The next version of the F 941-X (to allow for corrections to the new lines added to the 2Q Form 941) is expected in late September. In the meantime: If adjusting 1Q 2020 or earlier, you may use the existing Form 941-X. If adjusting 2Q (or later) and not making any increase or decrease to the employer share of social security tax or any of the new COVID-related lines that were added to the Q2 Form 941, we strongly recommend that you not use the existing Form 941-X but rather wait for the new Form 941-X revision to be released. If adjusting 2Q (or later) and making any increase or decrease to the employer share of social security tax or any of the new COVID-related lines, do not use the existing Form 941-X; instead, wait for the new Form 941-X revision. Please do not send a Form 941 with “Amended” (or similar notation) written on it in an attempt to adjust any quarter. If you have already done either of 3-4, you’ll need to wait for correspondence from IRS to find out if your return was processable or had to be rejected. Given the backlog of paper forms and correspondence due to COVID-19, we are unable to approximate how long that may be.
