I can't say as I claim for anything strange
We have 7 rooms, one of which I claim as my office, ergo 1 seventh of my housing running costs gets claimed for. Got no plans to sell the house, so the implication that the tax man may want a piece of it should I do so doesn't bother me
I claim a tiny part of the house phone costs and about 25% of my mobile phone, bills are itemised, if the tax man decides to take an interest in you will come unstuck if you claim for more than you should
I was chewin' the cud' with a customer last month, telling him I was just about to send of my tax return, all filled out courtesy of Which Tax Calc.
He told me that the Tax Man decided to investigate him, went back the 6 years and he wanted everything.
They start out assuming that 100% of everything you are trying to claim for is personal and it is up to you to prove otherwise that the percentage of costs you are claiming are justified.
You can claim and get away with loads of things, or at least you can think you are getting away with it! Your accountant, should you be lucky enough to have a really good one, will pull you up if he see's anything that you can't claim for, but he can only go on the things you give him, and the tax man won't be putting the thumbscrews on him, its you he will be interviewing
So even if your return is rubber stamped and accepted, its probably because they haven't pulled your accounts out of the hat for closer scrutiny this year.....but they might next year
It's like Russian roulette, as each year goes by without a visit from him, the sweats get worse until you get the confirmation they agree with your return. you can breath easy for another 12 months, but they'll be back, they'll always be back
