  3. Read the split instantly. You get the net amount, the exact tax, and the gross total — ready to quote, invoice, or check a receipt against.

Why getting the New Jersey split right matters

Quoting a price without the tax — or adding tax twice — is how invoices turn into arguments. This calculator keeps the maths honest: the net, the tax and the total, split out in plain sight. When the numbers are right, drop them straight into the free invoice generator — flat tax, per-line tax and GST modes are built in.
