The campaign organisation UK Uncut says that planned protests outside 40 Starbucks stores will take place this weekend, despite the organisation offering to pay £10 million pounds in corporation tax.
Spokeswoman Hannah Pearce said that offering to pay some tax "if and when it suits" did not stop the company being a tax avoider.
"Today's announcement is just a desperate attempt to deflect public pressure" she continued.
"There is no money yet, and hollow promises on press releases don't fund women's refuges or child benefits."
Amazon pays all applicable taxes in every jurisdiction that it operates within. Amazon EU serves tens of millions of customers and sellers throughout Europe from multiple consumer websites in a number of languages dispatching products to all 27 countries in the EU. We have a single European Headquarters in Luxembourg with hundreds of employees to manage this complex operation.
Today, I am announcing changes which will result in Starbucks paying higher corporation tax in the UK - above what is currently required by law. Specifically, in 2013 and 2014 Starbucks will not claim tax deductions for royalties or payments related to our intercompany charges.
In addition, we are making a commitment that we will propose to pay a significant amount of corporation tax during 2013 and 2014 regardless of whether our company is profitable during these years.
We are still working through some of the calculations, but we believe we could pay or prepay somewhere in the range of £10m in each of the next two years in addition to the variety of taxes we already pay.
Doing the right thing is part of the DNA of our company (and of the thousands of people who work here that we call “partners,” because each of them have equity in the form of shares in our company) and over these past 14 years we’ve been doing business here in the UK, the most important asset we have built and developed with our customers is trust.
The owner of a solitary food store told ITV News he was "angry" that he paid more corporation tax than Starbucks.
His comments came after the Chancellor unveiled a £154 million blitz on big-name global companies and wealthy individuals who dodge tax bills to claw back billions of pounds for the Treasury.
ITV News deputy political editor Chris Ship reports:
Asked about tax avoidance on ITV1's Agenda, Foreign Secretary William Hague said international agreements are needed to tackle the issue.
He said: "This really needs international agreement to really sort out the international company moving its profits from one country to another. You need international rules and George Osborne and the German finance minister are leading the way on this to get those international rules agreed...
"In the meantime, we've got the increased tax avoidance measures and this great thing of public pressure that you can feel whether from the audience tonight or the Public Accounts Committee.
"It will affect the sales of Amazon, Starbucks and whatever so some of them are feeling they have to do something about it anyway and that is a big improvement."

It is very frustrating for many companies who pay large tax bills that some multinationals are able to avoid doing so.
The solution must be simplifying the tax system, not simply hectoring from Westminster. If these firms are immoral to take advantage of tax loopholes, then politicians are surely immoral for creating the loopholes in the first place.
Taxes should be simpler to cut down on avoidance and relieve the burden our complex tax code puts on companies who do try to do the right thing.
The Chancellor vows to crackdown on big-name global companies and wealthy individuals who dodge tax bills in a bid to claw back billions of pounds for the Treasury.
Political Correspondent Libby Wiener reports:
The Treasury has announced it will provide the HMRC with £77 million of new funding in this Spending Review period in a bid to clamp down on tax dodgers.
It is hoped the funding will help target offshore evasion and avoidance by wealthy individuals and by multinationals.
Asked whether David Cameron would back calls for a consumer boycott of firms which avoid tax, the Prime Minister's official spokesman told a regular Westminster media briefing:
The issue for Government is how we tackle that tax avoidance, and the Treasury have been setting out what we intend to do today.
What we have to do in Government is make sure we are tackling that kind of aggressive tax avoidance. We are doing that in a number of ways. We are bringing in a general anti-avoidance rule, we are working with other countries.
The question of a boycott was "an issue for individuals", the spokesman said.
Clearly, we think that all companies should make a fair contribution to taxes and clearly that's a view that is shared by taxpayers and consumers.
HMRC ensures that multinationals pay the tax due in accordance with UK tax law.
We have been very successful in reducing tax avoidance by large businesses in recent years.
We relentlessly challenge those that persist in avoiding tax and have recovered £29bn additional revenues from large businesses in the last six years, including £4.1bn in the last four years from transfer pricing enquiries alone.
These figures speak for themselves.
Corporation tax receipts are dependent on the wider economy and the corporation tax rate set by Parliament, which was reduced by 2 percentage points for 2011-12.
