I am planning to start out as a piano teacher in the Autumn.
It would be the only income for my family (single parent)apart from tax credits.
Obviously I have no idea yet how much I may make/how many pupils I'll be able to take on etc. etc.
Does anyone know, who do I inform (for tax purposes) about my income? And do I have to estimate earnings for the tax year, or state my earnings for the previous one?
Or do I not need to inform anyone as long as I earn below a certain amount?
TIA
