Purpose
Form 1040 is the U.S. Individual Income Tax Return for the calendar year January 1–December 31, 2014. This tax year introduced significant health insurance reporting requirements under the Affordable Care Act (ACA). Filers must indicate full-year health coverage by checking box 61, claim a coverage exemption, or calculate a shared responsibility payment. These ACA provisions applied to tax years 2014–2018 and represent a material change from prior filing years.
Step-by-Step Completion Guide
Step 1: Verify Personal Information
Ensure your name, Social Security Number (SSN), and spouse’s SSN (if filing jointly) match IRS records exactly. Verify birth dates for age-based determinations: taxpayers born before January 2, 1950, qualify for additional standard deduction amounts. For joint returns, both spouses must sign the same document.
Step 2: Select Your Filing Status
Choose one of five filing statuses: single, married filing jointly, married filing separately, head of household, or qualifying widow(er) with dependent child. If filing jointly, enter your spouse’s full legal name. Your filing status determines your standard deduction amount and the tax rates applicable to you.
Step 3: Claim Your Exemptions
On line 6a, claim yourself unless another taxpayer claims you as a dependent. On line 6b, claim your spouse if filing jointly. On line 6c, list all dependents with their SSN, relationship, and check box 6c(4) for children under age 17 who qualify for the child tax credit. The 2014 exemption amount is $3,950 per person. Enter the total number of exemptions on line 6d.
Step 4: Report All Income Sources
Report income on the designated lines: wages from Form W-2 (line 7), taxable interest (line 8a), ordinary and qualified dividends (lines 9a–9b), taxable refunds (line 10), alimony received (line 11), business income from Schedule C (line 12), capital gain or loss from Schedule D (line 13), other gains or losses from Form 4797 (line 14), IRA distributions (lines 15a–15b), pensions and annuities (lines 16a–16b), rental and partnership income from Schedule E (line 17), farm income from Schedule F (line 18), unemployment compensation (line 19), Social Security benefits (lines 20a–20b), and other income (line 21). Attach all required schedules, Forms W-2, W-2G, and 1099-R showing tax withholding.
Step 5: Calculate Adjusted Gross Income (AGI)
Add all income from lines 7–21 and enter the total on line 22. Subtract the above-the-line deductions from lines 23 to 35. These include educator expenses, certain business expenses, the health savings account deduction, moving costs, half of the self-employment tax, contributions to SEP/SIMPLE/qualified retirement plans, self-employed health insurance, early withdrawal penalties, alimony paid, the IRA deduction, the student loan interest deduction, the tuition and fees deduction via Form 8917, and the domestic production activities deduction via Form 8903. Enter the total deductions on line 36 and subtract from line 22 to determine your AGI on line 37.
Step 6: Determine Your Standard or Itemized Deduction
Report your AGI from line 37 on line 38. Claim either the standard deduction (line 40) or itemized deductions from Schedule A. For 2014, standard deduction amounts are: $6,200 (single or married filing separately), $12,400 (married filing jointly or qualifying widow(er)), and $9,100 (head of household). Additional standard deduction applies if you were born before January 2, 1950, or are blind—check the appropriate boxes on lines 39a and 39b and add the total boxes checked.
Step 7: Calculate Taxable Income Before Exemptions
Subtract your standard or itemized deduction (line 40) from line 38 to get line 41. On line 42, multiply $3,950 by the number of exemptions from line 6d. However, exemptions begin to phase out when AGI exceeds certain thresholds: $152,525 (married filing separately), $254,200 (single), $279,650 (head of household), or $305,050 (married filing jointly/qualifying widow(er)). If your line 38 amount exceeds these limits, see the instructions for the phaseout calculation.
Step 8: Determine Your Taxable Income
Subtract line 42 from line 41 to arrive at your taxable income on line 43. If line 42 exceeds line 41, enter zero on line 43.
Step 9: Compute Your Total Tax
Calculate income tax using the tax tables or tax computation worksheet (line 44). Check box 44a if using Form 8814 or box 44b if using Form 4972. Add alternative minimum tax from Form 6251 (line 45) and excess advance premium tax credit repayment from Form 8962 (line 46). Line 46 is ACA-specific and reconciles excess premium subsidies received. Add lines 44, 45, and 46 to get your total tax on line 47.
Step 10: Apply Tax Credits
Calculate and enter available credits on lines 48–54: foreign tax credit from Form 1116 (line 48), child and dependent care credit from Form 2441 (line 49), education credits from Form 8863 line 19 (line 50), retirement savings contributions credit from Form 8880 (line 51), child tax credit and attach Schedule 8812 if required (line 52), residential energy credits from Form 5695 (line 53), and other credits from Forms 3800 or 8801 (line 54). Total all credits on line 55 and subtract from line 47 to get line 56.
Step 11: Add Other Taxes
Calculate other taxes on lines 57–62: self-employment tax from Schedule SE (line 57), unreported Social Security and Medicare tax from Forms 4137 or 8919 (line 58), additional tax on IRAs and retirement plans from Form 5329 (line 59), household employment taxes from Schedule H (line 60a), first-time homebuyer credit repayment from Form 5405 (line 60b), health care individual responsibility coverage or payment (line 61), and other taxes from Forms 8959 or 8960 (line 62). Add lines 56 through 62 to determine your total tax on line 63.
Step 12: Report All Payments and Additional Credits
Enter federal income tax withheld from Forms W-2 and 1099 (line 64) and 2014 estimated tax payments, plus any amount applied to your 2013 return (line 65). Calculate earned income credit and attach Schedule EIC if you have a qualifying child (line 66a). Report additional child tax credit from Schedule 8812 (line 67), American opportunity credit from Form 8863 line 8 (line 68), net premium tax credit from Form 8962 (line 69), amount paid with extension request (line 70), excess social security and tier 1 RRTA tax withheld (line 71), credit for federal tax on fuels from Form 4136 (line 72), and credits from Form 2439 (line 73). Total all payments on line 74.
Step 13: Calculate Refund or Amount Owed
If line 74 exceeds line 63, subtract line 63 from line 74 to determine your refund (line 75). Enter the amount you want refunded on line 76a or applied to the 2015 estimated tax on line 77. For direct deposit, provide your routing number, account number, and account type. If line 63 exceeds line 74, subtract line 74 from line 63 to determine the amount you owe (line 78). Calculate any estimated tax penalty on line 79.
Step 14: Verify Health Care Coverage Requirements
On line 61, check the “Full-year coverage” box if you, your spouse (if filing jointly), and all dependents had qualifying health insurance for all twelve months of 2014. If anyone lacked coverage for any month and does not qualify for an exemption, attach Form 8965 to claim exemptions or calculate the shared responsibility payment. If advance premium tax credit payments were made, you must file Form 8962 regardless of coverage status.
Step 15: Sign, Date, and File Your Return
Both spouses must sign and date a joint return. Enter your occupation(s) and daytime phone number. If applicable, enter your Identity Protection PIN. Mail your return to the appropriate IRS address by April 15, 2015, or file electronically. Attach all required schedules, forms, and W-2s in the correct order.
Important Reminders
Health Insurance Reporting
The 2014 tax year was the first requiring ACA compliance reporting. Failure to indicate coverage, exemption, or payment may result in delayed processing.
Exemption Phaseout
High-income filers face reduced exemption benefits. The phaseout is complete when AGI reaches $275,025 (married filing separately), $376,700 (single), $402,150 (head of household), or $427,550 (married filing jointly/qualifying widow(er)).
Premium Tax Credit Reconciliation
If you or your dependents enrolled through the Health Insurance Marketplace and received advance premium payments, Form 8962 is mandatory even if you owe no tax.
Electronic Filing
IRS e-file provides faster refunds, immediate confirmation, and greater accuracy. Free File options are available for taxpayers with an AGI of $60,000 or less.
Extension to File
Form 4868 provides an automatic six-month extension to file, but does not extend the payment deadline. Interest and penalties accrue on unpaid balances after April 15, 2015.
Record Retention
Keep copies of your filed return, all supporting documents, and receipts for at least three years from the filing date.
Special Considerations
First-Time Filers
If this is your first time filing, verify your SSN is correct with the Social Security Administration before submitting your return to avoid processing delays.
Amended Returns
If you discover errors after filing, use Form 1040X to amend within three years of the original filing date or two years from when you paid the tax, whichever is later.
Combat Zone Extensions
Service members serving in designated combat zones or contingency operations receive automatic filing extensions beyond April 15, 2015. See IRS Publication 3 for details.
Nonresident Aliens
Different filing rules apply. Most nonresident and dual-status aliens are required to file Form 1040NR or Form 1040NR-EZ instead of Form 1040. Consult IRS Publication 519 for specific requirements.
Dependent Children’s Income
Parents may elect to include a child’s investment income on their return using Form 8814 if the child was under age 19 or a full-time student under age 24, had only interest and dividend income, and meets other requirements.
State Tax Returns
Most states require separate state income tax returns. Deadlines and requirements vary by state, though many states accept the federal filing deadline.
Professional Assistance
Complex tax situations involving business income, rental properties, foreign income, or significant investment transactions may benefit from professional tax preparation services or the assistance of a certified public accountant.
