Leveraging AI: Best Practices for AI Copilot in Tax Preparation and Accounting

Artificial intelligence, especially generative AI tools like ChatGPT, is rapidly transforming various industries. With over 400 million users as of February 2025, according to CNBC, its impact on business productivity is undeniable. For accounting professionals, leveraging AI means new opportunities to streamline tasks, gain insights, and enhance communication.

At its core, ChatGPT is a large language model (LLM) developed by OpenAI. It uses natural language processing (NLP) to understand and generate human-like text, acting as a conversational AI chatbot. You simply input prompts or questions, and ChatGPT responds with relevant text, images, or even audio.

Software applications can integrate ChatGPT’s capabilities through API connections, adding powerful AI functionalities to various programs. This allows for seamless incorporation into existing workflows, enhancing their potential.

Understanding ChatGPT’s Limitations in Accounting

While incredibly powerful, ChatGPT isn’t a silver bullet. Its effectiveness largely depends on your ‘prompt engineering’ skills – how well you craft your questions. Human oversight remains crucial; always fact-check and refine its output, as the AI isn’t yet perfect.

Remember, privacy and security are paramount. OpenAI advises against entering sensitive information into ChatGPT. Also, its training data has a cutoff date (e.g., September/November 2023 for GPT-4o/4 models), so it might not have the absolute latest information unless you utilize its search features or provide current data as input.

12 Smart Ways to Use AI as an Accounting Copilot

Despite these limitations, accountants can use ChatGPT as a powerful assistant. Here are 12 practical applications that can significantly boost your accounting productivity:

1. Invoice Processing

You can use ChatGPT to assist with aspects of invoice processing, like coding expenses. However, for maximum efficiency and accuracy, integrating AI features directly into AP automation software, such as Tipalti, offers superior results. These integrated solutions enhance account coding predictions and improve purchase order matching.

2. Coding Expenses

Manually coding expenses to your chart of accounts can be time-consuming and error-prone. While ChatGPT can offer suggestions, dedicated AP automation software with built-in AI, like Tipalti, provides automatic coding features for supplier invoices. This digital transformation eliminates manual data entry, significantly reducing errors and saving up to 80% of your processing time.

3. Data Cleansing

Before migrating data or running analyses, clean data is essential. ChatGPT can help you cleanse accounting data by removing unwanted characters, standardizing customer names, or eliminating duplicate entries in spreadsheets or master files.

4. Formatting Output

If your current accounting software’s report formats aren’t ideal, ChatGPT can reformat financial statements, reports, and tables. You can also use it to generate CSV files or sort data efficiently for various uses in spreadsheets and other programs.

5. Report Narratives and Notes

Enhance your financial reports by using ChatGPT to generate narratives, notes, and even suggestions for profitability improvements. It can analyze significant account balance changes on your balance sheet or income statement across comparative periods.

For formal Notes to Financial Statements, always fact-check and supplement ChatGPT’s output with the latest GAAP or IFRS standards. Public company CFOs can also leverage ChatGPT to analyze results, prepare conference call scripts, and anticipate analyst questions.

6. Generating Computer Code

Need a script or formula? ChatGPT can generate computer code in various languages, including JavaScript, Python, R, or Excel macro code and formulas. If the code has issues, simply ask ChatGPT to revise it based on the problems you encounter.

7. Data Analysis for Decision-Making

Leverage ChatGPT to analyze financial data for anomalies in trends, amounts, or percentage changes, which require further investigation. This insightful analysis can highlight opportunities for operational improvements, leading to cost reductions and increased profitability. Tipalti’s ‘Ask Tipalti AI SM’ digital assistant, with its built-in ChatGPT features, helps businesses gain real-time financial data insights and conduct spend analysis.

8. Business Plan and Pitch Deck Research

Crafting a business plan or pitch deck requires extensive research. ChatGPT can perform preliminary research, helping you brainstorm ideas and generate text or images for your presentation. Remember to fact-check its findings and provide up-to-date information, especially when using its ‘Search’ and ‘Deep Research’ features (available to Pro users).

9. Preliminary Financial Forecasts and Budgets

ChatGPT can assist in creating preliminary demand predictions, financial forecasts, and budgets. However, these are starting points; always apply your expert judgment and current market information to adjust and refine these initial projections for accuracy.

10. Audits

In external audits, analytical reviews help identify anomalies in financial data. ChatGPT can act as an auditing aid by analyzing financial data for such discrepancies. As audit automation programs increasingly integrate ChatGPT via API, its utility in preparing general ledger account reconciliation schedules and other audit tasks will grow.

11. Tax and Legislation Compliance Research

While ChatGPT is not yet equipped to prepare accurate tax returns, it proves invaluable for tax research. For instance, you can use it to summarize new tax laws or government legislation. Best practices for AI copilot for tax preparation involve leveraging ChatGPT’s ‘Search’ feature for current information or inputting legislation content as a PDF for a detailed summary, always verifying the output with a human expert.

12. Business Communications and Brainstorming

From drafting emails and reports to brainstorming new ideas, ChatGPT excels in business communications. Provide prompts outlining your desired writing style, context, and tone, then review and revise the suggested content for accuracy and conciseness. Tools like GrammarlyGO, which utilizes ChatGPT, also offer advanced editing capabilities.

Recent ChatGPT Features and Enhancements

OpenAI has continuously evolved ChatGPT, introducing a host of features that significantly boost its capabilities:

In March 2023, the GPT-4 Release brought multimodal capabilities, accepting both text and image inputs, and allowed file attachments. Plugin Support also launched, enabling integration with third-party services. The Code Interpreter (July 2023) offered data analysis and code execution directly within the chat interface, with its features soon to be fully integrated into the Responses API.

Further enhancements included Voice and Image Interaction (September 2023) and DALL·E 3 Integration (October 2023) for image generation. GPT-4 Turbo (November 2023) offered a faster, more cost-effective version with an expanded context window.

The GPT-4o (‘Omni’) Release in May 2024 (with a March 2025 update) significantly enhanced multimodal interactions, processing text, audio, and images in real-time. This version is faster and demonstrates a superior understanding of vision and audio, improving instruction following, conciseness, and coding tasks.

Recent developments include the o1 Model Introduction (September 2024) focusing on advanced reasoning, and the Search feature (October 2024), now available to all users, allowing ChatGPT to access the internet for more recent information and provide web source links.

The Operator AI agent (January 2025) offers autonomous decision-making and task execution, such as browsing the internet and performing transactions, initially for Pro users.
