S.15 The following incom shall be chargeable to income-tax under the head “Salaries” —
(a) any salary due from an employer or a former employer to an assessee in the previous year, whether paid or not;
So this should clearly be shown as your salary. I can understand the predicament here, it is on one hand taxable to employee and he should be self assessment tax thereon and on other hand employer is required to deduct tax at source while making the payment
I was reading an old judgement wherein it was held that advance tax should not be leviable on such accrued income. But there aint many judgement in this regards. Best is to follow S.15 to avoid litigation
Even the Indian Income Tax Act 1922 had similar provision ,w.r.t charging salary to tax on accrural basis
[Erstwhile provision, S.7 of Indian Income Tax Act 1922
The tax shall be payable by an assessee under the head "Salaries" in respect of any salary or wages, any annuity, pension or gratuity, and any fees, commissions, perquisites or profits in lieu of, or in addition to, any salary or wages, which are allowed to him by or are due to him, whether paid or not]
