what tax is this

It is hard to see what letter this is, but on the downside it puts in point 2: Get more information in your 'ayuntamiento', which is the townhall from where you live. The best is to ask there what this is about.

Could be your non-resident tax for 2018, but on the upside it gives you a web address to consult instead of going to the ayuntamiento.

There's a blue tab for Consultar la informacion de avisos en carta.  Enter your NIE (it says NIF, but hopefully NIE works too), postcode and the number 547117 from your letter.
