Who Can DIY Their Taxes – and Who Should Use a Pro
For a lot of people, even money-savvy financial planners, it makes perfect sense to outsource this task ... and not just because it's aggravating.
There are always a handful of people that I run into this time of year who like to brag about the fact that they do their own taxes. Always have, they say — and always will.
The Cost of Financial and Tax-Related Mistakes
It’s all of those things above that can lead to less money in your pocket (not to mention a whole lot more stress and a lot less free time to enjoy things I assume you’d rather do than your own taxes). Any errors that you make on your tax return are likely to be far more expensive than any fees you’ll pay to a CPA.
The challenge with any tax-related mistake is that things tend to compound over time. Say you miss something on your tax return this year and pay less in taxes than you actually owed. If you get audited down the road, the IRS isn’t going to just shrug it off as “oh well, everyone makes mistakes.” You’re going to owe what you didn’t pay — with interest and penalties, too. According to the IRS, interest accrues on any unpaid tax from the due date until full payment is made, and late-payment penalties can add up to a maximum of 25% of the amount owed.

Making big mistakes that cost serious money or opportunities simply aren’t worth it. Not when it’s your hard-earned money on the line.
Who Needs a CPA – and Who Can Get Away with DIY
In general, most people will benefit from using a CPA. Even if your financial situation is relatively straightforward, you’ll save time and energy by getting help from a professional. You’ll also get added peace of mind that someone who lives and breathes taxes reviewed your situation. This makes mistakes less likely than if you did your taxes on your own, and also increases the likelihood that you’ll take advantage of every opportunity you can to reduce your tax bill.
All this being said, not everyone needs a CPA. Here’s a good general rule of thumb to use to help you determine if you can DIY: Do you have one source of income via a W2 from a single employer? Then you can probably get away with doing your own taxes. But the moment your financial situation gets any more complicated than that — say you earn 1099 income (even if it’s on the side of your full-time job and you don’t consider yourself “self-employed”) or you have enough deductions that you think it makes sense to itemize — it’s a good idea to find a CPA who can help you.
At the very least, you’ll save yourself time and stress, and any fee you pay to free up more time while reducing your stress is probably going to be well worth the cost.
