The decision is something that only you (or your accountant) can make by using your purchasing and sales figures to determine whether being vat-registered is beneficial to you.
Your buying costs will be less but your selling costs will need to be slightly higher to maintain your margin. It could mean that you become uncompetitive but it could also mean that your items become more attractive to vat-registered buyers.
I registered for vat voluntarily when I first started and do not buy from a seller who is not registered unless their price beats the vax-exclusive price of a vat-registered seller.
Given the recent VAT changes, if the referral fees are significantly impacting your margins and you’re not yet VAT registered, it might be worth considering registration. This way, you can reclaim VAT on your business expenses. However, if you’re well below the VAT threshold, it might be more cost-effective to wait and reassess when you approach the threshold. In the meantime, adjusting your pricing strategy could help mitigate the impact.
If Amazon’s VAT updates are significantly affecting your margins, it might be beneficial to register for VAT now to reclaim VAT on your business expenses. However, if you’re far from the VAT threshold, you might prefer to wait. Assess your current sales volume and projected growth to make an informed decision.
