Prefacing this by saying I don't know so much about economics so please go easy on me.
Economists seem to overwhelmingly favour eliminating corporate taxes. As I understand, the reasons behind this tend to be that they're rather easy to avoid, and shift tax burden towards the cost of labour. I can sympathize with the idea that the status quo with multiple-deductions and rather easy profit-shifting isn't great, but I'm not convinced the proposed alternative will be much better.
Here lies my query: Wouldn't a 0% corporate tax just lead to people "incorporating" themselves and claiming spending as business expenditure, thereby bypassing income tax?
/u/RobThorpe explained the issue very well here:
One problem is so called "closely held" businesses. Let's say that I do business as a sole-trader, I don't incorporate my business as a firm. I employ many people and make a lot of money. By not incorporating I'm not liable to pay corporation tax. I'm only liable to pay income tax on my earnings. Suppose that corporation tax were reduced to zero. In that case I could incorporate my business at no cost. This is not a problem so far. In fact it puts small businesses on a level pegging with larger ones.
The problem here is that I can use the firm to remunerate myself directly and side-step income tax. I could, for example, buy my home computer through the firm for business use, but also use it for personal use. Every small businessman I've met does that. There are dozens of ways that I could push my personal expenses onto my firm. It's not fraud if I own the firm completely. Additionally, I can modulate my net profits to reduce my income tax and capital gains tax bills. I can invest in years where my income tax liability is high and take profits in year's when it's low.
For sole-traders the income tax laws usually regulate these things, but for firms they may not, or may not do it so well. If there's corporation tax then any oversights in the rules are not so important. That's because many businesses owned by one person will remain unincorporated to avoid corporation tax.
There are special laws on so-called "closely held" corporations. Those address some of these issues. If there were no corporation tax then they would be more important.
My description here tilted towards the UK & Irish situation because that's the one I understand the best. The short answer is…. If corporation tax were removed then the rules on many other taxes would have to be very carefully thought through and implemented. If they were not then it would open up the way for a lot of perfectly legal tax-avoidance.
Some people propose a policy similar to that in Estonia, where only dividends are taxed (20% in the aforementioned case). It's a clever proposal, but it doesn't alleviate the issue of self-incorporation. It does however at least hit the people raking in the most cash. Couldn't it just cause businesses to hoard money however?
I was personally thinking about taxing revenue at e.g 5% instead of a higher tax on profits. As I understand, this will hit supermarkets and other higher-turnover (did I use that term correctly?) businesses. This will shift costs to consumers. I don't think is is necessarily a terrible idea however, as being able to hit tech-giants and other big business with a 5% tax will produce more than enough revenue to implement stuff like UBI/NIT/other dividends to boost consumer purchasing power.
So yeah, is abolishing corporate taxes (on profits) a good way to go? What are the alternatives? Would taxing dividends/revenue be a viable alternative?
