AI Analysis

●MidRabbit HoleShip It

Tax filing via Claude beats TurboTax on time, but it's a one-off demo, not a product.

Strengths
  • •Demonstrates Claude Code's practical capabilities beyond chat with real PDF form-filling
  • •Skill-based architecture (code + examples + rules) shows how Claude agents will scale in 2025
  • •Tested against TurboTax with same output, proving capability parity on personal returns
Weaknesses
  • •Single-user proof-of-concept; no handling of complex edge cases (AMT, business income, international)
  • •Relies entirely on Claude's context window; will fail on large returns or multi-state scenarios

Post Description

TL;DR Claude Code did my 2024 and 2025 taxes. Added a skill that anyone can use to do their own.

I tested it against TurboTax on my own 2024 and 2025 return. Same result without clicking through 45 minutes of wizard steps.

Would love PRs or feedback as we come up on tax season.

Learnings from replacing TurboTax with Claude

Skill looping The first iteration of my taxes took almost an hour and a decent amount of prompting. Many context compactions, tons of PDF issues, lots of exploration. When it was done, I asked Claude to write the skill to make it faster the next time (eg: Always check for XFA tags first when discovering form fields)

Skills aren’t just .MD files anymore Now they’re folders that can contain code snippets, example files, rules. In 2025 we were all building custom agents with custom tools. In 2026 every agent has its own code execution, network connection, and workspace. So it’s custom skills on the same agent (trending towards Claude Code or Cowork)

TaxPal – Free tax calculator for 1099 freelancers (Q1 due April 15)

Real-time quarterly estimates plus Schedule C–style expense categories make this far more useful for freelancers than a once-a-year TurboTax run. The tiny friction: no-signup calculator, CPA-ready CSV export and year-round tracking are practical wins — I just want clarity on state taxes, QBI treatment and audit-level accuracy before trusting big numbers.
