Form 1040 (2019) Tax Return Checklist: Paper Filing
The 2019 Form 1040 redesign consolidates six prior numbered schedules into three (Schedules 1, 2, 3), adopts a building-block approach requiring only necessary attachments based on taxpayer circumstances, eliminates the health insurance shared responsibility requirement that existed in prior years, and introduces Form 1040-SR for taxpayers age 65 and older (born before January 2, 1955) as a senior-friendly alternative with larger print and standard deduction charts. This represents a significant simplification from prior years while maintaining thorough income tax reporting for all taxpayer situations.
Year-Specific Programs Applying to 2019
For 2019, taxpayers no longer file Form 8965 or make shared responsibility payments if uninsured, reflecting the elimination of the individual mandate penalty under the Tax Cuts and Jobs Act. Medical expenses remain deductible at the 7.5 percent adjusted gross income threshold, which was extended from 2018 rather than reverting to the previously scheduled 10 percent floor.
Section 179 property expensing is permitted up to $1,020,000 maximum for qualified property placed in service during 2019, with the deduction phasing out dollar-for-dollar when total property placed in service exceeds $2,550,000. Capital gain and loss reporting is now located on Form 1040, line 6, directly on the main form, rather than being reported on Schedule 1, as was the case in the 2018 transition year.
Comprehensive Ten-Step Filing Process
Step 1: Determine Filing Status and Residency
Select one filing status from the five available options: Single, Married Filing Jointly, Married Filing Separately, Head of Household, or Qualifying Widow(er) with Dependent Child. Your filing status determines your standard deduction amount, tax bracket thresholds, and eligibility for certain credits and deductions.
Nonresident aliens must file Form 1040-NR instead of Form 1040, as they are subject to different tax rules and cannot claim the standard deduction. If you were born before January 2, 1955, you may use Form 1040-SR, which offers a more accessible format with larger print and includes a standard deduction chart that takes into account your age and filing status.

Step 2: Gather Income Documents
Collect all 2019 income documents including Forms W-2 showing wages, salaries, and tips from all employers, Forms 1099-INT reporting interest income from banks and financial institutions, Forms 1099-DIV showing dividend income and capital gain distributions, Forms 1099-MISC or 1099-NEC for non-employee compensation and other miscellaneous income, Schedule K-1 forms from partnerships and S corporations showing your share of pass-through income, Forms 1099-B reporting proceeds from broker transactions and securities sales, Forms 1098-T showing qualified tuition and related expenses for education credits, and Form 1095-A if you received advance payments of the premium tax credit for health insurance purchased through the Marketplace.
Step 3: Report Total Income on Line 7b
Add wages from line 1, taxable interest from line 2b, ordinary dividends from line 3b, taxable IRA distributions from line 4b, taxable pension and annuity amounts from line 4d, taxable Social Security benefits from line 5b, capital gains or losses from line 6, and other income from Schedule 1, line 9 reported on line 7a. The sum of all these income sources equals your total income on line 7b.
This represents all income received during the tax year before any adjustments, deductions, or credits are applied. Ensure all amounts match the corresponding information documents and forms received from payers.
Step 4: Claim Adjustments to Income Using Schedule 1
Suppose you have adjustments to income, complete Schedule 1, Part II. Eligible adjustments include educator expenses for qualified K-12 teachers, the deductible portion of self-employment tax calculated on Schedule SE, health savings account deductions, IRA contributions subject to income limitations, student loan interest deduction subject to a modified adjusted gross income phase-out, and deductible tuition and fees.
Report the total of all adjustments on Form 1040, line 8a. Subtract line 8a from line 7b to calculate adjusted gross income on line 8b. Adjusted gross income serves as the baseline for calculating various deductions and credit limitations.
Step 5: Claim Standard or Itemized Deduction
For 2019, the standard deductions are as follows: Single, $12,200; Married Filing Jointly or Qualifying Widow(er), $24,400; Head of Household, $18,350; and Married Filing Separately, $12,200.
If you or your spouse is age 65 or older, or blind, you may claim an additional standard deduction amount of $1,300 for married taxpayers or $1,650 for unmarried taxpayers. Alternatively, if your total itemized deductions exceed your standard deduction amount, itemize deductions on Schedule A.
Itemized deductions include medical expenses exceeding 7.5 percent of adjusted gross income, state and local taxes up to $10,000, mortgage interest, charitable contributions, and casualty and theft losses from federally declared disasters. Enter your total deduction amount on line 9.
Step 6: Claim Qualified Business Income Deduction if Applicable
Suppose you have qualified business income from Schedule C sole proprietorship, Schedule E rental real estate or pass-through entities, Schedule F farming operations, or K-1 income from partnerships and S corporations. In that case, you may be eligible for the qualified business income deduction under Section 199A.
Attach Form 8995 if your taxable income before the QBI deduction is at or below $160,700 for single filers or $321,400 for married filing jointly. If your income exceeds these thresholds, use Form 8995-A, which applies W-2 wage and qualified property limitations. The deduction is generally limited to 20 percent of qualified business income or 20 percent of taxable income before the QBI deduction, whichever is smaller. Enter the calculated deduction on line 10.
Step 7: Calculate Tax on Line 12a
Use the 2019 tax tables provided in the Form 1040 instructions corresponding to your filing status and taxable income shown on line 11b. For taxpayers with qualified dividends or capital gains, use the Qualified Dividends and Capital Gain Tax Worksheet to calculate tax using preferential rates.
Check whether any income comes from Form 8814 for reporting a child’s interest and dividends, Form 4972 for lump-sum distributions from qualified retirement plans, or other specified sources requiring special tax calculation worksheets. Enter the calculated tax amount on line 12a. This represents your tentative tax before credits are applied.
Step 8: Claim Credits Using Line 13a and Schedule 3
Report child tax credit or credit for other dependents on line 13a. The Child Tax Credit provides up to $2,000 per qualifying child under the age of 17, with up to $1,400 being refundable as the Additional Child Tax Credit if your credit exceeds your tax liability. Attach Schedule 8812 if claiming the additional child tax credit.
Use Schedule 3, Part I, for nonrefundable credits, including foreign tax credit on line 1, education credits from Form 8863 on line 3, and other nonrefundable credits.
Schedule 3, Part II, reports certain payments and refundable credits, such as estimated tax payments, net premium tax credit, and the amount paid with an extension. Report earned income credit on Form 1040, line 18a, supported by Schedule EIC if claiming qualifying children. Report American Opportunity Tax Credit on Form 1040, line 18c, from Form 8863.
This checklist is for educational purposes only and does not constitute tax or legal advice. Always review official IRS instructions and consult a qualified professional for guidance.
Step 9: Report Other Taxes and Payments
Complete Schedule 2 if you owe self-employment tax calculated on Schedule SE, household employment taxes from Schedule H, alternative minimum tax from Form 6251, excess advance premium tax credit repayment from Form 8962, or other taxes specified in the instructions—report total withholding from all Forms W-2 and Forms 1099 on lines 17 and 18e.
Enter estimated tax payments made during 2019, including any overpayment from 2018 that you applied to 2019. The total of all fees and refundable credits should be calculated and verified against your total tax liability to determine whether you have an overpayment or balance due.
Step 10: Verify and Sign Under Penalty of Perjury
Reconcile line 16 showing total tax with line 19 showing total payments. If line 19 exceeds line 16, you have an overpayment. Enter the overpayment amount on line 20.
Indicate the portion you want refunded on line 21a, and if you prefer direct deposit, provide your routing and account numbers on lines 21b through 21d. If you're going to apply any portion to your 2020 estimated tax, enter that amount on line 22. If line 16 exceeds line 19, you owe additional tax.
Enter the amount owed on line 23. Sign and date Form 1040 with both spouses signing if filing jointly. Attach all required schedules in sequence: Schedules 1, 2, and 3, followed by lettered schedules (e.g., Schedule A, Schedule B, Schedule C, Schedule D, Schedule E, and Schedule SE) in alphabetical order.
Retain a complete copy of your return and all supporting documents for your records. See IRS Form 1040 (2019) instructions for where to file paper returns based on your state of residence and whether you are enclosing a payment.
Key Form Changes for 2019
The schedule structure underwent a significant redesign in 2019, consolidating six numbered schedules into three, with additional income and adjustments in Schedule 1, additional taxes in Schedule 2, and credits and payments in Schedule 3.
Capital gain and loss reporting was moved from Schedule 1, line 13, in 2018 to Form 1040, line 6, in 2019, placing this common income item directly on the main form. Pensions and annuities were received separately, with explicit lines 4c and 4d in 2019, distinguished from IRA distributions on lines 4a and 4b, providing more transparent reporting of retirement income sources.
The health insurance shared responsibility requirement was removed entirely. The 2018 form required taxpayers to answer a full-year coverage checkbox, and Form 8965 was required if applicable to report coverage exemptions or calculate the individual shared responsibility payment. In 2019, this box was removed, and Form 8965 is no longer necessary, reflecting the elimination of the individual mandate penalty.
Standard deduction amounts were updated for 2019 to Single $12,200, Married Filing Jointly $24,400, and Head of Household $18,350 for head of household, representing inflation adjustments from the 2018 amounts.

Form-Specific Limitations
Nonresident aliens cannot claim the standard deduction and must file Form 1040-NR following different rules for income sourcing, deductions, and credits. Dependent filers have their standard deduction limited to the greater of $1,100 or their earned income plus $350, up to the full standard deduction amount for their filing status, with modifications for age and blindness.
Married filers who file separately face additional limitations: if one spouse itemizes deductions, the other spouse must also itemize and cannot claim the standard deduction. Form 1040 requires the attachment of all applicable schedules and supporting forms based on the taxpayer's circumstances, including Schedules 1, 2, and 3 when appropriate, as well as forms such as Form 8814, Form 8863, Form 8962, Form 8995, Schedule SE, and others as required by the specific tax situation.
Conclusion
Completing the 2019 Form 1040 requires systematic gathering of all income documents, careful calculation of adjustments and deductions, proper application of available credits, and accurate reconciliation of payments against tax liability. The redesigned building-block approach simplifies the form for taxpayers with straightforward situations while maintaining comprehensive reporting capabilities through targeted schedules and attachments.
Understanding the elimination of the health insurance shared responsibility requirement, the continued availability of the qualified business income deduction, and the proper sequencing of schedules and forms ensures accurate and complete tax reporting for the 2019 tax year.
