PRAGUE, Jan 21 (Reuters) - The main Czech leftist party which leads opinion polls ahead of an election in May plans to hike taxes to plug budget holes, it said in an economic programme revealed on Thursday.
Social Democrat chief Jiri Paroubek said he saw euro adoption in 2014-2015, which analysts said was a highly optimistic date given deep budget gaps and the lengthy euro entry procedure.
The latest opinion poll released on Monday showed the leftists had 28.7 percent support, 8.6 percentage points ahead of the Civic Democrats. No party is however expected to win a majority and the winner will need to seek coalition partners. [
]The Czech fiscal gap soared to nearly 7 percent of gross domestic product last year as the economy shrank by over 4 percent, even though the country, rated 'A' by Standard and Poor's, was not forced to bail out any banks and avoided a debt meltdown seen in regional peer Hungary.
This year's budget sees a deficit of around 5.3-5.7 percent and the country's interim government says fiscal consolidation aimed at preventing a fast debt growth from the current 40 percent of GDP required reforms of the welfare and pension systems.
"In order to keep our good sovereign rating... it is enough to continue with the fiscal consolidation already started," Paroubek told a party conference.
"Different goals could threaten the revival of economic growth and social cohesion in the country. We will see to it that the burden is not placed on the employees, while the 5 percent of the richest enjoy lower taxes."
The party said it would hike personal, corporate and excise taxes to raise 35-45 billion crowns ($1.92-2.47 billion) per year, and also raise dividends paid by majority state-owned power firm CEZ <
> by 10 billion crowns.It aims to achieve savings through an audit of state spending, cutting corruption and clamping down on tax evasion. The plan calls for a hike in the corporate tax rate to 21 percent from 19 percent, and for instituting a new 38 percent tax bracket on personal income over 1.2 million crowns per year.
Analysts cast doubt on the plans, saying they may not be realistic.
Pavel Sobisek, chief analyst at UniCredit in Prague, said he was surprised by the lack of cuts on the expenditure side.
"I would conservatively divide the contribution from higher taxes by two. When I compare that with additional costs of social transfers, the net impact is close to zero," he said.
"It does not seem that it would be possible to lower the fiscal deficit below 3 percent on the basis of the proposed measures."
Sobisek also pointed out that the party planned cutting the budget gap below the euro-entry limit of 3 percent by 2014 and join already by 2015.
That would however be hardly possible, given the need for an assessment by the euro zone countries. Narrowing the gap in 2014 would allow euro entry in 2016 at the earliest, he said.
The party has been building its lead over the main right-wing party, the Civic Democrats, who are more in favour of spending cuts, but less keen on euro adoption. (Writing by Jan Lopatka; editing by Ron Askew)
