Capital gains tax discourages investment and innovation. Income tax discourages work. Pick your poison.
You can raise some tax revenue by shifting the tax burden to 'bad' things instead of 'good' things - pollution, congestion, unhealthy foods, etc. But you can only go so far with these (at some point Pigouvian taxes start to become too successful...) and even then a lot of people flip out at having to pay fuel duty, congestion charges, etc.
I mean, we do need to raise taxes somehow. It turns out voters expect quite a bit from the state.
No, it's primarily to fund spending. But as a rule of thumb, once you've decided how much you'd like the state to spend on things, it makes sense to raise that amount of tax in the way that does the least harm.
Yes tax is a disincentive in as much as it raises cost, but we are no where near the limits any maximial analysis has indicated.
Also, given that losses can be offset, and structures like limited liability, mean that the financial risk to starting businesses are so small as to be almost non-existent. Literally £1.
So yes, there are limits which tax does cause meaningful disencentives, but we aren't close to those.
The problem with sin tax is that they just demonize a new behavior or product whenever they want to raise taxes. It becomes a financial burden to be yourself, depending on the whims of society.
No. Pigouvian taxes are about putting a price on the social cost of antisocial activities - pollution, congestion, etc.
If I close and seal all my doors and windows and then choose to pump CO2 and other harmful gases into my house, the cost of doing this is largely going to fall on me, and I can probably be trusted to be sensible about how much of this I do. But in the real world, there is no natural mechanism to force me to internalise the costs to the rest of you of pumping out carbon emissions into the atmosphere.
It's nothing to do with 'sin'. Pigouvian taxes are about putting the societal price on antisocial behaviour so market forces can function.
The problem is that they change the topics to tax more behaviors. It starts out as a carbon tax on big trucks, then they add a tobacco tax, then a vape tax, then an alcohol tax, then a bar tax, then a restaurant tax, then a soda tax, then a streaming video tax... Whenever they want more money they demonize a new behavior.
I'm an accountant and have clients regularly ask me how much tax they would have to pay for a certain investment before they make a decision. It absolutely dissuades some people.
Absolutely, a change to CGT may affect the risk-return profile of individual investments and might make some unpalatable. But it wouldn’t slow or stop investing altogether. One thing that has a bigger effect would be how much spare money people have to invest, how much they earn above their costs of living.
People have a financial incentive to invest their money somewhere (stock market, bonds, businesses, property, interest-bearing bank account) because if they don’t, their money devalues. Economically speaking it doesn’t matter so much where, so long as money cycles
around the country and doesn’t sit doing nothing - or leave (which is another issue with global investments). A change in CGT would have to be hugely disruptive to change that incentive.
This is pretty basic economics. Supply curves slope upwards - the higher the price people are offered for something, the more it people are willing to supply. It's exceptionally intuitive but there's reams of empirical evidence to support it if the concept isn't obvious enough to you.
To start with I think we need to stop giving credence to bunkum theories that state that people are free to provide or withhold their services as they see fit. It’s not the case for the majority of people.
Most people cannot afford not to work, they have no choice until they are financially secure enough, which few are. Either that or they physically can’t work, but in most cases they MUST work to pay rent, eat, survive. Even if you’re specialised in any job, when unemployed it’s only a matter of weeks before you need to pick any job, whatever you can get. Raising or lowering income tax will not affect that, only the amount of money you have when employed.
Even if you don’t HAVE to work, the financial incentive is always to work, because it gets you more money, which is the promise of a better time. Changing income tax doesn’t affect that either, just the rate at which you accumulate wealth, but if you don’t have to work at least you have a choice not to.
What affects employment more than income tax? Employment taxes. Because a business finding it cheaper to employ more staff… employs more staff. That financial incentive again, and a completely different set of levers. You can increase income tax and decrease employment tax, or both together, whatever. Independent.
You know what else can take people out of the workforce? Reducing CGT. It allows people to retire earlier or live off their investments. Changes the threshold of where your financial incentive to work balances your body’s ability to can. Whether that’s good or bad depends on your point of view.
On the subject of CGT, again, look at where the financial incentive lies. At what CGT threshold does it become more profitable not to invest in some vehicle, even risk-free-rate bonds, rather than stuffing a mattress? CGT only affects realisation of assets, so with a rate increase you would expect an increase in longer term investments, you might see people delaying retirement. It’s unlikely to affect actual investment, really only the amount of ready cash people have affects that. Lower income tax/higher CGT may actually increase investment in that case (though it’ll probably be mostly invested in other countries through SP500 or global trackers, so maybe not a good thing for the country).
