I'm about to sign on for the first time but I'm a bit worried about the attention it could bring. Recently I've had a few cash in hands jobs. I wasn't claiming benefits at the time and I didn't declare this income so I paid no tax on it. Over the past couple of months I paid that money into my bank account, about £3500. If I start collecting the dole is it likely that someone will start to take a closer look at my financial history and ask me to pay tax on that money?
