Tax Formula

Tax = Amount × (Tax Rate / 100) • Total = Amount + Tax

100 × (8.5 / 100) = $8.5 tax • Total: $108.5

Sales Tax & VAT Calculator — Add or Remove Tax from Any Amount

Enter a pre-tax amount and a tax rate (or pick a preset: 5/6/7/7.5/8/8.5/9/9.5/10% for US sales tax tiers, plus 21% for Spain/Belgium/Latvia VAT) and the page returns the tax amount and the gross total. Toggle to reverse mode to extract the tax FROM a gross figure (useful when the receipt only shows the total or when an invoice quotes tax-inclusive). Useful for checking a sales tax line on a US store receipt, separating VAT from a European invoice for accounting, computing the after-tax cost of something while traveling, sanity-checking a freelance invoice you're sending to an EU client, or doing back-of-envelope import-duty math.

About this tool

Add-tax math: tax = pre_tax × (rate / 100), total = pre_tax + tax. Remove-tax math (reverse): pre_tax = gross / (1 + rate/100), tax = gross − pre_tax. Reverse mode is the trickier one because dividing by (1 + rate/100) reaches a different number than just multiplying by (1 − rate/100) — a $107 gross at 7% tax is $100 pre-tax + $7 tax, not $99.51. The page handles this correctly with the proper division. Common reference rates: US sales tax varies by state and locality (no federal sales tax) — California 7.25% base, often 8-10% with city/county add-ons, Tennessee up to 9.75%, Texas 8.25%, while Oregon, Montana, New Hampshire, Delaware, and Alaska have NO state sales tax (some Alaskan cities have local sales tax); EU VAT typical rates Spain 21%, France 20%, Germany 19%, Italy 22%, Netherlands 21%, UK 20%, plus reduced rates for food (10% Spain, 5.5% France) and zero rates for some books/medicine; Japan consumption tax 10% (8% reduced for food); Australia GST 10%; Canada GST 5% federal + provincial 0-10%. The tool intentionally does NOT compute progressive income tax — that needs jurisdiction-specific brackets and a different tool. Estimate only — not financial or tax advice; consult a qualified accountant or tax advisor before filing returns or making decisions based on these figures.

Frequently asked questions

What's the difference between add-tax and reverse-extract math?

Add-tax math: tax = pre × (rate/100); total = pre + tax. Reverse-extract math: pre = gross / (1 + rate/100); tax = gross − pre. The reverse mode is the trickier one because dividing by (1 + rate/100) reaches a different number than just multiplying by (1 − rate/100) — a $107 gross at 7% tax extracts to $100.00 pre-tax + $7.00 tax, NOT $99.51 pre-tax. The naïve "subtract 7%" approach gives 107 × 0.93 = $99.51 which understates the pre-tax amount by $0.49. The same trap applies to VAT extraction in EU contexts. The page handles both directions correctly with the proper division for reverse mode.

How does US sales tax differ from EU VAT structurally?

The US has no federal sales tax — sales tax is a state-and-locality construct, with rates varying widely (California 7.25% state base, often 8-10% with city/county add-ons; Tennessee combined up to 9.75%; Texas 8.25%). Five states have NO statewide sales tax — the NOMAD states (New Hampshire, Oregon, Montana, Alaska, Delaware), though Alaska and Montana allow LOCAL sales taxes (Alaska up to 7.85%) and Delaware levies a gross receipts tax. Since South Dakota v. Wayfair, Inc. 585 U.S. 162 (decided 21 June 2018), states require remote sellers to collect sales tax once they cross economic-nexus thresholds (South Dakota's were $100,000 in sales OR 200 transactions per year). EU VAT, by contrast, is a harmonised value-added-tax system (Directive 2006/112/EC) with a 15% standard-rate floor across all 27 Member States.

What are typical VAT rates across major EU economies?

EU VAT Directive 2006/112/EC Article 97 sets a 15% standard rate floor (introduced by Council Directive 92/77/EEC of 19 October 1992; made permanent by Council Directive (EU) 2018/912 of 22 June 2018). Standard rates as of 2026: Spain 21%, France 20%, Germany 19%, Italy 22%, Netherlands 21%, Hungary 27% (highest in EU), UK 20% (post-Brexit, separate from EU regime). Reduced rates (minimum 5% per Article 98 + Annex III): Spain 10% on non-staple food + 4% super-reduced on staples, France 10% on most food + 5.5% on books and certain basic foodstuffs, Germany 7% on food + books + cultural events. Super-reduced and zero rates retained for historical reasons in specific Member States: UK zero-rates children's clothes + books + most basic foods + public transport; Ireland zero-rates basic foods + children's clothes; Spain super-reduced 4% on staple foods + books.

What about Japan, Australia, Canada consumption taxes?

Japan consumption tax (消費税 Sho-hi-zei) 10% standard since 1 October 2019 (raised from 8%); 8% reduced rate retained for food + non-alcoholic beverages + newspaper subscriptions per the Consumption Tax Act. Australia GST (Goods and Services Tax) 10% since 1 July 2000 under A New Tax System (Goods and Services Tax) Act 1999 — fewer exemptions than EU VAT (most basic foods GST-free; education + health GST-free). Canada GST 5% federal, plus provincial PST 0-10% or harmonised HST in 5 provinces (Ontario 13%, Nova Scotia 14% since 1 April 2025, New Brunswick / Newfoundland & Labrador / PEI 15%). New Zealand GST 15%, the highest in OECD without reduced rates. Per OECD Consumption Tax Trends 2024, average OECD-wide standard VAT/GST rate is 19.3% (2024 figure).

Does this compute progressive income tax?

No — this calculator handles flat-rate consumption tax (sales tax, VAT, GST) which applies a single percentage to a transaction value. Progressive income tax requires jurisdiction-specific bracket structures (US federal 7 brackets 10-37% under TCJA + state brackets; UK 4 bands 0-45%; Spain national + autonomous-community variation 19-47%; Germany linear progression 14-45%) plus deductions, allowances, credits, and filing-status nuances that change annually. Use cases for this calculator: checking a sales-tax line on a US store receipt, separating VAT from a European invoice for accounting, computing the after-tax cost while travelling, sanity-checking a freelance invoice quoted to an EU client, or back-of-envelope import-duty math. For income tax, use a jurisdiction-specific tool with the current year's brackets.
