Thank you for your question.
In the last few days we had many customers contact us with a similar question.
Yes you can use W2 Mate to e-File your W2s and 1099s with Oklahoma using the correct text format expected by OK Tap.
If you want to import your W2 data from QuickBooks then you need to have an active QB payroll subscription, this is not needed for 1099s.
Remember you can import from a spreadsheet or type your data manually, if you do not want to import from QuickBooks.
After you import / key-in your data, you can use W2 Mate to generate one text file per company for W2s and one for 1099s. We will provide you with the exact steps to do that.
You will need W2 Mate + W2 Mate Option #3 for Import + W2 Mate Option #4 for Electronic Filing.
Please refer to this question for instructions on how to e-File 1099s with Oklahoma and this question on how to e-File W2s.
