PRAGUE, Feb 17 (Reuters) - Czech centre-right coalition parties reached agreement on Thursday on the outline of pension reform, a major part of the cabinet's legislative agenda that will bring higher taxes and private savings to balance the system.
The Labour Ministry said a final draft of the plan will be submitted to the government at its next meeting on Feb. 23.
The Czech Republic has a relatively strong fiscal position thanks to a healthy banking sector not requiring any bailouts after the financial crisis, but demographic trends make the country's fiscal position unsustainable in the long run.
Rating agencies have said successful reforms of the pension, health and social systems could lead to an upgrade in sovereign ratings, now at 'A' by Standard and Poor's and 'A1' by Moody's.
The three governing coalition parties agreed on Thursday on creation of a voluntary opt-out from the pay-as-you-go system for people under 35, the ministry said in a statement.
Those older than 35 will have until the end of 2012 to decide on joining the opt-out.
The parties plan to unify value-added tax at the upper rate of 20 percent to cover the gap caused by the opt-out. Several food items will be kept at the lower level of 10 percent.
The main part of the reform is that the current pay-as-you-go system, in which social tax collected from working people is distributed to current pensioners, will be complemented by a stronger private-savings component.
Working-age people will be able to divert 3 percentage points from their social tax, at 28 percent, which will go to their own individual savings accounts, matched by at least a 2 percent contribution from their salaries.
Finance Minister Miroslav Kalousek told Reuters the plans for the opt-out would cost the state 20 billion crowns ($1.12 billion) a year once the reform is in place by 2013.
The VAT unification, which could start as early as next year, would bring 58 billion crowns in revenue per year, Labour Minister Jaromir Drabek said.
"(The changes) will be neutral in terms of the budget," he said. "We count on income from state-controlled companies, which will cover part of the current pension system deficit."
The agreement on a voluntary opt-out is milder than original calls for a compulsory switch. <^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ For FACTBOX on planned reforms, click on [

To the north, Poland is also planning to roll back some of its landmark pension reforms by reducing the contributions that flow into private accounts so it can raise budget revenues.
Analysts have called for Czech pension system reform for over a decade to counter the effects of population ageing.
The Czech pay-as-you-go system showed a 29 billion crowns ($1.62 billion) deficit in 2010, about 0.8 percent of gross domestic product, and the diversion of part of the 28 percent social tax into savings funds will create a wider gap.
Government studies have predicted the system would eventually generate deficits growing to around 4 percent of GDP every year without reform.
Drabek estimated that unifying VAT at the upper rate would not raise inflation by more than 3 percentage points. The central bank ignores the primary impact of indirect tax changes on prices from policymaking, but watches potential spillover into other prices.
