Schedule A (Form 1040) Filing Checklist for Tax Year 2010
Overview and 2010-Specific Tax Environment
Schedule A allows taxpayers to claim itemized deductions instead of the standard deduction. Tax year 2010 represents a uniquely favorable deduction environment because the Pease limitation on itemized deductions was eliminated, allowing taxpayers of any income level to claim their full itemized deductions without reduction.
The 2010 standard deduction amounts are $11,400 for married individuals filing jointly, $8,400 for heads of household, and $5,700 for single filers and married individuals filing separately. Taxpayers should complete Schedule A only if total itemized deductions exceed these amounts.
Key 2010 Provisions
The American Recovery and Reinvestment Act provisions remain in effect for 2010, including the new tax deduction for motor vehicles purchased after February 16, 2009, and before January 1, 2010. This temporary provision allows deduction of state and local sales or excise taxes paid on qualifying vehicle purchases, subject to income limitations.
The elimination of the Pease limitation means that high-income taxpayers can claim full itemized deductions without the income-based phase-out that applied in prior years and will continue to apply in subsequent years.
Ten-Step Itemized Deduction Checklist
Step 1: Determine Whether to Itemize
Calculate your total potential itemized deductions by reviewing all qualified expenses in each category. Compare this total to your standard deduction amount based on filing status. Itemize only if your total itemized deductions exceed the standard deduction, as this results in lower taxable income and reduced tax liability.
Gather documentation for all potential deductions, including medical expenses, state and local taxes, home mortgage interest, charitable contributions, casualty losses, and miscellaneous deductions subject to the two percent floor.
Step 2: Calculate Medical and Dental Expenses
Medical and dental expenses are deductible only to the extent they exceed 7.5 percent of adjusted gross income. Determine AGI from Form 1040 line 38, multiply by 0.075 to identify the threshold amount, and deduct only expenses exceeding this threshold.
Qualified medical expenses include diagnostic tests, prescription medications, insulin, hospital care (including meals and lodging), clinic costs, laboratory fees, surgery to correct defective vision (such as laser eye surgery and radial keratotomy), medically necessary travel, and medical equipment. Long-term care insurance premiums qualify, subject to age-based limitations.
Non-deductible expenses include personal hygiene products, cosmetic surgery, health club memberships, and funeral or burial costs. Reduce total expenses by any insurance reimbursements received or expected. Enter the deductible amount that exceeds the 7.5 percent threshold on Schedule A line 4.
Step 3: Make State and Local Tax Election
Choose to deduct either state and local income taxes OR state and local general sales taxes, but not both. Select box (a) on line 5 for income taxes or box (b) for general sales taxes.
If deducting income taxes, include amounts withheld from wages shown on Form W-2, estimated tax payments made during 2010, and state tax paid with a prior year return filed during 2010. If deducting sales taxes, use either actual receipts or the optional state sales tax tables provided in Schedule A instructions. The optional tables show estimated deductions based on income and the number of exemptions.
Add real estate taxes paid to state or local governments on property you own, provided taxes were assessed uniformly and used for general community purposes. Include personal property taxes based on property value, such as vehicle taxes, if assessed annually.
Step 4: Calculate New Motor Vehicle Tax Deduction
For vehicles purchased after February 16, 2009, and before January 1, 2010, deduct state and local sales or excise taxes paid on the purchase. Complete the worksheet provided in Schedule A instructions to calculate the deductible amount.
The deduction is subject to limitations on the purchase price of the vehicle and income phase-outs. You cannot claim this deduction if your AGI equals or exceeds $135,000, or $260,000 if married filing jointly. Enter the calculated deduction on line 7.
Step 5: Report Home Mortgage Interest
Deduct home mortgage interest paid on loans secured by your main home or second home. For mortgages taken after October 13, 1987, interest is deductible on up to $1,000,000 of acquisition debt used to buy, build, or improve a home, or $500,000 if married and filing separately. Interest on up to $100,000 of home equity debt, or $50,000 if married filing separately, is also deductible.
Enter home mortgage interest reported on Form 1098 on line 10. Enter mortgage interest not reported on Form 1098, such as seller-financed arrangements, on line 11. Points paid on home purchases are deductible in the year they were paid. Points paid on refinancing must generally be deducted over the life of the loan.
Enter mortgage insurance premiums on line 13. For 2010, these premiums are deductible subject to income phase-out limitations.
Step 6: Calculate Investment Interest
Investment interest includes fees paid on loans to purchase investment property and margin interest on securities investments. This interest is deductible only up to the amount of net investment income. Complete Form 4952 to calculate the allowable deduction and attach it to your return. Enter the deductible amount on the appropriate Schedule A line.
Step 7: Document Charitable Contributions
Cash contributions to qualified charitable organizations recognized as tax-exempt under IRC section 501(c)(3) are deductible. Contributions to individuals or non-qualified organizations are not deductible. Obtain and keep written acknowledgment from the charitable organization for any single contribution of $250 or more.
For noncash contributions exceeding $500 but not exceeding $5,000, complete Form 8283 Section A and attach it to your return. For noncash donations exceeding $5,000, obtain a qualified appraisal from a qualified appraiser and complete Form 8283 Section B.
Clothing and household items are deductible only if in good used condition or better, except items valued over $500, which must be accompanied by a qualified appraisal and properly completed Form 8283. Vehicle donations require Form 1098-C, with the deductions generally limited to the fair market value or the amount the charity receives when selling the vehicle.
Charitable contribution deductions cannot exceed specific percentages of AGI, generally 50 percent for cash contributions to most charities, with different limits for appreciated property and private foundation contributions.
Step 8: Calculate Casualty and Theft Losses
For 2010, personal casualty or theft losses are deductible only if attributable to a federally declared disaster. Each casualty or theft loss is reduced by $100 per casualty, then all losses are totaled and reduced by 10 percent of AGI.
Complete Form 4684 and attach it to Schedule A. Enter the total allowable casualty and theft loss on Schedule A line 20. Casualty losses occur from fire, storm, shipwreck, or other sudden events. Theft is the illegal taking and removal of property with the intent to deprive the owner of it.
Maintain proof of casualty or theft, including documentation showing property ownership, occurrence of casualty or theft, and reasonable expectation of insurance or other reimbursement recovery. For federally declared disasters, you may elect to treat the loss as occurring in the preceding tax year.
Step 9: Report Job Expenses and Miscellaneous Deductions
Job expenses and certain miscellaneous deductions are subject to a two percent AGI floor. Deduct only amounts exceeding two percent of AGI. Unreimbursed employee expenses include job travel, union dues, job education and training, uniforms not suitable for everyday wear, and qualifying home office expenses.
Tax preparation fees are subject to the two percent floor. Other expenses include investment expenses and safe deposit box rentals. Calculate the threshold by multiplying AGI by 0.02, then subtract this from the total costs in this category. Enter only the excess on the appropriate line.
Gambling losses are not subject to the two percent floor but are deductible only to the extent of gambling winnings. Maintain detailed records of dates, gambling types, locations, amounts won and lost, and supporting documentation, including Form W-2G, wagering tickets, or casino receipts. Gambling losses cannot be deducted without reporting gambling winnings as income.
Step 10: Calculate Total and Assemble Forms
Add all amounts in the far-right column for lines 4 through 28 to determine total itemized deductions on line 29. Transfer this total to Form 1040 line 40. Compare total itemized deductions to your standard deduction to confirm itemizing provides a greater benefit.
Attach Schedule A to Form 1040 when itemizing. Include all required supporting forms: Form 4684 for casualty or theft losses, Form 8283 for noncash charitable contributions exceeding $500, Form 4952 for investment interest, and the new motor vehicle tax worksheet if applicable.
Enter your name and Social Security number on Schedule A, matching Form 1040. Place Schedule A behind Form 1040 in your return package, following the assembly instructions. Sign and date Form 1040. Both spouses must sign joint returns.
Record-Keeping Requirements
Maintain detailed records supporting all Schedule A deductions for at least three years from the filing date or two years from the tax payment date, whichever is later. For home purchase documents and mortgage records, retain records indefinitely to establish a basis for future home sale calculations.
Keep doctor bills, hospital invoices, insurance explanations of benefits, and prescription receipts for medical expenses. Retain charitable contribution receipts, contemporaneous written acknowledgments for contributions of $250 or more, and qualified appraisals for noncash donations over $5,000.
For casualty losses, keep photographs of the damaged property before and after the incident, insurance claim documents, and receipts showing the original cost. Retain Forms 1098 for mortgage interest, property tax bills, and all third-party statements supporting itemized deductions.
Special Considerations
Nonresident Aliens
Nonresident aliens generally file Form 1040NR and use Schedule A (Form 1040-NR) instead of Schedule A (Form 1040). Nonresident aliens cannot claim certain itemized deductions available to U.S. residents. If a nonresident alien married to a U.S. citizen or resident alien elects to file jointly, use the regular Schedule A (Form 1040).
High-Income Taxpayers
The Pease limitation on itemized deductions is suspended for 2010, allowing taxpayers of all income levels to claim full itemized deductions without reduction. This creates a particularly favorable environment for high-income earners who would face limitations in other years.
Temporary Provisions
The new motor vehicle tax deduction and the Pease limitation suspension are temporary provisions specific to 2010 and do not apply to subsequent tax years. Refer to the current-year instructions for returns filed for years after 2010.
