Hi. Last tax year I had a good income. However during the summer I lost 2/3 of my income. I've done my tax return and I'm not sure I can afford the ni class 2 and 3 payment by the end of January. Would they allow me to pay half one month and half the following month? Or spread it out.? I've sorted for April's 2016-2017 tax year. And no how much I have to save to pay for that. Any help appreciated. X
