How to offer tax advisory services: a step-by-step guide for firms

By Jonathan Solomon, Founder of LucaLedger. Last updated June 2026.

"In seven years working with accounting firms, the ones that grew weren't doing more returns, they were turning compliance clients into advisory clients. The return gets you in the door; the planning is the business. Most firms are sitting on an advisory practice inside their existing client list and don't realize it."

What "tax advisory" actually means

Tax preparation is compliance: you report what already happened and file the return. Tax advisory , tax planning, is the opposite direction in time: you look forward and change the outcome, finding and quantifying strategies that lower a future tax bill before it's owed. (We define the distinction in detail in tax planning vs tax prep software.)

That difference is the whole opportunity. Compliance is a commodity, price-shopped, deadline-bound, and capped at one return per client per year. Advisory is a relationship: higher-margin, year-round, and valued on results instead of forms. The firms pulling away from the pack aren't preparing more returns; they're converting the returns they already do into advisory engagements.

Here's how to build that, step by step.

Step 1, Define the offer

Before you sell anything, decide what you're actually selling. "Tax planning" is vague; a client buys something specific. A real advisory offer is a proactive analysis that surfaces named strategies and quantifies the dollar savings of each, for example: entity choice (S-corp election), retirement-vehicle selection, accountable plans, depreciation and §179/bonus elections, income and expense timing, QBI optimization, hiring family members, or real-estate strategies.

Two decisions make the offer concrete:

• Scope. Is this a one-time plan, an annual plan, or an ongoing advisory relationship with quarterly check-ins? Most firms start with a one-time plan and graduate clients to a retainer.
• Niche. You don't have to niche, but it helps enormously. "Tax planning for dentists" or "for real-estate investors" makes you the obvious expert, makes the strategies repeatable, and makes pricing easier because the value is legible. Pick the niche where your existing book is heaviest.

Step 2, Start with the clients you already have

The most common mistake is treating advisory as a new-business problem, building a funnel to find strangers. You don't need to. Your warm market is your current compliance book. Those clients already trust you, and you already hold their data, which is most of the work.

Sort your client list and flag the ones with the most to gain: business owners, higher-income households, anyone with K-1s, real estate, or a recent liquidity event. A W-2-only client with a standard deduction has little to plan; a profitable S-corp owner has a lot. Start the conversations there. Converting even a fraction of your existing book is usually a bigger revenue change than any marketing campaign.

Step 3, Price it on value, not hours

This is where most firms leave money on the table. Billing advisory hourly anchors it to your time, which is the wrong unit, clients don't care how long the analysis took; they care what it saves them.

Three common models:

• Fixed planning fee, a one-time price for the analysis and the written plan. Simple, easy to say yes to, and the most common starting point.
• Ongoing advisory retainer, a monthly or quarterly fee for continuous planning and access. Higher lifetime value; the goal to graduate clients toward.
• Percentage-of-savings, priced as a share of the tax saved. It aligns incentives but carries professional and practical complications; use it carefully and know your jurisdiction's rules.

Whatever the model, anchor to the value you find. If a plan surfaces $40,000 in legitimate savings, a $3,000 to $7,000 fee is easy arithmetic for the client. The deliverable in Step 4 is what makes that math visible.

Step 4, Build the deliverable

The product a client pays for is a written plan, not a conversation. A good plan has four parts: the client's current situation, the recommended strategies, the quantified dollar savings of each, and, this is what separates credible planning from guesswork, the authority behind each strategy (the relevant Internal Revenue Code section, regulation, or ruling).

Make it firm-branded and clear enough that the client can understand the recommendation and say yes without a tax degree. Authority-grounding does double duty: it builds the client's trust and it protects you, because every recommendation traces to a source. Generic "AI told me" suggestions don't survive scrutiny; cited strategies do.

Step 5, Sell it to your clients

The conversation is simpler than firms fear. It usually sounds like: "Right now, I file what already happened. I'd like to show you what we could change going forward." Then lead with one concrete finding, a single strategy and its savings, and let the plan close the rest.

Two things make this work: you're talking to people who already trust you, and you're showing them money, not selling them a service. The firms that struggle are usually the ones who pitch "advisory" as an abstraction instead of opening with a specific, quantified result.

Step 6, Deliver and systematize

A one-off plan is a project; a repeatable plan is a practice. To scale advisory without it eating your year, standardize three things: a process (the steps from data to delivered plan), a template (so every plan looks professional and consistent), and software that builds the plan from the books so you're not starting from a blank page each time. Systematizing is what turns "I did some planning for a client" into a real, sellable advisory line with predictable margins.

What's hard about this (the honest version)

Advisory isn't free money, and a guide that pretended otherwise would be useless. Go in clear-eyed about the friction:

• It requires real tax competence. You're recommending strategies clients will act on. Get them right, stay current, and know the limits of your own expertise.
• Pricing pushback is real at first. You're changing how clients value you, from a form-filer to an advisor. The first few conversations are the hardest; it gets easier once you have results to point to.
• Not every client is a fit. Simple situations have little to plan. Don't force advisory onto a client who doesn't need it, it erodes trust.
• It eats time without a process. The firms that burn out on advisory are the ones doing every plan from scratch. Step 6 isn't optional.

On credentials: tax planning and advisory are offered by CPAs, EAs, and other qualified tax professionals, but the right scope depends on your credentials, your state's rules, and the specific service. Be explicit about what you're qualified to advise on, and know when to bring in a CPA or attorney. (This article is general practice-building guidance, not legal or tax advice.)

Where LucaLedger fits

Advisory is only as good as the data under it. LucaLedger's tax planning runs on the books and return you already keep in the platform and ties each strategy to the Internal Revenue Code, so the plan you charge for is grounded in the client's real numbers, not a re-keyed snapshot, and the deliverable assembles itself instead of starting from blank. For how it compares to dedicated planning tools, see LucaLedger vs Corvee.
