Tax return review: every return recalculated before you sign
Your accountants prepare and file the returns. The agent recalculates them with your own data and tells you what does not add up before you sign.
The problem
“The return arrives on the last day and I sign it because I have no choice.” Whoever signs answers for what they sign. But checking a tax return means having the quarter's invoices, payslips and bank transactions in front of you, and nobody has that afternoon.
It happens to managing directors and finance directors in any company whose taxes are in the hands of an outside firm. The firm does good work, but it works with what it receives: an invoice booked in another period or a missing expense is something it cannot see.
How it is done today
The return arrives by email close to the deadline. Someone opens it, looks at the result, compares it from memory with last quarter's and gives the go-ahead. If the figure is a surprise, they ask the accountants and wait for the answer with the deadline looming.
Really checking it, box by box, is a weekend's work. That is why it hardly ever gets done.
How we solve it
- It finds in your mailbox the returns your accountants have sent for the period and reads from each one the boxes, the result, the payment method, the account to be charged and the date.
- It recalculates each return with your data: sales and their tax, from issued invoices; input tax and withholdings on professionals, from received ones; payroll withholdings, from the payslips; and payments already made, from the bank transactions.
- It compares box by box. For each difference it gives the likely cause: an invoice from another period, a non-deductible expense, rounding. If it cannot find one, it says so.
- It checks that the returns are consistent with each other, for instance that the intra-EU transactions on form 303 match those on form 349.
- It gives a verdict per return: it adds up, it adds up with doubts, it does not add up, or alert. A deferral or instalment plan nobody asked for is an alert: it stops and tells you.
- It prepares the questions for your accountants. Before you get them, a second agent tries to knock each one down: if the answer was already in your data, if the mistake is the agent's own or if the figures are not exact, the question is rewritten or dropped.
- It hands you the summary: the verdict on each return, how much will be charged, on what day and to which account. After the charge it checks that what was collected matches what was reviewed.

10tax forms checked before signing
In our own company, no return is signed without being recalculated first. The checks, the bank reconciliation and the quarter's accounting close used to take a whole weekend; now they take an hour.
What it takes
Timeline
The tax calendar sets it: the sensible thing is to have it ready before a quarter ends and review that close with real data. How long it takes to get there depends on the state of your invoices today; we look at it in the assessment.
Data and access
Read access to the mailbox your accountants write to, to issued and received invoices, to the payslips and to the bank transactions. All read-only. And the list of returns your company files.
Your tools
Your email, your invoicing tool or an export from it, and your banks. Your accountants do not have to change anything: they keep sending the returns as they do now.
How it is built
Recalculating and comparing are done by deterministic programs, not by the AI model. Every figure says which document it comes from, and anything inferred is marked. If a piece of data is missing, it is not filled in with the accountants' figure.
It covers Spanish tax forms 303, 111, 115, 349, 202, 200, 390, 190, 180 and 347, and reviews only the ones each company files.
The questions for the accountants go through adversarial validation: a second agent checks them against your data and the published rules before you see them. That way your accountants do not receive doubts that already had an answer.
Bank transactions arrive pseudonymised, with the tax category visible and without names or account numbers. Payslips are read in a temporary folder that is deleted at the end.
Deadlines are computed by a program from the tax calendar, using the next working day. It knows the national public holidays; regional and local ones it does not, and it says so.
Frequently asked questions
Does it replace my tax advisers?
No. Your accountants prepare and file the returns, as they do now. The agent recalculates them with your data and tells you what does not add up before you sign.
Does it file or pay any tax?
No. The agent does not file, sign or pay, and does not log into the tax office's online services. It only reads, recalculates and alerts.
What happens if it finds a difference?
It tells you which box, by how much and the likely cause, and leaves the question ready for your accountants. If it is a wrongly booked item in your invoices, it tells you so it can be fixed at the source.
Which returns does it review?
Whichever of these your company files: Spanish forms 303, 111, 115, 349, 202, 200, 390, 190, 180 and 347.
