Step-by-Step Guide for Advisors to Answer Clients’ “What Is My AGI” Questions

As a financial advisor, clients often come to you asking “what is my AGI?” Adjusted Gross Income is a key figure that affects:

• Retirement contribution limits for IRAs and HSAs
  
  

• Eligibility for tax credits like the EITC or Child Tax Credit
  
  

• Phase-outs for deductions and Roth conversions
  
  

• Overall tax planning and strategy
  
  

Having a clear process to determine AGI ensures you provide accurate, actionable advice.

Step 1: Gather Client Tax Documents

The first step is to collect all relevant documents from the client:

• Prior-year Form 1040 (or 1040-SR)
  
  

• Supporting schedules (Schedule 1–3, if applicable)
  
  

• W-2s and 1099s for all income sources
  
  

• Any adjustments, such as student loan interest, IRA contributions, or business expenses
  
  

Comprehensive documentation helps capture all income and adjustments necessary to calculate AGI.

Step 2: Locate AGI on Form 1040

AGI is typically reported on Form 1040:

• For the most recent tax returns, AGI is on Line 11
  
  

• For older forms, it may appear on a different line; verify based on the year
  
  

• If a return was amended, check Form 1040-X to confirm the updated AGI
  
  

This line provides the total income minus allowable adjustments, forming the foundation for tax planning.

Step 3: Use IRS Transcripts if Returns Are Unavailable

Clients may not always have their previous returns. In such cases, you can obtain the AGI from the IRS:

• Tax Return Transcript: Shows line-by-line AGI and income
  
  

• Account Transcript: Confirms payments, refunds, and balances
  
  

• Wage and Income Transcript: Verifies all reported W-2s, 1099s, and other income
  
  

Request transcripts via Form 4506-T with client authorization. Transcripts are generally available for the past 10 years.

Step 4: Verify All Income Streams Are Included

For clients with multiple sources of income, ensure that AGI reflects:

• Wages from all employers
  
  

• Self-employment or freelance income
  
  

• Investment income (interest, dividends, capital gains)
  
  

• Adjustments such as contributions to traditional IRAs, student loan interest, or educator expenses
  
  

Accurate verification prevents mistakes in retirement planning and credit eligibility.

Step 5: Apply AGI to Client Planning

Once AGI is determined, use it to guide key financial and tax strategies:

• IRA Contributions: Ensure eligibility based on AGI limits
  
  

• Roth Conversions: Plan conversions without exceeding phase-out thresholds
  
  

• Credits and Deductions: Determine eligibility for EITC, Child Tax Credit, and charitable deductions
  
  

• Tax Planning: Evaluate impact of income fluctuations and optimize strategies
  
  

AGI is a central figure that informs many aspects of proactive financial advice.

Common Mistakes Advisors Should Avoid

Even experienced advisors can misstep when calculating AGI:

• Using incomplete or outdated tax returns
  
  

• Overlooking amendments that adjust AGI
  
  

• Ignoring certain income sources, like freelance work or investments
  
  

• Failing to verify transcripts when client documents are missing
  
  

Avoiding these mistakes ensures accurate guidance and compliance.
