Ignoring deduction limits: Always verify income-based thresholds before claiming expenses, especially for medical costs and charitable donations. Follow IRS instructions to stay compliant.
- Mixing personal and business deductions: If self-employed, track business expenses separately to prevent mistakes and maintain clear records.
- Incorrectly splitting deductions: Married couples and a surviving spouse should coordinate with their spouse to ensure that only one person claims shared expenses, thereby avoiding duplicate deductions and audit risks.
What Happens After You File
After submitting IRS Schedule A (Form 1040) (2016) with your federal income tax return, the IRS reviews your filing for accuracy. Most returns are processed within six to eight weeks, and refunds are typically sent by direct deposit to your bank account. If you owe taxes, payment should be made by the original due date to avoid interest or penalties. In some cases, the IRS may review deductions that appear unusually high. Keep all receipts and records for at least three years, as additional documentation may be requested during an audit.
