Tax Codes

Tax in Horizon Finance Core is deliberately simple: you define tax codes with rates, apply them to invoice lines, and the tax amount is calculated when the invoice posts. Deterministic pick-and-multiply — you always know exactly what was charged and why.

Create a Tax Code

1. Open Tax Codes (under Tax in the Finance sidebar) and create one: a name your team will recognize and the rate it carries.

2. Create one code per rate you charge — a standard rate, a reduced rate, a zero rate for exempt work.

Apply It to an Invoice

1. On an invoice line, pick the tax code that applies.

2. When the invoice posts, the tax calculates from the code’s rate and posts with the rest of the entry — the invoice total, the tax amount, and the ledger all agree.

Note

Tax codes apply to your sales documents. Horizon doesn’t file returns or determine which jurisdictions you owe — your accountant reads the numbers straight from your posted documents, which is exactly where they should come from.
