Circular 01/2009/TT-BLDTBXH on adjustment rates for wages already paid into social insurance for workers under employer-decided wage regimes per Clause 2 Article 5 of Decree 83/2008/ND-CP of July 31, 2008

Circular 01/2009/TT-BLDTBXH, issued by the Ministry of Labour, Invalids and Social Affairs on 14 January 2009, sets the adjustment coefficients for wages and earnings already used as the social insurance contribution base, for workers under the employer-decided pay scheme, implementing Decree 83/2008/ND-CP. The adjustment, often called wage indexation, applies to workers currently participating in or preserving their social insurance period who, from 1 January 2009 onward, draw a pension, a one-time allowance on retirement, a one-time social insurance payment, or whose survivors receive a one-time death benefit, and who have contribution time under the employer-decided pay scheme. The mechanism revalues past contributions to current values using coefficients derived from the average annual consumer price index under Article 3 of Decree 83/2008/ND-CP. The Circular provides a single table of multipliers by contribution year, applicable to those whose benefit is settled between 1 January and 31 December 2009: pre-1995 contributions are multiplied by 2.54, then 1995 by 2.16, 1996 by 2.04, 1997 by 1.97, 1998 by 1.83, 1999 by 1.76, 2000 by 1.78, 2001 by 1.79, 2002 by 1.72, 2003 by 1.67, 2004 by 1.55, 2005 by 1.43, 2006 by 1.33, 2007 by 1.23, and 2008 and 2009 by 1.00. The adjustment formula is straightforward: the adjusted monthly contribution wage for each year equals the total monthly contribution wage under the employer-decided pay scheme for that year multiplied by the coefficient for the corresponding year. The revalued amounts then feed the average monthly contribution wage that serves as the basis for computing pensions, one-time retirement allowances, one-time social insurance payments, and one-time survivor benefits, calculated under Article 31 of Decree 152/2006/ND-CP and Article 34 of Decree 68/2007/ND-CP, with the employer-scheme portion indexed as set out here. The Circular takes effect 45 days after signing, with the provisions applied from 1 January 2009. These coefficients are directly relevant to pension and social-insurance benefit calculations, since they convert historical contribution wages into present terms before averaging. The table is reissued annually with updated values to reflect inflation, so the 2009 coefficients apply only to benefits settled during that calendar year. The Ministry invites feedback on implementation difficulties for timely resolution.
