Combined ranking
- 1GPT #2Claude #1Gemini #1Grok #1
The most polished guided interview in the category, broadest form coverage (self-employed, investments, rental, multi-state), seamless import of W-2s/1099s/prior returns and crypto, plus live expert review (TurboTax Live) and audit support; handles the most complex situations with the least user confusion.
To stay #1 Slash its premium pricing and stop the aggressive upsell/"free" bait-and-switch that pushes users into paid tiers.
- 2GPT #1Claude #3Gemini #2Grok #3
Best overall mix of guided filing, broad form coverage, transparent help options, strong DIY software, and access to real tax pros or offices when a return gets complicated
To rank higher Lower paid-tier and state-filing prices
- 3GPT #3Claude #2Gemini #3Grok #2
Free federal filing for virtually every form including self-employment, investments, and rental income, with only a low flat fee for state — by far the best value for complex returns; accurate, no-gimmick, and supports prior-year imports.
To rank higher Modernize the dated UI and add stronger automated document import (auto W-2/1099 photo/PDF capture) to match the big players' onboarding speed.
- 4GPT #5Claude #4Gemini #4Grok #4
Low flat pricing across tiers (Classic covers all major forms including self-employment) makes it the best budget pick for confident filers; fast, lightweight, and includes free phone/email support even at lower tiers.

- 5GPT #4Claude —Gemini —Grok #5
Solid balance of price, form coverage, accuracy tools, and support for homeowners, investors, landlords, and self-employed filers without TurboTax-level cost

Genuinely 100% free for both federal AND state with no tier upsells, covering most common situations including some self-employment and investment income — unbeatable for the price.
