General Questions
Core questions about monthly tax reserves.
What is a monthly tax reserve?
It is money set aside from business profit to help cover future income tax and profit-based contribution liabilities.
Who can use this calculator?
It can help self-employed people, contractors, freelancers, and business owners create a simple monthly reserve estimate.
Is the result tax advice?
No. The result is a planning estimate based on the figures and rates entered.
Inputs and Calculation
How revenue, expenses, rates, and buffers are used.
Should revenue include business expenses?
Enter revenue before business expenses. The calculator subtracts the expenses you enter to estimate profit.
What expenses should be entered?
Use your estimated allowable business expenses. Personal spending should not be included as a business expense.
What is the combined estimated rate?
It is the income tax rate plus the other profit-based contribution rate entered in the calculator.
Why is there an extra reserve buffer?
It adds a contingency amount for uncertainty, changing profit, incomplete records, or later adjustments.
Results and Accuracy
How to interpret the reserve and projection outputs.
Does the calculator calculate an actual tax bill?
No. It does not account for every rule, threshold, credit, relief, deduction, or payment arrangement that may apply.
Why might my actual liability differ from the estimate?
Actual results can differ because income, deductions, rates, credits, losses, and local rules may change the final calculation.
Is the annual reserve the same as annual tax due?
No. It is twelve times the monthly estimate and is most useful when monthly profit and rates remain broadly similar.
What does profit after reserve mean?
It is estimated taxable profit less the recommended tax reserve. It is not necessarily the cash available for all other spending or business obligations.
Related Use Cases
Questions about different business situations.
Does this include sales tax or VAT?
No. The calculator is for profit-based taxes and contributions. Sales taxes collected from customers are generally tracked separately.
Can I use it when income varies each month?
Yes. Updating the monthly revenue and expense inputs as conditions change can provide a more current estimate.
Can a business with a monthly loss use the calculator?
Yes. If expenses exceed revenue, estimated taxable profit and the resulting reserve are shown as zero.
Should I calculate a tax reserve from revenue or profit?
For profit-based taxes, use estimated profit: revenue less allowable business expenses.
