Tax Set turns every payment, expense, and deduction into one clear reserve figure — calculated by a deterministic tax engine, explained in plain language, and never hidden behind a manual "Calculate" button.
Tax Set is built by SoluLab for independent workers, freelancers, and gig-economy earners who don't have an employer withholding taxes on their behalf. Instead of a once-a-quarter guessing game, Tax Set keeps one reserve-first number in front of you at all times — grounded in a deterministic tax engine, not a black-box estimate.
Our thesis is simple: the number you see should always be explainable. Every change to your reserve is traced back to the specific transactions and IRS thresholds behind it, so you always know the "why," not just the "what."
Every core screen exists to keep one number current, explained, and trustworthy.
A single, always-current reserve number that recalculates automatically on every new transaction — never a manual "Calculate" step.
Every meaningful change cites the specific transactions and IRS rule behind it — never a generic "your income changed" message.
High-confidence transactions are classified silently; lower-confidence ones enter a review queue with a visible confidence score.
A quarter-end liability projection based on your real recorded activity, always labeled a projection with a confidence level.
A persistent countdown, safe-harbor progress, and a transparent shortfall amount — always two distinct indicators, never guesswork.
Correct any figure with a reason on record — your override is always shown alongside the deterministic engine's own value.
An append-only, reverse-chronological audit trail of every reserve-changing event.
