Quarterly Taxes for Small Farms

What are quarterly estimated taxes in general?

When tax is not withheld from your income, as with many self-employed people and farm owners, the tax system may expect you to pay in installments through the year rather than all at once. These payments are commonly called estimated taxes, and they are usually spread over several due dates.

Rules, thresholds and due dates are set by tax authorities and can change. Check current requirements with a tax preparer or the relevant tax agency, and do not rely on dates from memory or from a general article.

Think about the other taxes that come with self-employment income as well as income tax. Your preparer can explain which ones may apply to your farm and how they affect the size of your payments.

Does my farm need to make them?

It depends on your total income, your expected tax, whether you have a job with withholding and other facts. Some farm households with other income can adjust withholding at the job instead. Some farm businesses have special rules, depending on how much of their income comes from farming.

Ask a tax preparer early in the year, ideally before your first big sale. Give them your best estimate of income and expenses, and ask what to pay, when and how. Also ask about your state, since many states have their own rules.

If you run the farm with a spouse or partner, ask how income is split and who is responsible for payments. Write down the answer so that nobody assumes someone else is handling it.

• Expected farm profit for the year
• Income from jobs, spouses and other sources
• State rules, which may differ from federal
• Due dates and payment methods

How do I estimate what I will owe?

Start with your records. Estimate sales, subtract expenses and see what profit you expect. Then ask your preparer to use that, along with your other income, to estimate your tax. Farm income is uneven, so use a range rather than a single figure.

Update the estimate as the season goes. After a big market day, a large purchase or a change in prices, a quick review can show whether your payments should change.

Mark the due dates on a calendar once you have confirmed them with your preparer, and set reminders a week ahead. Missing a date because it slipped by is an avoidable problem.

How do I plan cash for tax payments?

Set aside a share of each deposit into a separate savings account, using a percentage your preparer suggests. This turns taxes from a sudden bill into a routine expense. Farm income is seasonal, so the habit helps most in lean months.

Keep that account separate from operating money, and do not borrow from it for feed or repairs. If you are tempted, that is a sign that your budget needs adjusting. Revisit the amount after each large sale, since a good month can change what you owe. Revisit the amount after each large sale, since a good month can change what you owe.

Ask about safe harbor ideas, which are general ways to base payments on a prior year or a current estimate. Your preparer can tell you whether any apply and what they would mean in practice for your farm.

What if income is uneven or I have a bad year?

Farm income swings with weather, markets and animal health. Payments based on an early estimate may turn out too high or too low. Ask your preparer how to adjust during the year, and what happens if you underpay.

In a loss year, tell your preparer promptly and keep detailed records. Ask how losses are treated and how they may affect later years. Do not assume a rule without asking.

Keep a running note of big sales and purchases that were not in your estimate. Those notes tell your preparer when the plan needs a second look.

What records make this easier?

A monthly summary of income and expenses by category makes estimates quick and accurate. Keep records of each payment you make, including date, amount and method, and file confirmations. Note any notices you receive.

Share the summaries with your preparer on a regular schedule, perhaps each quarter. That keeps them informed and prevents surprises. Store those summaries with your bank statements so one folder holds the whole picture for the year.

Where can I get help?

Ask a tax preparer with farm experience, your extension office, your lender or local farm organizations. Many offer workshops for beginning farmers, often at low or no cost. Ask what the first visit covers and what to bring.
