I found something look like bug

Please see screenshot tax calculation marked

It has correct calculation - what’s wrong?

The second line appears to include net_total + (.09 * 5.45)

Does it change after saving?

After saving not changing calculation wrong 0.45+5 should be 5.45 but showing 5.90 which is outstanding amount in first row showing correct

Hi @vikashji

I agree with @orey-aajaamu

Net of Invoice = 5
SGST = 9% of 5 = 0.45. Total is now 5.45
CGST = 9% of 5 = 0.45. New Total is now 5.45 + 0.45 = 5.9

So calculations are correct. Can you tell us what you are expecting and the calculations behind it

This would be true if tax was against grand_total. It’s supposed to be on net_total (which is not impacted by taxes).
