>But if your company is in Estonia, you are required to charge VAT even if you earn under 60k.
Is this not simply because companies in Estonia enter VAT at 40k per year (rather than 60k)?
(and IIRC Croatia was also at 40k a year ago, now is at 60k with some politicians trying to raise the entry to 100k)
If the clients are cross border - there is no threshold, you have to charge the VAT rate of the country in which they are located from the start.
