Study finds the more efficient the AI, the more complex its implementation

Published

on

The efficient way for accounting firms to integrate generative AI into their workflow is through robotic process automation that interfaces directly with the model’s application programming interface, though this method also requires the most expertise to implement and maintain.

This is the conclusion of a recent paper published in the American Accounting Association’s Journal of Emerging Technologies in Accounting, authored by Rutgers University professors  Huaxia Li and Miklos A. Vasarhelyi. The paper presented a general analysis of how accounting firms deploy large language models (e.g. ChatGPT, Claude, Gemini, etc.), and the pros and cons of each approach. Overall, it appears that more complex tasks are best performed by more complex deployment methods, which tend to be more difficult to use. Conversely, simpler deployments are better suited to simpler tasks but are much less efficient.

The paper specifically named four different ways firms deploy generative AI. 

The most straightforward way to do so is through a user interface with visual and interactive elements–picture ChatGPT’s web interface as an example. The paper said this method is most accessible for accounting researchers and practitioners seeking to implement LLMs, as it simply requires an internet-connected computer. It is also the cheapest in terms of access cost. At the same time, it is the least scalable and customizable of all the options and the slowest as well due to token limitations. This in mind, the study’s authors said this method is best used for client engagement and consultation, basic financial analysis and reporting and basic compliance checking. 

The second is through connecting to the model directly via an API, a type of software interface enabling computer programs to communicate with each other, enabling direct passage of data. Firms can leverage an API to establish connections between their local applications/systems and the LLM service, enabling data interaction between them. This API approach can be integrated into existing workflows without significantly altering their structure, is well suited for scalable processing and allows for a greater degree of parameter setting and customization. At the same time, deployment is more complex, requiring skilled personnel to pull it off. Another limitation is the potential incompatibility of the existing workflow with API connections. The authors said some accounting tasks that benefit most from the API approach include basic financial data extraction, transaction classification and verification, and basic fraud detection. 

The third is using RPA to interact directly with a traditional user interface. This allows for batch querying that the user interface method alone cannot accommodate, and is easier to integrate than the API method alone as RPA can mimic human interactions and so even if the existing system does not support underlying programming-level interaction, RPA can still connect it with the model’s user interface to enable automatic querying. Additionally, the UI-RPA method can also be combined with manual efforts that require human judgment. However, the setup is even more complex than the API method alone, and the maintenance process will also require skilled personnel who can update the bots based on changes in the user interface and the working process. Further, not every system integrates with RPA, and introducing new software might create additional privacy and cybersecurity issues, especially for accounting tasks. The authors said UI-RPA is suitable for accounting tasks such as expense management and auditing, asset management and depreciation scheduling, and budgeting and forecasting that require interaction between LLM and local systems.

The fourth is using RPA to interact with the API connected to the large language model. This is the most in-depth integration a firm could have with existing workflows, and the paper said this method maximizes the efficiency of implementing LLMs in the accounting domain. It is more efficient than even the RPA to user interface method as RPA enables the process to robotically collect raw data from existing systems by recognizing graphical-level elements and inputting them into the LLM via the API to achieve efficient queries. After the LLM’s processing, the bot can automatically retrieve the output and transmit it back to the internal systems. However, this method has all the same problems of the RPA to user interface method, but is even more difficult to set up and maintain. In general, the authors said the best use for this method is systematic financial data extraction and analysis, regulatory compliance and reporting, and trail analysis and fraud detection.

The paper found this method is the most efficient in terms of the time it takes to extract 500 unstructured financial statements. The User Interface method alone took 1,800 minutes; the API method alone took 142 minutes; the combination of user interface plus RPA took 67 minutes; and the API plus RPA approach took 42 minutes. 

In terms of pure access costs, processing those 500 financial statements was just 83 cents through either the user interface or user interface plus RPA method versus $18 for the API and API plus RPA methods. However, given the time it takes to perform this task, the pure user interface method wound up being most expensive, as researchers added $52 in labor costs to those 83 cents. The API method alone, when accounting for labor costs, was the second most expensive, as the $18 access cost was combined with $31.25 in labor costs. 

All this in mind, the researchers concluded that the API plus RPA method was the most efficient in terms of both time and money. 

“The study finds that currently, the API-RPA is the most efficient method for large-scale accounting tasks. On the other hand, the API and API-RPA approaches are the most expensive methods to apply under the current price rate of GPT4 API,” said the paper. 

However, researchers warned that the discussions of each method are based on the current level of technological development and cost. 

“Some limitations might be overcome in the future with the adoption of new models. Additionally, the costs associated with each approach might change based on computing costs and market demand. Further research is needed to discuss additional application methods and cost-benefit models based on future developments of LLMs,” said the paper.

Senate unveils plan to fast-track tax cuts, debt limit hike

Published

on

Senate Republicans unveiled a budget blueprint designed to fast-track a renewal of President Donald Trump’s tax cuts and an increase to the nation’s borrowing limit, ahead of a planned vote on the resolution later this week. 

The Senate plan will allow for a $4 trillion extension of Trump’s tax cuts and an additional $1.5 trillion in further levy reductions. The House plan called for $4.5 trillion in total cuts.

Republicans say they are assuming that the cost of extending the expiring 2017 Trump tax cuts will cost zero dollars.

The draft is a sign that divisions within the Senate GOP over the size and scope of spending cuts to offset tax reductions are closer to being resolved. 

Lawmakers, however, have yet to face some of the most difficult decisions, including which spending to cut and which tax reductions to prioritize. That will be negotiated in the coming weeks after both chambers approve identical budget resolutions unlocking the process.

The Senate budget plan would also increase the debt ceiling by up to $5 trillion, compared with the $4 trillion hike in the House plan. Senate Republicans say they want to ensure that Congress does not need to vote on the debt ceiling again before the 2026 midterm elections. 

“This budget resolution unlocks the process to permanently extend proven, pro-growth tax policy,” Senate Finance Chairman Mike Crapo, an Idaho Republican, said. 

The blueprint is the latest in a multi-step legislative process for Republicans to pass a renewal of Trump’s tax cuts through Congress. The bill will renew the president’s 2017 reductions set to expire at the end of this year, which include lower rates for households and deductions for privately held businesses. 

Republicans are also hoping to include additional tax measures to the bill, including raising the state and local tax deduction cap and some of Trump’s campaign pledges to eliminate taxes on certain categories of income, including tips and overtime pay.

The plan would allow for the debt ceiling hike to be vote on separately from the rest of the tax and spending package. That gives lawmakers flexibility to move more quickly on the debt ceiling piece if a federal default looms before lawmakers can agree on the tax package.

Political realities

Senate Majority Leader John Thune told reporters on Wednesday, after meeting with Trump at the White House to discuss the tax blueprint, that he’s not sure yet if he has the votes to pass the measure.

Thune in a statement said the budget has been blessed by the top Senate ruleskeeper but Democrats said that it is still vulnerable to being challenged later.

The biggest differences in the Senate budget from the competing House plan are in the directives for spending cuts, a reflection of divisions among lawmakers over reductions to benefit programs, including Medicaid and food stamps. 

The Senate plan pares back a House measure that calls for at least $2 trillion in spending reductions over a decade, a massive reduction that would likely mean curbing popular entitlement programs.

The Senate GOP budget grants significantly more flexibility. It instructs key committees that oversee entitlement programs to come up with at least $4 billion in cuts. Republicans say they expect the final tax package to contain much larger curbs on spending.

The Senate budget would also allow $150 billion in new spending for the military and $175 billion for border and immigration enforcement.

If the minimum spending cuts are achieved along with the maximum tax cuts, the plan would add $5.8 trillion in new deficits over 10 years, according to the Committee for a Responsible Federal Budget.

The Senate is planning a vote on the plan in the coming days. Then it goes to the House for a vote as soon as next week. There, it could face opposition from spending hawks like South Carolina’s Ralph Norman, who are signaling they want more aggressive cuts. 

House Speaker Mike Johnson can likely afford just two or three defections on the budget vote given his slim majority and unified Democratic opposition.

How asset location decides bond ladder taxes

Published

on

Financial advisors and clients worried about stock volatility and inflation can climb bond ladders to safety — but they won’t find any, if those steps lead to a place with higher taxes.

The choice of asset location for bond ladders in a client portfolio can prove so important that some wealthy customers holding them in a taxable brokerage account may wind up losing money in an inflationary period due to the payments to Uncle Sam, according to a new academic study. And those taxes, due to what the author described as the “dead loss” from the so-called original issue discount compared to the value, come with an extra sting if advisors and clients thought the bond ladder had prepared for the rise in inflation.

Bond ladders — whether they are based on Treasury inflation-protected securities like the strategy described in the study or another fixed-income security — provide small but steady returns tied to the regular cadence of maturities in the debt-based products. However, advisors and their clients need to consider where any interest payments, coupon income or principal accretion from the bond ladders could wind up as ordinary income, said Cal Spranger, a fixed income and wealth manager with Seattle-based Badgley + Phelps Wealth Managers.

“Thats going to be the No. 1 concern about, where is the optimal place to hold them,” Spranger said in an interview. “One of our primary objectives for a bond portfolio is to smooth out that volatility. … We’re trying to reduce risk with the bond portfolio, not increase risks.”

The ‘peculiarly bad location’ for a bond ladder

Risk-averse planners, then, could likely predict the conclusion of the working academic paper, which was posted in late February by Edward McQuarrie, a professor emeritus in the Leavey School of Business at Santa Clara University: Tax-deferred retirement accounts such as a 401(k) or a traditional individual retirement account are usually the best location for a Treasury inflation-protected securities ladder. The appreciation attributes available through an after-tax Roth IRA work better for equities than a bond ladder designed for decumulation, and the potential payments to Uncle Sam in brokerage accounts make them an even worse asset location.

“Few planners will be surprised to learn that locating a TIPS ladder in a taxable account leads to phantom income and excess payment of tax, with a consequent reduction in after-tax real spending power,” McQuarrie writes. “Some may be surprised to learn just how baleful that mistake in account location can be, up to and including negative payouts in the early years for high tax brackets and very high rates of inflation. In the worst cases, more is due in tax than the ladder payout provides. And many will be surprised to learn how rapidly the penalty for choosing the wrong asset location increases at higher rates of inflation — precisely the motivation for setting up a TIPS ladder in the first place. Perhaps the most surprising result of all was the discovery that excess tax payments in the early years are never made up. [Original issue discount] causes a dead loss.”

The Roth account may look like a healthy alternative, since the clients wouldn’t owe any further taxes on distributions from them in retirement. But the bond ladder would defeat the whole purpose of that vehicle, McQuarrie writes.

“Planners should recognize that a Roth account is a peculiarly bad location for a bond ladder, whether real or nominal,” he writes. “Ladders are decumulation tools designed to provide a stream of distributions, which the Roth account does not otherwise require. Locating a bond ladder in the Roth thus forfeits what some consider to be one of the most valuable features of the Roth account. If the bond ladder is the only asset in the Roth, then the Roth itself will have been liquidated as the ladder reaches its end.”

RMD advantages

That means that the Treasury inflation-protected securities ladder will add the most value to portfolios in a tax-deferred account (TDA), which McQuarrie acknowledges is not a shocking recommendation to anyone familiar with them. On the other hand, some planners with clients who need to begin required minimum distributions from their traditional IRA may reap further benefits than expected from that location.

“More interesting is the demonstration that the after-tax real income received from a TIPS ladder located in a TDA does not vary with the rate of inflation, in contrast to what happens in a taxable account,” McQuarrie writes. “Also of note was the ability of most TIPS ladders to handle the RMDs due, and, at higher rates of inflation, to shelter other assets from the need to take RMDs.”

The present time of high yields from Treasury inflation-protected securities could represent an ample opportunity to tap into that scenario.

“If TIPS yields are attractive when the ladder is set up, distributions from the ladder will typically satisfy RMDs on the ladder balance throughout the 30 years,” McQuarrie writes. “The higher the inflation experienced, the greater the surplus coverage, allowing other assets in the account to be sheltered in part from RMDs by means of the TIPS ladder payout. However, if TIPS yields are borderline unattractive at ladder set up, and if the ladder proved unnecessary because inflation fell to historically low levels, then there may be a shortfall in RMD coverage in the middle years, requiring either that TIPS bonds be sold prematurely, or that other assets in the TDA be tapped to cover the RMD.”

The key takeaways on bond ladders

Other caveats to the strategies revolve around any possible state taxes on withdrawals or any number of client circumstances ruling out a universal recommendation. The main message of McQuarrie’s study serves as a warning against putting the ladder in a taxable brokerage account.

“Unsurprisingly, the higher the client’s tax rate, the worse the outcomes from locating a TIPS ladder in taxable when inflation rages,” he writes. “High-bracket taxpayers who accurately foresee a surge in future inflation, and take steps to defend against it, but who make the mistake of locating their TIPS ladder in taxable, can end up paying more in tax to the government than is received from the TIPS ladder during the first year or two.”

For municipal or other types of tax-exempt bonds, though, a taxable account is “the optimal place,” Spranger said. Convertible Treasury or corporate bonds show more similarity with the Treasury inflation-protected securities in that their ideal location is in a tax-deferred account, he noted.

Regardless, bonds act as a crucial core to a client’s portfolio, tamping down on the risk of volatility and sensitivity to interest rates. And the right ladder strategies yield more reliable future rates of returns for clients than a bond ETF or mutual fund, Spranger said.

“We’re strong proponents of using individual bonds, No. 1 so that we can create bond ladders, but, most importantly, for the certainty that individual bonds provide,” he said.

Why IRS cuts may spare a unit that facilitates mortgages

Published

on

Loan applicants and mortgage companies often rely on an Internal Revenue Service that’s dramatically downsizing to help facilitate the lending process, but they may be in luck.

That’s because the division responsible for the main form used to allow consumers to authorize the release of income-tax information to lenders is tied to essential IRS operations.

The Income Verification Express Service could be insulated from what NMN affiliate Accounting Today has described of a series of fluctuating IRS cuts because it’s part of the submission processing unit within wage and investment, a division central to the tax bureau’s purpose.

“It’s unlikely that IVES will be impacted due to association within submission processing,” said Curtis Knuth, president and CEO of NCS, a consumer reporting agency. “Processing tax returns and collecting revenue is the core function and purpose of the IRS.”

Knuth is a member of the IVES participant working group, which is comprised of representatives from companies that facilitate processing of 4506-C forms used to request tax transcripts for mortgages. Those involved represent a range of company sizes and business models.

The IRS has planned to slash thousands of jobs and make billions of dollars of cuts that are still in process, some of which have been successfully challenged in court.

While the current cuts might not be a concern for processing the main form of tax transcript requests this time around, there have been past issues with it in other situations like 2019’s lengthy government shutdown.

President Trump recently signed a continuing funding resolution to avert a shutdown. But it will run out later this year, so the issue could re-emerge if there’s an impasse in Congress at that time. Republicans largely dominate Congress but their lead is thinner in the Senate.

The mortgage industry will likely have an additional option it didn’t have in 2019 if another extended deadlock on the budget emerges and impedes processing of the central tax transcript form.

“It absolutely affected closings, because you couldn’t get the transcripts. You couldn’t get anybody on the phone,” said Phil Crescenzo Jr., vice president of National One Mortgage Corp.’s Southeast division.

There is an automated, free way for consumers to release their transcripts that may still operate when there are issues with the 4506-C process, which has a $4 surcharge. However, the alternative to the 4506-C form is less straightforward and objective as it’s done outside of the mortgage process, requiring a separate logon and actions.

Some of the most recent IRS cuts have targeted technology jobs and could have an impact on systems, so it’s also worth noting that another option lenders have sometimes elected to use is to allow loans temporarily move forward when transcript access is interrupted and verified later. 

There is a risk to waiting for verification or not getting it directly from the IRS, however, as government-related agencies hold mortgage lenders responsible for the accuracy of borrower income information. That risk could increase if loan performance issues become more prevalent.

Currently, tax transcripts primarily come into play for government-related loans made to contract workers, said Crescenzo.

“That’s the only receipt that you have for a self-employed client’s income to know it’s valid,” he said.

The home affordability crunch and rise of gig work like Uber driving has increased interest in these types of mortgages, he said. 

Contract workers can alternatively seek financing from the private non-qualified mortgage market where bank statements could be used to verify self-employment income, but Crescenzo said that has disadvantages related to government-related loans.

“Non QM requires higher downpayments and interest rates than traditional financing,” he said.

In the next couple years, regional demand for loans based on self-employment income could rise given the federal job cuts planned broadly at public agencies, depending on the extent to which court challenges to them go through.

Those potential borrowers will find it difficult to get new mortgages until they can establish more of a track record with their new sources of income, in most cases two years from a tax filing perspective.
