Slovenia's statistics office revised upwards on Friday the troubled eurozone country's 2012 public deficit to 4.0 percent of economic output from a preliminary estimate of 3.7 percent.
The change was due to lower-than-expected corporate tax income, the statistics office said, adding that its 2013 forecast remained at 4.2 percent of gross domestic product (GDP).
Two-million-strong Slovenia, once a model EU newcomer, is seen in the next in line for a possible bailout due to major problems with its banks and a recession.
The European Commission has estimated Slovenia's public deficit in 2012 was 4.4 percent of GDP and predicted a 5.1 percent shortfall for this year.
Eurozone countries are obliged to keep their public deficits below three percent of GDP.
