Most will be extremely lucky if they get that P60 issued within the next 2 weeks
The deadline for End-of-Year Employer returns (P35) is 19 April
The P35 is essentially a summation of the individual employee details on P14 (which is same as P60)
Employers are required to issue form P60 to each employee by 31 May 2014.
With a very large employer who knows when it'll get issued....
Anyway a P60 isn't mandatory but pay slips and corresponding bank statements are mandatory.
