calculate_osvc_taxesread-only | Computes the 2026 income tax, social and health insurance doplatek for a Czech OSVČ (self-employed person), given what they've been paid so far this year and their situation. Also returns VAT registration status, a regime comparison, next year's advances, and a filing guide, with an explanation in the requested locale. Income counts when it's actually received into the account, not when it was invoiced (cash basis), so 'income' should only be what's been paid so far this year, and 'monthly' is a separate estimate of what's still expected between now and December. For example, income: 300000, currentMonth: 6, monthly: 50000 means 300 000 Kč has been received through June, and about 50 000 Kč/month is expected July through December on top of that. Call get_field_guide first if you need to explain an option to the user before they've decided on a value. |
get_field_guideread-only | Returns every field calculate_osvc_taxes accepts, grouped the way the web calculator groups them, with the same label and explanation shown in its tooltips. Use this to explain an option to the user before they've decided on a value, without running a calculation. |
