NerdWallet Study: AI and Taxes
A new analysis from NerdWallet shows that using AI for help with filing taxes shows promise but has serious downsides to keep in mind.
To see how well the current state of available services performed, NerdWallet testers asked three AI services:
Questions about tax rules.
To estimate a tax bill after uploading a W2.
For advice about filing taxes for the first time.
To recommend a tax software product.
Responses were then scored for accuracy and consistency.
AI chatbots were able to address our questions, and they had great recall of tax rules.
However, when faced with requests for personalized answers, quality wavered. On many occasions, the services made faulty assumptions about the person asking the questions. When testers asked for advice using an identical prompt, the AI service didn’t always give consistent recommendations.
In its current state, these services may be fun to experiment with. But, when filing taxes or making financial decisions with long-term tax implications, take its advice with a grain of salt.

Elizabeth Renter, Senior Economist
“The recurring dissent and particularly the fact that people are disagreeing in both directions — some wishing to hold rates as-is and others to cut more — is evidence of the difficult economic period we’re in.”

Our standards
All of our data projects go through a rigorous process before publication. During the planning stage, editors, data writers and analysts, subject matter experts and communications specialists share perspectives and ask tough questions of all potential ideas. We use data from only the most reputable sources, and our methodologies and calculations are all checked and rechecked for sound rationale and accuracy. Our data-driven work also goes through a minimum of three rounds of editing before publication.
Our nationally representative surveys are conducted in collaboration with The Harris Poll. We've been working with The Harris Poll since 2014 to field statistically sound and robust surveys weighted to be representative within age, gender, race/ethnicity, region, household income, education, employment, marital status and size of household where necessary to align with their actual proportions in the population.
