Forms 1099-NEC, W-2, and W-3 are due Tuesday, January 31, 2023.  Forms 1099-MISC are due Tuesday, February 28, 2023 (paper-filed) or Friday, March 31, 2023 (e-filed).

Getting ready for tax filing season

“EXTENDED” FILING DEADLINE:  With the weekend and federal holiday, the filing deadline for individual income tax returns this year is pushed back to April 18th.  As always, the earlier you get your documents to us the better, so please send us your W-2s, 1099s, K-1s, etc. no later than February 15th.  Most should be delivered to you in late January or early February.

TAXCADDY:  We will continue to use TaxCaddy as our document delivery system.  For clients that are new to the Dental Accounting Group, you will receive a separate email with instructions on how to setup your account.  It is a secure portal that allows us to request specific documents, and you can even upload them by taking pictures with your phone.  Once your return is complete, it is also the place where you will receive your digital copy of the return.  If you have not received your invitation by early February, please let us know.

ID THEFT PIN: If you have been the victim of identity theft in recent years, the IRS will likely mail you a PIN number which must be included with your filed tax return.  Do not forget to include that letter with your tax documents.


With recent inflation, several IRS amounts received significant increases for 2023.




401(k) deferral max



401(k) catch-up if 50+



SIMPLE deferral max



SIMPLE catch-up if 50+



FICA wage base



Business mileage rate

62.5 cents/mile

65.5 cents/mile

Standard deduction (single)



Standard deduction (married joint)



While the individual tax rates remain the same ranging from 10% to 37%, the brackets within which each rate begins have been adjusted upward as well.


Form 1099-K has been around for several years and is used by payment processing companies (credit cards, PayPal, Venmo, etc.) to report certain transactions.  In prior years, they were only required if a recipient received more than $20,000 and 200 transactions in a year. That was set to change to $600 and no transaction minimum for tax year 2022. This would result in millions more 1099-Ks being issued to individuals who had never received one before.

After many complaints, the IRS acquiesced at the last minute to delaying the change for another year, so the lower threshold will go into effect this tax year, with the first such 1099-Ks issued in January 2024.

It is important to note that the actual taxation of such transactions has not changed. If you receive payment for services through Venmo or sell something on eBay, you are required to report the income (if the sale results in a gain; a loss is likely a non-deductible personal loss and is not reported). The only change surrounds who is issued a 1099-K.

The backlash related to scenarios such as splitting the bill at a restaurant and reimbursing a friend through PayPal. That remains a non-taxable event. But the payment processing company likely does not know what the payment was for and will issue a 1099-K if your annual total exceeds $600. While still a little unclear, the likely result in that scenario is to show the “income” on your individual income tax return, then back it out as non-taxable. Failing to report the income at all could result in a notice from the IRS that you underreported income.


As a reminder, Washington State enacted a 7% tax on capital gains for Washington residents with gains above $250,000 (with exceptions for assets such as real estate, property used in a trade or business, etc.).  It went into effect January 1, 2022, which, as things stand, means taxes on 2022 gains will be due by April 18, 2023.  According to the WA DOR, if the Court eventually finds the statute to be unconstitutional, any tax payments received will be promptly refunded with interest. 

We have explored this topic multiple times, but we still do not have a final decision on if it will stand.  A recent court case reversed a prior decision that barred the State from collecting the tax.  While it technically allows the State to collect the tax, it essentially just ensures that the State Supreme Court will have to ultimately decide on the tax’s legality.

Max Deferral

IF 50+










The 2022 maximum total contributions to a defined contribution plan (401k/Profit Sharing, SEP) is $61,000 or $67,500 with an over 50 catch-up contribution.  


We encourage our clients to review their retirement plan every few years to be sure they are utilizing the most advantageous plan available. 


Reporting of Self-Employed Health Insurance Premiums for S Corporation Shareholders: the total premiums paid must be reported as wages on Form W-2.  We will be in touch early December to be sure you have reported for 2022.

2023 Salary Schedules for S Corporations or Family Members on Payroll: For those whom we provide recommended salary and withholding levels, updated schedules will be sent to you in mid-December.  Be sure to watch for this important document and have it established with your payroll company for the first payroll run in 2023.  (We do not automatically enter this data to your payroll provider so you or your bookkeeper will need to do so).

Depreciation Schedule Clean-Up: Near the end of the year, we will be sending you a copy of your most recent depreciation schedule, which lists all the assets currently in use by your practice.  Reviewing this and letting us know of any assets that are no longer in service – whether sold, scrapped, broken, obsolete, etc. – is key to making sure we capture all depreciation deductions.  If we prepare your annual Personal Property Affidavit, this is also the same schedule that the county uses to assess your personal property taxes.

Deferred payroll taxes

For those who took advantage of the pandemic assistance that allowed some employers to defer 2020 payroll taxes, the time is almost here to pay in all such taxes.  The temporary relief allowed for 50% of the deferred amount to be paid back by December 31, 2021, and the remainder is due on December 31, 2022.  Most payroll companies do not automatically process these payments, so it is up to the employer to make sure these are paid back in full by the final deadline.

HHS Reporting – Round 3

Yet another reminder of the reporting requirements for those who received funds from the HHS Provider Relief Fund.  Round 3 of the reporting is for those who received funds between January 1, 2021, and June 30, 2021.  Most dentists received funds under the program in an earlier period, so this will only apply to a small number of our clients.

Reporting for this window was due by September 30, 2022.  However, if you missed the deadline, there is a process for late reporting, which can be done at: https://www.hrsa.gov/provider-relief/reporting-auditing/late-reporting-requests

The next reporting phase opens on January 1, 2023, but again it would be very rare for any dentists to fall under this window.


Year-end tax planning is a crucial step in managing your tax bill for 2022 and establishing your safe harbor required tax payments or withholding for 2023.  Many dentists are aware that fixed asset purchases along with accelerated depreciation is a useful tool to reduce your taxable income.  This year it is especially important, as bonus depreciation will no longer be 100% of the asset starting January 1, 2023.  It will reduce to 80% in 2023, 60% in 2024, and continue to reduce another 20% each year.

However, you should also be aware of the “placed in service rule” that applies to dental equipment and other “fixed assets”.  In general, fixed assets are those items expected to last longer than a year in the practice – such as dental equipment, office furniture and fixtures, etc. and cost more than $500 per unit.  To be considered “placed in service” the item must be delivered and placed into a state of readiness.  It is not required the item actually be used; rather, just usable.

Consider Equipment Order Lead Times:  With less than three months left in 2022, if you plan to place equipment in service and deduct its cost this year, you will want to consider ordering as soon as possible.  Documenting placement in service can be done with an installation receipt or photograph that includes the date (computer, cell phone, etc.)

Of course, we would urge caution against buying assets solely for a tax deduction.  Such purchases should only be for items that you know you will need or have been thinking about buying.  Particularly for S Corporation owners, you should also be mindful of your “tax basis” in your practice, which could potentially limit the amount of deductions you can take in a given year.  Your basis increases with taxable income and money put into the company.  It decreases with losses or deductions as well as distributions taken out of the company.  Your basis cannot fall below zero, so if you have losses or large distributions, this could result in some unintended tax consequences.  Ask your account manager if you are unsure of your basis amount.
