Every price on idleakcheck.com — $14.99/mo, $79.99/mo, $1,499/mo, the $10.99 one-time — already includes any applicable sales tax, VAT, or GST for your jurisdiction. The receipt confirms this with a “Tax included” line; you won’t see tax added on top.
This means a $14.99 subscription costs you exactly $14.99, regardless of where you live. Behind the scenes, we settle the tax with the relevant authority. You can download a tax-itemized version of any invoice from the Stripe Customer Portal if your accounting software needs it.
