These focused sections provide arithmetic presets and practical limitations for selected jurisdictions. Use the official source link in each card to verify current rates and transaction rules.
Add or remove UK VAT using the standard 20%, reduced 5% or zero rate. Tax treatment depends on the exact goods, services and date of supply.
Important: Most taxable supplies use 20%, but reduced, zero-rated and exempt categories follow detailed HMRC rules.
Open official rate reference ↗Calculate Indian GST with common slabs and choose an intra-state CGST/SGST split or an interstate IGST presentation.
Important: Classification, place of supply, cess and special rates are not inferred. Confirm the applicable notification and HSN/SAC treatment.
Open official rate reference ↗Add Australian GST or extract the GST included in a price. The standard rate is 10%, which is one-eleventh of a GST-inclusive price.
Important: Some supplies are GST-free, input taxed or subject to special rules. The preset is arithmetic guidance only.
Open official rate reference ↗Calculate the 5% federal GST used in non-participating provinces and territories, before any separate provincial sales tax.
Important: Place-of-supply and product rules determine whether GST, HST, PST, QST or a zero-rated treatment applies.
Open official rate reference ↗Add or remove Ontario HST using the 13% harmonized rate for ordinary taxable supplies.
Important: Rebates, point-of-sale relief and zero-rated or exempt supplies are not classified automatically.
Open official rate reference ↗Calculate the common British Columbia combination of 5% GST and 7% PST, with a separate component breakdown.

Open official rate reference ↗Add or remove New Zealand GST at 15%, including the familiar 3/23 extraction from a GST-inclusive amount.
Important: Zero-rating and exempt treatment depend on the transaction. The tool does not determine legal classification.
Open official rate reference ↗Calculate Singapore GST at the current 9% standard rate or remove GST from an inclusive price.
Important: The calculator does not decide whether a supply is standard-rated, zero-rated, exempt or outside scope.
Open official rate reference ↗Add or remove UAE VAT using the standard 5% rate and produce a clean taxable amount, VAT and total breakdown.
Important: Zero-rated, exempt and designated-zone treatment requires transaction-specific review.
Open official rate reference ↗Start with California’s 7.25% statewide rate and add the applicable district rate manually for the delivery or use location.
Important: California combined rates vary by city, county and district. Verify the current address-specific rate before invoicing.
Open official rate reference ↗Calculate Texas state sales tax at 6.25% and add local tax up to the official 2% maximum for an 8.25% combined ceiling.
Important: The correct local rate depends on the taxing jurisdictions and sourcing rules for the transaction.
Open official rate reference ↗Start with New York’s 4% state rate and enter the city, county, school-district or MCTD portion that applies.
Important: Combined rates vary by jurisdiction and often follow the delivery location. Confirm the current locality rate.
Open official rate reference ↗Calculate Illinois state sales tax for general merchandise or the reduced state rate for qualifying food, drugs and medical appliances, then add local tax manually.
Important: Local and special-district taxes can materially change the combined rate. Use the official address-based finder for filing.
Open official rate reference ↗This calculator handles the core arithmetic shared by VAT, GST and retail sales tax systems: adding tax to a net amount and extracting included tax from a gross amount. The selected profile controls the default rate, currency and component presentation, while custom-rate and local-rate fields keep the engine useful when a jurisdiction has a different combined rate.
VAT and GST are generally value-added systems collected through stages of the supply chain, while U.S. sales tax is generally imposed at retail and often varies by state and local jurisdiction. The arithmetic can look similar, but legal taxability, credits, exemptions, sourcing and reporting are not interchangeable.
Select a country, Canadian province or U.S. state profile, then choose the applicable preset rate or enter a custom rate.
Use Add tax for a tax-exclusive amount or Remove included tax when the entered amount already contains VAT, GST or sales tax.
Enter the amount, quantity, discount and optional shipping, then choose whether shipping is taxable.
Review the net amount, tax components, effective rate and final total. India, Canadian split-tax and U.S. local-rate profiles show component details.
Use the invoice tab for multiple tax-exclusive line items, then copy, print or download the TXT report and CSV line-item schedule.
It adds tax to a tax-exclusive amount, removes tax from a tax-inclusive amount, separates tax components, calculates invoice line items and provides reference presets for selected countries, Canadian provinces and U.S. states.
Yes. Choose Remove included tax. The calculator divides the taxable gross amount by one plus the combined tax rate, then displays the net amount and extracted tax.
Choose Add tax, enter the tax-exclusive amount and select or enter the applicable rate. The tax is the taxable net amount multiplied by the rate.
Yes. Enable the custom-rate field or select a profile option that allows local tax. Rates from 0% to 100% are accepted for arithmetic flexibility.
No. Presets were reviewed on the date shown on the page, but tax rates, temporary measures and classification rules can change. Verify the current official source before invoicing or filing.
No. It performs arithmetic only. Exemptions, zero-rating, place-of-supply rules, tax holidays, product categories and registration status require legal and official guidance.
A tax-exclusive price does not include tax, so tax is added. A tax-inclusive price already contains tax, so the net and tax portions must be extracted.
For a combined rate r, the net amount is gross divided by 1 plus r, and tax is gross minus net. For example, 20% VAT is one-sixth of a VAT-inclusive total.
Yes. The amount is treated as a per-item value and multiplied by quantity before the percentage discount is applied.
Yes. The percentage discount reduces the entered item amount before tax is calculated or extracted.
Yes. Enter shipping and select whether it follows the selected tax rate. When tax is removed, taxable shipping follows the same inclusive basis as the item amount.
For intra-state presentation, the selected GST rate is divided equally into CGST and SGST. For interstate presentation, the full selected rate is shown as IGST. The tool does not determine place of supply.
No. Cess and special product rates are not calculated automatically. Add a custom rate only after confirming the correct legal treatment.
The combined preset shows 5% GST and 7% PST on the same taxable base. Because the two systems can have different exemptions, confirm that both apply before using the combined result.
The combined preset uses 5% GST and 9.975% QST, producing 14.975% when both apply to the same taxable amount.
The preset uses 14%, effective from 1 April 2025. Historical transactions may require a different rate and transition rules.
No. The state profiles provide a state or statewide base reference. Enter the verified local or district rate manually because combined rates depend on location and sourcing rules.
The preset starts at the 7.25% statewide rate. Applicable district taxes must be added manually using the current address-specific official rate.
The preset starts at the 6.25% state rate. Local jurisdictions can add up to 2%, for a maximum combined rate of 8.25%.
The preset starts at the 4% state rate. City, county, school-district and possible MCTD rates must be added based on the applicable jurisdiction.
The profile includes 6.25% for general merchandise and 1% for qualifying food, drugs and medical appliances, before applicable local taxes.
Yes. Select a 0% option or enter a custom rate of zero. Zero-rated and exempt transactions can have different reporting and input-credit consequences, which this tool does not determine.
You can choose standard rounding, round up or round down and select zero to four decimal places. Invoice mode rounds each line and then totals the rounded lines.
Rounding each component or invoice line can create small differences. The calculator adjusts the final displayed component so the rounded components equal the rounded total tax.
Yes. Add up to 30 tax-exclusive line items with descriptions, quantities, prices, discounts and taxable status. All rows use the currently selected profile and rate.
Yes. Download the transaction report as TXT and the invoice line-item schedule as CSV. Download names begin with correctioncopy.com_.
Yes. Use Print Result and select a PDF destination in the browser print dialog when supported.
No page-specific request sends the entered amounts or invoice details. Calculations and exports run in the browser.
No tool-specific account, database or persistent browser storage is used. Values remain in the current page session unless the browser itself restores form state.
No. It creates arithmetic summaries and a line-item CSV, not a legally compliant tax invoice, return, filing or accounting record.
Yes. Controls stack on small screens, tables can be scrolled horizontally when necessary and primary actions remain touch-friendly.
Confirm the applicable place-of-supply or sourcing rules with the relevant authority or a qualified adviser, then enter the verified combined rate or components.
