Capabilities

Everything the self-employed need.

Irregular income smoothing

Stackr averages the last 12 months, spots volatility, and warns when runway is getting short.

Quarterly tax estimates

Real-time estimate of what you owe. Countdown to the next deadline. Reserve percentage updated every sync.

Business expense tracking

Every deductible expense flagged automatically. See estimated tax savings from deductions at a glance.

Dedicated tax reserve

Link a savings account as your tax reserve. Stackr tracks whether it's fully funded against your actual liability.

Self-employed retirement

SEP-IRA, Solo 401(k) — Stackr shows how much you can contribute and what it saves in taxes at your effective rate.

Coach that gets freelancers

"Is my income trending down?" "What's my tax exposure this year?" — answered from your actual transaction data.

Stop guessing what you owe.

Connect your business and personal accounts. Stackr separates the signal from the noise.
