Tax prep is mostly organizing, not expertise.
Whether you file your own taxes with software or pay a CPA, the hardest, most miserable part of tax season isn't the actual filing. It's the pre-filing pile — the shoebox of receipts, the "wait, did I get a 1099 for that?", the scavenger hunt for last year's return, the list of questions you forgot to ask until April 10th.
That pre-filing pile is exactly what Claude is built to handle. Organizing, categorizing, decoding jargon, drafting question lists, reading last year's return to figure out what still applies — this is the lion's share of the work, and none of it is "tax advice." It's just prep work.
What this page is NOT.
It is not tax advice. Claude will not tell you whether to take the standard deduction or itemize. It will not tell you whether your home office qualifies. It will not tell you how to structure your side-business income. Those are questions for your CPA, your tax software's explanations, or the IRS publications themselves. Claude's job here is to get you organized and informed enough that those conversations are short, accurate, and cheap.
1. "What do I actually need to gather?"
Every filer's pile looks different. A stay-at-home mom with one W-2 household income needs a very different list than a mom who also does Etsy, owns a rental, or whose spouse is self-employed. Claude tailors the list to your situation. Run this in Money Command Center so it picks up your situation block from the custom instructions.
The "what to gather" prompt
Tax season prep. Based on my situation (in your custom instructions), build me a complete gather-list of everything I need to collect before I file or meet with my CPA this year. Organize it into these buckets:
1. INCOME DOCS: every form I should expect to receive (W-2s, 1099s of every kind, K-1s, SSA, unemployment, etc.) and who typically sends each one.
2. DEDUCTION / CREDIT DOCS: forms I need if I want to claim anything — mortgage interest (1098), student loan interest (1098-E), tuition (1098-T), childcare receipts + provider tax IDs, charitable donation letters, medical expenses over my AGI threshold, state/local tax receipts.
3. LIFE-EVENT DOCS: anything from a marriage, divorce, birth, adoption, home purchase/sale, move across state lines, retirement account rollover, stock sale, etc.
4. REFERENCE DOCS: last year's filed return (federal + state), any estimated-tax payment confirmations I made during the year, any IRS or state correspondence I received during the year.
For each bucket, tell me: what I'm looking for, where it typically comes from (employer, bank, broker, school, etc.), when it usually arrives (dates), and whether it's almost-always paper, almost-always digital, or both.
Flag anything that's easy to miss — the common "oops, I didn't know I was supposed to get that" items for someone with my situation.
Save the list. Use it as a checklist.
Print Claude's response, or save it to Money Command Center's Files panel as "Tax Gather List — [Year]". As docs come in through January and early February, check them off. By mid-February you'll know exactly what's still missing and have time to chase it down — way better than discovering on April 10th that you never received a 1099 you needed.
2. Decode the forms without Googling each one.
Once the pile starts arriving, most of it is jargon. Claude is very good at translating tax jargon into plain English. The rule: any form you don't understand, paste the form name (or the whole blank form) and ask.
Decode any tax form in plain English
I have a [FORM NAME, e.g., "1099-NEC" or "W-2" or "1098-T"] in front of me. Walk me through it in plain English:
1. What is this form, in one sentence?
2. Who typically sends it? (Who should I have received this from?)
3. What each box/line means — go through them in order. For boxes I can ignore unless they're filled in, say so.
4. What this form affects on my actual tax return — does this add to income, add to deductions, trigger a credit, etc.?
5. Common mistakes people make with this form.
6. One thing my tax preparer or tax software will almost certainly ask me about this form.
Keep it in plain language — like you're explaining it to a friend, not reading me the IRS instructions.
"Which 1099 is this and what's the difference?"
I received a 1099 and I'm not sure if it's the right kind or if I was supposed to get a different version. Explain the common 1099 forms to me in plain English:
- 1099-NEC (Nonemployee Compensation)
- 1099-MISC (Miscellaneous Information)
- 1099-K (Payment Card and Third-Party Network Transactions)
- 1099-INT (Interest Income)
- 1099-DIV (Dividends and Distributions)
- 1099-R (Retirement distributions)
- 1099-G (Government payments, e.g., unemployment, state tax refund)
- 1099-B (Broker transactions)
For each one: who sends it, when you'd get it, and one example of the kind of income it covers. Then tell me — in my situation — which of these I might realistically receive this year.
The "explain this box" trick.
When you get your W-2, the boxes are numbered 1 through 20+ and most of them are cryptic. You don't need to understand all of them — but if your tax software asks about "Box 12 code DD" and you don't know what that is, you can ask Claude: "What is Box 12 code DD on a W-2?" and get a clean 30-second answer.
3. Read last year's return. Find the "what still applies" list.
Your last filed tax return is a cheat sheet for this year. It shows you every category that applied to your household, every deduction you actually took, every credit you qualified for. Most of that probably still applies — and checking each item is what stops you from missing something this year.
Read last year's return — paste or upload the PDF first
Attached/pasted is my filed federal tax return from last year. Please do three things:
1. PLAIN-ENGLISH SUMMARY: in one short paragraph, summarize the return. What kind of income did we have? What were the biggest deductions or credits? What was the overall shape (refund vs. owed)? No numbers with more than 3 significant digits — I just want the shape.
2. CATEGORY LIST: list every schedule and supporting form that was filed (Schedule A, Schedule C, Schedule E, Form 2441 for childcare, etc.) and in one sentence, what each one was about.
3. "STILL APPLIES?" CHECKLIST: for each category above, make a yes/no/maybe table asking whether this category still applies this year. If "maybe," note what changed (e.g., "you had childcare expenses — did kids enter school this year?"). If "no," note what you'd expect to be different.
Treat this as a planning document, not tax advice. I'm using it to make sure I'm gathering the right things, not to make filing decisions.
Privacy-pass your return before uploading.
Your filed return has SSNs in the top corner. Before uploading or pasting: open the PDF in any PDF tool, redact the SSN boxes (or photograph only the pages that don't show SSNs — usually the first page is the only one with SSNs, the schedules don't repeat them). Claude does not need your SSN to do any of the analysis here.
The "what changed this year" follow-up.
After the checklist, run: "Here's what changed in my household this year: [kid started daycare, moved states, started a side business, etc.]. How might each of those affect what I need to gather or bring up with my CPA?" Claude will map the life changes to the tax categories they touch. The difference between walking into your CPA appointment prepared and walking in blank.
4. Build the CPA question list — and know when to stop.
Two moves on this section. The first is the prompt that turns your gather-list + "what changed" into a clean list of questions to ask your CPA (or plug into your tax-software's help search). The second is the chart that tells you when the situation is not a Claude situation, and you need a real human.
The CPA / tax-software question list
Based on (a) my situation, (b) what I gathered from last year's return, and (c) what's changed this year, build me a prioritized question list to take into my CPA appointment (or my tax-software session if I'm filing myself).
Format:
- Group questions by topic (income, deductions, credits, life changes, state-specific items).
- For each question, write it the way I'd actually say it out loud — plain English, no legal language. Example: not "What is the tax treatment of my Sec. 199A QBI deduction?" but "I have Etsy income — does the 20% pass-through deduction apply to me?"
- Mark each one as HIGH PRIORITY (will likely affect my refund/bill) or NICE TO KNOW (background).
- Cap it at 12 questions total. I want a focused list, not an overwhelming one.
- At the bottom, list 2-3 DOCUMENTS I should bring to the appointment that support the high-priority questions.
Keep it practical. I want to walk out of my meeting with clear answers, not with more homework.
When to close Claude and call a pro.
Most tax situations are in the green or yellow zone — organize the pile, decode the forms, show up informed. But a handful of situations are red-zone from the start.
GREEN — Claude helps
Organize & decode
- Building your gather list
- Decoding forms & boxes
- Reading last year's return for context
- Drafting the CPA question list
- Organizing receipts by category
- Understanding what a notice means, plain English
YELLOW — Claude drafts, pro confirms
Get organized, then verify
- First-year side business / self-employment
- Rental property bought or sold this year
- Stock, crypto, or RSU transactions
- Moved states mid-year
- Inherited money or property
- Large 1099-K from a hobby you're not sure is a business
RED — call a pro first
Don't DIY these
- IRS notices (CP2000, CP14, levies, audits)
- Debt-collector lawsuits related to taxes
- Wage garnishment or bank levies
- Divorce-year finances
- Inheritance distribution disputes
- Back-taxes / offer-in-compromise situations
- Any situation where you'd expect to hire a lawyer
If you got a notice — do this.
You can still use Claude for a plain-English read of the notice. "Explain this IRS notice in plain English — what are they claiming, what's the deadline to respond, and what are my options in general terms?" That context helps you walk into the CPA or tax attorney's office already understanding what's going on. But don't draft the response with Claude, and never send anything to the IRS without a pro reviewing it.
5. The shoebox — one prompt.
There's almost always a "receipts for taxes" pile somewhere — a shoebox, a folder, a stack on the desk, a manila envelope. Take thirty minutes, snap photos of every receipt in it (or scan them with the Notes/Files app on your phone), and run this. Claude sorts them into the categories that matter for filing and tells you which ones probably don't need to be kept.
Receipt organizer — after uploading receipts or pasting a list
Attached (or pasted below) are receipts from my [tax year] receipt pile. Please:
1. READ THEM: for each receipt, pull out date, vendor, amount, and what it appears to be for (best guess from the merchant name).
2. CATEGORIZE into likely tax categories for someone in my situation: medical, charitable, business/self-employment expense (if applicable), childcare (if applicable), education, home-office (if applicable), state-specific (e.g., sales tax if I'm in a state where that's deductible). Add an "unclear" or "personal — not deductible" bucket for ones that don't fit.
3. BUILD A TABLE: Date | Vendor | Amount | Category | Verdict (keep / probably toss / ask CPA)
4. CATEGORY TOTALS at the bottom.
5. FLAG ANYTHING WEIRD: a receipt that looks like it might be duplicated, a partial/faded one where I might need to hunt down a replacement, anything that looks like it might have been paid with a business card that's also on a 1099.
Keep the table clean enough to paste into Google Sheets.
Pro bonus — Cowork scans receipts straight into the Project.
On Pro with Cowork + Google Drive connected, you can drop photos of receipts into a Drive folder called Tax Receipts as they come in during the year. Then once a quarter (or before tax season), run the dispatch prompt below and Cowork reads everything in the folder, runs the organizer, and saves the result back to Drive. Requires Cowork — see the Cowork setup for setup.
Pro · Cowork receipt-scan dispatch
Cowork: look in my Google Drive folder "Tax Receipts" for any receipts I've added since the last scan. For each one, extract the date, vendor, amount, and best-guess category. Run the receipt organizer prompt on all of them.
Save two files to my "Money Command Center" Drive folder:
1. "Tax Receipts Sorted YYYY-Q[quarter].xlsx" — the full sorted table with totals by category.
2. "Tax Receipts Questions YYYY-Q[quarter].md" — any receipts you flagged as "unclear" or "ask CPA," so I have a short list of open items.
Pause and show me both files before saving. Don't delete or move the original receipts in the Tax Receipts folder — leave them where they are.
