On January 1st 2026, Bulgaria will officially adopt the euro (EUR) as legal tender and wave a fond farewell to the Bulgarian lev (BGN). We congratulate Bulgaria on joining the euro family with all the monetary stability and ease of use it brings.
How to handle this currency change in Toshl?
When Bulgaria adopts the euro, the best thing to do is to simply change your main currency in the Toshl settings to euro with the first (recommended) conversion option.
Your historic data will remain as it is, with historic entries remaining in the original currency you entered them in (BGN). The entires will just be given a conversion value so that the value of those past transactions will be correctly calculated in the new euro sums.
From there on, you simply add new entries in euros and that’s it. If you’re using the automatic bank connections, the banks should also send new entries in the new currency.
If you use the recommended historical exchange rates option, it will offer to also change the account currencies for manual accounts in lev to euro. We recommend you use this option if you plan on adding to the same accounts. See here for more info on how currency changes work in Toshl.

Financial accounts that update automatically (those with the green globe icon) should be automatically updated by your bank. Most could change the account currency on the same account, but some banks might also report the accounts in euros as new financial accounts.
If the euro accounts get reported as new accounts, you can keep them as they are, or merge them with the existing account if you’d prefer the continuity that provides. If you plan on merging, make sure to select to correct account pair to merge and select the option to keep updating the account from the newer one.
Several countries joined the euro area before and the conversion process on Toshl went well. We expect the same to be true this time.
For those a bit more curious, here’s how the euro area participation looks at the time of writing.
