I have a question on regards good character when it comes to tax check and national insurance contribution
In the 5 years qualifing period i have about 2 years of no work and three other years of work outside the uk with non uk based company
In the National insurance record it shows gap in all these years , as i believed im not obligated to pay national insurance as i never worked in UK but at the same time i had to pay tax in both countries which was done, but for one of the years i filed late and paid penalty for late payment but for some reason i have not gotten late filing penalty yet
Do you think this will impact my good character in the application, do i need to pay the voluntary NI , and do i have mention the late filing of one of the tax years

Thanks
M
