For Tax Managers ·
What you'll accomplish
By the end of this guide, you'll use ChatGPT to quickly generate tax planning scenario comparisons — entity structure decisions, retirement contribution strategies, capital gains timing, and more. What once required 60–90 minutes of analysis and formatting becomes a 15-minute verify-and-customize task.
What you'll need
Before going to ChatGPT, know exactly what you're comparing:
Go to chat.openai.com. Start a new conversation. Set context first so all comparisons in this session are relevant:
"I'm a Tax Manager at a CPA firm advising clients on tax planning. I'll describe client situations and planning options, and you'll help me compare the tax implications of each option. Show me estimated tax impacts where possible and flag any assumptions you're making. I'll verify all calculations against my tax software before presenting to the client."
Describe the client situation and the options to compare. The more specific, the better.
Good formats:
What you should see: A structured comparison with estimated tax impacts, pros and cons for each option, and a recommended approach given the client's situation.
ChatGPT's tax calculations are approximations — useful for directional analysis and client conversations, not for final planning advice. Always:
Troubleshooting: If the calculations seem off, ask: "Show your calculation step by step." This reveals where the AI is making assumptions — you can then correct it.
After verifying the comparison, ask: "Write a 3-paragraph client-ready summary of these three options that I can include in a planning memo. Plain language, no tax jargon, focus on the after-tax outcomes and what the client needs to decide."
Roth conversion analysis:
Compare Roth conversion vs. no conversion for a client: [key facts including current bracket, projected retirement bracket, years to retirement, amount to convert]. Show: additional tax cost this year, estimated future tax savings, break-even timeline. Recommend whether conversion makes sense given their facts.
Capital gains timing:
Client will realize $300,000 in long-term capital gains from a business sale. Compare: recognizing all gains this year vs. installment sale over 3 years vs. Qualified Opportunity Zone investment of the gain. Client facts: [income level, other investment income, state]. Show approximate tax impact and after-tax proceeds for each option.
Business entity comparison:
New client starting a business with 2 partners, projecting $400,000 net income year 1. Compare: LLC taxed as partnership, S-corp, and C-corp. Show estimated total tax burden for each structure (entity + owner level), major pros and cons, and recommended structure. Client goals: minimize current tax, keep structure flexible for possible outside investors in 2–3 years.
