We have an accountant in Germany. They are good and they are (compared to any UK accountant) very cheap. That is because there is a single tax code - a book you can buy that has all the tax laws. I have (an out-of-date) copy somewhere on a shelf. In Germany, there is a rule for everything and everything has a rule - and taxes are no exception. You may not like every rule, but at least they make sense and you know where to find each and every rule.
The UK is different.
The UK tax code is now some 10 million words, according to the accountancy body Icas and no single human being understands more than a small fraction of it. The 2015-16 edition of Tolley’s yellow and orange handbooks (the accountant's bible) comes in at a record 21,602 pages.
There are special rules for rented, leased and borrowed hairdressers' chairs. There are special rules for equestrian businesses. There are special rules for fuel-tax for heating a boat and they are very different to the rules for putting fuel into a tractor, which are different again to the rules governing fuel tax for a digger. And if you are in the creative industries, the number of exceptions, rules and other tax implications are staggering. It’s a hopeless, dreadful situation.
There are a whole series of tax rules that gives tax deductions to films deemed culturally British. Films that would like to claim this deduction have to register their production where it is rated through a mathematical culture test calculated as follows: Cultural content (up to 16 points). Cultural contribution (up to 4 points). Cultural location (up to 3 points). Culturally active people (up to 8 points).
Films must score at least 16 out of 31 points to get up to a 25 percent tax break. Here are some examples of film characteristics that qualify: film set in the UK (you score four points), film reflects a diverse British culture, British heritage or British creativity (you score four points) and original dialogue recorded mainly in English language (you score another four points).
By linking your film to other business activities, it is possible to make a movie and then show it to nobody and just throw the damn thing in the bin (or delete its files) and still make a profit!
Anyone trying to run a business without an accountant or five, is begging for trouble in the UK.
