I run my own business as a sole prop in my own name. I read somewhere that if my taxable income is below a certain threshold for the year, that I do not need to register as a provisional taxpayer. Is this correct? I was under the assumption that because I earn income other than a salary (from carrying on a trade) I am automatically a provisional taxpayer?
If I am below the threshold and do not need to register, then how will I know this before hand? For example, for the 2015 tax year, I will only know if I am below the threshold at the end of the year, being Feb 2015. By then, I would be late in submitting my provisional tax returns (due in Aug 14 and then Feb 15)?
Is there any harm in submitting provisional returns when not necessary to do so?
