I would really appreciate some help to ascertain whether my partner and I are being charged the correct income tax and national insurance contribution deductions.
I started employment on 1/5/17 (1 month after tax year start), and my partner 3/7/17 (3 months after tax year start).
Below are the deductions from our respective wage slips.
Me: annual salary £35000, tax code 1150L.
- May: Gross pay: £2917 - Income tax: £200.20 - NI: £268.36 - Net pay £2448.44
- June: Gross pay: £2917 - Income tax: £391.80 - NI: £268.36 - Net pay £2256.84
- July: Gross pay: £2917 - Income tax: £391.80 - NI: £268.36 - Net pay £2256.84
- August: Gross pay: £2917 - Income tax: £391.80 - NI: £268.36 - Net pay £2256.84
Partner: annual salary £29500, tax code 1150L.
- July: Gross pay: £2458 - Income tax: £0 - NI: £213.60 - Net pay £2244.40
- August: Gross pay: £2458 - Income tax: £24 - NI: £213.60 - Net pay £2220.40
In regards to the above, I believe the calculations for my payslips to be correct taking into account my personal income tax allowance of £11500 for the year spread over a 12 month period.
When using the same formula for my partner I get this result for August income tax: £25.20, NI: £213.36, yet her employer has provided them as income tax: £24, NI: £213.60 respectively. Is her employer rounding numbers up and down?
