The Problem

Tax season turns a working freelancer into an unpaid data-entry clerk. The designer who lived in Stripe all year now has forty-seven payouts, a Venmo side hustle, Cash App reimbursements that might be income, a PayPal 1099-K they did not expect, and Drive receipts named scan004. TurboTax wants a spreadsheet. Their “books” are a Notes app. Their CPA wants $1,200 and a shoebox. They spend a weekend reconstructing a year they already lived.

The job is split across tools that refuse to finish it. DIY filing giants are April products: import, click, pay per return, leave. Cloud books keep a ledger and stop before e-file. Estimators spit a quarterly number and wish you luck at the IRS portal. This site already has both narrower wedges — Quarterly Tax Estimator for Freelancers owns “what do I pay June 15,” and AI Bookkeeping for Freelancers owns a clean P and L. Neither transmits a return. The freelancer still copy-pastes into someone else’s filing flow, which is where errors and missed deductions actually happen.

The pain is seasonal and loud. r/personalfinance (14.1M), r/tax (383K+), and r/taxpros (82.7K+) spend January through April comparing TurboTax fees and begging for a simpler 1099 path. Facebook’s Self Employed Support Group (45K+) repeats it: too many platforms, too much manual entry, not enough trust in “AI that files” unless the books and the forms are the same system. A CPA is correct for K-1s, employees, and multi-state nexus. It is the wrong answer for a sole prop making $40K–$150K who needs Schedule C prepared from real payouts and a licensed transmitter on the other end.

Willingness to pay is not the blocker. Incumbents already extract $69–$120+ per DIY return; AI tax SaaS lands at $39–$69/month. The blocker is the last mile: books that never become a filed return, or a return typed from stale CSVs.

The Solution

MyTaxGuy is tax-prep software for 1099 sole props that keeps the books and assembles the return from those books, then transmits through a licensed e-file partner. It is not a CPA, not legal advice, and not an LLM inventing your income. The user connects Stripe, PayPal, and a bank via Plaid, drops receipts into Drive, and lets categorization run all year. In January the same ledger becomes a Schedule C draft, a 1040-ES worksheet, and 1099-NEC output if they paid contractors. The human reviews every figure, signs, and the transmitter pipes it to the IRS. You sell closed-loop prep, not a chatbot that “does taxes.”

Scope v1 like a weekend product. One federal return, one state, Schedule C / sole-prop only. No K-1s, no employees, no rentals, no international. Complex filers stay with Block’s hybrid or a human. ICP: Upwork designer, Substack writer, Stripe consultant making $30K–$150K — too busy to reconcile, not rich enough for a year-round accountant. $49/month in filing season, $29/month if they keep the books alive.

Trust is the engineering. Categorization can use a model. Tax math cannot. Totals come from posted transactions. Form fields map through a rules table you own. The model writes explanations (“this DoorDash cluster looks like meals — confirm”) and never writes a box on the return. E-file is a transmitter API (TaxBandits or equivalent), not a weekend founder becoming an IRS Authorized e-file Provider. Bank tokens stay server-side. MFA on paid plans. No training on customer ledgers.

How it works:

Connect income — Plaid Link for bank and cards; Stripe and PayPal for payouts; Google Drive for receipts. One onboarding, not a chart-of-accounts seminar.
Books run in the background — Transactions auto-categorize against learned vendor rules. Monthly P and L, deduction flags, and a running self-employment profit the user can correct in a queue.
Review the assembled return — Deterministic mapping fills Schedule C from the ledger. The UI shows source transaction to form line. The user confirms; nothing transmits on a guess.
E-file, then stay current — A licensed transmitter sends the return and returns an acknowledgment. Year-round mode keeps books live and preps 1040-ES amounts so April is a review, not archaeology.

Retention is the year-round ledger. If books die in June, you become TurboTax with extra steps. Always-on is the plan you actually want them on.

Market Research

DIY tax software is mature. Freelancer-native books-plus-file is still a land grab. The money is in the category; the gap is the 1099 worker with five payout platforms and no staff accountant.

Global tax management software is $25.09B in 2025, headed to $59.85B by 2034 at a 10.14% CAGR (Precedence Research). That is the broad TAM. You are the freelancer slice.
US tax preparation software nearly doubles from $6.4B in 2024 to $12.9B by 2032 at a 9.3% CAGR (Global Risk Community compilation). South US leads value; West US leads growth.
TurboTax still owns more than 60% of US consumer DIY e-file, 44M+ filings a year; H&R Block sits around 15–20% online (IBISWorld-class share in the competitive pack). Incumbents won W-2 simplicity. They did not win multi-platform 1099 ops.
Independent work is structural — about 36% of the US workforce as of 2024 in the community analysis. These people file every year whether or not they bought QuickBooks.
Firms are buying the thesis from the other side: 47% of tax and accounting firms planned to increase AI spend in 2025 (Thomson Reuters). That does not mean a CPA shop will sell a $29 Schedule C product to Stripe solopreneurs.
Search pays accounting prices. Trend discovery on “freelancer tax filing automation bookkeeping 1099” returned 15 keywords and about 2.54 million combined monthly searches. Head terms are QuickBooks-shaped (1.83M on “quick book accounting package”; “online accounting” at 60.5K, $40.75 CPC). “1099 contractor” is 8.1K at $3–$6 CPC. Rank for Schedule C + e-file; do not outbid Intuit on QuickBooks. r/tax traffic spikes 30–60% January–April.

Stage: competitive / early growth for freelancer-centric filing; mature for generic DIY. Twenty-plus AI-tax tools since 2022 and $200M+ cited into the vertical. No default pocket accountant that both books and files. That window closes when TurboTax ships a Stripe-native Schedule C that does not feel like a CSV import.

Competitive Landscape

You will get compared to TurboTax. Say it in the first sales call: they file from data the user typed. You file from books you already kept.

Intuit TurboTax — Category leader. Free for simple W-2-shaped returns; Self-Employed / Full Service runs to about $120+ per return including state, plus support upsells. Strength: brand, 44M-file muscle. Weakness: April-shaped UX, weak multi-platform payout ingestion, surprise fees after import. Not a year-round 1099 ledger.
H&R Block — About 15–20% of DIY online plus the retail safety blanket. Pricing comparable to TurboTax, often a bit lower on base SKUs, paid add-ons for humans. Strength: hybrid “someone will look at this.” Weakness: same import-then-file model.
ZenTax AI / TaxGenius AI and peer AI SaaS — The actual comps. Automated prep, deduction discovery, Stripe/Plaid connectors, chat UI. Typically $39–$69 per user per month or per-filing. Strength: they already pitch freelancers. Weakness: brand trust and a tendency to be “AI filing” without a boring, correct ledger. Beat them on source-to-line traceability and a transmitter acknowledgment, not another chat bubble.
Cash App Taxes — Free federal and state, Square ecosystem. Strength: price. Weakness: thin for multi-platform freelancers who do not live in Cash App. Your $29–$49 is dead if their whole life is Cash App payouts. Irrelevant if they have Stripe + PayPal + a bank.
Indirect: QuickBooks / Xero / FreshBooks and human CPAs. Books without transmit, or transmit without a productized $29 ledger. CPAs win complexity. They lose on $40K Schedule C work that should not cost four figures.

Your Opportunity

Incumbents will not productize “our April import is why you miss deductions.” Bookkeeping tools will not become EROs. Estimators will not e-file. Own the closed loop: payout platforms in, categorized ledger, user-reviewed Schedule C, licensed transmit out. Price in the $29–$49 band the AI SaaS comps already normalized. Win on three things they will not chase at indie scale: (1) source transaction visible on every form line, (2) year-round books that make April a review, (3) a hard v1 cutoff (sole prop, one state) so you do not drown in edge cases.

Business Model

Seasonal SaaS with a year-round pull. Free proves the ledger. File season captures the panicked. Always-on is the real business.

Free ($0) — One connected source, 90 days of categorization, read-only P and L, no e-file. Lead magnet for Reddit and YouTube.
File season ($49/month, typically January–April) — Full connections, deduction queue, Schedule C assembly, one federal + one state transmit. Matches the Ideabrowser frontend.
Always-on ($29/month or $399/year) — Year-round books, quarterly 1040-ES worksheets, included filing, accountant share link. Cheaper per month than File season because you want the twelve-month ledger. Annual at $399–$499 sits on the Ideabrowser middle offer.
Later, not v1: bookkeeping depth add-ons ($20–$100/month) and a white-label agency SKU ($25K/year in the ladder).

Unit Economics (illustrative)

a few dollars — Transmitter pass-through per accepted return, plus Plaid and LLM cost; keep combined variable cost well under the $29 Always-on price
about 75–85% — Gross margin on Always-on
$40–$80 — Target CAC via r/tax, YouTube walkthroughs, and Stripe/Plaid listings — not TurboTax SEM
four spikes a year — Quarterly deadlines reactivate File-season churners; Always-on should not need that crutch

Path to about $5K MRR: roughly 170 Always-on seats, or a mix (example: 80 Always-on + 90 File-season in Q1). Churn risk is April 16. The product that still shows a live P and L in June is the one that renews.

Recommended Tech Stack

Connectors, a correct form mapper, and a transmitter you do not have to become. Everything else is a dashboard.

Next.js 14 (App Router) + Vercel — Onboarding, review queue, return preview. Server Actions for categorization jobs; never ship bank tokens to the browser.
Plaid + Stripe + PayPal APIs — Income truth. Webhook signatures validated on an Edge route.
Supabase (Postgres + Auth) — users, connections, transactions, categories, rules, filings, transmitter_events. RLS per user. MFA on paid. Plaid tokens encrypted at rest.
Deterministic form engine — Your code maps categorized totals onto Schedule C lines and 1040-ES worksheets. Unit-test against IRS examples. The LLM does not add.
Claude — Vendor classification and “why this flag” copy only. Prompt-cache the user’s category list. Batch transactions.
Licensed e-file transmitter — TaxBandits-class API for 1040/Schedule C and 1099-NEC. Persist submission IDs and IRS acknowledgments. You prepare and send; the transmitter is the ERO pipe.
Stripe Billing + Resend + Vercel Cron — File season vs Always-on, January kickoff emails, quarterly worksheet reminders, Plaid re-pull so the ledger does not rot.

Put “not tax advice” on every filing screen and require a human-review checkbox that actually blocks transmit. If you cannot say that in the UI, do not ship e-file.

AI Prompts to Build This

Copy and paste these into Claude, Cursor, or your favorite AI tool.

1. Project Setup

Create a Next.js 14 App Router + TypeScript + Tailwind app called MyTaxGuy (freelancer tax filing bot).
 
Supabase tables: users (plan, filing_status, home_state); connections (provider plaid|stripe|paypal|drive); transactions (amount_cents, merchant, category, source_id, review_state); category_rules; filings (tax_year, status draft|user_reviewed|submitted|accepted|rejected, schedule_c_json, transmitter_submission_id); transmitter_events.
 
Auth: email+Google, MFA on paid. RLS so user_id = auth.uid(). Encrypt Plaid tokens at rest.
 
Stripe Billing: Free, File season $49/mo, Always-on $29/mo and $399/year.
 
Routes: /onboarding (Plaid Link + Stripe OAuth), /books (transaction queue), /review/:taxYear (source-to-line Schedule C), /file (submit + ack).
 
Copy on /review and /file: this is tax-prep software, not a CPA and not tax advice. Require an explicit “I reviewed these numbers” checkbox before transmit.

2. Ledger + Form Mapper (core)

Build the books-to-forms path. Do not let the LLM write form math.
 
1. Ingest Plaid, Stripe payouts, PayPal. Upsert by source_id. Amounts in cents.
2. Categorize: merchant rule first. Else batch 50 txs to Claude with the user’s category set (income, ads, software, contractor, meals, travel, home_office, owner_draw, ignore). Auto-apply confidence >= 0.85; else needs_user. Corrections write category_rules.
3. Monthly P and L from posted txs. Owner draws never hit expense. Meals flagged for confirm (do not auto-deduct 50%).
4. Pure-function form mapper, unit-tested: gross receipts, Schedule C expenses by line, net profit, SE tax at 15.3% (constant you update annually), 1040-ES remaining. Return JSON with supporting transaction IDs per line.
5. Claude may only write the explanation under each flagged line. If the model’s implied total disagrees with the mapper, show the mapper and ignore the model.

3. Transmitter + Landing

Integrate a licensed e-file transmitter (TaxBandits-style) and a landing page.
 
Transmit: POST schedule_c_json plus identity fields to sandbox; persist submission id and events; on reject show the error; never submit without user_reviewed = true and the disclaimer checkbox.
 
Landing for MyTaxGuy:
Hero: “Books that file.” Sub: “Connect Stripe and your bank. We keep the ledger all year and assemble Schedule C from those transactions. You review. A licensed transmitter e-files. Not a CPA. Not a chatbot guessing your income.”
Sections: five payout apps / one panicked April; 4 how-it-works steps; contrast vs TurboTax (import vs live books) and vs bookkeeping-only apps (P and L vs transmit); pricing Free / $49 season / $29 always-on; FAQ (we will not file K-1s, employees, rentals).
CTA: “Connect a test Stripe account.”
