> Just out of curiosity, why would tax competition be considered bad?

In the European union, where funds are easily transferred between subsidiaries in different countries, tax competition by individual member states can have particularly harmful effects on the public economy as a whole.

In a typical multinational corp tax avoidance scheme, a coproration has a subsidiary A in e.g. Ireland and has a very small corporate tax rate on profits. Then another country, e.g. Netherlands gives subsidiary B a tax break on some commodity, typically an IP licensing scheme of some kind.

Subsidiary A licenses some IP from B, and the licensing fees are conveninently 100% of the profits of A, so they're not making a profit in Ireland and don't have to pay tax there. Subsidiary B gets all their profits from IP licensing that pays hardly any tax in the Netherlands.

Add a few subsiriaries and loan arrangements between them (free movement of capital in Europe is one of the fundamental pillars of the EU), and no taxes get paid and all of the profits get funneled into a tax haven such as Bahamas or Caymans.

So while you'd think that tax competition would just be a fair competition when talking about individual countries, at EU scale it ends up being a race to the bottom where a few select countries (Ireland, Netherlands, Luxemburg) get a nominal fee from the multinationals but all European states end up losing billions in tax revenue.

And then there's also the corruption aspect. These tax deals aren't a gesture of goodwill.

This is not about tax competition, this is about abusing tax loop holes and trying to avoid paying any tax at all. E.g. before 2015 Amazon declared their entire European income in Luxembourg and payed about 1 percent of tax on that money. This way other (much bigger) European countries like Germany and France lost billions.

You can't have tax competition and freedom of movement of companies, goods and capital. It's the tradeoff in the EU for removing all protective internal tariffs.

(The US avoids much inter-state tax competition through federal taxes)

The US has tons of inter-state tax competition; federal taxes just comprise the base rate, not the total taxation rate. State governments fall all over themselves to offer special incentives for companies to come in. Or stay, in some cases - a local employer has been here almost 80 years, yet the state and local governments still feel they need a massive multimillion dollar tax break or they'll pick up and leave.

It is bad because it decorrelates the country you make a profit out of from the country you pay taxes on this profit.

The people paying for your product are able to buy it because they live in a country that provides for them, through added value, jobs, health care, infrastructure and so on. If you want to profit from these people's buying power, then you have to conform to that country's rules of business, that's all.

Apple is very happy to make huge sells of iPhones thoughout France, Germany, Italy and such countries, siphoning money from their people to Ireland, without ever contributing as much into the local economy. They employ a few hundred people in Apple stores and hotlines, but compared to their profit it is just ridiculous.

Is that really the case? Apple operates in Ireland and it pays taxes there based on a certain competitive rate it has. If Apple sells phones in certain countries, it has a network of suppliers there and it pays taxes on their business operations there. It seems that you're making the argument that the phones have to be produced in every country where they're sold in order to eliminate trade deficits (the so-called decorrelation of profits and taxes that would result from the importing of a product). But the only way for the other countries to get that tax revenue would be to be competitive enough (through competitive tax rates, availability of talent, infrastructure, legal system, etc.), so that Apple would be incentivized to open offices and move their R&D and pay taxes there. It seems you're arguing that these other countries shouldn't have to compete on these criteria, but should somehow be entitled to that tax revenue or at least to protectionist measures that would make sure that Apple has no incentive to go anywhere else, purely based on the fact that willing buyers purchase Apple's products there. I'm not sure that's a very strong argument because it basically amounts to saying that if you don't force Apple to give some form of a discount to these buyers, they won't be able to buy the product in the future...

The thing about transfer pricing is that it makes the "location where value is created" completely arbitary. It's not where the R&D is done, it's where the shell company that holds the patents is registered.

Apple subsidiaries in random countries selling phones don't pay taxes because they don't make any profit. They don't make any profit because they're "charged" an amount for the phones (and IP, branding etc) that exactly equals the sales.

"decorrelates the country you make a profit out of from the country you pay taxes on this profit": taxes are due where value creation took place. That's called a rule. The EU decided the rule should be changed after the fact, retroactively.

"people paying for your product are able to buy it because they live in a country that provides for them": wow... really? I know governments love considering people's money as theirs, people's lives as theirs, but that's a bit far stretched maybe? I'm not any country's liability. I'm a free man in a free society. Aren't you?

"Without the Glorious State, you wouldn't have had any consumers to make you wealthy!"

Here's a business producing commerce-enabling technology in an extremely valuable manner, hence the profit. Consumers exchanged their earned, post-tax savings for those things and paid additional tax along the way. To act like governments were short-changed is preposterous. It's "you didn't build that" taken to the extreme, and borderline extortion.

Because cartels means something specific to a group of market players and tax means something specific to a nation state.

The two are vastly different, and the first is tolerated only by the latter because it's the best way we know to bring order and organization to trade.
