If you can’t file your taxes by the April 15 deadline, there’s a free, easy way to submit a federal tax extension online, experts say.  

Nearly 1 in 3 American admit that they procrastinate when it comes filing their taxes, according to a January survey of more than 1,000 U.S. filers from IPX1031, an investment property exchange service. In addition, about 25% do not feel prepared to file their taxes, the survey found.

As of March 21, the IRS received roughly 80 million individual returns of the 140 million expected this filing season, the agency’s latest reporting shows.

Many natural disaster victims have an automatic tax extension, which varies by jurisdiction. Military members serving in a combat zone also have more time to file. 

However, the federal tax deadline for the majority of taxpayers is April 15. It’s possible to push that due date to Oct. 15 by filing for an extension.

But “it’s an extension to file, not an extension to pay,” said Jo Anna Fellon, managing director at financial services firm CBIZ.

After the tax deadline, you will start incurring the failure-to-pay penalty of 0.5% of your unpaid taxes for each month or partial month that your taxes remain unpaid. The failure-to-pay penalty has a maximum charge of 25% of your unpaid taxes.

That’s cheaper than the failure-to-file penalty, which applies when you don’t submit your return by the deadline. The failure-to-file penalty is 5% of unpaid taxes monthly, also limited to 25%.

But you’ll also owe interest on your unpaid balance, which is currently 7% and accrues daily after April 15.

You can estimate your taxes owed by creating a “pro forma return” — or mock version of your filing — using as many tax forms as possible, Fellon said.

For federal taxes, you can complete Form 4868 and mail it to the IRS. But it’s better to file digitally to avoid processing delays amid the agency’s shrinking workforce, experts say. Paper filing can also increase fraud risk, they say.

The “easiest way” is by choosing “extension” when making a payment for 2024, which automatically submits Form 4868, according to Tommy Lucas, a certified financial planner and enrolled agent at Moisand Fitzgerald Tamayo in Orlando, Florida.

“It takes all of five minutes,” and you can double-check the transaction via your IRS online account, he said.

Alternatively, you can file your extension for free online via IRS Free File, a public-private partnership between the IRS and several tax software companies.   

For the 2025 season, you can use IRS Free File for returns if your adjusted gross income, or AGI, was $84,000 or less in 2024. But there’s no income limit to file an extension, Lucas said.

The Trump administration’s appeal of a temporary restraining order blocking the so-called Department of Government Efficiency from accessing sensitive personal Social Security Administration data has been dismissed.

The U.S. Court of Appeals for the 4th Circuit on Tuesday dismissed the government’s appeal for lack of jurisdiction. The case will proceed in the district court. A motion for a preliminary injunction will be filed later this week, according to national legal organization Democracy Forward.

The temporary restraining order was issued on March 20 by federal Judge Ellen Lipton Hollander and blocks DOGE and related agents and employees from accessing agency systems that contain personally identifiable information.

That includes information such as Social Security numbers, medical provider information and treatment records, employer and employee payment records, employee earnings, addresses, bank records, and tax information.

DOGE team members were also ordered to delete all nonanonymized personally identifiable information in their possession.

The plaintiffs include unions and retiree advocacy groups, namely the American Federation of State, County and Municipal Employees, the Alliance for Retired Americans and the American Federation of Teachers. 

“We are pleased the 4th Circuit agreed to let this important case continue in district court,” Richard Fiesta, executive director of the Alliance for Retired Americans, said in a written statement. “Every American retiree must be able to trust that the Social Security Administration will protect their most sensitive and personal data from unwarranted disclosure.”

The Trump administration’s appeal ignored standard legal procedure, according to Democracy Forward. The administration’s efforts to halt the enforcement of the temporary restraining order have also been denied.

“The president will continue to seek all legal remedies available to ensure the will of the American people is executed,” Liz Huston, a White House spokesperson, said via email.

The Social Security Administration did not respond to a request from CNBC for comment.

Immediately after the March 20 temporary restraining order was put in place, Social Security Administration Acting Commissioner Lee Dudek said in press interviews that he may have to shut down the agency since it “applies to almost all SSA employees.”

Dudek was admonished by Hollander, who called that assertion “inaccurate” and said the court order “expressly applies only to SSA employees working on the DOGE agenda.”

Dudek then said that the “clarifying guidance” issued by the court meant he would not shut down the agency. “SSA employees and their work will continue under the [temporary restraining order],” Dudek said in a March 21 statement.

It may be time to rethink the traditional 60/40 investment portfolio, according to BlackRock CEO Larry Fink.

In a new letter to investors, Fink writes the traditional allocation comprised of 60% stocks and 40% bonds that dates back to the 1950s “may no longer fully represent true diversification.”

“The future standard portfolio may look more like 50/30/20 — stocks, bonds and private assets like real estate, infrastructure and private credit.” Fink writes.

Most professional investors love to talk their book, and Fink is no exception. BlackRock has pursued several recent acquisitions — Global Infrastructure Partners, Preqin and HPS Investment Partners — with the goal of helping to increase investors’ access to private markets.

The effort to make it easier to incorporate both public and private investments in a portfolio is analogous to index versus active investments in 2009, Fink said.

Those investment strategies that were then considered separately can now be blended easily at a low cost.

Fink hopes the same will eventually be said for public and private markets.

Yet shopping for private investments now can feel “a bit like buying a house in an unfamiliar neighborhood before Zillow existed, where finding accurate prices was difficult or impossible,” Fink writes.

After both stocks and bonds saw declines in 2022, some analysts declared the 60/40 portfolio strategy dead. In 2024, however, such a balanced portfolio would have provided a return of about 14%.

“If you want to keep things very simple, the 60/40 portfolio or a target date fund is a great starting point,” said Amy Arnott, portfolio strategist at Morningstar.

If you’re willing to add more complexity, you could consider smaller positions in other asset classes like commodities, private equity or private debt, she said.

However, a 20% allocation in private assets is on the aggressive side, Arnott said.

The total value of private assets globally is about $14.3 trillion, while the public markets are worth about $247 trillion, she said.

For investors who want to keep their asset allocations in line with the market value of various asset classes, that would imply a weighting of about 6% instead of 20%, Arnott said.

Yet a 50/30/20 portfolio is a lot closer to how institutional investors have been allocating their portfolios for years, said Michael Rosen, chief investment officer at Angeles Investments.

The 60/40 portfolio, which Rosen previously said reached its “expiration date,” hasn’t been used by his firm’s endowment and foundation clients for decades.

There’s a key reason why. Institutional investors need to guarantee a specific return, also while paying for expenses and beating inflation, Rosen said.

While a 50/30/20 allocation may help deliver “truly outsized returns” to the mass retail market, there’s also a “lot of baggage” that comes with that strategy, Rosen said.

There’s a lack of liquidity, which means those holdings aren’t as easily converted to cash, Rosen said.

What’s more, there’s generally a lack of transparency and significantly higher fees, he said.

Prospective investors should be prepared to commit for 10 years to private investments, Arnott said.

And they also need to be aware that measurement issues with asset classes like private equity means past performance data may not be as reliable, she said.

For the average person, the most likely path toward tapping into private equity will be part of a 401(k) plan, Arnott said. So far, not a lot of companies have added private equity to their 401(k) offerings, but that could change, she said.

“We will probably see more plan sponsors adding private equity options to their lineups going forward,” Arnott said.
