Hi friends,
Has anything changed for you this year? A bonus, job change, business shift, investment sale, retirement withdrawal, or household change can all affect your tax picture. If you are in Santa Rosa, Sebastopol, or anywhere in Sonoma County, June is a good time to check in while there is still time to make adjustments. We recently had a client with good news. They received a substantial bonus.That is a wonderful thing. It also changed their tax picture.
Because we looked at it now, there was still time to adjust their withholding and help avoid a much bigger surprise in the spring. That is the whole point of a mid-year check-in. It gives us time to do something while there are still months left in the year.

Why a Mid-year Tax Check-in Matters
Taxes are not just something that happen in April. The IRS expects taxes to be paid throughout the year, either through withholding or estimated payments, and this is where the idea of safe harbor comes in.
Most of the time, people get into trouble because the year changed and the tax plan did not, which can affect whether you meet safe harbor and avoid penalties.
Maybe income went up. Maybe income went down. Maybe there was a bonus, a stock sale, a retirement withdrawal, or new business income. Maybe a child moved out, a spouse changed jobs, or your withholding was reduced without you realizing how much it would matter.
None of that means you did anything wrong. It just means your numbers may need a second look.
What Safe Harbor Means
Safe harbor is one of those tax terms that sounds more complicated than it is.
In plain English, safe harbor means you paid enough tax during the year to help avoid an IRS underpayment penalty, even if you still owe some tax when you file.
It does not mean you will owe nothing in April. It means you may have protected yourself from a penalty by paying enough during the year through withholding or estimated payments.
That is why a mid-year review can be so helpful. We can look at where you are, where you are likely headed, and whether your current payments still make sense.
For the IRS rules behind this, see the IRS underpayment penalty guidance.
A mid-year tax check-in is a good idea if you have had any of these changes:
A bonus, raise, or commission increase
A job change
Self-employment income or side work
Business income that went up or down
A stock sale or investment gain
A retirement withdrawal
Rental income changes
Marriage, divorce, new dependent, or household change
Reduced income
Reduced withholding
Sale of property
Starting Social Security or pension income
Some changes mean you may need to withhold more. Some may mean your estimates can be adjusted down. Either way, it is better to know now than to guess.

Quick Q&A

What is safe harbor in taxes?Safe harbor means you paid enough tax during the year to help avoid an IRS underpayment penalty, even if you still owe some tax when you file.
Can a bonus change my tax withholding?Yes. A bonus can increase taxable income and may leave you under-withheld if payroll withholding does not cover the full change.
What changes should trigger a tax projection?A bonus, raise, job change, business income shift, stock sale, retirement withdrawal, rental income change, or household change can all affect your tax picture.
Can I fix my withholding before tax season?Often, yes. A mid-year review may show whether to increase payroll withholding, adjust estimated tax payments, or plan deductions before December 31.
Should I check in if my income went down?Yes. A lower-income year can also change the plan. You may be overpaying, or your estimated payments may need to be adjusted for better cash flow.
