A lot of accountants and tax consultants will give you a free initial meeting so you can discuss things, get advice on what records to keep and an idea as to how much things will cost. There are quite a few people running small practices from home and they will be the cheapest and have quite enough know-how and resources for the smaller business. i would be wary of asking at the tax office without at least getting back-up information elsewhere. They have a quick staff turnover which means that the person you see may not have a lot of experience and, whether deliberately or accidentally, they are more likely to tell you what you are obliged to declare, rather than what you can claim!
