What is the maximum number of W2G's that can be e-filed in a single year's tax return before a paper return must be filed instead?

[Leonard · Accepted solution]

If you have multiple W-2G's from the same casino you can add the amounts from the individual W-2G's into one total and report the total as if were from one W-2G.  This will make entering multiple W-2G's from the same casino an easier process.  The IRS does not count the number of W-2G's you receive from a casino only the total amount they paid you.  However, do not mix W-2G's from different casinos together.
