Is AI in accounting reliable? The 20+ points a human checks

In short. Not quite. AI is reliable for repetitive and structured tasks (data entry, reconciliation, anomaly detection), but not for judgment, tax strategy, or compliance. A verified human must validate the result and be legally accountable for it. Reliability comes from this dual layer, not from the algorithm alone.

We sold you software that "does your accounting with AI." The real question isn't whether the tool is impressive (it is), but whether it's reliable enough to let it generate your financial statements and tax returns without human oversight. The honest answer: it depends on the task. This is where AI delivers, where it falls short, and where the specific details are those that a vetted accountant checks but a chatbot never will.

Bankeo has no stake in this response. We don't sell AI software or accounting services. We simply connect entrepreneurs with vetted accountants from our network, free of charge. This is what makes us the only truly neutral third party in this debate: we don't advocate for any particular software publisher or firm; we connect you with a human expert who can provide validation.

What does AI already do well in accounting?

Let's be clear: AI in accounting isn't magic, but it's not just hot air either. For repetitive and well-defined tasks, it's fast, available 24/7, and often more consistent than manual data entry. Specifically, it excels at:

• capture and categorize invoices and statements from a photo or file;
• perform bank reconciliation by matching transactions and entries;
• detect anomalies (an unusual amount, a duplicate, a misclassified expense);
• produce a first draft of a report or email;
• perform a first-level search on a general rule.

In this area, rejecting AI on principle would be a mistake. An accountant who uses it correctly costs you less in data entry time and can focus on what matters. AI enhances accounting. The problem begins when we believe it replaces it.

What can't AI do in accounting?

AI processes what it has already seen. It doesn't understand your context, it has no responsibility, and it boldly invents things when it doesn't know. The following remain beyond its reach:

• judgment in an ambiguous case (a mixed personal/business expense, an unusual transaction);
• tax strategy , that is, optimizing legally according to your situation, not the average;
• legal responsibility : signing a declaration and assuming professional responsibility;
• to represent you before the tax authorities; Canada (CRA) or Revenu Québec in case of audit;
• the relationship and support over time;
• to catch up with her own hallucinations , because she doesn't know she made a mistake.

This is also the line drawn by professional orders. According to the Ordre des CPA du Québec , AI can automate some administrative work, but professional judgment, the interpretation of complex situations, and the relationship of trust remain the responsibility of the professional, who remains liable for any errors, not the algorithm. CPA Ontario takes the same approach: the responsibility of the professional using AI is non-transferable . In other words, a chatbot will never sign anything on your behalf, and no one will sue it if it makes a mistake.

Where does AI go wrong? A concrete example

Take a business meal expense. The AI ​​sees "restaurant," classifies the bill as a meal expense, and applies the deduction. Except that at Canada Meal and entertainment expenses are generally 50% deductible, with exceptions depending on the context (e.g., events for all staff, meals included in a package, specific industry). An AI that applies the general rule to an exception will cause you to claim the wrong amount. Multiply this by hundreds of transactions throughout the year, and the error becomes a real risk of tax reassessment.

The trap isn't that AI makes a mistake once. It's that it makes mistakes confidently , without raising any red flags. A verified human, on the other hand, knows where to look twice . That's the crucial difference between a tool and a professional who is accountable for their work.

AI or human accountant? The real answer

This is a false dichotomy. The right combination isn't "one or the other," it's AI for speed, and humans for judgment and accountability . CPA Canada puts it well: the Code of Ethics remains the lens through which we view AI. Similarly, IFAC reiterates that the IESBA Code of Ethics fully applies to the use of AI by professionals: the tool does not exempt them from any ethical obligations. A chatbot has none of these duties. A vetted accountant does.

The relevant question, therefore, is not "Is AI reliable?" but "Who validates the AI's output and who is accountable for it?" Without an answer to this, the claimed reliability of a software program is worth very little.

Les 20+ points qu'un humain vérifie (et pas un chatbot)

Chez Bankeo, cette couche de validation humaine a un nom : l'Indice Bankeo, notre grille de plus de 20 critères de vérification, alignée sur l'esprit des guides des ordres professionnels (jugement, imputabilité, éthique). Voici une dizaine de ces points, pour rendre concret ce qu'un humain contrôle :

1. Does the deduction applied correspond to your situation, not to the average rule?
2. Is the deductibility rate (50% for meals, pro rata vehicle usage) correct?
3. Is the distinction between personal and professional expenses valid?
4. Is the structure (self-employed, incorporated) still optimal this year?
5. Are the provisional payments correctly calculated to avoid interest?
6. Is GST/QST being applied, claimed and remitted correctly?
7. Is the payroll processing and withholding tax collection compliant?
8. Are the CRA and Revenu Québec deadlines covered, without any oversights?
9. Was an unusual transaction analyzed rather than categorized by default?
10. In the event of an audit, can someone represent you and defend the figures?

Un chatbot peut vous donner une réponse plausible sur chacun. Aucun ne répond de cette réponse devant l'ARC. La grille complète de plus de 20 critères est là pour ça : voir l'Indice Bankeo.

How much does an AI error cost on your taxes?

« Gratuit avec l'IA » cache un coût. Une erreur sur une déclaration, c'est des intérêts, des pénalités, du temps perdu à corriger, et parfois un redressement. À côté, le vrai prix d'un comptable est connu : selon le Baromètre Bankeo, la médiane des honoraires tourne autour de 3 000 $ par an, dans une fourchette de 500 $ à 6 000 $ selon le secteur. Ce n'est pas une dépense contre l'IA, c'est la couche qui rend l'IA fiable : quelqu'un valide et assume.

What AI does, what a human does (verified)

• AI: Applies the average rule based on what it has already seen. A verified human: Adapts the rule to your real-world context.
• AI: Fast and available 24/7 for repetitive tasks. A verified human: Takes the time to assess ambiguous cases.
• AI: Signs nothing, assumes no responsibility. A verified human: Signs and is accountable for their work before the Order.
• AI: Not available for verification. A verified human: Represents you before the CRA and Revenu Québec.
• AI: Confidently invents when it doesn't know. A verified human: Identifies the error and knows where to double-check.
• AI: Optimizes based on averages, without its own strategy. A verified human: Optimizes legally according to your actual situation.
• AI: No year-to-year tracking. A verified human: Knows your file and adjusts over time.
• L'IA : « Gratuit » affiché, coût caché en cas d'erreur. Un humain vérifié : Coût connu d'avance (Baromètre : médiane ~3 000 $/an).

Frequently asked questions

Can AI completely replace my accountant?

No. AI replaces tasks (data entry, reconciliation, categorization), not the accountant. According to the Ordre des CPA du Québec, professional judgment and the relationship of trust remain the responsibility of the professional, who is accountable for errors, not the algorithm. The right combination is AI for speed and a verified human for validation.

Is it risky to file my taxes using only AI?

Yes, if no one validates it. The AI ​​applies the average rule and can make a mistake on an exception (deduction rate, mixed expense, advance payments) without raising any red flags. An error results in interest, penalties, and sometimes an adjustment. A verified human checks and accepts the result.

Specifically, what does a human check that AI does not check?

Que la déduction correspond à votre situation réelle, que la structure d'entreprise reste optimale, que la TPS/TVQ et la paie sont conformes, que rien n'est oublié aux échéances, et qu'en cas de vérification quelqu'un peut vous représenter. Bankeo en a fait une grille de plus de 20 critères : l'Indice Bankeo.

If I already use AI software, do I still need an accountant?

Keep your tool for speed; it does repetitive tasks very well. Add the missing layer: a human who validates the result and is legally accountable for it. It's this dual layer that makes the whole system reliable, not AI alone.

How much does this human validation cost?

Le jumelage par Bankeo est gratuit pour l'entrepreneur, vous ne payez jamais Bankeo. Pour le comptable lui-même, le Baromètre Bankeo situe la médiane des honoraires autour de 3 000 $ par an, dans une fourchette de 500 $ à 6 000 $ selon le secteur. Un coût connu d'avance, contre le coût caché d'une erreur non détectée.
