Tax Filing Season Is Underway: Here's How It's Going So Far

There are about five weeks left in tax filing season — the busiest time of year for the IRS and tax preparers. IRS CEO Frank Bisignano told lawmakers earlier this month the tax season has so far been a success, with quick refund turnaround times and a shrinking backlog. That is despite a tumultuous 2025 for the agency, when the IRS lost about a quarter of its workforce to resignation offers, began implementing the GOP's new tax-and-spending law, and managed the fallout of the longest government shutdown in US history. Tom O'Saben, director of tax content and government relations at the National Association of Tax Professionals, said tax preparers also aren't hearing a ton of complaints from clients either. On this episode of Talking Tax, O'Saben joined Bloomberg Tax reporter Erin Slowey to discuss how filing season is going, the impact of changes from the 2025 law, and what to do if you don't have the money to pay taxes by the deadline. "Don't put your head in the sand and say 'I know I am going to owe so I am just not going to file,'" O'Saben said. "That's a bad idea." Do you have feedback on this episode of Talking Tax?

Tax-filing season is well underway, and yet many states are still figuring out whether to conform to or decouple from provisions in last year's GOP-led tax overhaul, especially the deductions and other breaks for corporate taxpayers. The upshot is one of the more complicated filing periods in recent years. Corporate taxpayers are watching which states reject federal tax policy changes, such as those related to immediate expensing for research and development or property investments. Just in the past week, lawmakers in Republican-controlled states like Florida and Democrat-led states like Oregon moved ahead in decoupling from some of those corporate tax provisions to preserve billions of dollars in state revenue. Then there's the unique situation in Washington, DC, where a local law severing the city's tax code from more than a dozen provisions in the 2025 federal tax rewrite was met with Congress's formal disapproval. That set off a dispute between Capitol Hill and city leaders over whether the district's decoupling measure is in effect. (DC officials say it is.) Most of all, corporate taxpayers are looking for clarity from the states as they plan their filings, Scott Roberti, a managing director focusing on state and local tax in EY's national tax practice, says on this week's episode of Talking Tax. Roberti tells Bloomberg Tax editor Benjamin Freed that so far, at least 17 states have issued some sort of guidance on the conformity issue. Roberti hopes the remainder finish up soon in time for the end of filing season and quarter-end accounting. Do you have feedback on this episode of Talking Tax?

The Supreme Court's decision to nix a wide swath of the Trump administration's tariffs comes with some big tax and transfer pricing questions for tax executives as companies battle to collect refunds from the government. The court's 6-3 ruling sets up what would be a messy refund process, though the justices basically said nothing about it, leaving companies to take their claims to court. If the refunds come in, businesses will have to figure out how to apportion funds across subsidiaries —sometimes across borders — without breaking transfer pricing rules, which govern the pricing of affiliate transactions and ultimately determine where taxes are owed. The rules say related-party transfers must be priced as though they were done at arm’s length, in the open marketplace. Companies that don't do it right risk a tax agency audit. On this episode of Talking Tax, Bloomberg Tax transfer pricing reporter Caleb Harshberger discusses the sticky tax and transfer pricing issues surrounding tariffs and the possibility of refunds.

Tax enforcement has entered a new age. The decades-old Justice Department Tax Division is now split between the broader civil and criminal divisions. Critics say the reorganization sends a signal that tax enforcement won't be a priority. While the reorganization may mean tax attorneys are pulled into different DOJ priorities, it also could mean more investigations will include tax charges, said Karen Kelly, who was the top official at the DOJ Tax Division before she joined Kostelanetz as a partner in August. DOJ tax attorneys are prioritizing immigration, fraud, and investigations into tax-exempt organizations that may have ties to "Antifa," Kelly said. The latter refers to an informal collection of people with left-leaning views that was a focus of a recent directive from Attorney General Pam Bondi. On this episode of Talking Tax, Kelly sits down with Bloomberg Tax reporter Erin Schilling to discuss DOJ's tax enforcement priorities, changing strategies, and how taxpayers should prepare.

Data centers have emerged as a major political target in state capitals as they proliferate across the country and elected officials hear complaints from their voters about the massive, energy-guzzling warehouses. That has put tax breaks for data centers—which can amount to hundreds of millions of dollars annually in some states—squarely in the legislative cross hairs. State lawmakers in more than a dozen states have introduced legislation to repeal sales tax exemptions or raise the bar to qualify for them. Support for rolling back incentives cuts across party lines, with Republicans and Democrats expressing opposition to subsidizing a rapidly growing industry. But the industry's boosters also cross party lines, and two Republican governors have vetoed attempts in previous years to repeal the tax breaks. On this episode of Talking Tax, Bloomberg Tax reporter Daniel Moore discusses how these tax exemptions work, why they've grown so much, and how they could change this year.

A new slate of leaders is poised to make its mark on the US audit board and launch the next chapter for the embattled regulator. Among those set to serve on the Public Company Accounting Oversight Board are two administration officials who have held key roles at federal agencies targeted by a White House campaign to hobble federal agencies and derail regulations. Those agencies include the Consumer Financial Protection Bureau and the National Credit Union Administration. The PCAOB last year was also caught up in the administration’s efforts to rein in the federal bureaucracy. Republican lawmakers attempted to sunset the board and hand its duties over to the Securities and Exchange Commission, which oversees the board and named the new leaders. On this episode of Talking Tax, Senior Reporter Amanda Iacone discusses the incoming board members and what this latest leadership shake-up means for the future of the independent audit regulator.

Trump administration cuts to federal funding are trickling down to cities and states across the country—and a top public-sector accounting leader is taking note. Governmental Accounting Standards Board Chair Joel Black is leading his team in crafting public sector financial reporting rules at a time when local governments are assessing resource constraints following cuts to funding resulting from the 2025 GOP tax law. The board establishes financial reporting and accounting rules for state and local governments that follow generally accepted accounting principles, or GAAP. Municipal bond insurers, taxpayer groups, and research institutes are among those that use government financial reports to analyze fiscal health. The board's work during the height of the Covid-19 pandemic informs its efforts now during another period of strain for governments. "It really honed us in to be sure we're working on only those things that are significant improvements, only those things our stakeholders are really asking us to work on," Black said. Black's board is currently undertaking a project that aims to improve financial reporting rules for governments grappling with fears they won't be able to meet their financial obligations. In this week's Talking Tax, Black sat down with Bloomberg Tax reporter Jorja Siemons to discuss GASB's financial stress-related project and the resource challenges accounting teams are facing.

A global minimum tax deal that exempts American companies from key provisions is a better outcome for European business than the alternative of US retaliatory taxes, the co-chair of the OECD’s business committee said. The package agreed to this month by more than 145 countries at the Organization for Economic Cooperation and Development headed off a threat of steep US taxes on foreign companies if global concessions weren’t made. In this episode of Talking Tax, Christian Kaeser, global head of tax at Siemens AG, told Bloomberg Tax reporter Ryan Hogg that some of his European counterparts regarded the deal as “lopsided” but welcomed new permanent safe harbors that were created with input from Business at OECD, known as BIAC. Kaeser is co-chair of BIAC’s tax committee. “I’m pretty happy with the outcome,” he said. Competitive disparities created by the deal can be remedied by simplification of the EU’s own rules, including scrapping of the bloc’s controlled foreign companies anti-tax avoidance regime, he said. As for Pillar One, the other main part of a 2021 OECD-led tax agreement, Kaeser saw little hope. Further talks on the pillar, which would reallocate taxing rights to countries where big companies make their profits, have stalled for years. It “should be called Pillar Zed, zed for zombie,” he said. Do you have feedback on this episode of Talking Tax? Give us a call and leave a voicemail at 703-341-3690.

Republicans on Capitol Hill are keenly watching how other countries implement a long-sought OECD agreement that exempts US companies from parts of the global minimum tax framework. Rep. Ron Estes (R-Kan.), a member of the tax-writing House Ways and Means Committee, hasn't ruled out resurrecting legislation imposing retaliatory taxes on firms from nations that slow-walk codifying the deal. The deal was reached earlier this month after the Trump administration demanded a carve-out for American companies and for the US tax system to work alongside the global minimum tax framework without interference. Estes sat down with Bloomberg Tax Congress reporter Zach C. Cohen in his Capitol Hill office to talk about the importance of the agreement to American businesses and how he will "trust, but verify" other countries' tax code changes, especially if they pursue the same kind of exemption Washington just secured.

The OECD just published the parameters of a deal that would exempt US companies from two key enforcement rules in the global minimum tax framework. The deal, which spans 88 pages in the form of administrative guidance, includes a slew of safe harbor rules that address everything from how US companies can get the exemption to more advantageous treatment of substance-based tax incentives like the US R&D credit. It includes a permanent, simplified global minimum tax calculation. Other countries would be able to obtain carve-outs like the ones obtained by the US and its multinational companies—if they meet certain criteria. This week on Talking Tax, reporters Lauren Vella and Somesh Jha discuss why the deal and the timing of its release is important, what it means for multinational businesses, how key US lawmakers reacted, and what the deal means for the efficacy of the global minimum tax going forward.
