Skullcap

So... Is it safe to assume that HMRC knows about the total amount of State Pension and Work Pension I receive? Do I need to file a Self Assessment on my Pensions income? Can I assume that HMRC will send a demand for tax if I need to pay tax on my Pensions?

I did not see any industry where I could reasonably fit the category of a postal worker. How do I claim a tax rebate for uniform laundry expenses over the last five years?
