Estimate a planning tax reserve from taxable profit, an assumed tax rate, social contributions, prior balances, and money already reserved.
By Solopreneurship WikiReviewed September 2026
Wiki note: Tax money is a liability, not spendable operating cash; keep it separate and update the estimate as profit changes.
This educational calculator turns an assumed effective tax rate into a reserve target and shows the remaining amount to set aside. It deliberately keeps the rate visible because tax rules depend on jurisdiction and legal form.

Calculate your result
Change the example assumptions to match your situation. Use consistent units and the same currency throughout.
Calculations run in your browser. Nothing is submitted.
Your result will appear here.
Enter your assumptions and select “Calculate result.”
Use source data where possible, record the date of your assumptions, and keep all monetary inputs in the selected currency. A precise-looking answer is only as reliable as the inputs behind it.
How to interpret the result
Use the result to plan transfers, then replace assumptions with calculations from a qualified local professional. Recalculate after material revenue, expense, legal-structure, or residency changes.
Stress-test the decision
Run a conservative case, an expected case, and an optimistic case. Change one important assumption at a time so you can see what actually drives the answer. Define the action you will take if the conservative case occurs.
Worked example
A business expects 70,000 of taxable profit, uses a 24% planning rate, anticipates 4,000 in contributions and a 1,000 prior shortfall, and already holds 9,000 in its tax account.
Replace every example value with evidence from your own accounts, time records, quotes, contracts, or customer data. Save the result alongside those sources so it can be reviewed later.
