Try creating an observer sales_quote_add_item

<events>
    <sales_quote_add_item>
        <observers>
            <priceupdate_observer>
                <type>singleton</type>
                <class>mymodule/observer</class>
                <method>updatePrice</method>
            </priceupdate_observer>
        </observers>
    </sales_quote_add_item>
</events>

Then reset the values that charges tax

public function updatePrice($observer) {
    $event = $observer->getEvent();
    $quote_item = $event->getQuoteItem();

    $quote_item->setTaxPercent(0);
    $quote_item->setTaxAmount(0);
    $quote_item->setBaseTaxAmount(0);

    $quote_item->setPriceInclTax($quote_item->getPrice());
    $quote_item->setBasePriceInclTax($quote_item->getBasePrice());
    $quote_item->setBaseRowTotalInclTax($quote_item->setBaseRowTotal());

    $quote_item->save();
}
