Most tax apps answer the wrong question for small businesses: they show the big headline number for large companies. Your rate is the SME rate, with its thresholds. Most apps bury it or skip it entirely. - Filter one, brutal and simple: does it show SME rates separately? One number per country, delete it. - You need the reduced rate, the threshold that triggers it, and whether it is profit, turnover, or headcount based. - Coverage of your actual shortlist beats global coverage. A great eight-country app beats a mediocre 200-country one. - Freshness: SME regimes change more often than headline rates. Governments fiddle with thresholds constantly. - Export: you will want the shortlist in your accountant's inbox. Screenshot archaeology is not a workflow. The app is a lens; the table is what matters. Ours tracks SME rates across 212 jurisdictions, free. When the lookup becomes a real decision, IncorpTrack registers your UK or Singapore company for $49 plus the government fee.
