After you file

Yes you should pay estimated taxes.  Penalties may be assessed and interest is accrued daily.

 

Yes you can make estimated tax payment online.

 

If you make $20K you would be in the 10% tax bracket.  If single you would get a $12,400 standard deduction. 

 

Yielding a tax of $960.

 

However, if you are self employed you will have to pay self-employment tax (Social Security & Medicare).  This is an additional 15.3% on the entire $20K.

 

That would be an additional tax of $3,060.

 

Coming to a total tax of $4,020

 

 

The underpayment penalty may apply if :

  • The amount of tax you paid during the tax year is less than 90% of the tax that you owed for the current year. 
    • Example:  in 2020 you had $8,500 withheld in taxes.  Your 2020 tax return shows that you owe $10,000.  That is less than 90% and there will be a penalty.
  • The amount you paid during the tax year didn’t at least equal 100% of your taxes owed the prior year. 
    • Example:  Your 2019 tax return showed that you had $9,000 as a total tax obligation.  You paid $9,001 in withholdings in 2020.  Your 2020 tax bill comes in at $20,000.  There is no penalty because you paid 100% of the 2019 tax.
  • The IRS also says you can probably avoid the penalty if the amount you owe is less than $1,000, after subtracting withholdings and refundable credits.
