The Most Common Tax Planning Mistake We See at LMN Tax Inc.
"At LMN Tax Inc, we frequently see self-employed clients surprised by a large April tax bill. Not because they didn't earn well, but because they treated taxes like an afterthought. The most common pattern: a 1099 contractor earning $80,000 who saved nothing for quarterly payments, then owes roughly $17,000 plus an underpayment penalty on top. The fix is straightforward: set aside approximately 25–30% of each payment you receive and make quarterly payments by the due dates. Use the calculator above to get your specific number. For a personalized review, contact our team or call (571) 326-7900."
