One tax hike I'll be hoping for in the Budget (and some cuts as well)

Back home in Ireland, it’s said that asking for directions will often get you the reply, “I wouldn’t start from here.” We might say the same thing about the UK’s tax code. Nobody drawing up a tax system for the country would create anything like what we have right now, and when it comes to reform – well, I wouldn’t start from here. One example, which I talked about on the Today Programme this morning, is VAT. VAT is usually considered to be one of the least bad taxes around: in theory, it doesn’t discourage production, it isn’t very regressive, and it doesn’t distort the economy.

I say “in theory” because in practice the UK’s VAT system is a mess. It is riddled with exemptions (I am including zero-rated and reduced-rated goods in this) that distort people’s spending, which means that resources are being wasted, because people are buying relatively more of the untaxed goods and less of the taxed ones than they would be if the playing field was level.

The usual argument for these exemptions is that they are needed to reduce the burden on the poor. This is a powerful argument but it is wrong.

Many of the exempted items are unlikely to benefit the poor anyway – financial services, the construction of new dwellings, domestic passenger transport – but even for things like children’s clothes and food the argument is wrong. Although poor people spend a greater fraction of their budgets on exempted items like these, total spending on these goods rises with income, so most of the forgone revenue is actually from the rich.

The extra money raised could easily offset the extra cost to the poor by reducing income taxes on them (including national insurance contributions) or by raising the Universal Credit payment level. We could actually offset the extra cost to almost everyone, but except for people on low pay I think there are better taxes we could cut with the money left over.

The IFS estimated in 2010 that scrapping all VAT exemptions would raise an extra £26-28bn, based on 2010-11 numbers. Conservatively, rounding that up to £30bn to account for the larger economy, and spending half on boosting the incomes of the poor, we have £15bn left to play with. We’ve suggested scrapping capital gains tax to boost investment and using the rest to reduce the deficit.

In simplifying VAT we can make one important tax much less destructive without hurting the poor and use the money left over to cut taxes that are even worse.

Politically, this might not deliver good headlines, but if it was done at the start of the next Parliament the boost to people’s living standards by the next election could, improbably, make raising taxes on food and children’s clothes a real winner.

We might not want to start from here to get our sensible tax system, but this is one reform that could be a good step in the right direction.

ASI's Budget 2015 wishlist: A tax code that actually makes sense

Nobody designing the UK’s tax code from scratch would come up with one like the system we have now. Our taxes are complicated and inefficient and divert capital away from productive investments that would boost economic growth. This year, we’re hoping for a Budget that reforms the tax code in line with the best economics out there, reforming the worst taxes and cutting the tax burden on investment and the working poor: VAT: broaden the base and use the money to help the poor

The huge number of exemptions to VAT make the tax so inefficient that if we raised the rate to 20% on every good we could compensate every household and still have a few billion pounds left over. If, instead, we raised every good to the 20% flat rate, but compensated only households earning less than median income, we'd have billions left over to reduce the deficit. The money raised should be given back to people on low pay through tax credits and to create a higher national insurance contributions threshold, which would increase the incentive to work on the other end.

Capital Gains Tax: abolish it outright to boost growth

Capital Gains Tax (CGT) is an extremely inefficient tax on capital that reduces overall investment and raises just £5bn annually. CGT reduces investment, 'locks-in' capital to less productive investments and can be avoided by not investing in assets that will rise in price, so it is distortionary and ends up directing investment away from riskier assets like start-up business debt. Scrapping CGT would not cost a lot (and could be paid for with the money left over from the VAT broadening, above), and would boost investment and growth, boosting wages across the board.

Business rates & council tax: revalue with a view to eventually merge

Business rates & council tax are in theory some of the least bad taxes on the books. As long as the values they are levied on are kept up-to-date, they reduce economic activity much less than most taxes. But in the modern world house prices and land prices move rapidly and not uniformly. The North is currently being hammered—paying business rates far higher than their property deserves—the South is winning out with unfairly cheap payments. Council tax is even worse: the band system is out-of-date and should be replaced with a fluid penny in the pound system like rates, while the revaluation long postponed from 1993 should be done now and then kept constantly up-to-date. If Zoopla can get good estimates of property values then surely HMT can too. Eventually the two systems should be merged at the same rate, so that housing and business both go where they are most in demand.
