Buying gold bars is almost always cheaper than buying the same weight in gold coins – and the bigger each bar, the lower the cost by weight.
Depending on your local tax regime, you can reduce or completely avoid paying sales tax (VAT) by buying gold bars instead of coins, too. Your savings will also depend on the quality (or “fineness”) of the gold bars you buy.
Trading Good Delivery gold bars – guaranteed to be of 99.5% fine or above – can then cut your tax bill again in many countries, because these 100- and 400-ounce gold bars are defined as investment gold and eligible for personal retirement plans. Good Delivery gold bars reduce your costs further still by retaining main market deliverable status. Depending on your point of view the elimination of private possession and insurance arrangements is also a plus.
