For some reason I decided to look again at my p60s (end of tax year pay summaries) and put the figures into a NI calculator for the tax year as I noticed that some years, despite earning very similar amounts the NI varied quite wildly.
In the Last 8 years, according to various calculators, I've overpaid over £2000.
The last 5 years, some years its £150, others it's nearly £500 totaling £1500.
I've looked online and can see that you can claim back money from the government but they prefer your employer to reduce your current rates instead.
As you can imagine I have no faith in my employers payroll services (other things have gone on which have led to a complete breakdown of trust recently).
Has anyone done this before, what would be a suitable timeliness for payroll to look into it and make the adjustments?
Also, I work for a large public sector body, 400+ people, I'm guaranteed to not be the only one affected. Is there an expectation of my employer looking into this for everyone, if not, I feel like sending an organisation wide email highlighting the issue but that might be used against me (employer has been doing some quite unlawful things and I've been quite vocal about my displeasure)
