(Adds background on tax overhaul, details on Goldman earnings reduction)
Dec 29 (Reuters) - Goldman Sachs Group Inc said on Friday it expects fourth-quarter earnings to decrease by about $5 billion due to the new U.S. tax law signed by President Donald Trump last week.
Around two-thirds of the $5 billion decrease is due to repatriation tax, Goldman said in a statement with the U.S. Securities and Exchange Commission. (http://bit.ly/2C8j4br)
However, the impact of the tax legislation may differ from the estimate, according to the bank.
Congress last week approved a U.S. tax overhaul, the biggest in 30 years, which includes steep tax cuts for corporations and wealthy taxpayers.
The new law significantly lowers the income tax rate for U.S. companies - to 21 percent from 35 percent - allowing them to repatriate cash from overseas, and modifies numerous deductions, among other changes.
The tax overhaul will allow Apple Inc to bring back its $252.3 billion foreign cash pile without a major tax hit - a long-standing company goal.
Drugmaker Amgen Inc last Friday also said it expects to incur tax expenses of $6 billion to $6.5 billion over time as it repatriates cash it has accumulated around the world because of the new law. (Reporting By Aparajita Saxena in Bengaluru; Editing by Shounak Dasgupta)
