We have seen some cases accusing the accounting for false financial reports etc.
Since we do not have all details, it may not be easy to determine whether the concerned accountants had done anything wrong.
Although I do not accept the general concept that most Chinese firms had several sets of accounts, yet it is certain that some of them would be so.
Of course, anyone, Chinese or American, general merchants or millionaires are always trying to avoid paying tax. Just read the tax shelter cases by KPMG, it is easy to know that even Americans are not exception.
Why people want to avoid tax? Let's not spend time talking about patriotism, that is something in wartime only. Anyone may not be happy to pay part of the earning, especially when the total tax reached a big amount.
Tens of years ago, I met a female manager from USA. She told me that many people who had similar level like her were not aggressive anymore because they would get very little with any increase of earning due to the high percentage of tax above their level.
The next person to mention was a photographic student of my photo course years ago. He had a company and was recruiting an accountant. He said that during his interview for accountant, the applicant had refused to prepare false accounts to avoid tax first. After a few months, the applicant came back and accepted his terms.
Tax shelter is a nice term that looked legal. Of course, we know that it is not so even that had been a tool for the top auditor firm and a lot of big corporations might have joined too.
There are many ways; some are specific for certain conditions that create a lot of gray zones. We may blame those lawmakers. Yet we must know that the business world has evolve much faster than anyone can master. Many governments have to attract foreign investment or to support various development and therefore offering certain policies that would not be harmonic with the existing taxation regulations.
I do believe that governments are confident with their taxation departments and anyone trying to get away would be caught sometimes later.
Anyone who has enjoyed tax shelter or any similar way to avoid tax might believe that the taxation department would be fooled easily. Remember that all taxation departments have millions of company reports and their leaders have the same qualification if not higher than any accountant or auditor. Perhaps some accountants and owners never have the chance of looking at such huge volume of data and never be aware that statistic is a great tool to investigate or locate any suspects.
If you have cheated your taxation and not yet caught by the government, it is not that you are cleverer, it may be the maximum penalty for your case is not listed on top yet. See, it is costing again that determine who would be selected for trial.
There is no game theory to offer any guide. But with gambling experience, it is just not worthwhile to bet for a little gain against possible huge loss.
