We report a detailed investigation of the Fermi surface in the layered Dirac semimetal TaNiTe5. We probed the magnetization, magnetic torque and magnetoresistance in high-quality single crystals. Pronounced Shubnikov - de Haas (SdH) and de Haas - van Alphen (dHvA) oscillations are observed in magnetic fields above 3T and at temperatures of up to 22K. Multiple fundamental frequencies and light effective quasiparticle masses are obtained by fast Fourier transformation (FFT) and Lifshitz-Kosevich (LK) formula fits. The high resolution of the low-temperature FFT spectra allows us to investigate individual peaks in detail for the magnetic fields applied along all three crystallographic axes and the planes in between. Our investigation can confirm the density functional theory (DFT) calculated band structure and its corresponding Fermi surface.
