It can be pretty complicated. What you may need to do is go to the SPDR GLD Tax Reporting page at
https://www.spdrgoldshares.com/media/GLD/file/SPDR-Gold-Trust-Tax-Information-2023.pdf
There are also online calculators available that you can use - but I suggest still downloading the above document to get a feel for what is going on.
The sales amount each month will be based on your holdings. The basis calculation stretches back to when you first bought your shares, as these sales have happened monthly ever since, and each one affects your basis. After that, then your capital gain or loss from that sales (to cover GLD's expenses) are simply calculated by sales amount less the basis amount.
I have a spreadsheet I set up the first year I had GLD, because even TD didn't track the basis. If you haven't tracked your basis, then you might want to use one of the online calculators - I cannot vouch for them but at least one I tried matched my spreadsheet. One such website can be found at https://costbasistools.com/gold/gld.php . I also saw at least one downloadable spreadsheet to calculate it when I searched today, but have not looked at it or downloaded it.
