We complied the most important dates to keep in mind when you are doing business in the US. We advise you to put them in your calendar so you don't miss anything.
January 1st, 2019
Start of the 2019 tax year. The fiscal year in the US is the same as the calendar year.
January 17th, 2019
If tax is automatically deducted by your employer, you probably don’t need to worry about this deadline.
However, if you didn't pay your income tax for the year 2018 through withholding (or didn't pay in enough tax that way), you must use Form 1040ES.
For example, if you’re self-employed or a landlord, you need to pay your final instalment for the year 2018. You don't have to make this payment if you file your 2018 return (Form 1040).
January 31st, 2019
If your business works with any contractors, be sure to get their 1099 forms in the mail by the end of January. They must be postmarked or electronically filed by this date.
February 15th, 2019
Deadline for Individuals
If you claimed an exemption from income tax withholding last year on Form W4, Employee's Withholding Allowance Certificate, you must file a new Form W4 by this date to continue your exemption for another year.
Deadline for businesses
To give annual statements to recipients of specific payments made in 2018. Business can use the appropriate version of Form 1099. Form 1099 can be issued electronically with the consent of the recipient.
February 28th, 2019
Deadline for businesses to submit forms 1099 and 1096, if filing on paper. These documents relate to business transactions that aren’t covered by W2 (anything that falls outside of tips and wages – hiring an independent contractor, etc.). If filing electronically, the deadline is March 31st.
March 15th, 2019
Deadline for corporate tax returns. Corporations who use the calendar year as their tax year (i.e. their deadlines don’t straddle 2018 and 2019) are eligible for a 6-month extension but must apply for it by this date.
March 31st, 2019
Deadline for electronic Filing of Forms 1097, 1098, 1099, 3921, 3922, and W-2GS. This date applies only if you file these forms electronically.
