Form 1040 (SP) ANEXO 1: Ingreso Adicional y Ajustes al Ingreso (2022) – A Complete Guide

What Form 1040 (SP) Anexo 1 Is For

Form 1040 (SP) Schedule 1 (Anexo 1) is the Spanish-language version of Schedule 1 used with Form 1040, serving as a supplemental form that captures income and deductions that don't fit on the main tax return. Think of it as an ""overflow"" form for your tax return—if you have income beyond regular wages or qualify for certain deductions, Schedule 1 is where you report them.

The form has two main parts. Part I (Ingreso Adicional) captures additional income sources like unemployment compensation, business income, alimony received, rental income, gambling winnings, jury duty pay, and various other types of income that aren't reported directly on Form 1040. Part II (Ajustes al Ingreso) lists adjustments that reduce your income before calculating your tax, including educator expenses, student loan interest, IRA contributions, self-employment tax deductions, and health savings account contributions.

The total from Part I flows to line 8 of your Form 1040, adding to your total income. The total from Part II flows to line 10 of Form 1040, reducing your income to arrive at your adjusted gross income (AGI). Your AGI is crucial because it determines your eligibility for many tax credits and deductions.

According to the IRS Form 1040 instructions, you need Schedule 1 if you have additional income such as unemployment compensation, business or farm income, prize money, or if you have adjustments to income like educator expenses, student loan interest, or self-employment tax.

When You’d Use Form 1040 (SP) Anexo 1 (Late Filing/Amended Returns)

You must file Schedule 1 along with your Form 1040 by the tax return deadline. For tax year 2022, the deadline was April 18, 2023 (extended from the usual April 15 due to the Emancipation Day holiday in Washington, D.C.). If you're filing late and need more time, you can request an automatic six-month extension using Form 4868, which gives you until October 16, 2023 to file. However, it's important to understand that an extension to file is not an extension to pay—any taxes owed are still due by April 18, and you'll owe interest and potentially penalties on unpaid amounts after that date.

If you discover errors on your Schedule 1 after filing your original return, you'll need to file an amended return using Form 1040-X (Amended U.S. Individual Income Tax Return). Good news: you can now file Form 1040-X electronically for the current year and two prior tax years, making the amendment process faster and more convenient. When amending, you must include a corrected Schedule 1 with the proper amounts. Generally, you have three years from the date you filed your original return (or two years from when you paid the tax, whichever is later) to file an amended return if you're claiming a refund.

Common reasons people amend their Schedule 1 include forgetting to report unemployment compensation, discovering additional income they didn't initially report, realizing they qualify for adjustments they didn't claim (like educator expenses or student loan interest), or correcting amounts that were reported incorrectly. The IRS Form 1040-X page provides detailed guidance on the amendment process.

Key Rules or Details for the 2022 Tax Year

Several important rules govern Schedule 1. First, you must report all income shown on the form in U.S. dollars, even if you received it in foreign currency. Every line on Schedule 1 corresponds to specific types of income or adjustments, and you must use the correct line for each item—putting income or adjustments on the wrong line can delay processing or trigger IRS notices.

For alimony, critical rules changed in 2019. Only alimony received or paid under divorce or separation agreements executed before December 31, 2018 (or modified after that date with specific language including the payment as income/deduction) is reportable on Schedule 1. If your divorce agreement was finalized in 2019 or later, alimony is generally not taxable to the recipient or deductible by the payer. When reporting alimony received (line 2a) or paid (line 19a), you must provide the date of the original divorce or separation agreement and, if paying alimony, the recipient's Social Security number.

For self-employment income on line 3, you must attach Schedule C if you operated a business. If you had net earnings from self-employment of $400 or more, you're also required to pay self-employment tax using Schedule SE, and half of that tax becomes an adjustment on Schedule 1, line 15. Unemployment compensation must be fully reported on line 7—it's taxable income even though no tax may have been withheld when you received it.

Student loan interest deduction (line 21) has income phase-out limits. For 2022, the deduction begins phasing out if your modified adjusted gross income exceeds $70,000 ($145,000 for married filing jointly) and is completely eliminated at $85,000 ($175,000 for joint filers). The maximum deduction is $2,500. You cannot claim this deduction if your filing status is married filing separately or if someone else can claim you as a dependent.

IRA deduction rules (line 20) are complex and depend on whether you (or your spouse if married) are covered by a retirement plan at work. If you're not covered by a workplace plan, you can generally deduct the full contribution (up to $6,000 for 2022, or $7,000 if age 50 or older). If you are covered, deduction limits phase out based on your income according to worksheets in the IRS instructions.

Step-by-Step (High Level)

Step 1: Gather your documents

Collect all Forms W-2, 1099s (especially 1099-G for unemployment, 1099-INT, 1099-MISC, 1099-NEC for business income), receipts for deductible expenses, and records of any other income or adjustments you'll report.

Step 2: Complete Part I — Additional Income (lines 1-10)

Work through each line in order. Report state and local income tax refunds on line 1 if they're taxable (use the worksheet in the instructions to determine the taxable amount). Enter alimony received on line 2a with the date of your divorce agreement. Report business income or loss from Schedule C on line 3. Include any other gains or losses from Form 4797 on line 4. Report rental and royalty income from Schedule E on line 5, and farm income from Schedule F on line 6. Enter unemployment compensation on line 7 as shown on Form 1099-G. Lines 8a through 8z capture various types of ""other income""—carefully review each category and report amounts that apply to you, such as gambling winnings, jury duty pay, prizes, hobby income, or cancellation of debt. Add up lines 1 through 7 plus line 9 (total of lines 8a-8z) and enter the result on line 10.

Step 3: Transfer line 10 to Form 1040

Take the amount from Schedule 1, line 10, and enter it on line 8 of your Form 1040 (or 1040-SR). This adds your additional income to your total income.

Step 4: Complete Part II — Adjustments to Income (lines 11-26)

Enter qualified educator expenses on line 11 (up to $300 per eligible educator, or $600 if both you and your spouse qualify). Report certain business expenses on line 12 if you're a reservist, performing artist, or fee-basis government official. Enter health savings account deductions on line 13, and moving expenses on line 14 if you're an active-duty military member. Report half your self-employment tax from Schedule SE on line 15. Enter self-employed health insurance premiums on line 17, early withdrawal penalties on line 18, and qualifying alimony paid on line 19a (with recipient's SSN and divorce date). Report IRA deductions on line 20 and student loan interest on line 21 (up to $2,500). Lines 24a through 24z capture other adjustments like jury duty pay given to your employer, reforestation expenses, and attorney fees for certain discrimination claims. Total lines 11 through 23 plus line 25 (total of lines 24a-24z) and enter the result on line 26.

Step 5: Transfer line 26 to Form 1040

Take the amount from Schedule 1, line 26, and enter it on line 10 of your Form 1040 (or 1040-SR). This reduces your income, helping you arrive at your adjusted gross income (AGI).

Step 6: Attach Schedule 1 to your tax return

When filing electronically, the software automatically includes Schedule 1. If mailing a paper return, attach Schedule 1 behind Form 1040 in sequence number order (Schedule 1 is sequence number 01, as shown in the upper right corner of the form).

Common Mistakes and How to Avoid Them

The IRS Tax Topic 303 checklist highlights common errors that delay tax return processing. Many Schedule 1 mistakes fall into these categories.

Forgetting to attach Schedule 1 entirely.

If you have amounts to report but don't attach the schedule, the IRS will send you a notice requesting the missing form, delaying your refund. Solution: Always attach Schedule 1 when you have additional income or adjustments, even if you think the amounts are small.

Reporting income on the wrong lines.

Taxpayers sometimes put business income on line 8z (""Other income"") instead of line 3 where it belongs, or they report unemployment on the wrong line. Each income type has a designated line for tracking and processing purposes. Solution: Carefully read the line descriptions and use the appropriate line for each income type. The instructions provide detailed guidance for every line.

Math errors when totaling lines.

Adding up lines 8a through 8z to get line 9, or totaling Part II to get line 26, seems simple but math mistakes are surprisingly common and cause processing delays. Solution: Double-check all addition. Better yet, file electronically—tax software does the math automatically and flags inconsistencies before you submit.

Missing Social Security numbers or dates for alimony.

If you pay or receive alimony, you must provide the recipient's Social Security number (when paying) and the date of the original divorce agreement. Missing information here triggers automatic IRS correspondence. Solution: Have your divorce papers handy and verify the exact date and your ex-spouse's Social Security number before filing.

Claiming student loan interest when you don't qualify.

Common disqualifications include filing status of married filing separately, being claimed as someone else's dependent, or having income above the phase-out limits. Solution: Use the worksheet in the instructions to verify you qualify and calculate the correct deduction amount. If your income is borderline, the worksheet is essential.

Reporting the wrong portion of Social Security or retirement income.

Some retirement income goes on Schedule 1 (like distributions from nonqualified plans, line 8t) while other retirement income goes directly on Form 1040. Mixing these up is a common error. Solution: Match the income type on your 1099-R with the specific instructions for where to report it.

Not understanding Form 1099-K reporting.

Starting in 2022, new reporting requirements meant more people received Form 1099-K for payments received electronically. If you sold personal items at a loss (like used furniture), you may need to report the sale to show it's not taxable income, even though you had no gain. Solution: If you receive Form 1099-K for personal item sales, follow the special instructions on lines 8z and 24z to properly report the transaction without increasing your tax.

Electronic filing prevents many errors.

The IRS strongly encourages e-filing because tax software performs automatic error-checking, calculates math accurately, and prompts you for missing information. According to IRS statistics, electronic returns have significantly fewer errors than paper returns.

What Happens After You File

Once you submit your Form 1040 with Schedule 1, the IRS processing begins. If you filed electronically, you'll typically receive an acknowledgment within 24-48 hours confirming the IRS accepted your return. Paper returns take longer—the IRS receives them via mail, scans them, and manually enters the data, which can take several weeks.

The IRS processes returns in the order received. If everything on your return is accurate and complete, processing typically takes about 21 days for electronic returns or six to eight weeks for paper returns. You can check your refund status using the ""Where's My Refund?"" tool on IRS.gov or the IRS2Go mobile app. You'll need your Social Security number, filing status, and exact refund amount to check status.

If your return includes Schedule 1 with certain credits like the Earned Income Credit or Additional Child Tax Credit, the IRS holds refunds until mid-February by law, even if you file in January. This holding period allows the IRS to conduct additional verification to prevent fraud.

The IRS reviews your Schedule 1 entries against information they receive from employers, banks, and other third parties on Forms W-2, 1099, and similar documents. If the IRS finds discrepancies—for example, you reported $5,000 in unemployment but Form 1099-G shows $6,000—they'll send you a notice (usually a CP2000) proposing changes. You have the right to respond, agree to the changes, or dispute them with supporting documentation.

If you're due a refund, you'll receive it either by direct deposit (typically within 21 days) or paper check (which takes longer). If you owe additional tax, you'll receive a bill with payment instructions. If you can't pay the full amount, contact the IRS to discuss payment plan options—acting quickly can help you avoid or reduce penalties.

Sometimes the IRS selects returns for audit. Having Schedule 1 doesn't make audit more likely, though certain items (like large business losses, substantial gambling winnings, or unusually high deductions relative to income) may trigger additional scrutiny. Most audits are handled by mail—the IRS requests documentation for specific items, you provide it, and they make a determination.

Keep copies of your filed return, Schedule 1, and all supporting documents for at least three years (longer if you have special circumstances like claiming a loss from worthless securities or filing a claim for a credit or refund after you filed your original return). You may need these records to respond to IRS inquiries, prepare future returns, or file amended returns.

FAQs

Do I need to file Schedule 1 if I only have income from my regular job?

If your only income is wages, salaries, and tips reported on Form W-2, and you don't have any adjustments to income like educator expenses or student loan interest, you don't need Schedule 1. You can file Form 1040 by itself. However, if you have even one dollar of unemployment compensation, business income, or any other type of additional income—or if you qualify for any adjustment—you must include Schedule 1.

I received unemployment benefits in 2022. Do I have to pay taxes on that money?

Yes, unemployment compensation is fully taxable federal income. Report the amount shown on Form 1099-G, box 1, on Schedule 1, line 7. Many states don't automatically withhold federal income tax from unemployment benefits, so you may owe tax when you file. You can request withholding when you apply for benefits or make estimated tax payments during the year to avoid owing a large amount at tax time.

Can I deduct my student loan interest if my parents are paying my loan?

Generally, you can only deduct student loan interest that you're legally obligated to pay and that you actually paid. If your parents make payments on your behalf and you're the one legally obligated under the loan (your name is on the promissory note), you may be able to claim the deduction. However, if someone else can claim you as a dependent, you cannot take the student loan interest deduction. The loan must have been taken out solely to pay qualified education expenses for you, your spouse, or your dependent.

What's the difference between an adjustment to income and a tax deduction?

Adjustments to income (reported on Schedule 1, Part II) reduce your income before calculating your adjusted gross income (AGI), which makes them particularly valuable because they reduce both your taxable income and your AGI. Many credits and deductions phase out based on AGI, so adjustments can help you qualify for other tax benefits. Standard or itemized deductions come after AGI and only reduce your taxable income. Think of adjustments as ""above-the-line"" deductions that everyone can take if they qualify, regardless of whether they itemize.

I'm self-employed. What expenses can I deduct on Schedule 1?

Self-employed individuals don't deduct business expenses directly on Schedule 1. Instead, you'll use Schedule C to calculate your business income or loss (reporting all income and subtracting all ordinary and necessary business expenses). The net profit or loss from Schedule C then flows to Schedule 1, line 3. However, Schedule 1 Part II does give you several self-employment-related adjustments: half your self-employment tax (line 15), contributions to self-employed retirement plans like SEP-IRAs (line 16), and self-employed health insurance premiums (line 17). These adjustments further reduce your taxable income beyond the business deductions you already claimed on Schedule C.

What happens if I forget to include Schedule 1 and only send Form 1040?

The IRS will notice that your Form 1040 shows amounts on lines 8 or 10 (where Schedule 1 totals flow to) but you didn't attach the schedule explaining those amounts. They'll send you a letter requesting Schedule 1. This delays processing and your refund. In some cases, if the IRS has information returns (like a 1099-G showing unemployment) that you didn't report, they may send a notice proposing to add that income to your return and assessing additional tax, interest, and penalties. That's why it's crucial to include all required schedules with your original return.

Can I e-file the Spanish version of Schedule 1, or do I have to mail it?

The Spanish-language forms (Form 1040-SP and ANEXO 1) are primarily for taxpayers who prefer instructions and form labels in Spanish, but the IRS systems process returns in English. Many tax software programs allow you to prepare your return in Spanish and will convert the information to the English-format forms for electronic filing. If you prepare a paper return using the Spanish forms, you can mail it to the IRS—they'll process it. However, e-filing is faster, more accurate, and gets you your refund quicker. Check with your tax software provider about Spanish-language preparation options with electronic filing.
