Thanks for reading, and I look forward to working with you!

Hello! I recently made a website called DopaHaul (dopahaul.com), inspired by the dopamine shopping trend that became popular in Korea. The idea is simple: you can browse products, add to cart, place orders, and track deliveries without spending any real money. All products, reviews, promos, and deliveries are fully simulated.

The idea is to help people who have online shopping habits or tendencies satisfy yung psychological urge of browsing and shopping online, without actually spending real money. I made it as a way to replicate that “shopping experience” without ending up with unnecessary purchases or expenses.

No real money involved, no data collected. All data is stored locally in your browser (localStorage).

Would really appreciate any feedback or suggestions on what I could improve or add.

Hello! Gumawa ako recently ng website called DopaHaul, inspired sa dopamine shopping trend na sumikat sa Korea. Simple lang yung idea niya: pwede kang mag-browse ng products, mag-add to cart, mag-place ng orders, at mag-track ng delivery kahit wala kang ginagastos na totoong pera. Lahat ng products, reviews, promos, at deliveries ay simulated lang.

If nagfile po ba ng first quarter LATE sa 1701q, automatic po ba na mavovoid yung intention to avail 8% kahit naclick po yung 8% sa forms na sinubmit?

For example po registered ng 2023, tapos late filling for ng first quarter sa 2025, does that mean na hindi na po sya qualified for availing and 8% and will automatically have 3% percentage tax?

Hello po mag aamend po ako ng 2025 Q1-Q3 ko dahil may undeclared sales ako for these quarters. Paano po process nito? Tama po ba ito?

1. File an amended return in ebir forms

2. Go to rdo for computation of charges and penalties

3. Pay the computed charges and penalties.

Additional question:

-Do i need to wait for email confirmation receipt po ba for my ammended return before going to rdo?

-Saan po ito babayaran pwede ba thru myeg and what to fill sa required filled nito?

-What happens after i paid all the charges and penalties? How can i make sure na naprocess po ito?

Sana po matulungan nyo ako.. TIA!

Hi! Does a total of 73k undeclared sales will trigger an audit or discrepancy notice to BIR? For context, i unknowingly undeclared a total of 73k for my q1-q3 of 2025. Pero sa annual ITR ko, idinagdag ko na duon yung kulang na 73k from q1-q3. Ayos lang kaya na ibinawi ko sa annual ITR ko yung kulang from q1-q3? I am a non vat 8% online seller.

Hello! For context, i am a shopee seller and registered my business last May 2024 (sole prop, non vat, 8%). Please don't judge me, i know pagkakamali ko ito and im willing to correct it now.

Starting year 2024 to 2025, kulang pala yung nafifile kong gross sales sa 1701q at 1701a ko. Starting may 2024, ang naideclare ko lang na annual gross sales ko ay 84k instead of 102k. So may undeclared sales ako na around 18k sa 1701q at 1701a ko for 2024. Hindi naman ito intended, nangyari ito dahil ang naidedeclare ko pala ay yung net sales ko which is yung total payout released sa shopee and not yung merchandise subtotal (na yun pala dapat). Ngayong 2026 ko lang narealize yung pagkakamali ko.

For year 2025 naman, mali rin yung naideclare ko for 3 quarters. Yung net sales lang ulit ang naifile ko instead of gross sales. As for annual itr, since naging may 15 ang deadline, nito ko na rin nalaman na mali yung finifile kong amount, ang ginawa ko is ifinile ko na yung tamang gross sales ko sa 1701a. 540k yung gross ko and binayaran ko na rin yung tax due.

My question is, tama lang ba yung ginawa ko na ihinabol ko sa annual itr ko yung undeclared sales ko from q1 to q3 of 2025? (Sorry ngayon ko lang naisip harapin at itanong ngayong nagawa ko na. Pinapapak na kasi ako ng konsensya ko gabi gabi kakaisip dito).

Another question is, what is the best thing to do para maitama ko yung 2024 and 2025? Hayaan ko na lang ba yung 2024 since under 250k lang naman sya and not taxable pa rin? Or need ko iammend and ideclare na yung tamang amount? As for ammending, pwede ba to iammend considering na nung may 2024 pa ito? And if meron ba itong penalty if ever na mag ammend?

Huhuhu badly need your answers for this. Gusto ko nang ayusin.
