I have already mentioned the demand made by 17 NGOs today for a Tax Dodging Bill.

How the Tax Dodging Bill website is live so I can link to the actual demand. In its briefing the campaign says:

It's time for bolder and broader action against tax dodging. All political
parties can demonstrate stronger commitment to tackling these issues,
by pledging to introduce a Tax Dodging Bill in the first hundred days after
the 2015 General Election. This Tax Dodging Bill should:

1. Make it harder for big companies to dodge UK taxes and make
sure they are not getting unjustified tax breaks by:


a) Ensuring that foreign multinationals can't use tax havens to avoid their
fair share of tax in the UK;

b) Rigorously reviewing tax breaks, ensuring that the full costs and
benefits of all tax breaks for companies are properly reported and
scrapping any which cannot be justified by their benefits to the
economy, society and the environment.


2. Ensure UK tax rules don't incentivise UK companies to avoid
tax in developing countries:

a) Toughening up the UK's anti-tax haven rules to deter tax dodging at
home and abroad and reviewing other tax rules to assess whether they
undermine developing countries' ability to raise vital revenue through
taxation.

3. Make the UK tax regime more transparent and tougher on tax
dodging, by:

a) Requiring companies to publish their taxes, profits and other key data
for each country where they do business;

b) Toughening the tax regime, making tax avoidance schemes riskier
for those promoting and benefiting from them and more costly when
they fail as well as ensuring that HMRC has the means to crack down
harder on tax dodging.

I admit I would not have written the demands like that: maybe these campaigners are more media savvy than me. But for those who want more detail that's available here.

And if you want to support the campaign, that's possible here.
