Calculate whether EET OFF pays off
eet_calculate_eet_off
Compare the EET OFF surcharge (1 400 Kč/month added to the flat-rate tax instead of registering sales) with the real cost of registering sales (time × hourly rate + POS cost + hardware spread over 3 years). Handles businesses that start mid-year (surcharge only from the start month). EET OFF is only for natural persons in band 1 of the flat-rate tax with income up to 1,000,000 CZK; for others the tool returns eligible=false with the reason. Args: - flat_tax_band (1|2|3|0): 0 = not in the flat-rate regime. - yearly_income_czk (number): self-employment income per year in CZK. - start_month (1-12, default 1): month the business starts in 2027; 1 = whole year. - minutes_per_day (default 5), work_days_per_month (default 21), hourly_rate_czk (default 300), pos_cost_monthly_czk (default 0 – the EvidujZdarma POS is free), hardware_one_off_czk (default 0). - response_format ('markdown'|'json'). Returns: eligible, reason (if not), verdict ('eet-off'|'evidence'|'tie'), surcharge_czk, evidence_cost_czk, difference_czk (positive = evidence costs more), months, flat_tax_monthly_2027_czk, rules (deadline, binding year, exceeding 1M, exit).
