AI tax software that works for you.
Your agent gathers invoices and handles tasks through WhatsApp. The software keeps your income and expenses organised. Melso’s human professionals prepare and file your included Spanish tax returns after you review and approve the draft in the app.
Am I missing any invoices from September?
Two documents are missing from your records. Shall I look for the broadband invoice in your connected email?
Yes, find the broadband one.
I found it. I’ll prepare the record for you to review. For the other expense, I need its supporting document.
Your agent, software and accountant. One complete service.
Give your agent work to do, keep your records organised and delegate tax preparation and filing to human professionals. Melso brings task execution, tax and accounting software and a gestoría, Spain’s professional tax service, together for self-employed people in Spain.
Invoices and expenses in order.
Add invoices and receipts, check their details and correct anything that needs attention. Keep the documents alongside your records.
Explore invoices and expensesGive your agent work to do.
Ask through WhatsApp for an invoice from your connected email, a set of documents or another task. You authorise the connected accounts and review the result.
Meet your agentTax returns handled by people.
Melso prepares and reviews the included returns. You approve the exact version in the app, then a professional files it with the required authority.

A complete service makes clear who does each task and who takes responsibility. Here is how Melso shares the work. When comparing another option, check both its software and the professional service you contract.
| Work | Software alone | Melso |
|---|---|---|
| Documents and records | You organise the process and check the data. | The agent helps gather and organise documents; you can review your records. |
| Tax review | You review the treatment or hire a professional. | Professionals review the included returns for your activity and tax profile. |
| Approval and filing | Agree who reviews, who files and how you receive the receipt. | You approve the exact draft in the app; a professional files it. The real filing receipt confirms submission. |
| Scope and cost | Add the licence, extras and professional advice if needed. | Compare Pro and Plus and confirm included forms, tax regimes and services before subscribing. |
Authorising a draft and filing it are separate steps. A calculation or an agent’s reply is not a filing receipt from the AEAT, Spain’s tax agency.
How to choose the best AI tax software for your work.
Start with your usual tasks. The right option depends on what you need to manage and how much work you want to delegate.
- Try an invoice and a receipt: check the details and how you correct a mistake.
- Confirm the service covers the forms and tax regimes relevant to your activity in Spain.
- Ask who reviews and files, and where you will receive the filing receipt.
- Compare the total annual cost and how you can export your records.
Built for self-employed people in Spain.
Pro and Plus combine the tax service, agent and tools, including the annual income tax return, Renta (form 100). We confirm scope before you subscribe. Not every form, tax regime, information return, payroll service or tax notice is included; AI usage has a monthly limit.
