**Don't ignore it: find out which letter it is, note its deadline, and answer in time.** Most letters give you a few working days only, counted from the day after you received it.

## The usual letters

- **Requerimiento:** the tax office asks for documents, an explanation or a missing return. At least **10 working days**, the number the letter gives. Ignoring it costs a fine of €150, then €300, then €600.
- **Propuesta de liquidación:** a proposed new figure for your tax, nothing to pay yet. **10 to 15 working days** to object (alegaciones).
- **Liquidación provisional:** an assessment to pay. Received from the 1st to the 15th of a month: pay by the 20th of the next month; from the 16th: by the 5th of the month after. One month to appeal.
- **Procedimiento sancionador:** a proposed fine. **15 working days** to answer. Agreeing cuts it by 30%, then paying on time without appealing by a further 40%.
- **Providencia de apremio:** a debt not paid in time, now with a surcharge: 10% if you pay by its deadline, 20% after, and then the tax office seizes.

## Good to know

- Working days: Saturdays, Sundays and Spanish public holidays don't count. A deadline falling on one moves to the next working day.
- Every letter carries a **CSV**, a 16-character code at the foot of the first page: typed into the Agencia Tributaria's online office, it brings up the original.
