If you disagree with a Welsh Revenue Authority tax decision

You can ask us to review some penalties or appeal to the tribunal if you think that you have a reasonable excuse. This applies to penalties for failure to:

• make a tax return on time
• pay a tax return on time
• keep and preserve records
• comply with, or an obstruction of, the WRA

You can also ask us to review Landfill Disposals Tax registration penalties.

What may count as a reasonable excuse

A reasonable excuse is something that stopped you meeting a tax obligation or time period, that you took reasonable care to meet. For example:

• your partner or another close relative died shortly before the tax return or payment deadline
• you had a serious or life-threatening illness
• you had an unexpected stay in hospital that prevented you from dealing with your tax affairs
• you lose records through fire, flood or theft
