The Eurozone sovereign debt crisis has highlighted the problem of tax evasion. This column examines the effect of social norms on tax compliance using the UK poll tax as a natural experiment. Comparing councils where tax evasion spiked more during the poll-tax period to those where it spiked less, there was no systematic difference before the poll-tax period. However, once the poll tax was abolished, tax evasion remained higher in the former group, suggesting that high poll-tax non-compliance created a persistent norm of non-compliance.

Recent experience with the zero lower bound on nominal interest rates, and the use of high-denomination notes by criminals and tax evaders, have led to revived proposals to phase out cash. This column argues that abolishing cash may be neither necessary nor sufficient to overcome the zero lower bound problem, and would severely undermine privacy. Allowing the public to hold reserves at central banks could reduce the need for deposit insurance, although the transition to the new regime and the effects on credit supply must be carefully considered.

Greece is currently implementing a fiscal adjustment programme aimed at tackling tax evasion. This column discusses the impact of recent tax administration reforms on tax compliance in Greece. The intensification of audits, enforcement of penalties, and efficient collection of past debts can induce tax compliance and raise the collected revenue. These findings could contribute to the successful conclusion of the fiscal consolidation programme.

Despite the growth of online and card payments, the ratio of currency to GDP in the UK has been rising. This column argues that rapid growth in the grey economy has been a key cause. The authors estimate that the grey economy in the UK could have expanded by around 3% of UK GDP since the beginning of the Global Crisis.

Greece’s austerity package included an unprecedented increase in the VAT rate, but the resulting increase in revenue was much lower than expected. This column links this disappointing result to the ‘transparency response’ of firms to higher tax rates. In countries like Greece with poor tax monitoring, firms face a tradeoff when deciding whether to declare their activity. Transparency is a necessary condition for accessing external finance, but it also means having to pay tax. Improving credit conditions for small and medium-size Greek firms might shift this tradeoff in favour of transparency.

Tax evasion and noncompliance reduce government revenue and exacerbate the problem of increasing debt. Standard economic theory predicts that the identity of the tax remitter shouldn’t affect outcomes – but this ignores the possibility of evasion. This column provides evidence that in the presence of evasion, both the amount of revenue collected and the incidence of burden are sensitive to the identity of the remitter. These results should inform future tax reform.

The countries most affected by the Eurozone debt crisis seem also to be characterised by bad institutions and large shadow economies. This column describes the bad equilibrium in which bad governments offer few and low-quality public services and make people less willing to pay for services. Firms stay underground, public receipts stay low, and governments remain inefficient. In sum, the presence of inept bureaucracy may be strongly associated with the shadow economy.

Can financial sector reform help bring informal firms into the formal sector? This column examines over 22,000 firms from 43 countries. Firms in countries with a credit registry are 20% less likely to evade taxes, and the tax evasion ratio in such countries is 11% lower.

Europe’s highly indebted countries – Portugal, Italy, Ireland, Greece, and Spain – also face the problem of tax evasion. This column analyses how governments can tackle their fiscal deficits while reducing the possibility of forcing activity underground. It suggests that fewer, better paid public workers could complement tax cuts in fighting tax evasion.

Russia’s economic and fiscal successes since adopting a flat tax in 2001 have bred enthusiasm for tax reform amongst casual observers. This column summarises research investigating the flat tax’s effects and suggests that many of the gains came from reduced tax evasion in Russia.
