Top 10 weirdest tax rules around the world!

Countries across the globe have justified deductions, extra percentages and wacky ways of coming up with tax revenue. Here's a countdown of the strangest tax laws around the world.

10. South Africa: World Cup tax bubble

Soccer may be the world's sport, but it's also one of the world's best bargains when it comes to taxes—at least for FIFA.

The BBC reported in 2010 that as part of bidding for the World Cup, host countries must agree to exempt FIFA, the organisation that puts on the World Cup, and its subsidiaries from paying taxes to the host country. The taxes this applies to depends on the country, but in South Africa in 2010 the taxes exemptions were fairly sweeping.

The BBC reported that the breaks "[relieve] FIFA, its subsidiaries, and foreign football associations which are taking part, of income tax, customs duties, and [value added taxes]. World Cup preparations have cost South Africa an estimated 33 billion- nearly £3 billion. This also applies to the various organisations designated as FIFA's commercial affiliates, licensees, host broadcasters, broadcast rights agencies, merchandise partners, service providers, concession operators and providers of hospitality."

Technically this extends to any country that has hosted a World Cup. Brazil signed a similar tax agreement for hosting the games in 2014. When Germany hosted the games in 2006, FIFA accrued 2.8 billion Swiss Francs (£1.72 billion) in the four years up to and including the competition, yet paid only 1 million Swiss Francs (£613,500) in local taxes.

9 France: Google tax

Europe is relatively more protective of privacy most, which has often led to more controls on tech companies. However, compounded with the economic crisis, European countries are more likely than ever to go after big tech companies who they say are making revenue off their citizens without paying due taxes. These taxes are largely known as "Google taxes," though they apply to any large Internet-based company.

France has been the most outspoken nation in attempting to tax Internet companies like brick-and-mortar companies. Previously France contemplated a "culture tax" on smart phones and tablets made by Google and other tech companies in hopes of gaining revenue for a cultural fund.

A recent iteration of the Google tax is France's assertion that the company owes the country $1.35 billion in back taxes for circumventing the tax laws by diverting much of its French revenue to Ireland (where there are lower taxes). Google's Paris offices reported its revenue was $260.53 million in 2011, while analysts believe revenue was more like $1.89 billion.

After revelations of NSA spying, on top of suspicious tax moves, it's likely that France and large Internet companies will be sparring financially for years to come.

8. Ireland: Artist exemption

Want to be a starving artist? You'll go a little less hungry if you find your muse in Ireland. In order to boost the arts, income earned by writers, composers, visual artists and sculptors from the sale of their works is not taxed, under certain circumstances.

Artists must file a claim with Revenue Commissioners, who determine whether the work is original, creative, and has cultural or artistic merit. It also must fit within the five following categories: books or other forms of writing, plays, musical compositions, paintings or other similar pictures, and sculptures.

Wondering how tax people judge art? Here is a sampling of the criteria:

A work has cultural merit if: Its contemplation enhances the quality of individual or social life as a result of its intellectual, spiritual or aesthetic form and content.

A work has artistic merit when: Its combined form and content enhances or intensifies the aesthetic apprehension of those who experience or contemplate it.

The maximum exempt is €40,000.

7. Britain: Culturally British film tax break

Britain wants to keep its culture alive in films—so much so that it has created a tax rule that gives tax deductions to films deemed "culturally British."

The process is more complex than flying a British flag or setting your movie in London. All films that would like to claim this deduction have to register their production where it is rated through a mathematical "culture test" weighted as follows:

Cultural content (up to 16 points).

Cultural contribution (up to 4 points).

Cultural hubs (up to 3 points).

Cultural practitioners (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 (four points), film represents/reflects a diverse British culture, British heritage or British creativity (four points), and original dialogue recorded mainly in English language (four points).

6. Denmark: Cow flatulence tax

Most people think of congested American highways or black-smoke-belching factories as the cause of greenhouse gasses. But the European Union has found another culprit: cow gas.

Extensive studies have found that the methane released once cows slowly digest greens may account for up to 18 percent of Europe's greenhouse gasses. The issue is compounded by slaughterhouses, which concentrate large quantities of methane gas in one area. In order to curb the cow fuelled greenhouse gas epidemic, several EU countries have adopted taxes on each cow. The highest rate? Denmark, where each cow will cost you up to £85

5. Sweden: Baby names need tax agency approval

Choosing a name for your new son or daughter is a difficult decision, one that requires at least the mother and father to be in agreement. In Sweden there is one more necessary party: the Swedish tax agency.

Swedish people are required to have their child's name approved by the Swedish tax agency before the child turns five. If parents fail to do so, they can be fined up to 5,000 krona (or £470). The law originally was put in place in 1982, reportedly to prevent citizens from using royal names, but the law states the rationale is that by approving the name the tax agency can protect a child from an offensive or confusing name.

What kind of names are unacceptable? The tax agency has rejected "Ikea" (due to potential confusion) and "Allah" (due to potential religious offense), as well as "Brfxxccxxmnpcccclllmmnprxvclmnckssqlbb11116", which one child's parents attempted to name their child in protest of the law. However, "Google" and "Lego" were recently allowed.
