Sales Tax & Local Tax Split Calculator
Determine total gross price and extract tax components instantly. Supports custom state and local/county sales tax rates.
Sales Tax Summary
Your sales tax breakdown and calculations simplified:
Net Base Price
The price of the item before tax is applied.
State Tax Amount
The portion of tax directed to the state level.
Local Tax Amount
The portion of tax directed to city/county jurisdictions.
How is it calculated?
Total\ Tax = Base \times \frac{State\ Rate + Local\ Rate}{100} \quad | \quad Base = Gross \times \frac{100}{100 + State\ Rate + Local\ Rate}For Exclusive tax, multiply the base price by the combined tax rates. For Inclusive tax, divide the gross price by 1 plus the combined decimal tax rate to find the pre-tax base, and calculate the difference as total tax.
Worked Examples
Adding 6% State and 2% Local Tax to $1,000 Base price
Total Combined rate is 8%. Sales Tax = $1,000 * 8% = $80. Total price is $1,080, where state tax is $60 and local tax is $20.
Extracting 8% Combined Tax from $1,080 Invoice price
Base Price = $1,080 / (1 + 0.08) = $1,000. Total tax is $80, which is divided into $60 state tax and $20 local tax.
Income Tax Regime Comparison Guide (Old vs. New Slab)
The Indian Income Tax Structure
In India, individual taxpayers can choose between two main tax structures to calculate their annual income tax liability: the Old Tax Regime and the New Tax Regime. Choosing the right regime is essential to maximize your take-home pay and optimize tax savings.
The Old Regime features higher tax rates but allows a wide range of deductions and exemptions (such as Section 80C, 80D, HRA, and home loan interest). The New Regime offers simplified, lower tax slab rates but withdraws almost all exemptions.
How to Compare Regimes Using the Tax Calculator
To compare your tax liability under both regimes, enter your gross annual salary, other income sources (like interest or capital gains), and the tax deductions you plan to claim (80C investments, health insurance, etc.).
The calculator will compute your taxable income for both regimes, apply the standard deductions, map your income to the respective slab rates, and show a clear side-by-side comparison of the tax payable. This helps you identify which regime saves you more money.
The Mathematical Logic of Progressive Tax Slabs
Tax is calculated progressively across income slabs, rather than applying a single rate to your entire income. The formula is:
Tax = Sum of (Income in Slab * Slab Rate) + 4% Health & Education Cess
Under the New Regime (as updated in recent budgets), no tax is payable for taxable income up to ₹7 Lakhs due to rebate provisions under Section 87A. For higher incomes, standard tax slabs of 5%, 10%, 15%, 20%, and 30% are applied incrementally after deducting the flat standard deduction of ₹75,000.
Old vs. New Regime: The Break-Even Point
The choice depends on your investment levels. If your total tax-deductible investments (80C, HRA, 80D, Home Loan interest) exceed ₹3.75 Lakhs, the Old Regime is generally cheaper.
If your investments are low (e.g., you do not want to lock up money in tax-saving schemes), the New Regime is more beneficial due to its lower slab rates. This tool computes your unique break-even investment point.
