You cannot file a tax return using your paystub. You have to use the W-2 that is provided by your employer. Your last paystub will not have the correct information.
Employers have until January 31, 2024 to give you the 2023 W-2.
A 2023 tax return cannot be e-filed until January 4, 2024. The IRS will not be accepting any type of tax return until mid to late January, so there is no need to file until the IRS starts accepting tax returns.
