Form 1040 (2017) Tax Year Checklist
Year-Specific Context
The 2017 Form 1040 requires the reporting of ACA shared responsibility payments (line 61) and includes exemption phaseout thresholds specific to 2017. Disaster relief provisions apply to Hurricanes Harvey, Irma, and Maria, as well as the California wildfires.
Applicable 2017 Programs
The Affordable Care Act requires reporting of health coverage status or filing Form 8965 to claim exemptions for shared responsibility. Qualified disaster loss provisions allowed enhanced standard deductions without a 10% AGI floor for affected taxpayers (see Publication 976).
10-Step Checklist
Step 1: Verify Filing Status
Confirm status as of December 31, 2017. If claiming age 65+, verify birth before January 2, 1953. Married couples filing jointly confirm non-divorce status at year-end.
Step 2: Gather Income Documents
Collect all Forms W-2, W-2G, 1099-R (with box two tax withheld), 1099-INT, 1099-DIV, 1099-MISC, 1099-G, and Schedule K-1 (partnerships, S corps, trusts).
Step 3: Report Wages and Income
Enter wages (line 7), taxable interest (line 8a), ordinary dividends (line 9a), qualified dividends (line 9b), capital gains/losses (line 13).
Step 4: Claim Adjustments to Income
Report educator expenses (line 23), health savings account deduction (line 25), self-employment tax deduction (line 27), IRA deduction (line 32), student loan interest (line 33). Line 34 was reserved for future use in 2017; the tuition and fees deduction was not available for tax year 2017 unless Congress extended it. Calculate AGI (line 38).
Step 5: Select Deduction Method
Apply 2017 standard deduction (Single/MFS: $6,350; MFJ/QW: $12,700; HOH: $9,350) on line 40. Add $1,250 per person if age 65+ or blind for married filing jointly or qualifying widow(er); add $1,550 for single or head of household filers if age 65+ or blind (line 39a boxes). OR attach Schedule A for itemized deductions (required if itemized deductions exceed standard).
Step 6: Claim Exemptions
Multiply $4,050 by total exemptions (line 6d) if AGI does not exceed $156,900. If AGI exceeds the thresholds ($156,900 for MFS, $261,500 for single, $287,650 for HOH, and $313,800 for MFJ), exemptions phase out according to the worksheet in the instructions.
Step 7: Calculate Taxable Income
Subtract line 42 (exemptions) from line 41 (income minus deductions). Enter the results on line 43. If line 42 exceeds the length of line 41, enter zero.
Step 8: Compute and Report Tax
Calculate tax on line 44 using 2017 tax tables or worksheet (four filing status columns provided). Attach Form 6251 for alternative minimum tax (line 45). Attach Form 8962 if advance premium tax credits were received (line 46).
Step 9: Claim Credits and Health Coverage
Report credits (lines 48–54): foreign tax, child/dependent care, education, retirement savings, child tax, and residential energy. Check “full-year coverage” box (line 61) OR attach Form 8965 for exemption claims or shared responsibility payment. Add payment and refundable credits (lines 64–73) on line 74.
Step 10: Calculate Refund/Amount Owed and File
Subtract line 74 from line 63 (if negative, line 75 is a refund). Subtract line 63 from line 74 (if negative, line 78 is the amount owed)—sign and date return. Mail paper return to the address determined by state residency per 2017 Form 1040, Where To File page; due date April 17, 2018 (April 15 was Sunday; Emancipation Day observed April 16, 2018 in DC).

Form-Specific Limitations
Nonresident aliens must file Form 1040NR (or 1040NR-EZ if eligible); they cannot claim the earned income credit without a qualifying child unless meeting special nonresident rules. Dependents claimed on another person’s return cannot claim a personal exemption for themselves. Certain credits phase out at 2017 AGI thresholds stated in the credit instructions.
Required Schedules
Itemized deductions (Schedule A), business income (Schedule C), capital gains (Schedule D), rental/royalty income (Schedule E), self-employment tax (Schedule SE), education credits (Form 8863), adoption credit (Form 8839), health coverage exemptions (Form 8965), child tax credit if income exceeds thresholds (Schedule 8812).
2017 Disaster Relief Provisions
Taxpayers affected by Hurricanes Harvey, Irma, or Maria or California wildfires may qualify for special tax treatment under qualified disaster loss provisions. Enhanced casualty loss deductions were available without the 10% AGI floor for areas affected by the disaster. Consult Publication 976 and IRS disaster relief announcements for specific guidance on qualified disaster areas and eligible relief measures.
Health Coverage Reporting Requirements
Line 61 requires taxpayers to indicate whether they and all household members had qualifying health insurance coverage for the entire 2017 calendar year. If coverage was not maintained for the whole year, taxpayers must either claim an exemption by attaching Form 8965 or calculate and report the shared responsibility payment. The 2017 shared responsibility payment is the greater of 2.5% of household income above the filing threshold or a flat dollar amount ($695 per adult, $347.50 per child under 18, with a maximum of $2,085 per family).
Premium Tax Credit Reconciliation
Taxpayers who received advance payments of the premium tax credit through the Health Insurance Marketplace in 2017 must complete Form 8962 to reconcile advance payments with the actual premium tax credit based on final household income. Form 1095-A (Health Insurance Marketplace Statement) must be obtained from the Marketplace and used to complete Form 8962. Failure to reconcile may result in reduced or delayed refunds and impact eligibility for future advance credit payments.

Exemption Phaseout Thresholds
For 2017, personal and dependent exemptions begin to phase out when AGI exceeds specific thresholds based on filing status. The phaseout starts at $156,900 (married filing separately), $261,500 (single), $287,650 (head of household), and $313,800 (married filing jointly or qualifying widow[er]). Exemptions are reduced by 2% for each $2,500 (or portion thereof) that AGI exceeds the applicable threshold. Use the exemption phaseout worksheet in the Form 1040 instructions to calculate reduced exemption amounts.
