A few tools worth bookmarking. Run your own numbers, no signup, no strings attached.
These tools provide an estimate based on the inputs you enter and standard statutory assumptions. While we have taken due care in building them, we make no warranty as to their accuracy and accept no financial liability for actions taken based on their output. They are not a substitute for professional advice and should not be relied on for filing a return, issuing a demand notice, or any other formal purpose. Consult your CA to confirm figures before acting on them.
If your situation doesn't fit a standard calculator, a Partner can walk through the numbers with you directly.
