Why it matters
Quarter end is prepared throughout the quarter.
Every invoice, expense and correction changes the result. Seeing an explained estimate before close helps find gaps without promising certainty where your circumstances matter.
How Bunnatic solves it
Forecast first. Forms second.
Bunnatic calculates from recorded Fiscal Amounts and keeps each field traceable to its sources. Compatible obligations depend on your profile and setup.
Tax reserve
You know how much to set aside before the deadline arrives, and you see it subtracted from available cash.
Box by box
Every amount on Form 303 has the invoices that originate it behind it.
Guided close
A checklist per quarter tells you what is missing before filing.

Copilot
Questions you can already ask
The Copilot answers with your figures and takes you to the screen where you can check them. Nothing runs without your approval.
Connected to the rest
With an advisor or by yourself, the engine is the same.
With an advisor, Records and documents arrive prepared. If you file, you can prepare and review compatible forms. Neither mode loses financial control.
An everyday example
Your VAT estimate rises after reconciling a missing collection. Bunnatic identifies the change and the invoices behind it.
The calculation remains reviewable and does not replace professional judgement where your activity or circumstances need it.
Any questions?
Does Bunnatic file the forms for me?
It prepares the forms with the amounts per box for you or your advisor to review and file. Filing with the AEAT remains yours.
How is the tax reserve calculated?
It adds the expected net VAT, the estimated income-tax instalment and the pending self-employed fee, with the calculation policy explained on each figure.
Which forms does it cover?
303 and 390 for VAT, 130 for income tax, 111 and 190 for withholdings when they apply to your activity. Each with its traceable detail per box.
What if I change a figure after reconciling?
The form is recalculated and Bunnatic points out which box changed and which invoice caused it, so nothing moves without an explanation.
