State‑Specific Municipal Portfolios: When Do the Benefits Outweigh the Costs?

Recent tax reform has increased the dialogue around state preference municipal portfolios, and some municipal investors are inquiring whether state-specific or state preference portfolios are a good fit in the current environment. We have found that although state-specific municipal bond separately managed accounts may offer tax benefits at the state and local level, investors often are better off allocating at least a portion of their portfolios to out-of-state (national) securities to improve diversification, credit quality and after-tax yields. The question is which solution or blend is best for a given investor, and a number of factors inform whether a state-specific portfolio may make sense.

Weighing state-specific municipal bond separately managed account solutions

PIMCO offers many state-specific and state preference municipal bond separately managed account strategies, including muni bond ladders, and can customize investor portfolios across a number of parameters. When determining the appropriate allocation to in-state versus national bonds, we consider several key factors:

  • The investor’s effective tax rate
  • The state’s credit outlook
  • In-state supply/demand dynamics
  • After-state-tax yields on out-of-state (national) bonds

We review these factors quarterly, updating our in-state offerings as needed to ensure the right balance of diversification, liquidity, capital preservation and attractive after-tax return potential for each investor.

High state tax rates don’t always favor state-specific portfolios

Though top marginal tax rates declined under federal tax reform, the new $10,000 cap on deductions for property, income and sales taxes paid locally is expected to raise effective tax rates in some states (see Figure 1). These include California, Connecticut, New York (especially New York City) and New Jersey, where state and local tax deductions average $18,000–$20,000 – well above the new limit.

Does this mean investors in those states should seek 100% in-state allocations to offset the impact? Not necessarily, given differences in issuance volumes and credit quality among these states. PIMCO’s forward-looking credit outlooks at both the state and issuer level are a key pillar of our municipal investment process and a critical element in how we assess our in-state offerings. We caution against a 100% allocation to states with negative credit trajectories and limited opportunities to diversify away from state credit exposure.
