How to use AI Copilot for tax-season prep

Tax season is mostly an organization problem dressed up as a math problem. If your records are clean, the math is what your tax software is for. If your records are not clean, no amount of software helps. This guide walks through how to use AI Copilot to take a year of mixed personal and deductible activity and turn it into a clean export your accountant — or your tax tool — will accept without follow-up questions.

The whole flow takes about 45 minutes for a typical individual filer, longer if you have business income mixed in. You do it once a year. Block the time on a weekend morning, make coffee, and follow the steps in order.

Step 1: confirm the year of data is complete

Before anything else, open Accounts → Connections and confirm every account that touched money last year is still connected and has a green status. The most common tax-prep failure is realizing in March that one credit card disconnected in August and you have four missing months. Reconnect anything stale before you start categorizing — it is much easier to fix now than to merge two exports later.

If you closed an account during the year, that's fine — closed accounts retain their historical data. You only need active connections for accounts that are still receiving transactions.

Step 2: ask Copilot for a deduction sweep

Open the AI Copilot panel and use this prompt, adjusted for your situation:

Review all transactions from January through December for anything that looks like a potentially deductible expense. Flag categories I should review: home office, professional development, software subscriptions, business travel, charitable giving, medical, and anything tagged 'work'. Group by category and show the running total.

Copilot will return a grouped list. Do not trust it blindly — this is a first pass, not a final answer. Its job is to surface candidates so you can confirm or reject each one. Expect about 80% of suggestions to be correct, 15% to need re-categorization, and 5% to be wrong in interesting ways.

Click through each group and use the bulk-edit tools to confirm, re-tag, or split mixed transactions. The "split transaction" tool is especially useful for things like a hardware store run where part was personal and part was a deductible repair.

Step 3: handle the awkward categories

Three categories almost always need manual attention.

Home office and utilities. If you claim a home office percentage, tag the relevant utilities, internet, and rent/mortgage interest transactions with a home-office tag. Do not try to apply the percentage in MoneyPatrol — apply the full amount, tag it, and let your tax software or accountant apply the percentage at filing time. Mixing the two creates confusion.

Subscriptions that are part personal, part work. Use the split-transaction tool. If a subscription is, say, 60% work, split each monthly charge into two lines — one tagged work-subscription, one personal. Do this once with a bulk rule and it applies retroactively.

Charitable giving. Tag with charity and confirm each transaction has a counterpart receipt. Copilot can list transactions but cannot verify you actually have the documentation; that part is on you.

Step 4: ask Copilot for the sanity check

Once you've categorized, run a second prompt:

Compare this year's totals for [home-office, work-subscription, charity, professional-development] to last year. Flag any category that's more than 25% higher or lower than last year, and explain the largest contributing transactions.

This is the step almost nobody does, and it is the single most useful one. Big year-over-year deltas are usually either (a) a real change in your life that you should remember to mention to your accountant, or (b) a categorization error that would have triggered a question on review. Either way, you want to find it now, not after filing.

Step 5: export

Open the Reports view, select the calendar year, choose the categories you tagged, and export to CSV. The CSV includes date, payee, amount, category, tags, and your notes. Most tax software accepts this directly; accountants typically prefer it as a single file rather than separate ones per category.

Save the export with a clear filename — MoneyPatrol-2025-tax-export.csv is enough — and store it alongside your receipts. We recommend keeping the file for seven years, which matches most jurisdictions' record-keeping requirements.

Step 6: write yourself a note for next year

Open a plain text file or a note in your phone and write down the three things you wish past-you had done differently. Common entries: "tag work travel as it happens, not in March", "keep the charity receipts in one folder", "ask the accountant about the home office percentage before December". This note is worth more than any tax tool — it makes next year's version of this process 30 minutes instead of 45.

What Copilot will not do

A few honest limits. Copilot will not file your taxes, will not give legal or tax advice, and will not know your jurisdiction's specific deduction rules. It is a sorting and sense-checking assistant, not a tax preparer. Use it to make the messy part of tax prep — the cleanup — fast and accurate. Then hand the clean output to whatever tool or human files for you.

That division of labor is the whole point. The math is the easy part. The organization is what eats the weekend.
