Why your accountant doesn't solve tax problems

There’s a sentence that comes up in almost every first meeting with a business owner who arrives at VMAHUB with a tax problem: “My accountant said this isn’t their job.”

The frustration is genuine. The owner pays a monthly fee, does everything right on their end, and when a problem appears — a tax foreclosure, an infraction notice, a lost credit — the accountant vanishes. It isn’t necessarily negligence. In most cases, it’s the wrong specialization.

Vivian Sampaio, founding partner of VMAHUB and a tax attorney with more than 26 years of experience, explains the difference between basic accounting and tax advisory — and why so many people pay an accountant expecting a consultant.

The difference between an accountant and a tax consultant

What each professional does

The accountant calculates taxes, generates payment slips, organizes trial balances, runs payroll, fulfills ancillary obligations, and closes the books. They may hold an accounting credential (CRC) and, at best, a specialization in tax. But the focus of their work is to execute the accounting routine.

The tax consultant works before and after the accounting routine. Before: they plan the tax regime, corporate structure, and operations. After: they defend you in audits, recover credits, contest infraction notices, and conduct installment plans. They are frequently a tax attorney, or an accountant with a graduate degree and practice in tax law.

The confusion arises because many accounting firms sell “tax advisory” as an add-on to the contract — but, in practice, they only do execution. When a real problem hits, they don’t have the structure or competence to resolve it.

Why most accountants don’t act as consultants

Acting as a tax consultant requires two pillars: deep tax-law knowledge (the Constitution, the National Tax Code, complementary laws, up-to-date case law) and availability for one-off projects (defenses, opinions, planning). Accounting firms earn by volume — serving many clients in the monthly routine. The economic model doesn’t allow time for long projects with each client.

That’s why accountants normally outsource complex tax matters to partner attorneys. When yours doesn’t have a structured partnership, you’re left unassisted.

Signs that you need a tax consultant

Active tax foreclosure

If the Revenue Service or the Attorney General’s office has already registered your company in the active debt roster and the case is in foreclosure, it’s a job for a consultant. An accountant may negotiate a simple installment plan, but defending you through foreclosure objections, lifting a lien, or negotiating a tax settlement requires a tax attorney.

Recurring infraction notices

Received an infraction notice? You have 30 days to challenge it. A well-built defense overturns or reduces the notice. Accountants tend to file a “standard” challenge — copy-paste that loses at first instance. A specialized defense has a real chance of success.

Unused tax credits

Did your company pay PIS/COFINS under the cumulative regime when it could have used the non-cumulative one? You have the right to recover up to 5 years back. Do you have ISS, INSS, or IR withholdings at source that were never deducted? These credits can add up to significant amounts — but they are only recoverable with a technical assessment and a formal request. Accountants rarely do this recovery work.

Corporate restructuring

Are you going to open a branch, create a holding company, separate activities, or merge companies? Each of these moves has a relevant tax impact (ITBI, ITCMD, IRPJ, CSLL, ISS, PIS/COFINS). Without a consultant, the design ends up improvised and the bill comes later.

Litigation with a partner or heir

A shareholder dispute has immediate tax implications (ITCMD on transfer by succession, IRPF on capital gains when a partner withdraws, partial dissolution). Here, the tax consultant works alongside a corporate-law attorney.

What a good tax consultant does that an accountant doesn’t

The practical difference goes beyond the formal competencies:

Proactive tax planning: reviews the regime annually, simulates scenarios, and proposes migration when advantageous
Preventive tax audit: reviews the last 5 years to identify liabilities and opportunities
Credit recovery: assesses non-cumulative PIS/COFINS, withheld ISS, INSS on assignment, IR withheld at source
Administrative defense: technical challenge to an infraction notice, statement of disagreement in offset disputes
Judicial defense: foreclosure objections, writ of mandamus, declaratory actions
Tax opinions: prior assessment of a complex operation to provide legal certainty
Tax compliance: analysis of new operations from a tax standpoint before implementing them

How VMAHUB can help

VMAHUB operates with a hybrid model: routine accounting + specialized tax advisory under the same roof. This eliminates the classic problem of an owner who has to coordinate two professionals (an accountant and an attorney) who don’t know each other.

For companies with active tax problems — tax foreclosure, infraction notice, lost credit — we conduct an initial audit and propose a concrete action plan, with deadlines and a realistic expectation of results.

When it’s worth changing accountants to solve this

If your current accountant:

Has never proposed a proactive review of your tax regime
Doesn’t conduct a defense against an infraction notice (or charges separately for it without having a partner attorney)
Hasn’t assessed credits to be recovered
Hasn’t warned you about the 2026 tax reform

It may be time to consider switching to a model that delivers advisory work, not just execution. Read Signs that you need to change accountants and What to ask before hiring a new accountant.

What it costs not to have a tax consultant

The cost of lacking tax advisory rarely shows up on a single invoice. It shows up spread out:

Overpaid tax from an inadequate regime, over months or years without review.
Time-barred credits — non-cumulative PIS/COFINS, withheld ISS, and IR at source have a 5-year window for refund. After that, the credit disappears.
Fines and interest on infraction notices that, with a qualified defense, would have been reduced or overturned.
Labor liabilities stemming from poorly structured outsourcing that a consultant would have detected beforehand.

In most cases, tax advisory pays for itself within the first year — through the savings identified and the liabilities prevented. Companies that calculate the ROI of advisory rarely go back to operating without it.
