Sir/ madam
I have doubt

i am having HRA 4300₹ p.m
annually 51,600₹

House rent shown 12 months ×12,000 ₹= 144,000₹
My 10 % salary comes to 73590₹


To reduce HRA fully 51,600₹
i have shown 12,000₹ p.m as house rent paid

my doubt is
i need to submit any documents like house rent paid receipt or Bond, if i have shown total house rent above 1 lakhs per year ??
is that mandatory ??
i am government employee...

kindly clarify my doubt
