Computing income post early retirement

Hello,

I hv taken early retirement (56 yrs) last year & need your help to ascertain how to compute my income for this year.

I hv no pension.

My children transfer funds to my acct for my exps. They also remit funds to me to repay their education loan which i do.

I hv kept my retirement funds including PF in FD. I hv given form 15 to bank for this year.

How do i compute my income for tax calculations ? Do i consider all credit entries in my acct as my income ?

Pl advice

Tks n rgds

Uday
