Answer 1

If you have inovice id then use \Magento\Sales\Model\Order\InvoiceRepository for getting invoice data of that invoice.

$objectManager = \Magento\Framework\App\ObjectManager::getInstance();
$invoice = $objectManager->create('\Magento\Sales\Model\Order\InvoiceRepository')->get(506585);

Answer 2

Try this, Before you order need to submit an invoice in the backend

$invoiceid=506585;
$objectManager = \Magento\Framework\App\ObjectManager::getInstance(); 
$invoice = $objectManager->create('\Magento\Sales\Model\Order\Invoice')->load($invoiceid);

/* get all data */
print_r($invoice->getData());

/*Get tax amount and subtotal */
$taxAmount=$invoice->getTaxAmount();
$subtotal=$invoice->getSubtotal();
echo $taxAmount;
echo $subtotal;

Note: Before running your script your order need to complete the invoice, Otherwise you didn't get invoice details.

Code Tested

Answer 3

Simply use below code.

$invoice_id = 506585;

$objectManager = \Magento\Framework\App\ObjectManager::getInstance();

$invoice = $objectManager->create('\Magento\Sales\Model\Order\InvoiceRepository')->get($invoice_id);

echo $invoice->getSubtotal;

print_r($invoice->getData());

Note : invoice increment id and invoice id both different things in magento.
