Cattle - I agree maternity leave when you're self employed can be a disaster. That's what I meant about less security. I just can't see how the 90% thing could be regulated. If it could, I'd be first in line to claim it, don't worry! (if I was going to have any more kids, which I'm not!)
Re the average earings from your tax return - I suppose you could average those out, but I only had 2 self-employed tax returns before I had my first child, both of which were for very good years, financially, so 90% of the average weekly income would be quite good. With my second child, the intervening four years tax returns were about 50% of the first two years, so are you saying I should have got 50% less maternity pay?
Pus as a self employed person, INCOME is often very different from PROFIT (ie what you pay tax on). My profit for 04-05 was £325 for the year. I certainly earned more than that though!
I have a business account that's separate from my personal bank account (which is a joint a/c with my DH), If you don't have one then how can you tell what your 'salary' is? Do you think you should be able to get 90% of your income (ie the money you keep) as maternity pay, or 90% of your taxable profit? If that was the case for me I'd get f-all! So I'm thankful for my £106/week.
Regarding expenses, you CAN get away with more than an employed person. An employed person, generally speaking, drives their car or takes the train to and from work and pays for that with their after-tax earnings. They buy a computer for little johnny to do his homework and can't put it though their boss's books. I have put a digital camera, DVDs, postage, loads of things through my business beacuse I needed to use them for business ONCE and then kept them for my own personal use.
