Since I became a higher rate tax payer I have never actually paid 40% tax as my maternity leaves have meant that I actually didn't get enough in the various tax years (I took my full entitlement to no pay leave).
Am now back at work, and will be paying 40% in 2007/08. I don't do a tax return because my job is the only income I get - don't have shares or rental income etc. However, I do have savings which will be taxed but at the basic rate - should I voluntarily be doing a tax return to pay additional tax? Stupid question perhaps - but what happens if I don't?
Any ideas?
