The Taxman Cometh

So, they've given me six months to fill it in but I want to have it done before the end of the June. It will take me that long to work everything out. From what I understand, there's very little for me to tick, let alone worry myself about the additional form where they give detailed instructions on how to write out sums greater than one million. I'll be lucky if I'm taxed at all. Stripping isn't as profitable as it used to be...

Now, do thongs count as plant and/or machinery?
