How this works and common questions
About this tool
Tax on the sales you type, minus tax on the purchases you type. A positive result is an amount owing. A negative result is a refund. A simple estimate, not advice. Nothing you type leaves this device.
How it works
Tax collected is taxable sales times the sales rate you type, rounded half up to the cent. Credits are purchases times the credit rate you type, the same way. The net is collected minus credits. 10000.00 at 5 percent is 500.00. 2000.00 at 5 percent is 100.00. The amount owing is 400.00.
Rules
You type both rates. This page does not look up a rate. A credit larger than the tax collected is a refund. Verify with the official source. A simple estimate, not advice.
