2017 Cost of Living and Inflation Adjustments

The Internal Revenue Service has announced new additions to the cost of living and inflation rate increases for several tax-related attributes for the 2017 year. The following summarizes adjustments announced to date.

  • The maximum amount of earnings subject to the Social Security tax will increase to $127,200.
  • The earnings limit for workers who are younger than full retirement age (age 66 for people born in 1943 through 1954) will increase to $16,920.
  • The earnings limit for people turning 66 in 2017 will increase to $44,880.
  • The amounts that can be deducted by businesses under Section 179 will increase from $500,000 to $510,000. The limitation on Section 179 eligible property placed in service during the tax year will increase from $2,010,000 to $2,030,000.
  • The generation-skipping tax exception and lifetime estate and gift tax exclusion have increased from $5,450,000 to $5,490,000 for the estates of decedents who die during 2017.
  • The amount of unearned net income that a child can earn without paying any federal income tax is $1,050. All unearned income in excess of $2,100 is taxed at the parent’s tax rate.
  • A number of tax items are unchanged in 2017, since the threshold only changes if the inflation adjustment increase is greater than $1,000. As a result, the personal exemption stays at $4,050; the ceiling on 401(k) retirement account contributions remain at $18,000; and annual gift tax exclusions are $14,000. Employer-provided fringe benefits for parking and transit remain at the 2016 amount of $255.

The following are additional items that have been adjusted for 2017:
