magento2 – Magento 2.3.3 Tax question

I know this is a common issue, but cant seem to find a proper answer anywhere.
I am running a Magento 2.3.3 shop and have my product imported through a plugin and these are imported excluding tax (i cannot change this, my industry suppliers work on excluding tax and this is how the prices are imported).
No matter what tax settings i use the inc VAT prices are always wrong when added to the cart.
For example, i have a product that sells for £8 inc VAT, so the ex VAT price set in the catalog is £6.67. The catalog and product pages display this correct at £8, but when a quantity of 2 is added to that cart it shows at £8.01 each.
I had an order yesterday for:
2 x £8
2 x 17 (these show as £17.01 in the cart)
£5 delivery

Magento works this out at £55.02, not £55. Before tax it displays as £45.85, not £45.83 like it should be.

No customers have yet questioned it, but it is frustrating and only a matter of time until somebody does.

My current tax settings are:
Tax Calculation Method Based On: Total (Have tried unit and row and i would prefer unit)
Catalog Prices: Excluding Tax (has to be this way)
Shipping Prices: Excluding Tax

Discounts are a whole other ball game and dont seem to be ale to do calculate discount after and including tax but this is not my worry for now.

I would like to figure out how i can display, in this example the prices correct with a total of £55 inc VAT. I know this is a rounding issue but dont know how to solve it. All prices are imported at 2 decimal places.

Thanks

magento2 – Magento Catalog price including tax is showing wrong calculation

Magento catalog price showing price excluding tax but all the settings are inclusive of tax.

My product price is Inclusive of Taxes; Say 1000

In Calculation Settings -> Catalog Price = Including Tax

In Price Display Settings -> Display Product Prices In Catalog = Inclusive Tax

But the price in catalog shows deducting tax amount from the price mentioned in Product from admin panel.

Very strange, if I choose to show inclusive and exclusive both. I get both prices as same on frontend.

Also, if I choose, In Calculation Settings -> Catalog Price = Exclusive.

Frontend shows price as correct as 1000 but within few hours if I visit the page again. It shows 1000 – taxes.

I these steps when I try, I am cleaning the cache properly, even generating static files again.

But product price on the front end still 99.00

usa – UK US tax treaty J1 visa Article 20: Do researchers count as “professors or teachers”?

I’m in the US doing research, and from the UK. I’d like to claim the UK-US tax exemption. I think that I am eligble, as my role is completely research based. However my HR department isn’t sure as I’m not technically a “professor” or “teacher” (the language stated in the tax treaty, although neither term is defined in the document). Other people I know at different institutions seem to be sure that I qualify. Can anyone provide a reference for me to show to my HR department to convince them.

Thanks,
Michael

tax query – tax_query will produce nothing

I want to display custom type posts from a custom taxonomy category so I did this:

$news = get_posts(
array(
    'posts_per_page' => -1,
    'post_type' => 'news',
    'tax_query' => array(
            'taxonomy' => 'news_category',
            'field' => 'term_id',
            'terms' => 82,
        ),
    )
); 
$postslist = get_posts( $news );    

foreach ($postslist as $crap) { ?>
     <a href="<?php $crap->title; ?>"><?php $crap->title; ?></a>
<?php }?>

I get nothing from this. Why is that? I double checked the category ID and its correct. Also, I used the Custom post types plugin to register the custom taxonomy.
