VAT to offset (IVA a compensar)
When you paid more VAT on expenses than you charged on invoices in a quarter, the Spanish tax office does not refund it straight away: you carry it forward to the next quarters.

When it happens
It is common when you start (you buy equipment and invoice little), in slow seasons or after a large investment.
How it is used
It is subtracted from the result of your next form 303. Example: you have €400 to offset in Q1 and would owe €1,000 in Q2: you pay only €600.
You have four years to use it. If there is still a balance in the last quarter of the year, you can keep carrying it forward or ask for a refund.
The refund
You request it on the fourth-quarter form 303. The tax office has six months to pay; after that, it owes you interest. For monthly refunds, you can join the monthly refund register (REDEME), but then you file VAT every month.
