5 Tax‑Planning Mistakes Advisors Make When On‑boarding New Clients

On‑boarding sets the tone for the entire client relationship. Get tax planning right in those first weeks, and clients will see you as their long‑term partner. Miss key steps, and you’ll spend years trying to catch up. Here are five common tax‑related mistakes to avoid.

  1. Not requiring a recent tax return.
    Without it, you’re guessing. Make the return a standard part of your data‑gathering process and explain why it matters.
  2. Failing to ask about prior planning.
    Many clients have done Roth conversions, stock option exercises, or business restructures without fully understanding them. If you don’t ask, you won’t know what you’re building on.
  3. Ignoring entity structure for business owners.
    Whether a client is a sole proprietor, S corporation, or partnership has major tax implications. Treating all business owners the same is a missed opportunity.
  4. Overlooking carryforwards and “leftover” tax attributes.
    Capital loss carryforwards, unused charitable deductions, and other attributes can shape the next few years of planning but only if you look for them.
  5. Not identifying one or two quick‑win opportunities.
    New clients want to see early value. If you can highlight even a simple improvement like correcting withholding, adjusting contributions, or planning a smarter giving strategy you build trust fast.
