Schedule CA (540) (2013): Adjustments for Residents

What Schedule CA (540) (2013) Is For

Schedule CA (540) (2013), titled California Adjustments – Residents, is used by California residents to reconcile differences between federal and state tax laws. While the Internal Revenue Service determines your federal adjusted gross income, California applies its own rules for taxable income and deductions. This form helps adjust your federal figures to reflect California-specific tax treatment, ensuring that your income tax return, filed with Form 540, accurately reflects the correct California adjusted gross income for tax purposes.

When You’d Use Schedule CA (540) (2013)

Use Schedule CA (540) (2013) whenever federal income or deductions differ from what California law allows.

• Received income treated differently by California: For example, Social Security benefits and unemployment compensation are not taxed by California, even though they may be taxable federally.
  
  
• Claimed deductions or credits not allowed by California: Certain deductions, such as Health Savings Account contributions or educator expenses, must be added back on the state return.
  
  
• Filing an amended or late return: If the Internal Revenue Service makes changes to your federal return or you discover errors, you must file a corrected California return using this form.
  
  
• Part-year or nonresident taxpayer using Form 540NR: California adjustments are still required to determine taxable income for California-sourced earnings accurately.
  
  
• Itemized deductions on your federal return: If federal and California itemized deductions differ, Part II of Schedule CA (540) must be completed.

Key Rules or Details for 2013

Several important rules apply to Schedule CA (540) (2013) that reflect differences in federal and California tax law.

• California excludes specific income types from taxation: Unemployment compensation, Social Security benefits, state income tax refunds, and interest from U.S. government obligations such as Treasury bonds are not considered taxable income under California law.
  
  
• California follows separate depreciation rules: Property placed in service before 1987 and certain assets under California’s notable credits must follow state-specific depreciation schedules, which can result in long-term basis differences.
  
  
• Certain federal deductions must be reversed for California purposes: For example, deductions such as tuition and fees, domestic production activities, and Health Savings Account contributions are not allowed in California and must be reported as additions.
  
  
• California applies different rules to itemized deductions: For instance, the medical deduction threshold is 7.5% of adjusted gross income in California, compared to 10% federally, which may lead to a higher deduction for California purposes.
  
  
• Special rules apply for military pay and spouse income: Under the Military Spouses Residency Relief Act and FTB Publication 1032, military wages and related adjustments may be excluded from California income depending on domicile and duty location.

Step-by-Step (High Level)

Follow these general steps to correctly complete Schedule CA (540) (2013) and file your California return:

• Start by completing your federal tax return: Use Form 1040, 1040A, or 1040EZ, and gather supporting documents such as W-2s, 1099s, and Schedule A if you itemize deductions.
  
  
• Fill out Part I for income adjustments: Transfer federal income amounts to Column A. Use Column B to subtract income that California does not tax, and Column C to add income that California includes but the federal government excludes.
  
  
• Adjust deductions and credits as needed: Remove any federal deductions not allowed by California, such as Health Savings Account contributions, and add any income California taxes but the federal government does not.
  
  
• Complete Part II if you itemize deductions: Start with your federal Schedule A totals, then adjust for California-specific rules such as the lower medical deduction threshold or disallowed private mortgage insurance.
  
  
• Transfer totals to Form 540 or Form 540NR: Report your California adjusted gross income and deductions by referencing the appropriate lines on your primary state income tax return.

Common Mistakes and How to Avoid Them

Taxpayers often overlook key differences between federal and California law, but these errors can be avoided by following clear practices:

• Forgetting to file Schedule CA (540): Always review whether any income or deductions differ between your federal and California returns; if they do, filing this separate tax form is mandatory.
  
  
• Entering incorrect values in Columns B or C: Enter all adjustments as positive numbers unless the instructions say otherwise to prevent miscalculations or understatements.
  
  
• Failing to maintain separate California basis records: Keep a running record of California-specific depreciation using Form FTB 3885A to report gains or losses when assets are sold correctly.
  
  
• Misapplying deduction thresholds or limits: Recalculate any limitations for itemized deductions based on your federal adjusted gross income, not your California adjusted gross income.
  
  
• Overlooking differences in pass-through entity reporting: Carefully compare the federal and California Schedule K-1s and enter any required adjustments on the appropriate lines of Schedule CA (540).
