What California Form 540 (2010) Is For
California Form 540 is the California Resident Income Tax Return for full-year residents filing 2010 tax returns. It reports income, deductions, and tax credits, and it calculates taxable income and tax liability. The return starts from federal adjusted gross income from Form 1040, Form 1040A, or Form 1040EZ.
California law requires residents to report worldwide income under the California Revenue and Taxation Code and starting figures under the Internal Revenue Code. Taxpayers complete Schedule CA (540) for California adjustments, including Net Operating Loss limits, NOL suspension rules, and carryover period tracking.
The General Information section explains Form 540 2EZ eligibility for the taxable year, and references Form FTB 3805Q and Form FTB 3805V.
When You’d Use California Form 540 (2010)
A taxpayer uses Form 540 for the 2010 tax year when California residency lasted the entire taxable year. A part-year resident or nonresident files Form 540NR, the California Nonresident or Part-Year Resident Income Tax Return.
Some taxpayers file Form 540 2EZ when filing status and income requirements match the form instructions. Deadlines follow state and federal law timing rules, including extensions that cover filing, not payment.
Taxpayers should keep W-2 forms and 1099 forms to support withholding and payments. A filer who identifies an error files the applicable amended return after the original filing.
Key Rules or Details for 2010
Form 540 follows concepts from the Internal Revenue Code, and California law differs in many areas. Schedule CA (540) reconciles federal adjusted gross income to California taxable income with additions and subtractions.
Personal exemptions, standard deductions, and nonrefundable tax credits can reduce tax liability on 2010 tax returns. A filer should track California adjustments connected to Net Operating Loss rules, including NOL suspension and carryover period limits.
Some limited liability companies file Form 568, Limited Liability Company Return of Income, under separate filing rules. Certain forms, including Form 3514 for the California Earned Income Tax Credit, apply only when eligibility exists.
Step-by-Step (High Level)
Step 1: Taxpayers gather income statements, W-2 forms, 1099 forms, and payment records for the taxable year.
Step 2: Taxpayers complete Form 1040, Form 1040A, or Form 1040EZ, and taxpayers confirm federal adjusted gross income amounts.
Step 3: Filers prepare Schedule CA (540) under the California Revenue and Taxation Code, and filers document Net Operating Loss, carryover period, and NOL suspension.
Step 4: The return preparer selects deductions, claims personal exemptions and tax credits, and checks Form FTB 3805V for carryovers.
Step 5: The taxpayer reviews Form 540 2EZ eligibility in General Information, confirms the 540EZ form selection, and signs, files, and retains copies.
Common Mistakes and How to Avoid Them
Processing delays often result from repeatable documentation errors in submitted returns. Clear correction steps support accurate processing and proper record matching.
- Wrong Residency Return Selected: This mistake occurs when a filer submits Form 540 despite part-year residency. The taxpayer must file Form 540NR and report income by residency period and California-sourced income rules.
- Withholding Taken From Federal Boxes: This mistake occurs when a filer enters federal withholding instead of state wages withholding totals. The taxpayer must total California withholding from Box 17 on all W-2 forms and relevant 1099 forms.
- Schedule CA (540) Missing: This mistake occurs when a filer omits Schedule CA (540) while reporting California adjustments from federal adjusted gross income. The taxpayer must attach Schedule CA (540) and complete all required adjustment lines accurately.
- Incorrect Filing Status Used: This mistake occurs when a filer selects a filing status that does not match the federal return filing status. The taxpayer must match the Form 1040 filing status unless an identified California exception applies.
- Missing Required Signatures: This mistake occurs when a filer submits a paper return without the required signatures and dates. The taxpayer must sign and date the return, and the spouse must also sign joint returns.
What Happens After You File
The Franchise Tax Board reviews Form 540 for math accuracy, Social Security number accuracy, ZIP code accuracy, and missing schedules. The agency matches withholding data and California-sourced income information against reported W-2 forms and 1099 forms. Staff members issue notices when Schedule CA (540NR) entries, payments, or reported figures do not align with Franchise Tax Board records.
Refund processing can include offsets for certain state obligations, and the agency issues a notice describing the adjustment. Taxpayers should retain records for the standard limitation period, including any Disaster Loss documentation on Form 4684. A filer claiming an IRC Section 165(i) election should keep the Declared Disasters list and the Disaster Loss Code.
