How Fellows Should Prepare for Tax Time at the Start of the Academic Year

by 1 Comment

Most Americans don’t like to give any thought to their taxes between when their tax returns are due in mid-April and when their income forms arrive at the end of January. (Scratch that: they don’t want to think about tax anytime outside of the two weeks in early April when they scramble to assemble their returns!) The exception is when they start a new job and are asked to set up their income tax withholding by filing a W-4.

A version of this post first appeared on GradHacker.

Graduate students and postdocs – lucky us – have extra opportunities to consider tax withholding, namely every time we change funding from a compensatory source to a non-compensatory source or vice versa. Compensatory funding for your stipend comes from your job as a research, teaching, or graduate assistant. Non-compensatory funding for your stipend comes from fellowships and training grants that are technically awards, not payment for work. (If that distinction makes little sense to you, you’re not alone!) Similarly, postdoc salaries can come in compensatory and non-compensatory versions as well.

As the vocabulary that universities use for these types of funding varies somewhat, here’s how you can definitively determine which type you receive: Compensatory pay is reported at tax time on a W-2. The broadest statement that can be made about non-compensatory pay is that it isn’t reported on a W-2. Universities have different methods for reporting this pay, which include: a 1098-T in Box 5, a 1099-MISC in Box 3, a 1042-S (for international trainees), a courtesy letter, and not at all.

When it comes to tax withholding, compensatory pay is handled by universities the same way employee pay is handled by employers: The trainee files a W-4, which calculates the fraction of each paycheck that will be sent to the IRS throughout the year. Each spring, the taxpayer files a tax return that delineates her exact amount of tax due, and any excess money withheld is refunded or any additional tax due is paid. That system is relatively easy to grasp because it’s the same as what all employees in the US experience.

Fellows (by which I mean trainees whose stipends/salaries are non-compensatory) usually have a different experience with respect to tax withholding, which is the focus of this post.

A small number of universities allow fellows to set up tax withholding using a W-4, just like trainees who receive compensatory pay. If you are a fellow at one of these universities, file your W-4 and join the rest of the country in putting taxes out of your mind until next spring.

However, the large majority of universities do not handle any tax withholding on behalf of their fellows. This does not necessarily exempt those fellows from sending tax payments to the IRS throughout the year; by default, the IRS expects to receive regular payments from each taxpayer. Instead, fellows must engage with the 1040-ES and estimated tax payments, which are more typically used by the self-employed. (But: graduate students are not self-employed!) This omission of services on the part of the universities can be especially challenging for first-year graduate students on training grants or receiving fellowships, who not only may be unfamiliar with the quirks of non-compensatory pay but also the US tax system at large, especially if they have never been a full-time employee.

Fortunately, there are only a few simple steps that fellows need to take at the start of the academic year to prepare for their tax due next April:

1) Use Form 1040-ES to estimate the amount of additional tax you will pay for 2018.

Form 1040-ES is a one-page form (page 8) that assists you in making a high-level estimation of the amount of tax you will owe for this year. (If you want even more information, check out Publication 505.)

You will enter your expected adjusted gross income for 2018 in line 1. If your grad student stipend or postdoc salary is your only income, simply multiply the income on your paycheck by the number of paychecks you expect to receive in 2018. If you have a side income or were otherwise employed prior to starting your fellowship/training grant, add in that income as well.

The worksheet will then walk you through a truncated version of the calculations you will make on your tax return: subtracting your deduction (standard or itemized), calculating your tax due, and factoring in your credits and self-employment tax (from your side income, possibly).

In the end, you will have three relevant numbers: the estimated amount of tax you will owe for 2018 (line 11c), the amount you have to pay throughout 2018 to avoid being penalized (line 12c), and the amount of withholding expected in 2018 (line 13) (for instance, from your job or compensatory pay prior to your switch to non-compensatory pay).

2) Determine whether you are required to make quarterly estimated tax payments, and do so if you are.

If for 2018 you expect to have more tax withheld than the amount required to avoid a penalty, once again you can forget about taxes until next spring.

If for 2018 you will owe at least $1,000 in additional tax, you are required to make quarterly estimated tax payments. (Exception: If your withholding in 2018 is greater than the smaller of 90% of your 2018 tax due or 100% of your 2017 tax due if your 2017 tax return covered 12 months. See Figure 2-A of Publication 505.) You will send in to the IRS one-quarter of your additional tax due (line 15) by September 17, 2018 (for the period of June to August), January 15, 2019, April 15, 2019, and June 15, 2019. You can pay by mail using the vouchers in Form 1040-ES or online at www.IRS.gov/payments.

If in 2018 you will owe less than $1,000 in additional tax, you are not required to make quarterly estimated tax payment, but you will owe a lump sum at tax time.

3) Set up a system of self-withholding to prepare for your tax due quarterly or yearly.

Whether you are required to pay quarterly estimated tax or a lump sum at tax time, the best practice to handle those payments is to prepare for them with each paycheck. Basically, you should simulate your own personal tax withholding system to avoid being forced to come up with a large sum quarterly or yearly, which can be a shock to your budget or cash flow.

Divide your tax due, whether quarterly or yearly, by the number of paychecks you’ll receive in the period it covers. Transfer that amount of money each time you are paid to a dedicated savings account for tax payments. Then, when you pay your quarterly or yearly tax, draw your tax due from the “withholdings” you’ve created in that savings account. (You can also leave this money mixed in with other cash in your checking or savings accounts, but be sure to keep careful track of the amount you have earmarked for taxes so you don’t dip into it for other purposes.)

For the time that you receive non-compensatory pay, you’ll have to stay on top of making your quarterly estimated tax payments or verifying that you are not required to make them. First-year graduate students in particular should redo Form 1040-ES in January for their 2019 income, because while receiving non-compensatory pay for only the fall semester might not meet the requirement for paying quarterly estimated tax, receiving it for the entire calendar year probably will.

New Fellow? Pay Your Quarterly Estimated Tax for the First Time This Week!

Did you start receiving a fellowship this academic year as a graduate student or postdoc? First, congratulations! Second, I must clear up a pernicious misconception about fellowships in the US: you do owe federal income tax (and probably state, too) on your fellowship income. If income tax is not being withheld from your stipend/salary (and the majority of universities do not offer withholding on this type of income), you may be responsible for making quarterly estimated tax payments throughout the year. The next payment is due tomorrow, January 16, 2018! This post will guide you through how to determine whether you owe quarterly estimated tax and how to pay it if so.

Do You Receive Your Gross Income?

The IRS expects to receive income tax payments throughout the year, not just each April. Employees almost always have income tax withheld from their paychecks; instead of receiving their gross (full) income, their employer sends approximately the amount of tax the employee owes from each paycheck to the IRS and the employee receives the rest (net income).

Fellowship recipients (when the term is used conventionally; perhaps not universally) have non-compensatory pay and are not considered employees of their universities. Most universities do not offer income tax withholding on fellowship stipends/salaries. Taxpayers who do not have income tax withheld from their salaries (or who have too little withheld compared to the amount of tax they owe) are sometimes responsible for manually sending money to the IRS. This is called making quarterly estimated tax payments.

If you are a fellowship recipient (e.g., the NSF GRFP), your first step is to confirm that you are in fact not an employee, and your second step is to check whether you are receiving your gross or net income.

Step 1: The easiest way to determine if you are an employee (or rather, confirm that you are not) is to check whether you receive a W-2 for your fellowship income. (If you had an assistantship in this calendar year, you will receive a W-2 for that position, so be sure to check specifically about your fellowship income.) However, if you just started your fellowship in the 2017-2018 academic year, you aren’t due to receive (or not receive) your tax forms until the end of January 2018, and the estimated tax payment is due in mid-January. Your next best option is to inquire into what tax form you will receive for your fellowship stipend/salary. Non-compensatory pay will appear on a 1098-T, 1099-MISC, or courtesy letter or will not be reported in any way. Compensatory pay (indicating that you are an employee) will appear on a W-2. You should try asking your departmental administrative assistant, university fellowship coordinator, Bursar’s Cashier’s office, and/or payroll office. You will most likely be told that they “cannot give tax advice,” but confirming what type of tax form your income generates is not advice.

Step 2: Having confirmed that you are not an employee (if you are, you don’t need this post!), double-check the stipend/salary amount that hits your bank account. If you multiply it by the number of pay periods over which you will receive it, is it equal to the gross fellowship stipend/salary you were told you would receive or is it less? If it is less, did you at any point file a W-4 (e.g., when you had an assistantship)? You may be one of the few students/postdocs who has income tax withheld from a fellowship stipend/salary. As stated earlier, a small minority of universities do offer withholding on fellowship income, and they should use a W-4 to determine the amount of withholding.

If you are not an employee and are not having income tax withheld from your fellowship stipend/salary, you may need to make quarterly estimated tax payments.

Are You Responsible for Paying Quarterly Estimated Tax?

The IRS explains who is responsible for filing quarterly estimated tax on Form 1040-ES p. 1.

Right off the bat, you are not required to pay quarterly estimated tax if in the previous tax year your total income was zero or you did not have to file a tax return (and your return covered all 12 months). For example, if you were a student for all of 2016 and either didn’t have an income or your income was so low that you didn’t have to file a tax return, you aren’t required to make quarterly estimated tax payments.

If that first provision doesn’t apply to you, the IRS has a helpful flow chart on Publication 505 p. 24.

Publication 505 Figure 2-A

At this point, you’re going to have to do a few calculations to determine what amount of additional tax you owe for the year (additional to any withholding you already had). You simply need to fill out the worksheet on Form 1040-ES p. 8 for your household. It looks sort of involved but if you have a simple financial life you won’t actually need to put very many entries into the worksheet. You will need at your fingertips your 2016 tax return (or at least the total amount of tax you paid), your gross income for 2017, the amount of income tax you had withheld in 2017 (if any) and an educated guess as to your 2017 deductions and credits (your 2016 return will be helpful for this).

Once you calculate the amount of tax you owe in total for 2017 (Form 1040-ES line 13c), you can determine whether you are responsible for paying quarterly estimated tax.

First, look up the total amount of tax you paid in 2016. Second, take your total tax due for 2017 and multiply it by 90%. The smaller of these two numbers is the amount of tax you need to pay throughout 2017 to avoid a penalty (Form 1040-ES Line 14c).

Subtract the amount of income tax you had withheld in 2017 (Form 1040-ES Line 15) from the amount you need to pay to avoid a penalty. If the result (Form 1040-ES Line 16) is less than $1,000, you are not required to make a quarterly estimated tax payment. If the result is greater than $1,000, you are required to make a payment.

Please note that just because you are not required to make quarterly estimated tax payments does not mean you will avoid paying tax the whole year, only that the additional tax due does not have to be paid until you file your 2017 tax return this spring. Now that Form 1040-ES has given you some warning, use the next few months to prepare to make that lump sum income tax payment.

How to Pay Quarterly Estimated Tax

If you are required to make a quarterly estimated tax payment, the calculation is pretty simple since this is the last payment due for 2017! You should make a payment for all the additional tax due that you calculated you owe (Form 1040-ES Line 16a). If your calculations were exact, when you file your 2017 tax return in the spring, you won’t receive a refund or owe any additional tax. More likely, filling out your full tax return will bring to light a few adjustments in your calculations, so you may end up receiving a small refund or paying a small amount of additional tax.

The easiest way to make your quarterly estimated tax payment is online at www.IRS.gov/payments (find all your payment options on Form 1040-ES p. 3-4 or Publication 505 p. 32-33).

If you were unaware that you had any income tax liability on your fellowship income and are unprepared to pay what you owe by January 16, 2018, don’t avoid the issue! Give the IRS a call and they may be able to work with you to minimize the penalties you owe (though not the interest).

Calculating your quarterly estimated tax is not very difficult; the most challenging aspect is knowing that you’re supposed to do it! If you are a new fellow and this is your first time making a quarterly estimated tax payment, rest assured that it will be easier going forward. You first quarterly estimated tax payment for 2018 is due on April 17, 2018. You’ll want to freshly fill out the 2018 1040-ES once it’s available, but it should be similar to the form you just worked through.
