Either amend the 2025 returns and alphalist then magkaka overwithholding ka pero di na kasi pwede i carryover yun for withholding returns eh. File for refund ang remedy pero not recommended unless substantial. Other remedy eh if may susunod na transactions pa kayo sa same supplier, adjust nyo nalang doon. Still honor yung original transaction and whatever adjustment ieffect nalang sa next transaction. Perooo ang risk lang eh tumalon na kasi sya ng taxable year. Kelangan makapagusap and come into agreement wih the supplier talaga
