Homepage Fill Out Your Sc Estimated Form
Article Structure

The SC Estimated form, also known as SC1040ES, is an essential document for individuals in South Carolina who anticipate owing a substantial amount of income tax. This form serves as a declaration for estimated tax payments, which are required if one expects to have a tax liability of $100 or more with their SC1040 return. The form outlines specific instructions that include payment options, filing deadlines, and eligibility criteria for certain individuals, such as farmers and commercial fishermen, who may have alternative payment arrangements. Furthermore, the form requires individuals to enter their Social Security Numbers, indicate the quarter for which they are making the payment, and specify their payment amounts precisely. For those opting to pay electronically, the South Carolina Department of Revenue has provided a user-friendly online tax portal, MyDORWAY. If payment is made via check, certain guidelines must be observed, such as making the check payable to SCDOR and including relevant identification details in the memo line. Overall, understanding the SC Estimated form is crucial for compliance and avoiding penalties associated with insufficient or late payments.

30801211

Filing requirements

You must file a declaration of Estimated Tax if you expect to owe an Income Tax liability of $100 or more with the filing of your SC1040, Individual Income Tax Return.

Use the Estimated Tax Worksheet to compute your Estimated Tax:

If you are a resident of South Carolina, use your 2020 SC1040 as a basis for figuring your Estimated Tax.

If you are a nonresident of South Carolina, use your 2020 SC1040 and Schedule NR as a basis to calculate the modified South Carolina taxable income to enter on line 3 of the Worksheet.

Exceptions to filing a declaration of Estimated Tax:

Farmers and commercial fishermen whose gross income from farming or fishing for 2020 or 2021 is at least two-thirds (66.67%) of their total gross income from all sources. Instead of making four quarterly Estimated Tax payments, farmers and commercial fishermen may choose to pay all of their Estimated Tax by January 18, 2022 or file their 2021 SC1040 and pay the total tax due by March 1, 2022

Individuals whose prior year tax liability was $0 for a full 12 months

Nonresidents of South Carolina doing business in this state on a contract basis where the contract is more than $10,000 and tax is withheld at 2% from each contract payment

Declaration adjustment

If your Estimated Tax is substantially increased due to a change in income, dependents, or Income Tax withholding, file the adjusted declaration by the next payment due date. Use the SC1040ES to make the adjusted payment.

Complete the Adjusted Declaration Schedule, found in these instructions, to determine the amount to be paid. Use the corrected amounts of income and deductions from your federal information.

Payment due dates

1.If you file using a calendar year end of December 31, your Estimated Tax payments are due in four equal installments:

1st quarter due April 15, 2021

2nd quarter due June 15, 2021

3rd quarter due September 15, 2021

4th quarter due January 18, 2022

You can choose to pay all of your Estimated Tax on April 15, the due date of the first installment. Instead of making your last payment on January 18, you can choose to file your SC1040 by February 1 and pay the full balance of Income Tax due.

2.If you are not required to file on April 15 and:

you meet your Estimated Tax filing requirement after April 1 and before June 1, your first Estimated Tax payment is due on June 15, 2021.

you meet your Estimated Tax filing requirement after June 1 and before September 1, your first Estimated Tax payment is due on September 15, 2021.

you meet your Estimated Tax filing requirement after September 1, your first Estimated Tax payment is due on January 18, 2022.

3.If you file on a fiscal tax year, your Estimated Tax payments are due on the 15th day of the fourth, sixth, and ninth months of the fiscal year and the first month of the following fiscal year.

Penalty for failure to file and pay Estimated Tax

You may be charged a penalty if:

you do not pay enough Estimated Tax.

you do not make your payments by the due date and for the required amount.

you do not pay at least 90% of the total tax due.

A penalty will not be charged if your underpayment results from personal service income earned in another state and tax was withheld to the other state.

Generally you can avoid a penalty if you make timely Estimated Tax payments equal to 100% of the tax shown due on your SC1040 for the prior tax year. You must have filed a SC1040 for the prior tax year and it must have covered a 12-month year.

If the adjusted gross income on your prior year SC1040 was more than $150,000, the 100% rule is adjusted to 110% of last year's tax liability. Calculate adjusted gross income by using federal guidelines and making South Carolina adjustments.

Refer to the SC2210 at dor.sc.gov/forms for more information on computing the underpayment penalty.

Social Security Privacy Act Disclosure

It is mandatory that you provide your Social Security Number on this tax form if you are an individual taxpayer. 42 U.S.C. 405(c)(2)(C)(i) permits a state to use an individual's Social Security Number as means of identification in administration of any tax. SC Regulation 117-201 mandates that any person required to make a return to the SCDOR must provide identifying numbers, as prescribed, for securing proper identification. Your Social Security Number is used for identification purposes.

The Family Privacy Protection Act

Under the Family Privacy Protection Act, the collection of personal information from citizens by the SCDOR is limited to the information necessary for the SCDOR to fulfill its statutory duties. In most instances, once this information is collected by the SCDOR, it is protected by law from public disclosure. In those situations where public disclosure is not prohibited, the Family Privacy Protection Act prevents such information from being used by third parties for commercial solicitation purposes.

What You Should Know About This Form

What is the SC Estimated Tax form (SC1040ES) and when do I need to file it?

The SC Estimated Tax form, known as SC1040ES, is a declaration that you must file if you anticipate owing $100 or more in state income tax for the year. This could apply to various situations, such as self-employment or income not subject to withholding. Generally, you should use the form if you expect to file your South Carolina Individual Income Tax Return (SC1040) and owe a tax liability. Filing is typically required by April 15, but the exact due date may depend on your unique tax situation or any changes in your income.

How do I make payments using the SC1040ES form?

You have a few options for making payments on your SC1040ES. The most convenient method is to pay online using MyDORWAY, the tax portal managed by the South Carolina Department of Revenue. Just visit dor.sc.gov/pay to get started. If you prefer to pay by mail, ensure that you do not send cash. Make your check payable to SCDOR, and include your name, Social Security Number (SSN), and "2021 SC1040ES" in the memo line. Remember to mail your SC1040ES along with your payment together in one envelope, preferably stapling them for safety.

What are the penalties for not filing or not paying my Estimated Tax?

If you fail to file the SC1040ES or do not pay the required amount by the due date, you may face penalties. Specifically, a penalty might be charged if you do not pay at least 90% of the total tax owed or if you do not meet the necessary payment deadlines. However, if any underpayment results from income earned in another state where taxes were withheld, penalties may be avoided. For the best protection against penalties, making timely payments equivalent to the previous year’s tax liability can help.

Can I adjust my Estimated Tax declaration if my income changes?

Yes, you may adjust your Estimated Tax declaration if there is a significant change in your income, dependents, or withholding amounts. If an adjustment is needed, file a new declaration with the SC1040ES form by the next payment due date. You will also need to complete the Adjusted Declaration Schedule as part of the process. This will help determine the correct payment amount based on your updated financial situation.

Common mistakes

Filling out the SC Estimated Tax Form (SC1040ES) can be straightforward, but many make common mistakes. One frequent error involves incorrect Social Security Numbers (SSN). Always ensure that both your SSN and your spouse’s (if applicable) are entered accurately. A simple typo can delay processing and cause penalties.

Another mistake is failing to mark the correct payment quarter. Each quarter has a designated box that must be marked; omitting this step may lead to confusion in payment allocation. Additionally, not entering your name and address, including an apartment number if necessary, is another common oversight. Missing this information can result in complications in tracking your form and payment.

Many individuals also miscalculate their payment amount. It’s essential to follow the guidelines provided in the instructions carefully. Enter the payment in whole dollars, excluding the dollar sign, and ensure it matches the amount on line 11 of your Estimated Tax Worksheet. Discrepancies here can lead to delayed processing or penalties.

Another frequent error involves mailing paper forms with payments when paying electronically. If you opt for online payment through the MyDORWAY portal, do not send a paper copy of the SC1040ES. This could create unnecessary confusion in the payment system and lead to duplicate entries.

Improperly completed checks also pose a problem. Remember to write your name, SSN, and 2021 SC1040ES number in the memo line of the check. Failing to do so may delay the payment's application. Additionally, do not send cash, as cash payments are not accepted.

Lastly, some taxpayers neglect to mail their SC1040ES and payment together in one envelope. It is also important to staple the payment to the SC1040ES. This small step can prevent the documents from being separated during processing, which could result in complications with your payment history.

Documents used along the form

When managing your tax obligations in South Carolina, the SC Estimated form plays a vital role. However, it's not the only document you may need to familiarize yourself with. Below is a list of seven other essential forms and documents that are often used in conjunction with the SC1040ES, each serving a distinct purpose in your tax filing process.

  • SC1040: This is the South Carolina Individual Income Tax Return. It is used to report and pay the final income tax due after all estimated payments have been accounted for. You'll complete it after the tax year ends to reconcile your income and tax liability.
  • SC Tax Worksheet: Before submitting your SC1040ES, you'll want to prepare using this worksheet. It helps you calculate your estimated tax liability based on your expected income, deductions, and credits, ensuring your payments are accurate throughout the year.
  • SC2210: This form is for calculating any penalties for underpayment of estimated tax. If you find that you owe a penalty because you didn't pay enough estimated tax throughout the year, you'll use this document to determine the amount owed.
  • SC4972: This form is used to report any additional taxes that may apply, such as for specific tax credits or liabilities that affect your overall tax obligation. It helps ensure that any unique circumstances are taken into account when filing your tax return.
  • W-2 Form: This crucial document is provided by employers and outlines your annual earnings and the taxes withheld from your paycheck. You’ll need this to accurately report your income and claim credits on your SC1040.
  • 1099 Forms: If you have income from freelance work, interest, or dividends, you will receive various 1099 forms. These forms detail income earned outside of traditional employment, and you'll report this income on your tax return.
  • Payment Voucher: If you owe taxes when filing your SC1040, you may need to submit a payment voucher along with your payment. This voucher confirms your payment details and helps the state process your payment correctly.

Staying organized and aware of all relevant forms will aid in the smooth completion of your tax filings. Each document plays its part in ensuring that your estimated tax payments are accurate and reflective of your actual tax position. Familiarity with these forms can simplify the often daunting task of tax season.

  • SC Form CR:** This is the South Carolina Tax Credit form. While the SC Estimated form addresses estimated payments, this form aids in claiming various credits that can reduce overall tax liabilities.

Misconceptions

  • Misconception 1: You only need to file the SC Estimated form if you owe a large amount of tax.
  • Many people believe they only need to file the estimated tax form if they owe $1,000 or more. However, if you expect to owe $100 or more with your SC1040 filing, you must file the SC1040ES.

  • Misconception 2: Electronic payments are not allowed for the SC Estimated Tax.
  • Some taxpayers think they must mail a paper form and check. In reality, the South Carolina Department of Revenue encourages using their free online tax portal, MyDORWAY, for payments.

  • Misconception 3: You cannot adjust your estimated tax payments once submitted.
  • Some taxpayers might think their initial submission is final. This is not the case. If your income or tax situation changes, you can file an adjusted declaration by the next payment due date.

  • Misconception 4: You can pay any amount on the SC Estimated form.
  • It is crucial to make sure your payment amount matches the calculations on your Estimated Tax Worksheet. If you neglect to align these figures, you may face penalties.

  • Misconception 5: You don’t need to report anything if your payment amount is $0.
  • Some individuals think a $0 payment means they can ignore the form entirely. However, if no payment is due, you must still submit the SC1040ES to indicate that.

  • Misconception 6: You can send cash for your payments.
  • Sending cash is a common misconception. For your safety and the Department of Revenue's procedures, always make your check payable to SCDOR and avoid sending cash.

  • Misconception 7: All taxpayers can skip the estimated tax payment if they filed last year.
  • This is not accurate. Even if you filed last year, you still need to assess your current year's tax liability to determine if estimated payments are necessary.

1. Use the SC1040ES form to declare your estimated tax if you expect to owe at least $100 with your SC1040 return.
