AI for tax and accounting: what it can really do

In short

Italy has an advantage: with mandatory e-invoicing documents are already structured data, perfect for AI.
AI is excellent at reading, classifying, comparing, searching and drafting. Not at deciding tax treatment or signing.
Chatbots’ tax answers “from memory” are the riskiest part: rules and thresholds change every year.
A professional using AI must tell the client (Italian Law 132/2025, Art. 13) and remains responsible for everything.

This guide describes uses of AI in accounting and tax work. It is not tax advice: for your case, consult a qualified professional.

Why accounting is fertile ground

Accounting work has three features AI likes: lots of documents, repeated rules, verifiable results (accounts must balance). In Italy, business invoices go through the Revenue Agency’s exchange system in XML format: supplier, VAT number, net amount, rates and type of transaction are already structured fields. A model can read, check and propose the entry far more reliably than from a scanned PDF.

Where AI saves hours

1. Supplier invoices and bookkeeping

Reading invoices, proposing the cost account and VAT treatment based on the client’s history, flagging anomalies (new supplier, unusual rate, out-of-range amount). A person approves or corrects: corrections become examples for next time.

2. Bank reconciliations

Matching statement lines with invoices, even when the reference is badly written or one transfer pays several invoices. AI proposes, a person confirms doubtful cases.

3. Consistency checks

Comparing financial statements and tax returns, checking totals across reports, finding year-on-year variances to explain. Boring, valuable work: AI does it in minutes.

4. Regulatory and practice research

Finding the relevant law, circular or ruling, with links. Always verified against the official text (see the hallucinations guide: legal references are among the things models invent most easily).

5. Client communications

Drafts of client memos, deadline reminders, emails explaining an obligation in plain words. The professional rereads, corrects and signs.

6. Analysis for the client

From the accounting export: revenue and cost trends, margins by client or product, collection times, simple cash forecasts. With code execution (see the documents and Excel guide), the maths is exact.

Where a professional is always needed

Classifying transactions: is a cost deductible? is a transaction VAT-exempt or out of scope? is a fee self-employment income or other income? These are judgements, not data extraction.
Planning and choices: tax regime, company form, extraordinary transactions.
Dealing with the authorities: audits, disputes, litigation.
Signature and responsibility: the tax return, the financial statements, compliance certifications.

The chatbot is not your accountant

Asking a generic chatbot “how much tax will I pay if…” is risky: thresholds, rates and rules change every year, and the model may quote the old version with full confidence. Use it to understand concepts and prepare the right questions, then check with a professional.

Rules for firms using AI

Client notice: Italian Law 132/2025 (Art. 13) requires professionals to clearly state which AI systems they use; for Italian chartered accountants, code of ethics rules also apply from 21 November 2025.
AI only as support: the professional’s intellectual work must prevail.
Client data: only on business plans that don’t train models, with a data-processing agreement and minimum necessary data (see the privacy and security guide).
Professional secrecy: no client documents on free personal accounts.

Two useful prompts for a firm

Explaining an obligation to a client

You are an accountant writing to a client with no tax knowledge. In max 150 words explain what [obligation] is, why they must do it, by when and what they need to send me. Friendly tone, no unexplained jargon. Don’t state amounts or rates: I’ll add them after checking.

Consistency check on an export

Attached are the 2025 and 2024 accounting exports for the same client. Run code to: compare totals by account, highlight variances above 20% and above €1,000, list new or vanished accounts, and suppliers with amounts very different from last year. Give no tax interpretation: just list the anomalies to check, with the numbers.

For freelancers

Even without being an accountant, AI helps you: keep invoices and receipts in order (photo → table), understand deadlines, prepare questions for your advisor, analyse how your business is doing. The rule stays the same: AI organises and explains, the professional decides.

My work

It’s the method I always recommend: AI drafts, a qualified person checks and signs. If you want to bring these flows into your finance team or firm, you’ll find my AI consulting on the About page.
