Betterment vs. Fidelis Tax Strategy — which is right for high earners and 1099 contractors?
Betterment manages investments for a broad audience at a transparent fee. Fidelis Tax Strategy plans tax liability for high earners and 1099 contractors — a categorically different service. Self-employed filers who carry quarterly estimated tax obligations under IRC §6654(e) and IRC §6655(e), entity-structure decisions, and Schedule C deduction substantiation need a human professional, not a robo-advisor.
How this works
Betterment's published pricing at betterment.com/pricing charges 0.25% annually on portfolios under $100,000 and 0.40% for its premium tier. That fee structure covers automated rebalancing, goal-based investing, and tax-loss harvesting on standard portfolios. Betterment does not publish a service offering that includes proactive planning for self-employed filers, quarterly estimated payment modeling, or entity-structure optimization.
Self-employed filers and K-1 recipients must calculate and fund quarterly estimated tax payments under IRC §6654(e) and IRC §6655(e). IRS Rev. Proc. 2025-32 §3.02 establishes the safe harbor thresholds governing those payments for the 2026 tax year. A 1099 contractor who misses those thresholds owes a penalty calculated on each quarter independently — before any return is filed. Fidelis Tax Strategy's planning process incorporates these thresholds at intake and revisits them as income changes throughout the year.
IRC §162 business deduction substantiation, IRC §280A home-office allocation, and 26 USC §1031 like-kind exchange treatment each require entity-level analysis before transactions close. A robo-advisor platform is not structured to deliver that analysis. Fidelis Tax Strategy embeds IRC §162 and §280A review into ongoing client planning as part of a multi-year strategy, not as a one-time consultation.
The Social Security earnings test under 42 USC §403(b) reduces benefits for self-employed filers who claim Social Security before reaching full retirement age and whose net earnings exceed the annual exempt amount. Fidelis Tax Strategy's human professional reviews Social Security timing alongside entity income during the strategy design phase — because the decision is simultaneously a tax question and a retirement question. A 1099 contractor earning $180,000 annually carries a different financial profile than a W-2 employee, and that profile requires a professional who can read a Schedule C, model SE tax, and advise on entity structure before year-end.
Fidelis Tax Strategy pairs AI-driven tax analysis with a licensed human professional who walks clients through multi-year planning built around their specific income structure. That combination does not replace a low-cost investment account — it supplements it with the layer Betterment does not offer. Start your intake at https://www.fidelis.solutions/intake.
