Thank you for calling it the refund and not the return. Too many use the terms interchangeably and it drives me nuts.
I filed the first week of Feb and got my Federal refund almost 3 weeks later. My State return got sent for a manual review and I had to wait for paperwork in the mail to prove my identity. They said it could be 12 more weeks before I see my refund. So State taxes will be about mid-June when I finally get that refund. /mad
Here any tax rebate is deducted automatically from the assessment. Most companies auto-file for their employees via IR81 and most employees get a text from IRAS saying there is no need to file, unless you have other income in Singapore. I don't so I am done for FY2020. Just waiting for the bill!
I still don't have all my tax forms yet. Every year for the past few years I get one K-1 that usually comes the last week in March and at least one 1099 Revised Form.
