Every answer below is written by the person who does that work. If your situation is more specific, book a free discovery call — that's what it's for.

Getting started

Less than you'd think. For the first conversation we want:

  • Your last two years of returns (federal and state)
  • Photo ID and Social Security numbers for everyone on the return
  • This year's income documents as they arrive — W-2s, 1099s, K-1s, brokerage statements
  • Business owners: a year-end profit & loss and balance sheet, or read-only access to your books
  • Landlords and investors: closing statements, rent rolls and a summary of expenses by property

Upload everything to the secure portal before we meet and the first hour is spent on planning, not paperwork. Our document checklist lists every form by situation.

Everything can be done remotely, and for most clients it is. Since 2020 every engagement runs through an encrypted client portal with e-signature and video planning sessions — we currently serve clients in 14 states, and the planning conversation is exactly the same over video as across the table.

If you'd rather meet in person, you're welcome at 210 Harbor Drive, Suite 400, downtown San Diego. Many clients come in once for onboarding and go virtual from there. Book either kind of meeting here.

Most individual returns are finished 7–10 business days after we have complete documents; business, trust and multi-entity returns take two to three weeks. Every return is reviewed by a second credentialed professional before it reaches you, and that review is never skipped to hit a date.

Documents that arrive in the last two weeks before a deadline are usually placed on extension so they get the same care — see the next question for why that costs you nothing.

  • March 15 — S-corporation and partnership returns (Forms 1120-S and 1065)
  • April 15 — individual (1040) and C-corporation returns, plus the first quarterly estimate
  • June 15, September 15, January 15 — remaining quarterly estimates
  • October 15 — extended individual deadline (September 15 for extended business returns)

An extension gives you six more months to file, not to pay. So we calculate what you'll owe, pay it with the extension, and there's no penalty and no interest. Extensions are free for clients and often produce a better return than a rushed April one. Full dates are on our deadline calendar.

A named CPA or Enrolled Agent from our team page prepares and signs your return. A second credentialed reviewer checks it line by line. Daniel Brooks' client-success team handles scheduling, documents and reminders, so your advisor's time goes to your plan.

You meet your advisor during onboarding and keep the same person year after year — no seasonal staff, no rotating call center.

Yes — 30 minutes, no card, no obligation. Bring last year's return and whatever's on your mind. You'll leave with two or three specific, dollar-ranked ideas whether or not you hire us, and if we're not the right fit we'll say so and point you somewhere better. Pick a time.
