What it is
IVA (Mexico's value added tax) and ISH (the state lodging tax) are not filed together, so they shouldn't live in the same account. In Conceptos y sus cuentas (concepts and their accounts), below the concepts table, the Impuestos y sus cuentas (taxes and their accounts) table lists every active tax at your hotel, with its Tasa (rate, or “Monto fijo” for a fixed amount) and the Cuenta (account) it goes to.
Any tax you leave on “La cuenta general de trasladados” (the general output tax account) lands in the account with the impuestos trasladados role (in the base chart, 208-01 IVA trasladado), as it always has.
How the daily journal entry uses it
On each line of the signed sheet that carries its tax broken down by tax, and only if that breakdown adds up exactly to the line's tax, every peso goes to its own tax's account. If there is no breakdown, or it doesn't add up exactly, the whole tax goes to the general account. It is never prorated: inventing a breakdown would be worse than not having one.
For example, an extra bed of 300.00 MXN with 16% IVA (48.00 MXN) and 3% ISH (9.00 MXN) posts like this: 357.00 MXN debited to the guest ledger and, as credits, 300.00 MXN to its revenue account, 48.00 MXN to the IVA account and 9.00 MXN to the ISH account.
Fixed charges posted with the night, such as an extra bed or breakfast, carry the breakdown. Room revenue, package components included in the rate, and days signed before this feature existed arrive with the tax as a single amount and go entirely to the general account. Folio charges entered as a lump amount carry no separate tax.
Step by step
- Have an account for each tax in the chart. For ISH, the base chart includes 213-01 Impuesto sobre hospedaje por pagar (lodging tax payable), but it comes with its own role (impuesto hospedaje), and the table won't accept accounts that already have one: edit it, clear Papel en la póliza (role) and save. No process uses that role.
- Open Conceptos y sus cuentas and scroll down to Impuestos y sus cuentas.
- Under Cuenta, pick the tax's account. It saves as soon as you pick it, and the account gets a role that starts with “impuesto:”.
- To undo it, pick “La cuenta general de trasladados”.
What can go wrong
- “La cuenta … ya tiene el papel…” (the account already has a role): you picked an account with another role. Pick a different one or remove that role first.
- The table doesn't appear: your hotel has no active taxes in Settings → Taxes & Charges.
- One tax, one account. When you pick a new one, the previous one is released.
- Signed days don't change. The assignment applies to journal entries generated afterwards. See Why a signed day is never recalculated.
- The general account is never redundant. Even if every tax has its own, lines without a breakdown need it: that's why the impuestos trasladados role is required. See The tax went to the general account.
