Cyprus Property VAT: 5% or 19%
The 5% first-home rate covers 130 m² and €350,000 — but cross 190 m² or €475,000 and you lose it entirely, a €49,000 swing. Plus the 2027 deadline.

Madeira & Azores VAT Rates
Portugal has three IVA schedules, not one. Mainland 23/13/6%, Madeira 22/12/4%, Azores 16/9/4% — and the Artigo 6.º rule that decides which applies.

How to Get a Sales Tax Refund
The seller refunds it first, the state second. Deadlines, claim forms, the assignment of refund rights, the visitor schemes that really exist, and how businesses claim.

Online Sales Tax Explained
Why internet orders are taxed, which address sets the rate, who collects it, when you owe use tax yourself, and what happens on orders from abroad.

Every state-level change with its effective date — Illinois' grocery handover, Washington's services expansion, Chicago's transit increase, and more.

Why local changes land on quarter days, what notice states must give, and which date governs a sale that straddles a change.

Transit, stadium and cultural districts — MCTD, RTA, RTD, Sound Transit — and why their voted borders break ZIP-level lookups.

The five NOMAD states with none, the lowest-rate states that do tax, and what each low-tax state charges instead.

Amazon collects on marketplace orders, but FBA inventory creates physical nexus with no threshold — and never covers your own store.

Are Services Taxable? The 2026 State-by-State Picture for Service Businesses
Goods are taxable by default, services by exception — and the exceptions are wide. Four categories, and the invoice trap.

Bundled Products and the True Object Test
One undivided price can make an entire invoice taxable, including the part that would have been exempt alone.

Car and Vehicle Sales Tax by State
Vehicle tax follows where you register, not where you buy. Trade-in credit is where the real money moves.

Digital Products Sales Tax

The platform collects at checkout. Your thresholds, your own site, your market stall and your 1099-K gap are still yours.

EU ViDA Explained
Three pillars staged across the decade, ending with structured e-invoicing and near-real-time reporting on intra-EU trade.

GST/HST for Non-Resident and Digital Businesses Selling Into Canada
Register once past CAD $30,000. The simplified regime is easier to file and gives up input tax credits entirely.

How to Close a Sales Tax Account Without Triggering an Audit
Stopping sales does not stop the obligation. A dormant registration keeps demanding returns and accruing penalties on nothing.

Filing through software is the visible half. The digital links rule is the half that fails inspections.

Contractors usually pay tax on materials and charge none on the improvement — the inverse of retail logic.

Sales Tax on Gift Cards, Store Credit and Loyalty Points
A gift card is a payment method, not a purchase. Everything interesting happens at redemption.

Sales Tax Penalties and Interest
Two penalties charged separately, interest on top, and personal liability that survives the company.

Shopify Sales Tax Setup
Shopify calculates where you tell it to. It will not decide your nexus, classify your products, or file anything.

Sales tax plus a local lodging tax. Platforms collect some of it, rarely all, and never register you.

UK VAT Registration Threshold
Two tests, not one. The rolling twelve months is continuous, and the forward-look test can catch you before the income arrives.

Arizona taxes the seller, not the buyer. Business classification sets the rate, and cities set their own tax base independently of the state.

California Sales Tax by ZIP Code
California district taxes stack on a statewide base and follow city and district lines, so one ZIP can hold several correct rates.

About half of US states tax delivery charges. The three-tier framework, the handling trap that costs sellers thousands, and the mixed-shipment allocation math.

Marketplace Facilitator Laws: Who Actually Collects Your Sales Tax
Amazon and Etsy collect the tax — but registration, nexus tracking and filing never transferred. Why marketplace sales still count toward your thresholds.

Origin vs Destination Sales Tax: Which Rate Do You Charge?
Sourcing decides whose address sets the rate. The origin-based states, the remote-seller override, and California's hybrid rule.

How states assign your filing frequency, why it changes without warning, and why the returns with no tax on them generate most of the penalties.

Sales Tax Tables
Bracket schedules explained: how states convert a sale amount straight into cents of tax, and why the chart can differ from multiplying by the rate.

Streamlined Sales Tax
One registration across member states and state-funded compliance software — plus the filing obligation every selected state creates.

Use Tax vs Sales Tax: The Tax Almost Nobody Files
Same rate, same base, paid by the buyer instead of the seller. The four business triggers, and why auditors test it first.

VAT Reverse Charge Explained: Why Your EU Invoice Says €0 VAT
The reverse charge moves VAT to the buyer on cross-border B2B supplies. Both sides of the entry, VIES validation, and when it stops being cash-neutral.

Voluntary Disclosure Agreements
Capped look-back, waived penalties and an anonymous approach — and why state contact closes the option.

What Triggers a Sales Tax Audit? The Real Red Flags
States data-match your returns against processors, marketplaces and federal filings. The nine signals that surface a business.

GST/HST Compliance for Canadian Businesses (2026)
Beyond the rate: zero-rated vs tax-exempt supplies, when the CRA Quick Method beats tracking input tax credits, and the non-resident digital vendor rules.

Tip on the pre-tax subtotal or the total? The etiquette answer, the real dollar difference, and the math.
