Hi,
I understand you're from the USA and that your business is located in the state of Washington.
From what I can read here (
www.avalara.com/taxrates/en/state-rates/...sales-tax-guide.html
), you apparently have to charge the sales tax based on the location of the customer ( note that I'm not from the USA, and I'm not a specialist of the USA tax system. I would recommend you check what are your obligations in that respect with a professional in that field if that's not already done ). Also, the sales tax can change based on the county, state, etc. This will be difficult to achieve without TaxCloud. Counties don't necessarily match with the post code scheme and you can only restrict sales tax based on the state, coutry and post code in HikaShop. The county is not asked and there is not mechanism to automatically deduce the county from the full address.
If you don't want to use TaxCloud and need to support sales tax dynamically calculated by county / state, that would require having a table in the database to store all the sales tax rules, and then the development of a plugin to calculate the county based on the full address by using for example Google Maps' address API, like we do with the geocoding plugin
www.hikashop.com/marketplace/product/250...shipping-plugin.html
), and based on the information you can get from the address, you can then apply the correct sales tax via an additional fee added to the cart (plugins can add extra fees to the cart, like the cart fees plugin does:
www.hikashop.com/marketplace/product/279-cart-fee.html
).
Doing this is a big endeavor. And even if you do, you then have to maintain the tax rules table when things change. Also, Google Maps' API, while cheap, isn't free. But maybe your developer has a better idea than me ?
