The answer is YES. Even if you don’t reach the specified annual threshold you can choose to register for VAT.
There are many benefits of electing to register for VAT. One of the biggest is reclaiming VAT on your purchases. Practically it means that the Revenue Office will give you back the VAT portion of expenses which relate to your business, like rent, utilities, vehicle fuel, office supplies, equipment, etc.
This is very important for every business, especially in the early stages of existence. Getting this money back may have a big impact on the cash flow. If you have started a new business but have no sales yet, you may choose to register for VAT and get back the VAT paid on start-up expenses.
