Payments of the national pension are uniform for everyone. To this amount were added the assistance payment, which varied according to a pensioner's marital status, the cost of living in his or her locality, and other pensions that he or she received. Other supplementary payments could be made for dependent children, for degree of disability, and for housing costs, as well as for veterans of the Civil War and of World War II. National pensions are indexed, and they increase in value each year. Since reforms of the early 1980s, national pensions became non-taxable if they were the sole source of income. Pensions were no longer affected by a spouse's earnings or pension income, and the national pension could only be reduced by income from other pensions. The National Pension Plan was funded by the beneficiary's own contributions, about 2 percent of his or her locally taxable income, and by employer contributions of 4 to 5 percent of the insured person's wages.
