The Greek government continues to face pressure from the International Monetary Fund (IMF) to lower its annual tax-free threshold, which would force up to 1.5 million more people, including low-wage earners and lower-income pensioners, to enter the tax base.

As Greece looks to continue in its bailout program, the IMF is demanding that the country lower its tax-free threshold, which is one of the narrowest in Europe. The IMF has tied its future participation in the Greek bailout program to the lower tax-free threshold, a demand the country’s government has consistently pushed back against and would likely be reluctant to legislate in Parliament, where the current leftist government has only a narrow majority.

Greece’s current tax-free threshold sits at $9,203.04, although with in some tax-free categories it reaches $10,171.72. Additionally, tax revenue in the country is affected by tax evasion by some self-employed professionals and craftsmen. These factors have had a limiting affect on tax revenue in Greece, giving the country small yields in comparison to other European countries.

The IMF recently proposed lowering the tax-free threshold to rest somewhere between $6,393.96 and $7,992.45. Face-to-face negotiations between Greece and creditors have not yet begun again, and any changes put into effect would not apply until after 2018.
