Estimates for cross-checking only, not tax advice; the accountant's filing is authoritative. The IRPF bracket table is a state+regional approximation — adjust it in Settings for your region. Rent (habitual residence) is tracked but never estimated — regional deductions vary; raise it with the accountant.
