• Total Income (Form 1040, Line 9)

  • Income from all sources, regardless of type. In this case, total income amounted to $246,695 between wages, interest, dividends, IRA distributions, capital gains, self-employment income, and rental income.

• Schedule 1 Adjustments (Form 1040, Line 10)

  • “Above the line” deductions (aka deductions for AGI). Specific to this return, Paula can deduct half of her self-employment tax ($3,738) in Schedule 1 adjustments to income. Other common adjustments on Schedule 1 include the health savings account (HSA) deduction, self-employed health insurance deduction, contributions to SEP, SIMPLE, and qualified plans, deductible IRA contributions, student loan interest deductions, and educator expenses, among others.
• Adjusted Gross Income (AGI) (Form 1040, Line 11)
  • Total income after the adjustments from Part II of Schedule 1. In this case, after Schedule 1 adjustments of $3,738, Peter and Paula's AGI was $242,757.

• Standard or Itemized Deductions (Form 1040, Line 12)

  • Either the standard deduction allowable to all taxpayers or the amount of itemized deductions, whichever is higher.
    
    • The standard deduction is determined by filing status; in 2025, the standard deduction for married filing jointly (MFJ) taxpayers was $31,500, as seen in the descriptive box to the left of Line 12e on Form 1040. Individuals over age 65 and/or who are blind can add additional deductions to the standard deduction, and elect those additional deductions by checking the boxes on line 12d.
    • Itemized deductions most commonly include:
      • • Medical expenses above 7.5% of AGI
        • State and local taxes (income, property, real estate, etc.), capped at $40,000 and subject to MAGI limitations
        • Mortgage interest
        • Charitable contributions 
      • Less commonly, taxpayers can also deduct investment interest expenses (in certain cases), casualty and theft losses, and income in respect of a decedent (resulting from estate tax paid that was attributable to assets in qualified retirement accounts inherited by the taxpayer). 
      • Itemized deductions are captured on Schedule A.
    • Because Peter and Paula's itemized deductions of $46,500 exceed the standard deduction amount, they took the itemized deduction in 2025.

• Taxable Income (Form 1040, Line 15)

  • Adjusted Gross Income less deductions from AGI. This is the amount that is used to calculate the actual tax bill.
    • For many taxpayers, deductions will equal the applicable standard deduction or the total itemized deductions. 
    • Taxpayers with self-employment and/or real estate income may also be eligible for the Qualified Business Income (QBI) deduction (Form 1040, Line 13a). Paula was eligible for and took a QBI deduction of $9,832, but the default set of Key Figures does not include this amount. Users can include that deduction, along with other deductions, by customizing their Key Figures. 

• • • After the itemized deductions and the QBI deduction, Peter and Paula’s taxable income was $186,425.

• Total Tax (Form 1040, Line 24)

  • The amount of tax resulting from the taxes on ordinary income (taxable income less the qualified income eligible for the preferential long-term capital gains tax rates using the progressive marginal bracket system), qualified dividends/capital gains income (using those more preferential tax rates) and additional taxes from Schedule 2 (Self-Employment Tax), less the child tax credit and other non-refundable credits from Schedule 3.

• • Peter and Paula’s tax on ordinary income (at the marginal rates) and qualified dividends/capital gains income (at the long-term capital gains rates) amounted to $28,427 (Form 1040, Line 16).
  • Peter and Paula's "Other Taxes" (Form 1040, Line 23) totaled $7,475, which was entirely attributable to Self-Employment Tax. For some taxpayers, these "Other Taxes" may include Additional Medicare Tax and/or Net Investment Income (NIIT) Tax, among others. Taxpayers with wages and/or modified adjusted gross income over $200,000/$250,000 (single/married filing joint) have an additional 0.9% Medicare tax on wages and may have a 3.8% Net Investment Income Tax that is included as part of the total tax calculation.
  • Peter and Paula had one child over 17 (Lisa) who qualified for a $500 Other Dependent Credit (ODC). They also had a child under 17 (Bart) who qualified for the $2,200 child tax credit. Peter and Paula qualified for the full amount of the credit, but some taxpayers will have this credit amount limited due to their income. These two credits totaling $2,700 are calculated on Schedule 8812 and reported on Line 19 of Form 1040.

• • Peter and Paula had dependent care expenses for Bart, resulting in a $600 credit for child and dependent care expenses (Schedule 3, Line 2). This $600 credit is reported on Form 1040, Line 20. This credit is non-refundable, meaning it can take a taxpayer's tax obligation down to $0, but no lower than that (which would result in a refund).
  • Peter and Paula's total tax credits (child tax credit and dependent care expense credit) of $3,300 were reported on Form 1040, Line 21.

• • The net result was a total tax of $32,602 as reported on Form 1040, Line 24.
