IAS officers start at the junior scale of the 7th Pay Commission pay matrix.
Basic pay rises with each promotion — from district postings up to secretary-level scales.
In-hand salary includes dearness allowance, house rent allowance and travel allowance.
They also get official residence, vehicle and staff as per posting.
The exact pay per level is given in the official pay matrix.
Ignore third-party ‘in-hand salary’ claims — deductions vary by posting and pay commission revision.
