💰Federal Income Tax Accounting Unit 6 – Itemized Deductions: Personal Tax Breaks

Itemized deductions offer taxpayers a way to reduce taxable income by claiming specific expenses. These deductions, reported on Schedule A, include medical costs, state and local taxes, mortgage interest, and charitable donations, each subject to various limitations and requirements. The Tax Cuts and Jobs Act of 2017 significantly impacted itemized deductions, increasing standard deduction amounts and modifying rules for specific deductions. Understanding these changes helps taxpayers decide between itemizing and taking the standard deduction to minimize their tax liability.

What Are Itemized Deductions?

  • Allow taxpayers to reduce their taxable income by deducting certain expenses
  • Must be elected by the taxpayer instead of taking the standard deduction
  • Reported on Schedule A of Form 1040
  • Generally beneficial for taxpayers with significant deductible expenses
  • Include expenses such as medical and dental costs, state and local taxes, mortgage interest, and charitable donations
  • Require detailed record-keeping and documentation to substantiate the deductions claimed
  • Subject to various limitations and phase-outs based on the taxpayer's income level and filing status

  • Casualty and theft losses attributable to federally declared disasters
  • Miscellaneous deductions no longer allowed under the Tax Cuts and Jobs Act (TCJA) of 2017

Standard vs. Itemized: Which to Choose?

  • Taxpayers must choose between itemizing deductions or taking the standard deduction
  • The standard deduction is a fixed amount based on filing status (single, married filing jointly, head of household)
  • Itemizing is beneficial when the total of itemized deductions exceeds the standard deduction
  • Factors to consider include the taxpayer's income level, filing status, and the nature and amount of deductible expenses
  • The TCJA significantly increased the standard deduction amounts, making itemizing less advantageous for many taxpayers
  • Taxpayers should calculate their taxes using both methods to determine which results in a lower tax liability

Calculating Itemized Deductions

  • Begin by gathering all relevant documentation, such as receipts, invoices, and bank statements
  • Categorize expenses according to the type of itemized deduction (medical, taxes, interest, charitable contributions)
  • Apply any applicable limitations or thresholds to each category (e.g., medical expenses must exceed 7.5% of AGI)
  • Sum the allowed deductions from each category to determine the total itemized deductions
  • Compare the total itemized deductions to the standard deduction for the taxpayer's filing status
  • If itemized deductions exceed the standard deduction, enter the total on Schedule A and attach it to Form 1040
  • If the standard deduction is higher, claim the standard deduction on Form 1040 instead
