TaxSight - Free UK tax calculators with 200+ pre-built salary pages

Hey everyone! I'm Zohaib, a developer based in Manchester, UK. Every April when the new tax year starts, millions of people Google things like "35000 after tax" or "stamp duty on 300000." They land on sites covered in ads with outdated rates. I built TaxSight to fix that. What makes it different: → 12 calculators covering take-home pay, stamp duty, VAT, mortgage, pension, CGT, corporation tax and more → 136 pre-built salary pages (£15k to £150k) — instant breakdown for any salary → 43 stamp duty pages for every property price → 10 plain English tax guides → All HMRC 2025/26 and 2026/27 rates verified → Everything runs in your browser — zero data collection The tech: Next.js with static site generation, hosted on Vercel. The entire tax engine is one TypeScript file. 200+ pages in the sitemap, all pre-rendered at build time. 100% free. No signup. No ads. Would love your feedback — what calculators should I add next?
