Form 1040 U.S. Individual Income Tax Return (2012): Your Complete Guide
What Form 1040 Is For
Form 1040 is the standard federal income tax return that most Americans use to report their yearly income to the Internal Revenue Service (IRS). Think of it as your annual financial report card to the government. For the 2012 tax year, this form allowed you to calculate how much tax you owed based on your wages, investment income, business earnings, and other sources of money you received during the year. It also determined whether you'd receive a refund or owe additional taxes.
The form works by having you report all your income, subtract eligible deductions (like mortgage interest or charitable donations), apply tax credits (such as the child tax credit), and compare what you already paid through withholding or estimated payments against what you actually owe. The 2012 version was used to report income earned between January 1 and December 31, 2012, and was due by April 15, 2013.

When You’d Use Form 1040 (Including Late or Amended Returns)
Standard Filing Deadline
For 2012 returns, the standard filing deadline was April 15, 2013. However, several situations might have required you to file later or submit corrections:
Getting More Time
If you couldn't meet the April deadline, you could request an automatic six-month extension using Form 4868, giving you until October 15, 2013. Important note: an extension to file is not an extension to pay. You still owed any taxes by April 15 to avoid interest charges.
Filing Late
If you missed the deadline entirely without filing an extension, you should still file as soon as possible. The IRS charges penalties for late filing (typically 5% of unpaid taxes per month, up to 25%) and interest on unpaid taxes, making prompt filing crucial even if you're late.
Amended Returns
If you discovered errors after filing, you'd use Form 1040X (Amended U.S. Individual Income Tax Return) to make corrections. For 2012 returns, you generally had until April 15, 2016 (three years from the original deadline) to file an amended return if you wanted to claim a refund you missed. Common reasons for amendments include forgotten income forms, missed deductions, or changes to filing status.

Tax Brackets
The 2012 rates ranged from 10% to 35%. For example, a single filer paid 10% on the first $8,700 of taxable income, then 15% on income between $8,700 and $35,350, progressing up to 35% on income exceeding $388,350.

For instance, single taxpayers under 65 needed to file if their income was at least $9,750, while those 65 or older had a threshold of $11,200. Anyone with self-employment income of $400 or more had to file regardless of other income.

Step-by-Step Overview (High Level)
1. Gather Your Documents
Collect all W-2 forms from employers, 1099 forms for interest, dividends, and other income, receipts for deductible expenses, and records of estimated tax payments. Most people received these forms by late January or early February 2013.
2. Choose Your Filing Method
You could file electronically (e-file) through tax software or a tax professional, or mail a paper return. E-filing was faster, reduced errors, and typically resulted in refunds within 21 days compared to 6-8 weeks for paper returns.
3. Report Your Income
Enter wages from W-2s, interest and dividends from 1099s, business income, retirement distributions, Social Security benefits, and any other taxable income on the appropriate lines.
4. Calculate Adjustments
Subtract eligible adjustments to income (like IRA contributions, student loan interest, or educator expenses) to arrive at your adjusted gross income (AGI).
5. Determine Deductions
Choose between taking the standard deduction or itemizing deductions on Schedule A (for mortgage interest, charitable contributions, state taxes, etc.). Take whichever is larger.
6. Apply Tax Credits
Subtract credits like the child tax credit, education credits, or energy efficiency credits. Credits reduce your tax dollar-for-dollar, making them more valuable than deductions.
7. Calculate Total Tax and Payments
Figure your final tax using the tax tables or rate schedules, then subtract what you already paid through withholding and estimated payments.
8. Refund or Payment
If you overpaid, you'd receive a refund via direct deposit or check. If you owed money, you'd mail a check or pay electronically.
Common Mistakes and How to Avoid Them
Based on IRS data from the 2012 filing season, these were the most frequent errors:
Math Errors
Simple addition and subtraction mistakes caused countless processing delays. Solution: Use tax software with automatic calculations, or double-check all math with a calculator if filing by hand.
Wrong or Missing Social Security Numbers
Names and SSNs must match Social Security records exactly. Even a transposed digit caused rejections. Solution: Compare your tax forms directly against Social Security cards before filing.
Incorrect Filing Status
Choosing the wrong status (single vs. head of household, for example) affected your standard deduction and tax rates. Solution: Review the definitions carefully. For instance, head of household required you to be unmarried and pay more than half the costs of maintaining a home for a qualifying dependent.
Forgetting to Sign
Unsigned returns weren't valid. Solution: Both spouses must sign joint returns. If e-filing, you'd use a PIN to sign electronically.
Incorrect Bank Account Numbers
Errors in routing or account numbers on refund lines caused major delays. Solution: Use a voided check to verify numbers, not a deposit slip, as routing numbers can differ.
Missing Forms
Filing before receiving all income documents (some 1099s arrive late) meant understated income. Solution: Wait until late February to file, ensuring you have all forms. Check your prior year return to see what forms you typically receive.
Claiming Credits You Don't Qualify For
The earned income tax credit and education credits had complex eligibility rules. Solution: Use the IRS worksheets and publication guidelines to verify eligibility before claiming.

What Happens After You File
Understanding the post-filing process helped taxpayers know what to expect:
Processing Timeline
E-filed returns were typically processed within 21 days, while paper returns took 6-8 weeks or longer. You could check your refund status using the "Where's My Refund?" tool on IRS.gov 24 hours after e-filing or four weeks after mailing a paper return.
Refund Delivery
Direct deposit was fastest, typically arriving within three weeks of e-filing. Paper checks took several additional weeks. Refunds were issued for the amount shown on your return unless the IRS made adjustments.
IRS Correspondence
Some returns were flagged for review or minor corrections. You might receive a notice explaining adjustments, requesting additional documentation, or informing you of mathematical corrections the IRS made. Most notices weren't audits—just routine requests for clarification.
Audits
While rare (less than 1% of returns), audits could occur within three years of filing. Keeping documentation for at least three years protected you if questions arose about your 2012 return.
Amended Return Processing
Form 1040X took considerably longer—typically 8-12 weeks—because these were processed manually rather than electronically (in 2012, 1040X couldn't be e-filed).
Payment Plans
If you owed taxes you couldn't pay immediately, the IRS offered installment agreements. Applying early minimized penalties and interest charges.

FAQs
1. What if I couldn't afford to pay the taxes I owed for 2012?
You should still have filed your return by the April 15, 2013 deadline even if you couldn't pay. Filing on time avoided the steep failure-to-file penalty (5% per month). You could then set up a payment plan with the IRS, paying in monthly installments. The IRS charged interest and a smaller failure-to-pay penalty (0.5% per month), but this was far less expensive than not filing at all.
2. Could I file electronically for free for 2012?
Yes! The IRS Free File program offered free tax software to anyone whose adjusted gross income was $57,000 or less in 2012—covering about 70% of taxpayers. Those earning more could use Free File Fillable Forms, which provided basic electronic forms with automatic math calculations. Both options were available at IRS.gov/freefile.
3. What happened if I forgot to include a W-2 or 1099 form?
You needed to file an amended return (Form 1040X) to report the missing income. While the IRS would eventually catch the discrepancy through their computer matching system, voluntarily amending showed good faith and often resulted in reduced penalties. Include all missing documentation with your 1040X and explain the error.
4. How long should I keep my 2012 tax records?
The IRS recommended keeping returns and supporting documents for at least three years from the filing date, as this was the standard audit period. However, if you substantially understated income (by 25% or more), the IRS had six years to audit. For maximum protection, many tax professionals advised keeping returns permanently and supporting documents for seven years.
5. What if my circumstances changed after filing—could I change my filing status?
Filing status was generally locked in as of December 31, 2012. However, you could amend from married filing separately to married filing jointly within three years. The reverse (joint to separate) was typically not allowed after the filing deadline. If you qualified for a more beneficial status you didn't claim (like head of household), you could amend to claim it.
6. Did I have to report income from side jobs or freelance work?
Yes. All income was taxable unless specifically excluded by law. If you earned $400 or more from self-employment, you had to report it and pay self-employment tax (Social Security and Medicare taxes), even if you didn't receive a 1099 form. Many people mistakenly thought that not receiving a form meant the income wasn't taxable.
7. What if my refund amount was different from what I calculated?
The IRS would send a notice explaining any changes. Common reasons included math errors they corrected, applying your refund to past-due taxes or other government debts (like student loans), or adjusting claimed credits the IRS determined you didn't qualify for. You had the right to dispute adjustments if you disagreed, with instructions provided in the notice.
