Magento 2 Rounding Tax Calculation Issue

Question

I use Magento 2.3.5p1 with catalog prices without tax. I have issue with tax rounding on storefront. Example calculation.

I get following result on Magento storefront for 21% vat;

45.45 * 1.21 = 54.99

But it must be €55.00 (imported order from feedmanager). I don't know where i make a mistake.

Answer 1

Magento official document can help you determining and playing around tax settings.

And this warning message section covers scenarios, when rounding warning can occur.

If you must debug, you could put a breakpoint here to check what's really going on and review the flow of calculation.
