Employer contributions for employee pension and insurance funds increased $3.2 billion in January, compared with an increase of $3 billion in December, according to the Bureau of Economic Analysis. Employer contributions for government social insurance increased $2.7 billion in January, compared to $3.7 billion in December.

The January estimate reflected increases in the social security taxable wage base (from $100,000 to $113,700), in the tax rate paid by employers to state unemployment insurance, and in employer contributions for the federal unemployment tax and for pension guaranty. These changes added $5.9 billion to January.

Contributions for government social insurance — a subtraction in calculating personal income — increased $126.7 billion in January, compared with an increase of $6.3 billion in December.  The January estimate reflected increases in both employer and employee contributions for government social insurance.  The January estimate of employee contributions for government social insurance reflected the expiration of the "payroll tax holiday," that increased the social security contribution rate for employees and self-employed workers by 2 percentage points, or $114.1 billion at an annual rate.
