 Softbank CEO Masayoshi Son will announce a $100 billion investment in the U.S. over the next four years during a Monday visit to President-elect Donald Trump’s residence Mar-a-Lago in Palm Beach, Florida, sources familiar with the matter told CNBC’s Sara Eisen.

The billionaire investor and founder of the Japanese tech-investing firm will also promise in the joint announcement with Trump to create 100,000 jobs focused on artificial intelligence and related infrastructure, the sources said. The money will be deployed before the end of Trump’s term.

The funding could come from various sources controlled by Softbank, including the Vision Fund, capital projects or chipmaker Arm Holdings

, where the firm is majority owner. Some of the money will not necessarily be newly raised, but could include some funding already announced such as Softbank’s recent $1.5 billion investment in OpenAI, the tech firm behind chatbot ChatGPT.

Softbank’s Son and Trump made a similar announcement in 2016 after Trump was elected president for the first time, with the Japanese firm agreeing to invest $50 billion in the U.S. with the aim to create 50,000 jobs.

 With January just weeks away and inflation still impacting the wallets of Americans, taxpayers across the country are preparing to file in 2025.

To ease the transition, the Internal Revenue Service announces inflation adjustments each year, noting adjustments for more than 60 tax provisions. 

The IRS released numbers for tax year 2024 last year, nudging most taxpayers to pay close attention to the standard deduction for single and married filers.

For single taxpayers and married individuals filing separately, the standard deduction rose to $14,600, up $750 from tax year 2023, the IRS reported. For married couples filing jointly for tax year 2024, the deduction increased to $29,200, up $1,500 from tax year 2023, the IRS said. The IRS noted that for the head of household, the standard deduction went up $1,100, totaling to $21,900.

IRS tax rates for tax year 2024

The IRS announced tax rates for its seven tax brackets for tax year 2024:

• 37% – Single income over $609,350 and married couples filing jointly with income over $731,200
• 35% – Single income over $243,725 and married couples filing jointly with income over $487,450

Tax exemptions and credits

One change noted by the IRS relates to the alternative minimum tax exemption (AMT). Some tax benefits can significantly shrink a taxpayer's regular tax amount. The AMT is applied to high-income taxpayers by limiting these benefits, ensuring that these high-income taxpayers pay at least a minimum amount of tax, the IRS said on its website.

The AMT exemption amount for tax year 2024 increased to $85,700 and starts to phase out at $609,350, up $4,400 and $31,200 compared to tax year 2023, respectively. The exemption amount for married couples filing jointly increased to $133,300 and begins to phase out at $1,218,700, up $6,800 and $62,400 compared to tax year 2023, the IRS said.

The tax year 2024 maximum Earned Income Tax Credit amount for taxpayers with three or more qualifying children is $7,830, an increase of $400 from tax year 2023.

A spokesperson from the IRS said that based on public statistics, out of 153.8 million tax returns, fewer than 180,000 taxpayers paid the alternative minimum tax in 2023. Numbers may be higher, though since the numbers were only crunched through November.

Family coverage for tax year 2024 includes an out-of-pocket expense limit of $10,200 (an increase of $550 from tax year 2023).
