Hey everyone! 👋

I am a freelance developer from India, and recently I got incredibly frustrated with how complicated it is to manage taxes and invoices here. Every time I needed to calculate my Advance Tax or generate a basic GST invoice, I was hit with a paywall or forced to sign up for expensive software like Zoho or ClearTax.

So, I spent the last few weeks building my own suite of tools, and I decided to open-source them and make them 100% free for the community.

No login required. No paywalls. No watermarks.

🛠️ What I Built:

Tax Calculator (Section 44ADA): If you are a freelancer claiming 50% tax-free income, this visually calculates your exact tax brackets under the New Regime.
Advance Tax Calculator: Calculates exactly when and how much you need to pay for your 4 advance tax installments so you avoid Section 234B/C penalties.
Salary vs Freelance Calculator: A cool tool that calculates exactly how much you need to charge hourly/daily to match your corporate salary (accounting for unpaid leaves and expenses).
GST Invoice Generator: Generates a legally compliant Indian tax invoice as a beautiful PDF.
Freelance Contract Generator: Generates an NDA and Service Agreement.

🔒 Privacy First

I built it entirely using React and client-side logic. That means no financial data is ever sent to a server. Everything calculates instantly right in your browser.

I'd love for you guys to test it out. Let me know if the tax math checks out or if there are any other calculators you wish you had!
