Form 1040 Schedule A: Itemized Deductions (2011) – A Complete Guide
What Form 1040 Schedule A Is For
Schedule A (Form 1040) is an attachment to your main tax return that allows you to claim itemized deductions instead of taking the standard deduction. Think of it as a detailed list of specific expenses the IRS lets you subtract from your income to reduce your tax bill. These expenses fall into seven categories: medical and dental costs, taxes you paid, interest payments, charitable donations, casualty and theft losses, job-related expenses, and certain other miscellaneous costs.
In 2011, you would compare your total itemized deductions to the standard deduction amounts ($5,800 for single filers, $11,600 for married filing jointly, $8,500 for heads of household, and $5,800 for married filing separately). You'd then choose whichever amount is higher to claim on your Form 1040. Most taxpayers find itemizing worthwhile when they have significant deductible expenses like mortgage interest, substantial medical bills, or large charitable contributions that together exceed their standard deduction.
When You’d Use Form 1040 Schedule A
Original, Late, and Amended Filing
You file Schedule A along with your Form 1040 by the regular tax deadline, which was April 15, 2012, for the 2011 tax year (or October 15, 2012, if you filed for an extension). If you initially took the standard deduction but later realized that itemizing would save you more money, you can file an amended return using Form 1040X within three years from the date you filed your original return or within two years from the date you paid the tax, whichever is later.
Common reasons for filing an amended return to add or change Schedule A include discovering forgotten deductions like charitable contributions, receiving corrected mortgage interest statements (Form 1098), finding additional medical expense receipts, or realizing that state tax refunds received should have reduced your prior-year deduction. When amending, you must attach a new or corrected Schedule A to Form 1040X, showing what you originally reported and what the correct amounts should be.
Key Rules or Details for 2011
Medical and Dental Expenses
Medical and Dental Expenses: You can only deduct the portion exceeding 7.5% of your adjusted gross income (AGI). For example, if your AGI is $50,000, you must have more than $3,750 in unreimbursed medical expenses before anything becomes deductible. Qualifying expenses include doctor visits, hospital care, prescription medications, insurance premiums (unless paid with pre-tax dollars), medical equipment, and mileage to medical appointments (19 cents per mile for January through June 2011, 23.5 cents per mile for July through December 2011).
Taxes You Paid
Taxes You Paid: You may deduct either state and local income taxes OR state and local general sales taxes—not both. You can also deduct real estate taxes (but not charges for services like trash collection) and personal property taxes based on value (like the value-based portion of your car registration). The key requirement is that these taxes must be based on assessed value and imposed for general governmental purposes.
Interest You Paid
Interest You Paid: Home mortgage interest is deductible if the mortgage is secured by your main home or second home. For mortgages taken out after October 13, 1987, debt limits apply: up to $1 million for acquisition debt ($500,000 if married filing separately) and up to $100,000 for home equity debt ($50,000 if married filing separately). Points paid on home purchases are generally deductible in the year paid, but points on refinancing must typically be deducted over the life of the loan. Mortgage insurance premiums paid in 2011 may be deductible unless your AGI exceeds $109,000 ($54,500 if married filing separately), with phase-outs beginning at $100,000 ($50,000 if married filing separately).
Charitable Contributions
Charitable Contributions: Donations to qualified organizations are deductible, but strict recordkeeping rules apply. For cash donations of any amount, you need bank records or written acknowledgment from the charity. For donations over $250, you must have a contemporaneous written receipt from the organization. For property donations over $500, you must complete Form 8283. Vehicle donations over $500 require Form 1098-C or equivalent written acknowledgment attached to your return.
Miscellaneous Deductions and Losses
Miscellaneous Deductions: Unreimbursed employee expenses, tax preparation fees, and certain investment expenses are deductible only to the extent they exceed 2% of your AGI. Casualty and theft losses from federally declared disasters are deductible only after subtracting $100 per event and only for the amount exceeding 10% of your AGI.
Step-by-Step (High Level)
Step 1: Gather Your Records
Step 1: Gather Your Records – Collect all receipts, statements, and documentation for the year. This includes medical bills and EOBs (explanation of benefits), property tax bills, Form 1098 for mortgage interest, charitable donation receipts, state tax returns showing payments made, and records of miscellaneous expenses.
Step 2: Calculate Each Category
Step 2: Calculate Each Category – Work through each section of Schedule A. For medical expenses, subtract any insurance reimbursements and then apply the 7.5% AGI threshold. For taxes, decide whether to claim income taxes or sales taxes (use the optional sales tax tables if you didn't keep receipts). Add up all qualifying tax payments. For interest, use the amounts from Form 1098 plus any additional qualifying interest not reported there. Total all charitable contributions with proper documentation.
Step 3: Apply Thresholds and Limits
Step 3: Apply Thresholds and Limits – Remember that medical expenses and miscellaneous deductions have AGI percentage floors (7.5% and 2% respectively). Check if any special limits apply to you, such as the mortgage insurance premium phase-out if your AGI exceeds $100,000. For casualty losses, subtract $100 per event, then apply the 10% AGI threshold to your total losses.
Step 4: Complete the Form
Step 4: Complete the Form – Enter each category's total on the appropriate lines of Schedule A. The form walks you through: Lines 1-4 for medical and dental; Lines 5-8 for taxes; Lines 10-14 for interest; Lines 15-19 for charitable gifts; Line 20 for casualty losses; Lines 21-27 for job expenses and miscellaneous; and Line 28 for other miscellaneous deductions with no AGI limit.
Step 5: Total and Transfer
Step 5: Total and Transfer – Add up all your itemized deductions on Line 29. Compare this total to your standard deduction amount. If your itemized deductions are higher, enter the Schedule A total on Form 1040, Line 40. If the standard deduction is higher, claim that instead and don't attach Schedule A to your return.
Common Mistakes and How to Avoid Them
Double-Dipping Deductions
Double-Dipping Deductions: Never claim the same expense in two places. For example, don't include health insurance premiums on both Schedule A and as a self-employed health insurance deduction on Form 1040, Line 29. Always reduce Schedule A medical expenses by amounts deducted elsewhere.
Forgetting to Reduce for Reimbursements
Forgetting to Reduce for Reimbursements: If your insurance company reimbursed you for medical expenses or if you received a property tax refund during 2011, you must subtract these amounts from your deductions. Many taxpayers forget to reduce their deductible expenses by reimbursements received in the same year, which can trigger IRS notices.
Including Non-Deductible Expenses
Including Non-Deductible Expenses: Not all expenses that seem related to deductible categories actually qualify. You cannot deduct the cost of diet food, cosmetic surgery (unless medically necessary), over-the-counter medications, funeral costs, federal taxes, homeowners association fees, or charges for specific services (like trash collection) as property taxes. Read the instructions carefully to distinguish deductible from non-deductible items.
Missing AGI Thresholds
Missing AGI Thresholds: Many taxpayers calculate their medical or miscellaneous expenses correctly but forget to subtract the AGI percentage floor. Remember: if your AGI is $60,000, medical expenses are only deductible above $4,500 (7.5% of $60,000), and miscellaneous expenses only above $1,200 (2% of $60,000).
Poor Recordkeeping
Poor Recordkeeping: The IRS requires specific documentation for many deductions, especially charitable contributions. Keep bank records for all cash donations, written acknowledgments for gifts over $250, and Form 8283 for property donations over $500. Maintain these records for at least three years after filing. If audited, you must provide substantiation or lose the deduction.
Not Comparing to Standard Deduction
Not Comparing to Standard Deduction: Some taxpayers automatically itemize without checking if it actually benefits them. Always calculate your total itemized deductions and compare to your standard deduction before deciding which to claim. If your itemized deductions are only slightly higher, the standard deduction might be simpler and equally beneficial.
What Happens After You File
Once you mail your return with Schedule A attached (or e-file it), the IRS processes your return and compares your reported deductions to statistical norms and information they receive from third parties. Your Form 1098 mortgage interest statements, Form 1099-INT for investment interest, and charitable organization reports help the IRS verify your claims.
If your deductions appear reasonable and match third-party records, your return is typically processed without issue, and you receive any refund due within 21 days for e-filed returns or six to eight weeks for paper returns. You should maintain all receipts, statements, and supporting documents for at least three years from the filing date or due date, whichever is later, as the IRS generally has three years to audit returns (longer in cases of substantial underreporting).
Certain red flags may trigger additional scrutiny, including unusually high charitable deductions relative to income, large casualty losses, significant miscellaneous expenses, or inconsistencies between your Schedule A and information returns on file with the IRS. If the IRS has questions, you may receive a letter requesting additional documentation or explanation. In some cases, your return may be selected for audit, though most Schedule A filers are not audited.
If you discover an error after filing, you can file Form 1040X to amend your return. If the error results in additional tax owed, file the amendment as soon as possible to minimize interest charges. If you're owed an additional refund, you have three years from the original filing date to claim it. The IRS typically takes 8 to 12 weeks to process amended returns.
FAQs
Should I itemize or take the standard deduction?
Itemize if your total qualifying expenses exceed your standard deduction amount. For 2011, itemizing typically makes sense if you have significant mortgage interest, high medical expenses, substantial charitable contributions, or a combination of deductible expenses. Use Schedule A as a worksheet first to calculate your total itemized deductions, then compare to your standard deduction before deciding.
Can I deduct medical expenses I paid for my parents or other family members?
Yes, but only if they meet the definition of your dependent or would be your dependent except that they earned $3,700 or more in gross income. For example, if you provided over half your mother's support but she earned $3,700 in 2011, she's not technically your dependent, but you can still deduct medical expenses you paid for her. The key is the support test, not the income test, when it comes to medical expense deductions.
What if my spouse and I file separately—how do we split itemized deductions?
If one spouse itemizes deductions, the other spouse must also itemize (neither can take the standard deduction). You each deduct expenses you paid from your own separate funds. For jointly paid expenses (such as from a joint checking account), you generally split the deduction equally unless only one spouse qualifies for a particular deduction. Maintain detailed records showing who paid what.
Can I deduct points I paid when refinancing my mortgage?
Points paid on a refinance must generally be deducted over the life of the loan rather than all at once in the year paid. If you refinanced a 30-year mortgage and paid $3,000 in points, you would deduct $100 per year ($3,000 ÷ 30 years) for the life of the loan. However, if part of the refinancing proceeds improved your main home, you may deduct the portion of points related to the improvement in the year paid.
What happens if I receive a state tax refund in 2012 for taxes I deducted on my 2011 Schedule A?
If you itemized in 2011 and the deduction reduced your tax, you must report the state tax refund as income on your 2012 Form 1040, Line 10. This is known as the "tax benefit rule." If you took the standard deduction in 2011, or if itemizing didn't reduce your tax, the refund is not taxable. The IRS typically sends you Form 1099-G showing the refund amount.
Do I need to attach receipts and documentation to my return?
No, do not attach receipts, bank records, or charitable acknowledgment letters to your tax return. Keep these documents with your tax records for at least three years in case the IRS asks for verification. However, you must attach Form 8283 for non-cash charitable contributions over $500 and Form 1098-C or equivalent written acknowledgment for vehicle donations over $500.
Can I deduct interest on a home equity loan used to pay off credit cards?
For tax year 2011, yes—home equity loan interest was deductible up to the $100,000 limit ($50,000 if married filing separately) regardless of how you used the proceeds, as long as the loan was secured by your main home or second home. Note that this rule changed for tax years 2018-2025, but for 2011 returns, the interest is deductible regardless of how you spent the borrowed money.
