People forget to include tax forms (1099-INT, 1099-DIV, etc.) when filing, leading to IRS letters, amendments, and anxiety.
Connects to bank accounts, brokerages, and employer portals via API/Plaid to build a checklist of expected tax documents, then compares against what you've actually uploaded to your tax software before filing.

Real and recurring pain — 410 upvotes on a single Reddit post confirms this. IRS CP2000 notices affect millions annually. However, for most people it happens once, they panic, file an amendment, and move on. It's acute but infrequent (once/year), which limits urgency outside of Jan-April.
~150M individual tax returns filed annually in the US. ~60% self-file. Target is the subset with multiple accounts — estimated 30-50M filers. At $9.99/year, theoretical TAM is $300-500M. Realistic serviceable market is much smaller initially, but the wedge is solid.
This is the weakest link. Tax filers are notoriously cheap — they'll spend hours to save $20. Free alternatives (IRS transcript) exist even if clunky. $9.99/year is low enough to not trigger sticker shock, but converting free users will be hard. The value prop is 'peace of mind' which is hard to monetize. People pay AFTER the pain (amendment fees, CPA costs) not before.
Harder than it looks. Plaid gives you account connections but does NOT reliably surface which 1099 forms will be issued by each institution. You'd need to infer from transaction data (interest earned > $10 = expect 1099-INT), which is heuristic-based and error-prone. Connecting to employer portals is fragmented. Comparing against 'what you uploaded to tax software' requires integration with TurboTax/H&R Block APIs, which are limited or nonexistent. A solo dev could build a simplified version (manual account entry + checklist) in 4-8 weeks, but the full automated vision is 6-12 months.
This is the strongest signal. Despite massive incumbents (Intuit, H&R Block), NOBODY does proactive cross-referencing of expected vs. actual tax documents from the filer's perspective. The IRS transcript is the closest thing and it's buried, delayed, and has zero UX. There's a genuine gap between 'I have 7 financial accounts' and 'I filed forms for all 7.'
Natural annual subscription since taxes are yearly. But once-a-year usage makes retention tricky — users may cancel after filing and forget to re-subscribe. Need to either charge annually with auto-renew or expand to year-round value (tax document vault, estimated tax tracking, mid-year tax optimization).
- +Genuine unmet need validated by organic user pain signals — nobody solves this specific problem well
- +Low price point ($9.99/yr) reduces adoption friction and makes impulse purchase viable
- +Increasing market tailwinds: more gig workers, more accounts, stricter IRS matching
- +Clear differentiation from incumbents who all have this blind spot
- +Potential to become a trust wedge into broader tax/financial planning
- !TurboTax/Intuit could ship this feature in one sprint if they wanted to — you're betting they stay complacent
- !Plaid data may not reliably predict which 1099s will be issued, leading to false positives/negatives that destroy trust
- !Extreme seasonality: 90% of usage in Jan-April, makes growth metrics noisy and retention hard to measure
- !Financial data permissions are sensitive — one breach or misuse headline kills the product
- !IRS Get Transcript could improve their UX and eat your lunch for free
TurboTax connects to financial institutions via Intuit's partnerships to auto-import W-2s, 1099s, and investment income. Has a built-in review step before filing.
Free IRS tool that shows all W-2s, 1099s, and other income documents reported to the IRS by third parties for a given tax year.
Personal finance aggregators that connect to all your bank/brokerage accounts and could theoretically surface tax-relevant activity
Platforms primarily for businesses to FILE 1099s, but also allow recipients to access and organize 1099s they've received.

Skip the full Plaid automation for V1. Build a simple web app where users manually list their financial institutions (banks, brokerages, employers, freelance clients). Auto-generate a personalized checklist of expected tax forms based on account types. Let them check off forms as they gather them. Add a 'ready to file' confidence score. This is buildable in 4-6 weeks, validates demand without the Plaid complexity, and gives you a user base to upsell automation to later.
Free checklist tool (manual entry, up to 3 accounts) → $9.99/yr for unlimited accounts + Plaid auto-detection + audit-risk scoring → $29.99/yr premium with document vault, amendment assistance, and year-round estimated tax alerts → B2B licensing to tax prep software companies or financial advisors who want to offer this to clients
8-12 weeks to MVP launch, first revenue in 14-16 weeks if you launch by early January to catch tax season. Critical constraint: if you miss the Jan-April window, you're waiting a full year for meaningful traction. Tax season 2027 filing (Jan-Apr 2027) is your realistic first revenue window.
- “forgot a 1099-INT form”
- “honestly forgot I even banked with them”
- “I just submitted my tax return forms yesterday and they were accepted. I realized today that I forgot”
