What are estimated taxes?

Income tax is meant to be paid as income is earned. Employees have tax withheld from paychecks, but self-employed people, including most farmers, usually make payments themselves during the year. These are called estimated tax payments.

The payments cover income tax and self-employment tax. Missing them or paying too little can lead to a penalty, so understanding the system matters.

Married couples, partners and farm families should decide who tracks the payments, so one is not assuming the other has paid. Keep a shared record of dates and confirmation numbers.

How do farm rules differ?

The IRS has special provisions for farmers and fishers, because their income is often uneven. Publication 505 and Publication 225 describe these rules in general terms. Check the current versions on irs.gov for dates, thresholds and options.

No dates or percentages are given here, as they can change. Confirm them with the IRS or your CPA each year.

Farms that also have wage income from an off-farm job may be able to adjust withholding at that job instead of or alongside estimated payments. Ask your CPA about the best mix for your situation.

How do you estimate what you will owe?

Start with last year's return as a rough guide, then adjust for expected changes in income, expenses, asset purchases and government payments. A tax professional can use planning software and tell you what safe levels look like.

Update the estimate midyear. A good or bad season can change the picture quickly, and adjusting early beats facing a large bill at filing time.

Use official IRS pages or your online account to confirm what has been credited to you before filing, so mistakes do not turn into penalties.

• Last year's return and tax
• Expected income and major expenses this year
• Large asset sales or purchases
• Changes in family income or filing status

How do you set aside cash?

Open a separate savings account for taxes and move a share of each sale or payment into it. Treat it as already spent. That way a payment due date is not a surprise.

If cash is short, talk to your CPA about options before the due date. The IRS has payment plans, though penalties and interest may apply, and ignoring a bill makes things worse.

Know what each year's estimate assumes. Write down the income, expenses and tax rate you used, so you can compare with reality and learn how to forecast better.

How do you pay?

The IRS offers several ways to pay, including online, by mail and through your IRS online account. Keep records of each payment, including date and amount, and make sure they are credited to the correct year and taxpayer.

Some states also require estimated payments. Check your state revenue department.

Remember that if you have employees, payroll tax deposits are a separate obligation with their own schedule and are not part of estimated tax payments.

What mistakes should you avoid?

Ignoring estimated payments for years, assuming a refund last year means none is needed this year, mixing up due dates, forgetting self-employment tax and failing to keep proof of payments are common errors.

Plan with your CPA each year. Ask what safe harbor rules apply, how farm income timing affects you, and what to do if income jumps.

If you move, change entity or add a partner, tell your CPA early since it can change how and where payments are made.

• Missing a payment date
• Paying the wrong amount without checking
• Forgetting self-employment tax
• Not keeping proof of payment

What do you do if income changes during the year?

Farm income swings. A strong sale, a crop insurance payment, a land sale or a large expense can change what you owe. When something big happens, stop and re-estimate instead of waiting for the next scheduled payment.

Call your CPA with the new numbers. They can tell you whether to adjust the next payment, how it affects safe harbor rules and whether another option makes sense. Write down the date and result of each conversation. If income falls, you may be able to pay less, but ask before skipping a payment.

• Large sale or land transaction
• Insurance or disaster payments
• Major equipment purchase
• Loss of a lease or enterprise
