Changing several social benefits from net sum into gross sum (taxable) in connection with the tax reform of 1st January 1994 has caused minor breaks in the time series from 1993 to 1994. The tax reform particularly affects the level of social pensions to singles, where the total amount paid out was raised and personal income tax deductions was reduced. At the same time, a range of tax-free transfers was raised and made subject for taxation, for example supplements to social pensions and cash benefits.

a-Income statistics are not published independently in a final version, but is included in the formation of the final Personal Income Statistics. The difference between the preliminary a-income statistics and the a-incomes used in the final register is usually between 0.0 and 0.3 per cent.

The a-income population is individuals who are at least 15 years at the end of the year and has been in Denmark throughout the year. Personal Income Statistics has the additional requirement that a person is fully liable to taxation. This results in a difference of population of 10-15 thousand people, representing a deviation of 0.2 to 0.3 per cent. Many of these people have no reported income in Denmark.
