Back date self-employment

wrf12345

Hi, during the period 2009-2018 I received a small amount of eBook royalties via US bank account and put these through on the international pages of self-assessment so I could reclaim the US tax paid at 30 percent. No UK tax to pay as I was under my personal allowance (apart from this living off savings). No problems except I am short on NI contributions and would have been better off declaring self-employment and doing voluntary Class 2, which I intend to do from now onwards (via UK bank acc) but wonder if I can back date that start date (are there penalties if the income has already been declared and no tax to pay?) so I can pay voluntary Class 2 rather than Class 3 for those eight years? eBook income is around £100-500 per year but could be ramped up a little with promotion. Money from US has all been moved to UK during that period.

Do you have any other income? Or it is just the £100-£500 per year...

Yes, interest from savings and some CG (all declared) but all covered by personal allowance and CG allowance, all tax records up to date and no problems.
