Selecting the right tax year is crucial for businesses and individuals. It affects when income is reported and deductions are claimed, impacting overall tax liability. This section covers the types of tax years, how to choose or change them, and the implications for tax planning.

Understanding tax year options helps optimize financial strategies. Calendar years are common, but fiscal and short tax years offer flexibility for specific situations. The 52-53 week tax year provides unique benefits for certain businesses, aligning financial reporting with natural business cycles.

Tax Year Types

Calendar, Fiscal, and Short Tax Years

• Calendar tax year spans 12 months ending on December 31st
  • Aligns with standard calendar year
  • Most common for individuals and many businesses
• Fiscal tax year covers any 12-month period ending on the last day of any month except December
  • Often used by businesses to align with natural business cycle (retail companies ending January 31st after holiday season)
• Short tax year lasts less than 12 months
  • Typically occurs when a business starts or ends operations mid-year
  • Requires special considerations for income and deduction calculations
    • Often involves annualizing income to determine tax liability

Special Considerations for Short Tax Years

• Income and deduction calculations require adjustments
  • Annualization of income necessary to determine accurate tax liability
  • Formula: $(Income ÷ Number of months in short year) × 12 = Annualized income$
• Deductions may need to be prorated based on the length of the short tax year
• Tax credits might be adjusted proportionally to the length of the short year
• Filing deadlines may differ from standard tax years
  • Generally due on the 15th day of the 4th month following the end of the short tax year

Tax Year Adoption and Change

Adopting a Tax Year

• New businesses must adopt a tax year when filing first income tax return
  • Consider factors like natural business cycle and ownership structure
• Certain entities face restrictions on tax year choice
  • S corporations generally required to use calendar year
  • Partnerships and personal service corporations have specific rules
    • Often tied to tax years of owners

Changing Tax Years

• Existing businesses must retain established tax year unless obtaining IRS approval for change
• Form 1128 used to request tax year change
  • Filing deadlines vary based on type of change requested
  • Automatic approval available for certain changes (C corporation changing to calendar year)
  • Other changes require IRS review and approval
• IRS evaluates requests based on:
  • Business purpose (aligning with industry standards)
  • Income distortion (preventing manipulation of tax liability)
  • Administrative concerns (impact on IRS operations)

Impact on Income Recognition and Deductions
