An accountancy website that starts with the decision worth tens of thousands
Choosing between the lump-sum, the progressive scale and the flat tax is the one bookkeeping decision that can cost more than a decade of accountancy fees — and it is made once a year, by 20 February, usually on the strength of a remark from somebody running a completely different business. The site works out all three regimes on the client's own figures and shows the gap in złoty: at 300,000 turnover with 20,000 of costs the lump-sum wins by 36,000 a year, while at the same turnover with 150,000 of costs it flips and the progressive scale is 25,000 cheaper. Sometimes the gap is a few hundred złoty and there is nothing to discuss; the page says so plainly instead of pretending every switch is a saving. The enquiry form repeats the same arithmetic server-side and attaches the result to the message, with a subject-line tag carrying the size of the discrepancy — sharpest when the client's current regime is not the one the figures point to. The look is a comparison sheet rather than a brochure: three columns, amounts in tabular figures aligned right, the winning column edged in green. The legal-status date sits beside every result and in the footer, because a tax calculator without one is a trap — next year those numbers will be wrong and will look exactly the same. That date is also the single thing requiring manual upkeep: when the rates change, they are edited in the configuration together with it.
