everyone gets that rebate. once you cross, you pay tax on the margin by which you have crossed by the slab rate.I don't think so. Tax slab remains same for both 12.75 and 12.76L. Government gives rebate till 12.75L. So net tax becomes 0. Once you cross, you are not eligible for rebate. So you fall under slab rate and pay tax in slab rates. Please note this is on income and not limited to salary.
