Frequently asked questions

Which countries does KAZAALBAIDA support?

KAZAALBAIDA covers Spain (Modelo 100 and 303), France (Formulaire 2044), the United Kingdom (HMRC SA105), Portugal (IRS Categoria F) and Italy (Modello 730 / Redditi PF). Each property is routed to its jurisdiction automatically, so mixed portfolios stay compliant without extra setup.

Is there really a free plan?

Yes. The Free plan costs nothing forever for one property — no contracts and no setup fees. Ruby, Sapphire and Diamond plans add more properties, bank statement sync, and the full multi-country tax engine when your portfolio grows.

Can I sign leases digitally?

Yes. KAZAALBAIDA includes a native electronic signature engine: generate the lease for your jurisdiction, send it to your tenant, and both parties sign online. The signed PDF is stored with the contract, ready for any audit.

Do I need a credit card to start?

No. Create your account, add your first property, and start tracking rent, expenses and profitability immediately. You only choose a paid plan when you need more than one property or the advanced tax engine.

How are the tax forms generated?

The tax engine pre-fills the jurisdiction-specific form (Modelo 100/303, 2044, SA105, IRS Anexo F, Modello 730) from your properties, leases, tenants and expenses. You review every figure before filing — the platform automates the calculation, never the decision.
