Mileage rates decrease

Mileage rates for business travel are set for 2021. The standard mileage rates for the use of a car (also vans, pickups or panel trucks) are:

  • 56 cents per mile driven for business use, down 1.5 cents from 2020
  • 16 cents per mile for medical, or moving purposes for qualified active duty members of the Armed Forces, down 1 cent from 2020
  • 14 cents per mile driven for charitable work. This rate remains unchanged from 2020.

Employee Retention Tax Credit

The Taxpayer Certainty and Disaster Tax Relief Act of 2020 made a number of changes to employer tax credits previously made available under the CARES Act. Among them, the Employee Retention Credit (ERC) was extended for six months and modified in a number of ways. This is for employers who kept employees on payroll despite challenges posed by COVID-19.

Social Security changes for 2021

New benefits took effect on January 1. For recipients of Social Security, these include a 1.3% cost of living increase. If you’re an individual who began collecting before full retirement age, you can now earn $18,960 before benefits are reduced.

PPP new eligible expenses

The second draw of the PPP program has expanded forgivable expenses, originally limited to payroll, rent, mortgage interest and utilities. New eligible expenses include PPE and facility modifications; unreimbursed property damage costs from 2020 looting; essential supplier expenses; and payments for certain business software or cloud computing services.
