Question
Why would tax PAYE be different for the same salary in 2 different months with no tax code change?
The salary is the same, the only difference is the mileage reimbursement, this should not be taxable, Niable or pensionable. NI, pension remain the same, but tax is much less this period than last period - do you think quickbooks is thinking the mileage is taxable? The tax code is also the same between the 2 periods.
