Form 1040 Tax Year 2023: A Comprehensive Filing
Checklist
Overview of Tax Year 2023
The 2023 tax year continues the Tax Cuts and Jobs Act provisions, which remain effective
through 2025, including enhanced standard deductions, qualified business income deductions,
and suspended personal exemptions. The digital assets question that first appeared on the
2019 Form 1040 continues with refined terminology requiring all taxpayers to disclose digital
asset transactions.
No Economic Impact Payment reconciliation, Affordable Care Act shared responsibility
payment, or American Rescue Plan Act unemployment exclusion applies to 2023 returns. The
Earned Income Credit, Child Tax Credit, and American Opportunity Credit remain available
under current law.
Key 2023 Provisions
Standard Deduction Amounts
For 2023, standard deduction amounts are $13,850 for single filers and married filing separately,
$27,700 for married filing jointly and a qualifying surviving spouse, and $20,800 for head of
household. Taxpayers who were born before January 2, 1959, who are age sixty-five or older on
December 31, 2023, or who are blind receive additional standard deduction amounts of $1,850
for single or head of household and $1,500 for married filing jointly, married filing separately, or
qualifying surviving spouse. Taxpayers calculate these additional amounts using the worksheet
in the instructions.
Digital Asset Reporting
All taxpayers must answer the question about digital assets at the top of Form 1040. Check 'yes'
if, at any time during 2023, you received a digital asset as a reward, award, or payment for
property or services, or sold, exchanged, gifted, or otherwise disposed of a digital asset or a
financial interest in a digital asset.
Digital assets encompass cryptocurrency, stablecoins, non-fungible tokens, and other digital
representations of value stored on cryptographically secured, distributed ledgers. Check no if
your only transactions were purchases of digital assets with real currency. A "yes" answer
establishes disclosure but does not automatically create tax liability.
Child Tax Credit
For 2023, the Child Tax Credit remains $2,000 per qualifying child under age seventeen, with up
to $1,600 refundable as the Additional Child Tax Credit. The credit phases out at a modified
adjusted gross income of $400,000 for married filing jointly and $200,000 for other filing
statuses. The Credit for Other Dependents remains $500 per qualifying dependent who does
not qualify for the Child Tax Credit. Complete Schedule 8812 to calculate these credits.
Qualified Business Income Deduction
Taxpayers with qualified business income from sole proprietorships, partnerships, S
corporations, and certain rental activities may claim a deduction of up to twenty percent of their
business income. For 2023, taxpayers with taxable income at or below $364,200 for married
filing jointly or $182,100 for other filing statuses use Form 8995 for simplified calculation. Those
exceeding these thresholds or with specified service trades or businesses use Form 8995-A.
The deduction is subject to limitations based on W-2 wages and qualified property.
