Rounding Tax, can it be stopped?

I have the same issue, but just by .01, so I am hoping there is a way to apply tax to the total instead of each product

Hi,

I’m going to take a look, but

Could you test setting decimals to 3? (TheCartPress Settings / Localize)

Best regards

If I change the Settings > Localize, the product prices become $9.000, not the tax, but when I change it in the TCP.cartbox.class.php, the tax will show 8.250% which is correct, but the total tax calculations are still off by .01 cent.

TCP.cartbox.class.php line:
<?php if ( $see_tax_detail ) : ?> (<?php echo tcp_number_format( $tax, 3 ); ?>%)<?php endif; ?>

For example, if I add 2 units of Jasmine Dragon Pearl tea. Which makes the subtotal $20 (since each unit is $10), the tax calculated for 8.25% is .83 per unit in cart, so the total tax applied is $1.66.

BUT, if you calculate it manually $20 x 0.825 = $1.65. So the tax applied is supposed to be $1.65. Per product, customer will be charged 1 cent more.

It seems not much off, but if you buy many units of products, .01 added to each unit adds up and a penny saved is a penny earned.

You can test it in the cart.

That’s why I suggest applying tax to the total instead of each product. Normally, receipts apply tax to totals, not per unit here.

Hi Carol,

There is another line of code 225 and 26 where the rounded is applied.

225: $tax_amount_per_unit = round( $tax_amount_per_unit, $decimals );
226: $tax_amount = round( $tax_amount_per_unit * $item->getUnits(), $decimals );

The line <?php if ( $see_tax_detail ) : ?> (<?php echo tcp_number_format( $tax, 3 ); ?>%)<?php endif; ?> is only to display the tax value.

if you do not want to lose your changes you can create a plugin with your checkout step: https://thecartpress.com/docs/developer-docs/plugin-development/how-to-create-a-checkout-step-or-box/

Best regards

I changed it back to 2 since we want to entire tax rate (including two decimals) to show 8.25%.
