AI is very good at helping founders write emails.
Sometimes a little too good.
You start with a simple question for your tax advisor. You give Claude or ChatGPT a few facts. Ten seconds later, Claude has thoughts.
A lot of thoughts.
There are possible tax treatments. Alternative interpretations. Risks. Caveats. Documentation considerations. Three paragraphs beginning with “It may also be worth considering…”
Suddenly, the question you wanted to ask is hiding somewhere around paragraph nine.
Your tax advisor does not need all of that.
They need the facts.
01Your advisor needs to know what actually happened
Most tax questions start with a fairly short list:
What happened?
How much was involved?
When did it happen?
Who paid whom?
Which company was involved?
Where are the people or companies located?
What are you planning to do next?
And, most importantly:
What are you asking us?
That information is usually far more useful than several paragraphs explaining what AI thinks the tax treatment might be.
You hired your tax advisor for that part.
02AI loves a blank space
If you leave out a fact, AI is very good at filling the gap.
That is useful when you are writing a birthday invitation.
It is less useful when you are discussing a shareholder transaction.
AI may quietly assume that a payment was a loan. Or compensation. Or a distribution. It may assume you are a U.S. tax resident, that the company has employees, that money moved in a certain order, or that an election was previously made.
Then it builds an impressive analysis on top of the assumption.
Your advisor now has a new job: figure out which parts of the email came from you and which parts came from Claude having another thought.
03A tax question does not need to sound like a tax memo
Suppose you took $637 from your company and have not repaid it yet.
You could send five paragraphs discussing shareholder loans, constructive distributions, documentation standards, repayment intent, possible reclassification, and the importance of contemporaneous records.
Or you could send:
“I took $637 from the company. I have not repaid it yet, but I intend to repay it before June 30. Can we leave it as a shareholder receivable? Do you need anything from me to document it?”
That is an excellent tax email.
It tells us what happened, what you intend to do, and what you want to know.
No memorandum required.
04More words can actually hide the important facts
Long AI-generated emails do not just take longer to read.
They can make the underlying issue harder to spot.
An important date may be buried in paragraph six. A change in ownership may appear after three paragraphs of AI analysis. The fact that money came from a foreign company rather than the founder personally may be mentioned almost as an aside.
Those details can completely change the tax answer.
The more noise surrounding them, the easier they are to miss.
That is the opposite of what good communication is supposed to accomplish.
05Yes, it can also cost you more
Someone still has to read the whole email.
If your advisor bills hourly, reviewing and untangling a long AI-generated message can turn a quick question into billable advisory time.
And even if your current tax package includes routine emails and calls, the cost does not magically disappear.
Firms pay attention to how much time accounts require.
If a client routinely turns simple questions into lengthy research exercises, that can become part of the conversation when the engagement is repriced or renewed.
You do not need to write like a tax professional to save money.
Quite the opposite.
Clear facts are cheap to review. Noise is expensive.
06Give AI a better job
AI is still extremely useful for communicating with your tax advisor.
Use it to organize a messy timeline.
Ask it to summarize a long explanation.
Have it pull out dates, dollar amounts, entities, and open questions.
Ask it to identify information you may have forgotten to include.
And, perhaps most importantly, ask it to make your email shorter.
A good prompt is:
“Rewrite this for my tax advisor. Keep only confirmed facts. Clearly identify anything I am unsure about. End with the specific question I need answered. Do not provide tax analysis or introduce additional tax issues.”
That is a very different assignment from:
“Analyze all potential tax consequences.”
The second prompt is how you end up with Claude's complete thoughts on the economic substance doctrine when you were trying to ask about a $200 software charge.
07Teach your AI how you want to communicate
If you use AI regularly for work, consider adding standing instructions for emails to your tax, legal, and accounting advisors.
Something like:
For emails to my professional advisors:
- Lead with the question or action I need from them.
- Keep the email concise unless the facts genuinely require more detail.
- Separate confirmed facts from assumptions or things I am unsure about.
- Do not provide tax or legal analysis unless I specifically request it.
- Do not invent additional risks, elections, issues, or alternative treatments merely to be comprehensive.
- Include relevant dates, dollar amounts, entities, countries, and transaction details.
- If I give you a long explanation, summarize it instead of expanding it.
- Before finalizing, remove anything that does not help the advisor understand the facts or answer my question.
You can still ask AI to research the issue separately.
Just do not automatically forward the entire research project to your advisor.
08One useful test before you hit Send
Read your email once and ask:
Can my advisor tell within 30 seconds what happened and what I am asking?
If yes, send it.
If the actual question does not appear until the bottom of the screen, Claude probably had too much fun.
Ask it to shorten the email again.
Your tax advisor will thank you.
Your invoice might too.
