Some background first
=================
I received a change of tax code notice from HMRC in August 2011 telling me my tax code was changing to 714L because I have private health care with my employer. My code changed from September 2011 pay onwards (I get paid monthly).
The Detail
=========
This month, I get a bonus and am also getting a pay rise which is backdated to the 1st October 2011. So the figures on my payslip are;
Monthly Salary: 3052
Bonus: 2700
Back Pay: 500
On this I have paid tax of £1679.06 and NI of £406.80. The NI is probably ok but the tax seems extremely high to me. On a "normal" pay, I would expect to be about £450 in tax (up to £490ish with pay increase). So my gross salary has increased by 2x for this month but my tax has increased by about 3.7x
I was told my tax code was 714L but it is actually 714L M1. This is obviously to catch up on payments I'm due for tax on the healthcare insurance benefit but I'm assuming my tax code was set at this on the assumption my monthly pay was the same throughout the tax year. However on this one month, I seem to be getting hammered for tax!!
My employer has said the tax is right, which is correct, the tax paid is the correct amount but what I'm getting at is surely the amount of tax I've paid this month is over and above what I should have paid whilst catching up on tax for my private healthcare.
Not sure if you follow this or not but do you get what I mean and do you think I've paid too much tax?
