Families headed by salaried workers will lose as much as ¥600,000 in take-home income in 2013, when the government raises taxes to fund disaster reconstruction and hikes pension premiums, estimates by a private research agency show.
A family with a gross annual income of ¥4 million will see ¥132,900 less in take-home income, the Daiwa Institute of Research said.
But a family that is generating an income of ¥8 million a year will receive ¥151,500 less.
Meanwhile, families with an income of ¥10 million could see take-home pay fall by ¥407,700 per year, while a family earning ¥20 million will get ¥601,100 less, the institute said.
In addition to tax hikes and pension charges, the calculation includes reductions in child allowances being given to families with a wage earner, spouse and two elementary-school-aged children.
But the drop will be bigger for wealthier households, especially because those who make more than ¥9.6 million a year will not be eligible for child allowances starting in June 2012.
The calculations, however, do account for a possible jump in the consumption tax, which is being discussed as part of integrated reforms to the tax and social security systems.
According to separate projections worked out by Dai-ichi Life Research Institute, should the consumption tax be hiked to 8 percent from the current 5 percent, a family of four with two children and an annual income of ¥4 million would pay about ¥71,000 more per year in taxes alone, and a similar household earning ¥8 million would have to shell out an additional ¥117,000.
